The water, energy and food security nexus means that the three sectors — water security, energy security and food security — are inextricably linked and that actions in one area more often than not have impacts in one or both of the others. These linkages have always been present, but as the world population hurtles towards 8 billion with increasing demands for basic services and growing desires for higher living standards, the need for more conscious stewardship of the vital resources required to achieve those services and desires has become both more obvious and urgent. == Definitions== *Water security is defined in the Millennium Development Goals (MDGs) as "access to safe drinking water and sanitation",〔(UNDP: Millennium Development Goals, Goal 7: Ensure environmental sustainability )〕 both of which have recently become a human right. While not part of most water security definitions yet, availability of and access to water for other human and ecosystem uses is also very important from a nexus perspective. *Energy security has been defined as "access to clean, reliable and affordable energy services for cooking and heating, lighting, communications and productive uses" (United Nations),〔(UN Secretary General’s Advisory Group on Energy and Climate Change (AGECC), Summary Report and Recommendations, 28 April 2010, p. 13 )〕 and as "uninterrupted physical availability (energy ) at a price which is affordable, while respecting environment concerns". *Food security is defined by the Food and Agricultural Organization (FAO) as "availability and access to sufficient, safe and nutritious food to meet the dietary needs and food preferences for an active and healthy life".〔(FAO. 1996. Rome Declaration on World Food Security and World Food Summit Plan of Action. World Food Summit 13–17 November 1996. Rome. )〕 Adequate food has also been defined as a human right. The emphasis on access in these definitions also implies that security is not so much about average (e.g., annual) availability of resources; it has to encompass variability and extreme situations such as droughts or price shocks, and the resilience of the poor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Water, energy and food security nexus」の詳細全文を読む スポンサード リンク
