Issues in Brief

Human Health and Nutrition
Good health is fundamental to living a productive life, meeting basic needs and contributing to community life. Good health is an enabling condition for the development of human potential.

Linkages between agriculture andhealth. Source: Hawkes and Ruel, 2006. The components of health are multiple and their interactions complex. The health of an individual is strongly influenced by genetic make-up, nutritional status, access to health care, socioeconomic status, relationships with family members, participation in community life, personal habits and lifestyle choices. The environment – natural, climatic, physical,social or workplace – can also play a major role in determining the health of individuals. Agricultural knowledge, science and technology (AKST) can play an important role in improving human health and nutrition. Although current global production of food calories is sufficient to feed the world’s population today, millions die or are debilitated every year by hunger and malnutrition, making themvulnerable to infectious diseases, e.g., HIV/AIDS, malaria, tuberculosis, and diarrheal diseases. In many developing countries, hunger and health risks are exacerbated by extreme poverty and poor and dangerous working conditions. About 50% of the health burden of malnutrition is attributable to unsafe water, unimproved sanitation and hygiene. In contrast, in industrialized countries, over-nutrition andfood safety issues, including foodborne illnesses affecting human health as well as impacts associated with agricultural production systems, are predominant concerns. There is also a significant incidence of undernutrition among the poor, and a higher burden of both infectious and non-communicable diseases associated with metabolic syndromes, such as diabetes and obesity.

AKST has an important role to play in both developing and industrialized countries in contributing to food security and food sovereignty, and breaking the malnutrition/poor health/low productivity cycle.
