Organic conversion subsidies used in Europe are less likely to be politically acceptable in the United States, where organic agriculture development is market‐driven. Persistent barriers to conversion in the United States include limited availability of and access to production and market information, training in management systems and cost of conversion‐related investments. By determining whether these factors affect the requirement of a subsidy to convert, we can suggest whether U.S. policy makers need to provide subsidies to encourage conversion and identify policy variables consistent with market‐based approaches that could stimulate conversion. A utility difference model is used with Swedish data to analyze factors that determine whether a subsidy is required to motivate organic conversion. The results show that farmers requiring subsidies manage larger less‐diversified farms and are more concerned with organic inspection, quality, and adequacy of technical advice. Access to more market outlets and information sources substitutes for payment level in the farmer's utility function, indicating that services rather than subsidies may be used to encourage organic agriculture. To the extent that conditions are similar in the U.S. organic sector, market‐based programs such as cost‐sharing for conversion and market access improvement should stimulate growth of this industry.  相似文献

This paper reports results from a study of resource degradation and conservation behavior of peasant households in a degraded part of the Ethiopian highlands. Peasant households' choice of conservation technologies is modeled as a two-stage process: recognition of the erosion problem, and adoption and level of use of control practices. An ordinal logit model is used to explain parcel-level perception of the threat of the erosion problem and the extent of use of conservation practices. Results show the importance of perception of the threat of soil erosion, household, land and farm characteristics; perception of technology-specific attributes, and land quality differentials in shaping conservation decisions of peasants. Furthermore, where poverty is widespread and appropriate support policies are lacking, results indicate that population pressure per se is unable to encourage sustainable land use. The challenge of breaking the poverty-environment trap and initiating sustainable intensification thus require policy incentives and technologies that confer short-term benefits to the poor while conserving the resource base.  相似文献

Participatory approaches to agricultural technology development have not yet fully lived up to their promise to incorporate farmer knowledge. This paper introduces a social networks approach (SNA) to improve participatory research processes for co-innovation. Drawing upon findings from a collaborative project developing conservation agricultural production systems for smallholders in western Kenya and eastern Uganda, the paper explores farmer support networks to improve participation in technological innovation and development. Key research themes include: identifying farmers’ agricultural production networks; the local articulation of agricultural production networks and mindsets; using networks to facilitate meaningful participation in technology development; and disadvantages and advantages of using a social network approach. The introduction of SNA improved participatory research by building external and internal legitimacy for determining who participates, discouraging participatory attrition, and providing a meaningful forum for participation of all stakeholders. As a result, the introduction of SNA is demonstrated to show strong promise for improving processes of participatory technology development in agriculture.  相似文献

Agricultural policies in sub-Saharan Africa have paid insufficient attention to sustainable intensification. In Uganda, agricultural productivity has stagnated with aggregate increases in crop production being attributed to expansion of cultivated land area. To enhance sustainable crop intensification, the Ugandan Government collaborated with stakeholders to develop agricultural policies using an evidence-based approach. Previously, evidence-based decision-making tended to focus on the evidence base rather than evidence and its interactions within the broader policy context. We identify opportunities and pitfalls to strengthen science engagement in agricultural policy design by analysing the types of evidence required, and how it was shared and used during policy development. Qualitative tools captured stakeholders' perspectives of agricultural policies and their status in the policy cycle. Subsequent multi-level studies identified crop growth constraints and quantified yield gaps which were used to compute the economic analyses of policy options that subsequently contributed to sub-national program planning. The study identified a need to generate relevant evidence within a short time 'window' to influence policy design, power influence by different stakeholders and quality of stakeholder interaction. Opportunities for evidence integration surfaced at random phases of policy development due to researchers’ ’embededness’ within co-management and coordination structures.  相似文献
