Global Study Reveals Critical Sustainability Gaps in Transboundary River Basins
TL;DR
Countries can gain strategic advantages by leading coordinated efforts on clean water, economic growth, and health in transboundary basins to boost sustainability scores and regional influence.
Researchers integrated Environmental Gini coefficients with 98 SDG indicators to assess 310 transboundary basins, identifying four challenge types and modeling multi-goal intervention strategies.
Coordinated action on water, economy, and health could help 38% of shared river basins achieve sustainability, reducing inequality and improving lives for billions worldwide.
A global study reveals transboundary rivers score just 42/100 on sustainability, with African basins as low as 13, while European rivers exceed 75.

A new global assessment reveals that transboundary river basins, which support billions of people across national borders, are significantly underperforming in sustainability compared to national water systems. The study published in Environmental Science and Ecotechnology found these shared basins average just 42 out of 100 on Sustainable Development Goals (SDG) metrics, well below the global national average of 67.
Researchers from Nanjing University, the Chinese Academy of Sciences, and Stockholm University developed a novel framework that combines Environmental Gini coefficients measuring resource inequality with 98 SDG indicators. This approach exposed stark regional disparities, with African basins scoring as low as 13 while European rivers exceeded 75. The analysis identified four distinct basin profiles requiring tailored interventions: institutional governance basins needing deeper cooperation, sustained growth basins struggling with water quality and poverty, inclusive growth basins balancing economic and environmental pressures, and social coordination basins vulnerable to climate extremes.
The findings demonstrate that isolated interventions yield limited results. Achieving clean water (SDG 6) alone would only bring 17 basins to sustainability. Combining clean water with economic growth (SDG 8) increases this to 17% of basins, but simultaneously addressing clean water, economic growth, and health (SDGs 3, 6, and 8) could elevate 38% of basins into sustainability. This multi-goal approach offers the most promising path for these critical shared resources that provide food, energy, and biodiversity while facing intensifying pressures from climate change, population growth, and competing national priorities.
Lead author Yiqi Zhou emphasized that the framework exposes hidden inequalities that national statistics overlook, providing policymakers with a decision-making compass for targeted investments in infrastructure, governance reforms, and cross-border agreements. The study's integrated strategies could help ease geopolitical tensions, build climate resilience, and accelerate progress toward multiple Sustainable Development Goals in some of the world's most sensitive shared river systems.
