People, Land and Food Production - Potentials in the Developing World

Understanding the nature and dimension of the land and water resources available for food and agriculture development, and the policies available to develop them, have been among the focal points of the work of the Land and Water Development Division of the Food and Agricultural Organization of the United Nations and of the Food and Agriculture Program at the International Institute for Applied Systems Analysis. As we anticipate, over the coming decades, a technological transformation of agriculture which will be constrained by resource limitations and which could have environmental consequences, a number of important questions arise: (a) What is the stable, sustainable production potential of the world? of regions? of nations? (b) How does this production potential in specific areas (within countries and groups of countries) compare to the food requirements of the future populations of these areas? (c) What alternative transition paths are available to reach desirable levels of this production potential? (d) What are the sustainable and efficient combinations of techniques of food production? (e) What are the input requirements of such techniques? (f) What are the policy implications at national, regional and global levels of sustainability? Stability and sustainability are both desirable properties of agricultural land resources development. We hold ecological considerations to be of critical importance in answering the questions posed above. This paper presents the results of a recent study entitled "Land Resources for the Populations of the Future" carried out by the Food and Agriculture Organization of the United Nations in collaboration with the Food and Agriculture Program of IIASA with financial support from the United Nations Fund for Population Activities. The study was designed to quantify potential population supporting capacities of land resources in the developing regions of the world, based on ecological and technological limits to food production. An understanding of these limits is critical to agricultural policy formulation and development planning. This paper highlights policy implications for developing countries

Food and Nutrition Security Indicators: A Review

In this paper, we review existing food and nutrition security indicators, discuss some of their advantages and disadvantages, and finally classify them and describe their relationships and overlaps. In order to achieve this, the paper makes reference to the existing definitions of food and nutrition security (FNS), in particular as they have been agreed upon and implemented in the FoodSecure project (www.foodsecure.eu). The main existing conceptual frameworks of FNS predating the present paper are also used as guidelines and briefly discussed. Finally, we make recommendations in terms of the most appropriate FNS indicators to quantify the impacts of various shocks and interventions on food and nutrition security outcomes
