Water and Peace

The issue explained

Water is under growing pressure. The water-related impacts of climate change are worsening and a growing global population is placing increasing demand on a finite resource. Within many countries, people’s access to safe drinking water is unevenly and unfairly distributed. Between countries, the widespread lack of transboundary cooperation on shared water resources poses a risk to the quality and quantity of water supplies and therefore threatens social and international stability.

Poor provision of water services can delegitimize States. The inability of a government to provide basic water services can lead to a delegitimization of State institutions and ignite social unrest, especially in the context of food insecurity, high unemployment and internal migration.

Water often plays a role in conflict:

1. Water can be a trigger when interests of different water users, including States and provinces, clash and are perceived as irreconcilable, or when water quantity and/or quality decreases, which may affect human- and ecosystem health.
2. Water can be a weapon during armed conflict – used by both State and non-State actors – as a means to gain or maintain control over territory and populations or as a means to pressurize opponent groups. 
3. Water can be a casualty of conflict when water resources, water systems or utility employees are intentional or incidental casualties or targets of violence. Attacks on civilian infrastructure, including water systems, pose serious health risks and violate international humanitarian law.

The way forward

Water can be a tool for peace. Over time, there have been many more incidences of cooperation than conflict over water, but there is much more to do. Peaceful cooperation around water – within and between countries – can pave the way for peaceful cooperation in all sectors. 

Water can be a stabilizing force and a catalyst for sustainable development. We must act upon the realization that water is not only a resource to be used and competed over – it is a human right, intrinsic to every aspect of life.

• At the local and national level, different water users – particularly water and sanitation utilities, energy, food and industry – must cooperate through an integrated water resources management approach and promote a circular economy that fulfils people’s human rights.
• At the basin level, countries should develop agreements and set up institutions to peacefully manage water resources that cross international borders.
• Governments should cooperate on transboundary waters bilaterally, regionally or globally, for example through signing up to and implementing the United Nations Water Convention and Watercourses Convention. 

Water cooperation creates a positive ripple effect. Working together on water across borders and sectors will accelerate progress across the Sustainable Development Goals, enhancing food security, sustaining healthy livelihoods and ecosystems, helping to build resilience to climate change, contributing to disaster risk reduction, providing renewable energy, supporting cities and industry, and fostering regional integration and peace.

• Financing transboundary water cooperation poses several challenges due to a perception that such projects are high risk, or because the associated benefits are not well understood. (UNECE, 2021)
   
• Water cooperation across borders and sectors generates many benefits including enhancing food security, sustaining healthy livelihoods and ecosystems, helping to address resilience to climate change, contributing to disaster risk reduction, providing renewable energy, supporting cities and industry, and fostering regional integration and peace. (UNESCO/UNECE, 2023)
   
• Roughly half of the world’s population is experiencing severe water scarcity for at least part of the year. (IPCC, 2022) These numbers are expected to increase, exacerbated by climate change and population growth. (WMO, 2022)
   
• Only 0.5% of water on Earth is useable and available freshwater – and climate change is dangerously affecting that supply. Over the past twenty years, terrestrial water storage – including soil moisture, snow and ice – has dropped at a rate of 1 cm per year, with major ramifications for water security. (WMO, 2021)
   
• Climate change, population growth and increasing water scarcity will put pressure on food supply (IPCC, 2014)  as most of the freshwater used, about 72% on average, is used for agriculture. (UN-Water, 2023)
   
• Children under the age of 15 living in countries affected by protracted conflict are, on average, almost three times more likely to die from diarrhoeal diseases caused by a lack of safe water, sanitation and hygiene than by direct violence. (UNICEF, 2019)
   
• Transboundary waters account for 60 per cent of the world’s freshwater flows, and 153 countries have territory within at least 1 of the 310 transboundary river and lake basins and inventoried 468 transboundary aquifer systems. (UN-Water, 2023)
