Achievements since last year: − Large area forest and land use assessment with many similarities to FAO National Forest monitoring completed in early 2010. − Acquisition of high resolution satellite imagery as reference for up scaling approach. Current work: − Analysis of vegetation data as input for modeling subprojects. − Land use classification, following FAO standards based on inventory results, combined with remote sensing data for modeling with climate modeling results. Adaptation of African Agriculture to Climate Change | 2-3.05.2010 | Nairobi Small scale structures of vegetation CeTSAF Objectives: Assessment and analysis of current pasture resources for livestock and prediction of their future development Achievements since last year: - Vegetation types in pastured sites of 4 core study areas (climatic gradient subsahel to southern sudanian zone) are identified and species composition is assessed - Herbaceous biomass of main vegetation types in 4 core areas is assessed at the end of the rainy season Current work and future outlook: - Assessment of herbaceous pasture resources - Assessment of ligneous biomass (fodder resource) in 4 core areas - Prediction of future development of important fodder species (Modeling with climate change predictions) Adaptation of African Agriculture to Climate Change | 2-3.05.2010 | Nairobi Animal husbandry CeTSAF Objectives: Assessment of grazing behaviour and livestock management practices. Achievements since last year: − The baseline survey at the six pre-selected research sites was carried out by the PhD Student of livestock group. − Four out of the six sites were maintained for regular monitoring of livestock grazing behaviour and for in-depth analysis of farmers’ livestock management practices. − Fodder species assessment. Current work and future outlook: − Continued monitoring of grazing and management practices until end of coming rainy season. − Assessment of main fodder species during grazing. Adaptation of African Agriculture to Climate Change | 2-3.05.2010 | Nairobi Past climatic variation assessment for model verification and plant growth Objectives: To evaluate the adaptation of the species to extreme drought events and potential of stable isotopes and tree rings for paleoclimatic reconstructions. Stem disc of: Sclerocarya birea Contribution to the Project : Will recommend drought tolerant multipurpose species for resilient agroforesty systems and provide past climate information to understand climate change. Results of the second year and/or ongoing activities: Ring width, stable isotope and plant water potential measurements and analysis is going on.
