Challenges and Opportunities for Agricultural Intensification of the Humid Highland Systems of Sub-Saharan Africa

The humid highlands in sub-Saharan Africa (SSA) are characterized by high population densities and require intensification. The Consortium for Improving Agriculture-based Livelihoods in Central Africa (CIALCA) has set up a research for development platform in various mandate areas in DR Congo, Burundi, and Rwanda, aiming to identify improved production, market, and nutrition options and facilitating the access for development partners to these options. This platform is supported by capacity building, multi-stakeholder dialogue, and monitoring and evaluation efforts. The conference, facilitated by CIALCA, aimed to (i) take stock of the state-of the art in agricultural intensification in the highlands of SSA and (ii) chart the way forward for agricultural research for development in the humid highlands of SSA, and more specifically in the recently launched Humidtropics Consortium Research Programme, through keynote, oral and poster presentations, and strategic panel discussions.

Bernard Vanlauwe joined IITA in Kenya in March 2012 to lead the Central Africa hub and the Natural Resource Management research area. In this capacity, he is also having an oversight role in the Consortium Research Programs (CRP) on Humidtropics; the Water, Land, and Ecosystems; and CCAFS. Prior to this appointment, he was the leader of the Integrated Soil Fertility Management (ISFM) program of the Tropical Soil Biology and Fertility research area of CIAT (TSBF). He joined CIAT-TSBF in 2001 and led the development, adaptation, and dissemination of best ISFM options in various agro ecological zones in sub-Saharan Africa. In September 2010, he obtained a Visiting Professor position at the Swedish Agricultural University in Uppsala in the Soils and Environment Department. He had also worked at IITA in Nigeria (1991 2000) and the Catholic University of Leuven, Belgium (1989-1991), focusing on unraveling the mechanisms underlying nutrient and soil organic matter dynamics in tropical agroecosystems. In that context, he obtained his PhD in 1996 in Applied Biological Sciences. He has published over 100 papers in scientific journals and over 120 in other forms and has (co-) supervised over 30 MSc and 10 PhD students.
