Desertification is expanding, what should we do?

(planting trees and vegetation) can be done.

All of us should take an active part in protecting the land where we live.

first, establish and strengthen multidisciplinary comprehensive research on desertification. The occurrence of desertification begins with soil wind erosion caused by vegetation destruction, and it is first manifested as a natural environmental problem. Therefore, in the past, we simply started from the perspective of environmental governance, and the corresponding research viewpoints and control countermeasures were also concentrated or came from the research work of desert science. Its governance effect is not obvious, showing a state of point improvement, surface destruction, local improvement and overall deterioration, which is mainly the result of circuitous governance due to the limited understanding in the past. With the increasingly serious problem of desertification, we have realized that its main cause is population pressure and its uneconomical behavior. To solve the problem of desertification, we should not only be confined to "planting trees and grass", but also start from solving the excessive population pressure on desertification land. Therefore, it is necessary to break through the limitation of previous sand control technology and further study the problem of desertification control from the perspective of combining economics, demography, sociology, ecology, desert science and even more disciplines. Only with the continuous enrichment of relevant theoretical research results can desertification control move towards a more scientific road.

Second, build an eco-economic system for sustainable development in desertification areas. Desertification areas are usually weak or unsustainable areas, and a series of bad circulation factors such as environmental deterioration caused by population pressure have kept the relationship between man and land in a state of tension. Therefore, desertification areas often fall into a "dilemma" choice. On the one hand, the problem of environmental deterioration is caused by insufficient development and development. Without development and development, the problem of environmental deterioration will be more serious; On the other hand, if we want to solve the problems of exploitation and development, it may further damage the environment. But in any case, the development problem is the fundamental problem, and the fragility of the environment should be taken into account at the same time. Therefore, to engage in production and development in this special area, we must build a sustainable ecological and economic system. The goal of constructing eco-economic system is to achieve eco-economic balance, so that ecological balance and economic balance are relatively unified, and in this relatively stable dynamic balance state, both ecological law and economic law can play an effective role. Its function is manifested in the reduction function of production, life and purification, which transforms natural materials into economic materials to meet human needs, natural energy into economic energy flow with high quality energy, and economic energy flow into an important factor to restore natural energy. For example, building a grassland eco-economic system through industrialized management.

Third, establish a governance mechanism of scientific innovation with the state as the main body. Due to the social commonweal nature of ecological engineering construction, coupled with the weak economic foundation in desertification areas, the general difficulties in local finance and the high proportion of poor people, the state should be the main investor in desertification control, and incorporate desertification control into its capital construction plan. According to the detailed investigation of desertification areas, the project will be invested in stages by increasing financial transfer payments, and the operating mechanism of public welfare governance will be transformed into profit governance. For industrial development projects in governance engineering construction, the state will adopt discount loans to encourage various investments. In addition, the local governments provide some funds according to a certain proportion, and the masses invest paid labor to fully mobilize the enthusiasm of sand control in desertification areas. The construction of desertification control project should be a comprehensive control project combining with industrial development and construction to restore and improve the ecological environment, and the previous practice of "spreading pepper noodles" and unsupervised must be changed. Only by establishing a governance mechanism with constraints and incentives as soon as possible can the enthusiasm and initiative of governance and supervision in desertification areas be fully mobilized; Only by establishing and perfecting a legal desertification control system as soon as possible can we increase the effectiveness of governance and protect the results of governance, so that desertification areas can enter the track of sustainable development.

Fourth, highlight the idea of "people-oriented" and focus on solving the problem of economic development in desertification areas. Since people's uneconomical behavior is the fundamental cause of land desertification, we should change the traditional concept of conquering "nature", highlight the idea of "people-oriented" and focus on solving the problems of people's survival and development. For example, changing the combination of production factors through the application of high technology, improving the grain output of desertification land and developing sand industry; Vigorously promote the intercropping of grain and grass and develop the ternary structure planting model of grain-feed-cash crops; Vigorously promote the industrialization of desertification areas and transfer the population pressure from agriculture to industry and tertiary industry along the industrial chain; In areas where desertification is extremely serious, appropriate consideration should be given to immigration development methods. Only in this way can we fundamentally alleviate the pressure of land desertification and achieve effective control results.
