Este libro describe la actuación del proyecto “Gestión de riesgo de desastres naturales con enfoque de seguridad alimentaria en el departamento de Arequipa”, abreviado como PGRD-COPASA y busca sistematizar los resultados y las conclusiones de modo tal que puedan servir de inspiración para proyectos nuevos o en curso, que trabajan en la misma temática o en un entorno comparable.
Este artículo tiene como principal objetivo discutir un método para el desarrollo de proyectos de viabilidad y atracción de inversiones en el cual se considere la vertiente de la sustentabilidad económica, pero también la social y la ambiental. El artículo muestra primero la importancia de una orientación para mercado de un proyecto en agronegocio que tradicionalmente estuvo más orientado a la producción. Luego, sugiere cuatro dimensiones fundamentales para que sean incorporadas en proyectos de viabilidad en agronegocios.
Maize production is of critical importance to smallholder farmers in Ghana. Various factors limit the productivityof smallholder maize farming systems undergirded by the lack of capital for critical investments both at the farmand at national policy levels. Using a value chain approach, this diagnostic study explains how a complex configuration of actor interaction within an institutionally and agro-ecologically challenged value chain leads tothe enduring absence of maize farming credit support.
Globalization, urbanization and new market demands - together with ever-increasing quality and safety requirements - are putting significantly greater pressures on agrifood stakeholders in the world. The ability to respond to new challenges and opportunities is important not just for producers but also for industries in developing countries. This paper aims to present what "innovation response capacity" entails, especially for natural resourcebased industries in a developing country context.
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
The privatization of agricultural research and extension establishments worldwide has led to the development of a market for services designed to support agricultural innovation. However, due to market and systemic failures, both supply side and demand side parties in this market have experienced constraints in effecting transactions and establishing the necessary relationships to engage in demand-driven innovation processes.
This paper examines the role of postsecondary agricultural education and training (AET) in sub-Saharan Africa in the context of the region’s agricultural innovation systems. Specifically, the paper looks at how AET in sub-Saharan Africa can contribute to agricultural development by strengthening innovative capacity, or the ability of individuals and organisations to introduce new products and processes that are socially or economically relevant, particularly with respect to smallholder farmers who represent the largest group of agricultural producers in the region.
