Control And Management

Since water scarcity is an emerging problem in Pakistan; Water Resources Preservation is a matter of substantial importance. When excess water is used for agricultural purposes, it may damage the crops. Manual control and management of water for agricultural purposes take a lot of effort and time. This research work is an effort to propose and implement a fully automated solar irrigation system that may solve the problem of excessive usage of water for agricultural purposes. This proposed system, after sensing various indicators such as wind, temperature, soil, and rain, turns the water motor on and off accordingly and thus ensures calculated and wise usage of water. Moreover, our proposed system has a covering mechanism that covers the model during the rain and when needed.

Freshwater’s transboundary nature (in the form of rivers, lakes, and underground aquifers) means that it ties countries (or riparians) in a web of interdependence. Combined with water scarcity and increased water variability, and the sheer necessity of water for survival and national development, these interdependencies may often lead to conflict. While such conflict is rarely violent in nature, political conflict over water is quite common as states diverge over how to share water or whether to develop a joint river for hydropower, say, or to use the water for agriculture. For the same reasons that water may be a source of conflict, it is also a source of cooperation. In fact, if the number of documented international agreements over shared water resources is any indication, then water’s cooperative history is a rich one. As the most important and accepted tools for formalizing inter-state cooperation, treaties have become the focus of research and analysis. While treaties do not necessarily guarantee cooperation, they do provide states with a platform for dealing with conflict as well as the means to create benefits for sustained cooperation. This also suggests that the way treaties are designed—in other words, what mechanisms and instruments are included in the agreement—is likewise relevant to analyzing conflict and cooperation.

Agriculture And Food

Water availability for agriculture - the major water user worldwide - is one of the most critical factors for food security in many regions of the world. The role of water withdrawals in irrigated agriculture and food security has been receiving substantial attention in recent years. This paper addresses key questions regarding water availability and food security, including: How will water availability and water demand evolve over the next three decades, taking into account availability and variability in water resources, the water supply infrastructure, and irrigation and nonagricultural water demands? What are the relationships among water scarcity, food production, and food security? How much of future food production will come from rainfed and irrigated areas? A global modeling framework, IMPACT-Water, is applied to explore answers to these questions using analysis.
