Transgenic technologies in cassava for nutritional improvement and viral disease resistance: a key strategyfor food security in Africa

Maliwan NACONSIE,Peng ZHANG

《农业科学与工程前沿（英文）》 2016年第3卷第4期页码 285-294 doi: 10.15302/J-FASE-2016119

摘要： As a major staple food source in Africa and other tropical developing countries, cassava ( ) provides basic sustenance for many subsistence farmers. However, cassava roots mainly accumulate starch with limited contribution of other nutrients such as proteins and vitamins. Also, two viral diseases, cassava mosaic disease (CMD) and cassava brown streak disease (CBSD), cause great losses in cassava production in sub-Saharan Africa and the Indian sub-continent. Genetic engineering provides promising approaches to improve nutritional value and increase resistance to viral diseases in cassava. This report presents several successful case studies on engineering protein content by overexpression of nutritious storage proteins and improving cassava resistance to viral diseases by RNA interference. Perspectives on the sustainable acquisition of new knowledge and development of biotechnology to solve these bottlenecks are discussed.

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.

China’s new problems of food security revealed by the Food Equivalent Unit

Huilong LIN,Ruichao LI,Cangyu JIN,Chong WANG,Maohong WEI,Jizhou REN

《农业科学与工程前沿（英文）》 2014年第1卷第1期页码 69-76 doi: 10.15302/J-FASE-2014023

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.

《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.

《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.

Managing nutrient for both food security and environmental sustainability in China: an experiment for

Fusuo ZHANG, Zhenling CUI, Weifeng ZHANG

《农业科学与工程前沿（英文）》 2014年第1卷第1期页码 53-61 doi: 10.15302/J-FASE-2014006

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.

Biofuels and food security

Dmitry S. STREBKOV

《农业科学与工程前沿（英文）》 2015年第2卷第1期页码 1-12 doi: 10.15302/J-FASE-2015052

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.
