Project Description

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. In most cases, the rootable soil depth is considered to be an intrinsic soil property because it is difficult to modify the soil physical and chemical traits that restrict root growth, including high acidity or alkalinity, subsoil compaction, cemented layers, abrupt textural transitions, and bedrock. To achieve the project’s objective, a collaborative project was established among the AfSIS project and the Global Yield Gap and Water Productivity Atlas (GYGA) project, both funded by the Bill and Melinda Gates Foundation. Partners in the AfSIS project are Columbia Global Centers, ICRAF and ISRIC. Partners in the GYGA project (www.yieldgap.org) are the University of Nebraska, Wageningen University, ICRISAT, and participating institutes in 10 sub-Saharan countries. The colaborative project was led by ISRIC – World Soil Information
