Agroecology in Africa: Mitigation the Old New Way
By Frederic Mousseau
OAKLAND, California, (IPS)—Millions of African farmers don’t need to adapt to climate change. They have done that already.
Like many others across the continent, indigenous communities in Ethiopia’s Gamo Highlands are well prepared against climate variations. The high biodiversity, which forms the basis of their traditional enset-based agricultural systems, allows them to easily adjust their farming practices, including the crops they grow, to climate variations.
People in Gamo are also used to managing their environment and natural resources in sound and sustainable ways, rooted in ancestral knowledge and customs, which makes them resilient to floods or droughts. Although African indigenous systems are often perceived as backward by central governments, they have a lot of learning to offer to the rest of the world when contemplating the challenges of climate change and food insecurity.
Often building on such indigenous knowledge, farmers all over the African continent have assembled a tremendous mass of successful experiences and innovations in agriculture. These efforts have steadily been developed over the past few decades following the droughts that impacted many countries in the 1970s and 1980s.
In Kenya, the system of biointensive agriculture has been designed over the past thirty years to help smallholders grow the most food on the least land and with the least water. 200,000 Kenyan farmers, feeding over one million people, have now switched to biointensive agriculture, which allows them to use up to 90 per cent less water than in conventional agriculture and 50 to 100 per cent fewer purchased fertilizers, thanks to a set of agroecological practices that provide higher soil organic matter levels, near continuous crop soil coverage, and adequate fertility for root and plant health.
The Sahel region, bordering the Sahara Desert, is renowned for its harsh environment and the threat of desertification. What is less known is the tremendous success of the actions undertaken to curb desert encroachment, restore lands, and farmers’ livelihoods.
Started in the 1980s, the Keita Rural Development Project in Niger took some twenty years to restore ecological balance and drastically improve the agrarian economy of the area. During the period, 18 million trees were planted, the surface under woodlands increased by 300 per cent, whereas shrubby steppes and sand dunes decreased by 30 per cent. In the meantime, agricultural land was expanded by about 80 per cent.
All over the region, a multitude of projects have used agroecological solutions to restore degraded land and spare scarce water resources while at the same time increasing food production, and improving farmers’ livelihoods and resilience. In Timbuktu, Mali, the System of Rice Intensification (SRI) has reached impressive results, with yields of 9 tons of rice per hectare, more than double of conventional methods, while saving water and other inputs. In Burkina Faso, soil and water conservation techniques, including a modernized version of traditional planting pitszai have been highly successful to rehabilitate degraded soils and boost food production and incomes.
