West Africa

 

 

Main Contacts for Initiative: WASCAL

Heidi Webber and Dilys McCarthy  

Brief Description of Activity

Establishment of crop modelling framework to assess impacts of climate change, socio-economic and technology changes on West Africa cropping systems with ultimate ambition to engage with support policy making. Current focus is on bio-physical crop yields and landuse, with ambition to expand to include farm and market analysis.

Overview of Participants

UniBonn & WASCAL, with informal cooperation CIWARA (U Ghana, CIRAD), AgMIP, U Florida

Current Research Focus

Climate and technology impacts on cereal crops in Sudan Savanna region

Recent Noteworthy Finding

Results indicate that 2.0°C will bring lead to lower yields than 1.5°C warming scenario, with larger losses for the intensification scenario. With intensification, higher [CO2] for the 2.0°C scenario offset some losses. We found no evidence to suggest that yield variability would increase with the additional half degree of warming.

Overview of Initiative

A significant portion of the Western Africa population is smallholder, rain-fed farmers. In recent history, rainfall patterns have changed. The season has changed in length, and the frequency of rainfall has altered. The potential threat of climate change on food security is increasing for this region. The Climate Change Impact on Western African Agriculture project aims to build a pathway to simulate impacts for the Region. Phase 2 (2015-2017) work for this team focused on: the Nioro region of Senegal; advancing one site in Ghana and one in Mali regions to full regional integrated assessments; and developing national scale asessments.

Work during Phase 2 particularly emphasized stakeholder engagement. The Western Africa team worked closely with Climate Change Agriculture Food Security (CCAFS) West Africa Flagship 4 and Flagship 2 (CASCAID) projects to ensure both district and national stakeholder engagement. Stakeholder engagement was achieved through informal interactions, workshops, and interviews. These engagements helped enhance the usefulness of the research findings for stakeholders.

In addition to stakeholder engagement, the research team expanded and redeveloped Representative Agricultural Pathways (RAPs) for these regions, incorporated livestock and commodities of focus into the models, developed adaptation packages, and ensured harmonized data for the West Africa Region. The project developed effective information that can be translated directly into usable information. These information products include graphics and visuals, short summaries, and information briefs.
