Water footprint is a metric that quantifies the amount of water used to produce each of the goods and services we use. It allows these goods and services to be compared in terms of their water impact, and so to the impact on limited water resources of consumption by individuals, organisations, and even nation states. Water footprints incorporate all the water used – i.e. unable to be used again due to evaporation or removal in products – across the full lifecycle of a produce from production through to consumption, including all inputs to production (e.g. feed crops used in pork production). It has three components: (1) green water - rainwater used in soils; (2) blue water - freshwater sources; (3) grey water - water amount needed to dilute pollution to safe levels.

The World Health Assembly is the forum through which the World Health Organisation is governed.

Wildlife-friendly farming, while a fairly informal term, generally refers to an approach to farming that aims to support both food production and the conservation of biodiversity on farmland. Wildlife-friendly farming is associated with the use of reduced chemical and fertiliser inputs and the preservation of native vegetation (e.g. flowers, trees, and bushes) on or around farmland. Those who use the term tend to equate wildlife-friendly farming with a land sharing approach. Related although not synonymous terms include organic farming and agroecology.

The World Health Organisation (WHO) is a specialised branch of the United Nations. It is dedicated to improving public health worldwide.

An international organisation that regulates and facilitates global trade. Its membership (and the source of its operating budget) includes 164 countries, which comprise the parties in the vast majority of global trading relationships. Its goals are broadly to reduce barriers to trade such as tariffs and to ensure that trade occurs in a transparent, rule-governed system. It is simultaneously seen by some as an important vehicle for decreasing global economic inequality by encouraging free trade, and by others as an important contributor to global economic inequality by facilitating exploitative practices and the continued flow of capital into wealthy countries.
