Ecotourism as a conservation tool and its adoption by private protected areas in Brazil 总被引:1,自引:0,他引:1
Ecotourism in private reserves combines the establishment of protected areas with an incentive mechanism to conserve biodiversity. Brazil's private reserve system is well-established but little is known about its links to tourism. This study puts the global private protected area into context and quantifies the extent to which ecotourism has been adopted as a sustainable land-use practice on private reserves in Brazil. Our findings demonstrate that small reserves do contribute to conservation and are used for ecotourism. The belief that large reserves are necessary for ecotourism and conservation is challenged. Only 4% (n = 45) of the 1182 reserves are engaged in ecotourism, mainly those within the Atlantic Forest biome and these are generally small in size (<50 ha). Reserves provide modest to basic accommodation as well as education and economic opportunities that include adjacent communities. Hiking and bird watching are the most popular activities but many reserves are threatened by poaching and invasive species. The low adoption of ecotourism appears due to a combination of factors, including lack of landowner interest, constraints imposed by regulations, logistics and anthropogenic threats. Nonetheless, there is potential to expand ecotourism within private reserves as 143 further private reserves are located near those already engaged in ecotourism. 相似文献

This paper starts from the stylized fact that firm size and exporting tends to be positively related. Using large sets of
establishment panel data for three different industries from official statistics, evidence is presented that the familiar
picture of an export/sales ratio that increases (at a decreasing rate) with firm size vanishes if unobserved firm heterogeneity
is controlled for in a fixed-effects fractional logit regression model. This finding is well in line with the fact that many
small firms are “hidden export champions.” JEL no. F10, D21, L60 相似文献

This paper analyzes the demand of French farmers for pesticides by disaggregating among the three main categories of pesticides. We estimate the demand elasticities of herbicides, insecticides, and fungicides with respect to pesticide expenditure, and also consider crop differentiation. We retain a Linear Approximated Almost Ideal Demand System specification. A Full‐Information Maximum Likelihood estimation procedure is used to deal with corner solution problems and censored data. The estimation is based on two cross‐sections covering pesticide use of three major crops cultivated in France in 2001 and 2006. Our results show that farmers' response to price variation is very low, especially for 2001. Furthermore, elasticities of pesticide expenditure are significantly different across categories: the highest levels are obtained for fungicides and the lowest ones for insecticides. Finally, we find higher own‐price elasticities for herbicides and fungicides than for insecticides, which are less frequently used. 相似文献

In this article, we focus on consumption in a context of economic hardship. From an empirical perspective, and using a qualitative methodology, we show how disadvantaged individuals and households maintain a level of consumption commensurate with the society in which they are integrated through a type of consumption conceived of here as “resilient”. Resilient consumption is characterized by being a type of expenditure oriented towards maintaining the role of consumer, that is, maintaining a minimum level of purchasing power, modifying to this end both the level and the structure of consumption, both of which are key elements in the resilience process. We identify five main strategies used by households that modify and restructure the consumption of basic goods and necessities in response to economic hardship. Key resilient consumption strategies include: reduction (cutting down on spending), substitution (replacement of one difficulty with another), compensation (pseudo‐consumption or reduced usage), transference (meta‐resilience) and integration (reinterpretation of difficulties as opportunities). We conclude that although consumption is a naturally resilient behaviour, in a crisis context, resilient practices focus on maintaining acquisition capacity in spite of reduced income. 相似文献

Although enterprises in the informal food sector require energy to transform, cook and process food, energy-use patterns in this sector are not well understood by policymakers and the local-level authorities who regulate their trading activities. This paper reviews relevant literature and presents empirical data collected in Rwanda, Senegal and South Africa on the use of traditional and modern energy sources by informal food sector operators. Our sample includes male- and female-operated enterprises in the urban centres of three African countries where the informal food sector is important, not only for providing the convenience of affordable and readily prepared meals, but also as a source of income for women and men in developing countries. Multiple fuel-use and energy-stacking strategies are common among informal food enterprises and policy needs to acknowledge this if it is to intervene in ways that will benefit both enterprises and regulators. 相似文献

The growing competition in the hotel industry is one of the main challenges of this segment, which increasingly depends on the ability to innovate. Thus, this article aims to analyze the impact of innovation on the performance of employees and hotel organizations. This is an exploratory study, with a quantitative approach using a structured computer-administered questionnaire to 73 managers of hotel chains, located in Brazil, which correspond to 792 hotels. Data analysis used multiple linear regression method with SPSS software to find out the relationship between the factors of innovation (communication, processes, leadership, and strategy) and the performance of employees and hotel organizations. Results show that the factors of communication, leadership, and strategy directly influence the performance of the employees. However, only the leadership factor directly affects the performance of hotel organizations. 相似文献

Since voters are often swayed more by the personal image of politicians than by party manifestos, they may cast votes that are in opposition to their policy preferences. This results in the election of representatives who do not correspond exactly to the voters’ own views. An alternative voting procedure to avoid this type of election failure is prompted by the approach implemented in internet voting advice applications, like the German Wahl-O-Mat, which asks the user a number of questions on topical policy issues; the computer program, drawing on all the parties’ answers, finds for the user the best-matching party, the second-best-matching party, etc. Under the proposed alternative election method, the voters cast no direct votes. Rather, they are asked about their preferences on the policy issues as declared in the party manifestos (Introduce nationwide minimum wage? Yes/No; Introduce a speed limit on the motorways? Yes/No, etc.), which reveals the balance of public opinion on each issue. These embedded referenda measure the degree to which the parties’ policies match the preferences of the electorate. The parliament seats are then distributed among the parties in proportion to their indices of popularity (the average percentage of the population represented on all the issues) and universality (frequency in representing a majority). This paper reports on an experimental application of this method during the election of the Karlsruhe Institute of Technology Student Parliament on July 4–8, 2016. The experiment shows that the alternative election method can increase the representativeness of the Student Parliament. We also discuss some traits and bottlenecks of the method that should be taken into account when preparing elections. 相似文献

Innovative systems and infrastructures require generally accepted common compatibility standards to enable components of such systems to interoperate. In some cases, various standards are developed by competing standards organizations, often resulting in standards battles. This paper focuses on factors that affect the outcome of these standards battles, and, specifically, on the effect of the structure of the industry-wide standards networks on standard dominance. The empirical context is the consumer electronics, telecommunications, and ICT arenas. We conduct a study of 103 standards organizations from 2000 to 2011. We find support for the hypothesis that standards that are supported by standards organizations that have a central position in the industry-wide standards network have a high chance of achieving dominance. 相似文献

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification:
