Soil security and global food security PERSPECTIVE

《农业科学与工程前沿(英文)》 2024年 第11卷 第2期   页码 297-302 doi: 10.15302/J-FASE-2023530

摘要:

Over the course of the postglacial period has managed to add degrade a substantial portion of the world’s potential agricultural land. The soil loss and degradation that has repeatedly impacted regional societies around the world resulted from agricultural practices that increased the physical loss of soil (erosion), reduced soil organic matter, changed pH (acidification) or salinity, and disrupted or altered communities of soil life. In the coming century, as continued soil degradation threatens global food security while the global population keeps rising it is imperative that farmers develop and adopt soil-health building (regenerative) practices to solve a problem that has plagued societies throughout history. Growing evidence suggests that agricultural systems that combine cover crops, reduced tillage, and diverse crop rotations can reduce erosion, enhance soil health and rebuild soil organic matter to cultivate beneficial soil life and harvest both economic and environmental benefits. In the coming post-oil world, global food security would benefit from a global effort to promote soil restoration to help addresses the challenge of sustainably feeding the world, increase soil-based carbon sequestration, protect on-farm biodiversity and reduce off-farm water pollution. Because soil security sets a solid foundation for global food security, agricultural policies and subsidies should be reformed to encourage farmers to adopt regenerative, soil-building practices.

Protein security and food security in China

Zheng RUAN,Shumei MI,Yan ZHOU,Zeyuan DENG,Xiangfeng KONG,Tiejun LI,Yulong YIN

《农业科学与工程前沿(英文)》 2015年 第2卷 第2期   页码 144-151 doi: 10.15302/J-FASE-2015062

摘要: Food security, the need to meet nutritional requirements, and four main problems for food protein security in China are analyzed. From the perspective of residents’ nutritional requirements and balanced dietary patterns, the conclusion is that food security in China is in essence dependent on protein production and security of supply and that fat and carbohydrates supply in China can reach self-sufficiency. Considering the situation of food protein production and consumption in China, policy suggestions are made, which could ensure a balanced supply and demand for food protein and food security in China.

Promoting green transformation by ensuring food security while reducing the environmental footprint offood and farming with agriculture green development EDITORIAL

《农业科学与工程前沿(英文)》 2024年 第11卷 第1期   页码 1-4 doi: 10.15302/J-FASE-2024549

摘要:

Reconciling the challenges of producing adequate amounts of nutritious food for the increasing global population while limiting environmental damage that can result from operations of our food systems is an enormous challenge. In many parts of the world, agriculture is undergoing major transformations and this has been and still is particularly the case in China. In many countries, historical increases in food production have largely been achieved by increasing inputs of a range of resources, resulting in increased environmental footprints of the food produced. Agricultural development in China has resulted in unprecedented environmental degradation. Demand for food in China remains high and with an emphasis on national self-sufficiency in production of many food crops. There is an urgent need for the development of productive and more environmentally-friendly agricultural systems and improved environmental-economic-social resilience.

摘要: China's food security has a great influence on the world, and has always been the top priority in China. In recent years, as the concept of food security is evolving into one of nutrition security and the importance of food diversity is increasing, research based on nutrition security and broad food systems are increasingly needed in today’s China. Thus, not only grain for human consumption, but also animal foods have been integrated into the Food Equivalent, which is used to analyze China’s current agriculture system and reveal the water resource distribution. The results indicated that the average animal food consumption has risen by 78.6%, and now China’s daily supply of animal food per capita has reached about 50% of that in the USA and 80% of that in the South Korea. So there exist an obvious disparity in animal food supply between China and these two countries. It is impossible for the China’s current agricultural system to achieve the level in the USA. Under China’s current agricultural system, the consumption proportion of feed grain had surpassed the consumption of food grain, increased sharply from 33% in 1992 to 67% in 2011. However, the growth potential of total grain output is approaching an upper limit, so the continued growth of feed grain demand exerts great pressure on the China’s food supply. The discordance of the spatial distribution of water resource and virtual water revealed that China’s current agriculture system had a low efficiency in being able to achieve food and nutrition security. China’s current “grain farming” cannot meet the demand of increasing nutrition and appropriate resource utilization. The implementation of grassland agriculture appears feasible and necessary for saving feed grain, providing a large number of high-quality animal foods and appropriate water resource utilization.

Water, energy and food interactions–Challenges and opportunities

Gustaf OLSSON

《环境科学与工程前沿(英文)》 2013年 第7卷 第5期   页码 787-793 doi: 10.1007/s11783-013-0526-z

摘要: Water and energy are inextricably linked, and as a consequence both have to be addressed together. This is called the water-energy nexus. When access to either is limited, it becomes obvious that it is necessary to consider their interdependence. Population growth, climate change, urbanization, increasing living standards and food consumption will require an integrated approach where food, water and energy security are considered together. In this paper we examine water, energy and food security and their couplings. The nexus also creates conflicts between water use, energy extraction and generation as well as food production. Some of these conflicts are illustrated. It is argued that there is an urgent need for integrated planning and operation. Not only will better technology be needed, but also better integration of policies, organizations and political decisions.

Soils for food security EDITORIAL

《农业科学与工程前沿(英文)》 2024年 第11卷 第2期   页码 213-215 doi: 10.15302/J-FASE-2024569

摘要:

Food security is among the most fundamental of national interests and productive farmland is essential for secure grain supply. With the increase of agricultural intensification and the impact of global climate change, the soil in the earth is facing various degradation problems such as compaction, acidification, and salinity. Such soil degradation is usually caused by inadequate or excessive fertilizer input and insufficient litter return to boost soil organic matter, resulting in food insecurity and a need for more sustainable management. Thus, improving soil quality or health is foundational for sustainable crop production, provide greater internal capacity to reduce external input and resistant to environmental changes. As soil is a complex and multicomponent system, the effect of single practices on soil quality are limited and systems engineering by incorporating various innovations and practices to improve soil quality and crop yield is required. Therefore, it is imperative to demand holistic research from multiple disciplines to minimize soil degradation while simultaneously promoting soil health and crop production.

In recent years, China has experienced an alarming scale of loss and deterioration of arable land. The total area of farmland has declined from 135 Mha in 2009 to 128 Mha in 2019, with a 5.6% decrease in only 10 years. Also, more than two thirds of the farmland consist fields producing only low to medium yields as they are affected by various soil degradation problems including compaction, salinization, and acidification. Therefore, protecting or preserving the farmland is an essential task in China to meet the demands of food self-sufficiency. This special issue of 8 articles presents the substantive progress that China has made in remediating soil degradation and improvement of farmland quality. The regenerative solutions for rebuilding fertile soils and developing a framework for improving soil health are discussed.

Developing a new agenda for increased food and climate security REVIEW

《农业科学与工程前沿(英文)》 2024年 第11卷 第1期   页码 35-54 doi: 10.15302/J-FASE-2023514

摘要:

In many countries, political and environmental pressures are currently combining to generate a perfect storm of circumstances that is reducing food availability, increasing food costs and thereby reducing the availability of food to many. The UK is currently considering new national food and land management policies, and attention is also being given to legislation to address diet-related health issues. Many now argue for a revolution in UK farming practices to reduce their impact on the natural environment. The UK is not alone in facing these and other challenges. Both the contribution of agriculture to greenhouse gas (GHG) emissions and the effects of climate change on food production are issues receiving worldwide attention. Regenerative agricultural practices can result in greater C capture, reduced GHG emissions, enhanced soil quality and enhanced biodiversity. However, it is questioned if such farming systems will be productive enough to feed a growing population with the food required for social and health benefits. To fully exploit the impact of new plant science in farmer fields, it is imperative to effectively link science to farming practices and conduct a broader conversation around the food revolution with social scientists and with the general public.

《农业科学与工程前沿(英文)》 2015年 第2卷 第2期   页码 134-143 doi: 10.15302/J-FASE-2015069

摘要: With high rates of food and nonrenewable fossil fuel consumption worldwide, we are facing great challenges in ensuring food and energy security to satisfy the world population. Intercropping, as an important and sustainable cropping practice in agroecosystems, has been widely practiced around the world. Many studies have shown that some plants can deliver high yields when intercropped with other plants. Here, we review the biological mechanisms in improving resource utilization efficiency and illustrate the practical application of intercropping in ensuring food and energy security through improving production. Identifying suitable energy plants for marginal land, land not suitable for food crops growth, is an effective strategy to acquire high production of bioenergy, thus removing competition between the use of land for food and energy. The effective application of intercropping provides a potential pathway for production of food crops and energy plants by improving resource use efficiency and resistance to environmental stress.

摘要: The challenges of how to simultaneously ensure global food security, improve nitrogen use efficiency (NUE) and protect the environment have received increasing attention. However, the dominant agricultural paradigm still considers high yield and reducing environmental impacts to be in conflict with one another. Here we examine a Three-Step-Strategy of past 20 years to produce more with less in China, showing that tremendous progress has been made to reduce N fertilizer input without sacrificing crop yield. The first step is to use technology for in-season root-zone nutrient management to significantly increase NUE. The second is to use technology for integrated nutrient management to increase both yield and NUE by 15%–20%. The third step is to use technology for integrated soil-crop system management to increase yield and NUE by 30%–50% simultaneously. These advances can thus be considered an effective agricultural paradigm to ensure food security, while increasing NUE and improving environmental quality.

摘要: The major source of energy comes from fossil fuels. The current situation in the field of fuel and energy is becoming more problematic as world population continues to grow because of the limitation of fossil fuels reserve and its pressure on environment. This review aims to find economic, reliable, renewable and non-polluting energy sources to reduce high energy tariffs in Russian Federation. Biofuel is fuel derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Other alternative energy sources including solar energy and electric power generation are also discussed. Over 100 Mt of biomass available for energy purposes is produced every year in Russian. One of the downsides of biomass energy is its potential threatens to food security and forage industries. An innovative approach proved that multicomponent fuel (80% diesel oil content for motor and 64% for in stove fuel) can remarkably reduce the costs. This paper proposed that the most promising energy model for future is based on direct solar energy conversion and transcontinental terawatt power transmission with the use of resonant wave-guide technology.
