Increased interest in environmental change issues has led researchers to consider more integrated approaches to change dynamics. This paper examines change in terms of land degradation in north-central Botswana from both biophysical and human perspectives. Although seasonal and periodic droughts were prevalent, analysis of rainfall data over the past 70 years revealed no downward trend. However, indicators of declining productivity such as soil erosion, loss of vegetation cover, and a declining groundwater table were amply evident. The GIS analysis of remotely sensed data has shown that complete vegetation recovery after drought is not taking place, particularly in the south-central part of the study area. These areas contained the highest human and livestock population densities. The local people acknowledged facing increasing resource depletion and indicated drought as the main cause. Pressures on available resources, particularly during drought periods, appeared to have impeded the regenerative capacity of the natural vegetation cover, thereby inducing land degradation. This situation may not easily be rectified because of widespread poverty and inappropriate local perceptions of the solutions. Both of these hinder the adoption of sustainable land management. 相似文献

This paper reports on European public perceptions of carbon capture and storage (CCS) as determined through six focus groups, one held in each of the UK, the Netherlands, Poland, Germany, Belgium and Spain. The development of opinion and the emergence of concerns were observed via phased exposure to a specially commissioned film providing an overview of CCS technology, its rationale and associated debates, supplemented by additional information on national energy mixes. In general there was a high level of commonality in opinion and concerns across the six countries, with only minor differences. The concerns that emerged were not allayed by the information provided. On the contrary, there was evidence of a shift from initial uncertainty about CCS to negative positions. CCS was generally perceived as an uncertain, end-of-pipe technology that will perpetuate fossil-fuel dependence. Noting the political context to CCS, we conclude that advocates will likely find the European public opinion context a challenging one in which to achieve deployment, particularly for onshore storage, except where local communities perceive real economic or other benefits to CCS. 相似文献

The use of forest land for ecotourism has been well accepted due to its ability to provide income to local people and to conserve the forest. Preparing the forest with infrastructure to attract and educate visitors has been reported of importance. This study applied Q methodology in a small rural community of the State of Puebla, Mexico, to reveal forest owners’ perceptions to build infrastructure in their forest as part of their ecotourism project. It also discloses forest owners’ underlying motives to use their forest for ecotourism. Ecotourism is perceived as a complementary activity to farming that would allow women to be involved in community development. Low impact infrastructure is desired due to forest owners’ perception to preserve the forest for the overall community well-being. 相似文献

Shortly after the implementation of a marine protected area (MPA) in Lyme Bay in 2008, inside which scallop dredging and bottom
trawling is prohibited, a socio-economic impact assessment was initiated. This article presents the initial findings from
this study. The aim was to understand the costs and benefits to fishermen and fish merchants of establishing the MPA. These
were assessed using a combination of primary and secondary data. The results indicate that the impacts of the closure differ
according to the gear type and the fishing location used by the fishermen. Static gear fishermen who fish inside the closed
area have seen changes in terms of increased fishing effort, mostly because they have been able to increase the number of
crab and whelk pots they deploy. The effects of the closure on static gear fishermen who fish outside the closed area has
been reported in terms of increased conflicts with towed gear fishermen who now fish regularly in their traditional grounds.
Fishermen using towed gear on the other hand have been impacted through displacement effects as they have been forced to look
for other fishing grounds outside the closed area. Most fish merchants and processors initially claimed that they were heavily
impacted by the closure but when they were interviewed 1 year after the closure they suggested a more stable picture. Preliminary
analyses of landings data indicate that the introduction of the MPA has so far had minimal impacts on the average incomes
and financial profits of fishermen and fish merchants. This conclusion, however, reflects a short-term view as the impacts
of the closure of Lyme Bay are likely to be felt for a long time to come. 相似文献

Local people's perceptions as decision support for protected area management in Wolong Biosphere Reserve, China 总被引:5,自引:0,他引:5
This paper examines local people's knowledge, attitudes and perceptions towards Wolong Biosphere Reserve (WBR) and its management policies. Pertinent data were collected through a questionnaire survey and group discussions. This study revealed that local people's perceptions were affected by many factors, including education, gender, residence location, household size and acreage of land owned. Although most respondents had limited knowledge about WBR because of their absence in WBR management, they held a positive attitude towards WBR. An in-depth analysis of their attitudes and perceptions showed that two potential conflicts might affect biodiversity conservation and protected area management. One of them was the imbalance between the limited cropland holding and the oversupply of the labor force, and the other one was the increase in electricity price versus the decrease in economic incentives for the Natural Forest Protection Project. The study also revealed that relocation was considered unacceptable to most respondents. However, those residing far from the main road were willing to relocate more than those near the main road. Based on our studies, some recommendations are given for improvement of WBR management. 相似文献
