Improved water, energy, and food security on a global level can be achieved through a nexus approach [17] —an approach that integrates management and governance across sectors and scales. [18] A nexus approach can support the transition to a green economy, which aims, among other things, at resource use efficiency and greater policy coherence ...
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

Its formal name was "High-Level Conference on World Food Security: the Challenges of Climate Change and Bioenergy". The Conference followed Expert Meetings and Stakeholder Consultations held by the FAO between January and April 2008. [1] The conference focused on the world food price crisis, climate change and agriculture and food vs fuel issues
Similarly, household food security is considered to exist when all the members of a family, at all times, have access to enough food for an active, healthy life. [1] Individuals who are food-secure do not live in hunger or fear of starvation. [2] Food security includes resilience to future disruptions of food supply.
The term food security was first used in the 1960-1970s to refer to food supply and consistent access to food in international development work. [13] In 1966 the treaty titled the United Nations International Covenant on Economic, Social and Cultural Rights was created to ensure economic, social and cultural rights including the “inalienable right to adequate nutritious food”.

Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called ...
The FAO concludes that nearly 30 percent of all available agricultural land in the world – 1.4 billion hectares – is used for produced but uneaten food. The global blue water footprint of food waste is 250 km 3, the amount of water that flows annually through the Volga or three times Lake Geneva. [200]
