In rainfed production systems throughout India, agricultural activities are dependent upon the summer monsoon, and any aberration in monsoon rainfall patterns can have severe consequences for rice production. There is considerable policy interest in designing programs to lower small‐scale farmers’ exposure to these types of risk given the regularity with which adverse monsoon events occur. This paper introduces a field experiment conducted with two risk management options in the state of Odisha: a drought‐tolerant rice cultivar; and a weather index insurance product designed to complement the performance of the cultivar. Uptake rates for the cultivar itself and for the joint product are compared across two years alongside an analysis of factors that predict uptake. Results indicate high levels of demand for both the products, albeit with a significant degree of price sensitivity. But this sensitivity is agnostic to the nature of price reductions, suggesting that public investments that lower the costs of risk management may be sufficient to encourage broad uptake, without necessarily relying upon distortionary subsidies as is so often done. Sustained demand between years one and two is primarily explained where individuals were indemnified in year one and had a large number of peers also purchasing the product.  相似文献

Subsistence farmers in Lesotho have been able to boost agricultural yields and increase food production by adopting conservation agriculture. The practice, locally known as likoti, also contributes to combating soil erosion and to enhancing fertility. The socio-economic and environmental benefits help poor households to rehabilitate and strengthen their livelihood capital base and ultimately help rural communities to build system resilience in the face of widespread poverty and increasing vulnerability that affect the country. This paper discusses the major advantages associated with the spread of likoti. By drawing on primary data collected by FAO-Lesotho, it enquires into the determinants of adoption, thereby highlighting constraints and options for future up-scaling. The results show that attending appropriate training is a crucial prerequisite for the correct adoption of likoti. However, training is more effective when trainers pursue true participation and when social capital among farmers is stronger. Further important determinants of adoption are the level of education and the economic incentives provided to vulnerable households. Stronger policy and institutional support in all these areas would thus help address the cultural and resource constraints that limit the full potential of likoti to be harnessed and ultimately hinder its further spread throughout the country.  相似文献

Smallholder farmers in developing countries face a competitive disadvantage in modern agricultural supply chains. Joint marketing through cooperatives is a potential tool to mitigate these disadvantages; yet cooperatives’ success in these settings is uneven at best. We develop an analytical model to study a farmer's choice of selling to a private trader who pays cash on delivery but may exercise market power or a cooperative that promises a price premium but delays payment and carries a concomitant risk of default. In the presence of impatient and risk‐averse farmers, we show that these factors can severely limit smallholder patronage of a cooperative, despite a promised price premium. We then construct and parameterize a simulation model to fit a profile of heterogeneous farmers within a prototype developing‐country village, and study the optimal decisions of farmers regarding marketing through a cooperative versus a private trader. Results suggest that modest improvements in either timeliness of payment or probability of default can induce a substantial increase in a cooperative's market share and economic viability. Extending the simulation analysis to a dynamic setting shows how implementing reasonable policies to improve a cooperative's payment timeliness and default probability can markedly improve its growth trajectory.  相似文献

Leguminous agroforestry (AF) species have been investigated and promoted in Malawi as a means to improve soil quality and maize (Zea mays) yields. Our objective was to determine whether AF systems' recommendations that solely consider impacts on average maize yields differ from those that include an analysis of production risk, profitability among different wealth groups and socioeconomic vulnerability. Employing participatory quantitative and qualitative on-farm research techniques, we investigated three AF-based maize/legume relay-cropping practices in southern Malawi. The perennial legumes included Sesbania sesban, Tephrosia vogelii and Cajanus cajan (pigeonpea). We found that AF species recommendations did diverge from those based solely on maximizing maize yields when incorporating risk, profitability and socioeconomic vulnerability as additional variables. For instance, the highest yielding system (the S. sesban/maize relay crop) was never recommended for the most vulnerable farmers based on the vulnerability analysis, and the cropping systems were often more profitable for the least vulnerable farmers than they were for the most vulnerable farmers. Cropping system recommendations based solely on obtaining the highest average maize yields would also have generally overlooked the economic and nutritional importance of pigeonpea, and the difficulty for the most vulnerable farmers to profit from fertilizers, potentially placing these farmers at greater risk.  相似文献

Integrating adaptation and mitigation response actions to climate change in urban-level policies requires comprehensive information on vulnerability patterns, yet a majority of local governments and decision makers in various cities in developing nations lack spatially explicit information on climate change vulnerability and its key drivers. In addition, there is no standardised method for an all-inclusive vulnerability assessment at the local level. Results from higher broad-scale vulnerability assessments are difficult to implement conceptually and technically at the local scale. We present a climate change vulnerability assessment approach at the city scale that considers three main components: exposure, sensitivity and adaptive capacity. Indicators were assessed within each component and were combined using Spatial Multi-Criteria Evaluation (SMCE). The standardisation of indicators under each component was conducted, along with weighting, at each level of the vulnerability assessment hierarchy. The vulnerability assessment approach was applied to an urban area in India; namely, Bangalore metropolitan area. The application of vulnerability assessment approach was demonstrated and a spatial assessment of climate change vulnerability patterns was presented. The spatial pattern of vulnerability identifies areas urgently requiring attention to adaptation action, while vulnerability assessment enables policy intervention and prioritization at local spatial scales. This study presents a rational to integrate vulnerability assessment approach within the urban planning realm in Bangalore metropolitan area where according to our study approximately 91% of the area is facing high degree of climate vulnerability.  相似文献

Variety change and genetic diversity are important means of combating crop losses from pests and diseases in modern agricultural systems. Since the Green Revolution, genetic diversity among wheat varieties released in India has increased but variety change on farms continues to be slow. In this article, we define and summarise indices of variety change and genetic diversity for the wheat varieties released and grown in Indian Punjab during the post‐Green Revolution period. We evaluate the effect of each index on technical efficiency with a Cobb‐Douglas yield model after testing for exogeneity. Findings support the hypothesis that slow variety change has offset the positive productivity effects of diversifying the genetic base in wheat breeding during the post‐Green Revolution period. Policies that speed the rate of variety change and contribute to a more equitable spatial distribution of modern varieties could support wheat productivity in the Punjab of India, reinforcing plant breeding successes.  相似文献

The increasing magnitude and frequency of landslide-related disasters exposes weaknesses in disaster risk reduction (DRR) policy. One of the underlying reasons is that DRR policies tend to focus only on the physical aspects of the problem (i.e. mass movement processes) while neglecting the level of vulnerability of exposed populations to landslide threats, which affects the types and magnitude of adverse consequences. This neglect is a typical symptom of the remoteness that can exist between public administrators and local communities and undermines the implementation of participatory risk management. Certain dimensions of vulnerability depend on how communities relate to the issue of disasters based on their intuitive or rational judgment, i.e. their perception of risk. This paper seeks to shed light on the need for an understanding of risk perception based on the findings from a survey of residents in the city of Angra dos Reis, Rio de Janeiro, Brazil, to be taken into account in aiming at a more efficient landslide risk management policy. The survey was carried out through semi-structured face-to-face interviews with residents of three typical hillside communities in this municipality. In general, the study found that residents will often weigh landslide risks against other threats and opportunities existing where they live. It also found that community members find it difficult to see themselves as agents of change in the environment where they live and in mitigating landslide risks, and that better communication is needed between the government agencies involved in risk management and local residents.  相似文献

Using long-term district-level climate data and a case study from a drought-prone village in western Bangladesh, this research explored trends in climate change, and analysed farmers’ adaptation dynamics, profitability and risks. This is the first study of its kind for drought-prone areas in Bangladesh.Farmers perceived climate changes included increases in temperature and decreases in rainfall which were as consistent with the trends of Chuadanga climate records. Farmers’ adaptation measures included changes in cropping systems, cropping calendars, crop varieties, agronomic practices, crop diversification and improved animal husbandry. Reducing environmental stress, ensuring self-sufficiency in staple crops (mainly rice) and other crop production practices, and enhancing economic viability of farm enterprises have underpinned these adaptations. Off-farm and non-farm wage employment, temporary migration, self-employment and educating children, constituted the core non-farm adaptation strategies.Emerging cropping systems like maize/cucumber and maize/stem amaranth/rice were economically more viable than the traditional rice/rice and rice/maize systems. Despite some uncertainties, farming was preferred to off-farm work, generating higher returns to labour for all cropping systems. Limited access to stress-tolerant varieties, extension services and affordable agricultural credit, combined with high production costs, variability in crop yields and output prices, are the main barriers to adaptation. Stronger agricultural research and support services, affordable credit, community-focussed farming education and training are critically important for effective adaptation to climate change.  相似文献

China faces health and environmental problems associated with the use of agricultural chemicals, including pesticides. While previous studies have found that risk aversion affects pesticide use in China, they have focused primarily on commercial cotton farmers. In this study, we consider the case of smaller, semisubsistence and subsistence farmers in a poor and landlocked province of China (Yunnan). We use a field experiment to measure risk aversion and collect detailed data on farm production and input use to specifically ask whether risk aversion affects pesticide use, and whether this effect differs for subsistence farmers producing exclusively for home consumption versus semisubsistence farmers who produce both for home and the market. We find that risk aversion significantly increases pesticide use, particularly for subsistence farmers and for market plots by semisubsistence farmers. Further, this effect of risk aversion significantly decreases with farm size for subsistence farmers, but not for semisubsistence farmers, implying that pesticide use may be used to ensure sufficient food supply for home consumption. Finally, we find barriers to the use of pesticides for subsistence farmers, both in terms of financial constraints and economies of scale. This finding implies that risk‐mitigation strategies, such as crop insurance, may not target food security concerns of subsistence farmers. Given these different motivations for pesticide use, policymakers may wish to consider effective tools to support rural food security for farmers in the poorer regions of China in order to decrease pesticide use.  相似文献

This paper examines the effect of agricultural input subsidies (AIS) and agricultural extension services (AES) on farm labour productivity in plots planted with maize in Tanzania, using panel data from the National Panel Survey in Tanzania. To control for the endogeneity of the two programmes, a control function and instrumental variable approach is used to estimate the effects of AIS and AES on farm labour productivity. The results show that AIS and AES are significant in raising labour productivity in maize-planted plots. Similarly, AIS and AES are also effective in increasing land productivity in these plots. Moreover, each programme has comparable effects on land productivity and farm labour productivity. These findings imply that public investments in AIS and AES are effective in raising farm productivity.  相似文献

Many developing countries grapple with high rates of farmland degradation and low agricultural productivity amidst increasing climate variability. Considerable efforts have been exerted to promote the diffusion of improved farmland management to address these challenges. Despite these efforts, adoption rates, especially of soil conservation and water harvesting technologies, are still low, which has been the subject of investigation in several studies in Ethiopia and elsewhere. Most studies on the adoption of these technologies, however, tend to focus on economic incentives only, paying little attention to the role of social capital. This article provides evidence of the effects of different dimensions of social capital on innovation adoption across households holding different levels of risk aversion. We address this issue by using cross section and panel data from Ethiopia. Results show that social capital plays a significant role in enhancing the adoption of improved farmland management practices. We also find evidence that the effect of social capital across households with heterogeneous risk taking behavior is different.  相似文献

The impact of multinational firms on the domestic agricultural sector in developing countries is controversial, in particular in India. Relying on a unique set of household‐level data from the state of Punjab, we study the biggest dairy company in the world (Nestlé) in India and compare its vertical spillover effects on upstream suppliers to other market channels (informal sector and cooperatives). We find that farmers that supply informal channels are less efficient and earn lower profits per dairy animal than farmers supplying the cooperative and the multinational sector. Furthermore, we find that farmers using the multinational channel are more efficient than farmers in the cooperative channel, but equally profitable. Hence, we do not find that supplying the cooperative channel is more beneficial for local dairy farmers than supplying the multinational channel. Overall, however, dairy productivity and profitability levels are still dramatically low, with substantial scope for dairy development.  相似文献

Tree species richness, diversity index, standing biomass and biomass carbon stocks were estimated in six villages located under three agro-ecological zones, namely, coastal, hill and plains of Uttara Kannada district, Western Ghats, Peninsular India. The study showed that land use categories other than forest support higher tree species diversity. High basal area, standing biomass and carbon stock in non-forest land categories indicates their potential as carbon sinks and for promotion of species diversity. Inclusion of other non-forest land use categories in afforestation programmes for promotion of multipurpose tree species for conservation of diversity and for enhancing carbon sinks is suggested. There is a need to promote synergy between biodiversity conservation and carbon sequestration under carbon mitigation projects.  相似文献

In this paper we investigate the presence of productivity convergence in eight regional pulp and paper industries of U.S. and Canada over the period of 1971–2005. Expectation of productivity convergence in the pulp and paper industries of Canadian provinces and of the states of its southern neighbour is high since they are trading partners with fairly high level of exchanges in both pulp and paper products. Moreover, they share a common production technology that changed very little over the last century. We supplement the North-American regional data with national data for two Nordic countries, Finland and Sweden, which provides a scope to compare the productivity performances of four leading players in global pulp and paper industry. We find evidence in favour of the catch-up hypothesis among the regional pulp and paper industries of U.S. and Canada in our sample. The growth performance is at the advantage of Canadian provinces relative to their U.S. counterparts. The two Nordic countries, that had the lowest productivity levels in 1971, erased most of the gap and in some cases moved ahead of their North-American counterparts.  相似文献

This article focuses on the intermediary figure of the village‐level petty retailer of chemical inputs, providing an account of the everyday relationships of farmers with transnational and domestic agribusiness capital. Retailers are figures from whom farmers purchase seeds, fertilizers, pesticides, and other chemicals. The article traces the rise of village‐level retailers in western Maharashtra, India, since the 1990s, and finds that Maratha (a dominant landholding cultivator caste) households have ventured into retailing. Further, farmers depend on retailers for credit, technical knowledge, and for the sale of their harvest. By analysing the pressures and risks of petty retail, visible in interactions with farmers, the article argues that even as retailing provides avenues for upward mobility to petty agricultural commodity producers, the trade is too volatile for the gains to sustain. Thus, the entry of Marathas into petty retail is akin to an attempt at class differentiation but without consolidation.  相似文献

The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and other actors in the agricultural sector. But there are still unanswered questions about whether emerging and evolving seed policy reforms and IPR regimes in developing countries will contribute to increasing crop productivity and improving food security. This paper attempts to answer some of these questions by focusing specifically on the case of India, the regional leader in implementing seed policy reforms and IPRs in agriculture. Findings indicate that maize and pearl millet yields grew significantly during the last two decades due partly to the combination of (1) public policies that encouraged private investment in India’s seed industry during the 1980s, and (2) biological IPRs conferred by hybridisation that conveniently married the private sector’s need for appropriability with the nation’s need for productivity growth. Although past lessons are not an indication of future success, this convergence of policy solutions and technology opportunities can be replicated for other crops that are vital to India’s food security.  相似文献

The inventory of muddy floods in France indicates that the occurrence of these events seriously increased in the North West and the East of the country. Muddy floods triggering can largely be explained by physical characteristics such as a hilly topography, soils prone to crust, and/or heavy rainfall in spring. Although the physical processes are well known by now and despite increasing information about the need of mitigation measures, no significant reduction of these disasters has been registered. Therefore, this should be explained by factors others than scientific reasons or technical knowledge acquisition difficulties.  相似文献

The management of flood risk in Europe is changing. In several European Member States there are significant ongoing processes to shift certain flood risk management duties and responsibilities from the national to the local level. Previously, national authorities dominated the discourse about national flood risk management policy, but increasingly, local and private stakeholders have become responsible for flood risk management. This has greatly influenced the governance structure and arrangements for flood risk management policy. As a result, the co-operation among various stakeholders has become increasingly important. The consequences of this shift toward local stakeholders can be understood in the context of rescaling. This paper analyses the rescaling processes through catchment-wide management plans in the Austrian flood risk management system. Therefore, we selected three different Austrian study sites (Aist in Upper Austria, Triesting-Tal in Lower Austria and Ill-Walgau in Vorarlberg). New management ideas required new dynamics within the current scales and allowed changes in the interaction of local, regional, and national stakeholders in terms of negotiation, funding, and strategy development. The new policy direction demonstrates not only the importance of network connections between stakeholders at the same scale, but also networks between stakeholders at different scales, especially between local and national levels. However, engagement at the local level strongly depends on social capacities, such as knowledge, motivation/self-interest, networks at various levels, and procedural capacity. The theoretical framework of politics of scale helps in understanding and analysing the impact of the new decentralisation policy and practice.  相似文献
