Pakistan pins big hopes on small dams to help farmers beat drought

Colorado is only now recovering from a 16-year long drought that resulted in the aquifer irrigation system becoming increasingly dry. Until the farmers decided to tax themselves for water consumption, realizing that saving water now and taxing themselves would protect their farms and livelihood in the long run.

Environmental refugees in Ethiopia flee their country because there are no jobs without healthy land. A group of former refugees have returned to Ethiopia with a business venture in Gergera to improve the land by regreening efforts, foresting, and building water conservation systems. The new businesses demonstrated such positive effects that the region is now on the brink of resettlement due to improved environmental conditions.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.

In the arid Karnataka region of India, millet is largely replacing rice as a staple crop. Not only does this drought-resistant grain require far less water and pesticide, but it's also highly nutritious. Perceptions are also beginning to change. What was once viewed as subpar food is starting to look like a winner in an increasingly thirsty world.

The Utah state government is offering grants to encourage and enable farmers to invest in water-saving technology amid a severe drought. A farmer who wants to install a better irrigation system, like drip irrigation, will pay for half of the upgrade and the state will pay for the other half.

Communities in Siaya are excavating water pans to store runoff from the rainy season for agricultural and household use during droughts. The pans are dug in clay soil, and their size and depth are determined based on community needs.

A greenhouse that is cooled by seawater and the wind is allowing farmers in Somaliland to grow crops like tomatoes and vegetables despite extreme heat. By creating an environment that is higher in humidity and cooler in temperature, plants don’t need to drink as much water — almost 10 times less water because of the cooling system. There are challenges to scaling the response, but these greenhouses offer farmers the potential to increase their revenue in Africa.

Israel experienced extreme drought a few years ago and its water supply was very low. National campaigns to install desalination plants have helped Israel turnaround its inadequate water supply into a surplus. The water scientists who have helped make this surplus see an opportunity for water diplomacy and the de-politicization of water in the Middle East so that more of it can be shared with other geographies.

The U.S. government has developed different sensors for irrigation devices that gauge water demand and help conserve use. as water shortages caused by drought have increased across the globe, and farmers are faced with economic burdens, such technology is focusin on sustainability for the future.

In the face of a prolonged drought, residents of Melbourne, Australia, cut water consumption in half by capturing rainwater and using efficient toilets and washing machines.
