The FAO/INFOODS e-Learning Course on Food Composition Data includes an entire unit on biodiversity. It gives an overview on biodiversity and its link to nutrition and agriculture. It sensitizes learners on the fact that the composition of nutrients can be as different among species as among different varieties of the same species. These differences are nutritionally significant and can make the difference between nutritional adequacy and inadequacy. It is therefore important that agriculture takes nutrient composition into account in policy and programmes on breeding and large-scale production. This module is very useful as advocacy material for biodiversity. It also includes case studies relevant for agriculture and nutrition.
