1. Will there be enough land and plant
nutrients to feed a world of
9 billion in 2050 ?
November 2012

2. In the 2050’s the world population will climb
up to approximately 9,3 billion, while at
present our world has already reached the
limit of arable lands which are reducing day
by day, because of misuse of earth, pollution
of enviroment, inadequate settlements and
other reasons.

5. In many parts of the world, as well as in
Europe, we are now testing the limits of the
resilience and multi-functional capacities of
soil.Globally, nearly 2 billion hectares of land
are affected by human-induced degradation
of soils (UN 2000). The food needs of
increasing populations is leading to even
greater intensification of agriculture,
streching thereby the capacity of soils to
release and absorb nutrients and chemicals.

6. Expension of built-up areas and
infrastructure, particularly in large urban
agglomerations, is sealing off the soil from
productive uses.
Each year an additional 20 million hectares
of agricultural land become too degraded for
crop production, or are lost to urban sprawl.
Soils are being degraded physically and
chemically due to erosion, exhaustion
(nutrient depletion) and pollution.

7. Soil’s diverse living organisms are being
reduced, and consequently the cleaning and
filtering capacities of soils in many localities
are being damaged beyond repair.
Soil is a limited and not renewable resources,
and unlike air and water damage to soil is
not easily
recoverable.

8. Average global temperatures are projected
to rise by between 1.4 and 5.8 ˚C by 2100. By
2030 the increase will be rather lower than
this between 0.5 and 1 ˚C .
Mean sea level is projected to rise by 15 to
20 cm by 2030 and by 50 cm by 2100.The rise
will lead to the loss of low-lying land through
flooding, seawater intrusions and storm
surges.

9. Under the EC baseline
scenario, the water erosion
risk is expected to increase by
the year 2050 in about 80% of
EU agricultural areas, as an
effect of climate change.

11. To create a wealth by excessively consuming
the world’s resources and making impossible
demands to the environment is no more
possible.Therefore we must accept more
adequate consumption models for utilizing
the world and human resources more
rationally and must change from
consumptive to thrifty
economy. Nasa visible earth-Norman
