However, the conventional production mode leads to overconsumption of agricultural resources, increas- ingly challenging ecological environment impacts, and higher costs of agricultural products whose quality falls short of public expectations. The Central Committee of the Communist Party of China and the State Council both put ex- tra emphasis on agricultural supply-side reform, restructuring of the sector, and a shift in the production mode. This paper explains the significance of the agro-ecological compensation mechanism, analyzes the efficacy of China＇s current agricultural subsidy policies, introduces related experience from developed countries, elaborates options to establish the mechanism, and proposes policy recommendations to accelerate its development. This analysis con- cludes that one of the most important approaches to agricultural green development is to shift the existing subsidy policy from one which aims to ensure the yield by purchasing at a protective price, to a green subsidy which focuses on agro-ecological compensation.展开更多

Erhai Lake has felt this challenge keenly. To address it, in 2022, a Science and Technology Backyards(STBs) project was launched in Gusheng Village. The goal of this is to care for the environment while ensuring that farms and farmers can thrive sustainably. The uniqueness of the Erhai STB arises from its interdisciplinary integration, encompassing fields such as ecology, agronomy and social science, resulting in specifically-designed solutions for the Erhai context. While this model aligns with broader STB paradigms, its distinctive edge lies in technological innovation and robust support mechanisms for local agricultural stakeholders. This paper describes the methodology and outcomes of the STB initiative, highlighting its pivotal role in spearheading sustainable transition in Erhai. Preliminary findings underscore the potential of the STB model as an efficacious tool for harmonizing environmental conservation and agricultural practices, that are both financially and environmentally sustainable, rendering it a potential model for comparable regions in China and other counties.展开更多

To assess the agricultural transformation from 1997 to 2020, this paper proposes a national-scale indicator system consisting three dimensions(socioeconomic, food production and eco-environmental) and ten sub-dimensions to quantify the AGD score.This study showed that AGD score in China was at a moderate level during 1997–2010, scoring 40 out of 100. During this stage, decreased scores in the sub-dimensions of resource consumption, environmental quality, and environmental cost have offset the improvement in the socioeconomic dimension, resulting in fluctuated scores around 40. In the second stage(2011–2020), China's AGD score improved but still at moderate level, scoring an average of 46.3, with each dimension increasing by 5.3%–25.0%. These results indicate that China has made progress in the agricultural transformation, transitioning from conceptualization to actions through the implementation of various policies and projects. However, the study emphasizes the need for more effort to address the insufficient and unbalanced development, along with the growing eco-environmental challenges, especially the trade-offs among dimensions.展开更多

The rapid increase in population requires high inputs of N to meet the growing food demand. If not managed well, the substantial loss of N from the food system has multiple impacts on grain yield, air and water pollution, and the economic benefits of agricultural. Multi-objective(food security, environmental sustainability and economic sustainability) synergistic consideration of N management in the food system is still lacking. This study employed strategies for optimizing N management in the food system, using Quzhou County as a typical example on the North China Plain. Firstly, a food chain approach was adopted to understand drivers and reasons behind N losses from the food system.Secondly, a top-down approach was used to define multi-objective N management, taking into consideration food security, environmental sustainability and economic sustainability. Multi-objective N management aims to reduce N losses to the environment and increase N use efficiencies,while simultaneously increasing yields and economic benefits. Thirdly, 3R(reduce-retain-recycle) N management strategies were identified for specific crops and animals through a bottom-up approach and then analyzed the potential of these strategies to achieve the multi-objectives. Finally, there is a discussion of how to engage different stakeholders to promote the technologies implementation. This study provides new insights into the synergistic achievement of multi-objective N management in the food system and the development of environmentally-friendly agriculture.展开更多

The emissions of environmental pollution caused by meeting food demands have prompted some countries to intensify their climate change mitigation efforts. These circumstances have introduced significant uncertainty to the future global sustainable food development. Additionally, a notable global challenge is the persistence of hidden hunger, primarily characterized by the insufficient consumption of high-quality animal protein. Addressing this issue would necessitate increased environmental costs to attain high-quality food security. The future food system presents a significant challenge in coordinating food security, food quality and environmental quality. This article presents a comprehensive review and proposes a three-step strategy for future agricultural development based on food security, quality, and environmental aspects. This is a novel food system transfer strategy, as it concurrently addresses both global food security and environmental thresholds. It involves the construction of an efficient food system that operates within the constraints of environmental limits. The objective is to align with global SDG indicators and to maintain natural resource consumption and pollutant emissions within planetary boundaries.展开更多

Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development(AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.展开更多

Meanwhile, the development of eco-agriculture is inseparable from its technical support. At present, the eco-agricultural technologies commonly used in China can be divided into three categories according to their theoretical basis and practical types: the technologies used to realize the precision input of material resources, the technologies used to improve material circulation efficiency, and the technologies that use the principle of species symbiosis. Although these technologies provide essential support for developing eco-agriculture in China, there are also problems associated with their implementation, such as poor technical application and a low level of industrialization. Therefore, in the future development of eco-agriculture technology in China, the technologies producers should take the actual problems as guide and pay attention to the popularization, industrialization, and application of the technologies.展开更多

文摘China has initiated a green transformation plan in 2015, which was soon applied to agriculture, known as the agriculture green development(AGD)initiative, with the goals of achieving food security, high resource use efficiency, and an ecofriendly environment. To assess the agricultural transformation from 1997 to 2020, this paper proposes a national-scale indicator system consisting three dimensions(socioeconomic, food production and eco-environmental) and ten sub-dimensions to quantify the AGD score.This study showed that AGD score in China was at a moderate level during 1997–2010, scoring 40 out of 100. During this stage, decreased scores in the sub-dimensions of resource consumption, environmental quality, and environmental cost have offset the improvement in the socioeconomic dimension, resulting in fluctuated scores around 40. In the second stage(2011–2020), China's AGD score improved but still at moderate level, scoring an average of 46.3, with each dimension increasing by 5.3%–25.0%. These results indicate that China has made progress in the agricultural transformation, transitioning from conceptualization to actions through the implementation of various policies and projects. However, the study emphasizes the need for more effort to address the insufficient and unbalanced development, along with the growing eco-environmental challenges, especially the trade-offs among dimensions.

文摘Nitrogen(N) is an essential nutrient for food production. The rapid increase in population requires high inputs of N to meet the growing food demand. If not managed well, the substantial loss of N from the food system has multiple impacts on grain yield, air and water pollution, and the economic benefits of agricultural. Multi-objective(food security, environmental sustainability and economic sustainability) synergistic consideration of N management in the food system is still lacking. This study employed strategies for optimizing N management in the food system, using Quzhou County as a typical example on the North China Plain. Firstly, a food chain approach was adopted to understand drivers and reasons behind N losses from the food system.Secondly, a top-down approach was used to define multi-objective N management, taking into consideration food security, environmental sustainability and economic sustainability. Multi-objective N management aims to reduce N losses to the environment and increase N use efficiencies,while simultaneously increasing yields and economic benefits. Thirdly, 3R(reduce-retain-recycle) N management strategies were identified for specific crops and animals through a bottom-up approach and then analyzed the potential of these strategies to achieve the multi-objectives. Finally, there is a discussion of how to engage different stakeholders to promote the technologies implementation. This study provides new insights into the synergistic achievement of multi-objective N management in the food system and the development of environmentally-friendly agriculture.

文摘Realizing sustainable development has become a global priority.This holds,in particular,for agriculture.Recently,the United Nations launched the Sustainable Development Goals(SDGs),and the Nineteenth National People’s Congress has delivered a national strategy for sustainable development in China—realizing green development.The overall objective of Agriculture Green Development(AGD)is to coordinate"green"with"development"to realize the transformation of current agriculture with high resource consumption and high environmental costs into a green agriculture and countryside with high productivity,high resource use efficiency and low environmental impact.This is a formidable task,requiring joint efforts of government,farmers,industry,educators and researchers.The innovative concept for AGD will focus on reconstructing the whole crop-animal production and food production-consumption system,with the emphasis on high thresholds for environmental standards and food quality as well as enhanced human well-being.This paper addresses the significance,challenges,framework,pathways and potential solutions for realizing AGD in China,and highlights the potential changes that will lead to a more sustainable agriculture in the future.Proposals include interdisciplinary innovations,whole food chain improvement and regional solutions.The implementation of AGD in China will provide important implications for the countries in developmental transition,and contribute to global sustainable development.

文摘This paper has three aims.First,to examine how the negative environmental consequences of intensive agriculture have driven China and the UK to shift away from narrowly focused farm output policies and adopt more holistic green development pathways.Second,to explore the policy objectives they have in common.Third,to assess the numerous opportunities for joint research and knowledge sharing through the Sustainable Agriculture Innovation Network and other existing institutional mechanisms.The intensification of agricultural production in the UK started several decades earlier than in China as did the negative environmental consequences of the farm practices.However,their strategies and policies for sustainable intensification and green development have much in common.These are set out in two main documents:the Chinese State Council guidelines for green agriculture and the UK Department for Environment,Food and Rural Affairs 25 Year Environment Plan.There are substantial mutual advantages from greater collaboration on problem identification and monitoring;the development of appropriate technological and management responses and the formulation of sound policies.To achieve this potential,it is recommended that further thought be given to how best to bring together all of the key stakeholders along the whole food chain.
文摘With the development of the new century,China’s agricultural modernization has reached a critical juncture.It hasbecome a matter of extreme urgency to determine which of a number of possible paths should be taken.Thetraditional way of agricultural production and development in China(and many other countries)often addresses only single.
文摘The coming century will be one of grand global challenges.We will be facing global warming,a growing world population and growing economies.To meet the needs of all world citizens in a sustainable way will not be easy.One of the challenges will be to feed the growing world population,while limiting global warming.Food and water security are at risk,and we will need to invest in innovative and clean technologies to ensure that also in the future there will be enough food to feed the word.This all is reflected in the UN Sustainable Development Goals.
文摘A recent UN Sustainable Development Goals(SDGs) analysis indicated a significant regression in the global SDG goal scores, particularly in SDG 2—Zero Hunger. The emissions of environmental pollution caused by meeting food demands have prompted some countries to intensify their climate change mitigation efforts. These circumstances have introduced significant uncertainty to the future global sustainable food development. Additionally, a notable global challenge is the persistence of hidden hunger, primarily characterized by the insufficient consumption of high-quality animal protein. Addressing this issue would necessitate increased environmental costs to attain high-quality food security. The future food system presents a significant challenge in coordinating food security, food quality and environmental quality. This article presents a comprehensive review and proposes a three-step strategy for future agricultural development based on food security, quality, and environmental aspects. This is a novel food system transfer strategy, as it concurrently addresses both global food security and environmental thresholds. It involves the construction of an efficient food system that operates within the constraints of environmental limits. The objective is to align with global SDG indicators and to maintain natural resource consumption and pollutant emissions within planetary boundaries.

文摘The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development(AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.

文摘Eco-agriculture is the principal measure for addressing the environmental issues caused by agriculture and an essential direction for agriculture in the future. Meanwhile, the development of eco-agriculture is inseparable from its technical support. At present, the eco-agricultural technologies commonly used in China can be divided into three categories according to their theoretical basis and practical types: the technologies used to realize the precision input of material resources, the technologies used to improve material circulation efficiency, and the technologies that use the principle of species symbiosis. Although these technologies provide essential support for developing eco-agriculture in China, there are also problems associated with their implementation, such as poor technical application and a low level of industrialization. Therefore, in the future development of eco-agriculture technology in China, the technologies producers should take the actual problems as guide and pay attention to the popularization, industrialization, and application of the technologies.

文摘Crop and livestock production are essential to maintain food security.In China,crop and livestock production were integrated in the past.Today,small backyard systems are still integrated but the larger livestock farms are landless and largely geographically separated from crop production systems.As a result,there is less recycling of animal manures and there are lower nutrient use efficiencies in the Chinese food production systems.This,in turn,results in considerable losses of nutrients,causing water pollution and harmful algal blooms in Chinese lakes,rivers and seas.To turn the tide,there is a need for agricultural“green”development for food production through reintegrating crop and livestock production.An additional wish is to turn the Chinese water systems“blue”to secure clean water for current and future generations.In this paper,current knowledge is summarized to identify promising interventions for reintegrating crop and livestock production toward clean water.Technical,social,economic,policy and environmental interventions are addressed and examples are given.The paper highlights recommended next steps to achieve“green”agriculture and“blue”water in China.
文摘Africa in facing numerous challenges in the 21st century in feeding its rapidly increasing population.Land resources have become limited due to urbanization and industrialization.The existing agricultural land has been degraded and soil fertility has declined due to unsustainable farming practices.Despite of progress made in the past several decades,hunger and malnutrition in Africa still hinder health,human development and economic growth,which will become even worse in the future if proper measures are not taken.Sustainable intensification is the only solution to tackling both environmental sustainability including climate change and malnutrition,i.e.,to produce more foods in terms of nutrients human body needs with less natural resources and carbon emissions.To achieve this vision,innovations in technologies,policies and institutions are essential.The Chinese experience in Agricultural Green Development(AGD)can be shared with Africans when the region is pursuing its sustainable intensification strategy.
