How do African agricultural livelihoods change under stressful conditions? How do market and agricultural policies and development interventions impact on both agricultural and social change, and consequently on food self‐sufficiency? Which long‐term factors can contribute to ‘depeasantization’? Is the ‘New Green Revolution’ the best and only solution for African food insecurity? These are the main questions this paper sets out to address, using southern Guinea‐Bissau as a case study. On the basis of long‐term ethnographic fieldwork, we look at farmers' responses to external and internal pressures, and analyse how ‘depeasantization’ progresses and livelihoods have been losing their resilience. Chances to reverse this trend, although difficult to implement, may still be feasible.  相似文献

This paper takes the viewpoint of a social scientist and looks at agricultural scientists' pathways for science impact. Awareness of these pathways is increasingly becoming part and parcel of the professionalism of the agricultural scientist, now that the pressure is on to mobilize smallholders and their productive resources for (global) food security and for reducing persistent rural poverty. Significant new thinking about pathways is emerging and it is useful to present some of this, even if it is not cut-and-dried. This new thinking focuses on innovation, not as the end-of-pipe outcome of development and transfer (or ‘delivery’) of results of research to ‘ultimate users’, but as a process of technical and institutional change at farm and higher system levels that impacts on productivity, sustainability and poverty reduction.

This paper will review technology supply push; farmer-driven innovation; market-propelled or induced innovation based on the agricultural treadmill; participatory technology development; and innovation systems. The pathways reviewed all have their merits; the paper will assess them from the perspective of improving smallholder productivity and livelihoods.

This paper concludes that many agricultural scientists have not developed their thinking about how the fruits of their work can help make the world a better place. This is a flaw in their professionalism. Curriculum development, training, promotion criteria, standards used in refereeing journal articles and research funding could benefit from taking on board understanding of pathways of science-for-impact.  相似文献

With the sustainable development goals has come a renewed global interest in ending hunger and achieving food security, while preventing natural resource degradation. Despite this renewed interest and increased commitments to invest in agricultural development, there is an outstanding debate over the technological trajectories to sustainability. The debate centres on sustainable agricultural intensification (SAI) and agroecological intensification (AEI) pathways to agricultural sustainability. Using a systematic literature review approach, this study examines the debate over AEI and SAI. This study employs a theoretical framework based on the economic, social, and ecological dimensions of sustainable agriculture within a policy and institutional space. Based on the sustainability dimensions, a discourse analytical technique is applied to unravel the debate. The results reveal differences in actor composition in the SAI and AEI pathways. Both pathways aim to promote food security with optimal and sustainable use of inputs; however, the actors differ on discourse relating to the concept of farming, the role of genetic engineering, the scale of operation, land use and soil health. Resolving these differences requires a blended sustainability approach that moves beyond the current AEI and SAI debate by acknowledging the tradeoffs and synergies of the socio-economic and ecological dimensions.  相似文献

Agrobiodiversity has been decreasing substantially in Europe. Social scientific research in this area has paid limited attention to how citizens value agrobiodiversity and its decline, and how these valuations can be influenced. We explore the influence of different arguments for enhancing agro-biodiversity, delivered via short movies, on attitudes and behaviour of students, environmental professionals and people interested in nature conservation in the Netherlands. We conclude that information provision does not influence attitudes. However, it does influence values assigned to agrobiodiversity, but not always in the ways we hypothesized. Information about the intrinsic value of agrobiodiversity has the most effects on values assigned to agrobiodiversity. Among students, women and people with a low emotional attachment with agricultural landscapes (‘place identity’ and ‘place dependence’), emphasizing the instrumental value of agrobiodiversity has a counter-intuitive effect. It does not influence the importance of this value but instead reinforces the intrinsic value they assign to agrobiodiversity. The latter finding is at odds with the instrumental biodiversity discourse in science and policy, which, under headings such as ecosystem services and natural capital, aims to mobilize support for nature conservation by emphasizing its instrumental, functional and economic values. Emphasizing the intrinsic value of agrobiodiversity seems more effective.  相似文献

Although agri-environmental policies have been launched by the European Union to mitigate environmental pollution and sustain agricultural development, there is not much understanding of how to manage the asymmetries between the objectives and the effectiveness of the implementation of the policies on local scale. The nitrate directive (ND) is an emblematic case in this context. This research focused on the role of ‘hybrid knowledge’ (scientific and local) and the process of knowledge integration in understanding the nitrate problem as an agri-environmental issue emerging from a complex set of biophysical and social factors. We conducted an integrated analysis of a case study on nitrate pollution in an intensive dairy district under Mediterranean conditions. A participatory action research approach was applied to elicit stakeholders’ knowledge and perspectives and to create new learning spaces among farmers, researchers and policy makers at case study scale. We explored the effectiveness of social learning triggered due to participatory field experiments, by bringing together stakeholders to generate new ‘hybrid knowledge’ for agri-environmental sustainability. The dramatic shift from the initial defensive position of farmers to an agreement on concerted actions proved that the integration between local and scientific knowledge may contribute to an increase in the effectiveness of the ND.  相似文献

An ongoing academic debate examines the implications of ‘developmental patrimonialism’ for African citizens. Rwanda is a key case study in this debate, with proponents of developmental patrimonialism and ‘party capitalism’ arguing that companies owned by the ruling party or the military play positive roles in economic development. This debate often focuses on macro‐level, elite politics. This paper instead uses a Foucauldian lens to examine the micro‐level politics of pyrethrum production in Rwanda, which is managed by a military‐owned company. The company utilizes incentive‐based governmental strategies, in line with state discourses, in addition to punitive, disciplinary regimes. The paper demonstrates that state agricultural strategies depend on multiple factors, including multi‐scale political tensions between the ruling party's desire for control and its discourse of ‘entrepreneurship’.  相似文献

The Red de Semillas Libres (Network of Free Seeds) in Colombia contests the expansion of, and dominant narratives on, agricultural biotechnology and intellectual property rights (IPRs) protections on seed – or what has been called ‘biohegemony’. We argue that despite its challenges, the Network contests ‘biohegemony’ through lawsuits, supporting ‘seed sovereignty’, and reframing the often taken‐for‐granted discourse on local seed varieties as raw material and a resource to be ‘discovered’, ‘invented’ and commodified by industry and Western‐based technoscience. Based on ethnographic research, we extend the concept of biohegemony to include struggle and contestation by examining how the Network pursues seed sovereignty.  相似文献

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies. In this paper, we share learning from efforts to mainstream such an approach through a large, multi-partner CGIAR research program working in aquatic agricultural systems. We reflect on four years of implementing research in development (RinD), the program’s approach to the new professionalism. We highlight successes and challenges and describe the key characteristics that define the approach. We conclude it is possible to build a program on a broader approach that embraces multidisciplinarity and engages with stakeholders in social-ecological systems. Our experience also suggests caution is required to ensure there is the time, space and appropriate evaluation methodologies in place to appreciate outcomes different to those to which conventional agricultural research aspires.  相似文献

This paper explores the relations between agricultural modernization and sustainable agriculture. The point of departure is the observable decrease in the sustainability and social–ecological resilience of agricultural and food systems. We ask where, precisely, the notions of agricultural modernization and agricultural sustainability contradict each other. In more concrete terms we ask what forms of modernization makes agriculture more (or less) sustainable. Our literature review shows that while the term ‘sustainable agriculture’, has been extensively debated, the term ‘agricultural modernization’, while carrying a positive and forward-looking connotation, remains poorly defined. To address this gap, we draw on evidence from real-life cases in fourteen countries in an attempt to interpret how the two concepts are perceived in very different contexts. These case studies show that different understandings of modern and sustainable agriculture coexist and that agricultural development follows diverse pathways. We conclude that the growing demands for an agricultural and food system that is more resilient, equitable and inclusive can be met by providing more support for the many divergent trajectories of agricultural modernization that practitioners are actually pursuing: trajectories that are often more attuned to the imperatives of ecology and to changing socio–economic preferences than the classical modernization trajectory.  相似文献

This paper uses the example of Spanish polytunnels to demonstrate how the deployment of ‘neo-productivist’ agricultural technologies to meet the demands of food security and sustainability within a globalised food chain is likely to precipitate greater countryside conflict. Field-scale ‘Spanish polytunnels’ for strawberry growing have become a new feature of the British agricultural landscape. This has been driven primarily by supermarkets searching for high quality and quantity supplies of soft fruit. With production becoming industrialised, conflict has ensued in some rural communities where polytunnels have appeared. Interviews with prominent strawberry growers and protestors against polytunnels illuminate a vociferous and embittered wrangle. Within it, land use planners are labelled as ‘strawberry fools’ by both sides for failing, until recently, to provide decisive regulation to prevent conflict and effect its resolution. The paper concludes by drawing attention to the future characteristics of conflicts precipitated as new agricultural technologies are implemented rapidly, impact unevenly and are received acrimoniously.  相似文献

Despite several environmental and economic benefits of crop rotation, the adoption of this agricultural practice is relatively low. Understanding the reasons for low adoption is important from a sustainability policy perspective. This study explores the motivation, challenges, and sources of information of agricultural producers who participate in crop rotation practices in South Dakota, North Dakota, and Nebraska. The findings of a mail survey of 672 producers in these three states show that producers are familiar with the crop rotation practice. Economic profitability is found to drive motivation for crop rotation adoption. The results of a binary logistic regression model show that a producer who perceives that crop rotation is beneficial to farm profitability is 1.83 times more likely to adopt it than the producer who does not believe in its profitability to the farm. The lack of time or resources is the primary barrier to the adoption of crop rotation practice. This study provides additional evidence in support of the importance of farm profitability for the adoption of the practice of crop rotation. Understanding the rationale and addressing the challenges faced by agricultural producers would be useful in planning and policy making of sustainable agriculture.  相似文献

Sustainable agricultural development is presented as a diverse and dynamic process through which it copes with agro-ecological and socio-economic diversity at field level and with ever-changing needs and opportunities of (smallholder) farmers. In support, agricultural research—aimed at locally appropriate and environmentally friendly technologies—should contribute to bridging the currently increasing gaps between scientific theories and government agricultural policies as opposed to the practical field realities that farmers are facing.

These gaps are best illustrated by—what in the West is often presumed to be—a stagnant African agricultural (in reality it is not!) in spite of many ambitious policies and projects by national governments and international donors for several decades. Disappointing adoption rates by resource-poor smallholders of the proposed ‘modern’ agricultural technologies have often been blamed. However, the actual local systems are primarily based on ‘ecological’ and ‘organic’ concepts. Localised intensification through recycling of organic by-products is an integral part of such systems. Consequently, these systems are uniquely adapted to the diverse framer needs resulting from widespread variations in soil, climate and socio-economic conditions. By contrast most international R&D support for the African agricultural sector is aimed implicitly at creating a modern conventional system of farming based on external inputs and along a Western industrial model.

To cope with diverse and complex, location specific problems inherent in development, sustainability and poverty alleviation, requires strong national research and development (R&D) institutions that adopt comprehensive, people-centred approaches as opposed to the technocratic nature of most formal international development assistance. The development debate therefore should be turned around. The ‘existing’ smallholder farming systems and their needs should be a point of departure, while the various development initiatives and policies should be handled by including the related institutional aspects.  相似文献

The study uses a nationally representative dataset of smallholder farmers in Zambia to determine the effect of agricultural productivity on households’ participation in charcoal production. An instrumental variable probit approach is applied to account for the endogeneity of agricultural productivity in household's charcoal participation decision. We find a negative and significant effect of agricultural productivity on household's likelihood of participation in charcoal production. Results also show that higher education, income, asset value, and participation in off-farm employment opportunities reduce the likelihood of participation in charcoal production. Therefore, interventions seeking to reduce charcoal production in rural Zambia could benefit from improving smallholder agricultural productivity, incomes, asset base, and off-farm employment creation. However, interventions need not lose sight of other important macro-level factors.  相似文献

Agricultural sustainability practices make the best use of both nature's resources and available technology, and generally avoid those land use practices that lead to greater environmental stress. There are examples in some agro-ecosystems, however, where stress is vital to food quality and productivity. In the case of grape production, a limited amount of environmental stress actually leads to an increase in fruit quality, and with wine grapes, to improved wine quality. But when the stress exceeds an acceptable threshold, vine vigour declines and production and quality may be compromised. Using our experiences with environmental stress in grapes grown in the landscapes of Central and Eastern Washington, USA, we question how agricultural sustainability should consider environmental stress, and at what point management interventions contribute or detract from a sustainable system. Framed by the two French land-related terms ‘appellation’ and ‘terroir’, we discuss agricultural sustainability for grape cultivation in an arid climate.  相似文献

The analysis of energy efficiency of agroecosystems from a sociometabolic perspective is a useful way to assess the sustainability of farm systems. In this paper we examine the transition of a Mediterranean agroecosystem from an organic farm system in the mid nineteenth century to an industrialized one at the end of the twentieth century by means of the technologies and ideology of the Green Revolution. Given that many of the world’s agricultural systems have experienced, or are currently experiencing this transformation, our results are relevant for building more sustainable agricultural systems in future. Our results highlight the relevance of livestock density, and the flows of biomass reused and unharvested biomass as key elements affecting the sustainability of the agroecosystem not only from a socioeconomic perspective, but also from an agroecological point of view. Additionally, from a biocultural perspective our investigation sustains the relevance of the study of traditional farm systems for the development of a sustainable agriculture.  相似文献

The growth of China's middle class is driving an expansion of interest in ‘green’ and sustainable food, food that is perceived to be healthy, safe and environmentally friendly. Self-consciously ‘sustainable’ agriculture is a new phenomenon in China, but it has emerged from, and builds upon, an agrarian history that is markedly different from that of the West. In this paper, we address the relationship between the Chinese middle class, an overwhelmingly urban group, and Chinese sustainable agriculture, a largely urban-oriented enterprise, from the perspective of our work in establishing and operating Beijing's first Community Supported Agriculture (CSA) farm. We discuss the farm's environmental and institutional sustainability, situating its development within the larger context of contemporary Chinese agriculture, and we examine the potential for future success with CSA models in China based on evidence from this case.  相似文献

Participatory approaches have emerged in developing countries as an integrated and holistic system approach for assessing the agro-ecosystem sustainability. The aim is to integrate and apply knowledge about natural and social aspects of agro-ecosystems, taking into account their long-term, uncertain and non-linear relationships. The purpose of the study described in this paper was to assess the sustainability of the agro-ecosystem of Abesard in Tehran Province. A participatory landscape/lifescape appraisal (PLLA) method was used within an agro-ecological framework to assess the farmers’ sense of agricultural sustainability based on different categories of sustainability (better-off, average and poor). Results indicated that a majority of farmers think of sustainability solely as an economic issue, followed by sustainability being a combination of ecological and social concerns. Regarding the indicators of sustainability, results revealed that for farmers in the poor group, resilience and stability were critical criteria, whereas for better-off farmers, stability, reliability and resilience were generally important. However, the average group of the farmers was placed between the two groups. Overall, it was concluded that the economic status of households has an influence on the sustainability of their agro-ecosystems and that improvement of their economic situation promotes agricultural sustainability. It could also be concluded that PLLA has the potential to integrate socio-economic (lifescape) and environmental (landscape) dimensions for analysing the sustainability of agro-ecosystems.  相似文献

The growing involvement of financial actors in food production has been one of the major recent transformations in the global agri‐food system. This ‘financialization’ of the agri‐food sector has been observed at various levels, from commodity speculation to direct investment in agricultural production, along with farmland itself. While there has been concerted effort to track new landownership and control associated with financial actors, especially in the Global South, there has been less impetus to examine the motives of financial actors' engagement in food production and the narratives upon which such engagement is based. This paper examines the way in which a productivist food (in)security discourse is employed by financial actors to legitimate their actions and to position themselves to win public approval. We analyse two cases of agri‐finance investors in the Australian context engaged in the discourse of food (in)security in relation to their agricultural investments – the Macquarie Group and Hassad Australia.  相似文献

The European political framework of the last decade aims to drive agriculture towards economic and environmental sustainability. Thus, European institutions have paid great attention to environmental impact assessment and to the definition of a complex indicator capable of restoring the multidimensional nature of environmental sustainability.In this work, a possible methodology for assessing the environmental sustainability of European national cropping systems by a synthetic indicator is provided. More specifically, the environmental impact of agriculture is assessed through a synthetic indicator, whose definition is based on a methodological improvement of the ecological footprint approach, which quantifies the balance between exploitation and availability of natural resources used in agriculture.The analysis shows how national cropping systems can contribute to Europe’s environmental impact through agriculture. To assess an eventual relationship between agriculture’s environmental performance and the ability to support more sustainable agriculture at the national level, the results are then compared with the subsidies for agro-environmental measures provided by the second pillar of the CAP. In addition, the synthetic indicator chosen for the study, giving the possibility of quantifying the dynamic of the environmental impact of agriculture between two different periods, permits the analysis of the possible causes that may have generated the observed changes.The implications of this approach should stimulate new reflections on the significance of the ecological relationships embodied into agricultural production and the environmental role of farmers.  相似文献
