The Day I always put off until absolutely necessary. It's me using the latest version of Adobe Photoshop and Lightroom. Why? Because they always always try to change enough basic tools and the options to "make it easier" which in this case means to more fully force Ai onto the process. Even though I DON’T WANT TO USE Ai. Arrgh, this simple edit to remove some dust shops and background distractions just took me about 1 1/2 hours. And worse yet, it is truly unclear if Adobe is not automatically converting the images you import into DNG, because I don't see that in any files. What I did find is that all the first images I applied the 2026 metadata I chose are all suddenly in .tif format (yay I selected that) BUT put them ALL into a new folder I DIDN'T EXPECT. And now they are all labeled with file names of .tif photos but the ONE file I exported as a trial run now was really really hard to find since ALL PHOTOS are now there, showing my Date Created as today, and all my original EXIF data, like ACTUAL DATE I created the photo is gone.

Anyway, just to increase my agony, here is a small vversion (for me, pixels 1200 x 900) and I've tried to reduce the photo sharpness to a lower percentage since I always edit photos full size, which is iPhone Pro Max 2998 or so by 3998 or so. Whatever. If this phioto is truly offensive to me as I now attempt to share on Ivory, don't be surprised if it goes poof! I hate hate hate all the Adobe Photoshop and Lightroom changes annually. And where the heck did my Camera Raw app go?

We’re here! One entrance line from ramp parking. Sooo many people from around the world. So many ages too! #Chalcedony #Specimen #Mineral #Crystals #Tucson #TucsonGemMineralShow

B̶u̶n̶c̶h̶ ̶o̶f̶ ̶g̶r̶a̶p̶e̶s̶

Ah, another grape chalcedony specimen! I’m celebrating because in half an hour we are setting off on another rockin’ day adventure. To the world’s largest gem and mineral show, Tucson.

This is the first convention center showcase I’ve been to in about 6 years. And when I saw “we”, my son John agreed to come which means Drew gets to come too, with his wheelchair. So, a family adventure today, our “day-cation” 118 miles south. To do this, we have to have both I and John push Drew and wangle the 3 of us around thousands of people in the enormous center. We leave very early in hopes we can score accessible parking. This is EPIC!

Indigenous Empowerment to Reverse Amazonia’s Mineral Demand

Illegal #mining for minerals like #gold and cassiterite, the latter used for renewable energy, is driving #deforestation in Indigenous #Amazonia. Countries like #Brazil, #Suriname and #Guyana face the challenge of conserving forests, protecting #indigenous peoples, biodiversity whilst also meeting international resource demands. Empowering indigenous peoples to care for biodiversity rich areas of Amazonia is key to saving them for future generations. Act now to protect Indigenous lands and wildlife. #BoycottGold4Yanomami #Boycott4Wildlife.

Illegal mining for critical minerals needed for the global renewable energy transition is increasingly driving deforestation in Indigenous lands in the Amazon.

In recent years, these illegal miners, who are often self-employed, mobile and working covertly, have expanded their gold mining operations to include cassiterite or “black gold”, a critical mineral essential for the renewable energy transition. Cassiterite is used to make coatings for solar panels, wind turbines and other electronic devices. Brazil, one of the world’s largest exporters of this mineral, is now scrambling to manage this new threat to its Amazon forests.

The need for developing countries such as Brazil to conserve their forests for the collective global good conflicts with the increasing demand for their resources from international markets. To complicate matters further, both the renewable energy transition and the conservation of the Amazon are urgent priorities in the global effort to arrest climate change.

But escalating deforestation puts these forests at risk of moving from a carbon sink – with trees absorbing more carbon dioxide from the atmosphere than they release – to a carbon source, whereby trees release more carbon dioxide than they absorb as they degrade or are burnt.

Indigenous and other forest-dwelling communities are central to forest conservation. In 2014, I spent a year living in Guyana and Suriname, two of the nine countries that share the Amazon basin. I studied the effectiveness of international policies that aim to pay these countries to avoid deforestation.

I met with members of communities who were bearing the brunt of the negative effects of small-scale gold mining, such as mercury poisoning and loss of hunting grounds. For decades, mining for gold, which threatens communities’ food supply and traditional ways of life, has been the main driver of deforestation in both countries.

Small-scale mining operations can damage both communities and the natural world. Gold mining, which generates gold for export used for jewellery and electronics, usually begins with the removal of trees and vegetation from the topsoil, facilitated by mechanical equipment such as excavators. Next, the miners dig up sediment, which gets washed with water to extract any loose flecks of gold.

Miners usually then add mercury, a substance that’s known to be toxic and incredibly damaging to human health, to washing pans to bind the gold together and separate it from the sediment. They then burn the mercury away, using lighters and welding gear. During this process, mercury is inhaled by miners and washed into nearby waterways, where it can enter the food chain and poison fish and other species, including humans.

My new book, Forests of Refuge: Decolonizing Environmental Governance in the Amazonian Guiana Shield, highlights the colonial histories through which these countries were created. These histories continue to inform the land-use practices of people and forest users there. Having seen the dynamics firsthand, I argue that these unaddressed histories limit the effectiveness of international policies aimed at reducing deforestation.

Some of the policies’ limitations are rooted in their inattentiveness to the roughly five centuries of colonialism through which these countries were formed. These histories had seen forests act as places of refuge and resistance for Indigenous and Afro-descendant communities. I believe that power structures created by these histories need to be tackled through processes of decolonisation, which includes removing markets from their central place in processes of valuing nature, and taking seriously the worldviews of Indigenous and other forest-dependent communities.

But since 2014, small-scale mining-led deforestation in the Amazon has persisted, and even increased. The increase in mining worldwide, driven partly by the renewable energy transition, indicates that these power structures might be harder to shift than ever before.

Added pressure

When crackdowns on illegal gold mining took place in Brazil in the 1970s and ’80s, miners moved en masse to nearby Guyana and Suriname, taking their environmentally destructive technologies with them. Illegal miners of cassiterite are now following a similar pattern, showing that the global effort to reduce deforestation cannot simply focus on a single commodity as a driver of deforestation on the ground.

My work shows that the challenge of mining-led deforestation in the Amazon is rooted in historically informed, global power structures that position the Amazon and its resources as available for extraction by industries and governments in wealthier countries. These groups of people are now seeking to reduce their disproportionately high emissions through technological solutions and not through behavioural change.

These tensions also have roots in the readiness of governments and forest users in postcolonial countries, like Brazil and Guyana, to respond positively and unquestioningly to international demand for these resources.

In the Amazon, outcomes are affected by whether different groups of people have access to livelihoods that do not drive deforestation, such as those based on non-timber forest products. The situation is further shaped by the extent to which governments can work together to ensure that crackdowns in one part of the Amazon, such as Brazil, do not just drive deforestation elsewhere to Suriname, for example.

Until the power structure that disadvantages Indigenous and other historically marginalised groups changes, the negative effects of developing technologies to “save” the planet will continue to disproportionately burden these groups, even as their current way of life remains critical to supporting sustainable development outcomes.
