Improving The Land Trust Model’S Impact On Environmental Conservation In Northern California, Peter Talbot 2023 University of San Francisco

Improving The Land Trust Model’S Impact On Environmental Conservation In Northern California, Peter Talbot

Master's Projects and Capstones

For years, the land trust sector of California and much of the United States has operated with a dollars and acres mentality that has prioritized fundraising as a result of acreage protected. Within California, nearly 5.8 million acres of land have been protected by 132 land trusts throughout the state. To accommodate for the diverse cross-section of land and the many needs of the population, land trusts take on numerous shapes and sizes. A unique aspect of this diversity is the rich agricultural and natural spaces found throughout the state. This mix of land and variety of land uses has …

Nutrient Optimization For Vegetable Production Under Decoupled Aquaponics Using Brackish Water, Salma Walid Hany Ahmed Abdelfattah

Theses and Dissertations

As the world moves to more sustainable agriculture methods in the agribusiness industry, decoupled aquaponics is recognized as one of the newest techniques currently being utilized to achieve more local food security. As the topic is still freshly new within the industry, a finite number of publications and studies have been made that address the topic hands-on with its many variables. Subsequently, in this paper, an experiment was conducted to assess the most optimized production conditions of both lacinato kale (Brassica oleracea var.palmifolia) and Swiss chard Bright Light (Beta vulgaris ssp. Cicla var. flavescens) plants through the utilization of a …


Why Agriculture Productivity Falls: The Political Economy Of Agrarian Transition In Developing Countries, Rashed Al Mahmud Titumir 2023 University of Dhaka, Bangladesh

Why Agriculture Productivity Falls: The Political Economy Of Agrarian Transition In Developing Countries, Rashed Al Mahmud Titumir

Purdue University Press Books

Why Agriculture Productivity Falls: The Political Economy of Agrarian Transition in Developing Countries offers a new explanation for the decline in agricultural productivity in developing countries. Transcending the conventional approaches to understanding productivity using agricultural inputs and factors of production, this work brings in the role of formal and informal institutions that govern transactions, property rights, and accumulation. This more robust methodology leads to a comprehensive, well-balanced lens to perceive agrarian transition in developing countries. It argues that the existing process of accumulation has resulted in nonsustainable agriculture because of market failures—the result of asymmetries of power, diseconomies of scale, …

The Changing Cost Of Cattle Transportation, Elliott James Dennis 2023 University of Nebraska - Lincoln

The Changing Cost Of Cattle Transportation, Elliott James Dennis

Center for Agricultural Profitability

Diesel is one of the primary inputs in the transportation of goods throughout the United States. Livestock hauling is no exception. Feeder cattle are generally transported long distances in the fall as they move from summer grazing to placement in backgrounding operations or directly into feedlots. Cattle, and other livestock in general, can handle transportation stress fairly well – to a point. Trucking feeder cattle long distances can impact animal health outcomes, and improper animal handling can lead to bruised or injured cattle. These negative impacts can generally be offset by appropriate stocking densities, proper trailer ventilation, correct animal handling …

Intensification, the process of intensifying land management to enhance agricultural goods, results in “intensive” pastures that are planted with productive grasses and fertilized. These intensive pastures provide essential ecosystem services, including forage production for livestock. Understanding the synergies and tradeoffs of pasture intensification on the delivery of services across climatic regions is crucial to shape policies and incentives for better management of natural resources. Here, we investigated how grassland intensification affects key components of provisioning (forage productivity and quality), supporting (plant diversity) and regulating services (CO2 and CH4 fluxes) by comparing these services between intensive versus extensive pastures in subtropical …

Simulated Temperatures Of Forest Fires Affect Water Solubility In Soil And Litter, Konrad Miotliński, Kuenzang Tshering, Mary C. Boyce, David Blake, Pierre Horwitz

Research outputs 2022 to 2026

As wildfires are of increasing concern in a warming world, there is a need to understand how fire temperatures affect solute concentrations of forest litter and soils in drinking water catchments. In addition, the concentrations are expected to be affected by time since the previous fire. We sampled soil and litter from recently (2 months) and less recently (4.5 years) burnt sites from jarrah forest in SW Australia. The samples were heated at 250°C, 350°C, and 500°C for 30min followed by leaching to determine solute compositions at these temperatures and in unburnt samples. At 250°C–350°C, we found increased concentrations of …


Understanding Irrigation Water Optimization, Burdette Barker, Matt Yost, Jody Gale, Mark Nelson 2023 Utah State University

Understanding Irrigation Water Optimization, Burdette Barker, Matt Yost, Jody Gale, Mark Nelson

All Current Publications

Irrigation is applied to much of the cropped area of Utah to support crop production. Limited water resources and competing demand for those resources make irrigation water conservation, irrigation water optimization, and efficient use of irrigation water important components of overall water resource management. It is well known in Utah that optimal irrigation use is even more critical during drought conditions. However, optimization practices change the quantity, quality, and timing of water flows. It is important to consider the possible hydrologic impact of irrigation practice changes and the desired outcome of an optimization practice to avoid implementing a practice that …

Managing Calf Market Risk With Lrp In 2023, Jay Parsons 2023 University of Nebraska-Lincoln

Managing Calf Market Risk With Lrp In 2023, Jay Parsons

Center for Agricultural Profitability

When profit margins are strong, livestock owners have a natural tendency to relax a bit and enjoy the business of producing animals. Expansion may come to mind and effort is often put forth to improve production output. Protecting market price may become a secondary priority. However, a lot can happen between now and marketing time. Price trends can suddenly turn and quite often expectations may not be met. Protecting price should be just as much — maybe more — of a priority when the price outlook is optimistic, as it is in a downward trend. An unprotected, overly optimistic price …

Higher Cattle Prices Are Good But Wide Profit Margins Are Better, Elliott Dennis 2023 University of Nebraska-Lincoln

Higher Cattle Prices Are Good But Wide Profit Margins Are Better, Elliott Dennis

Center for Agricultural Profitability

Feeder and fed cattle prices have continued to rise throughout the first part of the year. Reduced cattle supplies and relatively stable beef demand have helped support higher prices. Fed and feeder cattle prices have reached all-time heights, at least nominally. In low inflationary environments comparing nominal prices across time would be less problematic. Contrary to previous sentiments, inflation has not been transitory. Inflation, as measured by the Personal Consumption Expenditures Excluding Food and Energy (Chain-Type Price Index), has increased significantly in the last 3 years (see Figure 1) and thus comparison across years should be done using real prices …
