Irrigation expansion is critical to increase crop yields and mitigate effects from climate change in Sub‐Saharan Africa, but the low profitability has led to little irrigation investments in the region so far. Using an integrated modeling framework, we simultaneously evaluate the returns to irrigation arising from both economic and biophysical impact channels to understand what determines the profitability of irrigation in Malawi. Our results confirm that the returns to irrigation cannot cover the costs in Malawi. While labor‐intensive irrigation expansion leads to unfavorable structural change in the short‐run, the profitability hinges on low irrigated yields that fall far from expectations due to insufficient input use and crop management techniques. On the other hand, we find that the nonmonetary benefits of irrigation regarding higher food security, lower poverty, and reduced vulnerability to climate change make investments in irrigation worthwhile to improve the livelihoods of smallholders.  相似文献

South African agrarian policy aims to integrate smallholder tree‐crop farmers into high‐end value chains with growth and employment potential, generally neglecting socio‐economic differentiation amongst them. This paper aims to analyse socio‐economic differentiation amongst tree‐crop farmers in Vhembe District, Limpopo, using a class‐based analysis based on livelihood diversification and accumulation. Cluster analysis of survey data and semi‐structured interviews reveals that most tree‐crop farmers engage in petty commodity production, internally differentiated by their combination of income sources and livelihood strategies. Farmers' ability to engage in accumulation and upward class mobility is generally severely constrained by limited access to capital. Agricultural diversification offers livelihood potential but limited possibility for accumulation, whereas salaried nonfarm work offers more promising prospects for accumulation but limited livelihood opportunities. A minority demonstrated characteristics of small‐scale capitalist farmers, internally differentiated by their reliance on salaried employment or agricultural production. The findings challenge the notion of an undifferentiated class of market‐oriented smallholders.  相似文献

Using panel data from 256 smallholder households from 2006 to 2014 in three semiarid regions India, this study develops a framework for quantifying vulnerability and resilience by accounting for a smallholder household’s ability to adapt and respond to climatic risk. Findings indicate that although smallholders with smaller landholdings are more vulnerable to climatic risk (drought, in our case), they are also more resilient than their counterparts. Results reveal that cropping intensity and crop risk increase the vulnerability of smallholders to climatic risk, but large farms are less vulnerable. Diversification in on-farm enterprises, like livestock units, and off-farm income sources, play significant roles in increasing smallholder households’ resilience to climatic risk. Other drivers of resiliency include the choice of cash and risky crops, borrowing capacity, liquid investments, and the ability to regain yields.  相似文献

In this paper, we analyse how smallholder farms have evolved during the transition process in former communist countries and how this process has differed across countries and commodities. The role of smallholders in agriculture differs among transition countries, and this diversity is due to a combination of factors, including capital, labour and land endowments, income levels, scale economies, market imperfections, and reform choices. Institutions to access inputs and sell outputs affect the efficiency and survival of smallholders. In the past decade, the share of smallholders in land use and production has declined significantly as younger and more dynamic smallholders have become integrated in modern value chains, whereas older, less dynamic farmers have (semi‐)retired, producing only for household consumption.  相似文献

Cotton farmers in many developing countries are facing decreasing marginal returns due to stagnating yields and high input costs. Conversion to organic management could offer an alternative. In a two year comparative study in central India covering 170 cotton fields, organic farms achieved cotton yields that were on par with those in conventional farms, whereby nutrient inputs and input costs per crop unit were reduced by half. Due to 10–20% lower total production costs and a 20% organic price premium, average gross margins from organic cotton fields were 30–40% higher than in the conventional system. Although the crops grown in rotation with cotton were sold without premium, organic farms achieved 10–20% higher incomes from agriculture. In addition to these economic benefits, the organic farming system does not burden soil and groundwater with synthetic fertilizers and pesticides. However, in this study only minor differences were detected in soil fertility parameters of organic and conventional fields. Altogether, the results suggest that conversion to organic farming can improve livelihoods of smallholders while protecting natural resources. Income loss due to reduced yields in initial years of transition, however, constitutes a major hurdle, especially for poorer farmers. It is thus important to support farmers in overcoming the obstacles of the conversion period.  相似文献

In 2013, Ethiopia's Agricultural Transformation Agency introduced the Wheat Initiative to increase smallholder productivity. In this article, we measure the impacts of the Wheat Initiative package of technologies, and its marketing assistance component alone, on yields among a promotional group of farmers. The package includes improved techniques, improved inputs, and a guaranteed market for the crop. Relying on crop‐cut measures and farmers’ own assessments, we find that full package led to an average 14% higher yields. Implementation of the Wheat Initiative was successful in making certified seed and fertilizer accessible to farmers and increasing their uptake, though only 61% of the intervention group adopted row planting and few farmers received marketing assistance. The measured yield difference may underestimate the true yield difference associated with the technology because of incomplete adoption of the recommended practices by intervention farmers and adoption of some practices by control farmers.  相似文献

A component-omission experiment based on the principle of conservation agriculture (CA) was established on smallholder farms for three seasons in Murehwa and Hwedza districts, Zimbabwe; Barue district in Mozambique; Balaka district and Chitedze Research Station in Malawi, and Monze district in Zambia to identify strategies for improving crop productivity and livelihoods for smallholder farmers. The objective of the experiment was to evaluate the effect of tillage, residue retention, fertiliser application and weed control on maize yield. In addition, the study analysed possible combinations of these factors that could provide a sustainable entry point for intensification through CA. Results showed that fertilisation had the strongest effect on crop yield in both tillage systems; adequate fertilisation is therefore key to success in CA. Retention of crop harvest residues increased yield in no-tillage systems; no-tillage without residues depressed yield by 50% when compared with yields of conventional tillage. A step-wise integration of CA into the smallholder farming systems is proposed as a possible strategy to avoid new constraints on smallholder farms. If resources are limiting, farmers may apply all principles on small areas to overcome the initial demand in resources (labour, fertiliser and residues), and once productivity is raised, they can expand.  相似文献

Index‐based weather insurance is increasingly used to manage weather‐related risks in smallholder agriculture. However, cash‐constrained smallholders often lack the resources to pay an insurance premium, which may undermine its wider adoption. This article investigates alternative insurance payment methods that may help to enhance the adoption of index‐based weather insurance. We use a choice experiment to elicit smallholders’ willingness to pay in cash or labor for index‐based weather insurance in four districts in the south‐central highlands of Ethiopia. The insurance schemes were created using a fractional factorial design with three factors: work, cash, and payout rate. We analyze the choice data using a random parameter mixed logit model. We find that the average participants need a subsidy to pay cash for insurance because their willingness to pay is less than the expected cost of the insurance. On average, they are willing to pay only 0.81 ETB (Ethiopian currency) to get an expected yearly payout of 1 ETB. However, most are willing to participate in work‐for‐insurance programs at lower daily wage rates than is common for other work programs in Ethiopia.  相似文献

Tanzania is a net importer of dairy products despite its large cattle herd and successive government efforts to promote dairying. This paper draws on survey data to examine the financial attractiveness of dairying to smallholders in an area of high dairy potential on the slopes of Mount Kilimanjaro. On mixed farms in which coffee and bananas are the other main enterprises, producers keep small herds of mainly crossbred and grade cattle, mostly fed in stalls on cut forage and crop residues. Using a herd model, a benefit-cost analysis of dairying was carried out. This showed that at prevailing prices, returns to dairying were around 20%. There was, however, no difference in the returns gained by the larger scale farmers who had more of the grade cows and managed them intensively, compared to those using a less intensive system with lower potential stock. Moreover, the profitability of dairying for the former was underwritten by subsidies on inputs and fuel which are difficult to justify. Policy has apparently over-emphasised improving yields and the development of intensive dairying, and has not been sufficiently concerned with keeping down the costs of dairying.  相似文献

Many tropical regions are experiencing a rapid growth of oil palm cultivation. In Indonesia, the world's leading palm oil producer, in addition to large companies, smallholder farmers are increasingly engaged in the oil palm sector. Smallholder oil palm cultivation may contribute to income gains and socio‐economic development. However, land‐use decisions by smallholders are not well understood. Without appropriate policies, negative social and environmental consequences can also occur. To improve the knowledge base, we use data about present and past land‐use decisions from a survey of farm households in Sumatra. Employing duration models, we analyse the determinants and dynamics of oil palm adoption among smallholders. We find that independently operating farmers are currently driving growth rates in the oil palm sector. Smallholder adoption decisions are mainly attributable to regional and village level factors. While the current adoption primarily occurs outside of contracts, previous contractual ties between companies and other farmers in the same village play an important role for individual decisions. Beyond initial adoption, we also analyse later expansion decisions. While expanding the oil palm area subsequent to initial adoption is common among all types of adopters, those without previous contracts are found to expand significantly faster. We conclude that the concessions the government has allocated to palm oil companies in the past have initiated oil palm adoption in the small farm sector, but that the ensuing land‐use dynamics are mostly beyond government control. Some wider implications are discussed.  相似文献

Medic (Medicago spp.) pastures are widely grown in rotation with dryland cereal crops in Mediterranean climate zones of Australia. Attempts since the 1960's to introduce this system to Mediterranean west Asia and north Africa (the native region of medic) have not lead to significant adoption; farmers in the region recognize medic, but as a weed and natural pasture plant. This first detailed economic evaluation of the rotational medic system was conducted using a whole-farm linear programming model based on the agricultural system of north-west Syria. The model represents in detail impacts of rotation on yields, labor requirements of alternative farm activities, availability of family and hired labor, subsistence income requirements, livestock feed sources and uses at different times and a choice of sheep stocking rates. Biological data for the analysis are based on a large six-year cropping and grazing experiment near Aleppo on terra-rossa soil with rainfall mainly in winter and averaging about 330 mm annually. The trial compared a dryland medic-wheat system and traditional two-year rotations of wheat with: fallow, watermelon, lentil and vetch. Results indicate that, given current prices and yields from the trial, medic is less profitable than traditional rotations. The model was used to investigate situations in which medic would be economically preferred. Selection of a medic rotation by the model was found to be particularly sensitive to the area of the farm and the price of labor. On small farms, labor availability per hectare is high, favouring the production of labor intensive crops such as lentil and watermelon. On larger farms, labor costs of these enterprises are substantial, increasing the relative profitability of medic, especially if labor prices increase. Interestingly, the relative desirability of medic is more sensitive to its impact on subsequent wheat crops than to the level of pasture production. We also found that modest increases in the prices of sheep products (especially milk) have a major impact on the economic performance of medic. These insights will allow improved focusing and targeting of future research and extension activities.  相似文献

Voluntary sustainability standards, aimed at improving the environmental, social and economic aspects of agricultural production and trade, are becoming increasingly common. The coffee sector is a prime example, where sustainability certification could improve livelihoods for poor smallholders. However, as individual production volumes are low, smallholder farmers need to cooperate in certification as a group, which makes impact assessment more complicated. Previous empirical studies, reporting premia of up to 30%, have neglected the costs associated with group certification. We explore the issue using an agent‐based simulation of coffee producer organisations in Uganda, including the certification‐related costs for farmers. Our results suggest that certification can have a small positive impact on participating households. But the added value of certification is substantially lower than the price premium, because of certification costs. Increasing both the membership of the producer groups and their deliveries of certified coffee are necessary to improve the rewards of certification.  相似文献

Transport costs are an important determinant of smallholder welfare in developing countries. In particular, transport costs influence the prices that smallholders receive for their produce. We propose a simple way of quantifying this influence. Taking the example of bean producers in Nicaragua, we employ a hedonic price model to estimate the effects of a smallholder's proximity to markets on the prices that he/she receives, while controlling for other factors such as the volume and quality of beans sold. We find that on average each additional minute of travel time reduces farm gate prices by 2.5 cents per quintal. Based on these results, the annual income from bean sales of the average smallholder in our sample would increase by between 24 and 110 USD if travel time to markets were reduced by 25%. Estimates of this nature can make an important contribution to cost–benefit assessments of infrastructure investments.  相似文献

Numerous alternative farming systems are proposed as solutions to the sustainability challenges of today's conventional farming systems. In this paper, we review the production, environmental, and socioeconomic performance of three widely discussed and promoted alternative farming systems—organic, smallholder, and urban agriculture. We show that both organic and smallholder agricultures have some benefits, but also entail important trade‐offs; organic has environmental benefits, and also livelihood, health, and nutritional benefits for producers and consumers, but is hampered by lower yields and higher prices. Smaller farms have higher yields and host higher biodiversity, but are hampered by lower incomes to farmers. Urban agriculture can take some pressure off rural landscapes, provide nutritional benefits to the urban poor, and engage urban dwellers in addressing food system challenges, but it simply cannot scale up to be a substantial solution in and of itself. We suggest that instead of focusing on alternative systems, we should identify pathways to sustainable farming for all systems, reforming conventional systems where they perform poorly, and transitioning to alternative systems in contexts where they perform best.  相似文献

This paper integrates aspects of global value chain and sustainable rural livelihoods analyses in an exploration of the local impacts of agri‐food globalization in Chile. In particular, it examines the evolution of the raspberry export sector in the context of Chile's non‐traditional agricultural export boom, and considers its importance to smallholder growers and rural households in central Chile. The paper first outlines the geography and structural configuration of the global value chain for Chilean raspberries, and considers modes of governance and forms of coordination between key actors within the chain. Second, the terms and implications of smallholder grower participation in the value chain are explored in a discussion of access to key livelihoods assets. The paper concludes that institutional support to smallholders, even in the case of a crop that is widely seen to have a small‐scale ‘size bias’, remains integral to their capacity to comply with required safety and quality standards and gain and retain market access via the value chain.  相似文献

The global demand for cashew nuts continues to increase steadily. However, many African countries face difficulties in marketing and adding value to the product. Using recent survey data of 391 cashew farmers in Ghana, this paper contributes to the growing evidence on the significance of contract farming (CF) in improving the welfare of rural households in developing countries. Specifically, the paper analyzes the factors that influence cashew farmers’ decisions to participate in CF, and the impact of participation on farmers’ performance. We employ a recently developed switching regression model with endogenous explanatory variables and endogenous switching to control for selection bias caused by observable and unobservable factors. The empirical results show that participation in CF significantly increases labor productivity and price margins, as well as cashew yields, and net revenues. A disaggregated analysis of the sample into farm size categories reveals that small‐sized cashew farms tend to benefit more through CF, compared to medium‐ and large‐sized farms.  相似文献

This study presents evidence of profound farm‐level transformation in parts of sub‐Saharan Africa, identifies major sources of dynamism in the sector, and proposes an updated typology of farms that reflects the evolving nature of African agriculture. Repeat waves of national survey data are used to examine changes in crop production and marketed output by farm size. Between the first and most recent surveys (generally covering 6 to 10 years), the share of national marketed crop output value accounted for by medium‐scale farms rose in Zambia from 23% to 42%, in Tanzania from 17% to 36%, and in Nigeria from 7% to 18%. The share of land under medium‐scale farms is not rising in densely populated countries such as Kenya, Uganda, and Rwanda, where land scarcity is impeding the pace of medium‐scale farm acquisitions. Medium‐scale farmers are a diverse group, reflecting distinct entry pathways into agriculture, encouraged by the rapid development of land rental, purchase, and long‐term lease markets. The rise of medium‐scale farms is affecting the region in diverse ways that are difficult to generalize. Findings indicate that these farms can be a dynamic driver of agricultural transformation but this does not reduce the importance of maintaining a clear commitment to supporting smallholder farms. Strengthening land tenure security of local rural people to maintain land rights and support productivity investments by smallholder households remains crucial.  相似文献

The policy literature on postsocialist Europe tends to frame smallholders' practices of food self‐provisioning and sharing as driven by necessity and proposes land consolidation to increase productivity and efficiency. However, these practices generate nonfinancial benefits, which need to be accounted for. In this paper, I test the socio‐economic relevance of these practices in the Republic of Moldova, the country with the highest density of farming households in Europe and whose government has embraced the rural modernization agenda to integrate into the EU economic space. I carry out quantitative estimates using the household budget survey and complement the results with qualitative insights from an original smallholder survey. I find that food self‐provisioning and sharing are positively related to subjective well‐being and that there is an “intergenerational pact,” with home‐grown food flowing from late‐adulthood smallholders to urban‐based young families and the vulnerable elderly. A counterfactual analysis shows that poverty and inequality would be higher in the absence of donated food, especially in urban areas. The preservation of smallholder farming through widespread access to land could thus help fight poverty and provide social benefits vis‐à‐vis land consolidation.  相似文献

Adoption of improved maize varieties in the hills of Nepal   总被引:3,自引:0,他引:3  
Maize (Zea mays L.) is the most important cereal crop in the hills of Nepal, where the grain is used for human consumption and the stover for animal fodder. Maize farms are small, and population pressure necessitates the intensification of existing farming systems. Maize research directed at developing technologies for maize production began in Nepal in 1965. In 2000, a survey was carried out in two districts to determine the current level of adoption of improved maize production practices. In each of these districts, remote and accessible village development committees (VDCs) were surveyed. Questionnaires were administered to 54 randomly selected households in each VDC. A Tobit analysis was used to determine socio‐economic, physical and technology factors that influence the use of improved varieties by farmers. All households use composted farmyard manure, and in the more accessible areas, urea as part of their soil fertility management strategy. Use of improved varieties was less than 60% for all VDCs and only 15% in the most remote VDC. In three of the four VDCs, adoption of improved varieties primarily occurred during the past 5 years. Based on a Tobit analysis, Khet land area, ethnic group, years of fertiliser use, off‐farm income, and contact with extension significantly and positively affected adoption of improved varieties. Farmers in VDCs in central Nepal reported lack of seed to be the major constraint to the adoption of improved varieties, while lack of knowledge of new varieties was the major constraint for farmers in the western VDCs. The results from this survey suggest that the strategy for improving the adoption of new varieties will differ depending on infrastructure and the socio‐economic conditions of the farmers in a given area.  相似文献
