耕地转出对农民家庭贫困脆弱性的影响及其区域差异分析

关注耕地转出行为对农户贫困脆弱性的影响,对于农民家庭的持久脱贫及农村反贫困政策的制定意义重大。基于CFPS两期全国整合样本的面板数据,在对农户贫困脆弱性进行测算的基础上,运用倍差法、OLS模型及倾向得分匹配倍差法,实证检验耕地转出对农民家庭贫困脆弱性的影响及其区域差异。结果表明：（1）耕地转出行为的发生降低了农户的贫困脆弱性,是一种有效的扶贫手段,在帮助部分农户抵御收入风险上起到了积极作用;（2）耕地转出规模的扩大并未显著改善农户的贫困脆弱性状况;（3）控制变量也对农户贫困脆弱性产生了不同程度的影响,其中户主性别、户主年龄和家庭住房净资产显著正向影响农户的贫困脆弱性水平,而户主受教育程度、家庭劳动力数、健康状况、现金和存款数及当地经济发展水平等变量显著负向影响农户的贫困脆弱性水平;（4）耕地转出行为对农民家庭贫困脆弱性的影响呈现出一定的区域差异性,对东、中和东北地区农户贫困脆弱性的降低起到了显著促进作用,但对西部地区农户的减贫作用并不明显。     

Networks and spatial segregation in the production of urban poverty in São Paulo

This article discusses the importance of social networks as survival strategies, testing the impact of segregation on the structure and organisation of personal networks of low-income individuals. It presents preliminary results of an ongoing study on personal networks of individuals living in situations of poverty in São Paulo. We analyse the characteristics of 89 personal networks of poor individuals living in three urban locations, characterised by different social contents and different contexts of segregation. The results indicate a considerable heterogeneity of networks (in terms of size, diversity of sociability spheres, among other dimensions) and a strong localism, which is commonly found in the three different urban contexts. At the same time, the analysis suggests a low impact of segregation and a more complex relationship between networks and space than previously described by the international literature.     

Whose marginalisation? Politics around environmental injustices in India's Chilika lagoon

The article examines marginalisation in small-scale fishing communities in a large lagoon system. It explores what marginalisation looks like from the fishers' point of view, and examines the extreme discrepancy between the official government account of the lagoon's resources, and the fishers' account. We analyse two major drivers of marginalisation: (1) role of aquaculture development in the loss of resource access rights and decline of local institutions, and (2) ecological displacement and livelihood loss brought about by the opening of a new (2001) “sea mouth”. We consider evidence collected through household- and village-level surveys combined with a host of qualitative and quantitative research methods. The fishers' point of view, and the data obtained using this point of view as a guide, presents a more complex, multidimensional concept of marginalisation, not simply as a state of being but as a process over time, impacting social and economic conditions, political standing, and environmental health.

The Deforestation of Rural Areas in the Lower Congo Province

The Lower Congo is one of eleven provinces in the Democratic Republic of Congo, and is located southwest of Kinshasa Town Province. It has an area of approximately 53.947 km² with a population of 1 504 361 at an estimated 237 persons per km². The Province comprises five districts, including Lukaya and Cataracts where rural poverty is severe and the population struggle to make a living through agriculture and woodcutting. These activities result in excessive resource exploitation. The high demand for foodstuffs and the high consumption of wood (for energy, construction and export) in Kinshasa, the capital city of the Democratic Republic of Congo and the expanding towns of Matadi and Boma in the Lower Congo Province, are speeding the deforestation rate and unbalancing forest ecosystems. In addition there is the stress resulting from reduced josher (the rest period for agriculture ground), plus climate change and erosion. The phenomena that that we need to address in these two districts include deforestation, reduced josher, excessive agriculture, erosion, burning and climate change which taken together largely explain the current soil degradation. These areas are marked by excessive post deforestation savannah formation and extended areas of sandy soil, distributed throughout grass and shrub savannahs. This desertification, which is rampant in Lukaya and Cataracts, risks imprisoning the rural population in a vicious cycle of poverty if adequate solutions are not found.     

The livestock revolution, food safety, and small-scale farmers: why they matter to us all

Global consumption, production, and trade of livestock products have increased rapidly in the last two decades and are expected to continue. At the same time, safety concerns regarding human and animal disease associated with livestock products are increasing. Efforts to increase public health safety standards aimed at legitimately reducing the risks of human and animal disease have focused internationally on standards to regulate the movement of livestock products. There is concern, though, that measures to regulate these standards internationally, such as the WTO SPS measures that in part aim to open international markets, may marginalize small-scale poor producers. The cycle of poverty they are trying to escape through livestock production may, in fact, widen, leading to increased global poverty, malnutrition, and disease. Developing and developed nations alike should be concerned with public and private efforts to address appropriate food safety policies to reduce the likelihood of this effect. Analysis of the impact on small-scale livestock farmers is needed, as well as solutions that consider joint public and private sector initiatives. Costly farm to table tracking systems are not an option, but locally orchestrated vertically integrated systems may have merit in reducing food safety risks and in providing small-scale farmers with increased access to markets, locally and internationally. Increased scientific and technical capacity, and training of WTO officials from developing nations is also needed.

THE FOREST–HYDROLOGY–POVERTY NEXUS IN CENTRAL AMERICA: AN HEURISTIC ANALYSIS

A ‘forest–hydrology–poverty nexus’ hypothesis asserts that deforestation in poor upland areas simultaneously threatens biodiversity and increases the incidence of flooding, sedimentation and other damaging hydrological processes. This paper uses rough heuristics to assess the applicability of this hypothesis to two montane forested countries in Central America: Guatemala and Honduras. We do so by using simple rules of thumb to identify watersheds at greater risk of hydrologically significant land use change, using information about land cover, slope, and watershed size. The location of these watersheds is compared to spatial maps of poverty and forests. We find plausible evidence for a forest–biodiversity–poverty connection in Guatemala, and to a lesser extent in Honduras.     

The interaction between seaweed farming as an alternative occupation and fisher numbers in the central Philippines

Alternative occupations are frequently promoted as a means to reduce the number of people exploiting declining fisheries. However, there is little evidence that alternative occupations reduce fisher numbers. Seaweed farming is frequently promoted as a lucrative alternative occupation for artisanal fishers in Southeast Asia. We examined how the introduction of seaweed farming has affected village-level changes in the number of fishers on Danajon Bank, central Philippines, where unsustainable fishing has led to declining fishery yields. To determine how fisher numbers had changed since seaweed farming started, we interviewed the heads of household from 300 households in 10 villages to examine their perceptions of how fisher numbers had changed in their village and the reasons they associated with these changes. We then asked key informants (people with detailed knowledge of village members) to estimate fisher numbers in these villages before seaweed farming began and at the time of the survey. We compared the results of how fisher numbers had changed in each village with the wealth, education, seaweed farm sizes, and other attributes of households in these villages, which we collected through interviews, and with village-level factors such as distance to markets. We also asked people why they either continued to engage in or ceased fishing. In four villages, respondents thought seaweed farming and low fish catches had reduced fisher numbers, at least temporarily. In one of these villages, there was a recent return to fishing due to declines in the price of seaweed and increased theft of seaweed. In another four villages, fisher numbers increased as human population increased, despite the widespread uptake of seaweed farming. Seaweed farming failed for technical reasons in two other villages. Our results suggest seaweed farming has reduced fisher numbers in some villages, a result that may be correlated with socioeconomic status, but the heterogeneity of outcomes is consistent with suggestions that alternative occupations are not a substitute for more direct forms of resource management.
