Russia's agriculture produces around 3.7 per cent of the country's GDP, employs 9.2 per cent of the national workforce and contributes around 6 per cent of the country's exports. The sector has shown remarkable resilience in the face of wider economic turbulence. Self‐sufficiency rates for the main agricultural commodities are relatively high. Agricultural exports have grown very significantly since 2000 especially for wheat and meslin (wheat and rye mixture). Meat production has been growing steadily, particularly in the poultry and pork sectors. Whilst the agri‐food sector has great potential to play an even more prominent role in Russia's economy, it suffers from relatively low productivity and an outdated technological base. The main drive for efficiency has come mainly from the relatively large‐scale agricultural firms, who generated more than half of the total value of agricultural output in 2016. Foreign policy instability, including economic sanctions, the devaluation of the national currency and declining economic growth have weakened the sector and caused an increase in the prices of imported goods and equipment. At the same time Russian products have replaced high value‐added imports and Russia's agricultural producers are expanding into new markets.  相似文献

Contractual agreements between smallholder farmers and agribusiness companies have gained in importance in many developing countries. While productivity and income effects of contracting in the small farm sector were analyzed in many previous studies, labor market and employment effects are not yet well understood. This is an important research gap, especially against the background of continued population growth and structural transformation. Here, we investigate the effects of two types of contractual agreements between large international processing companies and smallholder farmers on agricultural labor use, household labor allocation, and hired labor demand in Ghana's palm oil sector. We use cross‐sectional survey data and a willingness‐to‐pay approach to control for unobserved heterogeneity between farmers with and without contracts. We find that agricultural labor intensity is substantially reduced through the contracts, because contracting in Ghana is associated with the adoption of labor‐saving procedures and technologies. Simple marketing contracts lead to reallocation of the saved household labor to off‐farm employment, whereas resource‐providing contracts lead to a stronger reallocation of labor within the farming enterprise. Household labor is more affected by labor savings than hired labor.  相似文献

With the global restructuring of agri‐food markets since the 1980s, an impressive amount of scholarship has examined its impacts in African countries. However, little has been written on the emergence of local medium and large‐scale commercial farmers selling to export companies or controlling their own export marketing arrangements. This article examines Ghanaian commercial farmers producing and exporting fresh pineapples to European markets. This group of pineapple producer–exporters represents a path to capitalist agricultural production that can be conceptualized as capitalism from outside: where capital flows into the countryside, rather than accumulation occurring from above or below within the agrarian economy. The emergence of this form of agrarian capitalism is stimulated by opportunities in new high‐value agricultural export markets, but its stabilization depends on country‐specific characteristics such as rural social structures, property rights and state support. The article documents the conditions of emergence of this new group of Ghanaian capitalist farmers, the period of destabilization caused by increasing international competition that resulted in a small number of large‐scale agribusiness firms surviving, and the challenges that these agribusiness firms faced in stabilizing their capitalist agricultural production.  相似文献

This article reviews the circumstances under which contract farming, as one form of vertical integration, is necessary to secure rapid and efficient co-ordination and adaptability within systems of food production/marketing/distribution. A review of American experience and attitudes indicates that contracting in the U.S.A. has been successful in matching farm production to the needs of consumers more quickly and economically than otherwise would have been possible. Contract terms have generally been ‘fair’ to United States farmers, partly as a result of a strong co-operative system, including a large number of bargaining co-operatives, but also as a result of strong competition between American agri-businesses. American experience and conclusions can be transposed to British circumstances. However, there should be greater publicity and analysis of contract terms, as well as more complete information on the financial performance of the agri-business operations of conglomerates and other multi-product businesses.  相似文献

This paper reports the findings of a study whose objectives were to compare and contrast the public and private sectors in Asia in terms of their (1) estimated level of investment in maize breeding research; (2) germplasm outputs; and (3) nature and extent of roles played in the maize seed industry. Since the 1960s, yield gains, rather than area expansion, have fuelled increases in maize production in Asia. Yield gains, in turn, have been due to the shift in maize cultivation from mostly open‐pollinated varieties (OPVs) to mostly hybrids. This transition also shifted the locus of modern maize breeding research from government research organisations to private national and multinational seed companies. In countries where both the public and private sectors participated in maize research, private sector research investment far exceeded that of the public sector. With more aggressive marketing programmes, the private sector captured 89% of the Asian maize seed market in the late 1990s. National public seed research agencies (including universities and cooperatives) developed and produced more maize OPVs than hybrids, mass‐produced and distributed seed cheaply, addressed location‐specific production problems, and provided agricultural extension services. The private seed companies developed, produced, sold and promoted their own proprietary hybrids. The reluctance of the private sector, however, to address the needs of marginal maize farmers should encourage the public sector to continue playing an active role in maize research and development (R&D), seed production and modern maize technology dissemination, especially with adequate support from appropriate government policies.  相似文献

This paper explores how agricultural technology has interacted with recent land use in the UK and how it might do so in the next 50 years. From 1960 to 1985, farmers successfully used technology to increase the output of crop and animal products per unit of land and particularly of labour. This reduced the number of people employed in agriculture, and promoted larger and more specialised farm enterprises. Between 1985 and 2006, food prices were relatively low, and although labour productivity continued to increase, land productivity remained relatively static. However during this period, farmers started to address the effects of agriculture on reduced water quality and habitat loss.For established agricultural products, technological innovation tends to have an incremental effect, working through genetic improvement, the removal of abiotic and biotic stress (e.g. crop nutrition and protection, irrigation and drainage, and animal nutrition, health and housing) and the substitution of labour. Whereas the first two processes tend to be scale-neutral, the substitution of labour is usually easiest to achieve on larger farms. Other key areas for technological innovation include addressing air, soil and water quality, biodiversity, waste reduction, and information management. Over the next 50 years, large step-changes in land use arising from agricultural technology are predicted to arise from the development of new markets for agricultural products. A strong bioenergy sector will strengthen the links between crop commodity and energy prices and will have a major effect on future land use. Climate change and the regulation of greenhouse gas emissions will alter the relative profitability of crop and animal production systems. Lastly, increased public awareness of the links between food, health and the environment could substantially shift the demand for specific agricultural products.Continual improvements in agricultural technology are pivotal to providing society with the flexibility to balance the challenges of improving human well-being with the management of the planet's ecosystem. Increased technological innovation increases the probability that agricultural land can be used for other purposes, but the exact relationship is dependent on trade and environmental policies. The large external effects of agriculture mean that decisions regarding the adoption of future technologies should be taken by farmers working with other stakeholders.  相似文献

The aim of this study is to determine whether the evolution of Spain's agrarian change, between 1950 and 2005, exhibits any features important enough to differentiate it from the common model of developed countries in Western Europe. On the one hand, the Spanish agrarian transformations share the main features of the changes in Western Europe: technological innovation, increased production and productivity, the diminishing importance of the agricultural sector, close integration with the industrial sector, and a high environmental impact. On the other hand, a series of important peculiarities can be observed in Spain's agrarian change: strong expansion of intensive livestock farming; the role of increased irrigation in explaining the transformation of agriculture; policies that offered very little support to the agricultural sector under a dictatorship that denied a voice to farmers; and the prominent role of agriculture in the economy despite its small contribution to GDP.  相似文献

The modernization and intensification of agricultural production in Africa has long been a policy goal, for increased productivity and food security. In 2008, the Rwandan government implemented various land and agricultural reforms to transform Rwandan agriculture from subsistence farming to market-oriented production. Central to this agricultural transformation was the Crop Intensification Programme, intended to increase the agricultural productivity of high-potential food crops and encourage land use consolidation, i.e., the joint cultivation of large areas, which was expected to deliver important economies of scale. This programme has been criticized, for example, for authoritarian implementation, negative effects on food security from sole-cropping a few selected crops, and increasing rural socioeconomic differentiation.This paper analyses the effects of the land use consolidation programme at the household level, as experienced by small-scale farmers in Musanze District in the Northern Province of Rwanda. The paper draws on 45 individual and 22 collective qualitative semi-structured interviews with small-scale farmers and local key informants in five sectors, conducted in 2013 and 2014.The findings show that there is satisfaction, dissatisfaction, and resistance to the programme, especially regarding the selected crops to be cultivated. The programme, including supporting mechanisms, seems to work well for the relatively better-off farmers, who have bigger and scattered land areas, whereas it does not work well for poor farmers with very small plots, which is common in rural Rwanda.  相似文献

The Australian agricultural sector provides food security for the nation and affects the livelihood of farmers and the development of rural communities. This sector has been uneasy about the Australian carbon tax scheme introduced in July 2012 although the government has exempted the agricultural sector from the scheme. By employing a computable general equilibrium model and an environmentally extended Social Accounting Matrix, this article simulates the effects of different carbon tax policy scenarios. The modeling results show that all agricultural sectors will be affected negatively but to differing degrees. The household compensation policy will improve the performance of the poultry and fishing sectors, while having opposite effects in the other agricultural sectors. The inclusion of the agricultural industry into the carbon tax scheme will lead to a considerable further decrease in output, employment and profitability in the agricultural sector, and a significant further reduction in real GDP, but a much larger emission reduction.  相似文献

African countries continue to face deepening food crises that have been accentuated by the global food, energy, and financial crises. This situation is part of a long‐term structural problem: decades of under‐investments in agricultural sector and poor policies of support for smallholder farmers who form the bulk of the farming population. The inability of these farmers to achieve a supply response when commodity prices were high and market access was less of a problem suggests that there are multiple sets of binding constraints that continue to limit the potential of agricultural growth to reduce food security and poverty on the continent. This article reviews some of the historical trends that have hampered the performance of the agriculture sector. In addition, it reviews the impacts of more positive trends that could stimulate agricultural growth in Africa that could change the African agricultural landscape. The article however warns that there are more recent global developments and some continental challenges that could prevent or slow agricultural growth. These include the global financial crisis, public sector investments, inequities in global agricultural development policies, rush for agricultural lands by foreign investors, domestic commercial financing markets, climate change, and emerging carbon markets. The article argues that while opportunities for accelerated growth exists for African agriculture, new sets of policy instruments will be needed to support smallholder farmers to access new agricultural technologies, finance, reduce impacts of climate change, and adopt sustainable land use practices that can allow them to benefit from emerging global carbon markets.  相似文献

Marketing is an important and challenging competitive instrument for small-scale quality food producers. Traditional commercial channels may be unprofitable and small-scale food producers often lack access to a highly concentrated retail sector. In this situation a number of strategic alliances between farmers and between farmers and other public and private actors have emerged. The aim of this paper is to discuss and compare initiatives to develop alternative marketing channels for small-scale specialty food producers. The three examples of emerging channels we investigate are (i) the 'new' farmers markets, (ii) retail initiatives where local producers deliver their produce directly to shops, and (iii) companies founded by large cooperatives to market specialty products. Recent research has justified that such initiatives can be conceptualized as hybrid governance structures, i.e. complex structures that entail properties of both market and hierarchy. We pay particular attention to the problem of quality enforcement in emerging marketing channels.  相似文献

The food crisis in Africa has entered our living rooms through television and the press. Why is per capita agricultural production lower now than at independence in the early 1960s? This article examines the factors responsible and outlines some solutions. Both external and internal factors have converged to create the crisis - low prices to farmers to placate vocal urban consumers, inefficient, high-cost marketing boards, governments' neglect of agriculture in favor of industry, over-valued exchange rates, lack of foreign exchange and increasing debt burdens. Externally the depressed world market decreased demand for Africa's exports and contributed to the stagnation of the economics. Drought, a population growth rate approaching 3%/year and a shortage of human capital added to the crisis.  相似文献

The 2003 Mid‐Term Review of the CAP sought to refocus the EU's farm support policy to foster a more competitive and market‐orientated agricultural sector. The foundation of this reform comprised the introduction of decoupled payments to farmers, replacing the EU's previous system of supports that were directly linked to production of designated crops and livestock. This paper explores the effect of coupled payments and their subsequent replacement by decoupled support, on the technical efficiency of specialist beef farms in Ireland. Given the high reliance of beef farmers in Ireland on CAP payments, the decoupling of payments has been especially important for the sector. A stochastic production frontier is estimated using a panel dataset comprising detailed accountancy data for Irish beef farms between the years 2000 and 2013. Our results indicate that technical efficiency in the beef farming sector has been consistently poor, with an average efficiency score of only 0.53 during the period analysed. However, we found that direct income received in the form of coupled payments had a positive impact on farm efficiency, and that this positive effect was maintained after their replacement with decoupled income support.  相似文献

This report empirically examines the role which capital accumulation plays in the growth of agricultural production potential. The report assumes that the degree to which available technology can be implemented in a nation's agricultural sector depends on accumulated investments that have been made in the sector. Results from estimating aggregate agricultural production functions show the primary importance of rural labor in accounting for agricultural gdp and crop production. Capital accumulation is the dominant explainer of livestock production. Estimation results support the conjecture that capital tends to save scarce land resources (substitute relationship) and use rural labor (complementarity relationship). Output supply elasticities derived from the estimated equations tend to be large. The large elasticities imply that price distortions have had large impacts on resource use and production.  相似文献

Small-scale farmers are known to produce the greater proportion of food consumed in the Third World, especially in sub-Saharan Africa. The various national and international agricultural research centres located in these parts of the world have developed agricultural packages which have been proven, at experimental levels, to be highly productive. However, small-scale farmers in these areas continue to produce at levels far below the capacities of these packages as predicted from experimental results. Consequently, these farmers, despite their relatively large number, could not produce enough to feed themselves let alone the general population. To improve the quality of life of these farmers in particular, and the population of the Third World in general, there is a need to study the various factors responsible for low agricultural production at the household level. Models relating production to the various factors need to be formulated to improve our understanding of the functional relationships. This in turn could lead to relevant national and international policies with respect to small-scale farmers in the Third World. In this paper, we develop models to predict production given these factors. For simplicity, the parameters of the models are limited to land size (or herd size), environmental effect and management effect. A statistical examination of our model fitted to a set of survey data on this subject revealed that improving the farmers' management level could greatly enhance their production. Further statistical analysis of the data set showed that the various factors constituting the farmers' management level could broadly be classified into three groups: resources (labour and farm implements), personal characteristics (educational level and age) and external assistance (contact with extension agents/assistance) in that order of importance. We discuss the importance of these findings in the formulation of policies concerning small-scale farmers in sub-Saharan Africa.  相似文献
