稻农采用节水技术影响因素的实证分析——自然因素和经济因素效应及其交互影响的估测 总被引:4,自引:0,他引:4
本文对16个省(区、市)25个县(市、区)4686个农户采用旱耕水整、旱育秧、干湿交替灌溉及全程节水等水稻节水技术情况的调查和分析表明:农户人均收入、种稻规模、所在区域等特征因素以及年降雨量、灌溉费等自然因素和经济因素,明显影响稻农采用节水技术;灌溉费与年降雨量存在显著的交互影响;灌溉收费机制对稻农采用节水技术有显著影响。因此,构建与用水量挂钩的收费机制,可有效促进稻农采用节水技术。 相似文献

The influence of farm input subsidies on the adoption of natural resource management technologies 下载免费PDF全文

Farm input subsidies are often criticised on economic and ecological grounds. The promotion of natural resource management (NRM) technologies is widely seen as more sustainable to increase agricultural productivity and food security. Relatively little is known about how input subsidies affect farmers’ decisions to adopt NRM technologies. There are concerns of incompatibility, because NRM technologies are one strategy to reduce the use of external inputs in intensive production systems. However, in smallholder systems of Africa, where the average use of external inputs is low, there may possibly be interesting complementarities. Here, we analyse the situation of Malawi's Farm Input Subsidy Program (FISP). Using panel data from smallholder farm households, we develop a multivariate probit model and examine how FISP participation affects farmers’ decisions to adopt various NRM technologies, such as intercropping of maize with legumes, use of organic manure, water conservation practices and vegetative strips. As expected, FISP increases the use of inorganic fertilizer and improved maize seeds. Yet, we also observe a positive association between FISP and the adoption of certain NRM technologies. For other NRM technologies, we find no significant effect. We conclude that input subsidies and the promotion of NRM technologies can be compatible strategies. 相似文献

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts are incorporated into a population model, and the costs of search and control are calculated as functions of the amount of search effort (the decision variable). Simulations are performed on a set of weed scenarios in a natural environment, involving different combinations of plant longevity, seed longevity and plant fecundity. Results provide preliminary estimates of the cost and duration of eradication programs to assist in prioritising weeds for control. The analysis shows that the success of an eradication program depends critically on the detectability of the target plant, the effectiveness of the control method, the labour requirements for search and control, and the germination rate of the plant. 相似文献

This paper presents the reasons for uncontrolled land-use changes in the water resource basins of Istanbul. These changes are evaluated with a Geographical Information System (GIS), using four Landsat (1990, 1995, 2000, 2005) satellite images. Additional spatial information about capital improvement projects (highways and the Bosporus bridges), industrial land-use decisions, land ownership, and jurisdictional boundaries is also utilized. We observe that the most critical land-use changes have occurred in places with higher accessibility, mostly in close proximity to the metropolitan city center. The literature describes large public capital improvement projects (primarily the Trans European Motorway – TEM) as the primary reason for a trend of illegal occupation of public lands; however, the TEM should not be considered as the sole reason. This study explores other possible causes for these illegal developments in the water resource basins, grouped into three broad dimensions physical, socio–economic–political, and legal. Finally, we put forward possible policy suggestions for the preservation of the limited surface water resource basins in Istanbul. 相似文献

The evolution of Australia's natural resource management programs: Towards improved targeting and evaluation of investments 总被引:2,自引:0,他引:2
This paper examines the evolution of Australia's natural resource management programs over the past two decades. The story is one of major paradigmatic shifts with implications for the design and operation of similar programs worldwide. Since 1983, Australian Governments have approved the National Soil Conservation Program, the National Landcare Program, the Natural Heritage Trust, the National Action Plan for Salinity and Water Quality and a new program called Caring for Our Country. These programs have seen a transition from the early days of attitude change to the creation of new regional institutions and direct payment systems for environmental stewardship. Despite these advances recent audit reports have mirrored those from the United States and the Europe. They identify problems of ineffective targeting, monitoring and evaluation of expenditure. This paper considers the efficiency and effectiveness of alternative program designs in Australia. Two major design improvements are suggested: (a) systems for linking expenditure to outcomes and (b) adopting standardised metrics for valuing outcomes. This will permit the application of benefit-cost and cost-effectiveness analysis and, ultimately, improved returns on investment. 相似文献
