1, desertification is particularly harmful to agriculture. April to May is the spring sowing season every year. In desertification areas, seeds and fertilizers are often blown away, seedlings are uprooted, soil moisture is lost, and seedlings are blown to death or buried. In some places, folk remedies have to be repeated and even the farming season has been missed.

2. Grassland degradation caused by desertification gradually reduces or even completely loses the dominant grass species suitable for livestock growth. Pasture becomes low and sparse, the yield is obviously reduced, and the livestock carrying capacity of grassland is greatly reduced.

3. Desertification leads to the blockage of rivers, reservoirs and canals. The Yellow River transports 654.38+0.6 billion tons of sand every year, of which 654.38+0.2 billion tons comes from desertification areas. More than 50,000 kilometers of irrigation canals in China are harmed by sandstorms all the year round.

4. In some areas, desertification has destroyed railway subgrade, bridges and culverts, made road subgrade and pavement desertification, forced road traffic to be interrupted, and even abandoned roads. The dusty weather caused by desertification affects the normal take-off and landing of aircraft.

5. Sandstorm activities destroy communication and transmission lines and facilities, and the resulting disasters threaten the safety of residents. According to monitoring, urban air pollutants in China are mainly tiny particles, which are closely related to desertification.

6. Dust pollutes people's production and living environment in vast areas and affects people's health.

7. Desertification has deepened poverty and widened regional disparities. According to the survey, the rural population in China14 lives in desertification areas, and its per capita agricultural output value is only 34. 2%, which is 1/5 in the eastern region. Poverty in desertification areas has intensified and the development gap has widened. Some places shouted the slogan "In order to survive, we must control desertification".
