This paper considers genetically modified (GM) seed adoption decisions by farmers in a developing country under two alternative information regimes (with and without perfect information regarding production conditions) that allows the monopolist producer of GM seeds to either practice perfect discrimination or uniform pricing. Under each regime we analyze two scenarios: when the government can and cannot credibly commit to the announced form of welfare enhancing intervention in the domestic seed market.
The pursuit of sustainability in particular places and sectors often unravels at the edges. Efforts to tackle environmental problems in one place shift them somewhere else or are overwhelmed by external changes in drivers. Gains in energy efficiency of appliances used in houses are offset by greater total numbers or compensating changes in patterns of use. Analytical perspectives and practical initiatives, which treat production and consumption jointly, are needed to complement experiences and efforts with sector-, place-, product- and consumer-oriented approaches.
We examine the impact of ambiguous and contested land rights oninvestment and productivity in agriculture in Akwapim, Ghana. Weshow that individuals who hold powerful positions in a local politicalhierarchy have more secure tenure rights and that as a consequencethey invest more in land fertility and have substantially higher output.The intensity of investments on different plots cultivated by a givenindividual corresponds to that individual’s security of tenure overthose specific plots and, in turn, to the individual’s position in thepolitical hierarchy relevant to those specific plot
L’ouest du Rio Grande do Sul est dominé par la culture du soja, du riz et par l’élevage bovin. Dans la partie sableuse, le milieu est affecté par des phénomènes d’érosion produisant des modelés éoliens spectaculaires (arenização) rappelant dans l’imaginaire ceux des déserts. La production agricole est importante ce qui engendre des prélèvements d’eau pour l’irrigation du riz, mais aussi l’utilisation de pesticides pour l’ensemble des cultures. La gestion durable des ressources en eau et en sol de cette région nécessite la mise en place d’action de conservation.
This brief explains about a three-year research project (2006-09), conducted by the Center for International Forestry Research in the lower Mekong River countries (Cambodia, Laos and Vietnam). The best practices in design and implementation were identified through a broad review of the literature and an inventory of the multivariate techniques on a large set of variables. This research explored patterns among sites, project design, project activities and management.
Grown in Jamaica since the days of slavery, food yams are major staples in local diets and a significant non-traditional export crop. The cultivation system used today is the same as 300 years ago, with alleged unsustainable practices. A new cultivation system called minisett was introduced in 1985 but the adoption rate twenty four years later is extremely low.
The purpose of this report is to review the major effects of climate change on the agricultural sector; to examine the causes of vulnerability; and to suggest a range of potential options and investment opportunities for supporting adaptation efforts and, more generally, for building adaptive capacity. This report primarily focuses on appropriate strategies for adapting to climate change impacts that are projected to occur over the next one to two decades, although several issues covered in this report are important for long-term adaptation needs as well.
This paper shared lessons learnt from the project of Improving Productivity and Market Success in forage development approaches, scaling up strategies, opportunities and challenges in the process of farmer innovations and innovative interventions in the value-chain of market oriented livestock development in relation to sustainable use of natural resources in two districts in Ethiopia.
The USAID Building Agribusiness Capacity in East Timor (BACET) program was extended for three additional years in September 2008. Land O’Lakes gathered feedback from the Ministry of Agriculture, USAID, teachers and students and immediately initiated enhancements to improve the curriculum previously developed to reinforce practical and market-oriented skills.
Le gouvernement de Lula a considérablement amplifié et diversifié le Programme d’Appui à l’Agriculture Familiale (PRONAF), créé par le gouvernement Fernando Henrique Cardoso en 1995. Ce choix affirmé sur la longue durée pour l’agriculture familiale, peut surprendre dans un Brésil qui a toujours, tout au long de son histoire, privilégié l’agriculture « d’entreprise » : latifundia et entreprises agricoles.
