of water. Water resources of Poland, both own and total, are small, also in reference
to smaller neighbouring countries.
The relative amount of water resources of a country is provided by the water
abundance index, expressing the amount of water per capita in a year. Its amount can
be referred only to own resources, or to total renewable resources (Fig. 4.3). Among
European countries, Poland together with the Czechia and Belgium are included in
a group of countries with the smallest water resources – approximately 1500 m
3
per capita. It should be emphasised that the level of resources of 1000–2000 m
3 per
capita is considered very small. The highest index of total water resources concerns
Finland and Sweden. For Europe, the index is 4500 m
3 per year.
Water resources on particular continents per capita in a year are mostly different,
averaging 18.1 m
3 ·d
−1 per resident [5, 6]. This results both from the conditions of
the natural environment and from the number of residents. They are the highest in
Australia and Oceania (199.6 m
3 ·d
−1 per resident), twice lower in South America
(88.4), and three times lower in North America (65.6). On the remaining continents,
they are considerably lower: in Asia (9.5), Europe (10.9), and Africa (12.2 m
3 ·d
−1
per resident).
