1. Mitigation and adaptation strategies with respect to impacts of climate change/variability and natural disasters Wang Shili Chinese Academy of Meteorological Sciences

2. Climate change will bring out remarkable impacts on natural ecosystem and socio-economy, some impacts are catastrophic and irreversible. It is necessary to study the impacts and adopt the adaptive measures in advance in order to mitigate the adverse influence. Climate variability results in the instable of agricultural production, the impacts of extreme climate events and various disasters are increasing around the world.

3. Mitigation and adaptation strategies with respect to impacts of climate change

4. Up till now the study on climate change and its impacts have made many progress. However the issue of mitigation and adaptation strategies with respect to impacts of climate change is not played much attention, the relative study is rather insufficient and weakness, and it is difficult to implement and practice. there is a long way to go.

5. Reduce emission of green house gasses to improve the efficiency of energy use to use clean and renewable energy-wind resources, solar resources to reduce the emission from agricultural practice, such as deforest, combusting residence, paddy field control to increase tree planting and forestry acreage

6. Develop sustainable agriculture to breed and improve crop cultivars and varieties with resisting adverse strain and high photosynthesis efficiency adjust cropping system and layout arrangement, such as changing cropping into animal husbandry in marginal areas, improve the ability of absorbing co2 of agricultural practice_maize crop

7. develop save-water agriculture, reasonable irrigation scheme develop traditional agricultural practice which are favor and friendly to environment protection, straw mulching, water harvest Prepare and control pest, disease and weeds, develop reagents without pollution, biological control techniques

8. Protect ecological environment and reasonable land use Water erosion control Avoid over-grazing, develop optimal animal husbandry strategies according to reasonable animal capacity Promote concordant, integrated agricultural development in vulnerable regions.

9. Latent heat flux is reduced Wheat yield increased by 18.5%, water use efficiency was improved by 22.1%. straw mulching

10. Water harvest

11. A project to shift farm land to grassland or forest in western part of China arid semi-arid regions vulnerable ecological environment less arable land pool agricultural production

12. Serious soil erosion soil and water control by grass

13. Crop are planted in lower and flat layer

14. Strength water resources management Enhance water resources planning and control (ecological water usage, agricultural irrigation water usage and resident life water usage), improve water use efficiency Develop cloud water resources in atmosphere, sea water processing

15. Coastal management Monitor raise of sea level Build the coastwise safeguard Develop early warning system of extreme climate events

16. Training and education Improve the public aware of climate change and mitigation impacts of climate change Strength training and education for farmers.

17. Reducing impacts of climate variability on sustainable agriculture

18. Monitor agro-meteorological condition based on station observation network, remote sensing and GIS Assess impacts and risk analysis Apply seasonal prediction in agricultural production

19. Drought is one of the most severe meteorological disasters With characteristic of slow development, long duration, wide stricken area and severity. Significant impact on hydrology, agriculture, eco-environment, economy and society
