The source of the Nile is in the Nyungwe Forest in Rwanda. From there, it travels northwards for 6,718km, making it the longest river in the world

The total long-term annual renewable water resources are estimated at 120BCM, of which about 78BCM go to surface run-off, and groundwater recharge is estimated at about 42BCM per annum, 11BCM by qanats (underground water supply systems) and springs, plus 31BCM by wells.

Water supply and food security will pose a major challenge in the coming years, which many government officials refer to as a human security issue. Both the country’s natural climatic situation and the government policies in managing its limited water resources over the past few decades have exacerbated this challenge.

Bilateral and tripartite meetings have taken place between Turkey, Iraq and Syria since the mid-1960s. Despite the various attempts to negotiate a water-sharing agreement, the three riparians have disagreed on the division of water quantities and embarked upon individual water sector projects.

The Ministry of Water Resources has shown that it understands the challenges that face the country and has adopted a strategy that will help alleviate water scarcity in the future. Despite this, several crises threaten to push the country towards further deterioration. Failing infrastructure, outdated agricultural and irrigation systems, upstream development, the IS insurgency, budget shortfalls, political instability and climate change all require discreet solutions, any one of which is difficult on its own let alone in tandem.

Internationally, a water availability below 1,000 m3 per person per year is defined as water scarcity, while below 500 m3 is considered “absolute scarcity”. Jordan’s lack of water resources impacts the country’s economic growth, political stability and national security, but also public health.

Groundwater and surface water account for respectively 51% and 49% of total water supply in Lebanon. Most of the surface water supply originates from spring sources, with 637 MCM/yr currently exploited.

In 2012, the Water Authority published a master plan outlining a strategy to ensure water availability until 2050. While total water use is expected to rise from 2,131 MCM in 2010 to 3,571 MCM in 2050

Lebanon has 40 rivers of which 17 are considered perennial. The total combined annual river flow is estimated at around 3,900 million cubic metres (MCM), with most of the flow (75%) occurring from January to May.

Treating wastewater will eliminate environmental degradation, improve public health and increase water availability, as the treated water will be reused for agriculture. The PWA has conducted several studies on building new treatment plants and rehabilitating existing ones throughout the West Bank with the support of international donors. In its strategy published in 2014, the PWA states that three new wastewater treatment plants are under reconstruction, and six feasibility studies have been conducted for constructing additional treatment plants.
