A treadle pump being demonstrated in Malawi.
A treadle pump is a human-powered Pump designed to lift water from a depth of seven meters or less. A Treadle is a lever device pressed by the foot to drive a machine, in this case a pump. The treadle pump can do most of the work of a motorized pump, but costs considerably less (75%) to purchase. Because it needs no Fossil fuel (it is driven by the operator's body weight and Leg Muscl]s), it can also cost less (50%) to operate than a motorized pump. It can lift five to seven cubic meters of water per hour from wells and Boreholes up to seven meters deep and can also be used to draw water from Lakes and Rivers. Many treadle pumps are manufactured locally, but they can be challenging to produce consistently without highly skilled welders and production hardware.

Compared to bucket irrigation, the treadle pump can greatly increase the income that farmers generate from their land by increasing the number of growing seasons, by expanding the types of crops that can be cultivated, and improving on the quality of grown crops.

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, and/or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture.

Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).

Sustainable agriculture is the practice of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will last over the long term: satisfy human food and fiber needs; make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls; sustain the economic viability of farm operations; and enhance the quality of life for farmers and society as a whole.”
