Incentives and disincentives for diversified agroforestry systems from different actors’ perspectives in Bolivia

Even though diversified agroforestry systems can provide sustainable livelihoods and a resilient production of different goods, adoption remains limited in Bolivia. We examine major obstacles to agroforestry adoption and possible incentives proposed by farmers and civil-society organizations, and relate them to governance and international mechanisms that might play a role in agroforestry adoption. Market access for produce from diversified agroforestry remains difficult, as does its processing and transport. Moreover, farmers have difficulties in achieving the quantities and homogenous quality demanded by markets in the major cities. But most importantly, farmers and civil-society organizations saw little government support, although ‘ecological production in harmony with Mother Earth’ is prescribed by law and the constitution. Agroforestry farmers needed support most urgently in the initial phase, when investment costs are high and returns low. They suggested affordable credits, subsidies for diversified farming systems, and insurance against fire. We identified important albeit small steps towards developing markets for agroforestry products, but government support – mostly in the form of diesel subsidies, materials, and infrastructure – mainly benefitted large-scale monocultures and cattle ranching. In response to this, interviewees opted for strengthening farmers’ organizations, for demanding support with the help of civil-society organizations, and for disseminating best practices.     

Will future land based food and fibre production be in family or corporate hands? An analysis of farm land ownership and governance considering farmer characteristics as choice drivers. The New Zealand case

Family farming in various guises has been the dominant ownership and governance system in primary production over recorded history. This outcome has been controlled by farmers and their families, possibly due to tradition, opportunities, personal characteristics, skill sets and the nature of primary production. Of these, it is hypothesised that the farmers’ personal characteristics play a major part in the choice, and continuance, of current ownership and governance systems. Equally as important, they, and therefore the land ownership system, play a part in the efficiency of production systems and improvement of the biological and production environment.The benefits and difficulties of commonly used ownership systems in Western society are reviewed. Using a sample of New Zealand (NZ) farms, a comparison of the managers’ features for owner/operator, partnership and corporate based systems is presented. There were significant differences in many variables including the farmers’ age, education, number of children, asset levels, years on the current farm, and similar, but more importantly, the farmers in the ownership system groups had differing personal characteristics. Significantly, despite the corporate based farms employing more professional assistance, the profit levels were similar across ownership systems leaving the farmers’ characteristics the main factors correlating with system choice. However, governance systems per se are only marginally correlated with production systems and efficiency.As successive generations of farmers are unlikely to have different characteristics, and corporate based systems continue to exhibit similar profit levels, relatively simple family based systems will continue to dominate farm land ownership and control. The trends suggest family farms will increase in size and involve family conglomerates facilitating the management of larger, and in many cases multiple, farms. While currently there are few differences in biological efficiency between ownership systems, given the efficiency benefits of size and scale, this could well change with the increase of family conglomerates. Relative to increasing corporatisation, the continuance of family based ownership and governance will also be of benefit to the environment. When developing land policies, these highlighted relationships should be taken into account. This study is a first to consider personal characteristics relative to ownership.     

Learning-by-importing in emerging innovation systems: evidence from Ecuador

Using data from the population of Ecuadorian importers, we examine the extent to which the characteristics of their imports relate to their labor productivity. Results indicate that the technological intensity of imports does not explain differences in labor productivity, although the region of origin of imports explains differences in the manufacturing sector, as imported technologies from advanced regions are associated with superior labor productivity. Nevertheless, as technology intensive imports are not associated with superior performance, we argue that importers from developing countries may use foreign technology inexpertly due to the lack of absorptive capacity and the emerging nature of their national innovation system.     

Localization and Customer Retention for Franchise Service Systems

This is one of the first studies to explore customer retention in reference to the franchisee–customer relationship. A subsequent objective was to examine localization and standardization from a franchise unit and system-level perspective. Data was collected using a self-administered survey based on customers of pet grooming services in Australia. Findings suggest that the addition of a customer retention perspective reveals a greater depth to the franchisee–customer relationship. Importantly, this implies that there are additional factors likely to influence franchisee–customer retention within franchise outlets. We suggest that individual franchise units, in cooperation with local customers, should co-create local marketing initiatives.     

After over 25 years of accrediting beaches,has Blue Flag contributed to sustainable management?

This paper examines the qualitative, quantitative, and geographical evolution (1987–2012) of the Blue Flag campaign and accreditation process in Spain, a leading coastal tourism destination heading the list of awards. The standard Blue Flag criteria for crowded, developed beaches are now adapting to new demands for natural beaches, but they still fail to capture essential sustainable tourism features, such as limiting user numbers, or preserving and restoring sand ecosystems. Given these shortcomings, some destinations are moving to alternative awards with a higher environmental commitment, such as EMS, ISO14001, and Eco-Management and Audit Schemes (EMAS). A cluster analysis of Blue Flag data for 983 beaches in Spain over 26 years revealed different behaviour patterns: established tourist areas that have always opted for the Blue Flag programme; tourist areas that adopted the Blue Flag early on but replaced it with ISO14001 and EMAS; recently developed destinations applying for the award to boost their tourism promotion; and tourist areas with no well-defined policy that have opted intermittently for Blue Flag. These profiles illustrate the different policies of Spain's Autonomous Regions, and they are useful for tourism managers to verify whether their destination's behaviour pattern contributes to sustainable tourism and matches strategic policies they have designed for them.     

Situating the wildlife spectacle: ecofeminism,representation, and polar bear tourism

This paper presents a critical investigation of power relations circulating in promotional materials associated with polar bear tourism in Churchill, Manitoba, Canada. Drawing on precepts of ecofeminism, critical discourse analysis, and the content of cultural texts (websites, souvenirs) produced by tourism operators, businesses, and crown corporations, the study interprets how representations of polar bears re-inscribe regimes of truth that marginalize non-human animal others and are complicit with patriarchal ideologies. Focus in our analysis is placed first, on illustrating the portrayal of “performing spectacle bears” – a socially constructed subjectivity designed to serve the desires of wildlife tourism producers and consumers – and, second, on diagnosing the privileged discourses that work to maintain and normalize this construction, along with the interspecies dynamics they support. In effect, the paper sheds light on the complex and recurrent effects of anthropocentric and instrumentalist orientations in tourism, including their contingency upon masculine systems of value and rationality. The paper also points out the potential of ecofeminist ethics of care for enhancing interspecies relationships in sustainable tourism.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.
