Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims.
About 7.2 million people needed food aid, and 4.4 million people needed help to access water. Food prices have increased a lot due to the drought conditions.

By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under stress conditions. [42] By 2050, more than half of the world's population will live in water-stressed areas, and another billion may lack sufficient water, MIT researchers find. [43]
An improved MPA system would help protect against habitat and ecosystem loss, conserve biological diversity, provide safe breeding grounds for fish and other marine species, improve research opportunities, create a reference point from which the rest of the ocean can be compared against, and may help to re-grow depleted fisheries.
Prior to the 1950s, the general practice was to use hard structures to protect against beach erosion or storm damages. These structures included seawalls and revetments or sand-trapping structures such as groynes. During the 1920s and '30s, private or local community interests protected many coastal areas using these techniques on an ad hoc basis.
