Environmental Analysis Of Codfish Production And Consumption In Portugal, Ayla Frost, Joana Almeida, Joana Dionisio, Radu Godina, Cátia Magro Feb 2024

Environmental Analysis Of Codfish Production And Consumption In Portugal, Ayla Frost, Joana Almeida, Joana Dionisio, Radu Godina, Cátia Magro

Journal of Critical Global Issues

Codfish, a typical dish consumed frequently in Portugal, is fished in the cold Northern Atlantic waters far from the Portuguese coast. Thus, regional tensions and the environmental impacts of Portuguese codfish importation and production are significant current issues. The present study uses a life cycle assessment methodology to evaluate the array of environmental impacts of the production of 1 kg of codfish, following a cradle to gate approach. The life cycle inventory was grouped into catch and preprocessing, transit, and curing stages. The data collection of products and processes in each stage was based on scientific peer reviewed documents, technical …

Nanomaterials In The Environment, Human Exposure Pathway, And Health Effects: A Review, Arindam Malakar, Sushil R. Kanel, Chittaranjan Ray, Daniel D. Snow, Mallikarjuna N. Nadagouda

Daugherty Water for Food Global Institute: Faculty Publications

Nanomaterials (NMs), both natural and synthetic, are produced, transformed, and exported into our environment daily. Natural NMs annual flux to the environment is around 97% of the total and is significantly higher than synthetic NMs. However, synthetic NMs are considered to have a detrimental effect on the environment. The extensive usage of synthetic NMs in different fields, including chemical, engineering, electronics, and medicine, makes them susceptible to be discharged into the atmosphere, various water sources, soil, and landfill waste. As ever-larger quantities of NMs end up in our environment and start interacting with the biota, it is crucial to understand …


Optimizing The Environmental And Economic Sustainability Of Contingency Base Infrastructure, Jamie E. Filer Mar 2020

Optimizing The Environmental And Economic Sustainability Of Contingency Base Infrastructure, Jamie E. Filer

Theses and Dissertations

Contingency bases are often located in remote areas with limited access to established infrastructure grids. This isolation leads to standalone systems comprised of inefficient, resource-dependent infrastructure, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. Planners can mitigate these negative impacts by selecting sustainable technologies. However, such alternatives often come at a higher procurement cost and mobilization requirement. Accordingly, this study aims to develop and implement a novel infrastructure sustainability assessment model capable of optimizing the tradeoffs between environmental and economic performance of infrastructure alternatives.

A Bycatch Action Plan For The Pilbara Fish Trawl Interim Managed Fishery., Department Of Fisheries Western Australia Jul 2010

A Bycatch Action Plan For The Pilbara Fish Trawl Interim Managed Fishery., Department Of Fisheries Western Australia

Fisheries management papers

The effect of commercial fishing on bycatch species and the marine ecosystem generally, has emerged as a significant national and international issue. Environmental issues associated with bycatch – including impacts on the ecology of non-target species of fish and wildlife – are important issues to address in reducing the impacts, or potential impacts, of commercial fisheries.

In 1998, the National Standing Committee on Fisheries and Aquaculture developed a national policy on fisheries bycatch. In 1999, the (then) State Minister for Fisheries adopted the national policy as his position on bycatch for Western Australia. The main objective of the policy is …

Fish Stock And Fishery Enhanceent In Western Australia. A Summary Report., Department Of Fisheries Mar 2004

Fish Stock And Fishery Enhanceent In Western Australia. A Summary Report., Department Of Fisheries

Fisheries management papers

This summary paper provides an overview of the key proposals set out in the full policy discussion paper, Fisheries Management Paper No 175. It does not discuss the theoretical background for the framework presented and therefore readers interested in such discussion are directed to Fisheries Management Paper No 175. Both papers have been prepared to encourage public involvement in the development of policy for stock enhancement within Western Australian waters. Stock enhancement can involve an existing fishery or creation of a new fishery through the translocation of fish. It affects both public and private waters.

Scott Coastal Plain A Strategy For A Sustainable Future, Department Of Agriculture And Food, Western Australia Jun 2001

Scott Coastal Plain A Strategy For A Sustainable Future, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

The Scott Coastal Plain has significant attributes that make it an area of State and regional significance for agricultural production. The climate, availability of good quality groundwater for irrigation, and large lot sizes provide opportunities for mechanised horticultural production which other parts of the State may not have.

An estimate of the area that could be used for each agricultural land use has been developed, at a broad study area level. The figures presented in this report show that diversified production combining tree plantation and/or irrigation (cropping or hay/silage) with grazing enterprises provides for potential increases in gross margins and …

Journal of the Department of Agriculture, Western Australia, Series 4

Sweet crunchy carrots, luscious strawberries at very reasonable prices, crisp green vegetables - these are just a few of the horticultural products that Western Australians take for granted and eat almost every day. But is their future availability guaranteed as population grows, suburbia spreads and environmental concern increases?


Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin Jan 1992

Red Kangaroos Can Set Back Range Regeneration, Andrew Mclaughlin

Journal of the Department of Agriculture, Western Australia, Series 4

After years of severe drought, stocking rates in Western Australia s arid rangelands have been kept low since the 1970s to allow native pastures to regenerate. As well, extensive re-seeding programs have started and sheep and cattle grazing on these areas has been restricted or eliminated. However, pasture regeneration in the rangelands can only succeed when grazing by all animals - sheep, cattle, kangaroos, goo.ts, camels, brumbies and donkeys - is controlled Many more red kangaroos roam throughout Western Australia's pastoral areas today than 20 years ago. The installation of windmills and troughs to water domestic livestock has allowed kangaroo …
