1. Measures for sustainable agricultural development

1. Adjust the structure of agricultural industry and develop agriculture according to local conditions; control the growth of the rural population and improve the quality of the population; increase investment in agricultural science and technology, and accelerate the application and popularization of agricultural technology; develop water-saving agriculture and ecological agriculture; the combination of agricultural development and ecological environmental protection; extend the industrial chain, increase the added value of agricultural products, and increase farmers' income; strengthen the construction of agricultural infrastructure and improve the conditions for agricultural production; Improve the agricultural ecological environment and promote the sustainable development of agriculture.

2. Sustainable development agriculture refers to an agricultural system that adopts a certain way of rational use and maintenance of natural resources, implements technological changes and institutional reforms, and ensures the sustainable development of the demand for agricultural products of the present and future generations.

3. Sustainable agriculture is an agriculture that continuously meets the needs of contemporary human beings for the quantity and quality of agricultural products through the management, protection and sustainable use of natural resources, and adjusts agricultural systems and technologies, without harming the interests of future generations.

2. Sustainable agricultural zoning

In view of the problems faced by the sustainable development of agriculture in various regions, the country is divided into optimized development areas, moderate development areas, and protected development areas by comprehensively considering the carrying capacity, environmental capacity, ecological type and development foundation of agricultural resources in various regions, and the direction and focus of sustainable agricultural development in different regions are determined in accordance with the principles of adapting measures to local conditions, echelon advancement, and classified policies.

1. The historical origin of the concept of "sustainable development" can be traced back to the logging industry in Germany in the first century. At that time, in response to excessive deforestation, the concept of "sustainable development" was proposed in order to ensure the normal and sustainable use of timber**.

2. Sustainable development of agriculture refers to the formation of a new pattern of agricultural development in agriculture that is resource-saving, environment-friendly, industrially efficient, and increases farmers' income.

"Sustainable agriculture" is an extension of the concept of "sustainable development" to agriculture and agriculture.

Zhi village economy is generated by dao. Joint Special Committee, 1991.

The FAO has developed the concept of sustainable agriculture (SAA), which is the management and conservation of the natural resource base and the reorientation of technological and institutional changes in order to ensure that the needs of present and future generations are met and met in a sustainable manner. It is therefore a tool that protects and maintains land, water, flora and fauna resources without causing environmental degradation; At the same time, agriculture that is technically feasible, economically viable, and socially acceptable.

The idea of sustainable agriculture has run through the whole process of agricultural production and has become an important guiding ideology for agricultural development.

Sustainable agricultural development refers to the development of agriculture to meet the needs of the present generation, and does not pose a special threat to the ability of future generations to meet their needs, that is, to achieve the purpose of developing agriculture, but also to protect the atmosphere, fresh water, ocean, land and forests and other natural resources and environment on which human beings depend, so that future generations can live and work in peace and contentment.

One is to increase output, but consume a lot of resources, such as oil, coal, etc., the result is that our current needs are met, but our children grow up without oil, coal and other non-renewable resources that can be used;

Second, enterprises increase output at the expense of the environment, and the emission of pollutants is serious, which affects the environment, which affects the living space of future generations and their quality of life.

That is why we advocate economic growth and increased output, but not to the detriment of future generations and not to the detriment of the environment.

The main factors influencing the sustainable development of agriculture include:

Sustainable development of population and agriculture.

Natural resources and agriculture can be sustained.

Sustainable development of environment and agriculture.

Technological progress and sustainable agricultural development.

Correct answer: Population and sustainable agricultural development, natural resources and sustainable agricultural development, environment and sustainable agricultural development, technological progress and sustainable agricultural development.

The challenges facing sustainable agricultural development mainly include the following aspects:

1.Shortage of land resources: With the acceleration of urbanization, land resources are increasingly scarce, which has brought great challenges to agricultural production, resulting in a decrease in land area and restrictions on agricultural production.

2.Water shortage: Water is one of the important conditions for agricultural production, but the current global supply and demand of water resources are seriously unbalanced, and water resources in many regions are already very scarce, which brings great challenges to agricultural production.

3.Impact of climate change: Climate change has a significant impact on agricultural production, such as changes in rainfall and temperature, and the frequent occurrence of extreme weather events, which will affect the productivity of crop cultivation and breeding.

4.Impact of natural disasters: Natural disasters such as floods, droughts, typhoons, etc., will also affect agricultural production, resulting in the reduction or loss of crop yields, thereby affecting the sustainable development of agriculture.

5.Lack of agricultural modernization: Despite the continuous progress of science and technology, the lack of agricultural modernization still limits the production efficiency and sustainable development of agriculture. For example, the development of agricultural mechanization and informatization is still insufficient.

6.Poverty: Rural poverty is one of the serious problems facing the world at present, which brings great difficulties to the sustainable development of agriculture and increases the instability and instability of agricultural development.

The challenges to sustainable agricultural development include the following:

1.Ecological and environmental protection: The large-scale, intensive and high-intensity traditional agricultural management methods have caused serious damage to the ecological environment.

2.Resource utilization and efficiency: There is a problem of excessive waste or over-exploitation in the utilization of Li Xianyuan in agricultural capital town, which relies on external production materials such as chemical fertilizers and pesticides, resulting in a decline in land quality and yield.

3.Climate change: The adverse effects of climate change on agricultural production include reduced rainfall, increased droughts, reduced water sources, and rising sea levels.

4.Rural population loss: With the acceleration of urbanization, rural population loss has intensified, resulting in a loss of agricultural productivity and an imbalance between social and economic development.

To meet these challenges, we need to optimize agricultural production methods, improve production efficiency, and promote technologies such as circular agriculture and sustainable planting to achieve sustainable agricultural development.

Challenges to sustainable agricultural development include: shortage of land resources, climate change, use of chemical fertilizers and pesticides, loss of biodiversity, lack of technological progress, poverty and malnutrition, popularization of agricultural technology, and insufficient market competitiveness of agricultural products.

2. Sustainable agricultural zoning

In view of the problems faced by the sustainable development of agriculture in various regions, the country is divided into optimized development areas, moderate development areas, and protected development areas by comprehensively considering the carrying capacity, environmental capacity, ecological type and development foundation of agricultural resources in various regions, and the direction and focus of sustainable agricultural development in different regions are determined in accordance with the principles of adapting measures to local conditions, echelon advancement, and classified policies.

Modern agriculture is sustainable and therefore attaches importance to what is as follows:

The core concept of modern agriculture is the combination of planting and breeding, and sustainable development.

Modern agriculture is an agriculture developed on the basis of modern industry and modern science and technology, and it germinated in the period of capitalist industrialization. Its main characteristics are the extensive application of modern science and technology, from conforming to nature to consciously using and transforming nature, from relying on traditional experience to relying on science, and becoming a scientific agriculture, so that it can be established on the basis of the high development of botany, zoology, chemistry, physics, and other sciences.

The core of modern agriculture is scientific and quiet, characterized by commercialization, the direction is intensive, and the goal is industrialization. The purpose of modern agriculture is agriculture developed on the basis of modern industry and science and technology.

Modern agriculture has made extensive use of modern advanced science and technology, from conforming to nature to using and transforming nature, from relying on traditional agricultural production experience to relying on science, and on the basis of the high development of botany, zoology, chemistry, physics and other sciences, a large amount of material and energy produced by the industrial sector has been put into agricultural production in exchange for a large number of agricultural products.

Characteristics: Its main characteristics are the extensive use of modern science and technology, from conforming to nature to consciously using and transforming nature, from relying on traditional experience to relying on science, becoming a scientific agriculture, so that it is based on the high development of botany, zoology, chemistry, physics and other sciences.

Invest a large amount of material and energy produced by the industrial sector into agricultural production in exchange for a large number of agricultural products, and become an industrialized agriculture; Agricultural production has embarked on the road of regionalization and specialization, changing from a natural economy to a highly developed commodity economy, and becoming a commoditized and socialized agriculture.
