 ==Comparing irrigation types==
-Decision making on types of irrigation to use is not always straight forward. Capital cost, water and land scarcity, land tenure, water right security, investment and labor availability must be considered. There are many misconceptions about water use efficiency. Flood irrigation is often maligned as "wasteful" (especially by irrigation system salespeople) when in most cases it uses the least energy and materials of any option, and frequently results in many external ecosystem and downstream benefits, such as recharging aquifers and wells and promoting healthy, perennial streams.   ''See also'' [[Irrigation#Defining efficiency in water usage|Defining efficiency in water usage]] and [[[[Irrigation#In defense of flood irrigation|In defense of flood irrigation]]

+==Defining efficiency in water usage==
 When it comes to irrigation water, efficiency is often thought of as minimizing use of water at all costs. However, in a regenerative agriculture system, the [[definition of efficiency]] must be more [[holistically]] derived. Efficiency in using every available drop of water to grow crops regardless of the cost in energy, capital and labor can be a destructive and non-regenerative task which can ultimately result in destruction of eco-systems (by diversion of rivers or springs or lowering a [[water table]] by pumping for example), pollution and a waste of energy.

 Where labor AND capital are plentiful but water is scarce and there is a great demand for fresh vegetables, places like Israel/Palestine or Arizona for example, it may be worth considering drip irrigation. However even in these situations, energy and materials usage as well as impact to the local ecosystem and financial cost of a proposed agricultural system might mean that it would actually be better to transport vegetables from a region with a lower impact to raising vegetables, or indicate that the local diet and population base is not sustainable in that environment. A holistic cost/benefit analysis of using systems like drip irrigation may produce surprising results to people who assume that those systems are the "most efficient"
