Building Resilience Through Agroecology


Dear Friends and Colleagues

Building Resilience Through Agroecology

Agriculture takes up almost 40% of the planet’s ice-free land surface, accounts for 70% of the freshwater used in the world, and produces about 30% of global greenhouse gas emissions. It is also the single biggest driver of biodiversity loss. Meanwhile, climate shocks and extreme weather events can cause food price volatility that affects both consumers and producers around the world – hitting hardest in poor countries.

Agroecology is the “ecology of the food system” and a farming approach that is inspired by natural ecosystems. There is growing evidence that agoecological farming systems keep carbon in the ground, support biodiversity, rebuild soils, and sustain yields, providing a basis for secure livelihoods. Agroecological methods can also help farmers cope with climate change by enhancing resilience.

Around the world, innovative agroecological farmers increasingly challenge the dominant industrial way of farming. Combining local and scientific knowledge, they put resilience thinking into practice to feed growing populations and cope with climate change, water scarcity, market volatility, and more.

André Gonçalves, a professor of agroecology at Instituto Federal Catarinense in Brazil conducted research in several countries and found solid practical success stories of the seven principles for building resiliencewhich are as follows: (1) Extensive use of diversity of crops, farming techniques, and livelihoods; (2) Managing connectivity; (3) Managing slow variables and feedbacks; (4) The landscape as a complex adaptive system; (5) Learning; (6); Participation; and (7) Decentralised governance. He concludes that agroecological and resilience-building approaches to agriculture are crucial for reaching the sustainable development goals.

Around the world, innovative agroecological farmers increasingly challenge the dominant industrial way of farming. Combining local and scientific knowledge, they put resilience thinking into practice to feed growing populations and cope with climate change, water scarcity, market volatility, and more.

Twelve years ago, in 2006, Haregu Gobezay was unemployed and her family with six children relied on her husband’s salary to cover all their expenses. Today, Gobezay and her husband manage a 12-hectare farm with mango, orange, mandarin, and avocado plantations in Mereb Leke District of the Tigray Region in northern Ethiopia. They also keep a few dairy cows, and chickens for egg production.

They no longer rely on a single crop. The finger millet they used to grow often suffered from weed invasions and termites, and the yield was low due to thin and nutrient-poor soils. Now they grow a wide range of different crops. This has helped them tackle many challenges, and made it possible for them to employ almost a hundred people and make a good profit from selling mango and other fruits.

Gobezay started with planting vegetables; she then added fruit trees, and peanut plants as cover crops that fertilise the soil by fixing nitrogen from the air, with the help of bacteria living in their root systems. Eventually, she brought in dairy cows and started cultivating pasture plants such as alfalfa, Rhodes grass, and elephant grass under the trees.

To improve soil fertility further and to increase soil organic matter, the family now prepares compost in 20 big pits. In addition, a biogas plant on the dairy farm produces bio-slurry compost and energy for cooking.

The family also uses “push-pull” technology as an additional source of income. The technology was developed in Africa to control Striga weeds and insect pests, particularly stemborer moths, without using chemical pesticides. It involves growing maize, sorghum or mango trees together with flowering plants such as Desmodium that repel, or “push”, the pests, and planting other plants such as elephant grass around the crops to attract, or “pull”, the pests. Desmodium eliminates Striga weeds and repels the stemborers, which are instead attracted to the elephant grass. By growing Desmodium, the family’s farm has become a source of seeds for scaling up the push-pull technology in the whole region.

More and more farmers around the world are turning away from chemical-intensive single-crop farming in favour of production methods based on diversity, local inputs of for example compost, and ecosystem services. This kind of “agroecological” farming has seen a revival in recent years as a response to the many challenges facing agriculture globally. There is growing evidence that agroecological farming systems keep carbon in the ground, support biodiversity, rebuild soils, and sustain yields, providing a basis for secure livelihoods. [1] 

Today’s agriculture produces enough food for the global population, but it has not given everyone everywhere access to sufficient, safe, and nutritious food. Agriculture has also contributed to soil degradation, a misuse of natural resources, and the crossing of crucial planetary boundaries that have kept Earth in a relatively stable state for the past 11,000 years, since before agriculture was invented.

Agriculture takes up almost 40% of the planet’s ice-free land surface, accounts for 70% of the freshwater used in the world, and produces about 30% of global greenhouse gas emissions.[2] The current food production system increases humanity’s dependency on fossil fuels and contributes to climate change. Meanwhile, climate shocks and extreme weather events can cause food price volatility that affects both consumers and producers around the world – hitting hardest in poor countries.

The agricultural system has also doubled the flows of nitrogen and phosphorus around the world predominantly through the use of chemical fertilisers, causing severe water quality problems in rivers, lakes, and the ocean. It is also the single biggest driver of biodiversity loss. A growing number of international studies and assessments stress that more attention, public funds, and policy measures should be devoted to the agroecological approach in order to avoid these negative environmental impacts.[3-7]

Strengthening the Resilience of Farmers

Agroecology is the “ecology of the food system”[8] and a farming approach that is inspired by natural ecosystems. It combines local and scientific knowledge and applies ecological and social approaches to agricultural systems, focusing on the interactions between plants, animals, humans, and the environment. Agroecological methods can also help farmers cope with climate change by enhancing resilience.

Agroecology has the explicit goal of strengthening the sustainability of all parts of the food system, from the seed and the soil, to the table, including ecological knowledge, economic viability, and social justice. To reach this goal, agroecological methods strive to minimise or exclude the use of fossil fuels, chemical inputs such as fertilisers and pesticides, and large-scale monocropping – cultivation of a single crop on vast tracts of land.

An agroecological approach includes a number of agricultural methods, such as diversification of crops, conservation tillage, green manures, natural fertilisers and nitrogen fixation, biological pest control, rainwater harvesting, and production of crops and livestock in ways that store carbon and protect forests. It also emphasises the importance of local knowledge, farmer empowerment, and socio-economic regulations, such as environmental subsidies and public procurement schemes.

Agroecology has become something of a buzzword in recent years, and the big question is: can agroecological farming feed a global population estimated to reach almost 10 billion people in the coming decades? A growing mound of evidence says yes – the approach can help change the world’s food production for the better, and produce enough foodto feed the world.

“Today’s scientific evidence demonstrates that agroecological methods outperform the use of chemical fertilisers in boosting food production where the hungry live – especially in unfavourable environments,” said Olivier De Schutter in 2011, in his role as United Nations special rapporteur on the right to food.

De Schutter and many others have also concluded that agroecology is a good way to increase the resilience of farming systems. But few have really investigated in depth how agroecology and resilience are linked in practice among smallholder farmers around the world.

In 2014 André Gonçalves, a professor of agroecology at Instituto Federal Catarinense in Brazil and technical advisor at Centro Ecológico Brazil, took part in the third international resilience conference in Montpellier in France. He became increasingly fascinated with the concept of resilience and wanted to incorporate it into his work on agroecological farming methods.

After the conference, he decided to organise a series of field trips around the world together with the Swedish Society for Nature Conservation (SSNC) and their partner organisations, to look for practical examples of how agroecological methods affect farmers’ resilience.

The field trips took place over several years and took him to Ethiopia, Kenya, Uganda, the Philippines, Sweden, and various places in his home country Brazil. His travels resulted in new insights into how innovative farmers and organisations have been using agroecological approaches to cope with the challenges of climate change and other disturbances, such as degradation of soils, pest outbreaks, chemical pollution, and escalating prices of chemical inputs such as pesticides and fertilisers.[9]

Connecting Agroecology and Resilience

Gonçalves quickly concluded that agroecology is not a one-size-fits-all solution, instead it is about taking the local socio-economic and ecological conditions into consideration.

“In my definition agroecology is all about values such as social justice and economic aspects. Otherwise, it would be reduced to the technical dimension,” Gonçalves says. To capture these aspects his analysis focused as much on social and economic measures as on ecological ones to strengthen agricultural resilience.

In 2016 he organised a workshop at the Stockholm Resilience Centre (SRC), gathering practitioners and scientists from around the world to take a closer look at how agroecology and resilience thinking relate to each other. He co-organised the workshop with Karin Höök, a senior consultant and expert in agriculture and environment at NIRAS Sweden. She has collaborated with Gonçalves since the early 2000s. Through her previous work as head of the international department at SSNC, Höök became interested in resilience thinking and how it can be applied to make agriculture more sustainable.

“Resilience theory is extremely interesting and relevant for agricultural development, but it has often come across as more of a popular buzzword than concrete real-world applications,” Höök says. “Now that is changing and we see more and more concrete tools and practical examples of how it can contribute to sustainable agricultural development.”

In 2016, Elin Enfors Kautsky, researcher and research coordinator at the SRC, co-authored a paper suggesting different ways to put resilience-based interventions into practice in agricultural landscapes.[10] The authors concluded that improving ecosystem services and the resilience of agricultural systems to a changing climate, extreme weather events, pest outbreaks, market volatility, institutional changes, and other pressures is critical to achieving a range of the UN’s sustainable development goals.

Following the workshop, where Gonçalves also met Enfors Kautsky, he continued to compare his observations and experiences from the field trips with the seven principles for building resilience,[11] which have become increasingly popular in analysing resilience and putting it into practice. The comparison revealed that certified organic farming and other agroecological approaches often go hand in hand with resilience thinking, and tended to improve both farm revenues and household income. For example, Gonçalves saw many examples of the first resilience principle in the extensive use of diversity of crops, farming techniques, and livelihoods.

Building Resilience in Agroecology

Gobezay and her husband in Ethiopia are by no means the only ones working for a diversity-based farming system. In Uganda, Gonçalves met Vicent Ssonko and Yakubu Nyende, who grow organic pineapples together with bananas and a variety of other plants such as beans, maize, and groundnuts. If the international market for organic pineapples collapses, they will still earn an income from selling bananas at the local market. Beans and groundnuts are important components of a balanced diet, increasing food security and nutrition. They also fixate nitrogen and improve soil fertility, without the need for chemical nitrogen fertilisers.

Diversity is also used to tackle other challenges. Pepito Babasa, a Philippine rice farmer from the Southern Luzon region, often experiences typhoons and floods. He makes sure he plants a diversity of different rice varieties known to withstand floods and droughts to secure his harvest.

The second principle of building resilience – managing connectivity – manifests in many ways in agroecology. Gonçalves found examples ranging from how farmers had access to markets to sell their crops, to the distance of their fields to the habitats of pollinators, and natural enemies of pests. Recycling nutrients and organic matter from one field to another is also an important way of managing connectivity in the agricultural landscape. An example of where this is put into practice can be seen in farmers making and using compost as a natural fertiliser on agroecological farms in Ethiopia. Agroecological methods also support ecological connectivity between the agricultural landscape and the surrounding forests in the Brazilian and Ugandan agroforestry systems that integrate crops, trees, and animal husbandry.

Using compost for maintaining the fertility, organic content, and water-holding capacity of soils is also an example of the third resilience principle – managing slow variables and feedbacks. In Ethiopia, the Tigray region’s innovative use of compost has earned world recognitionfor transforming an area suffering from impoverished soils, erosion, and droughts into increased harvests and incomes while improving groundwater levels, soil fertility, and biodiversity.

Gonçalves also found that farmers had a good understanding of the fourth principle: the landscape as a complex adaptive system. “To adopt agroecological practices simply requires a certain degree of complexity thinking,” he says. “While industrial agriculture is based on a linear approach and a cause and effect relationship, organic and other forms of agroecological agriculture requires a holistic view of agricultural production.”

A plant disease or pest outbreak in industrial agriculture, for example, might be seen as a direct consequence of a virus or insect, and would be controlled by using pesticides. Smallholder agroecological farmers, however, perceive diseases and pests as consequences of management, with many possible causes such as soil fertility, water availability, plant variety, and seasonal shifts.

Learning, participation, and decentralised governance – the fifth, sixth, and seventh resilience principles – were often strongly linked to each other in the farming systems Gonçalves visited. For example, the Ecovida Agroecology Network in Brazil brings together more than 5,000 farmer families in the three southernmost states of the country – Paraná, Santa Catarina and Rio Grande do Sul – in a network that promotes agroecology and sustainable, resilient use of natural resources. The farmers organise peer-to-peer learning and encourage broad participation that includes poor landless smallholders, larger farmers, and food-processing facilities.

The Ecovida network’s structure and distribution is also a classic example of polycentric governance. The network is divided into several self-governing organisations that interact, manage, and enforce rules within certification and sustainable agriculture. All individual members have a vote and all decisions in their respective organisations are taken collectively.

Similar networks connecting learning, participation, and polycentric governance were present in many other places visited by Gonçalves: PELUM is a network of civil society organisations working with grassroots communities in Kenya and nine other African countries; MASIPAG is a farmer-led network of people’s organisations in the Philippines; NOGAMU is an umbrella organisation of producers, processors, and exporters of the organic sector in Uganda; and there were several networks and organisations that promote sustainable farming in Ethiopia and in Sweden.

A Shift in the World’s Food System

Gonçalves concludes that “actively applying resilience thinking is an important basis for the agroecological farming in the case studies, making smallholder farmers less dependent on loans, fossil fuels and chemicals”.

He believes that agroecological and resilience-building approaches to agriculture are feasible alternatives to chemical-intensive monocultures, and that these methods will be crucial for reaching sustainable development goals. Several other researchers have reached similar conclusions.

Line Gordon, deputy director of the SRC, led a study published in the Environmental Research Letters journal in 2017 [12] that looked at how food production has influenced human health and nature from the 1960s until today. The researchers propose eight ways to rewire the world’s food system and rethink how we produce our food, concluding that “we need to rewire different parts of food systems, to enhance information flows between consumers and producers from local to global scales, influence food-system decision makers, and re-connect people to the biospherethrough the culture of food”.

Their suggestions include many agroecological aspects and call for better recognition and understanding of the many ecosystem services and social benefits that food-producing systems deliver beyond food itself, such as pollination, water filtration, and recreation.

More recently, the director-general of the Food and Agriculture Organization, José Graziano da Silva, also called for healthier and more sustainable food systems, mentioning agroecology as a way forward. During his opening remarks at the 2nd International Agroecology Symposiumin Rome in April 2018 he said: “We need to promote a transformative change in the way that we produce and consume food. We need to put forward sustainable food systems that offer healthy and nutritious food, and also preserve the environment. Agroecology can offer several contributions to this process.”

Graziano da Silva’s statement resonates with an article published in 2014 in Solutions magazine, [13] where a group of leading resilience researchers argued that efforts to improve short-term efficiency and optimisation in food production may be setting us up for a bigger fall down the road. “An agriculture that causes long-term or widespread environmental crises is not resilient, no matter how economically successful or how much food is produced, making its profitability and productivity irrelevant,” they wrote.

The group of researchers, led by Elena Bennett from McGill University in Canada, concluded that agriculture needs to be both resilient and sustainable, and this requires radically new approaches to agricultural development. A narrow focus on increasing production efficiency may reduce resilience, for example by degrading soils and making crops more vulnerable to pest and disease outbreaks and climate shocks. The food production system instead needs approaches and methods that produce sufficient quality and quantities of food while supporting healthy ecosystems.

Thinking less about bigger crop yields and more about resilience and sustainability also requires new metrics for evaluating the food system. This is also emphasised by Gonçalves and recently echoed by environmental economist Pavan Sukhdev in Nature where he wrote: “I never fail to be astonished at the inadequacy of the metrics we use to evaluate [food] systems. The most common yardstick is ‘productivity per hectare’. This measure of the yield or value of a particular crop relative to the area of the land on which it was grown is too narrow. We need alternatives that account for the interacting complex of agricultural lands, pastures, inland fisheries, natural ecosystems, labour, infrastructure, technology, policies, markets and traditions that are involved in growing, processing, distributing and consuming food.”

So, even though an agroecological transformation towards more resilient agriculture might come at an initial cost, it will make it possible to maintain human well-being for the long-term. A growing number of resilience researchers and practitioners argue that it is the only way to provide a diet that is healthy for both people and the planet.

The many farmers Gonçalves visited around the world represent the opportunities of this shift from a narrow productivity focus to a food production system that is both more sustainable and resilient. To be effective, it is also important that such approaches that challenge our current farming system are included in the training of next generations of farmers around the world.

“We must invest much more in resilience through participation and education of youth, for example by integrating agroecological approaches in the curricula of schools, training centers, farmer field schools, school gardens, and also at university level,” Gonçalves concludes.
