农业是人类发展的重要基础,近年来,人口增长、环境污染加剧、食品安全问题频发,给农业生产带来了诸多挑战,绿色农业和可持续发展成为当前农业生产变革的主题。传统的通过合成化学杀虫剂和化肥防治病虫害、提高作物产量的农业生产方法,... 农业是人类发展的重要基础,近年来,人口增长、环境污染加剧、食品安全问题频发,给农业生产带来了诸多挑战,绿色农业和可持续发展成为当前农业生产变革的主题。传统的通过合成化学杀虫剂和化肥防治病虫害、提高作物产量的农业生产方法,尽管在一定时期内增加了粮食产量,但化学农药过量使用导致环境退化、土壤和水污染、出现耐药性害虫等问题,严重影响了农业的可持续发展。为了应对这些问题,人们对发展可持续农业的需求越来越迫切,而生物农药在应用中能够有效地促进可持续农业生产的发展。因此,本文对生物农药在可持续农业中的实际应用进行详细分析,希望通过生物农药的广泛应用,促使农业可持续发展得到有效落实。 展开更多

The Integrated Agricultural Systems workgroup is examining agricultural systems of the US to determine fundamental principles that underlie successful production systems. Our hypothesis is that principles are applicable across regions, but key drivers interact to influence producer decisions and create distinct production systems. We interviewed agricultural producers to examine the underlying rationale for producer decisions and discern primary factors influencing production and marketing practices. While drivers are common among regions, interactions between drivers and influences on decision-makers vary substantially to create unique production systems. The internal social driver that values farming lifestyle is the principal factor that leads people to farming. The type of farming is partly a lifestyle choice and is influenced by other factors. Economic drivers and marketing options are primary drivers influencing production systems and management choices, as farmers provide an economic foundation for their families. While all producers employed strategies to manage production and marketing risks, these varied with different marketing channels. Identification of key drivers and principles can be used by producers, scientists and policy makers to direct agricultural production and agricultural research. New management systems can be developed that are flexible enough to respond to changing societal demands, and are environmentally and economically sustainable. 展开更多

This article focuses on technology's enormous impacts in solving food security. Over the past several decades technology has made an important contribution to Chinese food production, and it will continue to have the widest impact on food security in China. The relationship between technology and environment is discussed in this article. It is suggested that technology is significantly related to the theme of sustainable Agriculture, and technology can achieve food security. 展开更多

Approximately ten years have passed since Globally Important Agricultural Heritage Systems(GIAHS)was introduced to Japan in 2011,with 11 GIAHS sites designated so far.The Japan Nationally Important Agricultural Heritage Systems(J-NIAHS),which considers resilience,multi-stakeholder participation and sixth industrialization,was subsequently established in 2016,and has designated 15 J-NIAHS sites.GIAHS sites can be classified into three major types:Landscape,farming method,and genetic resource conservation types,and most Japanese GIAHS sites are of the landscape type.Since there is almost no national subsidy for GIAHS or J-NIAHS,designated sites are expected to secure funding for conservation from their own efforts.For this reason,a voluntary network of the Japanese GIAHS sites has been active in promoting cooperation on GIAHS conservation.The priorities of the Japanese GIAHS have focused on raising public awareness about GIAHS and J-NIAHS,improving livelihoods,as well as fostering the international exchange of experience and knowledge regarding Agricultural Heritage Systems,especially among Japan,China and Korea. 展开更多
