Regulating services in poverty-ecosystems dynamics： evidences from South Asia

Valuation of ecosystem services has been sought as effective tools that enable the decision makers in designing the cost effective response policies for management of ecosystems towards alleviating the poverty especially in economically poor regions like South Asia. Various directions and linkages between poverty and degradation of ecosystem and reduced flow of ecosystem services can better be understood if the regulating services like hydrological flow and carbon sequestration by forest, and nutrient cycling and bioremediation： by wetlandv can be captured in monetary unit. South Asian Countries including India. Nepal, Pakistan and Bangladesh are the hotspots of poverty where poor depend upon various ecosystem services for their livelihoods and allocation of resource for conservation of ecosystems would have additional merit if regulating services are captured and internalized into the pubtic policy.The paperfirst raises problematic issues in valuation of regulatig ecosystem services, and attempts to link it withthe dependence of poor. Second, complexities of poverty-ecosystem dynamics are discussed. Thirdly, the possible in-tervention to achieve poverty alleviation goal is analyzed with the help of some examples from accounting and valua-tion of regulating services of lndian forest. Finally, the paper suggests that greater attention is needed to do credibleand better valuation of regulating Services so that insight from these ean be used in understanding the impact of degradation of ecosysterns On poor people.     

Poverty and the management of natural resources: A model of shifting cultivation

It is frequently asserted in the environment/development literature that severe poverty causes the neglect of worthwhile investments, resulting in deforestation and other resource degradation. While microeconomic theory does suggest a relationship between poverty and the evaluation of investments, the environmental impact is not so simple. This paper develops a dynamic theory of “shifting cultivation,” with special attention to an environmental impact variable: the length of time a given field is cultivated before a shift to the next. The model indicates that poverty reduction will lead in some ways to accelerated extraction of a natural resource, but also to a longer extraction period. The results therefore provide support for claims of an indirect environmental benefit from the primary goal of alleviating rural poverty. The impact of discount rates, prices, and other parameters are also explored.     

非传统生态脆弱区贫困群体的生态资源感知及生态脱贫意向分析——以山东地区的政府生态扶贫调查为例

依托山东地区政府生态扶贫实地调查所获得的776份问卷数据,运用二元Logistic模型对非传统生态脆弱区贫困群体的生态资源感知及生态脱贫意向进行实证分析。样本区域贫困群体的生态资源感知指数介于2.307~2.953之间,无较大差异,超过90%的贫困群体存在积极生态脱贫意向。实证结果表明:(1)非传统生态脆弱区生态资源韧性大,贫困群体的生态资源供给感知敏感度低于生态资源需求感知;(2)非传统生态脆弱区贫困群体的生态脱贫意向首先直接受到生态保护补偿扶贫政策的刺激,除了补助金补偿,还应通过就业机会补偿、市场化补偿等多种形式刺激贫困群体的发展积极性;(3)其次生态脱贫意向还受到生态资源感知、生态脱贫政策和社会人口特征的交互影响。     

Persistent and Consistent Poverty in the 1994 and 1995 Waves of the European Community Household Panel Survey

This paper focuses on the mismatch between income and deprivation measures of poverty. Using the first two waves of the European Community Household Panel Survey, a measure of relative deprivation is constructed and the overlap between the relative income poor and relatively deprived is examined. There is very limited overlap with the lowest relative income threshold. The overlap increases as the income threshold is raised, but it remains true that less than half those below the 60 percent relative income line are among the most deprived. Relative deprivation is shown to be related to the persistence of income poverty, but also to a range of other resource and need factors. Income and deprivation measures each contain information that can profitably be employed to enhance our understanding of poverty and a range of other social phenomena. This is illustrated by the manner in which both income poverty and relative deprivation are associated with self-reported difficulty making ends meet.     

The (evolving) role of agriculture in poverty reduction—An empirical perspective

The role of agriculture in development remains much debated. This paper takes an empirical perspective and focuses on poverty, as opposed to growth alone. The contribution of a sector to poverty reduction is shown to depend on its own growth performance, its indirect impact on growth in other sectors, the extent to which poor people participate in the sector, and the size of the sector in the overall economy. Bringing together these different effects using cross-country econometric evidence indicates that agriculture is significantly more effective in reducing poverty among the poorest of the poor (as reflected in the $1-day squared poverty gap). It is also up to 3.2 times better at reducing $1-day headcount poverty in low-income and resource rich countries (including those in Sub-Saharan Africa), at least when societies are not fundamentally unequal. However, when it comes to the better off poor (reflected in the $2-day measure), non-agriculture has the edge. These results are driven by the much larger participation of poorer households in growth from agriculture and the lower poverty reducing effect of non-agriculture in the presence of extractive industries.     

On Impatience, Economic Growth and the Environmental Kuznets Curve: A Dynamic Analysis of Resource Management

The paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation.Using a recursive specification of time preferences, we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation. We examine the relationships between economic growth and environmental quality. Endogenous discounting provides new insights in the economic dynamics underlying the environmental Kuznets curve. By treating growth as endogenous, we examine how externalities and economic growth interact with each other. We investigate how economic development can contribute to an increased demand for environmental preservation. As an important new result, we also show how poverty can contribute to environmental degradation.     

贫困按要素分解:方法与例证

本文构建了两个贫困分解框架,一个用于分解贫困的水平,另一个用于分解贫困的变化,这两个方法的独特之处是建立了贫困与生产要素(即资源禀赋)总量及其分配之间的数量关系。具体地说,一个给定的贫困发生率可以被分解为要素或资源短缺的贡献,外加要素分配不均等的贡献。贫困发生率的变化则可分解为由要素的水平变化引起的,或由要素的不均等分配变化引起的。将这两种分解方法用于中国农村的数据,我们发现要素的不均等分配而非资源短缺是导致贫困和贫困变化的主要原因。     

Microcredit,Labor, and Poverty Impacts in Urban Mexico

Improved household accessibility to credit is a significant determinant of intra‐household allocation of labor resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads to new hires outside the household. This paper contributes to the existing literature on microcredit in two important ways. First, it investigates the routes through which microcredit reaches those in poverty outside the household. We test whether by lending to the vulnerable non‐poor microcredit can indirectly benefit poor laborers through increased employment. Second, we conduct the study in the context of urban poverty Mexico. This is relevant when considering that labor often represents the only source of livelihoods to the extreme urban poor. Our findings point to significant trickle‐down effects of microcredit that benefit poor laborers; however, these effects are only observed after loan‐supported enterprising households achieve earnings well above the poverty line.     

The economics of poverty in poor countries

This paper examines the links that have recently been studied between poverty, high fertility and undernourishment, on the one hand, and degradation of the local environmental-resource base and civic disconnection, on the other, in poor countries. An account is offered of a number of pathways involving positive feedbacks that create poverty traps, in which certain identifiable groups of people in an economy can get caught even when the economy in the aggregate experiences economic growth. The relevant policy implications are noted.     

Natural resource accounting for Indian states — Illustrating the case of forest resources

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth.     

Poverty and resource dependence in rural India

Previous studies of rural households in developing countries have tended to find that the dependence of these households on common-pool resources declines with income. Our study of households in Jhabua, India, finds a more complex relationship. Using the share of resource income in total long-run or “permanent” income as our dependence measure—which we argue is more appropriate than the short-run income-based measure commonly used in the literature—we find that for households that collect any resources at all, dependence exhibits a U-shaped relationship with income. That is, the poorest and richest households depend more on resources than households with intermediate incomes. The poorest and richest households are also found to be least likely to collect, however, indicating that resource use at the income extremes is bimodal—either zero or above average. Moreover, the observed trends for resources as a whole are not mirrored in those for individual resources. Dependence on fuelwood and dung declines with income, for example, while dependence on fodder and construction wood increases. These findings suggest that common-pool resources are a productive source of income not just for the poor but also for the rich, and that improvements in the stocks of these resources can potentially form the basis of poverty reduction efforts in these economies.     

论退耕还林与减缓山区贫困的关系

现有扶贫开发模式以改善贫困地区生产条件和开发资源为导向,但是对生态较为脆弱的大多数贫困山区来讲,若不考虑社区生态系统的保护,开发式扶贫有可能导致越扶越贫。本文在分析山区贫困的一般特征基础上,通过对有关环境与贫困相互关系的理论认识,结合正在推进的退耕还林工程实践,提出林业扶贫是减缓山区贫困的有效途径,指出应从落实山区林权制度、建立生态移民制度、改善农业补贴制度以及强化山区扶贫管理体制等方面创新山区扶贫开发模式。     

The role of domestic timber markets in tropical deforestation and forest degradation in Ecuador: Implications for conservation planning and policy

Studies about the impact of the timber trade on tropical forests have often oversimplified process complexity and underestimated regional variability. This study shows that forest degradation and clearing in Northwest Ecuador between 1983 and 1992 was closely linked to commercial logging. A key finding is that domestic demand is critical for shaping timber extraction and, hence, forest degradation and deforestation in this region. Low timber prices for roundwood and sawnwood at the origin, which are bolstering unsustainable forest extraction, have not been affected by market liberalization. This suggests that conservation initiatives that target international trade linkages may only be partially successful, even when they do what they are intended to do. Results suggest that market-based incentives are more likely to produce the desired results if they target and support timber producers directly. These findings are also relevant for other regions where domestic markets are a significant drive for deforestation and where local markets are supplied through the activities of small-scale, labor-intensive primary producers. Also, by emphasizing areas where logging is a dominant force, meso-level studies, like this one, not only help to more accurately estimate the impact on local forests, but also identify major resource flows and the factors promoting or hindering sustainable use, and those affecting the effectiveness of policy options.     

Forest incomes and rural livelihoods in Chiradzulu District, Malawi

This paper examines forest income among rural dwellers in one of Malawi's most densely populated districts, Chiradzulu. 160 households were interviewed in two sites, only 20 km apart, purposely selected on the basis of access to a forest reserve. People are extremely poor, with 97% having incomes of less than 1 USD/day. Forest income constitutes around 15% of total income; only non-farm income (47%) and agriculture (28%) rank higher. The poorest segment depends more on forest income than the least poor group, but the medium income group exhibits the highest dependence. Fuelwood constitutes the major source of such income followed by fodder. The incomes mainly support current consumption. People with better access to the forest reserve have higher total income, forest income, and relative forest income. As revealed through a Gini-coefficient analysis, forest resources have an important income equalizing effect across rural households. A particular group of resource poor farmers (8.1% of sample), with little access to agricultural land and a high representation of female heads, derives an average of 65% of their income from the forest. An important policy lesson is that restricting people's access to forest resources can have substantial effects on household livelihoods and welfare, and would serve to increase income inequalities in the area. Livelihood researchers should now recognize the substantial income from forest resources.     

Community–Industry Contracting over Natural Resource use in a Context of Weak Property Rights: The Case of Indonesia

Decentralization in Indonesia has resulted in an increased influence of local communities over the terms of logging agreements with timber companies. The outcomes of such community–company negotiations vary significantly across communities. What are the conditions that cause this variation, and how can the outcomes be more effectively and efficiently influenced by third-party actors such as the local government or NGOs? This paper addresses these questions by developing a game-theoretic model to illustrate the strategic interactions between communities and companies. The model allows for endogeneity of de facto property rights and bargaining positions. We show that third-party actions to improve the community’s bargaining position by raising its reservation utility may result in an increase in the area logged and thereby harm the environment. Our results indicate that the strategy of intervention matters. In particular, strategies that raise the sensitivity of interventions to local logging threats are likely to be more cost-effective in supporting communities and reducing forest degradation than more indiscriminatory strategies. The model will be relevant to other situations where communities negotiate contracts over natural resource use with outside actors in a context of weak property rights, a situation increasingly observed in other developing countries.     

Escaping Poverty: Risk-Taking and Endogenous Inequality in a Model of Equilibrium Growth

Recent macroeconomic models of income distribution generate equilibria characterized as poverty traps. These models specify a production indivisibility such that, due to problems of asymmetric information in credit or capital markets, poor agents are never able to acquire the resources necessary to overcome the indivisibility. In the context of an equilibrium growth model, this paper demonstrates that faced with such constraints, poor, risk-averse agents have incentives to voluntarily take on risk in the hopes of exiting poverty. Each period they remain in poverty, they sacrifice a small amount of current consumption to pool resources for this risky activity. Risk-taking, economic mobility, and the distribution of income are generated endogenously. Furthermore, beginning from identical endowments, “initial” inequality also emerges endogenously. It is shown that voluntary risk-taking eliminates many potential steady-state equilibria of this and other models—those that exhibit individual poverty traps. All agents (or dynasties) expect to escape at some future date, perhaps after an extended spell in poverty.

Frontiers and sustainable economic development

Exploiting new resource “frontiers,” such as agricultural land and mineral reserves, is a fundamental feature of economic development in poor economies. Yet frontier-based development is symptomatic of a pattern of economy-wide resource exploitation in developing economies that: (a) generates little additional economic rents, and (b) what rents are generated are not being reinvested in other sectors. Such development is inherently unsustainable. The following paper explains this phenomenon, and provides evidence that long-run expansion of agricultural land and oil and natural gas proved reserves across poor economies is associated with lower levels of real income per capita. The paper proposes a frontier expansion hypothesis to explain why the structural economic dependence of these economies on frontier land expansion and resource exploitation is not conducive to sustained long-run growth. The key to sustainable economic development in poor economies will be improving the economic integration between frontier and other sectors of the economy, targeting policies to improved resource management in frontier areas and overcoming problems of corruption and rent-seeking in resource sectors.      

The effect of transfers on household expenditure patterns and poverty in South Africa

This paper uses household level unit record data from South Africa to examine the behavioural and welfare impacts of private and public transfers. We allow for joint endogeneity of resource variables and the expenditure shares. Our results show that crowding out of private transfers as a result of the introduction of public pensions holds only for poor households and not for the non-poor. Both private transfers and public pensions significantly reduce poverty but private transfers have a larger impact on expenditure patterns. The results also reject the hypothesis of income pooling underlying the conventional unitary model by finding that the marginal impact on expenditures are different for public pension received, private transfer received and other resources flowing into the household. The principal conclusions are robust to changes in specification.
