中国国土资源经济

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.

[学术文献] 基于联系数的水资源承载力状态评价模型 进入全文

河海大学学报(自然科学版)

基于集对分析和三角模糊数理论,建立水资源承载力状态评价模型。通过理论分析、频率计算和数据统计,选取14个指标,划分为5个等级,建立水资源承载力评价指标体系;采用主客观赋权相结合的方式计算各指标组合权重,分析水资源承载力的主要影响因素及其原因。在联系数方法的基础上,用减法集对势分析各样本水资源承载力态势。对山东省17个地级市2015年各指标数据进行实例分析,结果表明:影响山东省各地级市水资源承载力状态的主要因素为单位面积灌溉水量、单位面积地下水资源量、单位面积废水排放量;山东省总体水资源承载力处于临界超载和轻微超载状态,在水资源禀赋条件稳定的情况下,提高水资源利用效率,改善水生态环境,能够有效提升水资源承载力水平。 

[学术文献] An evaluation of China’s agricultural green production: 1978-2017 进入全文

Journal of Cleaner Production

Green development and low-carbon economy play important roles to achieve sustainable society. Since agricultural production is the foundation of the Chinese national economy, agricultural green production acts as the driving force in green economy development, as well as a prerequisite to realize green behavior and sustainable ecology. Different from traditional agricultural production, the idea of agricultural green production also put many factors including economy, environment, and social development into comprehensive consideration. It provides the future directions of China’s agriculture. This research aims to systematically sort the agricultural green production goals from five dimensions: supply capacity, resource utilization, environment quality, ecosystem maintenance, and farmers’ lives. An agricultural green production assessment index system was constructed based on national agricultural census data indicators. Furthermore, the gap between China’s agricultural green production status and target value, as well as the vertical and spatial evolution of agricultural green production levels in China have been determined empirically relying on the data from three national agricultural censuses and additional statistical data from national statistical yearbooks and coefficient manuals. Moreover, key recommendations were provided for path optimizing and China’s agricultural green production upgrading.
