If GHG and water prices are not embedded in the production process, irrigation is more profitable per hectare.
Water productivity and benefit cost ratio analysis show that vegetables and fruit production were more profitable than rice cultivation under irrigation with harvested rainwater.
Additionally, SoG's reduced water efficiency leads to irrigation becoming less profitable, compounding the pressures on the agriculture sector and leading to greater areal expansion of agriculture (and concurrent reduction in VAFOOD).
Substituting rice with ZT maize was equally profitable but with 88 95% less irrigation water use.
Thus, there is a need to promote profitable yet safe practices to continue benefiting from sewage irrigation.
"Military activities that destroy infrastructure such as irrigation and roads therefore make opium relatively more profitable".
In addition, the show says, "most irrigation dams deliver less water and are less profitable than expected".
A tradeoff occurs between the volume of the aquifer and economic returns due to groundwater withdrawal for irrigation, but the farm's ability to grow profitable lower irrigation crops dampens the intensity of this tradeoff.
After all, between 1862 and 1934, the Homestead Act transferred 10 percent of all land in the United States from federal to private control, and it's federal money that pays for much of the roads and irrigation systems that make farming in the valley so profitable.
As it should, says pure economics: farming in such areas is far less productive and less profitable (even were water priced realistically) than the intensive, year-round irrigation-based growing of flowers, fruit and vegetables in dry but sunny Almeria, in the far south.
