Rooting for food security in Sub-Saharan Africa

2018-04-19T16:02:33+00:00

There is a persistent narrative about the potential of Sub-Saharan Africa (SSA) to be a 'grain breadbasket' because of large gaps between current low yields and yield potential with good management, and vast land resources with adequate rainfall.

Mapping root depth soil water in sub-Saharan Africa

Soil root zone plant-available water holding capacity (RZ-PAWHC) is one of the most sensitive soil parameters determining crop growth. This study produced the first map of the rootable depth and the RZ-PAWHC of sub-Saharan Africa (SSA).

Soil information to feed the African soil, crop and people

The ongoing debate about improving food security in Sub-Saharan Africa (SSA) is about how to enrich its soils. A core challenge within the risk-averse smallholder farming systems prevailing in SSA is to judiciously combine mineral with bio-organic nutrient applications and close nutrient cycles to improve soil health, hence crop productivity, with high and preferably known yearly likeliness of direct return on investment.

Root zone plant-available water holding capacity of the Sub-Saharan Africa soil, version 1.0. Gridded functional soil information

The objective of this project is to produce a robust, quantitative framework, which is updateable and spatially explicit, to generate and maintain functional soil information on root zone depth and associated plant available soil water holding capacity for a major rainfed staple food crop (maize) in sub-Saharan Africa.

The upsurge of soil science and the new global soil map

2018-04-26T16:16:13+00:00

There has been widespread pessimism on the status of soil science in most parts of the world. This was mainly due to dwindling research budgets, reduced number of students and the perception that soil science and pedology were dead and buried.
