In water-stressed regions, droughts pose a critical challenge to urban water security for low-income households. Droughts reduce water availability, forcing water providers to invest in additional supplies or enact expensive, short-term emergency measures. These costs are frequently passed on to households through increased rates and surcharges, driving up water bills for low-income households and altering patterns of water consumption. Here we have developed a socio-hydrological modelling approach that integrates hydrology, water infrastructure, utility decision-making and household behaviour to understand the impacts of droughts on household water affordability. We present here an application based on Santa Cruz, California and show that many drought resilience strategies raise water bills for low-income households and lower them for high-income households. We also found that low-income households are most vulnerable to both changing drought characteristics and infrastructure lock-in.

Socioeconomic Disparities in Exposures to PFAS and Other Unregulated Industrial Drinking Water Contaminants in US Public Water Systems

Background: Unregulated contaminants in drinking water, such as per- and polyfluoroalkyl substances (PFAS), can contribute to cumulative health risks, particularly in overburdened and less-advantaged communities. To our knowledge, there has been no nationwide assessment of socioeconomic disparities in exposures to unregulated contaminants in drinking water.Objective: The goals of this study were to identify determinants of unregulated contaminant detection among US public water systems (PWSs) and evaluate disparities related to race, ethnicity, and socioeconomic status.

Striving for Equity in Public Investments in Water in California: An Analysis of Prop 1 Implementation

 In 2014, California voters approved a $7.5 billion bond measure to fund water quality, supply, and infrastructure improvements. Prop 1 included significant provisions to prioritize investments in disadvantaged communities.  For this report, looking at Prop 1 spending midstream, we analyzed the $2.5 billion that had been assigned to projects as of April 2019 out of $7 billion of the bond funding that has been committed so far through budget appropriations. We analyzed how much of that funding is going to projects benefiting disadvantaged communities and technical assistance efforts to increase the capacity of those communities to secure funds and manage projects. The executive summary of this report with our topline findings and recommendations below also serves as an index to the rest of the detailed report that follows. 

Sustainable Development and Environmental Justice

This chapter addresses the incorporation of environmental justice into the general plan. While environmental justice is not a mandatory topic in the general plan, there is a strong case for its inclusion. Federal and state anti-discrimination statutes, which have a long history, apply to planning as they do to other policy areas. As discussed below, environmental justice issues are often related to failures in land use planning. Planning policies that promote livable communities and smart growth can be tools for achieving environmental justice. In keeping with that idea, this chapter begins with a discussion of sustainable development. Sustainable development provides a context for understanding how environmental justice fits into land use planning. This chapter concludes with a discussion of transit-oriented development, which has important implications for environmental justice and sustainable development.

The futures market for water rights trading in California: Analyzing the emergence of a controversial experiment

This paper presents a qualitative case study of the world's first water futures contract in California, a market that enables hedgers and speculators to bet on water prices. It is attempted to explain which factors shaped the emergence of the unique market by applying the Political Process Inherent Dynamics Approach (PIDA), an analytical framework from the field of environmental policy analysis. In addition, the topics of heated debate that have surrounded the new market are summarized and contextualized. To obtain the relevant information, expert interviews, complemented by online sources, were subjected to a Qualitative Content Analysis. It is concluded that the launch of the contract is an extreme case of private business actors shaping water governance, made possible by a longstanding market philosophy in the US, that gives leeway for actors of financialization to create facts. In the political-administrative realm, a lack of accountability and will to interfere seems to prevail. However, nongovernmental organizations (NGOs) and other actors have led efforts to abolish the market, criticizing water futures in ways that resonate with broader debates about privatization and food futures.

The Human Right to Water

More than a billion people lack access to safe drinking water. Two and a half billion people live without access to adequate sanitation systems necessary to reduce exposure to water-related diseases. The failure of the international aid community, nations, and local organizations to satisfy these basic human needs has led to substantial, unnecessary, and preventable human suffering. Tens of thousand of people, mostly young children and the elderly, die every day from water-related diseases. In this analysis, Peter Gleick address three critical questions: 1. Is there a human right to water? 2. If there is a human right to water, what is the advantage and implications of acknowledging such a right? 3. What are the obligations of states, regional governments, organizations, and individuals in achieving these rights? […]

The Human Right To Water In Poor Communities Of Color

Since the state enacted the Human Right to Water Legislation (AB 685) eight years ago, California has added more regulatory authority and more funding to help small disadvantaged or severely disadvantaged community water systems. The California Water Resources Control Board (State Water Board) can order mandatory consolidation to merge failing community systems with another, higher-functioning water system. The State Water Board is authorized to issue an enforcement order to mandate that water systems meet water quality standards. Other recent legislation authorizes the State Water Board to designate an Interim Administrator to manage the system, improve it, or consolidate the water system with another. The newly enacted Safer and Affordable Funding for Equity and Resilience (SAFER) drinking water program calls for annual appropriation of $130 million dollars for ten years to address the problems of disadvantaged community water systems. This report identifies the 64 community water systems in Los Angeles County serving disadvantaged or severely disadvantaged populations.

The role of climate and population change in global flood exposure and vulnerability

Flooding is a pervasive natural hazard with wide-ranging impacts on society. Using a high-resolution global flood model considering coastal, fluvial, and pluvial hazards, we clarify the role of climate effects versus population growth effects in changing flood exposure. Between 2020 and 2100, the population likely exposed to 1% annual risk (100-year) flood hazard will increase from 1.6 to 1.9 billion people. Of this change from the 2020 exposure, we attribute 21.1% to climate change, 76.8% to population change, and 2.1% to both climate and population change. The largest driver of uncertainty in exposure is population change, while climate change remains a smaller but still important driver. The global increase in exposure between 2020 and 2100 is primarily driven by low-GDP regions, and by 2100 the lowest GDP areas will make up 63% of the exposure both overall and in urban areas. Urban areas are especially vulnerable in nearly all global regions, and urban areas sensitive to extreme events are expected to see a 33% increase in population exposure. This study highlights the vast inequities in flood exposure, and future work should direct resources and strategies toward sustainable risk mitigation in these areas.
