“HIGHLIGHTS
• The regional pattern of IGF in west-central Florida is dominated by the characteristics of the Upper Floridan Aquifer.
• IGF plays a major role in the available water for partitioning and watershed aridity index.
• Groundwater pumping affects IGF, and the change in IGF counteracts the human impact on available water..."

"This talk by #JamesBridle was part of '#OtherMinds', a season of work exploring different kinds of #intelligence: animal, mechanical, collective. In September 2024, #Watershed shared projects that ask what it means to work with minds that are utterly unlike our own, and how 'AI' can be part of a wider conversation about intelligence, labour, and creativity."

#Solarpunk #writing and #art idea:

A #watershed #map instead of a political or elevation one.

Imagining a world divided into bio-regions not by some arbitrary political body, but by the rivers and water circulation.

We could make it into a beautiful symbol of a sustainable future.

More about it - en.wikipedia.org/wiki/Drainage

The one below is a work of grasshoppergeography.com/

"A Half Built Garden" book by Ruthanna Emrys implements such a vision!

“But whatever the premises of opposition may be, only the most convincing justification under accepted standards of #precedent could suffice to demonstrate that a later decision overruling the first was anything but a #surrender to #political pressure, & an unjustified repudiation of the principle on which the Court staked its #authority….So to overrule under fire in the absence of the most compelling reason to re-examine a #watershed decision would subvert the Court's #legitimacy…”

This is a view of part of the #TsolumRiver.

In 1964, Mount Washington Copper Mining Co. moved into its watershed & built a copper mine. By 1966, they left the area after extracting 940,000 tonnes of waste rock. Even though mining lasted only 3 years, repercussions of the mining practices can still be seen today. What was once a river that was sprawling with 15,000 coho salmon depleted to only 14 by 1984. In 1997, Tsolum River Task Force was formed by over 200 local residents with the goal of restoring Tsolum River's health & productivity.

The river previously supported large populations of salmon, steelhead & cutthroat trout & contributed significantly to the local economy. The economic benefit to the community, in 2007 dollars, was estimated at $2.7 million annually. Past remediation efforts have contributed to improved water quality in the Tsolum River. However, further improvement is needed in order to allow restoration of the fisheries resource.

A 6-ways partnership was founded in 2001 between the BC Ministry of Environment, Timber West, Tsolum River Restoration Society, Pacific Salmon Foundation, Environment Canada & Fisheries & Oceans Canada.
This partnership led to a successful wetland project, which reduced the copper levels to the point that fish stocks have now returned to the Tsolum River. The wetland has a limited life of 5-10 years, after which copper leachate will again impact the emerging fish populations.

“Creating a binational sponge city in the desert: Flooding in the binational cities at Ambos Nogales on the Arizona-Sonora portion of the US-Mexico border has caused damage, ruined livelihoods and taken lives for hundreds of years. New research suggests that flooding can be detained using low-tech, nature-based solutions, like natural infrastructure in dryland streams (NIDS), rock detention structures and green infrastructure.…”
