The effectiveness of incentives in protected area management: An empirical analysis

Incentive approaches are believed to be indispensable for effective conservation and successful management in protected areas. However, the actual effectiveness of these approaches is still debatable. We carried out a case study in Wolong Biosphere Reserve (WBR), the largest reserve for the giant panda (Ailuropoda melanoleuca), to evaluate the effectiveness of incentives. We obtained data from government documents and statistics, interviews and surveys on the employment status of public sector and industries. Results indicated that government-paid community-based conservation projects provided the most widespread and direct economic incentives. The conservation sector and several industries including hotels, hydropower and tourism have directly raised the employment level of local communities. The hotel industry, driven by the development of tourism, has been the most effective means of increasing local employment. However, the problem of immigrants attracted by the improved economic situation in WBR should be considered in the management plans. Suggestions for WBR management include development of quality ecotourism, vocational education for local young adults and new policies encouraging employment of local labour, both in the reserve and outside. Lessons learned from this research are constructive for the management of other protected areas.     

Sustainable development as freedom

There has been considerable debate about how best to define sustainable development. In this commentary, I argue that Amartya Sen's concept of 'development as freedom' is the appropriate theoretical framework for understanding sustainable development. Environmentalists should consider defining their goal as 'sustainable development as freedom,' the achievement of the greatest possible level of freedom without restricting the access of future generations to these same freedoms. The adoption of this framework has implications for the work of environmental NGOs, which are briefly discussed.     

Preliminary study on effects of tourism on Mosuo matriarchal culture

The ethnic communities of Lugu Lake have experienced the rapid development of tourism because of the attractions of their culture and traditional customs as well as their beautiful environment. Tourism and other economic activities have a variety of socio-cultural effects on host communities. Based on a survey of 105 Mosuo families, statistic correlation analysis was used to examine the local people's viewpoints regarding marriage, language, traditional dress, diet, and factors which could lead to changes in people's opinions. The results show that although Mosuo people are more open to the outside world, Axia relationships and matrilineal families still dominate their life. More than 50% of interviewees have Axia relationships and live in matrilinear families. Tourism income, education and age are three important factors that impact on local people's viewpoints regarding their culture and life. People who are more educated and earn more money from tourism prefer traditional culture and customs. The younger generation is more likely to be affected by tourism because they have contact with the outside world more often in their everyday life. Further research is needed on how to protect the local culture from the boom in tourism, as well as how to minimise its influence on local residents.     

Sustainable shrimp fishery management recommendations for a coastal lagoon in Baja California Sur,Mexico

The Baja California Peninsula is considered México's most productive in terms of commercial fisheries. Very few quantitative assessments of the economic importance of this region exist, especially considering artisanal fisheries and their relationships with ecological data. Datasets from government records on shrimp capture in Magdalena Bay, an arid coastal lagoon of Baja California Sur were collected, analysed and correlated with ecological data. Over the 10-year period analysed, fisheries from Magdalena Bay made up 27.5% of the shrimp capture of the state, contributing over US$15.5 million to the economy of the country. The impressive value of this resource warrants considerable attention in the design of land-use plans for the future of the region. Analysis of ecological and economical data on shrimp fishery activities in the Magdalena Bay region enables us to propose recommendations to enhance the sustainable development of the local inhabitants. A thorough assessment of the potential value of alternative economic activities should be conducted to determine their potential to provide similar productive use of the natural resources of the region as the shrimp fishery. Also, from a more specific management viewpoint, harvest rates of small shrimp in the channels should be reduced.     

Integrated effects of slope aspect and land use on soil nutrients in a small catchment in a hilly loess area,China

This study addressed the integrated effect of slope aspect and land use on soil nutrients in a loess hilly catchment in the western Loess Plateau of China. Soil samples were collected from five land-use types: wasteland, cropland, woodland, shrubland and abandoned cropland, at two depths (0–20 and 20–40 cm) in the middle slope position of both north-facing and south-facing slopes. Soil nutrient changes and the relationships between soil nutrients and slope aspect were investigated, based on statistical analysis and expert knowledge. Soil organic matter, total N, total P, nitrate nitrogen and available K of the 0–20 cm soil layer differed significantly between land uses and slope aspects. Soil nutrients in the north-facing slope were better than in the south-facing slope. Revegetation has an enrichment effect, especially on soil organic matter, total N, total P, nitrate nitrogen and available K. Planting of trees, shrubs and grasses could improve soil fertility and favours a policy of revegetation and sustainable land use in the hilly loess area of China. Conversion of slope farmlands into more sustainable land uses, such as shrubland or grassland is a cost-efficient way to achieve soil conservation and ecological restoration. Terracing and the use of agro-techniques for soil conservation, such as furrow-ridging tillage and leaving crop residues on fields, can increase the input of C to soils. Growing crops in rotation with alfalfa and beans could be a promising choice for the sustainability of agriculture and the environment.     

Socio-environmental co-evolution: some ideas for an analytical approach

A number of scholars, mainly in ecological economics, have been attracted to the concept of co-evolution for the analysis of socio-environmental change. Yet none has adopted and developed an applied analytical approach using an explicitly evolutionary framework. This paper discusses how other scholars in economics, technological studies, organization and political science have been using evolutionary explanations and draws some lessons for ecological economics. Evolutionary is a mode of explanation based on the selective retention of renewable variation. It accounts for phenomena of structural fit and change in a variety of domains. A co-evolutionary explanation, by extension, entails two or more evolving systems whose interaction affects their evolution. Socio-environmental co-evolution involves human systems (material practices and non-material ideas and values) and non-human systems (living and physical). The challenge then is how to develop case-specific, empirical applications that define and elaborate the variants that co-evolve and specify the processes of mutual selection. Applications could benefit from existing classifications and causal propositions in the natural and social sciences. Co-evolution is part of a larger analytical toolkit for looking at complex socio-environmental problems. Although distinct, there are strong synergies, complementarities and potential for combined uses between co-evolutionary, co-dynamic and complexity-based explanations.     

Principles and processes for enhancing sustainable rural livelihoods: Collaborative learning in Uganda

Livelihood diversification is essential to food security and improved incomes for human development in African rural communities. Uganda's agrarian economy suffers from limited diversification, environmental degradation, low incomes, and multifaceted negative impacts of AIDS. Efforts to stimulate and support innovation in agricultural production technology, forms of social organization, and poor markets are essential elements in promotion of sustainable rural livelihoods. Iowa State University's Center for Sustainable Rural Livelihoods and its partner organizations are applying a multi-dimensional approach to engage Uganda farmers and rural leaders in community-based learning and capability strengthening. We describe the role played by livelihood diversification and explore the promotion of sustainable livelihoods through scholarship with praxis. Sustainable livelihoods concepts are examined as a means to better understand contemporary African rural development. We identify principles and processes critical to achieving sustainable livelihoods. Their application is highlighted based on our early collaborative experience, including a discussion of the complexities associated with entering into balanced partnerships required for a successful community-based program. We explore the value of social science perspectives and processes for strengthening rural development in developing countries.     

A sceptical vision of the environmental Kuznets curve: The case of sulfur dioxide

The aim of this paper is to check the hypothesis for the environmental Kuznets curve for sulfur dioxide. This involved analysis of: 1. the theoretical basis of the model; 2. the technical problem of SO2 generation; 3 the kind of information used in the estimations; 4. changes in the structure of electric energy production; 5. improvements in energy efficiency; and 6. the recent introduction of cleaning mechanisms in a favourable political context. The conclusion is that, if it is possible to prove the existence of environmental Kuznets curve models, their utility as instruments of economic policy is debatable.     

Sustainable consumption American style: Nutrition education,active living and financial literacy

The 1992 Earth Summit highlighted the critical role of consumption in affluent nations as a source of global environmental deterioration. While most developed countries have begun over the past decade to grapple with the difficult challenges of reducing household demand for energy and materials, sustainable consumption has yet to attract substantive attention in the United States. There exist, however, several strategic openings that American proponents of more environmentally benign household provisioning could exploit to launch a public dialogue about the environmental implications of contemporary consumption. First, public health professionals have in recent years begun to make significant strides publicizing the nutritional inadequacy of the American diet and the contributory role it plays in elevating incidences of chronic disease. Second, the rapid increase in the rate of obesity in the country is now coming to be understood as a health problem that is attributable to the prevalence of sedentary lifestyles. Finally, there is growing public concern in the United States over the accumulation of unprecedented levels of consumer debt and the epidemic of personal bankruptcies. The intent of this paper is to highlight the need to consider the personal dimensions of everyday life when formulating strategies to foster more sustainable consumption.     

Malaysian households' drinking water practices: A case study

Malaysia has abundant water resources and adequate rainfall and yet the nation has water shortages and water quality problem. Various measures have been taken by the government to address water issues but, in spite of these, quantity and quality of drinking water is still one of the main concerns of Malaysian consumers today. An exploratory study was undertaken to determine the level of awareness of respondents on water issues, assess their perception on drinking water quality, and identify measures undertaken by households to improve drinking water quality and to determine sustainable water practices. A cross-sectional research design, utilizing a survey was conducted among urban residents of Seremban town. Data showed that each household had a mean of five members, with an average household income of RM3788.00 (US$1000). The respondents were Chinese (70%), Indian (23%) and Malay (7%). The majority of respondents rated the quality of water supplied to their house as poor (70%), while 16% rated it very poor. The respondents indicated that colour, odour and taste were the main problems with their tap water. Due to the poor tap water quality perceived by respondents, most took additional measures to improve its quality. Most (85%) purchased domestic water filters, 41% boiled water and 17% bought bottled water. The reasons for purchasing water were: concern for health, perception of poor tap water quality, and increasing water contamination and pollution in the country. Almost a quarter of respondents that had water filters mentioned the convenience because they did not have to boil water. Sustainable use of water by respondents was moderate, with a mean of 2.9 on a scale of 1 (never) to 4 (all the time). Some aspects of conservation, such as the promptness of repairing leaking pipes, planning activities to conserve water, and method of car washing could be improved. Advantages and limitations of different water technologies are discussed. Sustainable water practices are also proposed.
