The Effect Of Climate Change On The Economics Of Conservation Tillage: A Study Based On Field Experiments In Indiana, Whitney Hodde

Open Access Theses

This study evaluates the economics of conservation tillage (chisel till and no till) and examines how climate change will likely affect it. We use data from long-term experimental plots in Indiana to estimate how corn and soybean yields respond to weather patterns under alternative tillage practices. Yield functions are coupled with random draws of weather variables to construct distributions describing the probability that conservation tillage will result in higher profits than more intensive tillage, under current and future climatic regimes. Results suggest that, in our study area, projected climate change will make conservation tillage more attractive.

Irrigation Adoption, Groundwater Demand And Policy In The U.S. Corn Belt, 2040-2070, Molly A. Van Dop

Open Access Theses

Climate change across the U.S. Corn Belt will significantly increase precipitation variability and temperatures by midcentury. Corn and soybean producers will seek to find strategies that may help to mitigate the potentially negative effects on yield. The adoption of irrigation technology has increased over the last several decades to improve yields in areas with insufficient rainfall, and is currently being adopted by producers who are choosing to minimize risk due to weather variability. To see if this trend in irrigation adoption has the potential to expand in the wake of climate change, this study uses weather data from four General …

The Impact Of Climate Change In Bangladesh On The Rice Market And Farm Households, Mst Ashrafun Nahar

Graduate Theses and Dissertations

Bangladesh is trying to achieve self-sufficiency in domestic rice production but climate change effects on agricultural production makes it challenging to attain the goal. The country is highly vulnerable to the effects of climate change since it is the major cause to rise in sea level, more warm summer, and happening food and cyclone in the country.

This study develops an Aggregate Farm Household Model to analyze the impact of potential land loss and yield reduction from climate change on production, consumption, prices, welfare, and the ability of government to achieve self-sufficiency in rice production. The model is calibrated to …

A Systems Approach To Modelling The Effects Of Climate Change On Agroforestry: A Case Study In Western Tanzania, Elaine M. Samuel

Electronic Thesis and Dissertation Repository

Climate change is anticipated to have significant effects on agricultural production in sub-Saharan Africa as the magnitude of weather events increase in severity. Smallholder farmers in western Tanzania are potentially vulnerable to climate change impact as crops rely on precipitation as the only source of water. It is prudent to evaluate different modes of agricultural adaptations, such as agroforestry, that these farmers can easily adopt to improve their resiliency to the effects of climate change. System dynamics modelling is a cost-effective tool to simulate the long-term behaviour of agroforestry systems under future climate conditions. Water, Nutrient, and Light Capture in …

Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali

Theses

The stratospheric ozone depletion and elevated solar UV-B radiation have a negative effect on living life forms. UV radiation is one of the unsafe components that cause hindrance to both flora and fauna on the earth. This will have important implications for ecosystem processes and food production. The present study has been designed with primary objective of the effect of UV-B radiation on five numbers of most cultivated Emirates varieties (i.e., BARHI, FRDWT, NBTSF, FRDRD and KHD). After 4 and 8 hrs/day UVB treatment the Shoot, Root and total Plant length, Total plant fresh weight, Shoot and Root fresh and …
