Water as a National Security Flashpoint
Water has long been a
tool of warfare, but in recent years, the world has entered a dark new era of hydroterrorism. Around the globe, from Yemen to Ukraine, this critical resource is increasingly being used as
a tool of control. According to the Pacific
Institute, global
water-related violence surged by more than 50 percent in 2023 alone. Yet,
international institutions still treat water as a development or environmental
issue, rather than as the national security flashpoint it has become.
Fair-weather
frameworks, such as the United Nations’ Water
Convention and
the Integrated
Water Resources Management approach, won’t
survive the coming storms, and as climate shocks intensify, ignoring this
threat is nothing short of negligent. Climate-driven water stress breeds
desperation, especially in places where corrupt or absent governments create a
vacuum. And extremist groups step into this void, offering a distorted sense of
order.

This problem is
particularly pronounced in the Sahel, where violent extremist groups with ties
to the Islamic State
and al Qaeda exploit
water scarcity for power. In areas abandoned by underfunded governments, these
groups offer water and resources to desperate communities, recruiting through a
disturbing fusion of faith and survival.
In my homeland
of Gambia, which is located in the Sahel, rising salinity from
climate change is creeping inland. As a result, nearly a third of the country’s rice fields could become
unusable within a decade. In neighboring Senegal, water demand is projected to surge by up to 60
percent by 2035, while rainfall has generally decreased.

Tensions are already
rising fast. More than a
quarter of Gambia’s 2.6
million people lack access to safe drinking water. Seasonal water shortages
drive internal migration and strain cities such as Banjul. Over the past five
years, there have been 450 clashes between farmers and herders in the central
Sahel, primarily over dwindling water sources and grazing land. Gambia’s
strong tradition of religious tolerance has helped it resist the
allure of extremism thus far. But rising youth
unemployment and climate stress heighten the risk of radicalization.
