Coastal areas are worldwide characterized by multiple pressures generated by high levels of urbanization and by conflictual and inappropriate uses. The establishment of protected areas represents a tool to contrast such pressures. The integration between planning tools represents a key issue, in particular in the Mediterranean area; hence, it has been addressed by both legally binding acts and voluntary agreements and charters concerning coastal zone management as well as marine spatial planning. By looking at two Italian case studies and analyzing their planning documents currently in force, our study aims at assessing the level of integration in relation to planning and management of areas characterized by the coexistence of various nature protection regimes. Our analysis shows that, although integration seems to be a key point in the planning agenda and in spite of some improvements, an integrated management approach in Mediterranean coastal and marine areas is still in its infancy. The results of the analysis show that, rather than contributing to building an integrated approach to marine and coastal zone management, each planning tool focuses on complying with its sectoral, normative framework. This situation can partly be attributed to the multilayered, and complex, Italian framework, characterized by several categories of protected areas with their own legal act and objectives.  相似文献

Protected areas are cornerstones for biodiversity conservation, yet they can be controversial because of their potential impact on the livelihoods of local people due to restrictions on agricultural land use and the extractive use of natural resources. This study evaluates the impact of PAs on households’ livelihoods, as measured by total household income (THI) and livestock income (LI). We use a survey and a quasi-experimental design to gather socioeconomic and biophysical data from households living within, adjacent to and outside three national parks (NPs) in Ethiopia and employ matching methods to isolate the impact of NPs. Our findings suggest that there is no evidence that the establishment of NPs adversely affects local livelihoods. Instead, we find that households within and in adjacent areas to NPs have higher incomes compared to those living outside. Understanding the heterogeneity of the effect of NPs on local livelihoods can help in designing well-targeted policy interventions that improve conservation goals while also addressing livelihood concerns of resource-dependent local communities.  相似文献

This paper investigates Japanese consumers' willingness to pay for Marine Stewardship Council (MSC) ecolabelled seafood using a sealed bid, second price auction. Participants in an experiment in Tokyo were provided varying degrees of information about the status of world and Japanese fisheries and the MSC program in sequential rounds of bidding on ecolabelled and nonlabelled salmon products. A random‐effects tobit regression shows that there is a statistically significant premium of about 20 per cent for MSC‐ecolabelled salmon over nonlabelled salmon when consumers are provided information on both the status of global fish stocks and the purpose of the MSC program. This premium arises from a combination of an increased willingness to pay for labelled products and a decreased willingness to pay for unlabelled products. However, in the absence of experimenter‐provided information, or when provided information about the purpose of the MSC program alone without concurrent information about the need for the MSC program, there is no statistically significant premium.  相似文献

Most studies of the welfare impact of higher food prices adopt Deaton's approach, based on the first‐order effect of prices changes using income and expenditure survey data. This paper explores the impact of higher maize and food prices in Ghana and considers the sensitivity of results to changes in several assumptions. If second‐order effects are included, incorporating household response to price changes, the welfare impact of food price increases is more positive, but only modestly so. However, if we assume that marketing margins are constant in real terms rather than proportional to prices, the welfare impact is substantially more positive. These findings highlight the need for more research on the behavior of marketing margins under volatile prices.  相似文献

There is a rising concern that the ongoing wave of off-farm employment will have profound effects on agriculture-based environment problems-measured by the intensity of chemical fertilizer (CF) usage. Yet, our understanding of the regional heterogeneities of this effect remains scant. This research gap is addressed by using panel data of selected cities in Sichuan and Henan provinces in China, which are representative mountainous and plain regions respectively, to empirically examine the impact of off-farm employment on CF use. Our findings indicated that there exists an inverted “U” shaped relationship between off-farm employment and CF use in the mountainous region, whereas CF use is positively correlated with off-farm employment in the plain area. The increased CF inputs, which resulted from the substitution effect and remittance effect, can compensate for the negative effect of labor loss, while land marginalization is the main reason for the decrease in CF consumption at the later stage of urbanization in the mountainous region. Meanwhile, the deagriculturalization of farmers’ employment patterns decreases the intensity of CF usage, which resulted from the scale effect produced by land transfer and large-scale management in the plain region. Besides, the evolution pattern of this effect may present a similar trend in these provinces, but the turning point of plain regions would appear later than that of mountainous areas due to the inherently unique physical conditions and socio-ecological contexts. Based on the empirical results of this paper, some policy recommendations are provided.  相似文献

The Brazilian Amazon harbours 70 % of the world’s tropical forests and is essential to the country’s economy because it maintains biodiversity, sustains the livelihoods of the indigenous people and local communities, and provides ecosystem services such as water production, soil stabilization, flood prevention, and climate regulation. In the last three decades, the Brazilian government has established a regional protected area (PA) network that currently covers approximately 48 % of the region. Despite their importance, some sectors of the Brazilian society have argued that the expansion of the PAs across the region hampers the local economic development, because they make less area available for non-forest economic activities such as large-scale agriculture, mining, and power generation. In this study, we analysed the relationship between local economic growth and PA coverage in 516 municipalities in the Brazilian Amazon from 2004 to 2014. We modelled the impact of the coverage of the three types of PAs (strictly-protected, multiple-use, and indigenous lands) on the (i) compound annual growth rate (CAGR) of the real gross domestic product per capita (GDP per capita), and (ii) real gross value added per capita (GVA per capita) of the agriculture, industry, services, and government sectors in each municipality. The models also considered the following control variables at the municipal level: area, age, per capita GPD in 2004 (or per capita GVAs in 2004), population growth rate between 2004 and 2014, education index, deforested area outside PA per capita, deforested area inside PA per capita, degraded area outside PA per capita, degraded area inside PA per capita, and presence of illegal mining within PA. We applied spatial Durbin error models (SDEM) to analyse the direct, indirect, and total impacts of the PAs on the local economic growth. We did not find a statistically significant relationship between the local economic growth and PA coverage in any of the three PA groups evaluated. Only the total impact of the GVA per capita of the industry was negatively correlated with the coverage of the strictly-protected PAs. Our findings do not support the arguments used by some interest groups of the Brazilian society that the social and environmental gains generated through the expansion of PAs across the region constrain the overall local economic growth.  相似文献

Taxes on fats and sugar-sweetened beverages are deployed in the developed world to encourage healthier diets. How effective might such fiscal instruments be in emerging economies? We evaluate the impacts of a subsidy for palm oil, introduced as part of the public distribution system in three Indian states. Using variants of the difference-in-differences approach, we find that palm oil consumption increased, particularly in rural areas, as a result of the subsidy, and traditional oils were displaced by cheaper palm oil. However, the intervention did not significantly alter overall edible oil consumption. These results are robust to different specifications, alternative estimation samples, and the exclusion of households who may have been potential beneficiaries of other interventions. Impacts were higher in Tamil Nadu than in other states, and were higher for vegetarian households in rural areas. There was only weak evidence of spillover income effects on other food groups. Given India's dual burden of malnutrition, our analysis suggests that fiscal policy interventions have the potential to effectively nudge consumer choices towards healthier edible oil consumption.  相似文献

Agricultural biotechnology (genetic modification) has encountered resistance from many consumers, resulting in disparate regulatory approaches across different jurisdictions. The recent advent of CRISPR-Cas9, or gene editing, offers the potential for significant improvements in plant breeding. However, little is known currently about consumer responses to the technology. A factor often omitted from previous economic analyses of consumer acceptance of new food technologies is underlying human values or worldviews. Drawing upon cultural cognition theory and using data from a survey of Canadian consumers, we examine the influence of cultural values on food choice behaviours. Respondents’ pre-existing cultural values are measured on two dimensions: hierarchy-egalitarianism and individualism-communitarianism. Choice behaviours are captured using a discrete choice experiment featuring a sliced apple product with two consumer-oriented attributes (non-browning and antioxidant-enhanced) and three novel food technologies (gene editing, genetic modification, edible coating). Using a random parameters logit model with error components we find pre-existing cultural values to be significant determinants of choice behaviours. Individuals pre-disposed towards a hierarchical worldview are more accepting of novel food technologies, as are individuals with a communitarian worldview. While the use of gene editing results in negative marginal utilities in a food choice situation, the effect is not as large as with genetic modification, suggesting there is scope to ameliorate potentially negative reactions to the technology with value-compatible messages.  相似文献

Evaluating agricultural programmes requires considering not only the programmes’ influence on input and output indicators, but also considering the relationship between these indicators as embodied in the production technology. This article examines the impact on production of an intervention in the Ecuadorian Sierra designed to improve returns to potato production through training and through linking smallholders to high‐value markets. Critical to identifying the impact of the programme is the careful construction of a counterfactual and meticulous data collection. To assess the impact of the programme on production, a weighted estimation, where weights are constructed through propensity score matching, is employed to estimate a production function within a damage abatement framework. The function incorporates a series of interaction terms to assess the impact of the programme on the production technology. The findings provide evidence that the programme enhances yields both through a general shift in technology as well as increased input use. The results suggest that the use of effective farming techniques that are learned through the programme induce this technological shift.  相似文献

We use data from smallholder coffee farms in Vietnam to measure the technical efficiency of coffee producers, and the degree to which potential restrictions on the shadow prices of chemical inputs might reduce overall efficiency among these farmers. Using input‐oriented data envelopment analysis (DEA) we find the use of pesticide and herbicide accounts for a relatively small proportion of overall technical efficiency in the sample. We place restrictions on input shadow prices and show that restricting their importance does not dramatically alter patterns or measures of short‐run efficiency.  相似文献

Improving agricultural productivity has received a greater attention in recent years amid concerns about rising food insecurity, population pressures, and climate change. Many believe that better access to institutional credit, spanning microcredit as well as commercial and agricultural banks, can help rural households smooth risks, and access inputs and other technology to modernize agriculture and improve farm/nonfarm linkages. We use recently augmented household panel data spanning over 20 years in Bangladesh to examine the effects of rural credit expansion (both microcredit and formal bank channels) on outcomes for agricultural households. We find that microcredit has benefited households with lower landownings, raising agricultural income from activities such as livestock rearing that require less land, as well as nonfarm income diversification for all households, but with the strongest effect for landless or near‐landless households. We do not find effects of microcredit on crop income, but do, however, find that reported supply‐side credit constraints significantly lower crop income. Borrowing by both men and women has contributed to nonfarm income growth for marginal farmers, but only men's borrowing has contributed to nonfarm income growth among higher landowning groups.  相似文献

This paper makes use of the income variability generated by the macroeconomic crisis of 2001/2002 to examine schooling outcomes in Argentina. The effect of this macroeconomic swing is examined with a focus on whether the income or substitution effect dominates in the decision-making of young people. It is demonstrated that the probability of being in school was 6.5–10 percentage points higher in May 2002 than in 2001 for 15–18-year-olds. This is probably the largest (positive) effect found in the developing country literature so far and is comparable to the effect of a 10% increase in household income. For 19–25-year-olds, the probability is between 2 and 6 percentage points higher. Results are robust to a wide range of controls and specification checks. Difference-in-difference panel estimation corroborates these findings and shows that the increase in schooling seems to be driven by a decrease in school exits during the crisis.  相似文献

Market-oriented allocation of land resources is one of the main economic reforms in China. However, the influence of land transfer marketization (LTM) on green total factor productivity (green TFP) and its mechanisms remain unknown. Based on panel data of 30 provincial administrative regions in China from 2004 to 2016, this study attempts to establish mechanism among LTM, industrial structure and green TFP, which is measured by the Slack Based Measure DEA (SBM-DEA) model containing undesirable output, and empirically estimates the impact of LTM, the rationalization and optimization of industrial structure and their interactions on green TFP further. The results show that: 1) LTM has a significant promoting effect on the improvement of green TFP in China, and the effect is also significant in the eastern, central and western regions as well, indicating that the application of land transfer policy to regulate regional economic development is widespread in China. 2) The rationalization of industrial structure has significantly promoted the development of green TFP in China, as well as at the regional levels, and the effect decreases from the western region to the central and eastern regions. The optimization of industrial structure also has a promoting effect on green TFP in China and all the regions, but the regional differences of the effect are contrary to that of the rationalization of industrial structure, with a decreasing trend from the eastern region to the central and western regions. 3) The interaction between LTM and the rationalization of industrial structure has significantly inhibited the improvement of green TFP in China, and the regional variations of the restraining effect are higher in the western region, followed by the central and eastern regions. The interaction between LTM and the optimization of industrial structure also has a negative effect on green TFP in China, and the regional variations of the effect showing the decreasing trend from the eastern region to the western and central regions. Therefore, China should continue to adhere to the market-oriented urban land transfer system reform, actively play the role of the government in the industrial upgrading and industrial transfer, and formulate a differentiated land transfer system and industrial development policies based on the economic development and industrial characteristics of various regions, so as to achieve the sustainable development of China’s economy and society.  相似文献

Using China Family Panel Studies (CFPS), this study investigates factors associated with the choice of farmland leasing strategies and the impact of leasing options on farm performance. Particular attention is given to off‐farm employment and farm subsidies. Additionally, the study applies a selectivity‐based approach to assess the relationship between farmland leasing choices and farm businesses’ performance. Off‐farm employment, older and educated operators, large farms and old‐age pension plans increase the likelihood of leasing out farmland. Part‐time off‐farm employment, grain subsidies and mechanised farms increase the likelihood of leasing in farmland. Finally, the selectivity correction terms in the value of crop production are significantly negative in the choices of farmland leasing, indicating the presence of sample selection effects. Accounting for selectivity is essential to ensure unbiased and consistent estimates.  相似文献

This article is devoted to common yet quite specific approaches to valuation practice tasks that are involved in determining the market value of real properties in areas of possible land use changes. An intrinsic element of market value in such areas is the hope value, for which an option pricing model is used quite frequently.The authors propose a specially adapted Samuelson-McKean model for this task, which allows market value indication to be determined not only with the built-in development option, but also the dynamics of its components value in the current highest and best use and hope value – depending on the location of the given property. The greatest advantage of the Samuelson-McKean model is that it can be treated as universal for analyzing the range of possible indications of market value seeing as how its main task is to find a compromise between the interests of the buyer and the seller, which is the goal of any fair transactions and decisions.  相似文献

This paper tests the ‘systems of innovation’ hypothesis for a selection of crops in Ghana and Burkina Faso that have shown significant growth in production over an approximately 20-year period. The question is whether such growth can only occur if supported by a system of innovation. Using two indicators (a common understanding on objectives and priorities, and a high level of interactivity), we find little evidence for the existence of anything that might be considered a high functioning system of innovation.  相似文献

Western Australia has experienced an investment surge in the minerals sector of the economy in recent years. Unlike previous surges, this one involves a large proportion of mineral-processing projects. In this study, the differential effects on the WA economy of 25 mining and 10 mineral-processing projects are analysed using an economy-wide model of WA. The results indicate that: (i) both the mining and mineral-processing projects will have substantial flow-on benefits to the WA economy as a whole; (ii) on an A$1-million-invested basis, mineral processing has larger flow-on effects on employment and generates more export revenue than does mining once the projects are operational.  相似文献

To protect farmers from health care costs and risks to livelihood, most countries have developed special health and social insurance programmes specifically for farmers. While numerous studies have examined the determinants of participation in these programmes, little is known about how they influence famers' land and labour allocations. Without government‐sponsored health and social insurance, farmers may seek off‐farm employment in order to obtain similar benefits. Conditioning eligibility for social insurance on minimum land holdings and on‐farm work days can lead to delayed retirement and other forms of job lock. We investigate these issues using a unique dataset of 703,287 farms in Taiwan. After controlling for non‐random participation in Taiwan's social insurance programme, we find that the programme increases (decreases) on (off) farm labour supply, and decreases the amount of set‐aside land. This suggests that payments from social insurance substitute for those issued through land set‐aside programmes to some extent, and that failing to account for this substitution increases the cost of achieving both programmes' objectives.  相似文献

This paper presents the results from a survey of New York dairy farms that links manure management practices and farmer willingness to participate in voluntary environmental programs, focusing on those operations that are not automatically designated as Concentrated Animal Feeding Operations. A wide divergence is found between actual and recommended manure management practices on individual dairy farms (high), the apparent ability of farms to divert financial resources to environmental practices (mixed), and the willingness to participate in voluntary programs at various annual costs per cow (low). These findings have policy implications for the USDA/USEPA National Strategy for Animal Feeding Operations.  相似文献

Different socio-economic and environmental drivers lead local communities in mountain regions to adapt land use practices and engage in protection policies. The political system also has to develop new approaches to adapt to those drivers. Local actors are the target group of those policy approaches, and the question arises of if and how much those actors are consulted or even integrated into the design of local land use and protection policies. This article addresses this question by comparing seven different case studies in Swiss mountain regions. Through a formal social network analysis, the inclusion of local actors in collaborative policy networks is investigated and compared to the involvement of other stakeholders representing the next higher sub-national or national decisional levels. Results show that there is a significant difference (1) in how local actors are embedded compared to other stakeholders; and (2) between top-down versus bottom-up designed policy processes.  相似文献
