"Environmental Problems and Governance in Agricultural and Pastoral Areas" PPT courseware

Part 1: What is green food?

Green food refers to safe, high-quality, nutritious food that follows the principle of sustainable development, is produced according to specific production methods, is recognized by a specialized agency, and is allowed to use the green food label, and is pollution-free. "Produced according to specific production methods" refers to the prohibition or restriction of the use of chemically synthesized pesticides, fertilizers, additives and other production materials and other substances that may cause harm to human health and the ecological environment during the production and processing process in accordance with green food standards. , and implement full-process quality control "from land to table".

Green food is divided into Grade A and Grade AA. Grade AA green food follows the same principles and standards as organic food.

In accordance with organic agricultural production standards, organic chemically synthesized fertilizers, pesticides, growth regulators, livestock and poultry feed additives and other substances are not used in the production process, and organisms and their products obtained by genetic engineering technology are not used, but natural laws and ecology are followed. Based on scientific principles, we adopt a series of sustainable agricultural technologies, coordinate the relationship between planting and animal husbandry, and promote ecological balance, species diversity and sustainable utilization of resources.

Green food and green barriers

Green barriers, also known as environmental barriers. It refers to the trade barriers that restrict the access of foreign goods through legislation or the formulation of strict mandatory technical regulations by some countries in the field of international trade by virtue of their scientific and technological advantages and for the purpose of protecting the environment and human health.

Although the formation of green barriers has only occurred in the past 10 years, it has become increasingly globalized and is developing at an accelerated pace. Since the 1990s, developed countries have successively formulated a series of "green standards". For those who do not meet the regulations, developed countries have adopted various restrictive and punitive measures such as bans and restrictions on imports.

Environmental problems in agricultural and pastoral areas and their management PPT, Part 2: Environmental pollution in agricultural areas

In recent years, some rural areas in my country have been increasingly polluted by domestic sewage and industrial wastewater from cities. The water pollution and land pollution caused by "pollution going to the countryside" have seriously affected the life and health of rural residents and undermined the sustainable development of the rural economy.

In rural areas, farming relies too much on chemical fertilizers, resulting in high levels of chemical fertilizer application. , but the utilization rate is only about 40%, and the remaining 60% of chemical fertilizers are contributed to soil and groundwater. In 2000, the average pesticide application rate in China was 13.4 kg/hectare, of which organophosphorus pesticides accounted for 70%; highly toxic pesticides accounted for 70%; insecticides accounted for 70%; 60-70% remained in the soil.

A kind of white pollution, namely pesticide film pollution, is also very serious. At present, about 500,000 tons of agricultural film remain in the soil in China every year, with a film residue rate of 40%.

More than 100 million tons of straw are burned directly in the open every year, accounting for 17% of China's total straw production. The amount of pollutants produced by livestock and poultry breeding is more than twice that of industrial solid waste. In some areas such as Henan, Hunan, and Jiangxi, it even exceeds 4 times.

Environmental problems and their governance in agricultural and pastoral areas PPT, Part 3: Developing ecological agriculture

Characteristics of ecological agriculture:

Comprehensive. Ecological agriculture emphasizes giving full play to the overall function of the agricultural ecosystem, taking large agriculture as the starting point, and comprehensively planning, adjusting and optimizing the agricultural structure according to the principles of "wholeness, coordination, circulation, and regeneration" so that agriculture, forestry, animal husbandry, and fishery industries and The primary, secondary and tertiary industries in rural areas are comprehensively developed and all industries support each other and complement each other to improve comprehensive production capacity.

Diversity. In view of the vast territory of our country and the large differences in natural conditions, resource base, economic and social development levels in various places, ecological agriculture fully absorbs the essence of our country's traditional agriculture, combines it with modern science and technology, and uses a variety of ecological models, ecological projects and rich and colorful technologies. Types of equipment for agricultural production enable each region to leverage its strengths and avoid weaknesses, give full play to regional advantages, and all industries develop in coordination with social needs and local realities.

Efficiency. Ecological agriculture achieves economic value-added through multi-level comprehensive utilization of materials and energy and serial deep processing, implements waste resource utilization, reduces agricultural costs, improves efficiency, creates internal agricultural employment opportunities for a large number of rural surplus labor, and protects farmers' ability to engage in agriculture. Positivity.

Persistent. Developing ecological agriculture can protect and improve the ecological environment, prevent and control pollution, maintain ecological balance, improve the safety of agricultural products, change the conventional development of agriculture and rural economy into sustainable development, closely integrate environmental construction with economic development, and satisfy the needs to the greatest extent. In addition to people's growing demand for agricultural products, it will also improve the stability and sustainability of the ecosystem and enhance the potential for agricultural development.
