Environmental Conservation On Agricultural Working Land: Assessing Policy Alternatives Using A Spatially Heterogeneous Land Allocation Model, Kelly M. Cobourn

Electronic Theses and Dissertations

Multifunctionality refers to the ability of agricultural systems to produce an array of non-market goods and services in addition to market commodities. This thesis focuses explicitly on the provision of environmental benefits, through reduced soil erosion and fertilizer applications, by agricultural producers. Soil erosion and nutrient contamination from agricultural production are the foremost contributors to ground and surface water degradation in the United States. Reducing their production implies gains in social welfare, but may generate significant private losses to producers. The objective of this analysis is to quantify the tradeoff between environmental improvements and producer welfare and to examine the …

OBJECTIVE: The objective of this study was to examine the receptivity for probiotic products among premenopausal female students in an African university. GOAL: The goal of this study was to determine the local knowledge in Nigeria of probiotics and the willingness of young women to use them should they be introduced. STUDY: Closed-ended questionnaires were administered to a sample of 280 participants and these addressed age, marital status, perceived risk of HIV infection for the next 3 years, and history of urogenital infections. The participants were also asked whether they would welcome a probiotic product in oral/vaginal form and in …

Application Of Response Surface Methodology For Studying The Product Characteristics Of Extruded Rice-Cowpea-Groundnut Blends, Emmanuel Asare, Samuel Sefa-Dedeh, Emmanuel Ohene Afoakwa

Professor Emmanuel Ohene Afoakwa

Response surface methodology (with central composite rotatable design for k=3 was used to investigate the product properties of extruded rice-cowpea-groundnut blends in a single screw extruder. The combined effect of cowpea (0-20%), groundnut (0-10%), and feed moisture (14-48%) levels were used for formulation of the products. The product moisture, expansion ratio, bulk density and total colour change were studied using standard analytical methods. Well-expanded rice-legume blend extrudates of less bulk density and lower moisture content were produced at low feed moisture. Increasing legume addition affected the various shades of colour in the product. Models developed for the indices gave R2 …

The Microflora Of Fermented Nixtamalized Corn, Samuel Sefa-Dedeh, Beatrice Cornelius, Wisdom Amoa-Awua, Esther Sakyi-Dawson, Emmanuel Ohene Afoakwa

Professor Emmanuel Ohene Afoakwa

Nixtamalization is a traditional process that improves the nutritional quality of corn. To provide a means of utilizing the nutritional benefits of nixtamalized corn and improve product acceptability, lactic acid fermentation was applied. The objective of the study was to study the microbial profile and establish the important lactobacilli of fermenting nixtamalized corn dough. Two batches of cleaned whole corn were subjected to the process of nixtamalization, using two concentrations of lime (0.5 or 1.0%), milled, made into a dough (50% moisture) and fermented spontaneously for 72 h. A control sample was prepared without alkaline treatment. pH and titratable acidity …

Effects Of Cowpea Fortification, Dehydration Method And Storage Time On Some Quality Characteristics Of Maize-Based Traditional Weaning Foods., Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh, Esther Sakyi-Dawson

Professor Emmanuel Ohene Afoakwa

Fortification of cereal-based traditional foods with legume protein can improve their nutritional value. It is, however, important to find out the extent to which the addition of cowpea affects the desirable quality characteristics of traditional weaning foods prepared from fermented maize and also to assess the effect of dehydration method and storage time on the chemical, physico-chemical and functional properties of the products. A 3 x 2 x 4 factorial experiment with cowpea level, drying method and storage time as the respective variables was done. The traditional weaning food was prepared by steeping maize in water for 24 hours, mixed …

Comparison Of 'Organic' And 'Conventional' Grains And Soybean Prices In The Northern Great Plains And Upper Midwest: 1995 Through 2003, Nicholas Streff, Thomas L. Dobbs

Economics Pamphlet Series

Price premiums for organic crops drew the attention of an increasing number of farmers throughout the 1990s. Premiums contributed to the expansion of U.S. farmland managed under organic farming systems during that time period. Expansion of organic farming systems continued at least through 2001. According to the U.S. Department of Agriculture (USDA) Economic Research Service's most recent data on organic farming systems, U.S. farmers and ranchers added almost one million acres of certified organic farmland between 1997 and 2001, an increase of 74 percent. Over that same time frame, certified organic cropland increased by 53 percent). The USDA implemented national …

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko

Pr. Mamoudou H. DICKO, PhD

The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …

Frontline Demonstration On Sesame In West Bengal, Ganesh Chandra, R L. Sagar

Ganesh Chandra

Sesame is one of the important oilseeds crop in India, which plays a major role in supplementing the income of small and marginal farmers of Sunderbans. One of the major constraints of traditional Sesame farming is low productivity of local varieties. To replace this anomaly, Krishi Vigyan Kendra of CIFRI has conducted frontline demonstration at adopted farmers’ field in four development blocks viz. Kakdwip, Namkhana, Patharpratima and Kulpi of Sunderbans, West Bengal. Cultivation of high yielding varieties of Sesame viz. Rama (Improved Selection-5) and Tilottma (B-67) shows percentage increase of 46.58 and 35.86 respectively over local check. The technology gap …

Effect Of Nixtamalization On The Chemical And Functional Properties Of Maize, Samuel Sefa-Dedeh, Beatrice Cornelius, Emmanuel Ohene Afoakwa

Professor Emmanuel Ohene Afoakwa

The high utilization and consumption levels of maize in developing countries calls for investigations into new methods of processing to help introduce variety as well as improve the functionality and nutrient quality of maize-based foods. This study was carried out to determine the effect of nixtamalization on the chemical and functional characteristics of maize. A 2X4 factorial experimental design with cooking time (0, 30 min) and lime concentration (0, 0.33, 0.5 and 1.0%) was performed. Chemical composition (moisture, protein and ash), pH, titratable acidity, water absorption, colour, cooked paste viscosity and texture were determined using standard methods. The cooking time …

Biotechnology And The Law: A Consideration Of Intellectual Property Rights And Related Social Issues, Michael D. Mehta

The University of New Hampshire Law Review

[Excerpt] “Recent advances in biotechnology are expected by many to improve crop yield, reduce reliance on agricultural inputs like pesticides and herbicides, alleviate world hunger, improve the safety and effectiveness of pharmaceuticals, assist in the discovery of genes that trigger diseases like cancer, and make more efficient our legal institutions through DNA testing. Clearly, innovations in biotechnology are a powerful force for social change, and they pose unique challenges and opportunities for legal scholars and institutions. This section of the Pierce Law Review focuses on the interface between law and technology by examining how innovations in biotechnology accelerate debates about …
