Farmers’ decisions to conserve natural resources generally and soil and water particularly are largely determined by their knowledge of the problems and perceived benefits of conservation. In Ethiopia, however, farmer perceptions of erosion problems and farmer conservation practices have received little analysis or use in conservation planning. This research examines farmers’ views of erosion problems and their conservation knowledge and practices in the Beressa watershed in the central highlands of Ethiopia. Data were obtained from a survey of 147 farm households managing 713 fields during the 2002/2003 cropping season. In-depth interviews and group discussions were also held with the farmers to obtain additional information. The results show that 72% of the farmers reported erosion problems, and they recognized that conservation was necessary. However, they considered erosion to be severe mostly when visible signs – rills and gullies – appeared on their fields. The majority of the farmers believe that erosion could be halted, and they use a range of practices for erosion control and fertility improvement. These include contour plowing (83%), drainage ditches (82%), and stone terraces/bunds (73%). Nevertheless, despite decades of conservation intervention in the area, it appears that most farmers have developed negative attitudes towards externally recommended measures. The research concludes that under the conditions present in the Ethiopian central highlands, soil and water conservation interventions should consider farmers’ conservation knowledge and practices to improve acceptance and adoption of the recommendations.

The conservation of rice plant genetic diversity is particularly important for resource-poor farmers in economically marginal areas of the Philippines. This paper discusses the state of rice plant genetic diversity in the Philippines and the reasons behind the decrease in diversity witnessed over the last 30 years. A case study describes the in situ management of rice plant genetic diversity by resource-poor farmers from the Philippine island of Bohol, throughout the traditional, green revolution, and post-green revolution periods. This analysis demonstrates that farmers tend to favor genetically heterogeneous varieties that adapt to varied environments. The case study also reviews an NGO-sponsored agricultural biodiversity project that demonstrates that rice plant genetic diversity can be increased by empowering farmers – providing them with access to varieties, knowledge of varietal trials, varietal selection, and varietal breeding, as well as increasing the linkages they have with other farmers and institutions. David Carpenter is a PhD candidate in the School of Resources, Environment and Society at the Australian National University. His current research focuses on organic rice farming, social capital, and agricultural change in the Philippines. He recently published an article in Agriculture and Human Values 20(2) on the transition from high input agriculture to organic agriculture by resource-poor farmers from the Philippine Island of Bohol.  相似文献

Although many governments have privatized their agricultural extension services, there is widespread agreement that the public sector still needs to play a role in the “agricultural knowledge market” in order to prevent market failure and other undesirable phenomena. However, appropriate mechanisms for intervention in the agricultural knowledge market are still in their infancy. This article discusses the case of the Nutrient Management Support Service (NMSS), a government-funded support service in The Netherlands designed to optimize the fit between the demand and supply of “agricultural knowledge products” that reduce nutrient emissions into the environment. The activities of the support service were four-fold: (1) distributing vouchers to farmers, (2) establishing mechanisms for quality control, (3) facilitating the articulation of end-users’ needs, and (4) improving market transparency. We analyze the extent to which the NMSS has succeeded in supporting a demand-driven knowledge market for nutrient management issues. We question some of the conceptual and practical assumptions underlying this style of intervention. In addition, we argue that the notion of demand requires considerable refinement before it can be useful for guiding state involvement in demand-driven extension. Laurens Klerkx holds a MSc in Tropical Land Use from Wageningen University. He is currently working on his PhD. His research focuses on how needs are articulated in demand-driven agricultural innovation processes and how newly emerging institutions such as knowledge brokers, knowledge networks, and innovation facilitators support this demand-driven agricultural innovation. Karin de Grip studied Tropical Agriculture (BSc) and, after working for 3 years in Indonesia in development co-operation, joined the MSc program in Management of Agri-ecological Knowledge and Social Change at Wageningen University. Her specific foci and interests include interactive knowledge development processes, learning processes, knowledge exchange and innovation networks, enforcement of knowledge markets, and demand-driven extension. Cees Leeuwis is professor of Communication and Innovation Studies at Wageningen University. He holds a MSc in Rural Sociology and a PhD in Communication and Innovation Studies. His research focuses on (a) the role of new interactive and cross-disciplinary approaches in bringing about coherent innovations, (b) the analysis of social learning and conflict management in networks, and (c) the way in which the privatization of research and extension institutions affects public sphere innovation processes.  相似文献

This article analyzes learning in context through the prism of a sustainable dairy-farming project. The research was performed within a nutrient management project that involved the participation of farmers and scientists. Differences between heterogeneous forms of farmers knowledge and scientific knowledge were discursively constructed during conflict and subsequent alignment over the validity and relevance of knowledge. Both conflict and alignment appeared to be essential for learning in context. Conflict spurred learning when disagreeing groups of actors developed their knowledge in order to strengthen their arguments. Conflict caused self-referentiality when the actors no longer listened to each other. This inhibited self-reflection, thus blocking ongoing learning. Nevertheless, after a period of alignment, scientific models and knowledge of farmers were reevaluated and recontextualized. Through determining how to use scientific models and farmers knowledge for further learning, aimed at a shared goal, the participating actors also learned how to learn.Jasper Eshuis is a PhD candidate in the Department of Communication Management at Wageningen University, The Netherlands.

Sweetpotato-pig production is an important system that generates income, utilizes unmarketable crops, and provides manure for soil fertility maintenance. This system is widely practiced from Asia to Africa, with many local variations. Within this system, pigs are generally fed a low nutrient-dense diet, yielding low growth rates and low economic efficiency. Our project in Vietnam went through a process of situation analysis, participatory technology development (PTD), and scaling up over a seven-year period to improve sweetpotato-pig production and to disseminate developed technologies. The situation analysis included a series of pig production assessments in several provinces in northern and southern Vietnam, and pig supply-market chain identification was conducted in 13 provinces. The analysis of these studies informed the project of the following: (1) appropriate locations for our activities; (2) seasonal available feedstuff and farmers feeding practices; (3) market fluctuation and requirements; and (4) feeding and management improvement needs based on which the subsequent phase of PTD was designed. The PTD involved a limited number of farmers participating in sweetpotato varietal selection, sweetpotato root and vine silage processing, seasonal feeding combination, and pig feeding with balanced crop-feed diet and silage. Six years of multi-location and multi-season sweetpotato selection resulted in a few promising varieties that yielded up to 75% more dry matter and have since been formally released. The most significant results of silage processing and feeding trials include improved growth, higher feeding efficiency, increased year-round local feedstuff, and considerable labor reduction from eliminated cooking and vine cutting. Once these technologies were developed, a farmer-to-farmer training model was designed for scaling up the adoption and impact. Farmer trainers from seven communes in seven provinces received training in these technologies. In turn, they undertook the responsibility of training other farmers on sweetpotato selection, processing, and feeding. An impact study was also administered to monitor and evaluate (M&E) the dissemination process and to document the impact of the new technologies and farmer-to-farmer training model on pig growth and farmer income generation. The results showed that both participating and non-participating farmers have taken up the technologies, although the former demonstrates higher rates of adoption than the latter. The participants also generated more income and saved more labor from the adoption of the technologies. While the scaling up and M&E activities are on-going, the project has since broadened from a sweetpotato-pig system perspective to a pig-cropfeed system perspective based on farmers needs. It has included other crop feeds such as cassava and peanut stems in the research portfolio. New technologies based on on-going PTD will continuously be incorporated into the future training curriculum.Dai Peters is currently a senior scientist with the International Center for Tropical Agriculture (CIAT) based in Hanoi, Vietnam.

This paper addresses the motivations behind farmers’ pesticide use in two regions of Bangladesh. The paper considers farmers’ knowledge of arthropods and their perceptions about pests and pest damage, and identifies why many farmers do not use recommended pest management practices. We propose that using the novel approach of classifying farmers according to their motivations and constraints rather than observed pesticide use can improve training approaches and increase farmers’ uptake and retention of more appropriate integrated pest management technologies.

The primary focus of agricultural research and extension in eastern Africa is technology generation and dissemination. Despite prior critiques of the shortcomings of this approach, the consequences of such activities continue to be measured through the number of technologies developed and introduced into the supply chain. At best, impact is assessed by the total numbers of adopters and by the household and system factors influencing adoption. While the diffusion research tradition has made substantive advances in recent decades, attention to what happens to technologies after adaptive, on-farm research trials continues to be limited in practice. While a host of newer approaches designed to correct for past shortcomings in diffusion research is now available, integrative methodologies that capitalize on the strengths of these different traditions are sorely needed. This article presents a more encompassing methodology for tracking the fate of technological interventions, illustrating the potential applications of findings for enhancing the positive impact of agricultural research and extension in the region.

Sustainable agriculture and ways to achieve it are important issues for agricultural policy. However, the concept of sustainability has yet to be made operational in many agricultural situations, and only a few studies so far have addressed the implementation process of sustainable agriculture. This paper provides an assessment of the Territorial Farming Contracts (TFC) – the French model for implementing sustainable agriculture – and aims to give some insights into the ways to facilitate the development of sustainable farming. Using a systems approach, the founding concept of the TFC model, an analysis has been made of the TFCs signed in the Midi-Pyrenees Region in south-western France. The results show that the first aspect of sustainability apparent in farmers’ projects referred to economic objectives. The environmental and social aspects were not foremost in the farming changes undertaken. In addition, the territorial dimension of the TFC was under-addressed. The majority of TFCs reveal a moderate or even low convergence with territorial priorities. These results are explained partly by the dominance of professional farming organizations in the implementation of TFC, and they imply that the organizational social dimensions of sustainability must not be neglected.

In 2004 a survey was conducted in the member states of the European Union designed to gain greater insight into the views on control strategies for foot and mouth disease, classical swine fever, and avian influenza with respect to the epidemiological, economic and social-ethical consequences of each of these animal diseases. This article presents the results of the social-ethical survey. A selection of stakeholders from each member state was asked to prioritize issues for the prevention and control of these diseases. A majority of stakeholders chose preventive measures as the preferred issue. An analysis was done to determine whether there were differences in views expressed by stakeholders from member states with a history of recent epidemics and ones without such a history, and whether there were regional differences. There were no differences between member states with or without a history of recent epidemics. There were indeed regional differences between the priority orders from Northern and Southern Europe on the one hand, and from Eastern Europe on the other. Nina E.

This study investigated poultry farmers’ perceptions, preferences, and use of commercially compounded and self-compounded feeds in the Oyo Area of Oyo State, Nigeria. Data were collected from 120 poultry farmers through a structured interview schedule. The study concluded that poultry farmers prefer and use self-compounded feeds (SCF) instead of commercially compounded feeds (CCF) because (a) self-compounded feeds are of better quality than commercially compounded feeds, (b) there are no quality control measures in the poultry feed industry in the Oyo Area, (c) commercially compounded feeds cost more than self-compounded feeds, and (d) farmers choose feed based on the perceived quality of the feed, their technical ability to produce feed by themselves, the cost of CCF, the storability of feed, and the cost and availability of transportation. Based on these findings, it is recommended that interested public and private agencies should organize annual extension workshops and training for poultry farmers in the study area on (a) feed formulation; (b) feed ingredient mixing and compounding; (c) selection of ingredients, mixtures, and additives; and (d) the establishment, operation, and maintenance of feed mills. Farmers should be encouraged to form feed mill cooperative societies. The performance of the Standards Organization of Nigeria (SON) should be monitored and evaluated to ensure its effective oversight of quality standards for agricultural products and inputs such as feeds and feed ingredients.

The goal of this paper is to show how culture – shared norms and values – is challenged and used to facilitate cooperative behavior within the context of farmer field schools (FFS) in central Luzon, Philippines. The success of the FFS is primarily associated with cultural norms that encourage experiential and collective learning and eventually lead to the adoption of integrated pest management (IPM) methods among the farmers. The study was conducted in central Luzon, the rice granary region of the Philippines, from 1992 to 1995 and again in 1999. Both qualitative and quantitative research methods were employed. Results indicate that a keen understanding of Filipino culture and values is essential if FFS is to be successful and if farmers are to successfully learn and practice IPM.

Village communities are not homogeneous entities but a combination of complex networks of social relationships. Many factors such as ethnicity, gender, socio-economic status, and power relations determine one’s access to information and resources. Development workers’ inadequate understanding of local social networks, norms, and power relations may further the interests of better-off farmers and marginalize the poor. This paper explores how social networks function as assets for individuals and households in the rural areas of developing countries and influence access to information and benefits from research and development. A case study of such networks in Phieng Lieng village, in the northern mountains of Vietnam, provides evidence for the need for the efficient delivery of extension services and research and development interventions at the micro level.

This paper reports on action research that evaluated local perceptions and knowledge of indigenous tree planting and management in the Romwe catchment, Chivi District, southern Zimbabwe. The species tested were the overexploited Afzelia quanzensis, important for timber and carvings of sculptures and utensils; Sclerocarya birrea, the marula tree used for wood, bark, and fruit; and Brachystegia glaucescens, the dominant miombo tree species, used for firewood, fiber, and fodder. Participants volunteered to plant and manage the test seeds, while a research team monitored their activities and results for 26 months. For Afzelia quanzensis, the germination rate was 81%, and 69% of the seedlings were still alive after one year. In the case of Sclerocarya birrea, the germination rate was 69%, and the one-year survival rate was 50%. For Brachystegia glaucescens, the germination rate was only 30%, and the survival rate was 31%. The main reasons for planting were to provide shade, to serve as a windbreak, and to conserve and gain individual control over dwindling natural resources, particularly Afzelia quanzensis. Women were generally more active and innovative than men. For instance, they searched for their own seeds or seedlings in the bush when there weren’t sufficient plants. Some participants tried out various indigenous methods of pest and disease control, water conservation, and moisture retention. Group feedback sessions and informal interactions provided the opportunity to share experiences. The participants learned that indigenous trees can be purposefully planted and were not simply a gift from God. Despite the droughts and political instability of recent years, a growing number of people became involved in tree planting during 2002–2003. As a result, there is now greater awareness among the local population of dwindling resources and their future potential.

While questions about the environmental sustainability of contemporary farming practices and the socioeconomic viability of rural communities are attracting increasing attention throughout the US, these two issues are rarely considered together. This paper explores the current and potential connections between these two aspects of sustainability, using data on community members’ and farmers’ views of agricultural issues in California’s Central Valley. These views were collected from a series of individual and group interviews with biologically oriented and conventional farmers as well as community stakeholders. Local marketing, farmland preservation, and perceptions of sustainable agriculture comprised the primary topics of discussion. The mixed results indicate that, while many farmers and community members have a strong interest in these topics, sustainable community development and the use of sustainable farming practices are seldom explicitly linked. On the other hand, many separate efforts around the Valley to increase local marketing and agritourism, improve public education about agriculture, and organize grassroots farmland preservation initiatives were documented. We conclude that linking these efforts more explicitly to sustainable agriculture and promoting more engagement between ecologically oriented farmers and their communities could engender more economic and political support for these farmers, helping them and their communities to achieve greater sustainability in the long run.

Immigrant farmers from Southeast Asia have brought knowledge of tropical fruit and vegetable production from their home countries to Homestead, Florida. They have developed a new style of farming, one that most closely resembles agricultural systems described as “homegardens.” Although biodiverse agricultural systems are generally thought to be commercially unviable, homegarden farmers successfully manage crop diversity as an economic strategy. By focusing on growing a mixture of specialty Southeast Asian herbs, fruits, and vegetables, the farmers have created their own economic niche and have shielded themselves from the competition of high-volume, single commodity producers. This paper shows that the Homestead homegardens constitute an alternative form of agriculture that is defined by their agroecological and socioeconomic attributes. It also shows that although the homegarden farms are a form of “alternative agriculture,” they do not operate outside of conventional, global systems of agricultural trade; rather the homegarden farms are embedded in global agriculture. The Homestead case problematizes the tendency to delineate between the global and local scales, and alternative and conventional sectors in agriculture today. This paper concludes that the emergence of the Homestead homegardens can only be understood by taking a place-based approach to studying the environment in which the homegardens are situated as well as identifying the large-scale influences on Miami-Dade County.

This study examines parents’ perspectives on their children working on their family dairy farms in Wisconsin. The objective of this focus group study is (1) to gain insights on why children work on their family farms, (2) to identify those benefits that parents perceive that they and their children gain from their children working on-farm, (3) to determine the concerns that parents have about their children working, (4) to identify ways to improve the safety of children on family farms, and (5) to understand how US agricultural policy impacts family decisions to use their children’s labor on their farms. The two focus groups reveal that fathers and mothers have different concerns and different perceptions regarding the benefits gained from having their children work on farms. The findings suggest that in response to US agricultural policy, parents are increasingly reliant upon their children’s labor. Children work the longest hours on economically stressed farms.

Integrated pest management (IPM) has been widely promoted in the developing world, but in many regions its adoption rates have been variable. Experience has shown that to ensure IPM adoption, the complexities of local agro-production systems and context-specific folk knowledge need to be appreciated. Our research explored the linkages between farmer knowledge, pest management decision making, and ecological attributes of subsistence maize agriculture. We report a case study from four rural communities in the highlands of southeast Honduras. Communities were typified by their agro-environments, IPM training history, and levels of infestation by a key maize pest, the fall armyworm (Spodoptera frugiperda Smith). Although variable, infestation levels generally did not justify pest management intervention. Consequently, crop losses from this pest were considered of low importance and most farmers proceeded in a rational fashion by refraining from action in their fields. Farmers attributed the low degree of pest infestation predominantly to abiotic causal factors (rainfall, temperature). The role of natural enemies in controlling this pest (i.e., biological control) was deemed of low importance by farmers; nevertheless, a broad array of such organisms was mentioned by farmers as operating in their maize crop. Farmers’ knowledge of natural enemies only partially matched scientific knowledge and was associated with the ecological features of their respective field settings. Local knowledge about natural enemies was mainly restricted to abundant and easily observable predatory species. Farmers who were knowledgeable about biological control were also familiar with a larger variety of pest management alternatives than uninformed farmers. Management options covered a wide range of curative techniques, including conservation biological control. Farmers who relied on insecticides to manage pest outbreaks knew less about biological control and pesticide alternatives. In contrast, farmers who received IPM training mentioned more types of natural enemies and were familiar with a broader range of alternative pest management tactics. Our research suggests that IPM training modifies local knowledge to better fit its environmental context. This paper provides insights in the environmental context of local agro-ecological knowledge and its linkage with pest management decision making. It also constitutes a basis for modifying IPM extension programs to deliver locality-specific technologies while strengthening the local knowledge base. Kris A. G.

Conversion to organic farming, along with its associated driving forces and barriers, has been explored intensively over the past decade, while studies on the distribution and impacts of local socio-cultural processes in relation to conversion to and diffusion of organic farming have been scarce. The concentration of organic farms in Denmark differs according to county and, moreover, there appears to be large within-county variation in the density of organic farms. The present study explores local aspects of conversion to organic farming and the factors that may help explain variation in density and concentration of organic farms within smaller areas. The study is based on nine qualitative interviews with organic farmers from two neighboring areas, referred to as “mainland” and “island,” respectively. Three farms were situated in the high-density area (mainland) and the remaining six in the low-density area (island). Furthermore, five advisors with connections to the area provided information with regard to their local experience and perceptions. Three main, and to some extent interacting, issues are discussed. The first is the price of land related to local scarcity of land, in the context of structural development and the effects of agricultural policies. The second is distance – both physical and social. Cooperation and exchange of experience among organic farmers was frequent on the mainland side, while isolation and lack of interaction was more common for the island farmers. Third, the role of the agricultural advisory service and the existence of champion farmers are important: pioneer farmers on the mainland have been supported by committed agricultural advisors, while lack of organic champion farmers and low priority granted to organic farming among agricultural advisors were found on the island. Marie-Louise Risgaard has an MSc within the field of organic agriculture. Her research interests are organic farming and rural development with the present occupation as innovative partner at a small-scale organic enterprise. In this capacity she is responsible for creating links between the organic enterprise, the gastronomic sector and organic markets, locally as well as nationally. Pia Frederiksen, PhD, is a geographer and senior scientist with research skills in rural development, sustainability, landscape analysis, and agri-environmental indicators. Pernille Kaltoft, PhD, is an environmental sociologist and senior scientist whose work focuses on organic farming and farmers’ perceptions. Dr. Kaltoft’s general research interests include values, perceptions, and views of nature related to agricultural and environmental issues.  相似文献

Although the potential of indigenous knowledge in sustainable natural resource management has been recognized, methods of gathering and utilizing it effectively are still being developed and tested. This paper focuses on various methods used in gathering knowledge on the use and management of tree fodder resources among the Maasai community of Kenya. The methods used were (1) a household survey to collect socio-economic data and identify key topics and informants for the subsequent knowledge elicitation phase; (2) semi-structured interviews using key informants to gather in-depth information; (3) tree inventory to collect quantitative data on the ecological status of trees and shrubs on rangelands; and (4) group consensus method to countercheck information elicited from key informants. Study results obtained show that the use of multiple methods in an appropriate sequence is an effective way of building upon the information elicited from each stage. It also facilitates the collection of different types of data and knowledge allowing a measure of triangulation, which can be used to confirm the validity and consistency of indigenous knowledge. Multiple methods also allow the collection of more knowledge than can be obtained if only one method is used. Therefore, it is recommended that future studies on indigenous knowledge systems use multiple methods that combine both individual and group interviews in order to obtain more complete and accurate information. Evelyne Kiptot, a research scientist with the Kenya Forestry Research Institute, is based at Muguga Regional Research Centre but is currently a PhD student in the Technology and Agrarian Development (TAD) chair group at Wageningen University in the Netherlands. Her current research activities focus on indigenous knowledge systems in pastoral areas, participatory approaches, and upscaling.  相似文献
