Around 2400 BCE, the Sumerian city-states of Lagash and Umma went to war over irrigation water. Lagash diverted canals feeding Umma’s fields, sparking one of the first documented conflicts over a resource humanity cannot live without. More than four millennia later, the same struggle endures-only now, it shapes geopolitics.
Afghanistan’s Qosh Tepa Canal is the newest chapter in this old story. The 285-kilometer waterway cuts across northern Afghanistan, diverting the Amu Darya River, which sustains millions in Uzbekistan and Turkmenistan. When complete, it could redirect up to 30 percent of the river’s annual flow-roughly six to 13 billion cubic meters of water. More than 230 kilometers were completed by March 2025, with full operation expected by 2028. For Afghanistan, long scarred by war and sanctions, the canal promises food security and sovereignty-a bold bid to trade dependency for self-reliance.
Downstream, the picture darkens. Uzbekistan and Turkmenistan rely heavily on the Amu Darya to irrigate their cotton and wheat fields. Reduced flow could devastate harvests, worsen soil salinization, and accelerate the ecological ruin of the basin.
The region has already lived through one water catastrophe- the Aral Sea’s collapse in the 1960s during the Soviet Union’s large-scale irrigation projects, a stark reminder of what happens when politics outrun planning. The worst-case projections estimate Uzbekistan could lose up to 15 percent of its water supply and Turkmenistan as much as 80 percent, with dire economic and political consequences.
The deeper issue is governance. Afghanistan is not a party to the 1996 Almaty Agreement regulating Central Asian water use and has no treaty with its northern neighbors. That absence leaves Kabul acting unilaterally, without mechanisms for data sharing or accountability. Sovereignty without coordination risks turning necessity into conflict.
Such tensions echo globally. Ethiopia’s Grand Renaissance Dam continues to test Egypt’s historic rights to the Nile. Turkey’s control of the Tigris and Euphrates strains its ties with Iraq and Syria. Even the Indus Waters Treaty between India and Pakistan-one of the world’s most durable water-sharing agreements-exists in a constant state of political tension. Across continents, rivers remain the front lines of power. Global food markets, energy flows, and trade routes are all influenced by water access. When upstream nations divert rivers, downstream economies falter, and global prices surge.
Afghanistan’s canal now draws attention far beyond Central Asia. Russia sees it as a challenge to its regional influence. China worries about instability along its Belt and Road corridors. Iran views it as a precedent for unilateral control. What appears to be a national development project has become a geopolitical signal-an assertion that Afghanistan will act first and negotiate later.
For the Philippines, this may seem remote, yet the same logic applies. Our water disputes unfold within our borders-between provinces, agencies, and sectors rather than nations. The 2019 Metro Manila water crisis left six million residents with intermittent supply and P464 million in crop losses. In Mindanao, drought and poor irrigation have displaced families and deepened rural poverty.
Senator Grace Poe noted that at least 45 executive agencies across 15 departments share overlapping water mandates. This fragmentation has left the Philippines ranked 33rd of 48 Asian countries in water security, despite its strong economic growth. Watershed management is divided, enforcement inconsistent, and long-term planning scarce. The proposed Department of Water Resources bill-House Bill 9663 and Senate Bill 2771-aims to centralize authority, but as of late 2024, it remains stalled in Congress.
Agriculture, which employs about 20 percent of the national workforce, depends on irrigation systems that lose nearly half their supply to inefficiency. Each drought turns the country from a rice producer into an importer, pushing food prices and inflation higher. The National Economic and Development Authority has warned that water scarcity threatens sustained growth as severely as any energy or fiscal crisis.
Water is not merely a natural resource. It is the foundation of power and survival and the first test of a nation’s competence. It is more than nature’s gift; it is the measure of how societies endure.
The Qosh Tepa Canal underscores a truth as old as Mesopotamia: whoever controls the flow controls the future. The Philippines, surrounded by water yet increasingly short of it, must stop treating scarcity as a temporary inconvenience. Nations that manage water with foresight will endure. Those that do not will discover, too late, that neglect is the most dangerous current of all.
