Black et al. Lancet 2008
NUTRITION FOR DEVELOPMENT Strong evidence that adequate nutrition in utero and in the first 2 years of life is essential for formation of human capital. Growth and development Disease and survival Long-term implications of under-nutrition adult human capital, height, school achievement, economic productivity and birth-weight of the offspring.
NUTRITION FOR DEVELOPMENT Underweight populations are more prone to negative effects of overweight and the adoption of diets and lifestyles of developed countries. Earlier and more type II diabetes More cardio-vascular risk More pronounced effects of obesity
CHALLENGE 1: SUPPORTING RELEVANT RESEARCH 99 % grants for “new solutions” that can reduce mortality by 22% 1 % for solutions that increase coverage that can reduce mortality by 66 % Leroy et al. American Journal of Public Health 2007

GEPHI –NUTRITIONAL STATUS
Publication analysis conclusions A lot of research is done Little cross border networking within the continent Duplication of research Lack of evidence base in general Evidence development does not address the “how can we improve the situation” rather quick fixes 10
CHALLENGE 2: PROVIDE A HEALTHY DIET IN A SUSTAINABLE WAY Population increase to 9-10 billion by 2050 70 % of arable land is used for animal production Food speculation Cereals or land for bio-fuel Water export Climatic changes and local stresses
A NEW FOCUS ON RESEARCH FOR DECISION MAKING Sustainability a key element Develop mechanisms to identify research questions from an African policy perspective. Knowledge centres Training of experts Create an African research fund to support evidence based decision making research
