Climate change adaptation refers to altering infrastructure, institutions or ecosystems to respond to the impacts of climate change. Least developed countries often lack the requisite capacity to implement adaptation projects. The Global Environment Facility’s Least Developed Countries Fund (LDCF) is a scheme where industrialised countries have disbursed $934.5 million in voluntary contributions to support 213 adaptation projects across 51 least developed countries. But how effective are its efforts—and what sort of challenges have arisen as it implements projects? To provide some answers, this article documents the presence of four “political economy” attributes of adaptation projects—processes we have termed enclosure, exclusion, encroachment and entrenchment—cutting across economic, political, ecological and social dimensions. Based on extensive field research, we find the four processes at work simultaneously in our case studies of five LDCF projects being implemented in Bangladesh, Bhutan, Cambodia, the Maldives and Vanuatu. The article concludes with a discussion of the broader implications of the political economy of adaptation for analysts, program managers and climate researchers at large. In sum, the politics of adaptation must be taken into account so that projects can maximise their efficacy and avoid marginalising those most vulnerable to the impacts of climate change.  相似文献

ABSTRACT

This article examines the role of India’s states in shaping the implementation and framing of social policy within India’s federal system. Since the 2000s, the central government has overseen a substantial expansion of social welfare policies partly through a new push toward rights-based social provision. Yet, it is India’s states that are both responsible for an increasing proportion of total public expenditure on social welfare provision as well as determining the nature and effectiveness of that provision across space. Drawing on a comparative research program across pairs of Indian states, three critical factors explaining how state-level political environments shape social policy are identified: the role of policy legacies in shaping policy frames; the role of social coalitions underpinning political party competition; and the role of political leaders in strengthening state capacity to achieve program goals.  相似文献

Crime victim–police interface and registration of crime are the early and fundamental interactions in the criminal justice system. The process of lodging a complaint is marked by the pain of victimization, sharing of information, and expectation of quick remedial action from the police. The nature and quality of experience of the victim and outcomes impact the level of satisfaction with services of police. Through a survey of victims of property crimes, in different areas of a state in India, the author examines the impact of procedural justice and outcomes on victim satisfaction. The study illuminates the outcome oriented expectations of the victim, and the unique dynamics of victim–police interaction, which strains the legal ethical framework of the criminal justice system.  相似文献

Since the mid-twentieth century, elite political behavior in the United States has become much more nationalized. In Congress, for example, within-party geographic cleavages have declined, roll-call voting has become more one-dimensional, and Democrats and Republicans have diverged along this main dimension of national partisan conflict. The existing literature finds that citizens have only weakly and belatedly mimicked elite trends. We show, however, that a different picture emerges if we focus not on individual citizens, but on the aggregate characteristics of geographic constituencies. Using biennial estimates of the economic, racial, and social policy liberalism of the average Democrat and Republican in each state over the past six decades, we demonstrate a surprisingly close correspondence between mass and elite trends. Specifically, we find that: (1) ideological divergence between Democrats and Republicans has widened dramatically within each domain, just as it has in Congress; (2) ideological variation across senators’ partisan subconstituencies is now explained almost completely by party rather than state, closely tracking trends in the Senate; and (3) economic, racial, and social liberalism have become highly correlated across partisan subconstituencies, just as they have across members of Congress. Overall, our findings contradict the reigning consensus that polarization in Congress has proceeded much more rapidly and extensively than polarization in the mass public.  相似文献

To what extent do partisan media sources shape public opinion? On its face, it would appear that the impact of partisan media is limited, given that it attracts a relatively small audience. We argue, however, that its influence may extend beyond its direct audience via a two‐step communication flow. Specifically, those who watch and are impacted by partisan media outlets talk to and persuade others who did not watch. We present experimental results that demonstrate this process. We therefore show that previous studies may have significantly underestimated the effect of these outlets. We also illustrate that how the two‐step communication flow works is contingent upon the precise composition of the discussion group (e.g., is it consistent of all fellow partisans or a mix of partisans?). We conclude by highlighting what our results imply about the study of media, preference formation, and partisan polarization.  相似文献

A number of studies have shown that arts and cultural programs offer multifarious benefits to individuals and communities. However, there has been little discussion in the public management literature regarding access to cultural programs for people with limited disposable income. Although the arts industry is increasingly emphasizing the importance of expanding cultural access for all, we know little about what drives individual nonprofit organizations’ strategies. This article draws on benefits theory and resource dependence theory to explore the relationships between different types of revenue and the extent to which performing arts nonprofits offer free access. The authors use a unique data set compiled by DataArts to test how various types of revenue influence accessibility to the arts and find that performing arts nonprofits receiving grants from local governments, foundations, and corporations offer more free access. The article concludes with a discussion of study implications and an application of benefits theory to other types of nonprofits.  相似文献

Abstract

This paper compares the reasons given by three South-east Asian states (Laos, Thailand and Vietnam) for choosing to suppress opium production. While external pressure, often from the US or United Nations (UN)/League of Nations, is the most commonly identified reason in the literature, and was experienced in each case, it was not by itself sufficient to motivate states into action. All three cases were motivated by religious or ideological opposition to drug consumption or trade, rural development, state extension and concern for increasing domestic drug consumption. Apprehension about rising drug consumption often possessed racial or chauvinistic elements. The development of export commodities, environmental protection and national security were also identified in one or two cases. The paper concludes by hypothesising that economic and/or security considerations underlie all choices to suppress illicit drug crops.  相似文献

From January 2015 to December 2017, approximately 1.6 million migrants crossed the Mediterranean to reach Europe. The death toll was dramatic, with almost 15,000 drowning. In response to the void left by the ending of the Italian-led Mare Nostrum mission, several non-governmental organizations (NGOs) launched their own search and rescue (SAR) operations, rescuing over 110,000 migrants. In this article, we argue that states have the responsibility not only to coordinate, but also to directly provide adequate SAR operations in the Mediterranean, and that these responsibilities are presently being abdicated. Although much criticism of NGO maritime rescuing operations is misplaced, non-governmental SAR has notable limitations, and states are ultimately responsible for this shortfall.  相似文献

This article develops and elaborates on three core points. First, as with research into other social science themes, it is argued that it is necessary to apply the logic of correlation and causality to the study of political violence. Second, it highlights the critical disjuncture between attitudes and behaviors. Many or most individuals who support the use of political violence remain on the sidelines, including those who sympathize with insurgents in Afghanistan (reportedly 29 percent in 2011), and those supportive of “suicide attacks” in the Palestinian Territories (reportedly reaching 66 percent in 2005). Conversely, those responsible for such behaviors are not necessarily supportive of the ostensible political aims. Third, it is argued that the motives that drive these attitudes and behaviors are often (or, some would argue, always) distinct. While the former are motivated by collective grievances, there is substantial case study evidence that the latter are commonly driven by economic (e.g., payments for the emplacement of improvised explosive devices), security-based (i.e., coercion) and sociopsychological (e.g., adventure, status, and vengeance) incentives. Thus, it is necessary for the research community to treat attitudes and behaviors as two separate, albeit interrelated, lines of inquiry.  相似文献
