The document outlines four plausible scenarios for the year 2010 based on federal regulatory roles and financial environments. It advocates for a 'water soft path' paradigm shift, moving from centralized, demand-driven 'gray infrastructure' toward decentralized, efficient, and integrated 'green infrastructure.' The author identifies drivers for this transition, including end-use efficiency, waterless sanitation, stormwater harvesting, and technological spill-overs from the distributed energy revolution, such as fuel cells and hybrid-electric vehicles.

The report argues that water must be framed not just as a sector but as a cross-cutting enabler of social development, economic growth, and environmental integrity. It proposes a 'cross-cluster framework' that integrates three perspectives: water as a sector, an enabler, and a supporter. The authors estimate that implementing water-related SDGs would require annual global investments between US$1.25 and 2.25 trillion over 20 years, representing 1.8% to 2.5% of global GDP. Key challenges identified include systemic corruption in the water sector, a critical lack of operation and maintenance funding, and the need for a paradigm shift from donor-led to multi-stakeholder governance.

The document examines how water risks—driven by population growth, economic expansion, and climate change—contribute to political instability and food insecurity. It identifies three primary pathways to water insecurity: diminished supply or quality, increased demand, and extreme flood events. The text emphasizes that water crises are contributing factors rather than sole causes of conflict, with outcomes heavily dependent on a community's governance capacity and resilience. Proposed mitigation strategies include improving irrigation efficiency, implementing water demand caps, and strengthening governance systems.

The study examines the water-energy nexus in Qingdao, finding that while unconventional water sources like seawater desalination are necessary to meet growing demand, they significantly increase energy intensity and carbon emissions compared to local surface water.

The document describes eutrophication as a growing environmental crisis, noting that over 500 coastal areas are impacted and dead zones increased from 10 cases in 1960 to 405 in 2008. It attributes this trend to human activities, specifically wastewater, agriculture, and nitrogen deposition from fossil fuel combustion. The brief predicts that eutrophication will continue to increase, particularly in the developing world, driven by a projected population of 9.2 billion by 2050, a 54 percent expected increase in global meat consumption between 2002 and 2030, and a 50 percent projected growth in energy consumption from 2005 to 2030.

The African Cities Water Adaptation Fund (ACWA Fund) aims to leverage $5 billion by 2032 to implement urban water resilience projects in 100 African cities. The fund employs a blended finance model—combining grants, concessional loans, equity, and debt—to support the full project lifecycle, from risk-based city water plans to the creation of standardized toolkits for scalable solutions. It focuses on an 'investment menu' of low-cost, replicable solutions such as nature-based solutions for flood and wastewater management, rainwater harvesting, and on-site sanitation.

California's agricultural industry, particularly in the Central Valley, is facing devastating impacts from a multi-year drought described as the worst in 1200 years. The Alliance for Water Stewardship (AWS) standard is being used by companies like Diageo (Blossom Hill winery) and Olam to move beyond basic efficiency toward comprehensive water stewardship. For Diageo, this involved creating an internal "Blue Team" of employees to identify water-saving measures and improve watershed awareness. For Olam, the AWS framework led to the implementation of wastewater treatment via Sudan grass, cascading cleaning systems, and the engineering of multi-crop equipment that enables farmers to invest in drip irrigation. Both companies used the AWS standard to translate global corporate water commitments into local action by recognizing water as a shared resource.

The document outlines various dry sanitation options for residents of Cape Town facing severe water scarcity, specifically in preparation for 'Day Zero'. It explains the risks of using sea water in sewer systems, the health differences between urine and faeces, and provides detailed guidance on implementing dry compost toilets, pit latrines, commercial systems, and chemical toilets.

A 2020/21 WWF study identifies significant faecal contamination in the Crocodile and Sabie Rivers, where E. coli levels frequently exceed safety guidelines for irrigation. This pollution, caused by failing wastewater infrastructure and poor sanitation, poses severe health risks, particularly for subsistence farmers growing high-risk crops like leafy greens. The document recommends a combination of improved governance, targeted farming techniques, and a community-private-public partnership to manage water quality and ensure food safety.

The document defines 'Day Zero' as a worst-case scenario where Cape Town's taps run dry, predicted for 21 April based on dam levels being 28% full as of 15 January. On this day, the city enters Emergency Stage 3, cutting off water to most households and businesses, leaving only vital services and 200 points of distribution providing 25 litres per person. Recovery is expected to take three to six months, depending on winter rainfall. While new sources like groundwater, desalination, and reclaimed water are planned (totaling 292 million litres per day by year-end), they will not meet the current demand of 600 million litres per day. The briefing advises residents to monitor water use, prepare emergency drinking water, and consider dry sanitation systems.
