The mounting evidence for climate change has put the security implications of increased climate variability high on the agenda of policymakers. However, several years of research have produced no consensus regarding whether climate variability increases the risk of armed conflict. Many have suggested that instead of outright civil war, climate variability is likely to heighten the risk of communal conflict. In particular, erratic rainfall, which reduces the availability of water and arable land, could create incentives for violent attacks against other communities to secure access to scarce resources. Yet, whether groups resort to violence in the face of environmentally induced hardship is likely to depend on the availability of alternative coping mechanisms, for example through market transfers or state accommodation. This suggests that the effect of rainfall anomalies on communal conflict will be stronger in the presence of economic and political marginalization. We evaluate these arguments statistically, utilizing a disaggregated dataset combining rainfall data with geo-referenced events data on the occurrence of communal conflict in Sub-Saharan Africa between 1990 and 2008. Our results suggest that large negative deviations in rainfall from the historical norm are associated with a higher risk of communal conflict. There is some evidence that the effect of rainfall shortages on the risk of communal conflict is amplified in regions inhabited by politically excluded ethno-political groups.  相似文献

Abstract

The energy policy in Germany encourages an ever-greater utilization of biomass to produce biogas. But this utilization interferes on the natural resources and affects new conflicts regarding other forms of land use particularly flood prevention measures, drinking water supply and recreation. A forward-looking planning is needed to minimize these conflicts. Hence, this paper aims to derive quality and protection standards, summarized in checklists, assessing the effectiveness of different planning instruments with respect to the impact of biogas production in practice. These checklists were used in four model districts in Lower Saxony to evaluate the effectiveness of planning instruments on the regional level. The results show that the investigated Regional Planning Programmes do not contain any explicit planning statements as to the production of biomass or biogas. Specific regulations regarding potential conflict situations are mainly to be found in the respective Protected Area Regulations. However, generally the German spatial planning and sectoral planning provide options to control the production of biogas in a way that it is compatible with the majority of competing land uses.  相似文献

International trade fairs bring together agents from all over the world for a limited time period. They create a dense ecology of communication and information flows, referred to as “global buzz”. Global buzz associated with face-to-face (F2F) communication is extremely important for agents participating in these events as it generates access to developments occurring in different parts of the world. It helps to maintain and intensify existing networks, establish new networks or “trans-local pipelines” and support the development of shared attitudes and understandings. This paper aims to provide empirical evidence about the significance of global buzz in its manifold forms. Our research emphasizes the benefits that result from four sets of closely interrelated practices: (i) global knowledge exchange based on F2F interaction, (ii) exploration of market trends, (iii) problem solving and idea generation and (iv) network generation and pipeline-building in interpretative communities. The paper argues that practices of acquiring information, networking and dealing with competition differ substantially according to industry, firm and product characteristics. Our analysis of global buzz practices draws from more than 460 semi-structured interviews, which were conducted between 2004 and 2006 at seven national and international trade fairs in Frankfurt/Main, Hannover and Nürnberg, Germany.  相似文献

在东北的东部与北部边远地区女真水达达人聚居地,元朝建立了具有民族统辖特征的行政建置,初设置女直水达达等处宣抚司、女直水达达万户府,后发展为独立建置的女真水达达路,路下统辖的万户府和千户所,是一种特殊的行政机构,具有较大程度的直接统治机制,又保有一定的羁縻特点,实行“随俗而治”的统治方式。此外,蒙古统治者在占领女真水达达地区后,还设立了军事统辖机构征东招讨司,驻军镇守东北边陲。  相似文献

Despite important work in development studies on the ‘male bias in the development process’, it is generally recognized that gender and development analyses have been slow to engage with masculinities. Focusing attention on the nexus between identity and globalizing development discourses, this article explores the relationship between masculinities and development through an analysis of the gendering of water paradigms. By analysing the example of the recent Cochabamba water wars in Bolivia, and placing them in historical context, the author explores how gendered representations and language are used to downplay and upgrade particular understandings of modernity as they relate to water management, and examines the mechanisms through which specific gendered identities become associated with the most successful versions of ‘modern’ development.  相似文献

Indigenous professionalization is occurring throughout Latin America at an increasing pace as new careers open up in social development. Under what is heralded as socially inclusive neoliberalism, a "development with identity" paradigm is producing new university courses focused on indigenous issues. Influenced by discourses of social and human capital and addressing intersections of multiculturalism and development, these courses mobilize and help shape definitions of indigeneity; they also create spaces where donors and indigenous activists contest and debate understandings of development. Operating in a range of institutions, indigenous professionalization courses are led by a small elite group of academics and practitioners who move between programs and countries. Students also move transnationally. We argue that these courses, their classrooms and their curricula are intent on understanding intercultural situations transnationally, galvanizing international funding and support from bilateral and multilateral agencies as well as local and state actors. The social reproduction of indigenous professionalization is therefore transnational, yet grounded. At times, indigenous professionalization is socially reproduced by jumping scale; at other times, it works through established social and spatial hierarchies. This essay examines how indigenous professionalization is socially reproduced as a contested process through which notions of "good" and "culturally appropriate" development are constituted and consolidated.  相似文献

ABSTRACT

The role of firms in the process of regional renewal and path development is a somewhat neglected area in the existing literature. With few exceptions, the literature is mainly concerned with aggregated development paths. To cover this gap, the current study turns its attention to cross-industry innovation capability (CIIC) building in firms and discusses how conditions for innovation and learning in a region drive this process. We introduce a new concept of CIIC – that is, the firm’s ability to transform knowledge and ideas from different industries into new products, processes and systems and/or its ability to adapt existing products, processes and systems to new industries – and identify its drivers and indicators. The discussion is supported by empirical studies of firms in three Norwegian case regions that undergo the restructuring process due to the recent severe decrease in oil prices. Our empirical data demonstrate that organizationally thick and diversified regions are more favourable for firms’ abilities to develop CIIC and cross-industry innovation activity. As a result, we emphasize that future regional policies should have a stronger focus on the linkages between internal firm characteristics and regional innovation systems to contribute to the firms’ absorptive capacity for developing cross-industry innovation.  相似文献
