Phd Thesis (Doctorat De Spécialité): Université De Ouagadougou, 1999. Dr. Mamoudou H. Dicko. Purification Et Propriétés Physico-Chimiques Des Enzymes De Curculigo Pilosa, Gladiolus Klattianus Et Boscia Senegalensis Catalysant L'Hydrolyse Des Polysaccharides (Amidon Et Béta-Glucanes), Mamoudou H. Dicko Prof.

Pr. Mamoudou H. DICKO, PhD

The objective of this study was the research of novel and inexpensive sources of polysaccharides degrading enzymes such as amylases and glucanases from local plants in order to justify their biotechnological applications. The isolation of two l3-amylases and an endo-1,3-ß-D-glucanase was reached using common protein purification methods such as buffer extraction, ammonium sulfate fractionation, ionexchange and gel filtration chromatographies. The methods used were simple and easily reproducible, suggesting the possibilfty of large-scale production. ln the crude extract of Curculigo pilosa tuber, only ß-amylase was detected as starch degrading enzyme and its activity was approximately 282 Uig of fresh material. The …

Institutional Changes And Discretionary Value For Property Rights In Drylands’ Farming Of The Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Research on land tenure and use control and the socioeconomic sets of regulations in the agricultural rainfed sub sector of Sudan, come to focus for many reasons. Anthropogenic pressure, expanding animal population and migration led to accelerated impacts on both the ecological systems and land yields. Conflicts between governmental regulations and indigenous rules contribute to generate inconsistencies on who have the right to till the land and hence own it. With such transformation logically, more intensive commercial farming took place and land intake exponentially increased. Private or collective property rights of land are procured through traditional tenure, prescription, settlement or …

Analysis Of Intersectoral Linkages Between Agriculture And Industry In Nigeria, M I. Abudu

CBN Occasional Papers

This paper uses time series data to analyse the relationship between agricultural growth and industrial performance for the three-decade period 1966 - 1995. Agricultural growth influences industry in many ways. It provides the raw materials needed by industry; it creates direct demand for the output of consumption goods of industries and indirect demand for the output of basic and capital goods industries. Analysing the input-output coefficients, the paper found that most primary and secondary commodity groups have weak backward and forward linkages, while the quantitative relationships between agricultural growth and industrial performance were non-significant, even when lagged. However, the link …

Winners And Losers In A World With Global Warming: Noncooperation, Altruism, And Social Welfare, Arthur J. Caplan, Christopher J. Ellis, Emilson C. D. Silva

Water Balance-Related Performance Indicators For International Projects, Charles M. Burt, Stuart W. Styles

BioResource and Agricultural Engineering

A unique study to examine the impacts of irrigation project modernization was funded by the Research Committee of the World Bank and managed by the International Program for Technology Research in Irrigation and Drainage (IPTRID). The project examined 16 irrigation projects in 10 developing countries, 15 of which have been partially modernized in some aspects of hardware and/or management. Besides developing specific recommendations for donor agencies interested in irrigation project modernization, this project also accomplished the following: 1. A Rapid Appraisal Process (RAP) was developed to quickly (within a week) evaluate an irrigation project to assess what type of modernization …

Tb171: Investigations Into The Potential Of Measuring Biodiversity In Maine's Forests With Forest Inventory And Analysis (Fia) Data, Thomas G. Allen, Andrew Plantinga

Technical Bulletins

We present here the results of our initial effort to use FIA data to assess biodiversity in Maine's forests. Biodiversity is a complex issue and, from the start, it was apparent that the FIA data are inadequate for examining all facets of biodiversity. Nevertheless, the FIA provides the most comprehensive and detailed data on Maine's forests and can be used to measure some indicators of forest biodiversity, in particular those related to tree species and stand characteristics.

Are There Ways To Enhance China's Food Security?, B. Gardner Delworth, Yahui Zhao

Faculty Publications

Chinese officials and newspapers express considerable concern about the country's capacity to feed its huge and still growing population. The rhetoric will be familiar to people in Western countries as a blend of "agrarian fundamentalism" and "Malthusianism." But beyond the official rhetoric, we will argue that reforms in land ownership and irrigation water pricing and management could have highly salutary impacts on agricultural output that could alleviate food shortages far into the future.

Evaluation Of Subsurface Drip Irrigation On Peppers, Stuart W. Styles, Charles M. Burt

BioResource and Agricultural Engineering

This paper is a summary of two farms that utilized the California Energy Commission's low-interest loan program to facilitate their entry into drip irrigation. One farm is located near Oxnard, California, USA and the other is located near Gilroy, California, USA. Both of these growers farm about 162 hectares (400 acres) in their overall operations and used the loans to purchase subsurface drip irrigation systems for Peppers. Over $4 million in low-interest loans have been made available to California growers from the California Energy Commission (CEC) since 1986. The CEC initiated the loan program for growers to help implement energy …

The Value Of Additional Central Flyway Wetlands: The Case Of Nebraska's Rainwater Basin Wetlands, P. Joan Poor

Department of Agricultural Economics: Faculty Publications

Waterfowl habitat is a biological resource which is neither bought nor sold in the traditional market sense. Nebraska, which is situated near the center of the North American Central Flyway, contains unique wetland habitat. Recognizing this, resource managers working in Nebraska promote regulatory protection of such areas. This study found that Nebraskans positively value their state's Rainwater Basin wetland region in that they are willing to pay to have it maintained and expanded. In addition, this study demonstrates how this value was estimated and illustrates how such a value can assist in policy decisions regarding habitat acquisition programs.

Amenities And The Labor Earnings Function, Philip E. Graves, Robert L. Sexton

PHILIP E GRAVES

Desirable locations are, other things equal, expected to be characterized by a mix of higher rents or lower wages. That is, if one area is more attractive than others, inmigration would occur, driving up the demand for land (hence raising rents) and increasing the supply of labor (hence lowering wages). The in-movement will continue until utility is the same across locations in equilibrium. Failing to hold constant amenities in the traditional earnings functions employed by labor economists will result, then, in omitted-variable bias if worker characteristics (years of schooling, union membership, and so on) are correlated with amenities. By way …

Amenities And Fringe Benefits: Omitted Variable Bias, Philip E. Graves, Robert L. Sexton, Michelle M. Arthur

PHILIP E GRAVES

If labor is fairly mobile, as it is in the United States, one would expect that households would move from less desirable areas toward more desirable areas until all areas are equally desirable. The way that areas become equally desirable is through the impact of movers on wages and rents (and possibly "endogenous" disamenities, such as congestion or pollution). That is, as people move to desirable areas, they will increase the demand for land (raising rents) and increase the supply of labor (lowering wages); in equilibrium, the wage and rent "compensation" for the niceness of an area reveals, in dollar …

The Historical Development Of Agriculture In Illinois, Pamela Riney-Kehrberg

Pamela Riney-Kehrberg

Illinois' agricultural history is long and complex. Illinois' first settlers, the Native Americans, practiced hunting, gathering, and fishing and made use of the resources of the woods and prairies. By the tenth century, Native Americans combined men's hunting with women's agricultural activities to meet the needs of their communities. The earliest crop Native American women cultivated was corn, imported to Illinois from the Southwest.

Book Review: Pigs, Profits, And Rural CommunitiesBy Thu, Kendall M., & Durrenberger, E. Paul (Eds.), E. Wesley F. Peterson

Department of Agricultural Economics: Faculty Publications

Early in their introductory comments, the editors of this book claim that they “are not political activists and that [they] neither promote nor defend industrial agriculture based on any political agenda” (p. 4). Industrial agriculture, as understood in this book, includes large corporations, vertically integrated firms, multinationals, and anything else that seems to differ from what might be thought of as a traditional family farm. The editors suggest that their goal is to provide objective assessments of one example of industrial agriculture, large-scale hog confinement operations. However, as the introduction progresses, strange things seem to happen to this perfectly sensible …

The World Food And Agricultural Situation - A U.S. Perspective, Clayton K. Yeutter

Clayton K. Yeutter, U.S. Secretary of Agriculture Papers

It is a pleasure to be here in Minnesota at this year's Global Food and Agriculture Summit. And it is a special pleasure to share the podium today with lots of long-time friends, many of whom have forever been associated with American agriculture. would like to focus today on what kind of future might be ahead of us all as we contemplate the excitement of entering a new century. As we look back, we can only conclude that the 20th century was mighty exciting too, and assuredly challenging from an agricultural policy standpoint.

Measures Of Welfare Effects In Multiproduct Industries: The Case Of Multispecies Individual Quota Fisheries, Niels Vestergaard

Niels Vestergaard

A framework is developed to measure the welfare effects of individual quota reforms in multiproduct industries using the multimarket welfare measure techniques suggested by Just, Hueth, and Schmitz (1982) and the concept of virtual price in the production theory literature (Neary 1995; Squires and Kirkley 1996). Under joint in input production it shown that quasirent under a single quota can be measured by the producer surplus either in the output market for quota output or in the quota market. Under multiple quotas the welfare effects of quota policies can be measured in one of the quota markets using inverse derived …
