Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws
School of Natural Resources: Dissertations, Theses, and Student Research
Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …

Essays On Conservation Outcomes On Rented Farmland-Role Of Gender, Diya Ganguly
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The essays in this dissertation explore why female landowners may be less likely than male landowners to achieve long term conservation on their land. In Chapter 1 we develop theory to model the strategic interaction between a landowner and a tenant with a focus on their gender and implementation of conservation practices on land. Within the context of a sequential-move game, we use the principal-agent framework and identity theory to model land-use choice and equilibrium payoffs between landowner and tenant. We consider cash rent lease and discounted lease whereby the tenant pays a reduced rent if they implement conservation practices …

A Perusal On Preservation And Conservation Techniques In The Government Aided College Libraries Of Diamond Harbour And Alipore Subdivision In South 24 Parganas, Bibhash Ram Singha, Bikash Kumar Halder
Library Philosophy and Practice (e-journal)
The present study is exhibited the preservation and conservation techniques in the college libraries of Diamond Harbour and Alipore subdivisions in the district of South 24parganas. It also discusses degradation problems of print and non-print materials, causes of deterioration of library documents, and different obstacles to using preservation techniques. To secure the library materials in a good manner need to apply the preservation and conservation techniques which include cleaning and dusting, use of insecticides and insect repellent such as Thymol, Dichlorovos, Dursban, Naphthalene balls, Neem leaf, etc., besides that there is a provision for security systems of the college libraries …
