Food and Water
Back to Energy.
Food and water are essential to human life, though agriculture is the leading human land use. We present key data on world dietary needs and options, and the land, energy, emissions, and water impacts of meeting those needs. We also consider the potential impacts of agricultural practices, such as organic farming, biotechnology, aquaculture, and intensive options such as greenhouses on overall impacts. We also show the main uses of water and options for providing and treating water.
