The United States generates over 250 million tons of municipal solid waste and 9 trillion gallons of wastewater annually, yet recovers less than 18 percent of the potential 10.5 million metric tons of biomethane available. Current landfill systems are inefficient, leading to significant fugitive methane emissions, while many wastewater treatment facilities lack anaerobic digesters or flare excess biogas. The document advocates for a shift toward organic waste diversion and anaerobic digestion, which can result in negative lifecycle emissions. It highlights the potential for waste-derived fuel to power 10.4 million cars or 13.7 million homes and suggests that the EPA's designation of biogas-derived electricity as a renewable biofuel could generate 90 million renewable identification numbers (RINs) annually to support electric vehicle infrastructure.

The report assesses the water-stressed environment of South Africa and the Western Cape, highlighting the risk that water scarcity may constrain economic development. It outlines the governance structure under the National Water Act and Water Services Act, identifies seven key opportunity areas for the private sector—including invasive alien plant clearing and wastewater treatment—and discusses infrastructure projects such as the Clanwilliam Dam and various desalination plants. It also notes significant barriers, particularly chronic skills shortages in municipal engineering and management.

South Africa is over-exploiting its freshwater resources, with a projected widening gap between supply and demand by 2035. The authors find that the National Water Resource Strategy 2013 (NWRS2) lacks the aggressive measures needed to close this gap, which is driven by urban migration, industrial growth, and agricultural expansion. Proposed solutions include significant reductions in municipal non-revenue water, increased wastewater reuse, and expanded groundwater extraction.

The 'Water for Our Future' event, hosted by the World Water Council, WWF, and The Coca-Cola Company, focused on three themes: Green Growth, Water Stewardship and Industry; Water for Food; and Enough Safe Water for All. The forum emphasized the necessity of 'multisector partnerships' and a shift from short-term water projects to long-term water services. Key discussions highlighted the undervaluation of water in the US, the critical role of farmers in water stewardship, and the need for inclusive planning that incorporates local communities and women. The report also presents case studies on the 'golden triangle' partnership in the Rio Grande/Rio Bravo basin and a public-private partnership for wastewater treatment in Jordan.

The report examines South Africa's water sector, highlighting the country's status as the 30th driest globally and the resulting pressure on water resources. It details the governance roles of the Department of Water Affairs (DWA), water boards, and municipalities, while identifying critical challenges such as non-revenue water (approximately 36.8% of supply) and a chronic shortage of engineering skills. In the Western Cape, the report notes a high reliance on six major dams and the implementation of the Berg River Improvement Plan to address pollution. Future opportunities for the private sector are identified in desalination, artificial aquifer recharge, water re-use, and infrastructure maintenance, supported by various government grants like the Municipal Infrastructure Grant (MIG).

The report assesses South Africa's water-stressed environment, highlighting the dominance of agricultural water demand and critical challenges such as non-revenue water losses and a severe shortage of technical skills. It details the governance roles of the Department of Water Affairs and various grants available for municipal infrastructure. In the Western Cape, the report identifies specific projects like the Berg River Improvement Plan and various wastewater treatment plant upgrades as key areas of activity and private sector opportunity.

The Shree Krishna Gyan Mandir Water and Nutrient Testing Laboratory and Research Centre was opened in August 2013 in Patna, Bihar, through a collaboration between the Stockholm Environment Institute (SEI) and the Water, Sanitation and Hygiene Institute (WASHi). The non-profit facility provides high-standard analyses of water quality and the nutrient content of 'humanure' products—including treated urine, greywater, and liquid from composting toilets—to provide scientific credibility for ecological sanitation (ecosan) models. The laboratory follows National Rural Drinking Water Programme (NRDWP) guidelines, can perform 30 analyses per day, and offers services to civil society, schools, and communities to support water conservation and public health. Initial findings from the lab have confirmed the presence of arsenic in wells across Bihar. To ensure long-term sustainability, the laboratory employs a cost-recovery tariff for operational expenses and offers training courses, while seeking statutory accreditation to increase its professional status and client base.

The study estimated that the La Vieja river basin receives approximately 15 tons of pollutant load per day, primarily from domestic sources. By integrating WEAP and QUAL2K tools, the project modeled 12 tributary sources and identified six sub-basins responsible for 96% of the pollutant load. The analysis included a participatory XLRM process to identify 14 uncertainties and 10 management strategies, while incorporating 30 climate change scenarios for the 2010-2050 period to support institutional decision-making.

The report details how the Israeli occupation of the West Bank manifests as an 'environmental Nakba,' involving the systematic expropriation of land and water, the dumping of toxic and nuclear waste, and the establishment of polluting industries in 'seam zones.' It highlights specific cases such as the villages of Kafr Dik and Om Elkheir, and the Wadi Qana nature reserve, to illustrate how environmental degradation and 'green washing' are used to displace Palestinians and facilitate settlement expansion.

The report finds that current algal biofuel technologies are not yet economically or environmentally superior to fossil fuels, citing low energy return on investment (EROI) and high greenhouse gas emissions. While theoretical yields are high, large-scale commercialization is estimated to be years or decades away. The document argues that viability depends on integrating production with wastewater treatment, industrial flue gas for CO2, and the development of marine algae strains via molecular engineering to reduce freshwater and land demands.

The report examines water governance in four European countries, focusing on the implementation of the EU Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). It finds that while there is a general shift toward integrated, river-basin-based management, significant challenges remain in coordinating freshwater and marine policies, managing spatial boundaries, and ensuring meaningful stakeholder participation. The study highlights diverse models of service delivery, from the privatized system in the UK to the public-private partnerships and user associations in Spain, and the strong tradition of community-led water protection in Finland.

The study concludes that nutrient trading in the MRB is economically feasible, as wastewater utilities could significantly reduce costs by purchasing credits from the agricultural sector. Using case studies of two utilities and six agricultural watersheds, the report finds that nitrogen (N) supply is sufficient to meet demand, while phosphorus (P) supply is more limited. It highlights that some conservation practices are profitable for farmers even without trading due to fertilizer savings and yield increases. However, the report notes that the lack of a strong policy driver, potential local water quality standards, and regulatory capacity are significant barriers to implementation.

The document identifies China's urbanization as a critical factor for global climate change, noting that by 2030, China will have approximately 1 billion urban residents. It argues that the current development pattern of 'single use superblocks served by auto-centric transportation' is unsustainable and leads to congestion and pollution. To counter this, the authors propose six 'ingredients for success': permeable urban form (smaller, mixed-use blocks), transit-centered transportation (prioritizing walking, biking, and Bus Rapid Transit), effective and enforced building codes, municipal finance reform to move away from land-leasing incentives, new sustainability performance metrics for mayors, and a strengthened planning process with increased technical capacity.

The CER evaluates the draft NWRS2 against its previous 'Stop Treading Water' report, supporting goals to improve Department of Water Affairs (DWA) stability and the establishment of Catchment Management Agencies (CMAs). However, it criticizes the draft for lacking specific timeframes and financial details, failing to afford legal status to Catchment Management Forums (CMFs), and omitting necessary reforms for the Water Tribunal. The CER specifically warns that proposed revisions to the 'Reserve' for economic development may complicate its implementation and threaten ecosystems.

The research analyzes climate change adaptation in Stockholm's water supply and wastewater sector, finding that most measures focus on building adaptive capacity rather than implementing final decisions. The ability of organizations to pursue adaptation options is primarily driven by their capacity to justify additional resources, either through the application of climate knowledge or by citing existing rules and regulations.

The MENA region faces severe climate vulnerability characterized by warming and water scarcity, yet adaptation and mitigation efforts are often siloed. The document proposes a 'nexus' approach that integrates water and energy planning to identify synergies, such as solar desalination or energy recovery from wastewater, and recommends the use of integrated tools like WEAP and LEAP to move beyond reactive, short-term coping measures.

The report critiques a study by the Utility Solid Waste Action Group (USWAG) which claimed that strict coal ash regulation could lead to the loss of 183,900 to 316,000 jobs. The author argues these figures are based on arithmetic errors, a misapplication of an unpublished academic paper, and unfounded claims regarding 'regulatory stigma'. Using the IMPLAN model and a high-end cost estimate from the Electric Power Research Institute (EPRI) of $6.47 billion annually, the author calculates that the spending required for waste management, wastewater treatment, and construction would create 117,000 jobs, while the resulting electricity price increases would cause a loss of 89,000 jobs. The final result is a projected net gain of 28,000 jobs.

The document details South Africa's efforts to increase water access, which has risen from 62% in 1994 to 93% in 2011. It highlights strategic water infrastructure projects, such as the Mokolo and Crocodile River (West) project and the Spring Grove Dam, alongside a focus on groundwater and desalination. Environmental priorities include combating rhino poaching, implementing the Waste Act to foster a recycling sector, and finalizing a Climate Change Response Policy White Paper ahead of the UN Climate Change conference in Durban. The Minister emphasizes the role of the environment sector in job creation through programs like Working for Water and Working for Wetlands.

The National Strategy for Water re-use, published by GreenCape in June 2011, outlines a framework for implementing water re-use projects in South Africa to address the country's water-stressed status. It defines various types of re-use, analyzes drivers such as cost and public perception, and identifies sector-specific needs in agriculture, industry, mining, and power generation. The strategy proposes a policy environment focused on clear guidelines, updated water quality standards, and the leveraging of private sector capacity to ensure sustainable water resource management.

The BIO-EARN programme (1999–2010) aimed to empower Ethiopia, Kenya, Tanzania, and Uganda to utilize agricultural, environmental, and industrial biotechnologies for sustainable development. Funded by Sida and coordinated by the Stockholm Environment Institute and later the Inter-University Council for East Africa, the programme focused on human capacity building, infrastructure development, and the creation of an enabling policy environment. Key achievements include the training of 30 PhD and 30 MSc students, the upgrading of 17 laboratories with over SEK 25 million in investment, and the development of stress-tolerant sorghum and disease-resistant root crops. The programme also pioneered biosafety risk assessment and intellectual property management in the region, facilitating the transition of research from laboratories to pilot-scale applications in waste water treatment and agro-processing.
