An aid to ecological management and decision-making ES supply and demand dynamics
2023-08-19
(Press-News.org)
Ecosystem services (ESs) provide a variety of services and benefits for human well-being, but the supply-demand mechanism of ecosystem services under different spatio-temporal scales is unclear. The Taihu Lake Basin (TLB) is a microcosm of degraded and unsustainable ecosystem services. Rapid industrialization and urbanization poses a great threat to the environment and ecology. Therefore, it is urgent to assess the changes in supply and demand for TLB ecosystem services from a spatio-temporal and multi-stakeholder perspective, and this will be conducive to the scientific and sustainable development of ecological services.
Circular Agricultural Systems published an online paper entitled “Quantifying the difference between supply and demand of ecosystem services at different spatial-temporal scales: A case study of the Taihu Lake Basin” on 31 May 2023.
In this study, the InVEST model was used to quantify the dynamics of ESs supply and demand in the TLB from 2010-2020, as well as to compare the mismatch between supply and demand for five ESs (i.e., water yield, carbon sequestration, recreation, food production, and heat regulation services) at four spatial scales (pixel scale, township scale, county scale, and city scale). The study highlights the increasing quantitative and spatial differences in the supply and demand of environmental services in the TLB, in particular the conflict between carbon sequestration services and heat regulation services, which has become a major constraint to the development of environmental services. At the same time, there is a certain demand gap for water yield services and food production services. Evaluations of ecosystem service deficit and redundancy (ESDR) indicated that significant deficits are mainly in densely populated towns of the eastern and central regions, while high surplus areas are mainly in the forested areas in the southwest. Comprehensive ecosystem service deficit and redundancy (CESDR) metrics showed a decline from -0.03 in 2010 to -0.05 in 2020, among which urban areas like Shanghai and Suzhou reflect pronounced imbalances. The data underscores the urgency for focused policy interventions in regions with high deficit.
In conclusion, this study analyzes the quantitative characteristics and spatial-temporal pattern of the relationship between the supply and demand of ESs in TLB at different scales. It emphasizes that a multi-scale analytical approach should be adopted in policy formulation to achieve a balance between supply and demand through reasonable ecological protection and ecological restoration . It also strengthens the analysis of ES flows and stakeholders. Multi-regional and multi-scale linkages harmonize the carrying capacity of resources and the environment with the level of development in the region.

Medical students who reported a disability to their school increased by more than 25% during the COVID-19 pandemic, a study shows.
The proportion of students reporting attention deficit hyperactivity disorder or chronic health and/or psychological disabilities has increased between 2015 and 2021.
Despite the increase in medical students reporting these conditions, the requests for more inclusive preclinical testing accommodations, like extra time for test completion or a less distracting environment, decreased during the pandemic between 2019 and 2021.
According to authors of the new research letter in JAMA Network Open, the remote curriculum delivery during the pandemic may have allowed ...

The U.S. Department of Energy has awarded an LSU-led consortium a $4.9 million grant to support the first phase of the Pelican Gulf Coast Carbon Removal project. The Pelican Consortium, which includes Shell and the University of Houston, will evaluate the feasibility of building a direct air capture (DAC) hub in Louisiana. DAC technologies capture carbon dioxide directly from the atmosphere. The captured carbon dioxide can then be used to manufacture products or be permanently stored in deep geological formations.
The project will leverage existing regional infrastructure in one of the highest emitting areas in the Gulf Coast, benefit the local energy workforce, and support ...

WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today announced $70 million in funding to support research by historically underrepresented groups in science, technology, engineering, and mathematics (STEM) and to diversify leadership in the physical sciences. The funding, through DOE’s Reaching a New Energy Sciences Workforce (RENEW) initiative, will support internships, training programs, and mentor opportunities at 65 different institutions, including 40 higher-learning institutions that serve minority populations. Ensuring America’s best and brightest students have pathways to STEM fields will be key to leading the world’s energy transition ...

Findings from a two-year study of nearly 2,400 solid organ transplant recipients, conducted by the Johns Hopkins Transplant Research Center (TRC) in collaboration with the New York University Center for Surgical and Applied Transplant Research, indicate spikes of post-vaccination SARS-CoV-2 viral infections (commonly known as COVID-19 breakthrough cases) remain common, yet hospitalization rates have dramatically dropped following the first wave of the virus’ omicron subvariant.
“These results mirrored ...

NEW ORLEANS, LOUISIANA — Tulane University, Ochsner Health and the community nonprofit RH Impact have been awarded a seven-year, $16.5 million grant from the National Institutes of Health to establish a research center of excellence focused on finding solutions to address Louisiana’s disproportionately high maternal mortality rate.
The new Southern Center for Maternal Health Equity will be one of 10 newly announced Maternal Health Research Centers of Excellence nationwide funded by the NIH’s Implementing a Maternal health and PRegnancy Outcomes Vision for Everyone (IMPROVE) initiative.
The center will develop and evaluate innovative approaches to reduce pregnancy-related ...

E-cigarettes do have value as a smoking cessation aid, according to a new study just released by a team of MUSC Hollings Cancer Center researchers.
Whether e-cigarettes should be considered for smoking cessation is a hotly debated topic, and different countries have taken different approaches. E-cigarettes contain harmful chemicals, which has led many public health advocates to shun them. But they are less harmful than traditional cigarettes, which can cause a dozen types of cancer as well as heart disease, stroke, diabetes and chronic obstructive ...

LA JOLLA, CA—According to new research in the journal Immunity, T cells have a nuclear receptor doing something very odd—but very important—to help them fight pathogens and destroy cancer cells. This receptor, called retinoic acid receptor alpha (RARα), is known to control gene expression programs in the nucleus, but it also now appears to operate outside the cell nucleus to coordinate the early events triggered at the cell surface that lead to T cell activation.
Scientists wouldn’t normally expect to see a nuclear receptor ...

Organisms across the globe are facing unprecedented levels of stress from climate change, habitat destruction, and many other human-driven changes to the environment. Predicting and mitigating the effects of this increasing stress on organisms, and the environmental services on which we depend, requires understanding why some species can exist in a wide range of environments while others exist in only a few habitats.
In the scientific world of ecology, researchers often try to sort organisms on our planet into two categories: specialists and generalists. Generalists can survive across a wide variety of environmental conditions and habitats, while specialists ...

BOSTON– A team led by researchers from Mass Eye and Ear, a member of Mass General Brigham, reports the results of a phase I trial of a revolutionary stem cell treatment called cultivated autologous limbal epithelial cell transplantation (CALEC), which was found to be safe and well-tolerated over the short term in four patients with significant chemical burns in one eye. According to the study published August 18 in Science Advances, the patients who were followed for 12 months experienced restored cornea surfaces — two were able to undergo a corneal transplant and two reported significant improvements in vision without additional treatment.
