Rope pump upper construction
Rope pumps. Industrial hand pumps, such as the Indian Mark II, for communal wells donated by development projects often break down after two years. If maintenance costs are the responsibility of the users, then this cost is too high when repairs prove necessary and the pump is left nonfunctional.

An alternative reliable hand pump is needed for communal and private use to supply clean drinking water and irrigation. These pumps will raise the standard of living if they are low cost, reliable and pump water effectively. Efficiency is critical to irrigate a garden in the dry season due to the relatively large amount of water involved. Such gardens provide food and increased income.

Local affordability, maintenance and good pump efficiency are required features. Local affordability means a twenty-to-hundred-fold cost reduction compared to imported industrial goods. Local maintenance is only possible when made with local resources and skills.

A global tipping point will be reached in 10 years [ 2016 ] if levels of greenhouse gases like methane and CO2 are not reduced. Global warming at this point becomes unstoppable.

A windmill is used to power a water pump which fills a swimming pool.
Appropriate technology (AT) is technology that is designed with special consideration to the context of its use - including environmental, ethical, cultural, social, political, and economical aspects of the community it is intended for. With these goals in mind, AT proponents claim their methods require fewer resources, are easier to maintain, and have less of an impact on the environment compared to techniques from mainstream technology, which they contend is wasteful and environmentally polluting.

The term is usually used to describe simple technologies proponents consider suitable for use in developing nations or less developed rural areas of industrialized nations. This form of "appropriate technology" usually prefers labor-intensive solutions over capital-intensive ones, although labor-saving devices are also used where this does not mean high capital or maintenance cost. In practice, appropriate technology is often something described as using the simplest level of technology that can effectively achieve the intended purpose in a particular location. In industrialized nations, the term appropriate technology takes a different meaning, often referring to engineering that takes special consideration of its social and environmental ramifications.
