A lo largo del trabajo se resume la interacción histórica entre los contratistas y la agricultura como una forma de caracterizar a estos empresarios y resaltar los aspectos que han influido en su expansión, convirtiéndolos en una peculiaridad de la agricultura argentina. Este repaso ofrece claros indicios sobre la hipótesis planteada -luego confirmados con información estadística- que, además, permite medir el peso de estos actores en la economía y su evolución reciente
Este documento analiza los temas emergentes y sus implicancias respecto a las políticas de desarrollo. La sección 2 aborda las tendencias en la expansión de los supermercados en los países en desarrollo, y la sección 3 analiza los factores determinantes del fenómeno.

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.
Science and technology (S&T) are major contributors to food security, poverty reduction, and economic growth, as has been proven in Asia since the early-1970s through the Green Revolution in agriculture. Continuing to secure such gains, however, is becoming an increasingly complex undertaking. More than ever, quantitative data are vital for measuring, monitoring, and benchmarking the performance of agricultural S&T systems, including their inputs and outcomes.
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.
