We conduct an experiment to determine competitiveness among shrimpers who engage in collecting shrimp seeds in the southwestern coastal region of Bangladesh. We then examine how competitiveness affects the labour supply decisions and labour market performance of these shrimpers. Our results show that shrimpers who prefer competition are more productive than shrimpers who do not prefer competition. Competitive shrimpers secure better prices and earn higher incomes selling their catches. We estimate that their wage elasticity of participation ranges from 0.4 to 0.5, which is consistent with preferences under neoclassical assumptions. Competitive shrimpers have a slightly greater wage elasticity than non-competitive shrimpers, suggesting that they might be more responsive to expected earnings. Our results have important policy implications for the efficient management of common pool resources.  相似文献

Flood risk management has become important more than ever, because an escalating threat of unpredictable and extreme weather is affecting flood-prone communities. People-centred risk communication has been proposed as an effective strategy that can stimulate people to protect themselves against flood risks. However, little research with a sound theoretical underpinning has been done to examine the effectiveness of such a strategy in developing countries. We use a field experiment to analyse how risk communication can influence households’ intentions to implement mitigation measures. Our results show that communicating about the risk of floods and how to cope with floods significantly increased both threat and coping appraisals, and thereby motivated households to take more non-structural measures. While formal risk communication had certain direct effects on mitigation intention, informal risk communication percolated through psychological variables. Risk communication should focus on coping capacities for financial measures and address the problems of wishful thinking and disaster subculture of flood-prone households. Furthermore, women’s participation in risk communication did not change the intentions to take mitigation measures of the male household heads in the Vietnamese Mekong Delta.  相似文献

Megaregion has emerged as a new dimension of global urbanization. A megaregion approach based on polycentric strategy is deemed to enhance regional economic competitiveness. Numerous studies have highlighted the economic benefits, celebrated the spill-over effects, and outlined the creative potentials of contemporary megaregion policies in different nations worldwide. However, further policy instruments require the knowledge about the achievement and failure of megaregion policies that seek for spatial, economic, social, and environmental efficiency and sustainability. This paper introduces China’s megaregion policy and proposes an analytical framework for performance evaluation from four principle domains (rational urban growth, economic development, social equity, environmental protection) at three levels (internal collaboration, integral development, and overall development). Using a case of the Megaregion around Hangzhou Bay (MAHB), we find very limited success of China’s megaregion policy. In particular, the megaregion policy only accomplishes the economic goal, and fails to achieve the goals of rational urban growth, environmental protection, and social equity. A series of mechanism based regressions are established and show that the implementation duration of megaregion policy: (1) associates positively with the economic growth; (2) relates negatively to social equity and urban rational growth; and (3) has no significant relationship with improved environmental quality. Institutional fragmentation, no unified spatial planning, and inadequate legislation at megaregional level are the underlying causes of the expected performances within the policy context of governance itself. We finally propose some possible solutions and discuss the implications for spatial polycentric governance. The demonstrated methodological framework can be applicable to other megaregions around the world. This paper is thus believed to provide some new insights for land use policy.  相似文献

Many low-income countries are integrated into apparel global value chains through foreign direct investment (FDI), including Lesotho, which has become the largest Sub-Saharan African apparel exporter to the US under the African Growth and Opportunity Act. More recently, South Africa has emerged as a new apparel export market in Lesotho. The two markets are supplied by different types of FDI firms – affiliates of Taiwanese transnational producers and South African manufacturers – which are part of different value chain variants. The paper assesses the implications for industrial upgrading and development of integration into these two value chain variants in Lesotho, drawing on firm-level and institutional interviews. We show that their different characteristics in terms of investors’ motivation, governance structure, end markets, firm set up and most importantly and causally, ownership and embeddedness have crucial impacts on functional, product and process upgrading, local linkages, and skill development.  相似文献

Although ‘Seguro Popular’ (SP), a healthcare programme for the uninsured, has been in place in Mexico for more than a decade, its consequences for international migration both to and from the country have received little scholarly attention. Using the spatial variation in the programme’s coverage generated through the rollout over time, this paper examines the effects of SP on the number of emigrants and return migrants per household. Based on data from Mexico’s National Survey on Demographic Dynamics for 1997–2014, the analysis confirms that being affiliated to SP does not reduce the number of emigrants per household, but such affiliation is, however, positively related to the number of returnees per household. These results are valid across different subsamples of the population and time periods and are robust to omitted variable bias. Our findings have important implications for understanding the effects of social protection policies on international migration patterns.  相似文献

The dilemma between preserving farmland and urbanization has attracted many policymakers’ attention. One sound solution that has been practiced in several developed countries is the “transfer of development rights” (TDR). This study examines a specific TDR program in China—the Chongqing Land Quotas Trading program. We use a synthetic control method on the 2001–2014 statistics of 57 prefectures to quantitatively assess the program’s effect on farmland preservation and economic growth. A mixed method, including both satellite image analysis and qualitative interviews, was also used to obtain some intuitive evidence to understand the mechanism of this program. We find that the Chongqing TDR program has substantially reduced the loss of farmland and played a significant role in stimulating economic growth. We argue that the use of TDR might effectively address the farmland preservation and urbanization dilemma in China.  相似文献

The West Coast region of New Zealand has experienced significant structural economic changes since the 1980s. These changes have been a result of state imposed land use restrictions that limited productivist activities such as logging and mining, which in turn have been overlain by the effects of changes in national and global resource demand. This has led to both job loss and local resentment to what is seen to be external political and environmental interference in the region. Such changes overlay on-going boom-and-bust cycles experienced in the region’s resource dependent communities and the state’s pursuit of neo-liberalism from the 1980s, leading to the loss of state support and employment in the region. Regional path-dependence and ‘lock-in’ centred on productivist activities and the slow realisation of the need to diversify the economy have not helped. The region has under-performed in comparison with national trends economically and demographically reflecting and reinforcing local path dependence. The gradual growth of the service and tourism economies marks a new use for land resources and slow structural economic change. However, in the absence of governance processes that allow for collaborative planning to resolve conflicts over future trajectories for the region, conflicts over land uses, resources and access are likely to persist.  相似文献

Abstract

Does decentralisation promote clientelism? If yes, through which mechanisms? We answer these questions through an analysis of India’s (and the world’s) largest workfare programme, the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), in two Indian states: Rajasthan and Andhra Pradesh (AP). The two states adopted radically different implementation models: Rajasthan’s decentralised one stands in contrast with Andhra Pradesh’s centralised and bureaucracy-led model. Using a mixed method approach, we find that in both states local implementers have incentives to distribute MGNREGA work in a clientelistic fashion. However, in Rajasthan, these incentives are stronger, because of the decentralised implementation model. Accordingly, our quantitative evidence shows that clientelism is more serious a problem in Rajasthan than in AP.  相似文献

There have been studies on how pastoralists assess and choose the resources required for their livestock, but little research analysing whether livestock are matched to the available resources in a seasonal migratory system by an entire pastoral community over a year. This paper reports a case study of pastoralists in Kazakhstan which shows how the inter-relation of biophysical, institutional and economic factors results in the imperfect matching of livestock numbers to the distribution of forage resources. The research is based on a three-year study using anthropological interviews, formal survey data, and remotely sensed data covering all livestock (25,000 smallstock and approximately 2300 cattle, horses and camels) in a study area of 60,000 km2 for an entire annual cycle; a combination of methodologies and geographical coverage that provides a comprehensive estimation of the factors that influence the pastoral exploitation of this human-managed, complex ecosystem. The research finds that the pastoralists are subject to a number of limitations in using biophysical niches which might otherwise provide the best feed and water resources for their animals at a particular season and site. Different ecozones offer seasonally-shifting advantages and disadvantages for the livestock, but livestock owners are also economically differentiated. The interplay between economic and biophysical factors exemplifies the multi-faceted character of pastoralists’ decision-making about site selection within a relatively open rangeland tenure system. Only those with the largest livestock holdings distribute their livestock to take advantage of the best seasonal resources. Despite the wide availability of biophysically suitable sites, most livestock owners’ choices are compromised and therefore frequently suboptimal, prompting the conclusion that natural resource matching is constrained.  相似文献

The forest transition is a concept used to describe and explain the transition from a dwindling to an expanding forest area in a given region or country. Three main explanations of the forest transition have been developed. The first is the “economic development path to the forest transition”, which contends that economic development and new agricultural technologies trigger rural-urban migration and agricultural intensification, leading in turn to the abandonment of marginal farmland and eventually to a forest recovery. The second is the “forest scarcity path to the forest transition”, which argues that the scarcity of forests is a major factor that encourages commercial tree plantations, reforestations and the conservation of woodlands. A third explanation has been advanced in certain developing countries. This explanation, referred to in this paper as the “diversification of rural livelihoods path to the forest transition”, holds that rural households must adjust to outside forces, including globalization and neoliberal economic policies, and that those adjustments marginalize smallholder farming, allowing for the expansion of forests. This paper describes and explains the onset of a forest transition in the Mixteca Alta UNESCO Global Geopark, in the state of Oaxaca, Mexico. Based on qualitative fieldwork and the analysis of official statistics and land-use/cover maps, we contend that the three paths to the forest transition overlap in our study area. This implies a fuller and more complex explanation of the forest transition, which is crucial to understand the expansion of woodlands in other regions of Mexico and the developing world.  相似文献

A rich body of literature exists for explaining the role women play in ensuring their household’s food security; however, as far as their own food security is concerned, little attention has been given. Therefore, this research collects evidence on the relationship between women’s empowerment and their own food security (access) in the rural areas of Azad Jammu & Kashmir (AJK). Data were collected from the households of 600 rural women. The results provide insights that the domains of legal rights, information and communication technologies (ICTs), social support and familial rights, can be a significant pathway for enhancing the food security of women as more bargaining power of women over the utilization of resources could result in a good quality of food choices and more expense on food items due to these rights. Besides, understanding food insecurity also requires considering gender norms as in this study, the infrastructural facilities and sense of land entitlement provide unexpected non-significant results. Though women help in the mounting necessities of their families, they are unable to enhance the food requirements for themselves due to restricted mobility and less economic opportunities. This is mainly due to the poor infrastructure, and more importantly, the lack of access to resources, especially land, because of lack of knowledge and self-confidence. Notably, the fear of conflict and domestic violence may also impede women from fighting for their rights, which results in poor access to food. Hence, by understanding the household makeup from women’s perspectives and customs, the findings from this study can help and guide policymakers in developing more appropriate strategies to improve the food security of women.  相似文献

This study explores local people’s attitudes towards urban planning, and the effects of development benefits on local support for planning in Kumasi, Ghana. Kumasi is a rapidly urbanising city in Ghana where urban growth between 2000 and 2010 exceeded 5%, and where local support for urban planning has not been studied adequately. Based on Kumasi Metropolitan Assembly, Town and Country Planning Department and Ghana Statistical Service’s residential area classifications, household survey with 360 respondents were conducted in nine high, middle and low class neighbourhoods in Kumasi, in addition to interviews with six representatives from two planning agencies. Results indicated that two-thirds of the household respondents were positive towards urban planning and support urban planning. The household respondents were aware that more development benefits are possible from an inclusive and pro-poor urban planning. There appears to be correlation between development benefits obtained by local people from urban planning, and support for urban planning, indicating that development benefits impact people’s attitudes towards urban planning. Some of the main problems are social and spatial inequity among people living in different classes of residential neighbourhoods, and lack of locals’ inclusion in urban planning and management. There is a need to clearly address these issues, so that urban planning may get the support of local people which may lead to sustainable urban development.  相似文献

Pakistan is highly vulnerable to extreme climatic events, such as floods and droughts. This study determines the farmers’ risk perception, risk attitude, adaptation measures and various aspects of vulnerability to climate change (e.g. floods, droughts, heavy rainfalls, pests and disease) at farm level in rural Pakistan. The risk perception and attitude of farm households are crucial factors that influence farm productivity, investment and management decisions at this level. A well-designed questionnaire was used to interview 720 farm households from six districts of the Khyber Pakhtunkhwa province. A binary logit model was used to determine the main factors that affect the choice of adaptation strategies of the farm household. The findings revealed that crop diversification, changing crop varieties, altering the crop calendar, varying the fertilizer used, mulching and farm insurance were the main adaptation strategies followed by farm households. The results of the binary logit model revealed that age, education, farm size, household size, credit accessibility, annual income and the perception on the increase in temperature and decrease in rainfall had significant influence on the selection of the adaption strategies. The findings of this study can provide guidance, policy recommendations and reference for future researchers.  相似文献

Economic reform in China has resulted in rapid urbanisation over the past three decades, changing the urban and rural landscape dramatically. A large amount of farmland was developed, leading to conflict between construction demand and farmland protection. In response, the “Link Policy” was proposed in 2005 that seeks to concurrently preserve farmland while providing for urban expansion through land exchange. The effectiveness of the Link Policy has not been systematically investigated. The purpose of this study is to analyse and evaluate outcomes of the Link Policy objectives from both a participant and investigator’s interpretive perspective. Ezhou, the first experimental city to implement the Link Policy in Hubei Province in central China, was selected as a case study area. Eight different communities in Ezhou were visited and 160 semi-structured interviews were conducted with resettled rural residents in March 2016. A combination of interviews and investigator field observations were used to evaluate the Link Policy objectives. The results show that participants recognize and support improving rural living conditions and coordinating urban-rural development, but the Link Policy failed to achieve the objectives of preserving farmland, protecting farmers’ land use rights and interests, and facilitating agricultural production. Participants perceived concentrated resettlement communities to be more efficient in land use compared to more expansive rural settlements, but vacant apartments for commercial use in resettlement areas account for a large proportion of land suggesting inefficiency in the land exchanges. We suggest policy changes to achieve more successful implementation of the Link Policy.  相似文献

The distinct urbanization process of China has attracted worldwide attention because of its impressive speed, massive scale, and policy intervention. However, the interrelationship between urban expansion and government policies is still not well understood. The Pearl River Delta Urban Agglomeration of China is the first national pioneering urbanization area since the implementation of the policy “Reform and Opening-up” in the late 1970s. Here we compared the spatial and temporal patterns of urbanization in two leading cities of the Pearl River Delta (i.e., Guangzhou and Shenzhen, the provincial capital and the first Special Economic Zone of China, respectively) from 1975 to 2015, using Landsat data integrated with urban growth and landscape metrics analysis, and examined possible footprints of major economic and urbanization policies. Our results illustrated that urban land areas in both Guangzhou and Shenzhen have experienced magnificent annual growth rates at 8.1% and 11%, respectively between 1975 and 2015. On average, Shenzhen witnessed substantially higher urban growth rate than Guangzhou during the past four decades, particularly in the initial period (1978–1990) when the Reform and Opening-up policy was launched and Shenzhen was designated as the first Special Economic Zone in China in the late 1970s. However, the speed of urban expansion in Shenzhen became considerably lower than Guangzhou from 2005 to 2015, subject to physical conditions and a series of urban land use policies. Both cities showed a generally similar dynamics of urban growth forms with leapfrogging as the predominant type of urban growth at first and then edge-expansion while the contribution of infilling in Shenzhen was higher than that in Guangzhou, especially since 2005. The urbanization processes characterized by landscape and urban growth metrics revealed that a diffusion-coalescence-diffusion-coalescence process was identified for Guangzhou, while Shenzhen was generally consistent with the diffusion-coalescence urban growth hypothesis.  相似文献
