Top 100 Countries by Freshwater Resources per Capita, 2026 Edition

Key facts about the freshwater resources ranking

What the freshwater resources per capita ranking shows

Freshwater resources per capita combines geography with demography. Countries with large river systems, high rainfall, major lakes, glaciers, groundwater recharge or important transboundary inflows can rank high when those resources are divided by a relatively small population. This explains the strong positions of Iceland, Guyana, Suriname and the Republic of the Congo.

The metric is not a direct measure of water security. It does not show whether water is close to farms and cities, whether it is clean, whether it can be stored, or whether utilities can deliver it reliably. A high-ranking country may still face floods, seasonal shortages, pollution, poor infrastructure or regional imbalance. A lower-ranking country may still provide strong water services through storage, reuse, leakage control, treatment and efficient allocation.

The most precise interpretation is country-level renewable freshwater endowment per person. It is useful for comparing long-term natural water-resource pressure, but it should not be used as a shortcut for judging drinking-water access or overall resilience.

Top 20 countries by freshwater resources per capita

The Top 20 is concentrated in the North Atlantic, northern South America, the Congo Basin, the Pacific and several low-density countries with large renewable flow systems. The gaps are wide: Iceland’s per-capita value is several times higher than most countries in the Top 20, while the lower end of the group remains far above many densely populated or arid economies.

The chart highlights the steep drop from the top two countries to the rest of the leading group. Per-capita water-resource rankings are therefore best read as a distribution, not as a simple label of abundance or scarcity.

Methodology: how the freshwater resources per capita ranking was calculated

The ranking uses total renewable freshwater resources per capita, expressed in cubic metres per person per year. Total renewable freshwater resources include internally generated renewable flows and relevant external inflows where they are part of the country’s renewable water-resource balance.

The 2026 label is an edition year. FAO AQUASTAT treats renewable water-resource variables as long-term annual averages, typically based on historical hydrological reference periods. The indicator is therefore suitable for structural comparison between countries, but it does not measure current drought, reservoir levels, monthly rainfall or short-term climate anomalies.

Countries were sorted from highest to lowest m³/person/year. Aggregate regions, income groups and non-country groupings were excluded. Values were rounded to the nearest cubic metre per person per year for readability. Standard English country names are used where official dataset labels differ from common reader-facing names.

The main limitation is that renewable freshwater resources are not the same as fully exploitable water. Some flows are difficult to capture, environmentally reserved, seasonal, geographically distant from demand centres or exposed to flood and drought variability. The ranking should be read together with water withdrawals, water stress, infrastructure quality, water governance, access to safely managed drinking water and climate-risk indicators.

The table ranks countries by total renewable freshwater resources per person. The figures are long-term resource indicators, so they are most useful for comparing structural freshwater endowment rather than short-term water availability.

Insights from the Top 100 freshwater resources ranking

• Population size strongly affects the result. Countries with moderate or large water systems can rank very high when their populations are small, while highly populated countries can rank lower even if their absolute freshwater volume is substantial.
• South America has a strong upper-tier presence. Guyana, Suriname, Peru, Paraguay, Uruguay, Bolivia, Chile, Venezuela, Colombia and Brazil all appear high because the continent combines major river basins with large renewable flows.
• Water-rich does not mean water-secure. Renewable freshwater may be seasonal, remote, polluted, hard to store, environmentally protected or unevenly distributed across a country.
• Transboundary water adds political and hydrological complexity. Countries can depend on rivers, lakes or groundwater systems shared with neighbours, so treaties, upstream withdrawals and climate variability can influence practical availability.
• The lower part of the Top 100 still includes countries with meaningful resources. A position near rank 100 does not necessarily indicate severe scarcity; it means the per-capita renewable resource value is lower than in the highest-ranked countries.

What this ranking means for readers, investors and policymakers

Freshwater resources per capita is a useful first signal of long-term water-resource pressure. For policymakers, a lower value can point to the need for stronger demand management, irrigation efficiency, water reuse, desalination, leakage reduction, drought planning and cross-border water diplomacy. For businesses, it helps frame exposure to agricultural, industrial and infrastructure risks.

For readers, the ranking helps separate natural endowment from service delivery. A country may have abundant renewable flows but still need major investment in pipes, treatment plants, storage, monitoring and watershed protection. Conversely, countries with limited natural freshwater can perform well if governance, infrastructure, pricing and technology are strong.

The indicator should be read alongside water stress, withdrawals by sector, access to safely managed drinking water, climate risk, reservoir storage and local water quality. Used this way, it becomes a practical tool for understanding resilience rather than a shortcut for judging overall water security.
