The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Fevered Planet: How a shifting climate is catalyzing infectious disease – The geography of disease is also changing as novel pathogens affecting plants, animals and humans increase their range. New beetles are heading north and devastating Siberian forests, Alaskan mammals are struggling as new ticks arrive and human habitations in northern Norway are infested by new insects.

‘Green Roads’ Are Plowing Ahead, Buffering Drought and Floods - Designing roads to capture water through strategic channels, culverts, and ponds and divert it for agricultural use. Nearly 20 countries have either implemented Green Roads for Water or plan to begin soon, and thousands of kilometers of roads, worldwide, have already received Green Roads interventions.

Photos of the year (2023) from the Prairie Ecologist (part 1 and part 2) – Lots of great nature photos.

How Fire-Prone Communities Can Reduce Their Risk - Playbook for the Pyrocene, which offers 20 community planning and design strategies that can be applied by landscape architects, planners, homeowners, and developers. “The questions we are trying to answer here are not so much where to build, but rather how to build better within the context of wildfire broadly.”

Giant Goldfish Are Bad News for the Great Lakes - In the Great Lakes, abandoned goldfish and their kin are known to root up plants, contribute to harmful algal blooms and consume native vegetation.

Nine breakthroughs for climate and nature in 2023 you may have missed – Yes – I missed some of these!

Parts of China’s Great Wall Are Protected by a ‘Living Cover’ of Biocrusts – Lichen, moss, and cyanobacteria!

Fresh water from thin air - Atmospheric water harvesting (AWH). The need for more affordable options has spurred interest in ‘passive’ AWH systems that use moisture-hungry sorbent compounds to collect water. The small amounts of power that such systems require could, ideally, be supplied by the Sun. Typically, these sorbents are exposed to the air overnight, when temperatures are cooler and moisture is more abundant. They collect the airborne moisture as liquid in a process known as adsorption. When day breaks, the sorbents are transferred to a device that uses solar energy to drive the release of water. This water is then condensed and collected. And there are abundant opportunities beyond simply producing drinking water. For example, a harvesting system that piggybacks on existing photovoltaic solar panels, using the waste heat and energy from these panels to power water production9; the resulting water helps to cool the panels and therefore improves their efficiency

Archaeologists Discover Brutal ‘Bakery-Prison’ at Pompeii - The cramped space provided minimal light, as windows to the outside were small, high and barred.

Thinking about Bridges

/

As I look at old books (on Internet Archive), the images of bridges always catch my attention. Why is that?

Perhaps I see them as a historical connection leading to social media of today….driven by our desire to communicate faster and to more people. Constructing bridges still helps us get from one place to another (usually over water); we do not think of the communication aspect of bridges so much anymore because there are so many other ways we can communicate; however, if there is a bridge destroyed by war or shut down by structural failure/renovation, we again become aware of how critical bridges are in our lives. Historically, as more durable bridges than a log across a stream were constructed…and longer bridges that could span a bay or connect islands to a continent…they must have resulted in cultural shifts locally. Were they as profound as the ones we experience now with social media? If so, the scale was smaller. Maybe there were some that realized the faster and broader communication is not always better…..that communication can foster division as well as consensus.

Or maybe they are symbols of our need to modify the world to meet our needs. We don’t always think through the impact of a bridge…the enabler it is to further development. For example, consider a bridge to a barrier island; that implies a road on the barrier island and then maybe beach houses or high-rise hotels with associated water and sewer infrastructure…dune and beach erosion, problems for structures when the island naturally wants to erode and rebuild.

Bridges are functional forms of art. They reflect the structural prowess of architects/engineers and the aesthetics of the culture and location where they are built.

Enjoy these pictures of bridges from some books I’ve browsed recently!

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Photographer Captures the Vast Beauty of Alaska Through Breathtaking Mountainscapes – Eventually I’d like to visit Alaska…but pictures are the next best way to experience the state.

Characteristics of older forests can buffer effects of climate change for some bird species – Results from an 8-year study (2011-18). Forests can provide refugia for some species….our stewardship is important.

Ruby was the first Black child to desegregate her school. This is what she learned – I’m glad she survived and thrived….don’t want any child going through this type of experience in the future. Education is challenging for child without accompanying trauma from the community or institution or bullies.

Should you feed garden birds? – Right now we have 2 bird feeders and baths…with a few plants in the yard that attract birds as well. Over the next few years, I will be planting for the birds – native plants that will support insects the birds need particularly during their breeding season…produce pollen and nectar and seeds to round out their diet.

Earth’s Iconic Waves, observed by Landsat – A 3.5 minute video about places on earth where the waves are significant enough to be visible from satellites…and a little about why those spots produce the types of waves observed.

The sands of Mars are green as well as red, rover Perseverance discovers – The discovery of volcanic rocks on Mars rich with large grains of olivine! I remember going to a green sand beach on the big island of Hawaii – olivine on earth.

Enhanced Geothermal Technology Cracks The 24/7 Energy Code – Maybe a technology that will be as important as wind and solar in our renewable energy portfolio.

What older adults do while they sit affects dementia risk – Passive behaviors like watching TV increased dementia risk-- on the plus side active behaviors while sitting like reading and using computers reduced dementia risk. The study had more than 145,000 participants aged 60 or over with nearly 12 years of follow-up.

Cataracts: we’re working on eye drops to treat them so people don’t need surgery – Glad the research is happening…probably not fast enough to be available when my cataracts will require treatment.

When Told About Flood Risk, Homebuyers Shun Vulnerable Homes, Study Finds – I shouldn’t be a surprise that people don’t want to buy properties that flood….and there are a lot of expensive coastal properties that have an increasing flood risk.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Can cloud seeding help quench thirst of the US West? – New research on an old idea…many states increase their use of the technology.

Fresh water from thin air – Another technology that might help dry regions….using hydrogels (like the ones currently used in diapers!).

What’s The Construction Industry Blueprint to Cut Carbon? – I wanted more specific examples…was a little disappointed that this article did not provide them, but maybe that would have made it a long article! I hope to see more on this topic.

Higher education must reinvent itself to meet the needs of the world today. Enter the distributed university – The pandemic has highlighted the challenges the current higher education model is facing. The ideas in this post are a start but don’t seem to be fully developed to push into full implementation. More work needs to be done to enable transition from the existing model to a new one that is more responsive to the needs not only of undergraduate students but for graduate students and continuing education. The sources of money in the current model don’t match up well. For example – in the US the sports programs (football) is a big money maker for many universities; how does that map into the new model (or do we want it to).

Upcycling plastic waste into more valuable materials could make recycling pay for itself – Hope this research can be transitioned into commercial use….we have to improve the recycling processes that are being used today. Too much is still ending up in landfills.

Fossil pollen reveals the African origins of Asia’s tropical forest – Research on Borneo’s Dipterocarps (very large trees with buttress roots, smooth/straight trunks, high crown) using fossil pollen reveals their origins in Africa…spread through India before it crashed into Asia…and then to Southeast Asia. The forests in India shrank as the climate became drier. These trees need a wet, seasonal climate to survive.

Mummification in Europe may be older than previously known – Analysis of bodies found in Mesolithic shell middens in Portugal reveal that they were probably mummified before being placed there 8,000 years ago. The description of the way the researchers came to that conclusion was interesting…a lot has been learned about forensics since the 1960s when the bodies were originally found. The oldest intentional mummification known before this finding was from the Chinchorro hunter-gatherers living in the coastal region of the Atacama Desert in shell middens (around 7,000 years old).

Lake Powell Reaches Lowest Level Since 1980s – The drought continuing in the west….

The myths and realities of modern friendship – Thought provoking. The ways we communicate with each have changed a lot over my lifetime!

The climate math of home heating electrification – The rationale for moving to heat pump heating/cooling as quickly as possible.

New Housing Development

2018 04 IMG_9872.jpg

I have lived in the same house for over 20 years and the area across the street from the neighborhood has always been a agricultural field.

2018 04 IMG_9873.jpg

There were some changes over the years: the field was planted with soybeans or corn or wheat – we always tried to observe the sprouts growing into seedlings as we went by to discover which it would be. The margins changed when herbicides came into popular use. Crop stubble was left, and tillage was reduced over the years – never leaving the soil bare for long or at all. And now – the process to develop the land into a residential neighborhood has started.

2018 04 IMG_9874.jpg

The development is in the initial phase with civil engineers doing studies and developing a sketch plan. Last week there was a ‘pre-submission community meeting’ (part of the county’s Development Review Process) that was crowded…people standing all around the edges of the room because the seats were full. It was my first experience at this kind of meeting and I was glad I got there early enough to get a seat. There was a lot of tension in the room with a lot of questions about the impact on already clogged roads and overcrowded schools. I am on the mailing list to get the responses to the issues raised within the next 30 days. I’m also sign up to the community Facebook page so that I can learn from others in the community that know more about how to maneuver within the process to protect the interest of the already existing neighborhoods…if this new development proceeds.

One of the new things I learned in the meeting was that the traffic issues on the roads now are largely due to a development that did not complete as planned and provide an entrance/exit to a major through street; instead the development only uses the narrow 2 lane roads in place prior to the development which were not designed for the volume of traffic they now carry. No wonder the people that have been following the issues for years are openly distrustful of the process and the developers rather than starting out in ‘trust but verify’ mode.

It’s positive that there are so many people engaged at this point…that the big issues have been surfaced. This is becoming my close-to-home HoLLIE-like project!
