Integrated nutrient management (INM) is being promoted in Sub-Saharan Africa. The authors examined INM practices among farmers in the savannas of northern Nigeria in the hope of making suggestions to improve the impact of INM practices on soil fertility. The results indicate that, although the various components of INM are available in the farming systems, only a partial integration is occurring with limited impact on soil fertility. The major constraints include: the harsh savanna environment, lack of supportive institutions and labour, high fertilizer prices and inadequate availability of organic manure. Strip cropping of improved sorghum (Sorghum bicolor) and dual-purpose cowpea (Vigna unguiculata L.) and integrated fertility management using neem foliage and half the recommended fertilizer rate have great potential. The study recommends more research, extension and policies to enhance the adoption and impact of INM practices.

Abstract Soil fertility provides the foundation for nutritious food production and resilient and sustainable livelihoods. A comprehensive survey and summit meeting were conducted with the aims of understanding barriers to enhancing soil fertility in sub-Saharan Africa and providing evidence-based recommendations. The focus regions were West Africa, East Africa, the Great Lakes region, and Ethiopia. Overall recommendations were developed with four emerging themes: (1) strengthening inorganic fertilizer-based systems, (2) access to and use of quality organic inputs, (3) capacity building along the entire knowledge-transfer value chain, and (4) strengthening farming systems research and development across biophysical and socio-economic factors. The evidence-based process and methodology for prioritizing these recommendations makes these findings useful for setting out action plans for future investments and strategies. Access to inorganic fertilizer, its use, and related implementation issues were prominent considerations; nevertheless, biophysical and socio-economic barriers and solutions were identified as equally important to building soil fertility and natural resources. Soil management initiatives should focus on providing holistic solutions covering both biophysical and socio-economic aspects along the entire value chain of actors and creating an enabling environment for adoption. A broader view of soil fertility improvement using all available options including both inorganic and organic sources of nutrients and farming system approaches are highly recommended.

The article considers the impact of the colonial past of some countries in sub-Saharan Africa and its effect on their development during the post-colonial period. The negative consequences of the geopolitical legacy of colonialism are shown on the example of three countries: Nigeria, the Democratic Republic of the Congo and the Republic of Angola, expressed in the emergence of conflicts in these countries based on ethno-cultural, religious and socio-economic contradictions. At the same time, the focus is made on the economic factor and the consequences of the consumer policy of the former metropolises pursuing their mercantile interests were mixed.
