The role of coconut trees at risk of climate change globally

According to the World Bank (WB) climate change seriously is happening on a global scale, and Vietnam is one of the countries most severely affected. Relief organization Action (Action Aid) said that climate change is a direct threat to Vietnam, directly affect the safety of people and the economy. The forecast said that if sea levels rise by 1 meter, Vietnam is likely to lose at least 12.2% of land area, the residence of 23% of the population (17 million), mainly concentrated in Red river delta (RRD) and Cuu Long (Mekong), causing economic losses of up to US $ 17 billion (10% of GDP) [ICEM presentation, 2009].

Climate change makes the storm of floods occur more often with devastating levels more severe, and many strange disease appeared and raging not just localized in one geographical area small. This requires planning of productive land, plant structure must also change.

According to the United Nations Development Programme (UNDP), Vietnam in the list of the world's five top countries most vulnerable to climate change. If sea levels rise, this is 3-5m- synonymous with "probable catastrophe" in Vietnam.

Salt water is increasing its penetration in the Mekong Delta provinces. Until now salt water intrusion into the provinces of Kien Giang, Tra Vinh, Tien Giang, Hau Giang, Vinh Long. Ben Tre in saltwater has encroached deep into 3 Giong Trom District, Ba Tri and Binh Dai, from 5-27% 0 salinity. On the Ham Luong River, salt water has encroached deep into to the Ham Luong Bridge. Thousands of hectares of crops have been affected. In Tien Giang, salt water flowed into rivers Vam Co Dong and Vam Co Tay. Giuoc district, on the river Rach Cat measured salinity 0 to 11.6%.

In terms of climate change, will plant a coconut tree is resistant to brackish soil, the soil salinity intrusion in the dry season. Coconut is a crop adapted to climate change because it keeps the height of the water table, erosion control. Coconut trees form a powerful bulwark against wind and reduce damage caused by the storms and tornadoes caused. In addition, coconut palms and creative rejuvenation of land for less use of chemical fertilizers and pesticides.

Global warming is one concern in certain ?, not the coconut "! The Institute noted in industrial plants India (CPCRI) revealed that higher temperatures and high CO2 levels increase the productivity of coconut in the west coast of India. Coconut productivity will increase 10% in 2020, increased 16% and 36% in 2050 and 2080 due to climate change at the west coast of India created [S. Naresh Kuma; PK. Aggarwal, 2013]. Thus, there can still crops, especially palm tree positive adaptation to the impacts of climate change. Coconut plantation along with the economic activity related to the coconut tree in general has helped create opportunities for smallholders, fishermen in the vulnerable areas can participate in order to adapt to and lessen harmful effects of climate change and ecological balance, stable life.

In agriculture to adapt and mitigate the impact of climate change is the key to the problem and the establishment of agricultural systems and sustainable management practices will contribute to mitigating the effects of climate change Hau. Coconut trees are the answer to the risk of climate change and sea level rise, the trees of the millennium goals.
