Thermodynamic Modeling & Policy Relevance

As regulatory discussions and technical feasibility studies for the Svystunova Gully mine-water retention system (2026–2027 period) get underway, integrating rigorous thermodynamic modeling into the engineering baseline is critical.

Simple dilution metrics do not account for mass-balance limits, bedrock dissolution, concrete leaching, or secondary mineral precipitation along the waterway. Following today’s session of the government interdepartmental working group, I submitted key findings from my open-access research to support evidence-based decisions. The submitted package includes speciation models, phase equilibria calculations, and reactive transport assessments focused on mining wastewater management and dam stability evaluation.

H/T @ Prakriti Niraula | Researcher at Kathmandu University School of Arts | Urban FutureScape Pilot Project | Urban Governance | Climate and Disaster Resilience | Development Researcher
“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…”

Modeling Climate Change Impacts On Blue And Green Water In The Ethiopian Upper Blue Nile Basin

H/T @Dessalegn worku Ayalew
“The present study assesses the impacts of climate change on blue and green water in the Kessie Watershed of the Ethiopian Upper Blue Nile Basin using the SWAT+ model.
[The authors] set up [a] SWAT+ model using quality-controlled and homogenized observational climate time series… and calibrated it using a multisite calibration approach. [They] selected CMIP6 climate models for future simulations and bias-correction methods through a comprehensive performance assessment... Building on these previous studies, the present research further evaluates the reliability of combining robust climate-model selection with optimal bias-correction methods to improve the reliability of hydrological simulations. [They] then used the best-performing climate models, bias-corrected using the optimal methods, to project future changes in blue and green water in the study area…
KEY FINDINGS:
• SWAT+ effectively represented hydrological processes across multiple gauging stations in the Ethiopian Upper Blue Nile Basin.
• Ensembles of CMIP6 climate models improved the reliability of hydrological simulations compared with individual climate models.
• Optimized climate-model selection reduced biases in hydrological simulations more than bias correction alone.
• Arbitrary selection of climate models can degrade hydrological simulations, even when their outputs are bias-corrected using robust methods.
• Both blue and green water are projected to increase under future climate change in the Ethiopian Upper Blue Nile Basin.
• Blue water exhibits greater seasonality and climate sensitivity than green water flow and green water storage.
The study also provides sustainable water management options for adapting to the impacts of climate change, with implications for water resource planning and management in the Upper Blue Nile Basin…”

This is a very long shot (and has nothing to do with history & co :sadness: ), but does anyone know of a database/book/compehensive list, or someone who might know one, about crop responses to deficit irrigation?

Also: accessible without academic affiliation.

Creating a sustainable future for the African child: a #solarpunk concept

by Christabel Ebubechukwu Okoroafor, Bachelor of science student, Social work department, University of #Nigeria, Nsukka, Nigeria.

PEOPLE CENTRED –THE JOURNAL OF DEVELOPMENT ADMINISTRATION | Volume 9, Issue 2, 2024

Abstract
"This article investigates the conceptualization and integration of the formerly known literary genre and art form; now a subgenre of climate activism, solarpunk as a way of building a sustainable future for the African child; a future that takes pride in preserving the planet and creating a safe space for the African child to thrive, survive and develop. Solarpunk is a speculative and optimistic concept that seeks to reimagine the future of sustainability and mitigate climate change; an #ecotopian future where technology especially renewable resources and nature exist in #ecological harmony (#symbiotism). It profers #sustainable solutions like that embodies the core concept of African philosophy- being a whole person and being one with your surroundings, particularly focusing on community and its strength, a core concept for the Africa scene. It encourages social action through sustainability education of the next generation that is the African child. It integrates evidence from reviews, personal correspondence and diaries. With the potential to address challenges faced by African children, the article is arranged in sections that: introduce solarpunk and its alignment with African philosophies, analyze the current challenges faced by African children, present the context of #ClimateAction through the lens of #BAIW (Because Africa Is Worth It), present practical applications of solarpunk principles, discuss the role of #ForestGuards and social action groups in #biodiversity preservation, and explore how solarpunk addresses the challenges of the African child, concluding with policy recommendations to support the adoption of solarpunk in #Africa."

Where ‘#DayZeroDroughts’ could happen as soon as this decade

Story by Laura Paddison, September 23, 2025

Excerpt: "Cities are particularly at risk as booming populations increase demand on water resources already under pressure from #ClimateChange and mismanagement. Low-income communities are expected to be disproportionately affected, the study found.

"Some parts of the world, including the Mediterranean, southern Africa, Asia and Australia, are projected to endure more prolonged day-zero drought events with less time between each one, limiting their ability to recover, the report found. This can have devastating effects on agriculture and ecosystems, and for some particularly badly affected areas, it throws into question 'whether people might still be able to live there long term,' Franzke said.

The findings point to the clear need to speed up the clean energy transition, he said, as well as improve water management — huge amounts are wasted through leaky pipes, for example.

"The research should also guide industry, he added, pointing to the proliferation of water-guzzling #SemiconductorManufacturing and #DataCenters in water-stressed areas such as #Texas and #Arizona."
