Shortfalls in global food production, coupled with the growing visibility of climate change's disruptive effects, have underlined for many observers the importance of devoting rural lands to their ‘optimal’ use, where they can make maximal contributions to the global imperatives of feeding the human population and maintaining vital environmental services. In this context observers have endorsed rural land use planning as a way to insure that, at least in theory, lands get devoted to their best uses. In practice, land use planning in the developing world has resembled ‘organized anarchy’. Small landholders with insecure land tenure, overseas investors seeking large land deals, NGOs representing indigenous peoples, government officials, and staff from international environmental NGOs and multilateral organizations have come together in strategic action fields to struggle over and sometimes negotiate land use plans for contested landscapes. These plans represent a strategic, spatially explicit response to the climate change–biodiversity–food security crisis. 相似文献

This research aims to study the origins of consumers' usefulness perceptions through the example of mobile online shopping adoption in Europe. The results of an empirical study, which is grounded in technology acceptance theory, reveal the pivotal role of consumers' beliefs about the quality of mobile online stores in the formation of usefulness perceptions prior to adoption. While this study identifies that consumers form their usefulness evaluations depending on the respective shopping tasks, the results of a moderation analysis yield usefulness predictors that differ in relevance across product categories and shopping touchpoints. This contextual perspective has implications for both adoption and (online) channel research. It also helps managers to identify starting points on how to promote (mobile) online shopping adoption. 相似文献

Technology advances enable people to trade and sell their own travel products, which in turn create numerous transformation changes into the tourism industry structure, the nature of tourism products and experiences, the competitiveness of traditional and new tourism players and the process creating (social) value in tourism. This paper investigates the application and implications of collaborative commerce in tourism and provides suggestions for future research. 相似文献

An increasing number of households are equipped with Internet-enabled televisions (IETVs) that yield opportunities for online activities. This research contributes by investigating the motivational factors of consumers’ attitudes and intentions toward IETV shopping. A quasi-experimental study in the environmental context of a living room was designed to explore IETV shopping behavior. Findings indicate that utilitarian motivations are determined by characteristics of technology and hedonic motivations from the physical environment. Attitudes toward IETV shopping are primarily influenced by hedonic shopping motivations. Conclusions suggest that by providing an IETV shopping app, retailers would make online shopping more enjoyable and comfortable for consumers. 相似文献

Soil is a natural resource essential to human welfare by virtue of its numerous crucial functions. In the past, soil has been taken for granted because of its widespread, albeit finite, availability. However, now that world's population is projected to exceed ten billion before the end of this century, soil is increasingly perceived as a precious commodity. Consequently, soil is increasingly under pressure by rich private investors and governments within the poorest countries to satisfy appetites for food production and biofuel. A case study is used to explore the plausibility of soil being considered as ‘brown gold’. Based on the comparison of land use maps, we estimated the value in terms of resource from raw material, carbon sink and virtual calories of the productive soil lost during the period 2003–2008 in the Emilia-Romagna Plain, one of the most productive areas of Italy. More than fifteen thousand hectares of cropland underwent land use change – in particular urbanization – over the 6-year period with an implied loss of crop production potential equivalent to the daily calorific requirement of more than 440,000 people. Taking into account that Italy is no longer self-sufficient in food production, such a loss appears to be strategically significant. Perhaps more importantly, urbanization and soil sealing has had negative ramifications on environmental sustainability, on both local and broad scales, with increased consumption of public funds. A logical framework of the socio-economic impact of land use change has been compiled and is presented as a possible example of a policy relevant approach to managing productive soils as a finite resource. 相似文献

中国在现代化进程中面临着一些现代性问题的困扰,其中,贫富分化成为社会矛盾的焦点之一。改革开放以来,中国居民生活水平得到整体提升,但也出现了结构上的分化。造成贫富差距的原因是复杂多重的。其中,城乡二元体制造成了城乡资源分配不公和收入差距,垄断行业的存在则使得资源在少部分群体中集聚,加深了贫富之间的鸿沟。此外,中国的社会保障制度没能充分发挥其调节作用,使得部分底层群体无法解决温饱问题,造成"极贫"群体的出现。值得关注的是,单位体制下的既得利益者,在住房制度改革后又获得福利性住房,住房不公平由此产生财产不公平。国家对于不断拉大的收入差距主要采取宏观政策加以调控,改革财税制度和完善社会保障同时进行,但这并不能因此改变由城乡二元体制和垄断等所带来的必然结果,因而只能起到局部调节收入差距的效果,不能实现真正的社会公正。 相似文献

It is generally believed that tenure security has improved due to the programme of land certification. In this paper I argue the opposite. Tenure security concerns three different rights: possession, renting and latent rights. Rights of possession are believed to have improved, but the evidence is weak and conflicting. Land rentals are expanding and farmers face high tenure insecurity. The main problem, though, is latent rights, with great insecurity and increased conflict levels. Despite rapid economic development there is considerable social malaise, an unfortunate agricultural structure, and considerable pressure for land redistribution due to unresolved land tenure issues. The paper is based on the certification literature and primary material from North Shäwa. 相似文献
