Prof. Mwangombe (Right) and the workshop research team discussing food security in Africa at Westhouse Hotel Conference Room-Nairobi. The workshop aims to achieve higher productivity in agriculture and realize a food secure and prosperous country and continent.

Recent research provides evidence of stagnating crop yields and regionally, very heterogeneous crop yield patterns. In order to reverse this trend, it was essential to identify underperforming regions and understand key causes of poor productivity. On realizing that, Kenyan researchers from CAVS teamed up with those from Sweden, Ghana and World Agro forestry Center (ICRAF) to unravel and discuss solutions that address food insecurity. This was done in a workshop dubbed “Unraveling the Causes and Implications of Crop Productivity Gaps in Underperforming Regions through Integration of Geospatial Biophysical and Socio-Economic Factors”.

Speaking in her opening remarks, CAVS Principal, Prof. Agnes Mwang’ombe, expressed great pleasure in devotion of the research team. She was also marveled by the fact that the workshop aims to achieve higher productivity in agriculture and realize a food secure and prosperous country/continent; an element that is one of the priority development agenda for Kenya and indeed most African Countries.

In this research workshop, the general assumption was that regions where the yield gaps (difference between potential and achieved yield) are witnessed; are large, hold promise for productivity gains and increase in food security.

Owing to that, the project focused on Sub-Saharan Africa (SSA) where some of the largest yield gaps were observed. The aim was to understand the causes of observed large yield gaps and to integrate biophysical and socio-economic explanations for these. Crop yield maps were created to study variations within and between villages, landscapes, and regions, spatially and temporally. Available socio-economic panel data were combined with remote sensing and detailed investigations in selected villages in Kenya and Ghana with focus on soil conditions, management practices, labor availability and gender aspects.

CAVS is dedicated to be a leader in providing solutions to cope with projected population and income growth in the agricultural sector. It is committed towards ensuring increase in production and productivity without compromising environmental sustainability.

This Project was funded by Swedish Research Council and was a collaborative research project of University of Nairobi (through CAVS), World Agroforesry Centre (ICRAF), Swedish University of Agricultural Sciences (SLU), Lund University (Sweden), University Of Ghana and Chuka University.
