When prolonged drought people remember to plant trees and forests.
Countries with large deserts have less water.
At this moment there are know how to transform deserts in Forests.
The technique name is Permaculture. And is proven to be functional.
Some countries remembers that the attention you pay to the forestation is in direct relation with the amount of rein it receives and the well being of the people.
The extent, and type of land use directly affects wildlife habitat and thereby impacts local and global biodiversity. Human alteration of landscapes from natural vegetation (e.g. wilderness) to any other use typically results in habitat loss, degradation, and fragmentation, all of which can have devastating effects on biodiversity. Land conversion is the single greatest cause of extinction of terrestrial species
Rates and causes of deforestation vary from region to region around the world. In 2009, 2/3 of the world forests were in 10 top countries: 1) Russia, 2) Brazil, 3) Canada, 4) United States, 5) China, 6) Australia, 7) Congo, 8) Indonesia, 9) Peru and 10) India.
World annual deforestation is estimated as 13.7 million hectares a year, equal to the area of Greece. Only half of this area is compensated by new forests or forest growth. In addition to directly human-induced deforestation, the growing forests have also been affected by climate change, increasing risks of storms, and diseases.
Canada
In 2005, an estimated 56,000 hectares were deforested in Canada. Deforestation affected less than 0.02% of Canada’s forests in 2005. The agricultural sector accounted for just over half of the deforestation in 2005, the result of forests having been cleared for pasture or crops. The remainder was caused by urban development, transportation corridors, and recreation (19%); hydroelectric development (10%); the forest sector (10%); and other natural resource extraction industries (8%). About two thirds of this deforestation occurred in Canada’s boreal forest, mainly in Alberta, Saskatchewan, and Manitoba where the forest borders the Prairies
In Canada, prior to 2000, less than 8% of the boreal forest was protected from development and more than 50% has been allocated to logging companies for cutting

United States
Prior to the arrival of European-Americans, roughly half of the land
area of the present-day United States was forest—about 4,000,000 square
kilometres (990,000,000 acres) in 1600. For the next 300 years land was
cleared, mostly for agriculture, at a rate that matched the rate of
population growth. For every person added to the population, one to two
hectares of land was cultivated.
This trend continued until the 1920s
when the amount of crop land stabilized in spite of continued population
growth. As abandoned farmland reverted to forest, the amount of
forestland increased from 1952, reaching a peak in 1963 of 3,080,000
square kilometres (760,000,000 acres). Since 1963 there has been a
steady decrease of forest area with the exception of some gains from
1997.
Nigera
According to the FAO, Nigeria has the world's highest deforestation rate
of primary forests. It has lost more than half of its primary forest in
the last five years. Causes cited are logging, subsistence agriculture, and the collection of fuel wood. Almost 90% of West Africa's rainforest has been destroyed.
Romania
A high percentage (47% of the land area) of the country is covered with natural and semi-natural ecosystems. Since almost half of all forests in Romania (13% of the country) have
been managed for watershed conservation rather than production, Romania
has one of the largest areas of undisturbed forest in Europe. The integrity of Romanian forest ecosystems
is indicated by the presence of the full range of European forest
fauna, including 60% and 40% of all European brown bears and wolves,
respectively.
Germany
In Germany,
reforestation is required as part of the federal forest law. 31% of
Germany is forested, according to the second forest inventory of
2001–2003. The size of the forest area in Germany increased between the
first and the second forest inventory due to forestation of degenerated bogs and agricultural areas.
China
In China, extensive replanting programs have existed since the 1970s.
Programs have had overall success. The forest cover has increased from
12% of China's land area to 16%. However, specific programs have had
limited success. The "Green Wall of China", an attempt to limit the expansion of the Gobi Desert is planned to be 2,800 miles (4,500 km) long and to be completed in 2050.
