This report outlines strategies to address water scarcity, improve access to clean water, and ensure sustainable management of this vital resource. Over two billion people live in countries where water supply is inadequate. Half of the world's population could be living in areas facing water scarcity by as early as 2025. Some 700 million people could be displaced by intense water scarcity by 2030.Agriculture uses 70% of the world's accessible freshwater, but some 60% of this is wasted due to leaky irrigation systems, inefficient application methods as well as the cultivation of crops that are too thirsty for the environment in which they are grown. But people need to eat good food

3. 2050: Global water security and sustainability.
Conclusion: The global water crisis requires immediate attention and collective action. Implementing these solutions will ensure a water-secure future for generations to come.
Boreholes are bringing up air, not water’
Freshwater is a vital resource for both ecosystem health and human survival, and it is the natural resource that is the most extracted at the global level. Excessive freshwater consumption can be responsible for a scarcity in the circulation rate, which occurs when the freshwater demand exceeds its availability. Hence, water consumption needs to be optimised in all human activities, given the increasing freshwater scarcity due to climate changes and to the annual net increase in the human population of 81,000,000. Freshwater plays many important roles in daily life for example, agriculture is responsible for nearly 70% of that withdrawal volume, and it is therefore, the most water-intensive sector. This puts emphasis upon the urgent need of transitioning towards more sustainable agricultural and food-production/consumption systems. Water Footprint (WF) is increasingly playing a guiding role in that context. Indeed, it makes it possible to quantify water consumption and related environmental consequences. With the objective of contributing to enhancement of research and of supporting practitioners and decision-makers in environmentally sustainable and resilient food production/consumption, the authors of this article addressed the relevant issues connected with: a) physical and economic water scarcity in agriculture, b) practices and tools to reduce water wastage, c) WF assessment methodologies. A number of environmental, economic, and engineering solutions were proposed to mitigate water scarcity. The improvement of irrigation technologies and practices was identified as an important major way to reduce water scarcity. Additionally, solar powered ‘reverse-osmosis’ is being used in many parts of the world to produce irrigation water from saline water, thereby reducing the need to extract freshwater from underground aquifers. This article confirmed the importance of research on water scarcity; moreover, it can stimulate development and application of solutions that make agricultural production/consumption more efficient and resilient.
The world is facing a water crisis that threatens the lives of billions of people, the health of ecosystems, and the world's food supply:
Water scarcity
Only 3% of the world's water is fresh, and two-thirds of that is frozen in glaciers. Around 1.1 billion people lack access to water, and 2.7 billion experience water scarcity for at least a month each year.
Contaminated water
1.2 billion people drink water that is contaminated with feces, and many more drink water that is not adequately protected from sanitary hazards.
Inadequate sanitation
2 billion people lack access to basic sanitation facilities, and 2.4 billion people are exposed to water-borne diseases.
Climate change is causing droughts, floods, and more frequent and higher water temperatures, which can exacerbate water pollution.
Population growth
Population growth and economic development are expected to worsen water stress.
Agriculture
Agriculture consumes more water than any other source, and much of that water is wasted.
Some solutions to the water crisis include:
Capturing rainwater
Adopting climate-smart agriculture
Reusing wastewater
Exploring, protecting, and sustainably using groundwater
Burgeoning populations mean there may be a 40% shortfall between forecast demand and available supply of water by 2030. Looking ahead to 2050, it is projected that as many as 3.2 billion people will live in areas with severe water scarcity.
About a third of the world’s population already deals with water stress, or limited access to clean water. And in a few years, it is believed that number will increase to two-thirds of the world population being placed under these conditions.
Unfortunately, that means there are currently over a billion people affected by water scarcity, water stress, or other unsafe water delivery conditions.
Currently, areas in southern and eastern Africa have the least access to clean water. Countries in Asia such as India, China, and Pakistan all deal with exponential population growth while experiencing record low amounts of groundwater. More places than ever are dealing with harsher weather conditions affecting the water supply and high urban water demand, resulting in more calls for regulations.
Whatever the cause of water scarcity, it often ties back to higher demand from overpopulation. Here are a few correlating factors of overpopulation’s effect on water scarcity.
