Last January I decided to start an annual update of the world's
population and of resources critical to human survival. Some data, like
population estimates and grain production, are relatively easy to check
on. For other data the quality of the information is quite uneven, or
statistics are only updated every few years. That said, the tables below
contain the best guesses of where we are with population, fisheries,
forests, grain and fresh water. For all these resources, the amount
available per person is going down as a result of the continued increase
in human population. That is because the resource is essentially fixed
(Internal Renewable Water Resources), because growth in the resource is
leveling off (world grain production), or because of decline in the
resource (overharvested fish and forests). Fisheries, Forests, Grain and Water:

INTERNAL RENEWABLE WATER RESOURCES
World Resources:
http://www.wri.org/wri/wr-98-99/
and US Census Bureau:
http://www.census.gov/ipc/www/idbnew.html
Countries and populations with less than 1000 cubic meters of internal renewable water
resources (rainfall). The 1000 cubic meters includes water required for meeting a person's
food, domestic and industrial needs. Lack of rainfall can be made up by taking water from
rivers running through a country, by pumping groundwater or by importing grain instead of
growing it.
| year | number of countries | number of people | average annual change |
| 1990 | 27 | 490,787,000 | no data |
