Assessing Natural Resources Conservation Service (Nrcs) Impacts On Rice And Soybean Efficiency In The Mid-South, Ayodeji Samuel Ayiti

LSU Master's Theses

The study investigates how the Mid-South region of the U.S. rice and irrigated soybean production efficiency is influenced by (NRCS) incentives. To evaluate the effect of crop insurance, subsidies, and conservation incentives on lowering inefficiency, this study used a stochastic frontier model (SFA). The dataset covered the years 2010 – 2023, which allowed for a thorough evaluation of efficiency trends over time. While crop insurance programs reduce inefficiency in rice production, it shockingly increases inefficiency in soybean production, according to the study, which highlights the disparate effects of net support (insurance-subsidy).

The results show that while external factors like changes …

A Comparison Of Diploid And Triploid Eastern Oysters For Aquaculture Production Under Extreme Temperatures And Salinities, Joshua H. Kim

LSU Master's Theses

Off-bottom aquaculture of Eastern oysters (Crassostrea virginica) is a nascent industry that is increasingly supported by the use of triploid oysters, which grow faster than diploids. Despite their growth advantage, elevated triploid mortality compared to diploids under high temperature, low salinity, or a combination of these conditions challenge consistent triploid production. Identifying the environmental thresholds at which differential triploid mortality occurs and predicting its economic impact are important to informing decision-making in oyster aquaculture. The goal of this thesis was to compare the biological and economic performance of diploid and triploid oysters under high temperature and low salinity conditions. …

The Impact Of Xenophobia On Agricultural Trade In South Africa, Maxwell Peprah Amponsem

LSU Master's Theses

The growing number of farm attacks and xenophobia is one of the most serious crime issues facing the South African government. This study examines the impact of xenophobia on agricultural trade, using port-level trade data and xenophobia incident records from 2010 to 2023. Utilizing fixed effects Ordinary Least Squares (OLS) specifications, I find a significant negative impact of xenophobia on agricultural exports, while non-agricultural trade remains unaffected. These findings highlight the need for targeted policy interventions to combat xenophobic violence and stabilize the agricultural sector, ensuring the continuity of South Africa's trade and economic growth.

Variability In Rice Returns Using A Representative Farm Approach, Adriana Dimas

LSU Master's Theses

Agriculture is a major contributor to the U.S. economy and vital to the continued availability of a safe and inexpensive food supply. Representative farms are virtual farms that represent the production practices of a specific crop and region. Annually, growers face critical management decisions on what crop enterprise selection and combinations will maximize the net returns. Risk for growers comes from the variation in different factors such as yield, market price, production input costs, among others that are required to produce each enterprise. Nine representative farms were established within Louisiana, Mississippi, and Arkansas to evaluate net return variability among different …

Willingness Of Non-Industrial Private Forest Landowners To Obtain A Private Versus Public Consultation, Erika Largacha

LSU Master's Theses

Promoting conservation practices among family forests landowners play a critical role to enhance forest health and ecosystem services. Several certification programs recognize such efforts, but participation among landowners varies based on their characteristics, program requirements, and incentives. One crucial step of certification is to obtain a forest management plan, but acquisition among landowners remains extremely low. Several studies suggest connecting landowners with foresters as the key element towards the adoption of forest management plans. Because foresters are typically employed by public forestry agencies or as private self-employed consultants, landowners' willingness to work with either may differ. As far as we …

Coastal Louisiana is annually threatened by coastal storms. Population grown, wetland loss, and potentially increasing storm frequency are likely to increase coastal vulnerability to these events. Increasingly, coastal management entities are managing land resources to reduce the economic impact of natural disasters with the use of natural infrastructure. This is true in Louisiana where the Louisiana Coastal Master Plan allocates billions of dollars to coastal restoration projects, many of which are intended to mitigate economic damages from tropical storms and hurricanes. Despite this significant proposed investment, the risk reduction value provided by these projects is not well known. This analysis …

Private Market Alternatives For Maintaining Wetland Viability In Coastal Louisiana: A Double-Hurdle Approach, Hua Wang

LSU Doctoral Dissertations

The coastal zone of Louisiana contains more than three million wetland acres, or about 40 percent of the nation’s total. Since 1930, Louisiana has experienced a net loss of over 1,900 square miles of coastal wetlands. Currently at risk are the remaining coastal wetlands, 80 percent of which are under private ownership. The acceptance of private wetland owners to restoration programs and their participation in these programs are critical if future coastal restoration efforts are to be successful. Gaining the cooperation by the coastal landowners, however, is complicated by the fact that while the public benefits accruing from wetland protection …
