[My sincere thoughts to those on those the Nepal/Tibet border so very effected by the recent GLOF-style flooding; the loss of your family and friends – and ‘things’ – must be so very hard!
May the missing individuals return safely. 🙏]

“What happens when communities face 'too much water' during the monsoon and 'too little water' during the dry season? [Their] research in Dudhauli and Siraha municipalities [Nepal] shows that floods and droughts are not merely environmental challenges; rather, they interact with existing inequalities and vulnerabilities, intensifying conflicts over water and land resources.
From upstream-downstream tensions following flood damage and changing water flows to competition over wells and handpumps during periods of scarcity, the findings show that hydro-climatic extremes often act as amplifiers of existing social, economic, and political vulnerabilities.
The study underscores the importance of moving beyond managing climatic hazards alone towards conflict-sensitive and equitable water governance that addresses structural inequalities, strengthens local adaptive capacities, and supports fair water allocation and conflict resolution…”

“[The author has] already discussed ancient water management systems, such as the qanats in Persia and other Eastern countries. In Europe, there are the acequias of the Sierra Nevada in Andalusia, Spain.
The hand-dug channels date back over 1,000 years to the Moorish era. Networks of canals, aqueducts and cisterns were engineered to capture and transport snowmelt, turning this natural resource into a sustainable water supply for agriculture. The high-altitude ditches had openings, allowing water to infiltrate into fractures and faults, replenishing the aquifer, and to irrigate the lower levels of the slopes.
𝗪𝗵𝗮𝘁 𝗱𝗲𝗳𝗶𝗻𝗲 𝗮𝗰𝗲𝗾𝘂𝗶𝗮𝘀?
✅ Gravity-fed irrigation that supported terraced farms and local biodiversity.
✅ Designed to distribute water slowly and equitably, even during dry summers.
✅ Stretching over thousands of kilometres, these systems fell into disuse in the 1980s but are now part of restoration efforts led by the MEMOLA Project (Universidad de Granada).
With climate change and more intense droughts, the Acequias could provide an ancient solution to the modern-day water crisis…”

"We don't expect any conflict with the beaver in the next 10 years," ~ Bohumil Fiser from the Czech Nature Conservation Agency
--
“For seven years, planners struggled to complete a $1.2 million wetland restoration project in the Brdy region of the Czech Republic. The goal was to build a dam that would improve water management and bring back valuable wetland habitat, but the project remained trapped in a maze of permits and approvals.
Then a family of eight Eurasian beavers did what engineers had planned… without permits, machinery, or a budget.
The beavers built a network of dams in almost the exact area chosen for the proposed project, naturally restoring the wetland system officials had spent years trying to create. After seeing the results, authorities decided there was little point continuing with the original human-built dam.
Although some reports suggested the beavers completed the work overnight, experts say their construction likely took several weeks. The reason it seemed sudden is that the animals quietly worked away until their finished dams became impossible to miss.
Beavers are known as “ecosystem engineers” because their behaviour can reshape entire environments. By cutting trees and blocking streams, they create ponds and wetlands that support countless species, including fish, amphibians, insects, birds, and mammals.
Their wetlands also act as natural water reservoirs, helping during droughts, reducing flood risks, filtering water, storing carbon, and keeping landscapes wetter during wildfires…
Once heavily hunted across Europe, beaver populations have been recovering thanks to conservation efforts, proving that sometimes nature can solve problems humans spend years trying to fix…"

[Flash floods? not TOO hard to conceptualise.
Flash drought? harder to 'get my head around', but H/T / presenter does an excellent job!]
"Not all droughts are the same. In some cases, drought rapidly intensifies at subseasonal to seasonal scales with significant impacts to agriculture and water resources along with the increased propensity for heatwaves and wildfires. Like all droughts, flash drought begins with a precipitation deficit. However, both evaporative demand and soil moisture are critical flash drought variables, and identifying and monitoring the desiccation of the terrestrial surface is key for determining flash drought development and associated impacts. While recent advances in knowledge and monitoring of flash drought have occurred, fundamental questions remain in the state of the science. What are the overall mechanistic relationships between atmospheric demand, evaporative stress, terrestrial desiccation, and precipitation that drive the progression of flash drought? Do regional characteristics of the environment impact the evolution of flash drought? What are the scales of predictability for flash drought? Finally, how will flash drought frequency and intensity evolve in a changing climate system"
--
"Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation. These changes in the weather increase evapotranspiration and lower soil moisture. Flash droughts can cause extensive damage to agriculture, economies, and ecosystems if they are not predicted and discovered early..."

Irrigation, pouvoir et despotisme : ce que Claessen conteste chez Wittfogel

H. J. M. Claessen (1973) montre que l’irrigation ne produit pas mécaniquement le despotisme : les grands travaux hydrauliques peuvent renforcer un pouvoir déjà centralisé, mais ils n’en sont pas la cause unique. #waterManagement #hydraulicInfrastructure #centralization #state #anthropology #power Dans “Despotism and Irrigation”, H.
