Mozambique’s heavy reliance on water-dependent sectors has created a severe growth constraint, with floods and droughts costing the country an estimated 6.7% of its Gross Domestic Product (GDP) every year.
A new analysis from the Mozambique Water Security Diagnostic reveals that despite the country’s abundant rivers and rainfall, a critical lack of storage infrastructure and weak distribution networks have triggered a state of “economic water scarcity.”
The diagnostic highlights a profound paradox at the center of the nation’s development: while more than half of Mozambique’s gross value added, 84% of jobs, and over 90% of exports depend directly on water-related sectors like agriculture and hydropower, the lack of reliable management is actively choking economic growth and human development.
Vulnerabilities are further compounded by geography, as more than half of the country’s freshwater originates upstream outside its borders, and over 86% of national water storage is concentrated in a single infrastructure asset, the Cahora Bassa dam.
To fully resolve the crisis and transform water systems into drivers of job creation, the diagnostic estimates that Mozambique requires $14.3 billion by 2030 across water supply, sanitation, irrigation, and hydropower.
Economists project that the investment carries an immediate economic dividend, with every dollar invested in water and sanitation adding $0.82 to national GDP, and every $1 million funneled into urban water infrastructure generating $1.2 million in discounted returns.
In response to these findings, Mozambican President Daniel Chapo launched the ProAguas Water Security Compact 2026–2036 on May 19, 2026.
The ten-year compact aims to transition the sector away from fragmented, project-by-project funding toward a sustainable financial model.
Planned reforms include updating raw water tariffs to accurately reflect operational costs, boosting utility creditworthiness, and establishing predictable regulations to secure private capital through public-private partnerships.
