Water footprints

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.

Wildlife-friendly farming

while this is a fairly informal term, it 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.
