Evaluation Of The Brazilian Agrarian Reform Objective: Agricultural Production Yield Change, Tiffany Kwader Harbour Jan 2017

Evaluation Of The Brazilian Agrarian Reform Objective: Agricultural Production Yield Change, Tiffany Kwader Harbour

Walden Dissertations and Doctoral Studies

Brazil has an active agrarian reform policy program, publicly organized by the federal government and publicly administered at the state level by the National Institute for Colonization and Agrarian Reform. The objective of the agrarian reform policy program is to retitle unproductive and underproductive rural lands to increase agricultural production and land use. Previous agrarian reform researchers have examined quantities of land redistributed, rural technology developments, and the impact of social movements on land redistribution, but a knowledge gap remains regarding the correlation of agricultural production yields in rural municipalities before and after policy program participation. The State of Cearà ...


Impact Of The Zambian Agricultural Policy On Grain Trade, Onesphore Karuho Jan 2017

Impact Of The Zambian Agricultural Policy On Grain Trade, Onesphore Karuho

Walden Dissertations and Doctoral Studies

The agricultural sector in Zambia is supported through the government use of public expenditure programs to spur the production and subsidize the consumption of key grains to stabilize prices. Previous research has documented the effects of public spending on agriculture in terms of food prices and food security. The effects of government spending on the trade of key grains, however, is not well understood. As such, there is a gap in knowledge regarding the impact of agricultural policy on the agricultural trade. The purpose of this study was to determine the impact of Zambian agricultural policy on grain trade. A ...


Strategies For Preventing And Mitigating The Effects Of Agro-Food Supply Chain Disruptions, Everjoyce Muzvondiwa Jan 2017

Strategies For Preventing And Mitigating The Effects Of Agro-Food Supply Chain Disruptions, Everjoyce Muzvondiwa

Walden Dissertations and Doctoral Studies

Supply chain disruptions are detrimental to the performance of companies due to the associated loss of profitability and reduced sustainability. In 2016, organizations lost at least $1.2 million in a single supply chain disruption. Guided by the contingency theory of fit, the purpose of this exploratory multiple case study was to explore the strategies agribusiness managers use to prevent and mitigate the effects of disruptions in the agro-food supply chains. A total of 5 purposefully-selected agribusiness managers from Harare, Zimbabwe participated in semistructured interviews. Participants were senior agribusiness managers who implemented successful strategies for preventing and mitigating the effects ...


Evaluating The Impact Of Policies On Production Efficiency Of Nigeria's Rice Economy, Samuel Chukwueyem Rapu Jan 2016

Evaluating The Impact Of Policies On Production Efficiency Of Nigeria's Rice Economy, Samuel Chukwueyem Rapu

Walden Dissertations and Doctoral Studies

Nigeria, like all other rice consuming nations, has experienced a surge in domestic demand for rice since 1970. However, local rice production has not been sufficient to meet local demand, leading to this demand continually being filled by imports. The Federal Government of Nigeria has initiated subsidies programs intended to improve Nigerian rice farmers' technical and cost efficiency levels. This quantitative study evaluated the impact of these policies on the technical and cost efficiency levels of paddy rice farm households in Nigeria. Farrell's (1957) efficiency theory and production theory served as the theoretical frameworks. Data were collected from a ...


A Quantitative Analysis Of The Effect Of Cash-4-Grass Programs On Water Consumption, Cynthia Allen Jan 2014

A Quantitative Analysis Of The Effect Of Cash-4-Grass Programs On Water Consumption, Cynthia Allen

Walden Dissertations and Doctoral Studies

Water supplies in California are stretched to critical levels as a result of population growth, periodic drought, and climate change. The California legislature recognized that the best way to increase supply is to decrease demand so the Water Use Efficiency Senate Bill 7 (SBx7-7) was signed into law in 2009. The law requires water purveyors to reduce per capita water usage by 20% by the year 2020. To comply, water purveyors are searching for innovative ways to increase water conservation. A review of the literature has shown that many factors influence water consumption. However, the majority of household water consumption ...


Exploring Income Supplementation For Farm Sustainability, Elizabeth P. Persson Jul 2013

Exploring Income Supplementation For Farm Sustainability, Elizabeth P. Persson

Walden Dissertations and Doctoral Studies

Sustainable farms are critical to United States’ food independence and they positively contribute to the global economy. Farms in the United States are not sustainable without profitable supplemental income. The purpose of this case study was to explore the historic profitability of farm income supplementation methods. Maslow’s hierarchy of needs theory served as the conceptual framework. A purposive sample of 25 farmers from 5 regions of the continental United States completed semistructured interviews and described their personal experiences. Archival supplemental income data came from the United States Department of Agriculture census. All the data were analyzed using coded keywords ...
