Gap dynamics Gap dynamics is the pattern of plant growth that occurs following the creation of a forest gap, a local area of natural disturbance that results in an opening in the canopy of a forest. Gap dynamics are a typical characteristic of temperate and tropical forests, and have a wide variety of causes and effects on forest life. Sometimes special tools, such as a tree planting barare used to make planting of trees easier and faster. For a example, in arid zones, once forest cover is destroyed, the land may become dry and inhospitable for the growth of new trees.

Messenger For the first time, China has hosted a major global event on desertification and land degradation, the Cop, United Nations Convention to Combat Desertification.

The event took place in Ordos, in Inner Mongolia, a region known for its water-limited environments. Such areas commonly referred to as drylands occupy about half of the planet and are often sensitive and prone to change because of limitations in water and extreme temporal variability in rainfall.

China has successfully implemented various afforestation programmes over the year to make drylands viable for its economy, and will continue until The Loess Plateau is part of this dryland region, an area of the size of France.

Loess is a wind-blown sediment, transported by wind from the Gobi desert for millenia. The Loess Plateau is the cradle of the Chinese civilisation because the soils formed on Loess are very fertile and easy to farm. But Loess soils are extremely prone to erosion by water and wind.

Centuries of mismanagement resulted in degenerated land and in huge sediment loads in the Yellow River. Up to three Gigatonnes per year of sediment load was observed in the Yellow River in the late s. Map of the Yellow River, whose watershed covers most of northern China and drains to the Yellow Sea, Forests were not just established to minimise soil erosion by water but also to combat land degradation in northern China, a plague that significantly reduces the amount of farmland and thus threatens the sustainable regional development.

But, while soil erosion and the sediment load of the Yellow River have decreased, the water discharge of the river, the third largest in Asia, has significantly declined.

Afforestation has also had an important impact. This increase has largely contributed to the decline in water resources in northern China because forests evaporate more water than other land covers. And the newly established forests develop generally more slowly due to water shortage, are prone to diseases, and show poor vegetation stability.

The Shandong Ecological Afforestation Project aimed to support the provincial target to develop around , hectares of ecological afforestation in the period of the 12 th Five-year Plan (), and a longer-term goal to increase the province’s forest cover to 23 percent by China and India are leading countries in the overall project registration. Following table provides detail information about the registered CDM project under the category Afforestation and Reforestation.

Improving water management To prevent further decline in water resources, China needs to establish an integrated management of forests, land and water.

Implemented measures should be tailored to local environmental conditions.

For instance, there should be no afforestation in regions with rainfall less than mm per year. For such drought-prone zones, the establishment of grassland would be a better solution because it stabilises the soil while also ensuring the recharge of depleted water resources.

Introducing native tree species that use less water or the establishment such as the Savannah-like forests, which have fewer trees, can also ease drought conditions. Finally, natural re-vegetation should be promoted because it creates more stable forests.But in an extensive analysis of such “afforestation” efforts published last year in Earth Science Reviews, Beijing Forestry University scientist Shixiong Cao and five co-authors say that on-the-ground surveys have shown that, over time, as many as 85 percent of the plantings fail.

China has successfully implemented afforestation to counter desertification.

Control soil erosion Fritz Wobig China has invested more resources than any other country in reversing deforestation and planting trees. However, given the large scale of these programmes it has been difficult to quantify their impact on forest cover.

But, today, it faces another risk: its waters are declining. China's fight against desertification should not be done. Long-term afforestation efforts increase bird species diversity in Beijing, China.
