This report multi-purpose sweet sorghum varieties with high grain agricultural environment impacted by the consequences contains articles covering the major advancements that yield and stover quality for integrating crop and livestock of a changing climate cannot be overestimated as the we experienced during the year with regards to crop systems in West and Central Africa (WCA). Also for the impacts of global climate change – combined with rapid improvement, integrated crop management and systems first time, we present the results of our preliminary socioeconomic changes – are likely to increase uncertainty generations upcoming science for Future-proof analysis, policy and impact. experiences with the development of near-infrared in water availability and water security. In this context, reflectance spectroscopic (NIRS) calibrations for assessing we are carrying out research on current and future water | sorghum stem quality as a determinant of fodder and feed availability and on the demand scenarios. quality for livestock. Our research is geared towards improving water Our participatory variety selection by farmers at multiple resources management and addressing water-related 2015 Highlights locations has provided interesting results that are problems in the region. We are committed to generating highlighted in the report. You will learn more about and exchanging knowledge in order to strengthen efforts of scientists and producers in designing effective cooperation, and we hope that our combined efforts groundnut breeding strategies through farmer-breeder will improve water management and help address the interactions in Northern Nigeria.
