PPE Waste Disposal a Growing Pandemic Challenge

Read the full story at Specialty Pharmacy Continuum.

The increase in the need for personal protective equipment (PPE) and its use during the COVID-19 pandemic has produced a corresponding burden on the other end: a rise in medical waste as institutions dispose of gowns, gloves, masks, face shields and shoe covers that have been exposed to the virus. Are there different waste disposal requirements for COVID-19-contaminated PPE? How should your pharmacy and institution be handling this kind of waste?

Large companies like Netflix and Twitter have begun moving cash to Black-owned banks as a sign of support for racial equity. The economic benefits to Black communities of these moves is significant, and research shows consumers in general–and young people in particular–approve of companies that join the “justice deposits” movement. It’s a sign that in order to win over younger consumers, companies need to be attuned to social issues and act appropriately.

Agile Regulation for the Fourth Industrial Revolution: A Toolkit for Regulators

Download the document.

From autonomous vehicles to biotechnologies, technological breakthroughs across the digital, biological and physical spheres are heralding a Fourth Industrial Revolution. Governed well, these innovations can help power economic growth and address the world’s most pressing social and environmental challenges.

But regulation can struggle to keep pace with innovation, hindering the introduction of new ideas, products and business models, while leaving citizens with outdated protections. A more agile, flexible approach to regulation is needed in order to seize the potential of the Fourth Industrial Revolution to change lives for the better.

This guide provides regulators with a range of techniques they can employ to help respond in a more agile way to innovation and disruption. It demystifies what regulatory sandboxes, challenges and one-stop shops really are and explores the trade-offs between different regulatory strategies. It includes case studies from leading regulators on how to apply these techniques in practice and ideas on how to mainstream these approaches across the whole of government.

Biden administration to review contentious EPA landfill emissions regulation

Read the full story in Waste Dive.

The Biden administration will review the U.S. EPA’s contentious Emission Guidelines for Municipal Solid Waste Landfills (EG) regulation that has been stalled in legal battle for several years, a hint that the new administration may aim to speed the implementation process.

The 2016 regulation set forth emission guidelines for certain MSW landfills to limit greenhouse gas emissions, directing states to submit plans for complying with the emissions rules, and the EPA to create a federal plan to cover states that do not create their own. 

President Biden announced the review through an executive order on his first day in office, signaling his administration wants the EPA to put states “back on the clock for getting their rules done” and prompt the EPA to move forward with issuing its federal plan, said Pat Sullivan, senior vice president at SCS Engineers.

Illinois Poised to Provide a Climate Action Model for Other States

Read the full story at Climate XChange.

Amidst record-setting daily totals in COVID-19 cases and its largest spike in deaths since May, the state of Illinois opted to forgo its end of year legislative session. Citing health and safety concerns of state legislators and staff, Illinois House and Senate leadership cancelled the “veto session” – originally scheduled for November 17–19 and December 1–3. As a result, the attention of state lawmakers to push forward their legislative priorities has shifted toward January as the earliest that the General Assembly is expected to reconvene.

When the calendar flips to 2021, returning and newly-elected legislators will have a responsibility to address the state’s growing need for recovery assistance in light of the worsening pandemic. Bold action on climate in the form of the Clean Energy Jobs Act (CEJA) could play an important role in this. Illinois House and Senate Democrats, both of whom retained super-majorities in their respective chambers through November’s elections, are expected to waste no time in advancing an updated version of CEJA. The revised bill addresses concerns around utility accountability and equity while also providing a crucial model for other states aiming to take big action on climate.

Two-thirds of Earth’s land is on pace to lose water as the climate warms – that’s a problem for people, crops and forests

The world watched with a sense of dread in 2018 as Cape Town, South Africa, counted down the days until the city would run out of water. The region’s surface reservoirs were going dry amid its worst drought on record, and the public countdown was a plea for help.

By drastically cutting their water use, Cape Town residents and farmers were able to push back “Day Zero” until the rain came, but the close call showed just how precarious water security can be. California also faced severe water restrictions during its recent multiyear drought. And Mexico City is now facing water restrictions after a year with little rain.

There are growing concerns that many regions of the world will face water crises like these in the coming decades as rising temperatures exacerbate drought conditions.

Understanding the risks ahead requires looking at the entire landscape of terrestrial water storage – not just the rivers, but also the water stored in soils, groundwater, snowpack, forest canopies, wetlands, lakes and reservoirs.

We study changes in the terrestrial water cycle as engineers and hydrologists. In a new study published Jan. 11, we and a team of colleagues from universities and institutes around the world showed for the first time how climate change will likely affect water availability on land from all water storage sources over the course of this century.

We found that the sum of this terrestrial water storage is on pace to decline across two-thirds of the land on the planet. The worst impacts will be in areas of the Southern Hemisphere where water scarcity is already threatening food security and leading to human migration and conflict. Globally, one in 12 people could face extreme drought related to water storage every year by the end of this century, compared to an average of about one in 33 at the end of the 20th century.

These findings have implications for water availability, not only for human needs, but also for trees, plants and the sustainability of agriculture.

Where the risks are highest

The water that keeps land healthy, crops growing and human needs met comes from a variety of sources. Mountain snow and rainfall feed streams that affect community water supplies. Soil water content directly affects plant growth. Groundwater resources are crucial for both drinking water supplies and crop productivity in irrigated regions.

While studies often focus just on river flow as an indicator of water availability and drought, our study instead provides a holistic picture of the changes in total water available on land. That allows us to capture nuances, such as the ability of forests to draw water from deep groundwater sources during years when the upper soil levels are drier.

The declines we found in land water storage are especially alarming in the Amazon River basin, Australia, southern Africa, the Mediterranean region and parts of the United States. In these regions, precipitation is expected to decline sharply with climate change, and rising temperatures will increase evaporation. At the same time, some other regions will become wetter, a process already seen today.

Our findings for the Amazon basin add to the longstanding debate over the fate of the rainforest in a warmer world. Many studies using climate model projections have warned of widespread forest die-off in the future as less rainfall and warmer temperatures lead to higher heat and moisture stress combined with forest fires.

In an earlier study, we found that the deep-rooted rainforests may be more resilient to short-term drought than they appear because they can tap water stored in soils deeper in the ground that aren’t considered in typical climate model projections. However, our new findings, using multiple models, indicate that the declines in total water storage, including deep groundwater stores, may lead to more water shortages during dry seasons when trees need stored water the most and exacerbate future droughts. All weaken the resilience of the rainforests.

A new way of looking at drought

Our study also provides a new perspective on future droughts.

There are different kinds of droughts. Meteorological droughts are caused by lack of precipitation. Agricultural droughts are caused by lack of water in soils. Hydrological droughts involve lack of water in rivers and groundwater. We provided a new perspective on droughts by looking at the total water storage.

We found that moderate to severe droughts involving water storage would increase until the middle of the 21st century and then remain stable under future scenarios in which countries cut their emissions, but extreme to exceptional water storage droughts could continue to increase until the end of the century.

That would further threaten water availability in regions where water storage is projected to decline.

Changes driven by global warming

These declines in water storage and increases in future droughts are primarily driven by climate change, not land-water management activities such as irrigation and groundwater pumping. This became clear when we examined simulations of what the future would look like if climate conditions were unchanged from preindustrial times. Without the increase in greenhouse gas emissions, terrestrial water storage would remain generally stable in most regions.

If future increases in groundwater use for irrigation and other needs are also considered, the projected reduction in water storage and increase in drought could be even more severe.
