This document discusses assessing nutritional status and vulnerability at global, national, and local levels. It outlines how anthropometric measurements are used to evaluate nutritional status, especially for children, women, and adults. Key indicators like underweight, stunting, and wasting are defined. Large-scale surveys conducted by international organizations help assess nutrition, health, and living standards. Repeated small-scale surveys and participatory methods also monitor improvements. Identifying vulnerable groups and factors contributing to food insecurity helps design targeted nutrition programs. Options presented include improving livelihoods through credit, irrigation, agriculture, livestock, and ecotourism.
