I. Introduction
1. In this annual report submitted to the Human Rights Council in accordance with
Council resolution 13/4, the Special Rapporteur on the right to food shows why agriculture
should be fundamentally redirected towards modes of production that are more
environmentally sustainable and socially just, and how this can be achieved. The report is
based on a large range of submissions received from experts from all regions, as well as on
an international expert seminar on agroecology convened by the Special Rapporteur in
Brussels, Belgium, on 21-22 June 2010, with support from the King Baudouin Foundation.
2. Agriculture is at a crossroads. For almost thirty years, since the early 1980s, neither
the private sector nor governments were interested in investing in agriculture. This is now
changing. Over the last few years, agri-food companies have seen an increase in direct
investment as a means to lower costs and ensure the long-term viability of supplies:1
Foreign direct investment in agriculture went from an average US$ 600 million annually in
the 1990s to an average US$ 3 billion in 2005-2007.2 The shock created by the 2007-2008
global food price crisis led to the establishment or strengthening of further initiatives, such
as the Aquila Food Security Initiative, the Global Agriculture and Food Security Program
(GAFSP) or NEPAD’s Comprehensive Africa Agriculture Development Program
(CAADP) in Africa. Governments are paying greater attention to agriculture than in the
3. But increasing food production to meet future needs, while necessary, is not
sufficient. It will not allow significant progress in combating hunger and malnutrition if it is
not combined with higher incomes and improved livelihoods for the poorest – particularly
small-scale farmers in developing countries. And short-term gains will be offset by longterm
losses if it leads to further degradation of ecosystems, threatening future ability to
maintain current levels of production. It is possible, however, to significantly improve
agricultural productivity where it has been lagging behind, and thus raise production where
it needs most to be raised (i.e. in poor, food-deficit countries3), while at the same time
improving the livelihoods of smallholder farmers and preserving ecosystems. This would
slow the trend towards urbanisation in the countries concerned, which is placing stress on
public services of these countries. It would contribute to rural development and preserve the
ability for the succeeding generation to meet its own needs. It would also contribute to the
growth of other sectors of the economy by stimulating demand for non-agricultural
products that would result from higher incomes in rural areas.
4. To achieve this, however, pouring money into agriculture will not be sufficient;
what is most important is to take steps that facilitate the transition towards a low-carbon,
resource-preserving type of agriculture that benefits the poorest farmers. This will not
happen by chance. It can only happen by design, through strategies and programmes backed
by strong political will, and informed by a right-to-food approach. This report explores how
agroecology, a mode of agricultural development that has shown notable success in the last
decade (see Section III), can play a central role in achieving this goal.

3 Although this report focuses on these countries, the Special Rapporteur is convinced that the
transition towards low external input and sustainable agriculture is needed in all regions, including
industrialized countries.
II. Diagnosis: three objectives of food systems
5. Ensuring the right to food requires the possibility either to feed oneself directly from
productive land or other natural resources, or to purchase food. This implies ensuring that
food is available, accessible and adequate. Availability relates to there being sufficient food
on the market to meet the needs. Accessibility requires both physical and economic access:
physical accessibility means that food should be accessible to all people, including the
physically vulnerable such as children, older persons or persons with disabilities; economic
accessibility means that food must be affordable without compromising other basic needs
such as education fees, medical care or housing. Adequacy requires that food satisfy dietary
needs (factoring a person’s age, living conditions, health, occupation, sex, etc), be safe for
human consumption, free of adverse substances and culturally acceptable. Participation of
food-insecure groups in the design and implementation of the policies that most affect them
is also a key dimension of the right to food.
6. Consistent with obligations assumed by States under international human rights
treaties to take effective measures towards the realization of the right to food, food systems
should be developed in order to meet the following three objectives.
7. First, food systems must ensure the availability of food for everyone, that is, supply
must match world needs. The most widely cited estimates state that an overall increase in
agricultural production should reach 70 per cent by 2050,4 taking into account demographic
growth, as well as changes in the composition of diets and consumption levels associated
with increased urbanization and higher household incomes. This estimate, however, needs
to be put in an appropriate perspective, since it takes the current demand curves as a given.
At present, nearly half of the world’s cereal production is used to produce animal feed, and
meat consumption is predicted to increase from 37.4 kg/person/year in 2000 to over 52
kg/person/year by 2050, so that by mid-century, 50 per cent of total cereal production may
go to increasing meat production.5 Therefore, reallocating cereals used in animal feed to
human consumption, a highly desirable option in developed countries where the excess
animal protein consumption is a source of public health problems, combined with the
development of alternative feeds based on new technology, waste and discards, could go a
long way towards meeting the increased needs. The United Nations Environmental
Programme (UNEP) estimates that, even accounting for the energy value of the meat
produced, the loss of calories that result from feeding cereals to animals instead of using
cereals directly as human food represents the annual calorie need for more than 3.5 billion
people.6 In addition, food losses in the field (between planting and harvesting) may be as
high as 20 to 40 per cent of the potential harvest in developing countries, due to pests and
pathogens, and the average post-harvest losses, resulting from poor storage and
conservation, amount at least to 12 per cent, and up to 50 per cent for fruits and vegetables.7
Finally, as a result of policies to promote the production and use of agrofuels, the diversion
of crops from meeting food needs to meeting energy needs contributes to tightening the
pressure on agricultural supplies. Although these are all domains in which measures could
be adopted, the need to meet the supply-side challenge remains.

8. Second, agriculture must develop in ways that increase the incomes of smallholders.
Food availability is, first and foremost, an issue at the household level, and hunger today is
mostly attributable not to stocks that are too low or to global supplies unable to meet
demand, but to poverty; increasing the incomes of the poorest is the best way to combat it.
Cross-country comparisons show that GDP growth originating in agriculture is at least
twice as effective in reducing poverty as GDP growth originating outside agriculture.8 But
some types of investments are more effective than others in achieving that objective. The
multiplier effects are significantly higher when growth is triggered by higher incomes for
smallholders, stimulating demand for goods and services from local sellers and serviceproviders.
When large estates increase their revenue, most of it is spent on imported inputs
and machinery, and much less trickles down to local traders.9 Only by supporting small
producers can we help break the vicious cycle that leads from rural poverty to the
expansion of urban slums, in which poverty breeds more poverty.
9. Third, agriculture must not compromise its ability to satisfy future needs. The loss of
biodiversity, unsustainable use of water, and pollution of soils and water are issues which
compromise the continuing ability for natural resources to support agriculture. Climate
change, which translates in more frequent and extreme weather events, such as droughts
and floods and less predictable rainfall, is already having a severe impact on the ability of
certain regions and communities to feed themselves. It is also destabilizing markets.10 The
change in average temperatures is threatening the ability of entire regions, particularly those
living from rain-fed agriculture, to maintain actual levels of agricultural production.11 Less
fresh water will be available for agricultural production, and the rise in sea level is already
causing the salinization of water in certain coastal areas, making water sources improper for
irrigation purposes. By 2080, 600 million additional people could be at risk of hunger, as a
direct result of climate change.12 In Sub-Saharan Africa, arid and semi-arid areas are
projected to increase by 60 million to 90 million hectares, while in Southern Africa, it is
estimated that yields from rain-fed agriculture could be reduced by up to 50 per cent
between 2000 and 2020.13 Losses in agricultural production in a number of developing
countries could be partially compensated by gains in other regions, but the overall result
would be a decrease of at least 3 per cent in productive capacity by the 2080s, and up to 16
per cent if the anticipated carbon fertilization effects (incorporation of carbon dioxide in the
process of photosynthesis) fail to materialize.14
10. Most efforts in the past have focused on improving seeds and ensuring that farmers
are provided with a set of inputs that can increase yields, replicating the model of industrial

processes in which external inputs serve to produce outputs in a linear model of production.
Instead, agroecology seeks to improve the sustainability of agroecosystems by mimicking
nature instead of industry.15 This report suggests that scaling up agroecological practices
can simultaneously increase farm productivity and food security, improve incomes and
rural livelihoods, and reverse the trend towards species loss and genetic erosion.
11. The following sections explain what agroecology is, and how it contributes to the
realization of the right to adequate food in its different dimensions: availability,
accessibility, adequacy, sustainability and participation (Section III). However, in moving
towards more sustainable farming systems, time is the greatest limiting factor. Whether or
not we will succeed will depend on our ability to learn faster from recent innovations and to
disseminate works more widely. Section IV is dedicated to public policies that States
should adopt to scale up agroecology.
III. Contribution of agroecology to the right to food
12. Agroecology is both a science and a set of practices. It was created by the
convergence of two scientific disciplines: agronomy and ecology. As a science,
agroecology is the “application of ecological science to the study, design and management
of sustainable agroecosystems.”16 As a set of agricultural practices, agroecology seeks ways
to enhance agricultural systems by mimicking natural processes, thus creating beneficial
biological interactions and synergies among the components of the agroecosystem. It
provides the most favourable soil conditions for plant growth, particularly by managing
organic matter and by raising soil biotic activity. The core principles of agroecology
include recycling nutrients and energy on the farm, rather than introducing external inputs;
integrating crops and livestock; diversifying species and genetic resources in
agroecosystems over time and space; and focusing on interactions and productivity across
the agricultural system, rather than focusing on individual species. Agroecology is highly
knowledge-intensive, based on techniques that are not delivered top-down but developed on
the basis of farmers’ knowledge and experimentation.
13. As a way to improve the resilience and sustainability of food systems, agroecology
is now supported by an increasingly wide range of experts within the scientific
community,17 and by international agencies and organizations, such as the United Nations
Food and Agriculture Organization (FAO), UNEP18 and Biodiversity International.19 It is
also gaining ground in countries as diverse as the United States, Brazil, Germany and

14. Agroecology is a coherent concept for designing future farming systems as it is
strongly rooted both in science and in practice, and because it shows strong connections
with the principles of the right to adequate food (Section III). It can be seen as
encompassing – or closely related to – approaches such as “ecoagriculture”21 and
“evergreen agriculture,”22 while the concepts of “ecological intensification” and
“conservation agriculture” often follow certain agroecological principles. Agroecology is
also linked to the “ecosystem approach to sustainable crop production intensification”
recently supported by the FAO Committee on Agriculture (COAG).23 Discussion of the
detailed differences among these concepts is beyond the scope of this report.
15. Crop breeding and agroecology are complementary. For instance, breeding provides
new varieties with shorter growing cycles, which enable farmers to continue farming in
regions where the crop season has already shrunk. Breeding can also improve the level of
drought resistance in plant varieties, an asset for countries where lack of water is a limiting
factor. Reinvesting in agricultural research must consequently mean continued efforts in
breeding. However, agroecology is more overarching as it supports building droughtresistant
agricultural systems (including soils, plants, agrobiodiversity, etc.), not just
drought-resistant plants.
A. Availability: agroecology raises productivity at field level
16. A wide panoply of techniques based on the agroecological perspective have been
developed and successfully tested in a range of regions.24 These approaches involve the
maintenance or introduction of agricultural biodiversity (diversity of crops, livestock,
agroforestry, fish, pollinators, insects, soil biota and other components that occur in and
around production systems) to achieve the desired results in production and sustainability.
Integrated nutrient management reconciles the need to fix nitrogen within farm systems
with the import of inorganic and organic sources of nutrients and the reduction of nutrient
losses through erosion control. Agroforestry incorporates multifunctional trees into
agricultural systems. In Tanzania, 350,000 hectares of land have been rehabilitated in the
Western provinces of Shinyanga and Tabora using agroforestry;25 there are similar largescale
projects developed in other countries including Malawi, Mozambique and Zambia.26
Water harvesting in dryland areas allows for the cultivation of formerly abandoned and
degraded lands, and improves the water productivity of crops. In West Africa, stone
barriers built alongside fields slow down runoff water during the rainy season, allowing an
improvement of soil moisture, the replenishment of water tables, and reductions in soil
erosion. The water retention capacity is multiplied five- to ten-fold, the biomass production

multiplies by 10 to 15 times, and livestock can feed on the grass that grows along the stone
barriers after the rains. 27 Integration of livestock into farming systems, such as dairy cattle,
pigs and poultry, provides a source of protein to the family, as well as a means of fertilizing
soils; so does the incorporation of fish, shrimps and other aquatic resources into farm
systems, such as irrigated rice fields and fish ponds.
17. Such resource-conserving, low-external-input techniques have a proven potential to
significantly improve yields. In what may be the most systematic study of the potential of
such techniques to date, Jules Pretty et al. compared the impacts of 286 recent sustainable
agriculture projects in 57 poor countries covering 37 million hectares (3 per cent of the
cultivated area in developing countries). They found that such interventions increased
productivity on 12.6 millions farms, with an average crop increase of 79 per cent, while
improving the supply of critical environmental services.28 Disaggregated data from this
research showed that average food production per household rose by 1.7 tonnes per year
(up by 73 per cent) for 4.42 million small farmers growing cereals and roots on 3.6 million
hectares, and that increase in food production was 17 tonnes per year (up 150 per cent) for
146,000 farmers on 542,000 hectares cultivating roots (potato, sweet potato, cassava). After
UNCTAD and UNEP reanalyzed the database to produce a summary of the impacts in
Africa, it was found that the average crop yield increase was even higher for these projects
than the global average of 79 per cent at 116 per cent increase for all African projects and
128 per cent increase for projects in East Africa.29
18. The most recent large-scale study points to the same conclusions. Research
commissioned by the Foresight Global Food and Farming Futures project of the UK
Government reviewed 40 projects in 20 African countries where sustainable intensification
was developed during the 2000s. The projects included crop improvements (particularly
improvements through participatory plant breeding on hitherto neglected orphan crops30),
integrated pest management, soil conservation and agro-forestry. By early 2010, these
projects had documented benefits for 10.39 million farmers and their families and
improvements on approximately 12.75 million hectares. Crop yields more than doubled on
average (increasing 2.13-fold) over a period of 3-10 years, resulting in an increase in
aggregate food production of 5.79 million tonnes per year, equivalent to 557 kg per farming
19. Sometimes, seemingly minor innovations can provide high returns. In Kenya,
researchers and farmers developed the “push-pull” strategy to control parasitic weeds and
insects that damage the crops. The strategy consists in “pushing” away pests from corn by
inter-planting corn with insect-repellent crops like Desmodium, while “pulling” them
towards small plots of Napier grass, a plant that excretes a sticky gum which both attracts

and traps pests. The system not only controls pests but has other benefits as well, because
Desmodium can be used as fodder for livestock. The push-pull strategy doubles maize
yields and milk production while, at the same time, improves the soil. The system has
already spread to more than 10,000 households in East Africa by means of town meetings,
national radio broadcasts and farmer field schools.32 In Japan, farmers found that ducks and
fish were as effective as pesticide for controlling insects in rice paddies, while providing
additional protein for their families. The ducks eat weeds, weed seeds, insects, and other
pests, thus reducing weeding labour, otherwise done by hand by women, and duck
droppings provide plant nutrients. The system has been adopted in China, India, and the
Philippines. In Bangladesh, the International Rice Research Institute reports 20 per cent
higher crops yields, and net incomes on a cash cost basis have increased by 80 per cent.33
20. Agroecology is also gaining ground in Malawi, a country that has been at the centre
of attention in recent years. Malawi successfully launched a fertilizer subsidy programme in
2005-2006, following the dramatic food crisis due to drought in 2004-2005. However, it is
now implementing agroforestry systems, using nitrogen-fixing trees, to ensure sustained
growth in maize production in preparation for the medium-term situation when fertilizer
subsidies may have to be scaled back or withdrawn.34 By mid-2009, over 120,000
Malawian farmers had received training and tree materials from the programme, and
support from Ireland has now enabled extension of the programme to 40 per cent of
Malawi’s districts, benefiting 1.3 million of the poorest people. Research shows that this
results in increased yields from 1 t/ha to 2–3 t/ha, even if farmers cannot afford commercial
nitrogen fertilizers. With an application of a quarter-dose of mineral fertilizer, maize yields
may surpass 4 t/ha. However, this shows that, while investment in organic fertilizing
techniques should be a priority, this should not exclude the use of other fertilizers. An
optimal solution that could be an exit strategy from fertilizer subsidy schemes would be to
link fertilizer subsidies directly to agroforestry investments on the farm in order to provide
for long-term sustainability in nutrient supply, and to build up soil health as the basis for
sustained yields and improved efficiency of fertilizer response.35 Malawi is reportedly
exploring this “subsidy to sustainability” approach.36
B. Accessibility: agroecology reduces rural poverty
Sustainable on-farm fertility management
21. By enhancing on-farm fertility production, agroecology reduces farmers’ reliance on
external inputs and state subsidies. This, in turn, makes vulnerable smallholders less

dependent on local retailers and moneylenders. One key reason why agroecology helps to
support incomes in rural areas is because it promotes on-farm fertility generation. Indeed,
supplying nutrients to the soil does not necessarily require adding mineral fertilizers. It can
be done by applying livestock manure or by growing green manures. Farmers can also
establish a “fertilizer factory in the fields” by planting trees that take nitrogen out of the air
and “fix” it in their leaves, which are subsequently incorporated into the soil. That, in
essence, is the result of planting Faidherbia albida, a nitrogen-fixing acacia species
indigenous to Africa and widespread throughout the continent. Since this tree goes dormant
and sheds its foliage during the early rainy season at the time when field crops are being
established, it does not compete significantly with them for light, nutrients or water during
the growing season; yet it allows a significant increase in yields of the maize with which it
is combined, particularly in conditions of low soil fertility. In Zambia, unfertilized maize
yields in the vicinity of Faidherbia trees averaged 4.1 t/ha, compared to 1.3 t/ha nearby, but
beyond the tree canopy. Similar results were observed in Malawi, where this tree was also
widely used. The use of such nitrogen-fixing trees avoids dependence on synthetic
fertilizers, the price of which has been increasingly high and volatile over the past few
years, exceeding food commodity prices, even when the latter reached a peak in July 2008.
In this way, whatever financial assets the household has can be used on other essentials,
such as education or medicine.

22. Agroforestry or comparable techniques such as the use of leguminous-cover crops to
fix nitrogen also have a huge potential.37 This matters particularly to the poorest farmers,
who are least likely to be able to afford to buy inorganic fertilizers, and whom fertilizer
distribution systems often do not reach, particularly since the private sector is unlikely to
invest into the most remote areas where communication routes are poor and few economies
of scale can be achieved. But it is also of great importance to low-income countries, which
import to meet their inorganic fertilizer needs. In sub-Saharan Africa, part of the reason
why the use of fertilizers is very low (average 13 kilograms (kg) of fertilizer nutrients per
hectare)38 is because of the considerable fiscal costs involved in the import and distribution
of fertilizers.
Multiplier effects for rural development: job creation, increased incomes
23. Agroecological approaches can be labour-intensive during their launching period,
due to the complexity of the tasks of managing different plants and animals on the farm,
and recycling the waste produced. However, research shows that the higher labour-intensity
of agroecology is a reality particularly in the short term.39 In addition, while labour-saving
policies have generally been prioritized by governments, creation of employment in rural
areas in developing countries, where underemployment is currently massive, and
demographic growth remains high, may constitute an advantage rather than a liability and
may slow down rural-urban migration. Moreover, the cost of creating jobs in agriculture is
often significantly lower than in other sectors: in Brazil, data from INCRA, the agency
responsible for land reform, showed that each job generated in a settlement costs the
government 3.640 USD, while the cost would be 128 per cent more expensive in industry,
190 per cent more in trade, and 240 per cent more in services.40 According to peasant
organizations, agroecology is also more attractive to farmers, because it procures pleasant
features for those working the land for long hours, such as shade from trees or the absence
of smell and toxicity from chemicals.41
24. In Burkina Faso, rather than migrating, work groups of young men specialized in
land rehabilitation techniques, such as tassas and zai planting pits, go from village to village
to satisfy farmers’ growing interest in improving their own lands. Farmers are now buying
degraded land for improvement and paying these labourers to dig zai pits and construct the
rock walls and half-moon structures which can transform yields.42 This is one of the reasons
why more than 3 million hectares of land in Burkina Faso are now rehabilitated and

25. Although they can create jobs, agroecological approaches are fully compatible with
a gradual mechanization of farming. The need to produce equipment for conservation
agricultural techniques such as no-till and direct seeding actually results in more jobs being
created in the manufacturing sector. This is true in particular in Africa which still imports
most of its equipment, but which increasingly manufactures simple equipment43
Employment could also result from the expansion of agroforestry. In Southern Africa,
farmers produce trees as a business, supported by a financing facility established by the
World Agroforestry Centre (ICRAF). During its first year, the Malawi Agroforestry Food
Security Programme distributed tree seeds, setting up 17 nurseries that raised 2,180,000
seedlings and establishing 345 farmer groups.44
C. Adequacy: agroecology contributes to improving nutrition
26. In the past, Green Revolution approaches have focused primarily on boosting cereal
crops. However, rice, wheat and maize are mainly sources of carbohydrates: they contain
relatively little protein, and few of the other nutrients essential for adequate diets. The shift
from diversified cropping systems to simplified cereal-based systems thus contributed to
micronutrient malnutrition in many developing countries.45 Indeed, of the over 80,000 plant
species available to humans, rice, wheat and maize supply the bulk of our protein and
energy needs.46 Nutritionists now increasingly insist on the need for more diverse agroecosystems,
in order to ensure a more diversified nutrient output of the farming systems.47
27. The diversity of species on farms managed following agroecological principles, as
well as in urban or peri-urban agriculture, is an important asset in this regard. For example,
it has been estimated that indigenous fruits contribute on average about 42 per cent of the
natural food-basket that rural households rely on in southern Africa.48 This is not only an
important source of vitamins and other micronutrients, but it also may be critical for
sustenance during lean seasons. Nutritional diversity, enabled by increased diversity in the
field, is of particular importance to children and women.
D. Sustainability: agroecology contributes to adapting to climate change
28. Agroecology improves resilience to climate change. Climate change means more
extreme weather-related events. The use of agroecological techniques can significantly
cushion the negative impacts of such events, for resilience is strengthened by the use and
43 In East Africa, this development was facilitated by the exchange of technology from Brazilian
manufacturers to their counterparts in East Africa: see Brian Sims et al., “Agroforestry and

promotion of agricultural biodiversity at ecosystem, farm system and farmer field levels,
which is materialized by many agroecological approaches.49 Following Hurricane Mitch in
1998, a large-scale study on 180 communities of smallholders from southern to northern
Nicaragua demonstrated that farming plots cropped with simple agroecological methods
(including rock bunds or dikes, green manure, crop rotation and the incorporation of
stubble, ditches, terraces, barriers, mulch, legumes, trees, plowing parallel to the slope, noburn,
live fences, and zero-tillage) had on average 40 per cent more topsoil, higher field
moisture, less erosion and lower economic losses than control plots on conventional farms.
On average, agroecological plots lost 18 per cent less arable land to landslides than
conventional plots and had 69 per cent less gully erosion compared to conventional farms.50
29. More frequent and more severe droughts and floods can be expected in the future;
agroecological modes of farming are better equipped to support such shocks. The
agroforestry programme developed in Malawi protected farmers from crop failure after
droughts, thanks to the improved soil filtration it allowed.51 Indeed, on-farm experiments in
Ethiopia, India, and the Netherlands have demonstrated that the physical properties of soils
on organic farms improved the drought resistance of crops.52
30. In addition, the diversity of species and of farm activities that agroecological
approaches allow are ways to mitigate risks from extreme weather events, as well as from
the invasion of new pests, weeds and diseases, that will result from global warming. The
agroecological practice of cultivar mixtures bets on genetic diversity in the fields in order to
improve crop resistance to diseases. In the Yunnan Province in China, after diseasesusceptible
rice varieties were planted in mixtures with resistant varieties, yields improved
by 89 per cent and rice blast disease was 94 per cent less severe than when the varieties
were grown in monoculture, leading farmers to abandon the use of fungicidal sprays.53
31. Agroecology also puts agriculture on the path of sustainability by delinking food
production from the reliance on fossil energy (oil and gas). It contributes to mitigating
climate change, both by increasing carbon sinks in soil organic matter and above-ground
biomass, and by avoiding carbon dioxide or other greenhouse gas emissions from farms by
reducing direct and indirect energy use. The Intergovernmental Panel on Climate Change
(IPCC) has estimated the global technical mitigation potential for agriculture at 5.5 to 6 Gt
of CO2-equivalent per year by 2030.54 Most of this total (89 per cent) can come from

carbon sequestration in soils, storing carbon as soil organic matter (humus), something
which can be done through agroecology.55
E. Farmer participation: an asset for the dissemination of best practices
32. The participation of farmers is vital for the success of agroecological practices. So
far, agroecology has been developed by grassroots organizations and NGOs, and it has
spread through farmer field schools and farmers’ movements, such as the Campesino a
Campesino movement in Central America.56 Experience with agroecological techniques is
growing everyday within peasant networks such as La Via Campesina and the AgriCultures
Network (former LEISA) globally; Réseau des Organisations Paysannes et des Producteurs
Agricoles de l’Afrique de l’Ouest (ROPPA), Eastern & Southern Africa Farmers’ Forum
(ESAFF), and PELUM (Participatory Ecological Land Use Management) network in
Africa, MASIPAG network in the Philippines (Magsasaka at Siyentista Tungo sa Pag-unlad
ng Agrikultura), or Assessoria e Serviços a Projetos em Agricultura Alternativa (AS-PTA)
and Movimento dos Trabalhadores Sem Terra (MST) in Brazil.57
33. Farmer field schools have been shown to significantly reduce the amounts of
pesticides use, as inputs are being replaced by knowledge. Large-scale studies from
Indonesia, Vietnam and Bangladesh recorded 35 to 92 per cent reduction in insecticide use
in rice, and 34 to 66 per cent reduction in pesticide use, combined with 4 to 14 per cent
better yields recorded in cotton production in China, India and Pakistan.58 Farmer field
schools have also proven to be empowering by helping farmers to organize themselves
better, and stimulating continued learning. The successful dissemination of the push-pull
strategy (PPS) in East Africa, promoted by the International Centre for Insect Physiology
and Ecology (ICIPE), is largely due to the demonstration of fields managed by model
farmers, which attracts visits by other farmers during field days, and to partnerships with
national research systems in Tanzania, Uganda, Ethiopia and other countries that have
made research and development efforts to bring about the necessary adaptations such as
choice of maize cultivars.59 The growth of the Campesino a Campesino movement in Cuba
relied on technical advisers and coordinators supported by the National Association of
Small Farmers (ANAB). Between 2001 and 2009, the number of “promotores” increased

from 114 to 11,935, and a total of 121,000 workshops on agroecological practices were
34. State support can build on those efforts. In Brazil, for example, the 2010 Act on
extension and technical assistance for family farming and agrarian reform (Lei
12.188/2010)61 prioritizes support to rural extension activities in ecological agriculture. This
Act will accentuate the qualitative shift in the Brazilian extension services which is parallel
to quantitative changes in the last decade. Indeed, extension activities organized under the
Brazilian National Rural Extension Policy (2003) have increased from an average of 2,000
activities/year in 2004-2005 to an average of close to 30,000/year in 2007-2009.62 Such
efforts enable a rapid dissemination of best practices, including agroecological practices,
especially when farmers participate in the system and are not mere receivers of trainings.
IV. Public policies for the scaling up of agroecology
35. Scaling up agroecology in order to maximize its positive impacts on farmers’
incomes, productivity and the environment means both (horizontally) increasing the areas
cultivated by agroecological techniques and (vertically) creating an enabling framework for
the farmers. Innovative ways of ensuring horizontal expansion include the “pilot scaling
up” strategy such as the one successfully implemented in the Chinyanja Triangle
(Mozambique, Malawi and Zambia) and West and Central Africa by the World
Agroforestry Centre for tree domestication. The strategy relies on the identification of Pilot
Scaling Up Areas (PSUAs) and the establishment of “scaling up platforms,” the formation
of “change teams” and the identification of partners: from grassroots organization to private
companies.63 The targeting of the zones where the adoption of agroecology has the greatest
potential, based on biophysical criteria, may be facilitated by Geographic Information
Systems (GIS), such as those that have been used both in Europe and in Southern Africa in
order to identify the suitability areas for the scaling up of agroforestry systems.64 As
mentioned earlier, the dissemination of the push-pull strategy in East Africa by the
International Centre for Insect Physiology and Ecology (ICIPE) was based both on
demonstration fields managed by model farmers, which attracts visits by other farmers
during field days, and on partnerships with national research systems in neighbouring
countries that facilitated take-up of this approach. Localized innovations can spread rapidly
through such approaches (see Figure 2 below).

36. This report focuses on the vertical dimension of scaling up agroecology, namely, the
establishment of an enabling framework – although this is both a condition and a driver of
horizontal scaling up. Governments have a key role to play in this regard, beyond
supporting access to land, water and seeds for small-scale farmers.66 This section identifies
a number of principles that could support the scaling up of agroecological practices.
Encouraging a shift towards sustainable agriculture may be a delicate process associated
with transition costs, since farmers must learn new techniques that move away from the
current systems, which are more specialized, less adaptive, and have a lower innovation
capacity.67 Therefore, the following principles should be applied with flexibility. The
incentive structures which such policies create to encourage the shift towards sustainable
farming should be regularly tested and re-evaluated with the participation of the
beneficiaries, transforming policy into a mode of “social learning rather than an exercise of
political authority.”68 The move towards agroecology should be based on the farmers
themselves – its main beneficiaries. Agroecological techniques are best spread from farmer
to farmer, since they are often specific to an agroecological zone.
A. Prioritizing public goods
37. Agroecological practices require the supply of public goods such as extension
services, storage facilities, rural infrastructure (roads, electricity, information and
communication technologies) and therefore access to regional and local markets, access to
credit and insurance against weather-related risks, agricultural research and development,
education, and support to farmer’s organizations and cooperatives. While this requires
funding, the investment can be significantly more sustainable than the provision of private

goods, such as fertilizers or pesticides that farmers can only afford so long as they are
subsidized. While many efforts have been made since 2008 to reinvest in agriculture, too
little attention has been paid to the differences between the various types of investment
required and to understanding their impacts on the reduction of rural poverty. This has led
World Bank economists to note that “underinvestment in agriculture is […] compounded
by extensive misinvestment”69 with a bias towards the provision of private goods,
sometimes motivated by political considerations.70 Research based on the study of 15 Latin
American countries over the period 1985–2001 in which government subsidies for private
goods was distinguished from expenditures in public goods indicated that, within a fixed
national agriculture budget, a reallocation of 10 per cent of spending to supplying public
goods increases agricultural per capita income by 5 per cent, while a 10 per cent increase in
public spending on agriculture, keeping the spending composition constant, increases per
capita agricultural income by only 2 per cent.71 In other words, “even without changing
overall expenditures, governments can improve the economic performance of their
agricultural sectors by devoting a greater share of those expenditures to social services and
public goods instead of non-social subsidies.”72 Thus, while the provision or subsidization
of private goods may be necessary up to a point, the opportunity costs should be carefully
B. Investing in knowledge
38. Agroecology is knowledge-intensive. It requires the development of both ecological
literacy and decision-making skills in farmer communities. Investments in agricultural
extension and agricultural research are key in this regard. While agricultural spending is
among the four top contributors to increasing rural welfare, along with public spending in
education, health and roads,73 agricultural research has the greatest overall impact on
poverty and agricultural productivity in developing countries. Agricultural research had
“the largest impact on agricultural production and second-largest impact on poverty
reduction (after rural education) in China, and the second-largest impact on poverty
reduction in rural India (after investment in roads).”74 Research in agroecological practices,
in particular, should be prioritized, because of the considerable and largely untapped
potential of such practices. Modern science combines with local knowledge in
agroecological research. In Central America for instance, the coffee groves grown under
high-canopy trees were improved by the identification of the optimal shade conditions,
minimizing the entire pest complex and maximizing the beneficial microflora and fauna
while maximizing yield and coffee quality.75 However, perhaps because such practices

cannot be rewarded by patents, the private sector has been largely absent from this line of
C. Strengthening social organisation by co-construction
39. Agroecological practices are best adopted when they are not imposed top-down but
shared from farmer to farmer. Extension services play a key role in favouring the scaling up
of agroecology. An improved dissemination of knowledge by horizontal means transforms
the nature of knowledge itself, which becomes the product of a network.77 It should
encourage farmers, particularly small-scale farmers, living in the most remote areas to
identify innovative solutions, by working with experts towards a co-construction of
knowledge to ensure that advances will benefit them as a matter of priority, rather than only
benefiting the better-off producers.78 Co-construction is key for the realization of the right
to food. First, it enables public authorities to benefit from the experience and insights of the
farmers. Rather than treating smallholder farmers as beneficiaries of aid, they should be
seen as experts with knowledge that is complementary to formalized expertise. Second, as
the Special Rapporteur has previously illustrated in describing participatory plantbreeding,
79 participation can ensure that policies and programmes are truly responsive to
the needs of vulnerable groups, who will question projects that fail to improve their
situation. Third, participation empowers the poor – a vital step towards poverty alleviation.
Lack of power is a source of poverty, as marginal communities often receive less support
than the groups that are better connected to government. Poverty exacerbates this lack of
power, creating a vicious circle of further disempowerment. Fourth, policies that are codesigned
with farmers have a high degree of legitimacy and thus favour better planning of
investment and production and better up-take by other farmers.80 Participation of foodinsecure
groups in the policies that affect them should become a crucial element of all food
security policies, from policy design to the assessment of results to the decision on research
priorities. Indeed, improving the situation of millions of food-insecure peasants cannot be
done without them.
40. The best of what scientists can offer and the valuable experience of smallholder
farmers should be brought together in order to develop participatory modes of learning. The
development of participation can go beyond the field technology itself. In West Africa, for
instance, citizens’ juries on the governance of food and agricultural research were set up by
the International Institute for Environment and Development (IIED), the Coordination
Nationale des Organisations Paysannes (CNOP) and other partners, resulting in farmers
formulating 100 recommendations after having heard experts on the models of agriculture,
land tenure and property rights, macroeconomic issues and the governance of agricultural

research.81 Not only research and extension services should develop into learning
organisations, so too should ministries, and educational and financial institutions.82
Farmers’ organizations and networks have accumulated experience on the dissemination of
agroecological practices in the last decade, with proven results. These movements are
already functioning as learning organizations; they must now be supported in this role.
D. Gender empowerment
41. Specific, targeted schemes should ensure that women are empowered and
encouraged to participate in this construction of knowledge. Culturally-sensitive
participatory initiatives with female project staff and all-female working groups, and an
increase in locally-recruited female agricultural extension staff and village motivators
facing fewer cultural and language barriers, should counterbalance the greater access that
men have to formal sources of agricultural knowledge.83 It is a source of concern to the
Special Rapporteur that, while women face a number of specific obstacles (poor access to
capital and land, the double burden of work in their productive and family roles, and low
participation in decision-making), gender issues are incorporated into less than 10 per cent
of development assistance in agriculture, and women farmers receive only 5 per cent of
agricultural extension services worldwide.84 In principle, agroecology can benefit women
most, because it is they who encounter most difficulties in accessing external inputs or
subsidies. But their ability to benefit should not be treated as automatic; it requires that
affirmative action directed specifically towards women be taken.
E. Organizing markets
42. In previous reports, the Special Rapporteur has insisted on the need to facilitate the
ability of small-scale farmers to join supply chains.85 Farmers should also be encouraged to
move up the value chain by adding value to raw products through assuming increased roles
in packaging, processing, and marketing their produce. Cooperatives can help them achieve
economies of scale to facilitate adding value.86 This can also be supported by novel types of
partnerships with the private sector. However, improved access to markets is essential if
this is to happen. Better access to markets requires the development of communication
routes, particularly rural feeder roads. The marginal returns to public spending on feeder
roads for agriculture output and poverty reduction has been estimated to be “three to four
times larger than the return to public spending on murram and tarmac roads.”87 In addition,
support for agroecological practices will fail to achieve the desired results if markets are not
organized to protect farmers from volatile prices and the dumping of subsidized products on

their local markets, which can seriously disrupt local production.88 Similarly, public
procurement systems, fiscal incentives and credit, and land tenure policies – all areas on
which the Special Rapporteur has made contributions in the past – must be aligned with the
need to make the transition towards low-carbon and low-external-input modes of
production in which farmers co-design the policies that affect them. The school-feeding
programme in Brazil for instance, has been used as a leverage to support family farming
through its public procurement scheme; future public procurements schemes should
promote agroecological practices.89
IV. Recommendations
43. Moving towards sustainability is vital for future food security and an essential
component of the right to food. But in order to succeed in this transformation,
consistency will be required across a variety of areas. States will need to invest in
multi-year efforts, based on strategies identifying the measures that should be adopted
in order to make this transition.
44. As part of their obligation to devote the maximum of their available resources
to the progressive realization of the right to food, States should implement public
policies supporting the adoption of agroecological practices by:
