Methodology

A Farmer Preferred Variety Both For Grain And Livestock Feed In Tanzania

CALESA will evaluate agricultural adaptation strategies to climate change through the use of “analogue locations”, with special reference to predicted temperature increases. In this respect, a clear relationship between altitude, air temperatures, crop growth and yield facilitates the identification of appropriate temperature analogue locations in eastern and southern Africa. This work will be undertaken in close collaboration with the partners in Kenya, Zimbabwe and Hamburg.

Across Kenya and Zimbabwe, analogue locations for four production areas which currently experience cool/dry, cool/wet, warm/dry and warm/wet growing conditions have been identified.

  • Criteria for the selection of these locations will be developed and four pairs of analogue location have been identified
  • Based on long-term daily climate data, detailed climate risk and climate trend analyses will be undertaken
  • Through participatory research with farming communities, the four paired sets of analogue locations will be fully characterized with regard to crops, soils, climate, current farming practices, roles of male and female farmers, crop diversity, livestock management, farmers’ perceptions of current climate-induced risk and climate change, and possible adaptation strategies. In this context, two PhD students will analyze the particular gender aspects.
  • By means of detailed on-station agronomic- and physiological research, the weather-driven Agricultural Production Systems Simulator (APSIM) will be field-calibrated.
  • Spatial and temporal aspects of climate change will be interpolated through the use of GIS, downscaled global climate model predictions and other innovative tools
  • The potential of improved soil, water and crop management strategies together will be iteratively tested through field research on station and in farmers’ fields as well as simulation based research. This will be contrasted by crops genotypes to mitigate the impacts of increased temperature.
  • Project outputs will be disseminated widely among stakeholders via various on- and offline communication channels.
