Rice and Remittances: Crop Intensification Versus Labour Migration in Southern Laos

Despite being a low-income, agriculture-based country with a subsistence orientation, Laos is in the early stages of a major economic transformation whereby rural households have been experiencing rapid change in their farming and livelihood systems. Some households have begun to engage in semi-commercial farming while others have adopted labour-oriented or migration-oriented livelihood strategies. This paper explores how rural households in six villages in the lowlands of Champasak Province in southern Laos make a living. These villages vary in their access to irrigation and to markets. Nevertheless, in all villages, long-term migration of younger household members to neighbouring Thailand has come to play a large role in household livelihood strategies. In some cases this is necessary to meet the household’s consumption requirements; in most, it is part of a diversified strategy in which rice farming still plays a significant role, though still largely for subsistence. The paper examines some of the issues involved in attempting to promote intensive, market-oriented rice farming in a context of an emerging on-farm labour shortage combined with an increasing flow of remittances from migrant family members.     

Modelling as a tool to redesign livestock farming systems: a literature review

Livestock farming has recently come under close scrutiny, in response especially to environmental issues. Farmers are encouraged to redesign their livestock farming systems in depth to improve their sustainability. Assuming that modelling can be a relevant tool to address such systemic changes, we sought to answer the following question: ‘How can livestock farming systems be modelled to help farmers redesign their whole farming systems?’ To this end, we made a literature review of the models of livestock farming systems published from 2000 to mid-2009 (n = 79). We used an analysis grid based on three considerations: (i) system definition, (ii) the intended use of the model and (iii) the way in which farmers’ decision-making processes were represented and how agricultural experts and farmers were involved in the modelling processes. Consistent rationales in approaches to supporting changes in livestock farming were identified in three different groups of models, covering 83% of the whole set. These could be defined according to (i) the way in which farmers’ decisions were represented and (ii) the model's type of contribution to supporting changes. The first type gathered models that dynamically simulated the system according to different management options; the farmers’ decision-making processes are assumed to consist in choosing certain values for management factors. Such models allow long-term simulations and endorse different disciplinary viewpoints, but the farmers are weakly involved in their design. Models of the second type can indicate the best combination of farm activities under given constraints, provided the farmers’ objectives are profit maximisation. However, when used to support redesigning processes, they address neither how to implement the optimal solution nor its long-term consequences. Models of the third type enable users to dynamically simulate different options for the farming system, the management of which is assumed to be planned according to the farmers’ general objectives. Although more comprehensive, these models do not easily integrate different disciplinary viewpoints and different subsystems, which limits their usefulness as support tools for redesigning processes. Finally, we concluded about what specific requirements should be for modelling approaches if farmers were to be supported in redesigning their whole livestock farming systems using models.     

Real or Perceived: The Environmental Health Risks of Urban Sack Gardening in Kibera Slums of Nairobi, Kenya

Cities around the world are undergoing rapid urbanization, resulting in the growth of informal settlements or slums. These informal settlements lack basic services, including sanitation, and are associated with joblessness, low-income levels, and insecurity. Families living in such settlements may turn to a variety of strategies to improve their livelihoods and household food security, including urban agriculture. However, given the lack of formal sanitation services in most of these informal settlements, residents are frequently exposed to a number of environmental risks, including biological and chemical contaminants. In the Kibera slums of Nairobi, Kenya, households practice a form of urban agriculture called sack gardening, or vertical gardening, where plants such as kale and Swiss chard are planted into large sacks filled with soil. Given the nature of farming in slum environments, farmers and consumers of this produce in Kibera are potentially exposed to a variety of environmental contaminants due to the lack of formal sanitation systems. Our research demonstrates that perceived and actual environmental risks, in terms of contamination of food crops from sack gardening, are not the same. Farmers perceived exposure to biological contaminants to be the greatest risk to their food crops, but we found that heavy metal contamination was also significant risk. By demonstrating this disconnect between risk perception and actual risk, we wish to inform debates about how to appropriately promote urban agriculture in informal settlements, and more generally about the trade-offs created by farming in urban spaces.     

Macro-Micro Linkages and Structural Transformation: The Move from Full-Time to Part-Time Farming in a North Florida Agricultural Community

Recent research has focused on the effects of macro-level structural forces on local cultures and agricultural systems of production. While indigenous systems can be dramatically altered by these forces, local institutions can also try to adopt strategies for survival. In this article I focus on how the shade tobacco farmers of North Florida adapted to the market collapse of their major money crop. In order to remain in agriculture, farmers who were established in a full-time farming tradition had to consider strategies that included part-time farming and off-farm work. The part-time farmers are compared to those who have tried to remain full time to find how successful the adjustment process has been.     

Agricultural intensification in a Philippine frontier community: Impact on labor efficiency and farm diversity

There continues to be much debate in anthropology concerning the mechanism by which agricultural intensification takes place and its impact on labor efficiency, farm diversity, and quality of diet. A major reason for this lack of consensus is the paucity of data from case studies that focus on specific agricultural systems at the point of transition from extensive to intensive methods of cultivation. Research in a frontier community in the Philippines, where farmers are making the shift from swidden cultivation to small-scale irrigated rice production, indicates that intensification does not necessarily result in lower efficiency or a decline in dietary standards. Rather, farmers faced with growing population pressure and an unproductive short fallow swidden system have been motivated to adopt irrigation because it increases the efficiency of their labor while maintaining a reliable and diverse farming system.     

从事有机农业对农民福祉的影响

从事有机农业的农民福祉得到改善是有机农业发展的前提条件。采用Narayan等提出的福祉框架,回顾了有关有机农业行为和支持该行为的公共部门措施对农民福祉影响研究的文献,以厘清从事有机农业与农民福祉间的关系。研究表明,农民有机农业行为对其收入、健康、社会关系、安全和自由与选择等福祉要素产生影响。收入是农民福祉的首要构成要素,但农民有机农业行为究竟是增加还是降低其收入,需要考察具体情境中产量、成本和价格的综合作用,没有一致性结论。农民有机农业行为对其社会关系的影响具有双向性,但它对他们的健康、安全和选择机会的影响是积极的。公共部门通过财政支付、支持合作、建立与完善有机认证制度和采购绿色化等措施支持有机农业,有助于改善有机农民的福祉。其中,财政支付是最重要的支持措施。研究认为不同情境的农民有机农业行为对其福祉影响的综合评价、农民有机农业行为与其福祉间因果关系的检验和公共部门有机农业政策对有机农民福祉贡献的检验,是今后研究的重要选题。     

Evaluation of the sustainability of contrasted pig farming systems: breeding programmes

The sustainability of breeding activities in 15 pig farming systems in five European countries was evaluated. One conventional and two differentiated systems per country were studied. The Conventional systems were the standard systems in their countries. The differentiated systems were of three categories: Adapted Conventional with focus on animal welfare, meat quality or environment (five systems); Traditional with local breeds in small-scale production (three systems) and Organic (two systems). Data were collected with a questionnaire from nine breeding organisations providing animals and semen to the studied farming systems and from, on average, five farmers per farming system. The sustainability assessment of breeding activities was performed in four dimensions. The first dimension described whether the market for the product was well defined, and whether the breeding goal reflected the farming system and the farmers’ demands. The second dimension described recording and selection procedures, together with genetic change in traits that were important in the system. The third dimension described genetic variation, both within and between pig breeds. The fourth dimension described the management of the breeding organisation, including communication, transparency, and technical and human resources. The results show substantial differences in the sustainability of breeding activities, both between farming systems within the same category and between different categories of farming systems. The breeding activities are assessed to be more sustainable for conventional systems than for differentiated systems in three of the four dimensions. In most differentiated farming systems, breeding goals are not related to the system, as these systems use the same genetic material as conventional systems. The breeds used in Traditional farming systems are important for genetic biodiversity, but the small scale of these systems renders them vulnerable. It is hoped that, by reflecting on different aspects of sustainability, this study will encourage sustainable developments in pig production.     

Farmers’ Perspectives on Vital Soil-related Ecosystem Services in Intensive Swidden Farming Systems in the Peruvian Amazon

A growing dilemma is how to conserve Amazonian forest while allowing local people to secure their livelihoods. Small-scale swidden farming in Amazonia is entirely dependent on the continued provision of ecosystem services (ES) that generate the conditions for agriculture. This study identified soil-related ES needed for, and enhanced by, productive swidden systems from the farmer’s perspective. Workshops in six farming communities in northeastern Peru discussed various land uses, swidden systems that continue to be productive, and swidden systems on degraded land. The participating farmers noted changes in their production systems and described the ES (or lack thereof) in terms of soil quality, crop production quantity and quality, burning practices, forest regeneration, and farming skill. The central elements described in farmers’ own strategies for managing soil-related ES were fallow management for biomass production and crop diversity, factors identified as central to future ES management work in established agricultural areas in Amazonia.     

Agricultural Science in the Wild: A Social Network Analysis of Farmer Knowledge Exchange

Responding to demands for transformed farming practices requires new forms of knowledge. Given their scale and complexity, agricultural problems can no longer be solved by linear transfers in which technology developed by specialists passes to farmers by way of extension intermediaries. Recent research on alternative approaches has focused on the innovation systems formed by interactions between heterogeneous actors. Rather than linear transfer, systems theory highlights network facilitation as a specialized function. This paper contributes to our understanding of such facilitation by investigating the networks in which farmers discuss science. We report findings based on the study of a pastoral farming experiment collaboratively undertaken by a group of 17 farmers and five scientists. Analysis of prior contact and alter sharing between the group’s members indicates strongly tied and decentralized networks. Farmer knowledge exchanges about the experiment have been investigated using a mix of quantitative and qualitative methods. Network surveys identified who the farmers contacted for knowledge before the study began and who they had talked to about the experiment by 18 months later. Open-ended interviews collected farmer statements about their most valuable contacts and these statements have been thematically analysed. The network analysis shows that farmers talked about the experiment with 192 people, most of whom were fellow farmers. Farmers with densely tied and occupationally homogeneous contacts grew their networks more than did farmers with contacts that are loosely tied and diverse. Thematic analysis reveals three general principles: farmers value knowledge delivered by persons rather than roles, privilege farming experience, and develop knowledge with empiricist rather than rationalist techniques. Taken together, these findings suggest that farmers deliberate about science in intensive and durable networks that have significant implications for theorizing agricultural innovation. The paper thus concludes by considering the findings’ significance for current efforts to rethink agricultural extension.     

Rethinking Irrigation Efficiency: Chain Irrigation in Northwestern Spain

In recent decades, approaches to evaluating irrigation efficiency have undergone a radical reevaluation. Classical models considered drainage water “lost” to irrigation by flowing out of the system. The recognition that drainage water can remain in the system and become available for use by downstream irrigators has forced the reassessment. Irrigation may be relatively inefficient at the irrigation system and field levels but quite efficient at the basin level. The implications for small-scale, gravity-flow canal systems managed by farmers, which constitute 85% of the world's irrigated area, are significant. These implications are explored in an historic and ethnographic analysis of the chain irrigation system of the Orbigo valley of northwestern Spain. This system of drainage and reuse helps to account for high and sustained agricultural productivity by farmers in the region over several centuries. The property rights institutions devised by farmers to manage this system are discussed and its internal organization compared with south Asian cascade irrigation.This material is based upon work supported by the National Science Foundation under Grant No. DBBS 9122134.

Pasture-based dairying: challenges and rewards for New Zealand producers

New Zealand dairying farm systems are principally pasture-based or seasonal supply. Features of these systems and their management are described, together with their advantages and limitations. The characteristics of reproductive management needed to attain satisfactory economic performance of these farm systems is discussed. The low-cost pasture-based seasonal system dictates that animals be bred over a very short period compared to many overseas countries and this is assisted in particular by the use of hormonal treatment for anoestrum. Oestrus synchrony is not widely used although uptake is increasing, particularly in large herds. The constraints imposed by the farming system represent a significant challenge to the application of embryo technologies as embryos must be recovered and transferred over the short period between calving and artificial insemination and farmers demand either a high pregnancy rate or a high value calf to compensate for the cost of the procedure and any delay in achieving a pregnancy.     

Changing Realities—Perspectives on Balinese Rice Cultivation

This paper discusses issues of agrarian change in south-central Bali. The proximity to urban areas, especially the tourist centers along the southern coast, provides many off-farm employment opportunities for small-scale farming households. Although rice farming continues, for many households it has become a side business. The flexible nature of rice farming in terms of labor input and available casual off-farm work allows farming households to allocate their available labor to a variety of on-farm and off-farm income generating activities. The subak which unites farmers in the irrigation and cultivation of the rice crop plays an important role in supporting this flexibility. Still, the future of rice farming and the organization behind it looks rather dim with a younger generation unwilling to work in the “mud” and little appreciation of the many benefits the subak provides not only to the farming but to the wider community.     

Effects of Socioeconomic Conditions on Multiple Uses of Swamp Forests in Central Brazil

Local communities in central Brazil harvest buriti palm (Mauritia flexuosa) fruit from swamp forests as well as using them for agriculture and cattle and pig farming. This study describes the intensity of forest use by buriti fruit harvesters and identifies how their socioeconomic conditions influence resource use. We visited 75 swamp forests where buriti fruits are harvested and interviewed the head of the nearest household. Agriculture was practiced in 72?% of forests and cattle farming in 52?%. For almost half (48?%) of households agriculture and buriti fruit harvest were the main sources income. Forests resources were equally important to all socioeconomic classes, even richer farmers. The intensity of fruit harvest did not differ between collective and private use regimes of forests. Market access was a limitation to fruit harvest intensity. The high intensity of swamp forest use suggests that their conservation will require change to current management practices.     

Making the best of both worlds: Can high-resolution agricultural administrative data support the assessment of High Nature Value farmlands across Europe?

Worldwide, the role of farmlands for biodiversity conservation and the delivery of multiple ecosystem services has been widely acknowledged. In the European Union (EU), societal demands to include environmental conservation concerns within the Common Agricultural Policy (CAP) have resulted in the recognition of the importance of maintaining High Nature Value farmlands (HNVf).HNVf constitute complex social-ecological systems, which owe their nature conservation value to the maintenance of specific, mostly low-intensity farming systems, supporting high levels of species and habitats dependent on agricultural practices. Even though HNVf assessment in space and time is essential to evaluate the effectiveness of Rural Development Programmes, the diversity of rural landscapes across EU, the scarcity of data on farming systems, and the lack of common methodological guidelines has hampered the implementation of HNVf mapping and monitoring across Europe. Thus, there is a pressing need to develop and test methodological approaches that may support HNVf assessment across the EU.The Integrated Administration and Control System (IACS) which is mandatory for all EU Member States constitutes a system for the management and control of CAP payments to farmers. Essentially, IACS comprises high-resolution, spatially explicit information on the type and intensity of agricultural land-use. Even though such data exhibits high thematic, spatial and temporal resolution, IACS has seldom been used, due to significant access restrictions. Here, the potential to use IACS data to support the assessment of HNVf was evaluated within the German Federal State of Lower Saxony by implementing a recently developed methodological framework. Sets of indicators known to be essential for identifying potential HNVf and underlying farming systems (expressing landscape structure and composition, farming systems, and crop diversity), were derived from IACS. Spatial patterns of indicators were analyzed at two different scales to delineate the potential distribution of HNVf across Lower Saxony.Results highlighted that most regions in Lower Saxony were characterized by intensive farming practices including high livestock density, high share of intensive crops and low density of linear elements. Only 3% of the Utilized Agricultural Area (UAA) of Lower Saxony potentially constituted HNVf, with the majority of HNVf coinciding with mosaics of arable and/or permanent crops and semi-natural features under less intensive farming practices. Semi-natural grasslands, partially under agri-environment scheme management contracts, covered roughly 1% of the UAA and were mostly intermingled with other farmland habitats in extensively managed agricultural landscapes.In the context of the EU-wide HNVf assessment, IACS constitutes an important source of data, characterized by a high spatial, thematic and temporal resolution of data collected annually. Whilst having the potential for use in HNVf assessment, some challenges remain, especially due to significant access restrictions. Nevertheless, IACS constitutes a powerful tool to evaluate the extent and condition of HNVf across the EU countryside. Making use of IACS data in such a way could provide a stepping-stone towards achieving a more effective balance between the management and control of CAP support payments and the growing societal demands related to the maintenance and enhancement of farmland biodiversity and ecosystem services.     

Securing Access to Seed: Social Relations and Sorghum Seed Exchange in Eastern Ethiopia

Access to seed is crucial for farming, though few studies investigate household-level access in the informal ‘farmer seed systems’ which still supply most seed in poor countries. This paper uses empirical data of seed exchange practices for sorghum in eastern Ethiopia to analyze how social relationships influence access to off-farm seed for a major crop. Seed shortfalls are common, and farmer–farmer exchange is important for providing locally-adapted seed to fill this gap, but access varies considerably among households, also affecting quantities supplied and terms of exchange. Preferred sources for off-farm seed (neighbors, government, market) also vary among farmers, reflecting agroecology and asset-ownership, but also differing access to these sources. Social network theories highlight the importance of reciprocal ties, and the cultural norms underpinning them, in accessing seed. These cultural norms are contested, with some claiming that commercial transactions are increasingly common. Implications for interventions supporting farmer seed systems, particularly emergency seed aid, are discussed in relation to the socially-mediated nature of seed access.

Diffusing Risk and Building Resilience through Innovation: Reciprocal Exchange Relationships,Livelihood Vulnerability and Food Security amongst Smallholder Farmers in Papua New Guinea

This paper examines how oil palm migrant farmers in Papua New Guinea are responding to shortages of land for food gardening. Despite rapid population growth and planting nearly all of their land to oil palm, virtually all families continue to grow sufficient food for their families. The paper outlines the diverse range of adaptive strategies that households have employed to maintain food security, involving both intensification and innovation in farming systems. While gains from intensification have been significant and built resilience, they have been incremental, whereas innovation has been transformative and led to large gains in resilience. The adoption of more flexible land access arrangements on state leasehold land that ‘revive’ and adapt indigenous systems of land sharing and exchange that operated through kinship networks on customary land are innovative; they have increased the supply of land for food gardening thereby reducing risk for individual households and the broader smallholder community. The paper highlights the value of understanding farmer-driven innovations and the role of indigenous institutions and cultural values in sustaining and enhancing household food security.     

Evaluation of farmers' attitude and perception toward production risk: Lessons from Khyber Pakhtunkhwa Province,Pakistan

The variations in farming risk are classified into three key categories: market liberalization, natural disasters such as floods or drought, and climate change. This study aims at filling the existing research gap by the assessment of risk attitude and risk perceptions toward various types of risks. Primary data of 600 respondents were collected through a structured questionnaire in four flood-prone districts namely Peshawar, Mardan, Charsadda, and Nowshera of Khyber Pakhtunkhwa (KP) province of Pakistan. Equally Likely Certainty Equivalent and risk matrix techniques were utilized in determining the risk attitude and risk perceptions among the farmers. A probit regression model was used to analyze the relationships among dependent and independent variables. Findings of the study show that majority of the farmers were risk-averse, and floods, high input prices, crop diseases, and excessive precipitation were the main risks perceived by the farmers. Results of the probit regression model indicated that age, education level, farm location, off-farm income, and access to market information were the main factors that affect the farmers' risk attitude and perceptions. The research offers essential findings that can be used by policy-makers in the farming sector and researchers to understand risk attitude and perceptions of farmers empirically.     

Climate Change and Apple Farming in Indian Himalayas: A Study of Local Perceptions and Responses

Apple farming is an important activity and profession of farmer communities in the Himalayan states of India. At present, the traditional apple farming is under stress due to changes in climate. The present study was undertaken in an Indian Himalayan state, Himachal Pradesh, with the major aim of studying perceptions of farmers on the effects of climate change on apple farming along the altitudinal gradient. Through questionnaire survey, the perceptions of farmers were recorded at low hills (<2500 m), mid-hills (2500–3000 m), and upper hills (>3000 m). At all elevation range the majority of farmers reported that there was increase in atmospheric temperature, and hence at low hills 72% farmers believed that this increase in temperature was responsible for decline in fruit size and so that the quality. Thirty five percent farmers at high hills and 30% at mid hills perceived frost as a major cause for damaging apple farming whereas at low hills 24% farmers perceived hailstorm as the major deterrent for apple farming. The majority of farmers, along the altitude (92% at high hills, 79% at mid hills and 83% at low hills), reported decrease in snowfall. The majority of farmers at low altitude and mid altitude reported decline in apple farming whereas 71% farmers at high hill areas refused decline in apple farming. About 73–83% farmers admitted delay in apple’s harvesting period. At mid hills apple scab and at low hills pest attack on apple crops are considered as the indicators of climate change. The change in land use practices was attributed to climate change and in many areas the land under apple farming was replaced for production of coarse grains, seasonal vegetables and other horticulture species. Scientific investigation claiming changes in Indian Himalayan climate corroborates perceptions of farmers, as examined during the present study.     

Developing and quantifying indicators of organic farming using analytic hierarchy process

Although regulations and criteria relating to organic farming are clearly defined by the relevant agencies, especially by IFOAM, some have been overshadowed by attention to others and have lost their significance over time. The aim of this study was to develop and quantify organic farming indicators to determine the relative importance of each. The desired indicators were collected during a literature review of scientific resources about the principles of organic farming. These indices were classified into four categories and their weights were determined through interviews with experts on organic agriculture, including university professors, agroecology students, Ministry of Agriculture experts, organic farming inspectors and organic farmers. The analytic hierarchy process (AHP) was used for this purpose. The results showed that pest and disease management, yield, soil nutrient management, water consumption rate, chemical fertilizer consumption rate and the use of transgenic materials having weights of 0.16, 0.098, 0.096, 0.08, 0.071 and 0.059, respectively, and are the most important indicators for development and assessment of organic farming. In this as well as similar studies, the weight of indicators associated with consumption of chemical fertilizers and pesticides were relatively high. This indicates the importance of rules related to the use of chemicals in organic farming; however, each index has a certain weight and none can be overlooked. All indicators should be considered as an inseparable set and all should be used in the development of organic farming. The results of this study can be useful for both inspection bodies and organic farmers. Farmers can reduce the risks associated with transitioning to organic farming and minimize the probability of failure by monitoring these indicators in their fields.     

Pesticide handling practices,health risks,and determinants of safety behavior among Iranian apple farmers

Common safety practices in pesticide use were assessed among apple farmers in Ardabil Province, Iran. With reference to the place of storing pesticides, most farmers (60%) stated that they store the pesticides in stalls and warehouses, while 8.5% stated that they store the pesticides in their houses. The majority of the farmers (71.5%) stated that they prepare the pesticide sprays in the orchards or next to irrigation wells. Almost one out of three farmers (32.8 %) reported that they dump the empty containers in the orchard fields and almost an equal proportion (30.2%) reported that they usually bury the empty containers. Irritating (burning) eyes and blurred vision were symptoms that the majority of respondents had experienced. Most farmers used trousers, long-sleeved blouses/shirts, and gloves when spraying, but coveralls and goggles were rarely used. Age and farming experience negatively affected PPE use and safety behavior, namely old and experienced farmers did not follow safety rules. On the contrary, education, information about pesticides, and farming as the main profession promoted safety behavior. Overall, significant levels of exposure among farmers can be concluded due to pesticide use. The extension services should aim human safety in relation to pesticide use in agriculture.
