Ending the Exode by BDL in Niger

While 8 out of ten Nigeriens depend on farming widespread soil degradation and climate variability make it difficult to sustain a family all year long.  Niger is used to men migrating to neighboring countries from January to April after the harvests, searching for casual labour, during what they call the Exode. Niger is also fast becoming a migration hub towards North Africa and Europe.

Niger experiences drought at least once every two years. Only one percent of the country’s land receives more than 600 mm of rain each year, and just 12 percent of land can sustain agriculture. There is an ongoing food and nutrition crisis across the Sahel and Nigeriens, especially women and their children, suffer as they have less access to productive land to produce food. More than half of Sahel lands are degraded. Nigeriens are among the poorest, but also the fastest growing population with 4% annual growth rate. Pressure on agricultural lands means farmers cultivate fragile and marginal lands. Unsustainable grazing and farming practices like the clearing of tree cover to plant staple food crops of millet and sorghum, and removal of crop residues to feed animals without alternatives to renew soil fertility have accelerated this land degradation.

In 2013, Niger launched the ambitious 3N initiative (Nigeriens Nourishing Nigeriens) to tackle this food security through “agricultural and political transformation”. More inclusive land access, as requested by the upcoming Conference on Land Policy in Africa next November, would be a good step forward. This is an urgent need for Nigerien women who have much limited access to agricultural land and farm assets, despite their central role for family nutrition.

A hard red watertight lateritic layer prevents water seeping into the soil and plants to grow. Rural communities have abandoned these degraded common lands to free-range grazing animals and firewood harvesting, as not much grain can be produced there. However, because these soils are rich in clay, they can retain water much better than the sandy soils. And could be a precious food resource during the rainy season if the compacted layer is broken. This is the rationale of the Bio-reclamation of Degraded Lands (BDL) system. BDL combines indigenous water-harvesting techniques, application of organic matter and plantation of high-value trees and vegetables. 

The idea is to restore productivity of the barren lateritic soils by using traditional water-harvesting planting techniques, like half-moons or zai pits, for the cultivation of high value vegetables and trees, instead of millets or sorghum as farmers used to do. The impact on incomes and family nutrition makes the intensive labor investment worthwhile.

Over 10,770 women have been trained in BDL, planting nutritious vegetables like okras, sorrel or protein-rich leafy vegetable Senna obtusifolia, together with drought tolerant trees like vitamin C rich Pomme de Sahel (Ziziphus mauritiana), moringa, sweet tamarind, marula or Australian acacia depending on the families’ needs. In addition to supplementary food, trees can also provide firewood or fodder, shade and live fencing to protect the farming plots against errant livestock. The other BDL innovation is to negotiate with land owners and the local authorities (village institutions and municipalities) to guarantee land use rights of degraded commons to a women’s group over a long period (fifteen years).  BDL is like a green oasis in middle of barren lands that attracts goats and other livestock that don’t have much to eat at this time. To avoid conflicts with herders, it is not recommended to use degraded lands near pasture. Because of free grazing roaming pastoralism in Niger, solid tall fencing or thorny hedges are essential to protect the plants from the start. A close source of water is essential for minimum watering of trees until they are well established. The women’s group for each plot has six trees to take care off. But too much water is not good either as trees have to develop their roots deep in the soil. Watering once a week is enough for the first 2-3 years.

 Research has shown that a 200 m2 BDL plot could yield an annual income of FCFA 50,000 (approximately 100 US dollars), which is equivalent to what men traditionally earn from millet production per hectare. A mid-term evaluation has estimated that women engaged in BDL groups have doubled their incomes compared to other non BDL families.

Impact on family nutrition is also undeniable. Vegetable and trees improve diet diversity and bring essential nutrients that the staple foods like millets and sorghum do not have. For instance, the leaves of moringa, a tree originated from Ethiopia, are packed with three times more iron than spinach and four times more calcium than milk. Women also dry surplus okras they gain during the production glut in August-September, so that they cook it later, providing nutritious food supplementation for up to 5 months during the dry season.  

Clarification of land ownership with the local authorities is also very important as in some cases, potential owners try to claim the land once the plot becomes productive. 

BDL ticks many boxes: gender, food and nutrition security and climate resilience. We need to scale up this inclusive farming practice so more families in rural Niger nurture their roots in a more food secure community.
