TRANSFORMATION OF AGRICULTURE ON THE LOESS PLATEAU OF CHINA TOWARD GREEN DEVELOPMENT

● Agriculture on Loess Plateau has transformed from food shortage to green development. ● Terracing and check-dams are the key engineering measures to increase crop yields. ● Agronomic measures and policy support greatly increased crop production. ● Increasing non-agricultural income is a key part of increasing farmers’ income. ● Grain for Green Program had an overwhelming advantage in protecting environment. Loess Plateau of China is a typical dryland agricultural area. Agriculture there has transformed from food shortage toward green development over the past seven decades, and has achieved world-renowned achievements. During 1950–1980, the population increased from 42 to 77 million, increasing grain production to meet food demand of rapid population growth was the greatest challenge. Engineering measures such as terracing and check-dam were the crucial strategies to increase crop production. From 1981 to 2000, most of agronomic measures played a key role in increasing crops yield, and a series of policy support has benefited millions of smallholders. As expected, these measures and policies greatly increased crop production and basically achieved food security; but, low per capita GDP (only about 620 USD in 2000) was still a big challenge. During 2001–2015, the increase in agricultural and non-agricultural income together supported the increase in farmer income to 5781 USD·yr^–1. Intensive agriculture that relies heavily on chemicals increased crop productivity by 56%. Steadfast policy support such as “Grain for Green Program” had an overwhelming advantage in protecting the natural ecological environment. In the new era, the integration of science and technology innovations, policy support and positive societal factors will be the golden key to further improve food production, protect environment, and increase smallholder income.     

Corporate Dividend Policy Under the Change of Earnings in China

Using non-parameter test and multinomial logit regression, this paper studies the dividend policy and behavior empirically. The results show that the change of the earnings of firms affects their dividend policy. When the EPS of the firms increase, the probability of choosing not to pay cash dividend is maximal, yet when the EPS of the firms decrease, many firms choose not to pay cash dividend or choose to increase DPS, so that the information that the relevant firms have great expectation is transmitted to the market. Furthermore, this paper also finds that the successiveness of the dividend policy of the listed firms in China is not good.     

Resolvent and Application of Policy Control for QoS

With the rapid increase of the Internet user and widely application of Web,the current network technology is facing great challenge. More and more multimedia operations occupy plenty of bandwidth,and result in the network congestion. Therefore,people begin to use QoS to utilize the bandwidth effectively,and ensure the transport of the emergent operation data. The paper introduces the protocols and basic components of QoS,then expatiates the conception and the basic principles of policy control QoS, moreover,emphasizes the structure model of policy control QoS and how it runs. At last,it introduces the transport process of data packets under the control of policies in a policy control QoS system,and how to make the policies in the real world.     

Irrigation and food security in the 21st century

Global food projections indicate that food prices in the next threedecades will likely be stable or decline, but progress inreducing malnutrition in developing countries will be slow. Smallshortfalls in crop productivity growth would lead to rising foodprices and worsening malnutrition. Increased food production fromirrigation is essential, and will require expansion of irrigatedarea and water supplies, and improved efficiency of use of existingwater supplies. Neither of these growth factors will prove easy, andboth will require complex institutional and policy reforms. Failureto meet food production needs through efficient expansion andintensification of irrigated agriculture would increase pressure onland resources and hasten the process of environmental degradation.Irrigation and water development strategies have been hampered bya lack of understanding of the links between water scarcity, foodproduction, food security, and environmental sustainability.Research to improve this understanding would have high payoffs.     

Policy options for Agriculture Green Development by farmers in China

Farmers are the key agents who manage land and water. Agriculture Green Development (AGD) requires a transformation in farming from high resource consumption and environmental cost to sustainable intensification with high productivity, high resource use efficiency and low environmental risk. This paper analyzes the public policy challenge of AGD and makes the case for a location-sensitive policy mix made up of regulation, advice provision, voluntarism and targeted incentives. The public agricultural extension service in China is a key resource, but one that requires reorientation and reform with the aim of better balancing high farm productivity with environmental protection.     

1978—2018年中国农村环境管理政策演进特征——基于206份政策文本的量化分析

基于手工搜集的1978—2018年中国政府颁布的206份农村环境管理政策文本,从政策发布年度、政策发布主体、政策发布形式、政策作用对象、政策工具及政策效力6个维度构建分析框架,运用政策文献计量和内容分析方法分析了中国农村环境管理政策的演进特征。结果表明:1978年改革开放以来,中国农村环境管理政策在数量上呈整体持续上升态势;农村环境管理政策经历了探索起步(1978—1989年)、初步形成(1990—2004年)、快速发展(2005—2013年)和全面推进(2014年以后)4个阶段的演进;政策发布主体的行政级别较高且呈现多元化特征,政策联合决策程度高,但政策之间统筹性和协调性较低;政策绝大多数以通知、意见等形式发出,缺乏权威性和规范性;政策的着力点主要在原生态保护层面,对农村人居环境整治的重视程度不够;命令控制型政策是政府最为偏好的农村环境管理政策工具,经济激励型、信息公开型和自愿参与型政策工具使用不足;政策整体效力的提升主要由政策发布数量驱动,政策反馈不足、政策措施较少和政策目标量化程度低是导致政策平均效力较低的主要原因。     

Land degradation,stocking rates and conservation policies in the communal rangelands of Botswana and Zimbabwe

Communal rangeland management policies in Botswana and Zimbabwe are based on incorrect technical assumptions about the stability of semiarid rangeland, the nature of rangeland degradation, and the benefits of destocking. Consequently, inappropriate policies, stressing the need to destock and stabilise the rangelands, are pursued. Acknowledgement of the great instability but intrinsic resilience of rangeland would encourage the Governments to more favourably regard the opportunistic stocking strategies of the agro-pastoralists of the Communal Areas. However, degradation of rangelands is occurring, although at varying rates. This justifies the promotion of a ‘tracking strategy’, in which livestock densities are encouraged to follow, more closely that at present, variations in rainfall. The establishment of grazing territories controlled by specific ‘communities’ may be a prerequisite for the promotion of the tracking strategy, and for communal rangeland management and improvement. However, the establishment of such territories must take into account social equity, institutional problems and transaction costs, as well as spatial and temporal variation in rangeland resources.     

BUILDING CLIMATE-RESILIENT FOOD SYSTEMS IN EAST AND SOUTHEAST ASIA: VULNERABILITIES,RESPONSES AND FINANCING

Food system resilience to climate change is uniquely imperative for bringing Sustainable Development Goals within reach and leaving no one behind. Food systems in East and Southeast Asia are interacting with planetary boundaries and are adversely affected by extreme weather-related events. A practical question for East and Southeast Asian stakeholders is how to foster climateresilient food systems in the face of lingering food system vulnerabilities and policy gaps. This paper reviews food syste...     

关于完善渔业油价补助政策的探讨

从对国内外渔业油价补助政策的实践来看,该政策对于稳定渔业生产发展有着重要作用。通过会议座谈、重点调查和问卷调查等方法对我国现行渔业油价补助政策进行了调研分析,认为我国渔业油价补助方法不够科学合理,不仅与现行渔业政策不协调,还暴露出实际操作比较困难、支撑渔业油价补助发放的配套制度不够健全等问题。结合我国渔业产业实际,建议应调整完善海洋捕捞业和水产养殖业的油价补贴办法、统一细化全国渔业柴油补贴扣减政策、完善渔船管理和渔政执法管理相关制度等,提高渔业油价补助决策的科学性和民主性。
