Land tenure and land policies influence the spatial variations of land use/cover (LULC) at any given time or place. Thus, it is important to evaluate the role of land tenure policies on land cover changes. In this study, we evaluate the utility of Landsat Thematic Mapper (TM) images in understanding the impacts of the 2000 fast track land reform (FTLR) policy on LULC in the eastern region, Zimbabwe. Landsat images for the year 1995, 2000, 2005 and 2011 were classified using traditional image classification techniques (i.e. the maximum likelihood (ML) classifier) in a geographic information system (GIS) environment. Results indicate that forested areas drastically decreased by approx. 30% between the year 2000 and 2005 (during and after the FTLR), while croplands marginally increased by (approx. 30%) the results further showed that slight increase in bare lands (degraded lands) and disturbed lands. The observed LULC changes after FTLR were mostly induced by human activities resulting from changes in land tenure. Overall, the findings of this study underscores the importance of remotely sensed data in assessing the impact of FTLR on forest resources for purposes of informed and sustainable forest management. 相似文献

Coal is the major primary energy which fuels the economic growth in China. The Soviet-style institution of the coal sector was adopted after the People’s Republic was founded in 1949. But since the end of 1970s there have been major changes: the market mechanism was introduced to the coal sector and the Major State Coal mines were transferred from central to local governments. This paper explains these market-oriented and decentralized reforms and explores their implications for the power sector, now the largest single consumer of coal. The argument of this paper is that the market-oriented and decentralized reforms in the coal sector were influenced by the changes in state energy investment priority as well as the relationship between the central and local governments in the context of broader reforms within China’s economy. However, these market-oriented and decentralized reforms have not equally influenced the power sector. Even though initial coal sector reform spurred power generation, the subsequent fragmented reforms raise concern about electricity shortages. 相似文献

The goal of this article is to evaluate the impact of the drastic Spanish Penal Code reform on the number of road deaths in Spain and the time that the effects might last. This is achieved by means of multivariate unobserved component models set up in a state space framework estimated using maximum likelihood. In short, with this reform Spain might be considered to be closing the final gap that kept it apart from other developed countries as far as the road accident rate is concerned. We have found two different types of effects on Spanish road traffic fatalities. Initially, a month before the reform was passed there was a 24.7 percent fall in Spanish road deaths. After the Bill had been passed and for the following thirteen months, the reduction stayed at a constant sixteen percent. This reform has reduced Spanish road fatalities by 534 in all between November 2007 and December 2008 and the effects will foreseeably continue during 2009. 相似文献

我国历经6年的林权制度改革作为促进林业发展的根本措施,正在不断深化并已经取得很大成就。但同时也应看到其对生态环境具有一定影响(正面和负面影响)。如果国家在实施林业制度改革之前或实施初期对其可能带来的生态环境影响进行预先的评估,有利于最大程度地减少其负面影响和扩大其正面影响,将有助于决策者做出科学决策。因此开展林权改革环境影响理论与实践研究成为当务之急,是进一步开展好林权制度改革后续的配套政策措施研究的重要内容,是保障林权改革相关政策顺利实施的重要保障。为此建议:第一,国家相关部门要高度关注林权制度改革过程中对生态环境的影响;第二,应尽快深入开展林权改革环境影响评价理论与实践研究;第三,把林权改革作为重点领域开展政策环境影响评价试点,为在规划环评基础上进一步实施政策环评制度提供技术支撑,为修改《环评法》和政策环评作好技术储备,为促进林业绿色发展保驾护航。 相似文献
