The role of mineral fertilizers in transforming agriculture in Indonesia
Indonesia is an archipelago consisting of 13,466 islands, which are divided into 33 provinces. Java, Bali, and Nusa Tenggara are the inner islands and contain 62 percent of the total population of 246 million, but only accounts for 8 percent of the total land area. The inner islands are naturally more fertile than the outer islands that have nutrient-poor, acidic soils. In theory, fertilizer use should be higher on the outer islands, but in reality outer island fertilizer use is generally lower, making crop yields lower, especially when compared to Java.
Understanding the role of research in the evolution of fertilizer policies in Malawi
This study examines the role of research in agricultural policy making in Malawi at a time when the Africa Union and the New Partnership for Africa’s Development have been seeking to promote greater evidenced-based decision making in agriculture. Drawing on both theory and actual past experiences documented in the literature, results are intended to improve our understanding of the extent to which research has played any role in influencing policy change in Malawi. This is done in the context of the evolution of the country’s fertilizer subsidy policies.
Efficiency and productivity differential effects of land certification program in Ethiopia: Quasi-experimental evidence from Tigray
Taking advantage of a unique quasi-experi-mental survey design, this study analyzes the productivity impacts of the Ethiopian land certification program by identify-ing how the investment effects (technological gains) would measure up against the benefits from any improvements in input use intensity (technical efficiency).
Medium and large-scale farmers and agricultural mechanization in Ghana: Survey results
This survey was planned and executed in order to address key policy and research questions which have arisen as priorities for the research agenda, but for which there has been a lingering data gap. Successful commercialization of farming enterprises and f
On farm conservation of rice biodiversity in Nepal: a simultaneous estimation approach
"This paper presents an empirical case study about farmer management of rice genetic resources in two communities of Nepal, drawing on interdisciplinary, participatory research that involved farmers, rice geneticists, and social scientists. The decision-making process of farm households is modeled and estimated in order to provide information for the design of community-based conservation programs.
Hydrological modeling of sustainable land management interventions in the Mizewa watershed of the Blue Nile Basin
This analysis utilizes recent hydrological and meteorological data collected from the Mizewa watershed in order to better understand the physical impact of SLWM investments. The effectiveness of the simulated conservation practices (terraces, bunds, and residue management) are evaluated using the Soil and Water Assessment Tool (SWAT) model taking into account investment decisions on different terrain types.
