[前沿资讯] Columbia researcher studies how climate change affects crops in India 进入全文

EurekAlert!

Kyle Davis is an environmental data scientist whose research seeks to increase food supplies in developing countries. He combines techniques from environmental science and data science to understand patterns in the global food system and develop strategies that make food-supply chains more nutritious and sustainable. For his latest study, he focuses on India, home to 1.3 billion people, where he led a team that studied the effects of climate on five major crops: finger millet, maize, pearl millet, sorghum and rice. These crops make up the vast majority of grain production during the June-to-September monsoon season - India's main growing period - with rice contributing three-quarters of the grain supply for the season. Taken together, the five grains are essential for meeting India's nutritional needs. Davis found that the yields from grains such as millet, sorghum, and maize are more resilient to extreme weather; their yields vary significantly less due to year-to-year changes in climate and generally experience smaller declines during droughts. But yields from rice, India's main crop, experience larger declines during extreme weather conditions. "This study shows that diversifying the crops that a country grows can be an effective way to adapt its food-production systems to the growing influence of climate change," said Davis. "And it adds to the evidence that increasing the production of alternative grains in India can offer benefits for improving nutrition, for saving water, and for reducing energy demand and greenhouse gas emissions from agriculture."

[前沿资讯] 减肥减药减工技术给湖北蔬菜带来了怎样的变化? 进入全文

中国农业新闻网

民以食为天,食以安为先。为了让老百姓的菜篮子更绿色更安全,去年,湖北省组建省、市、县、示范基地四级构架的项目技术团队,在全省示范推广蔬菜“三减三增”健康栽培集成技术。湖北省2018年蔬菜“三减三增”健康栽培与加工技术协同推广计划实施。在省蔬菜重大技术协同推广团队指导和帮助下,健源绿色农业专业合作社改种了适合基地的蔬菜新优品种,采用合理的茬口栽培模式,在大棚里设置粘虫板防虫,在露地安放太阳板杀虫灯,将功能微生物溶入水溶肥中,通过喷灌或滴灌方式解决灌水、施肥的问题。截至目前,湖北省已有25.5万亩蔬菜使用“三减三增”健康栽培集成技术。通过一系列“减肥、减药、减工”措施的配套使用,蔬菜基地不仅效益提高,还均衡了市场供应。通过集成应用多抗品种、合理茬口栽培、有机肥替代化肥、病虫害绿色防控、水肥药一体化、农机农艺结合等“减肥、减药、减工”技术,据调查,这些使用“三减三增”健康栽培技术的菜地不仅经济效益明显,亩平增产90公斤以上,亩节本增收240元以上;而且还取得了较好的生态效益和社会效益。省农业农村厅二级巡视员欧阳书文介绍,接下来还将持续推进扩大使用面积。

[前沿资讯] Community knowledge can be as valuable as ecological knowledge in environmental decision-making 进入全文

EurekAlert!

An understanding of community issues can be as valuable as knowing the ecology of an area when making environmental decisions, according to new research from the University of Exeter Business School. Billions of dollars are spent on environmental management each year across the globe but the approach has largely been to focus on a single ecosystem or species. This narrow viewpoint has produced mixed results because it does not always consider the value of other information in the bigger picture. The research looked at what information would give real value to help decision making in order to achieve the best possible outcome. They examined four socio-ecological systems which represented a range of real-life environmental issues, two from fisheries and two from sustainable agriculture. Study one looked at how to maximise fish populations in an area with existing territorial fishing rights; study 2 was a project to re-stock salmon in a recreational fishery. The third study looked at pest control work within an agricultural production system and the last concerned the clearing of forest areas for agricultural use.

[前沿资讯] 2019年畜禽粪污资源化利用项目培训班在京举办 进入全文

中华人民共和国农业农村部

本网讯  近日,2019年畜禽粪污资源化利用项目培训班在京举办,全面解读畜禽粪污资源化利用法规和政策,进一步明确整县推进项目重点任务和工作要求,交流典型经验做法。培训班强调,要坚持政府支持、企业主体、市场化运作的方针,坚持源头减量、过程控制、末端利用的治理路径,发挥好中央资金的引导作用,加快畜禽粪污资源化利用项目落地,确保高质量完成“十三五”目标任务。要严格落实地方政府属地管理责任,发挥县级政府组织协调作用,积极促进农牧结合、种养循环发展,推动建立畜禽养殖污染治理、清洁能源生产、土壤地力改善相协调的工作机制。培训班要求,紧紧围绕农业绿色发展和农村人居环境整治,立足于扩大畜禽粪污产品终端利用渠道,加强项目实施监督管理,抓紧制定完善实施方案,整合使用相关项目资金,组织开展项目绩效评价,落实规模养殖场主体责任,推动建立畜禽粪污收贮运市场机制,努力开创畜禽粪污肥料化和能源化利用的新局面。

[前沿资讯] 有机肥替代化肥 让农产品更“绿” 进入全文

中国农业新闻网

经过有机肥滋养的土壤,开始焕发新的活力和生机。在今年的春播工作中,大家谈论最多的话题就是有机肥的使用。在绿色有机农畜产品示范省创建工作中,在农业生产上开展化肥农药减量增效行动,其中一项重要内容就是有机肥替代化肥。作为全省唯一的化肥农药减量增效行动整县推进试点县的西宁市湟源县,以绿色发展理念为导向,在全县粮油及蔬菜、汉藏药材生产中开展化肥农药减量增效行动,实施有机肥全替代化肥及农作物病虫害绿色防控技术试点面积19万亩(1亩≈0.067公顷),其中小麦3万亩、青稞3万亩、马铃薯2万亩、蚕豆2万亩、油菜5万亩、蔬菜3万亩、汉藏药材1万亩。在项目实施前期,湟源县农业农村部门组织种植大户、合作社成员等开展培训,就相关政策落实、生产记录填写、补贴机制、补贴数量、补贴方式等进行了详细的讲解,让种植户充分认识到开展化肥农药减量增效行动是农业绿色发展的方向,印发生产日志和生产记录手册25000余本,将不同农作物施肥量、种植时间及田间管理方法发放到每一户,极大地提高了农民对化肥农药减量增效和有机肥替代化肥技术的掌握程度和应用水平。在有机肥全替代化肥落实工作中,湟源县派出了120名农业技术指导员下乡入村开展入户技术指导,同村委会工作人员一起,确保面积落实到位、有机肥发放到位。据了解,使用有机肥成本会增加20%左右。从长远来看,西宁市将打造一批绿色产品基地、有机产品基地、知名品牌基地,提高农产品质量,增加绿色、有机农产品供给,最终在满足现代健康需求的同时,实现种植户生产农产品的优质优价。通过化肥农药减量增效行动的开展,能够提高耕地质量,改善农业生产条件,提高土壤有机质含量和耕地综合生产能力,扩大有机肥施用面积,优化农田生态环境,改善土壤理化性状,促进农业可持续发展。
