[前沿资讯] New report says accelerating global agricultural productivity growth is critical 进入全文

EurekAlert!

The 2019 Global Agricultural Productivity Report, "Productivity Growth for Sustainable Diets, and More," released today by Virginia Tech's College of Agriculture and Life Sciences, shows agricultural productivity growth - increasing output of crops and livestock with existing or fewer inputs - is growing globally at an average annual rate of 1.63 percent. According to the report's Global Agricultural Productivity Index, global agricultural productivity needs to increase at an average annual rate of 1.73 percent to sustainably produce food, feed, fiber, and bioenergy for 10 billion people in 2050. Productivity growth is strong in China and South Asia, but it is slowing in the agricultural powerhouses of North America, Europe, and Latin America. The report calls attention to the alarmingly low levels of productivity growth in low-income countries, where there also are high rates of food insecurity, malnutrition, and rural poverty.

[前沿资讯] 河北石家庄 滹沱河生态修复工程效应凸显 进入全文

中华人民共和国农业农村部

滹沱河被誉为石家庄的“母亲河”。自20世纪七十年代中期以来,滹沱河出现断流,土地沙化严重,逐渐变成了一条垃圾带。把滹沱河修复好、利用好、发展好,是石家庄人的美好夙愿。从2017年开始,石家庄市启动了规模大、范围广、标准高的滹沱河生态全面修复工程,对全长109公里的修复工程分三期进行建设。从生态治理到景观打造,再到产业规划和行洪安全设计,一同进行修复提升。根据不同地块土质情况,确定不同配比的施肥方案,并在改良后的土壤上栽植绿植,有效缓解滹沱河两岸土地沙化问题,形成有效的生态循环。除了改良土壤改善沿岸生态外,在滹沱河的河道修复中,尽量减少使用混凝土材料。除了受冲刷严重的溢流堰,其他建筑物包括河道防护等,都采用钢丝石笼方法,尽量减少对河道的污染,努力把滹沱河打造成一条生态河。据专家计算,滹沱河生态区绿地植被形成规模后,预计每年可吸收二氧化硫2370吨,吸收二氧化碳6.2万吨,释放氧气4.5万吨。

[前沿资讯] 十年来浙江省土壤肥力稳中向好 进入全文

中华人民共和国农业农村部

浙江省农业农村厅近日发布的《2018年度浙江省级耕地质量监测报告》显示,浙江省耕层土壤有机质、全氮、有效磷平均含量处于较高或高水平,耕地地力水平总体较高,且近10年来地力变化趋势平稳,部分土壤肥力指标有所提升,土壤肥力稳中向好。监测数据显示,以每千克计(下同),浙江省耕层土壤中有机质、全氮、有效磷平均含量分别达到30.94克、2.23克、45.06毫克,处于较高或高水平;速效钾平均含量为102.95毫克,处于中等水平。其中,水田土壤有机质较旱地更为丰富,旱地土壤有效磷、速效钾等速效养分含量比水田高。该报告详细介绍了浙江省2018年度耕地土壤养分状况和近年来耕地质量变化趋势,全面阐述了肥料投入、种植制度、施肥方法等因素对作物产量和土壤养分的影响。通过合理施肥、秸秆还田、种植绿肥、增施有机肥、因缺补缺、土壤改良等措施,科学施肥水平稳步提高,施肥结构明显改善,有机肥用量逐年增加。该报告也同时指出,浙江省部分地区存在耕地土壤酸化、有效磷积累过快等问题。特别是旱地有效磷积累较快,对面源环境造成较大压力。因此,浙江省开始探索重点作物化肥定额制施用,创新免费测土配方服务,促进施肥结构调整,有针对性地开展土壤改良和综合培肥,切实保障耕地综合产能。

为探索建设空间资源环境承载力和国土空间开发适宜性在国土空间规划中的支撑点,分别构建以“本底——状态——效率”“限制性——优势度——开发潜力”为主线的土地资源建设开发承载力与适宜性评价思路,并初步探索其在实践中的应用,为中小尺度国土空间规划中建设用地布局和指标分配提供参考。 

[前沿资讯] Bayer committed to shaping a more sustainable food system 进入全文

AgroNews

Monheim, October 1, 2019 – Bayer welcomed farmers, academics, leading global industry experts, journalists and other stakeholders for its 2019 Future of Farming Dialogue, to engage in a collaborative discussion on the future of agriculture. Agriculture needs to feed a growing world without starving the planet. Breakthrough innovations are needed so that farmers can grow enough food for a growing world population while preserving natural resources. Under the theme “Tomorrow belongs to all of us” the event gathers speakers and participants from around 40 countries for two days of robust panel discussions, talks and interviews on issues and opportunitites facing the industry. Topics discussed include the need to find a balance between production of food and preservation of our planet; consumer demands to have a healthy diet with no negative impact on the environment; and the importance of crop protection tools for sustainable agriculture. Three ambitious commitments to address some of the most pressing challenges our world is currently facing by 2030:  1. Reduce the environmental impact of crop protection by 30 percent by developing new technologies that help farmers to scale down crop protection product volumes and enable a more precise application. 2. Reduce field greenhouse gases emissions from the most emitting crops systems in the regions Bayer serves by 30 percent.  3. Empower 100 million smallholder farmers in developing countries around the world by providing more access to sustainable agricultural solutions.

[前沿资讯] The New Government's Vision for Agriculture Transformation in India 进入全文

AgroNews

To meet the challenge of sustainably feeding 9 billion people by 2050, the agricultural sector will need to undergo major transformation. More nutritious food will need to be produced using fewer resources, bringing greater benefits to farmers and rural communities. Achieving this transformation will require new approaches and extensive coordination among all stakeholders in the agricultural system. Market-based approaches, while not the only answer, will be an important tool in the “toolbox” to drive change – providing the efficiency, scalability and market based incentives to power a large-scale effort. Crop Life India organized a one day seminar on the occasion of 39th Annual General Meeting. The seminar was divided in the four session with the inaugural session started at the 3.00 PM. Professor Punjab Singh, President National Academy of Agriculture Sciences, delivered the Keynote on the topic the role of crop protection in Food Security, giving data of usage of the crop protection pesticides etc in other countries in comparison to India. He further given the scenario of the Indian Agriculture, the plight of the farmers and the status of the manufacturers of these crop protection material in Indian Industry.  The other sessions were on the topic-Bringing innovation to the farmers; case for Regulatory Data Protection in India, Regulatory Reforms; and Global Best Practices, Fast Track Adoption of Drones Application Technology Solutions, and Ensuring Quality Inputs for Farmers.
