Road Map to Promoting Green Revolution in Sub-Saharan Africa
摘要
There is an urgent need to translate the known and proven technologies into strategies for improving soil health, increasing crop productivity for food and nutritional security, environmental sustainability, economic viability, and resilience to climate change and thus promoting Green Revolution in SSA. SSA is most vulnerable to climate change and changes in the distribution and magnitude of extreme rainfall events and drought, and changes in land use/cover are the major causes of soil degradation, aridity, and land desertification. Food insecurity and undernourishment situations are on the rise in Africa, being most serious in SSA. The rising African population, coupled with the changing food preferences, imply that food production must more than double than that in 2020 to meet the food needs in 2050. Therefore, policies to incentivize farmers to adopt proven technologies which are essential to protecting, restoring, and sustainably managing finite and fragile soil resources in harsh environments are needed, and practices of regenerative agriculture based on sound principles of agroecology must be encouraged. Such policies must be pro-nature, pro-agriculture, and pro-farmers. Furthermore, upscaling of management practices, e.g. conservation agriculture, agroforestry, precision/digital agriculture for fertilizers and irrigation use in SSA, are needed to meet the growing demands for food and nutritional security of the growing SSA population.
