Restoration refers to a farming method in which farmland that was once abandoned and no longer used is recultivated and cultivated to grow crops. In the past, the problem of land abandonment could indeed be solved by rehabilitation, because the population was small and the land resources were relatively abundant, and it was completely feasible to increase food production by increasing the area of cultivated land. However, with the increasing population and the acceleration of urbanization, the problem of land abandonment is far more than a simple area problem, and it cannot be solved by recultivation alone.
First of all, the core of recultivation is to increase the area of cultivated land. However, with the continuous growth of population and the acceleration of urbanization, limited land resources are being swallowed up by urban construction and industrial land, and the land area is gradually decreasing. Restoration is simply the reuse of existing farmland, and in the face of a serious shortage of land resources, even if the land that can be cultivated is recultivated, it is difficult to provide enough arable land to meet people's needs.
Second, the problem of land abandonment is not only related to the area of cultivated land, but also closely related to the ecological environment. Long-term large-scale farming has led to a decline in land productivity, the land has become barren, and the yield of crops has gradually declined. In order to restore the productivity of the land, land management and improvement are needed, such as improving soil quality through proper fertilization, crop rotation and fallowing. However, if only recultivation is carried out without solving the soil problem, it will be difficult to restore the yield to the optimal level even if the crops are replanted. Therefore, recultivation alone cannot solve the root cause of the problem of land abandonment.
In addition, the issue of land abandonment also involves the conservation of biodiversity. In the process of land being cultivated, farmland ecosystems are often destroyed, and a large number of ecological environments and biological habitats are destroyed. Recultivation may ensure land use, but not biodiversity. Biodiversity is essential for maintaining ecological balance and ecosystem stability, and if the conservation of biodiversity is neglected while only pursuing the improvement of crop yields, it will bring greater damage to the ecological environment and may eventually lead to more serious land abandonment.
To sum up, recultivation alone is not enough to solve the problem of land abandonment. Modern society should pay more attention to comprehensive land management, including the rational use of limited cultivated land resources, soil quality improvement, biodiversity protection and other measures. Only through comprehensive ecological protection and land management measures can we better deal with the problem of land abandonment and ensure the sustainable use of farmland. In the future development of agriculture, we should take into account the scarcity of land resources and the sustainability of the environment, and take more scientific and reasonable measures to achieve the sustainable development of agriculture.
