San Diego Regional Quality of Life Dashboard
As the need for Green Workforce jobs rises, it is essential that companies are transparent about pay. The California Pay Transparency Law (SB 1162) enforces job descriptions that explicitly outline employee compensation, which is also a step towards closing gender and race-based pay gaps. It also prohibits employers from using hiring practices that may be discriminatory against certain groups of people. SB 1162 builds honesty, trust, and equity in the workplace for job seekers today and for generations to come.

Genetic Modification – Applications For Forage And Grassland Production Systems, J. R. Caradus
IGC Proceedings (1997-2023)
Genetic modification has been extensively used in crops for 25 years but has rarely been a technology used to advance trait expression in forage and grassland species. The exceptions are the use of herbicide tolerance and low lignin traits in alfalfa which are currently commercially available. In crop species genetic modification has been a valuable option for delivering improved economic and environmental outcomes through providing solutions for many of the challenges facing mankind. There are a many beneficial characteristics that genetic modification has the potential to provide in forage and grassland species. Managing these in the environment and understanding consumer …

Environmental Co-Benefits Of Improved Forages In Smallholder Dairy Systems Of Kenya, A. Notenbaert, S. Mwendia, S. Burkart, P. Karimi, E. Mwema
IGC Proceedings (1997-2023)
Livestock play a major role across Kenya, especially in smallholder mixed farms through provision of household nutrition and income through milk and meat. Equally, fertilization of cropland benefits from livestock manure, and livestock often act as insurance and saving. Despite the opportunities and benefits livestock production presents, livestock systems are also key drivers of environmental degradation, including increased nutrient loads, GHG emissions, water use, grassland degradation and land-use conversion. Low livestock productivity, largely due to use of low-quality crop residues and natural grasses often not endowed with nutrients key for animal performance, limits the potential positive contributions of livestock and …

Raising Student Awareness Of Environmental Issues Via Writing Assignments With Differential Equations, Michelle L. Ghrist
CODEE Journal
In this paper, I discuss two environmentally-focused writing assignments that I developed and implemented in recent integral calculus and differential equations courses. These models of carbon storage and PCB’s in a river provide interesting applications of one-compartment mixing problems. The assignments were intended to focus student attention on sustainability concerns while also developing other essential skills. I discuss these assignments and their effect on my students’ technical writing and environmental awareness. Detailed introductory instructions and mostly complete solutions to these assignments appear in the appendices, to include sample student work.

Vegetated Coastal Ecosystems In The Southwestern Atlantic Ocean Are An Unexploited Opportunity For Climate Change Mitigation, Vanessa Hatje, Margareth Copertino, Vinicius F. Patire, Ximena Ovando, Josiah Ogbuka, Beverly J. Johnson, Hilary Kennedy, Pere Masque, Joel C. Creed
Research outputs 2022 to 2026
Vegetated coastal ecosystems (mangroves, seagrasses, and saltmarshes, often called Blue Carbon ecosystems) store large carbon stocks. However, their regional carbon inventories, sequestration rates, and potential as natural climate change mitigation strategies are poorly constrained. Here, we systematically review organic carbon storage and accumulation rates in vegetated coastal ecosystems across the Central and Southwestern Atlantic, extending from Guyana (08.28°N) to Argentina (55.14°S). We estimate that 0.4 Pg organic carbon is stored in the region, which is approximately 2-5% of global carbon stores in coastal vegetated systems, and that they accumulate 0.5 to 3.9 Tg carbon annually. By ecosystem type, mangroves have …

IGC Proceedings (1997-2023)
Silvopasture is a sustainable land use management practiced in most continents in the world including parts of southern Europe, but is not broadly used in northern and western Europe. The importance of this practice has been recognised and the last draft of the EU regulation by the European Agricultural Fund for Rural Development (http://europa.eu.int/comm/agriculture/capreform/rurdevprop_en.pdf) includes specifically funding for establishment of agroforestry practices in Europe. This paper discusses the advantages of managing semi intensive grassland within a silvopastoral system from an ecological, productive and social point of view in the south, south-central and western countries of Europe.

Evaluating The Economic And Environmental Sustainability Of Integrated Farming Systems, C. A. Rotz, M. A. Sanderson, M. Wachendorf, F. Taube
IGC Proceedings (1997-2023)
Economic and environmental sustainability has become a major concern for forage-based animal production in Europe, North America and other parts of the world. Development of more sustainable farming systems requires an assimilation of experimental and modelling research. Field research is critical for supporting the development and evaluation of models, and modelling is needed to integrate farm components for predicting the long-term effects and interactions resulting from farm management changes. Experimentally supported simulation provides a tool for evaluating and comparing farming strategies and predicting their effect on the watershed, region and beyond.

All living organisms acclimate to their environments, with ectothermic species particularly susceptible to environmental change, specifically temperature. Ectothermic insects like crickets directly alter their physiological processes depending on the environment in which they live. Temperature is vital in regulating processes such as metabolism, respiration, and reproduction, among other things. What remains unclear is how a change in the environment, specifically extreme temperature change and dietary alterations, affects physiological processes. In this study, we performed experiments on ectothermic banded crickets to examine the effects of temperature change and the interaction of temperature and diet on oxygen consumption. For both experiments, we …
