Three Essays On Migration Decision, Migration Destination Choice, And Food Security: Evidence From Chitwan, Nepal, Madhav Regmi Jan 2014

Three Essays On Migration Decision, Migration Destination Choice, And Food Security: Evidence From Chitwan, Nepal, Madhav Regmi

LSU Master's Theses

This thesis research is based on data obtained from the Nepal Ethno Survey of Family, Migration and Development conducted in 396 farming households in the Eastern part of the Chitwan, Nepal. In a three essay thesis format, I explore the factors affecting migration decision and migration destination choices. I then establish a link between remittance and food security status of the surveyed households. In the first essay, I use a probit model to identify household decisions to send or not to send migrants, and identify factors affecting the decision process. I include individual, household and social network characteristics in the …

Measuring The Impacts Of Agricultural Input Subsidies In Sub-Saharan Africa: Evidence From Malawi's Farm Input Subsidy Program, Gerald E. Shively, Jacob Ricker-Gilbert Jun 2013

Measuring The Impacts Of Agricultural Input Subsidies In Sub-Saharan Africa: Evidence From Malawi's Farm Input Subsidy Program, Gerald E. Shively, Jacob Ricker-Gilbert

Purdue Policy Research Institute (PPRI) Policy Briefs

Malawi, a small, land-locked country in south Eastern Africa has been at the forefront of the recent push to reestablish subsidies as a way of boosting agricultural production and improving food security, especially among the poor. Its programs have been widely observed, scrutinized, and emulated. This policy brief examines Malawi’s Farm Input Subsidy Program (FISP) and distills a set of key research findings drawn from research conducted recently at Purdue University.

Estimating Crop Yield Potential At Regional To National Scales, Justin Van Wart, Kurt Christian Kersebaum, Shaobing Peng, Maribeth Milner, Kenneth Cassman Jan 2013

Estimating Crop Yield Potential At Regional To National Scales, Justin Van Wart, Kurt Christian Kersebaum, Shaobing Peng, Maribeth Milner, Kenneth Cassman

Department of Agronomy and Horticulture: Faculty Publications

World population will increase 35% by 2050, which may require doubling crop yields on existing farm land to minimize expansion of agriculture into remaining rainforests, wetlands, and grasslands. Whether this is possible depends on closing the gap between yield potential (Yp, yield without pest, disease, nutrient or water stresses, or Yw under water-limited rainfed conditions) and current average farm yields in both developed and developing countries. Quantifying the yield gap is therefore essential to inform policies and prioritize research to achieve food security without environmental degradation. Previous attempts to estimate Yp and Yw at a global level have been too …

Yield Gap Analysis With Local To Global Relevance—A Review, Martin K. Van Ittersum, Kenneth Cassman, Patricio Grassini, Joost Wolf, Pablo Tittonell, Zvi Hochman Jan 2013

Yield Gap Analysis With Local To Global Relevance—A Review, Martin K. Van Ittersum, Kenneth Cassman, Patricio Grassini, Joost Wolf, Pablo Tittonell, Zvi Hochman

Department of Agronomy and Horticulture: Faculty Publications

Yields of crops must increase substantially over the coming decades to keep pace with global food demand driven by population and income growth. Ultimately global food production capacity will be limited by the amount of land and water resources available and suitable for crop production, and by biophysical limits on crop growth. Quantifying food production capacity on every hectare of current farmland in a consistent and transparent manner is needed to inform decisions on policy, research, development and investment that aim to affect future crop yield and land use, and to inform on-ground action by local farmers through their knowledge …

Impact Of Hybrid Rice On Food Security: A Spatial Equilibrium Analysis Of Global Adoption And Diffusion Of Hybrid Rice Varieties, Till Ludwig Aug 2012

Impact Of Hybrid Rice On Food Security: A Spatial Equilibrium Analysis Of Global Adoption And Diffusion Of Hybrid Rice Varieties, Till Ludwig

Graduate Theses and Dissertations

Rice is the staple crop for most consumers in Asia. More than half of the global population depends on rice. However, scarce resources for agricultural production and unfavorable conditions will make it hard to meet future demand in rice and threaten future food security. Hybrid rice technology is a method to increase the productivity of resources needed for rice production. Current developments show not only yield improvements in comparison to existing conventional and hybrid varieties, but also fuel hopes for new abiotic and biotic stress tolerance. The objective of this study is to determine what impact hybrid rice varieties can …
