Agricultural Productivity In Mercosur, Preeti Bharati

Dissertations and Theses in Agricultural Economics

This thesis applies econometric methods to investigate reported decline in productivity in the countries of Mercosur in Latin America. While non-parametric methods in general claimed thus, more recent studies using parametric approach exhibited mixed results. We show that the results are contingent to the estimation method employed, the dataset used and the degree of diversity in socio-political and economic environment prevailing in the countries analysed. Our results indicate that the region is experiencing 2.24% productivity growth dominated by technical growth (1.97%) and marred by low efficiency (0.24%), the latter being explained primarily by the quality of human ...

The Benefits of a Manure-based Biochar: Mike McGolden

Biochar has been in existence for thousands of years. However, it has only been in the past decade that there has been a resurgence in the thirst for knowledge about biochar and research into how it is made and its impact on the environment.

This resurgence has brought about a tremendous amount of research and a rapid growth in education among the general population about biochar – especially in the past 5 years. However, this history and almost all of the research has been with wood-based biochars. The use of manure as the feedstock to produce biochar is very limited; but the benefits are significant and also different from those of traditional wood-based biochars. The nutrient composition of the biochar from manure offers additional benefits not seen from other biochars. It also has a virtually unlimited supply of feedstock and in volumes that allow for larger systems without costly transportation of fuel. On the other hand, the use of manure as a fuel presents some technological challenges that wood does not.

Environmentally and economically, manure-based biochar can provide the solution to many of the problems facing agriculture today.

Rescuing biochar: Pre - application techniques to enhance plant responses to biochar additions: Nigel Gale, U of Toronto

A growing body of literature indicates variable responses of different plant species to biochar, including positive, neutral, and negative, suggesting that it is important to investigate the nature and mechanism of species-specific responses to biochar additions. Neutral or negative plant responses to additions of biochars have commonly been reported in prior studies, and are likely the result of a combination of changes in soil properties (e.g. pH, surface area, and nutrient and water retention) and the production of volatile organic compounds from ...

Novel Uses Of Biochar, Hans-Peter Schmidt

USBI Biochar Conferences

Cascading Uses of Biochar - Hans-Peter Schmidt, Ithaka Institute

In addition to the use of biochar as a soil amendment, there are an increasing number of ways to incorporate biochar into different eco- and industrial systems. Thus feeding biochar to livestock has numerous benefits not only for the animals, but it also helps reduce greenhouse gas emissions and improves nutrient retention in animal manure. The use of biochar in building materials is just beginning to be studied but shows promise in the ability to insulate, decontaminate air, provide odor and humidity control. Biochar as pillow filling to induce perfectly reposing sleep ...

Ethics & Sustainability, Gloria Flora, John Bonitz, Karen Ribeiro

USBI Biochar Conferences

Biochar and the Sustainability Imperative. Now marks a critical time: as biochar comes of age and markets begin to develop, this young industry is attracting naysayers, doubters and get-rich-quick-schemers. Ethical biochar production and use is of paramount importance as we continue to lay the groundwork for biochar as a model for carbon neutral/negative business, landscape restoration and truly green technology. Shortcuts, poor quality product and unsustainable use of biomass could bring biochar to its knees before it gains the traction necessary to fulfill its promises. This discussion will explore opportunities and pitfalls in feedstocks sustainability, production integrity and ethics ...

A Guide To Quasi-Experimental Designs, Matt Bogard

Matt Bogard

Linear regression is a very powerful empirical tool that allows for controlled comparisons of treatment effects across groups. However, omitted variable bias, selection bias, and issues related to unobserved heterogeneity and endogeneity can bias standard regression results. Quasi-experimental designs including propensity score methods, instrumental variables, regression discontinuity, and difference-in-difference estimators offer an inferentially rigorous alternative for program evaluation. In this guide, I begin with an introduction to the potential outcomes framework for rigorously characterizing selection bias and follow with discussions of quasi-experimental methods that may be useful to practitioners involved in program evaluation.

The Money Of Qaroon And The Patience Of Ayoub: Women And Land In Egypt's Mubarak Resettlement Scheme, Dina Najjar

University of Western Ontario - Electronic Thesis and Dissertation Repository

This dissertation addresses the challenge of achieving increased empowerment and equality for Egyptian women. The dissertation tests the assumption that land access (through both joint and full titles) increases empowerment and equality for women in two desert resettlements of Sa’yda and Intilaq, part of the massive Mubarak Resettlement Scheme (MRS). In particular, the dissertation identifies: 1) how land access could empower Egyptian women and 2) women’s experiences with land access in the MRS. Findings reveal that land access is indeed the most promising route for women’s advancement in life, but the desert land required patience and financial ...

Farm-Scale Costs And Returns For Second Generation Bioenergy Cropping Systems In The Us Corn Belt, Robert K. Manatt, Arne Hallam, Lisa A. Schulte, Emily A. Heaton, Theodore P. Gunther, Richard B. Hall, Kenneth J. Moore

Natural Resource Ecology and Management Publications and Papers

While grain crops are meeting much of the initial need for biofuels in the US, cellulosic or second generation (2G) materials are mandated to provide a growing portion of biofuel feedstocks. We sought to inform development of a 2G crop portfolio by assessing the profitability of novel cropping systems that potentially mitigate the negative effects of grain-based biofuel crops on food supply and environmental quality. We analyzed farm-gate costs and returns of five systems from an ongoing experiment in central Iowa, USA. The continuous corn cropping system was most profitable under current market conditions, followed by a corn–soybean rotation ...

Why I Love Grasshopper Sparrows, Michele Patenaude

UVM Libraries Conference Day

Since 2001, Michele (a library circulation supervisor in her day job) has conducted a summer breeding-bird survey of Grasshopper Sparrows at Camp Johnson in Colchester, VT. Named Grasshopper Sparrows because their breeding call sounds like a grasshopper, this little brown bird is endemic to certain types of scrubby grasslands which are becoming more scarce in the Northeast. The Grasshopper Sparrow is also declining and the species is not on the list of Vermont Endangered Birds. Come to this presentation and learn about the bird, how Michele surveys them, why they are endangered, and why Michele loves these quiet, little brown ...

Agricultural Biotechnology, International Trade, General Equilibrium And Efficiency, Comlanvi Martin Konou

Dissertations and Theses from the College of Business Administration

Ongoing debates about the adoption of the agricultural biotechnology in the developing countries and EU have dominated the literature in development economics and biosciences. This dissertation considers some environmental, economic and social consequences of the technology from three perspectives: 1) the impact of the ongoing pest density on the performance of the agricultural biotechnology in India; 2) trade consequences of EU restrictive trade policies towards biotech products; and 3) the adoption decision of the technology in the EU and the developing economies.

Agricultural biotechnology appears to be successful in increasing yield and reducing the use of pesticides. However, most studies ...

The Impact Of The African Growth And Opportunity Act (Agoa): An Empirical Analysis Of Sub-Saharan African Agricultural Exports, Addisalem Zenebe

Dissertations and Theses in Agricultural Economics

The African Growth and Opportunities Act (AGOA) which was signed into law in 2000 as part of U.S. trade legislation has the objectives of increasing trade and investment between the U.S. and eligible Sub-Saharan African (SSA) countries, by reducing or eliminating tariffs applied to African exports of different products. This Act represents a promising approach to economic growth and development in SSA through international trade.

This thesis examines the impact of AGOA on African agricultural exports. The study uses the gravity trade model framework and panel data depicting annual agricultural trade from 35 eligible SSA countries to the ...

Overcoming Barriers To Local Food Access: A Case Study, Brittany Ryan

Masters Theses & Specialist Projects

This thesis focuses on the idea that food insecurity and access are real issues in the lives of many Americans. Simply stated, food insecurity is when a person does not have enough food to eat or does now know where his/her next meal is coming from. More importantly when looking at food insecurity is the realization that healthy, local food access is even more prevalent an issue – with increasingly more under-resourced individuals and families being food insecure and unhealthy at the same time. This thesis includes a literature review on diet and nutrition in the United States, a chapter ...

Assessing The Influence Of Conservation Agriculture On Household Wellbeing And Maize Marketing In Tete And Manica Mozambique, William Edward Mcnair

Masters Theses

In recent years there has been a movement on the part of farmers, governments, Non-Governmental Organizations (NGO), and the international community to promote the use of sustainable agricultural practices. In Sub-Saharan Africa, this has translated into programs with the expressed aim of increasing smallholder farmer adoption rates of conservation agriculture (CA). This thesis contributes to the analysis of the adoption of conservation agriculture by smallholder farmers in Sub-Saharan Africa by assessing the economic status of CA adopters in the providences of Manica and Tete, Mozambique.

Chapter II of the thesis examines the ceteris paribus correlation between smallholder farm household economic ...

A Gis-Based Multi-Objective Optimization Of A Lignocellulosic Biomass Supply Chain: A Case Study In Tennessee, Zidong Wang

Masters Theses

To achieve an economically and environmentally sustainable lignocellulosic biomass (LCB)-based biofuel industry sector, the design and location of a sustainable LCB supply chain is important. In this study, a multi-objective optimization model integrated with high-resolution geographical data was developed to examine the optimal switchgrass supply chain for a potential biorefinery in Tennessee, specifically evaluating the potential tradeoffs between the objectives of minimizing plant-gate cost and GHG emissions from the switchgrass supply chain. The key findings of this study are as follows: both plant-gate feedstock cost and GHG emissions were sensitive to the type of land converted into switchgrass production ...

Switchgrass Capacity Procurement Contract And Tonnage Contract Pricing, Tianpeng Zhou

Masters Theses

The on-farm production of switchgrass has been given considerable attention by farmers, policymakers and others. However, because the switchgrass market is not developed yet, most of the research only focuses on the switchgrass breakeven cost. The appropriate price combining interests of both the biorefinery and the farmers, or the contract price, has not been given enough attention.

Two types of contractual relationships are discussed in this thesis: Capacity Procurement Contract (CPC, per acre contract) and Tonnage Contract (TC, per ton contract). The contract prices of switchgrass under these two types of contracts are estimated in this analysis. Because the land ...
