Impact assessment of agricultural water management interventions in the Jaldhaka watershed
The report uses the Soil Water Assessment Tool (SWAT) and a lumped groundwater model to evaluate the Jaldhaka watershed's current hydrology and the effects of shifting land use or increasing groundwater pumping. It finds that while both a deforestation scenario and an electrification scenario increase rice production, deforestation significantly raises flood risks. Electrification increases productivity but may lead to groundwater depletion of up to 8 meters in downstream areas under a 100% adoption scenario, though this may be partially offset by induced recharge from perennial rivers.

Transitioning Away from Large-Scale Power Projects: a Simple and Effective Fix for the CDM?
The document assesses the impact of large-scale power projects on the Clean Development Mechanism (CDM), noting that these projects are expected to generate nearly 70% of total CERs between 2013 and 2020. It argues that additionality for these projects is difficult to demonstrate, potentially leading to a global increase in greenhouse gas emissions. The authors propose phasing out these projects to stabilize the carbon market and shifting support toward national policies like feed-in tariffs and carbon taxes.

The Reduction in Air Quality Impacts and Associated Economic Benefits of Mitigation Policy: Summary of Results from the EC RTD ClimateCost Project
The document finds that GHG mitigation policies significantly improve air quality by reducing emissions of sulphur dioxide, nitrogen oxides, and particulate matter. In the EU27, this leads to substantial health gains, including an increase in average life expectancy by one month by 2050 and annual economic co-benefits ranging from €44 billion to €95 billion. The analysis also highlights significant benefits in China and India, where life expectancy gains are estimated at 19 and 30 months respectively by 2050. Additionally, mitigation reduces regulatory abatement costs for businesses and lessens the acidification and eutrophication of ecosystems.

The ClimateCost Project. Final Report. Volume 1: Europe
The ClimateCost project estimates significant health risks for Europe under a medium-to-high emission (A1B) scenario, with heat-related mortality and coastal flooding causing the highest welfare costs. Heat-related deaths are projected to reach 127,000 per year by the 2080s, though this is reduced by acclimatisation and mitigation (E1 scenario). Salmonellosis cases and labour productivity losses are also expected to rise, particularly in Southern Europe. The report highlights that technical adaptation, such as sea dikes, can drastically reduce coastal flood fatalities, while other health adaptation measures remain under-researched.

Real People, Real Impacts: The Climate Impact Equity Lens
The Stockholm Environment Institute's Climate Impact Equity Lens (CIEL) tool reveals that while aggregate economic models often suggest modest climate damages, these averages hide a wide disparity in outcomes. By comparing individual climate damages against the savings gained from not reducing emissions, CIEL demonstrates that the most vulnerable people—particularly in poor countries—are already facing net losses. While many currently benefit from the status quo, the tool projects that by 2100, the majority of the global population will suffer net losses, and by 2150, almost everyone across all regions will be net losers, except potentially in China.

Kommunaalteenustega seotud veokite keskkonnamõju vähendamine Tallinnas
The report analyzes transport-related emissions in Tallinn from 2000 to 2009, noting a significant increase in CO2e emissions driven primarily by private car usage. It evaluates various fiscal and regulatory measures to mitigate these impacts, with a specific focus on municipal service vehicles. The study finds that implementing eco-driving training for municipal fleets could reduce CO2e emissions by 1,330 to 2,660 tons annually and save between 0.5 and 1 million euros in fuel costs. Despite strategic goals for sustainable transport, the report concludes that Tallinn's actual progress is hindered by a continued focus on car-centric infrastructure.

Changements climatiques et réduction de la pauvreté
The document examines the intersection of climate change and poverty, highlighting how climate variability makes it harder for the poor to escape poverty. It advocates for a shift toward 'climate-resilient development' by integrating adaptation into national poverty reduction strategies, investing in evidence-based data, and ensuring inclusive processes that involve climate-vulnerable poor populations. The brief notes that while 'triple win' solutions (combining mitigation, adaptation, and poverty reduction) are desirable, they are difficult to implement and often fail to reach the poorest populations. It emphasizes that public investment is essential, as private sector investment alone cannot meet the needs of the Millennium Development Goals (MDGs) and adaptation requirements, particularly in Africa.

Water management, Chinook salmon, California, climate change
Using WEAP and SALMOD models, the study finds that climate change leads to lower summer base flows and higher water temperatures in Butte Creek, increasing adult thermal mortality for spring-run Chinook salmon. While ceasing water diversion for power production improves survival time, the authors conclude that simple operational changes are unlikely to prevent the long-term extinction of the species in this location.

Climate Change and Your Health: Rising Temperatures, Worsening Ozone Pollution
The document details how climate-induced temperature increases exacerbate ground-level ozone pollution, leading to significant respiratory health burdens and economic costs. For the continental United States, the "climate penalty on ozone" is projected to cause millions of additional acute respiratory symptoms and thousands of additional hospitalizations for infants and seniors by 2020 and 2050, with health impact costs estimated at $5.4 billion in 2020 alone. In California, these effects could result in nearly 443,000 additional cases of serious respiratory illnesses and costs exceeding $729 million in 2020.

Food Security: The Tanzanian Case
The 2007–08 international food crisis had a modest impact on Tanzania compared to other poor countries, with an estimated 0.5–1% of the population driven into poverty, primarily in urban areas. While short-term government interventions like export bans and tariff reductions showed limited evidence of effectiveness, long-term economic reforms since the early 2000s helped the country maintain agricultural exports. The study highlights a persistent challenge in stabilizing agricultural output growth and suggests that greater integration with global markets could serve as insurance against domestic production shocks.
