Farmer Perceptions Of Adopting Novel Legumes In Traditional Maize-Based Farming Systems In The Yucatan Peninsula, Jacques Fils Pierre, Luis Latournerie-Moreno, René Garruña-Hernández, Krista L. Jacobsen, Carrie A. M. Laboski, Lucila De Lourdes Salazar-Barrientos, Esaú Ruiz-Sánchez

Horticulture Faculty Publications

Intercropping constitutes the traditional farming system practice used in various forms for maize production in the Yucatan peninsula. Although practiced for centuries, problems persist with competition for water, nutrients and light between crop species in traditional farming systems. Furthermore, little is known about farmers’ perceptions regarding changes to traditional maize-legume intercropping systems and their interest in novel crop adoption to increase yields in the system while maintaining the practice. The objective of this study was to investigate the maize-based traditional cropping system by assessing the underlying motives and concepts of farmers to practice intercropping in the Yucatan Peninsula and to …

Fisheries Science Update - West Coast Demersal Scalefish Resource - October 2021, Department Of Primary Industries And Regional Development, Western Australia

Fisheries Science Updates

The West Coast Demersal Scalefish Resource (WCDSR) is halfway into a 20-year recovery plan following a period of overfishing in the 1990s and 2000s.

This latest assessment provides an important “health check” on the recovery status.

The recovery plan is based on maintaining recreational (including charter) and commercial sector’s total fishing mortality below catch limits and protecting key spawning aggregations to recover the WCDSR by 2030.

The Department of Primary Industries and Regional Development (DPIRD) tracks recovery progress by undertaking weight of evidence stock assessments of WCDSR indicator species dhufish and pink snapper every 3-5 years.

The latest science shows …

A Two-Stage Approach To Integrate Vessel Geo-Tracking Data And Logbooks For Monitoring Fishing Activity Of Coastal Fisheries In Waters Off Northwestern Taiwan, Yi-Jou Lee, Nan-Jay Su, Cheng-Hsin Liao, Wei-Chuan Chiang, Chun-Huei Li

Journal of Marine Science and Technology–Taiwan

Catch and fishing effort data are fundamental information to stock assessment and fisheries management, but difficult to obtain without the support of administration and sound fishery data collection system. This study integrated various sources of data from a simplified vessel geo-tracking system and logbooks from interviews with captains of coastal gillnet fisheries. We developed a two-step approach based on hierarchical cluster analysis to characterize the operation patterns and infer the fishing activities of the fishery. Results showed that the fishing effort in terms of operation duration could be estimated precisely for various vessel sizes, with catch composition and harvest information …

Population Structure Analysis Of The Endangered Oak Quercus Brandegeei, Carolyn Brinckwirth

DePaul Discoveries

As humans continue to impact landscapes and ecosystems throughout the entire world, many plant and animal species have faced major changes in their environments. The rare endemic oak, Quercus brandegeei, is one such endangered species located in the Sierra La Laguna mountains of Baja California Sur, Mexico. This tree occurs solely on the ephemeral riverbeds of the mountains, which are inundated seasonally by hurricane waters. It is important to understand the fundamental characteristics, like spatial distribution, of Q. brandegeei in order to develop restorative management practices to protect this tree against extinction. Determining the geographic distribution of a species …

Diminishing Opportunities For Sustainability Of Coastal Cities In The Anthropocene: A Review, John W. Day, Joel D. Gunn, Joseph Robert Burger

Biology Faculty Publications

The world is urbanizing most rapidly in tropical to sub-temperate areas and in coastal zones. Climate change along with other global change forcings will diminish the opportunities for sustainability of cities, especially in coastal areas in low-income countries. Climate forcings include global temperature and heatwave increases that are expanding the equatorial tropical belt, sea-level rise, an increase in the frequency of the most intense tropical cyclones, both increases and decreases in freshwater inputs to coastal zones, and increasingly severe extreme precipitation events, droughts, freshwater shortages, heat waves, and wildfires. Current climate impacts are already strongly influencing natural and human systems. …

Climate Adaptation And Water Conservation Decision-Making In Paso Robles, California Vineyards, Christopher R. Klier

Master's Theses

This paper examines vineyard perceptions and adoption of climate change adaptation and water conservation measures in the Paso Robles American Viticultural Area (AVA). A survey was distributed to all 220 vineyards and vineyard management companies that operate in the AVA, with a 53.64% response rate. The objective of the survey was to determine vineyard manager and owner attitudes towards climate change and adaptation, as well as their perceptions of how these threats would impact their operation. A second objective was to document the current level of water conservation and climate adaptation while identifying the barriers and opportunities for further adoption …

Degumming Of Hemp Fibers Using Combined Microwave Energy And Deep Eutectic Solvent, Bulbul Ahmed

LSU Master's Theses

Hemp is considered as one of the sustainable agricultural fiber materials. Degumming or surface modification of hemp bast is needed to produce single fibers for ensuing textile and industrial applications. The traditional degumming process necessitates a high amount of alkali, which causes detrimental environmental pollution. This study offers a new method to degum hemp fibers with reduced use of harmful alkali and precious water resources. In this work, hemp bast fibers were degummed by using combined microwave energy and deep eutectic solvent (DES). The properties of hemp fibers manufactured by this method were investigated and compared with the traditional alkali …

Net Geochemical Release Of Base Cations From 25 Forested Watersheds In The Catskill Region Of New York, Sara C. Nieman, Chris E. Johnson

Civil and Environmental Engineering - All Scholarship

Chemical weathering of minerals is the principal mechanism by which base cations (Ca²⁺, Mg²⁺, K⁺, and Na⁺) are released and acidity is neutralized in soils, bedrock and drainage waters. Quantifying the release of base cations from watershed soils is therefore crucial for the calculation of “critical loads” of atmospheric acidity to forest ecosystems. We used a mass-balance approach to estimate the rate of release of base cations in 25 headwater catchments in the Catskill region of New York, an area historically subject to high inputs of acid deposition. In 2010-2013, total net …

Effect Of Forage Management Strategies And Land Use Change On Nitrogen Budget And Soil Health Parameters In Pasture Systems, Yili Meng

LSU Doctoral Dissertations

Pastures produce hay for livestock, and they conserve soil, water, and air resources. However, high nitrogen (N) fertilizer demands in pasture production have significant implication on greenhouse gas emission and environmental pollution. Appropriate forage management strategies can reduce environmental N loss and improve soil health, to enhance the long-term pasture productivity. Therefore, this study was carried out to investigate the effects of management strategies on N budgets and soil health parameters in subtropical pastures. Both field and laboratory experiments were conducted to evaluate the effects of N stabilizers including urease inhibitor and nitrification inhibitor on pasture yield, greenhouse gas emission, …

Life Cycle Assessment Of Packaging Systems For Enteral Nutrition Products: Multilayer Pouch And High-Density Polyethylene Bottle, Martina Krueger, Benedikt Kauertz, Claudia Mayer

Journal of Applied Packaging Research

Environmental performance of alternative packaging options for a given product application increasingly comes into awareness, both at the end consumer level as well as in the field of business-to-business communication. The purpose of the study presented here is to examine the environmental performance of a multilayer pouch for packing of enteral nutrition products. To achieve this, a life cycle assessment has been conducted. As an attributional full cradle-to-grave life cycle assessment it compares environmental impacts of a comparable lighter multilayer pouch vs. two different comparable heavier high-density polyethylene bottles (covering the weight range of high-density polyethylene bottles on global markets …

The Applicability, Efficacy And Risks Of Natural Sequence Farming In The Dryland Agricultural Zone Of South West Western Australia, Nik Callow, Rose Anne Bell

Natural resources commissioned reports

Natural sequence farming (NSF) is an approach to restoring degraded agricultural land, developed by Peter Andrews on his property Tarwyn Park in New South Wales. The approach aims to rehydrate the landscape by slowing the movement of water with a series of structures and then using this water to drive plant growth and improve soil function.

The Department of Primary Industries and Regional Development engaged the University of Western Australia to review the applicability, efficacy and risks associated with using NSF principles and practices in the south-west dryland agricultural zone in Western Australia. The review has combined information from the …

Fractured Rock Groundwater Wa Wheatbelt: Data And Methodology Review, Louise Hopgood, Richard Nixon

Natural resources commissioned reports

The Department of Primary Industries and Regional Development (DPIRD) in partnership with Water Corporation, working with Murdoch and Curtin universities, are looking at new options to improve farm water security in the wheatbelt of Western Australia.

Winter rainfall has declined since 2000 and dams, traditionally used for farm water supply, no longer provide sufficient or reliable water, especially after 1 to 2 below average years. Increasingly, groundwater supplies are being considered to supply farm needs, including those from fractured rock aquifers, with opportunities to desalinate to improve water quality.

This project undertook to review groundwater availability in fractured rock aquifers …

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob

Sustainability and Social Justice

As one of the most densely populated regions on the continent of Africa, the Albertine Rift (consisting of parts of Rwanda, Uganda, and the eastern DRC) faces ongoing problems providing enough food for its people through crop production, livestock husbandry, and other forms of food production. Even more troubling for the future is that anthropogenic climate change is expected to significantly exacerbate food insecurity. This paper addresses one central question: how will climate change impact food security in the Albertine Rift? Based on an analysis of available data, this paper finds that policymakers should listen closely to local farmers and …
