Impact of Improved Maize Varieties on Food Security in Eastern Zambia

Book Description
This study investigates the impact of improved maize varieties on household food security in eastern Zambia using household survey data from a sample of over 800 rural households. Since treatment effect estimates are often prone to misspecification in either the treatment or outcome equation, we use the doubly robust inverse probability weighted regression adjustment method, complemented with propensity score matching on six different food security measures to obtain reliable impact estimates. Generally, we find a positive impact of improved maize adoption on food security across the two econometric approaches. Maize being the most important food staple in Zambia has a great bearing on the food security status of farm households. It is therefore imperative that a conducive environment is created that promotes the adoption of maize yield improving technologies.

Drought Stress in Maize (Zea mays L.)
Author: Muhammad Aslam
Publisher: Springer
ISBN: 3319254421
Category : Science
Languages : en
Pages : 79
Book Description
This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

Globalization and Poverty
Author: Ann Harrison
Publisher: University of Chicago Press
ISBN: 0226318001
Category : Business & Economics
Languages : en
Pages : 674
Book Description
Over the past two decades, the percentage of the world’s population living on less than a dollar a day has been cut in half. How much of that improvement is because of—or in spite of—globalization? While anti-globalization activists mount loud critiques and the media report breathlessly on globalization’s perils and promises, economists have largely remained silent, in part because of an entrenched institutional divide between those who study poverty and those who study trade and finance. Globalization and Poverty bridges that gap, bringing together experts on both international trade and poverty to provide a detailed view of the effects of globalization on the poor in developing nations, answering such questions as: Do lower import tariffs improve the lives of the poor? Has increased financial integration led to more or less poverty? How have the poor fared during various currency crises? Does food aid hurt or help the poor? Poverty, the contributors show here, has been used as a popular and convenient catchphrase by parties on both sides of the globalization debate to further their respective arguments. Globalization and Poverty provides the more nuanced understanding necessary to move that debate beyond the slogans.

Coping with Risk in Agriculture, 3rd Edition
Author: J Brian Hardaker
Publisher: CABI
ISBN: 1780645740
Category : Business & Economics
Languages : en
Pages : 290
Book Description
Risk and uncertainty are inescapable factors in agriculture which require careful management. Farmers face production risks from the weather, crop and livestock performance, and pests and diseases, as well as institutional, personal and business risks. This revised third edition of the popular textbook includes updated chapters on theory and methods and contains a new chapter discussing the state-contingent approach to the analysis of production and the use of copulas to better model stochastic dependency. Aiming to introduce agricultural decision making, probability and risk preference, this book is an indispensable guide for students and researchers of agriculture and agribusiness management.
