The earth continues to warm up. The past eight years are on track to be the eighth warmest on record, according to Provisional State of the Global Climate in 2022released by the World Meteorological Organization (WMO) .

The impact of climate change on agriculture and energy is of grave concern to the entire world.

To respond to this situation and mitigate the impact, China is trying to adjust agricultural production layout and develop clean energy through science and technology.

Against the backdrop of climate change, China has taken sustained actions. For example, climate change is now considered as an important parameter in formulating China's food security policy.

“Climate change also affects the growth and activities of different creatures, including insect pests and plants.” said Lu Bo, Director of Climate Change Impacts Adaptation Room, National Climate Centre (NCC).

In response, China Meteorological Administration (CMA) has analyzed the impact of climate change on food cultivation, insect pests and plant diseases, adaptability of different kinds of corps, crop yield and so on. The quantitative relationship model between extreme weather and climate events and crop yield assessment has been established.Agricultural loss assessment model of extreme weather and climate events at the national and regional levels has been developed. All these measures have provided support for reducing agricutural losses and risks.

“Agricultural climatic zoning based on crop climate adaptability can provide guidance for food production, which plays an important role in the adjustment of agricultural production layout in China.” said Lu Bo.

Due to global warming, some boundaries of climate zones in China have changed, so should the planning of agricultural zoning.

Quantitative assessment of the impact of climate change on food production and security is vital for promoting sustainable agricultural development. Prediction of the impact of extreme climate events on agricultural production is necessary for safeguarding food security.

Meanwhile, the supply of electricity from clean energy sources is increasing. In recent years, China is making scientific breakthroughs in increasing clean energy efficiency.

An increasing number of wind turbines are being built.

“We have conducted in-depth research on the spatial and temporal complementarity of wind power and photovoltaic power generation, drawing a map of optimal ratio of wind power and photovoltaic power generation in different regions of China, supporting China's energy transformation.” said Dr. Qiu Shuang from NCC.      

The development potential, spatial distribution and temporal variation of China's wind and solar energy resources have been basically identified.

Wind power is one of the world‘s fastest-growing sources of renewable energy.

It's noting that FENGYUN meteorological satellites have played a crucial role in the development and utilization of wind energy and solar energy resources.

“Thanks to FYmeteorological satellites, we are building atlas of refined distribution of solar energy resources for countries like Nepal, Malaysia and the Philippines” said Shen Yanbo, scientific director of Wind Energy and Solar Energy Centre of CMA.

CMA is looking forward to exchange ideas, promote sharing and join hand with countries to better respond to climate change, said Chao Qingchen,Director of NCC.
