Changes in water resources availability can be expected as consequences of climate change, population growth, economic development and environmental considerations. Water resource systems have benefited both people and their economies for many centuries. The services provided by such systems are multiple. Yet in many regions especially Middle East and North Africa (MENA) regions, water resource systems are not able to meet the demands, or even the basic needs, for clean fresh water, nor can they support and maintain resilient biodiverse ecosystems.It is considered that the adoption of IWRM concept could be the only possible way to maximize the benefit of Water resources in a sustainable manner without compromising the quality of the environmental system, which in turn will require construction of regulation and control structures on the rivers and streams in a planned and integrated manner. Hence, MENA region countries are following the principles of Integrated Water Resources Management (IWRM). This letter evaluates the current IWRM system of MENA region and highlights different challenges that the countries are facing while applying IWRM such as competition of water use, water scarcity, community conflict and unemployment.IntroductionMENA communities face many challenges with respect to their water needs. These challenges include increased water scarcity and flooding associated with climate variability, economic, uncertainty, a complex web of regulation and bureaucracy, aging and disregarding infrastructure, pollution and impaired water resources and a broad range of stakeholders with poor understanding of water issues. The objective of this letter is to create a plate form for MEENA communities to overcome these challenges through organizing around and operating under key sustainability principles and practices. Water resources are being altered due to changes in climate, population, economic development and environmental considerations. The Middle East and North Africa (MENA) region can be considered as the most water-scarce region of the world. Moreover, water availability is highly variable within the MENA region. For example, within MENA the per capita water availability is currently less than 200 m3 per year in Yemen and Jordan. The 4th Assessment Report of the IPCC (IPCC, 2007) projects shows strong changes in climate across the MENA region. Temperatures are expected to increase while at the same time substantial decreases in precipitation are projected. These elevated temperatures will result in higher evapotranspiration demands and this will, in combination with decreases in precipitation, severely stress the water resources in the region. ? Statement of ProblemMENA countries are suffering from a huge deficit in their water resources reaching more than 20 billion cubic meters, being met mainly by an intensive over-drafting of renewable and non-renewable groundwater resources and rivers for their different uses. Furthermore, the conflict between the agricultural and domestic sectors on the limited water resources in the region are rising, and as a result, groundwater overexploitation and mining is expected to continue to meet growing demand in these two sectors.Some of the challenges for adopting the concept in MENA are as follows:1. Scarcity.2. Water security.3. Community conflict.4. Limitation of water resources and increasing water scarcity with the time due to prevailing aridity, fast population growth and agricultural policies. 5. Inferior quality of water services in large cities due to fast pace of urbanization If the current population growth rates, water management approach, water use practices and patterns continue, annual demand may reach more then as its now. As a result, the food security will become a challenge. In addition, the shortage of water will also severely affected irrigation, drinking and other daily water uses the water shortage occurred especially in dry regions because of urbanization and rapid increase in population. On the other hand, the climate change is another factor that challenges the availability of limited resources.Expected Outcomes:Studies show that creating an IWRM plan is more efficient from generating customary water supply plan. Unlike traditional water plan development, an IWRM strategy requires thinking about water in the context of economic, social and environmental needs and creating an adaptable framework for ongoing action and coordination instead of a static project-oriented plan.  To accomplish this, it is imperative to include the public and all sectors affected by water planning.  Developing water management policy can also help us to find other innovative and technical approaches to identify threats to water resources both in quantity and quality. And design legal and planning instruments to deal with each threat and it can also assist us to provide legal, technical, and administrative guidelines for mechanisms to ensure efficient allocation of water, and providing a strategy for implementation, monitoring and enforcement major water-related projects. This will be helpful to increase the agricultural based livelihood, improve irrigation facilities, and find the solution for uncontrolled water loss to stabilize crop production using watershed as one of the essential variants to accomplish the objectives and electricity production and other economic production. It will nourish the agriculture sector in a sustainable manner as a strategic and critical pillar for region’s economic growth. But still, the main question remains: How to develop new scientific tools, concepts and theories to solve the water loss management problems in MENA region?? Conclusion Effective utilization of the water resources optimizes the benefit of the water resources, but it is the biggest challenge for the MENA countries. It is considered that the adoption of IWRM concept could be the only way to maximize the benefit of Water resources in a sustainable manner. The present MENA region water laws have also envisaged adoption of IWRM concept.
