This landscape assessment is the outcome of Phase 1 of a tri-phased project and was designed to inform the path forward for engaging the private sector to invest in nature-based solutions (NBS). A literature review was undertaken to understand the contemporary thinking around NBS and identify key opportunities and challenges faced by decision makers, practitioners and researchers. Interviews conducted with representatives of businesses, civil society and academia who have already implemented NBS projects or are looking to do so yielded qualitative responses to complement or contrast with the findings from the literature review.

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 2. This is a small book on a very large topic: water resource system planning. The term water resource system as used here means a combination of structural and nonstructural measures, including rules of operation, for transforming stocks or flows of water into more useful outputs of water, water services, or water-related products. Examples of these outputs would include municipal water supply, flood control, waste disposal and water quality management, navigation, irrigation, and hydroelectric power. Both the original water inputs and the outputs are characterized by quantity, quality, time, and place.

Benefits and Economic Costs of Managed Aquifer Recharge in California

Groundwater management is important and challenging, and nowhere is this more evident than in California. Managed aquifer recharge (MAR) projects can play an important role in ensuring California manages its groundwater sustainably. Although the benefits and economic costs of surface water storage have been researched extensively, the benefits and economic costs of MAR have been little researched. Historical groundwater data are sparse or proprietary within the state, often impairing groundwater analyses. General obligation bonds from ballot propositions offer a strategic means of mining information about MAR projects, because the information is available publicly. We used bond-funding applications to identify anticipated MAR project benefits and proposed economic costs. We then compared these costs with actual project costs collected from a survey, and identified factors that promote or limit MAR. Our analysis indicates that the median proposed economic cost for MAR projects in California is $410 per acre-foot per year ($0.33 per m3 per year). Increasing Water Supply, Conjunctive Use, and Flood Protection are the most common benefits reported. Additionally, the survey indicates that (1) there are many reported reasons for differences between proposed and actual costs ($US 2015) and (2) there is one primary reason for differences between proposed recharge volumes and actual recharge volumes (AFY): availability of source water for recharge. Although there are differences between proposed and actual costs per recharge volume ($US 2015/AFY), the ranges for proposed costs per recharge volume and actual costs per recharge volume for the projects surveyed generally agree. The two most important contributions to the success of a MAR project are Financial Support and Good Communication with Stakeholders.

Better late than never: a synthesis of strategic land retirement and restoration in California

Strategic retirement and restoration of agricultural lands is a critical conservation opportunity globally. The objective of this synthesis was to examine whether ecological habitat assessments, endangered species historical occurrence data, and restoration research can be used to develop evidence-based strategy for retiring and restoring agricultural lands. The San Joaquin Desert (SJD) of California is a prominent example because it experienced an extensive conversion to agriculture. Now, new groundwater regulations will lead to retirement on large areas of agricultural lands over the next 20 years. This presents an opportunity to not only restore some of these lands but also explore the challenges associated with balancing direct human needs with other ecosystem-level functions. California is thus an ideal case study for globally rethinking context-specific, single-case study solutions. We used a systematic review and synthesis to address the following three main questions for habitat recovery of endangered species in the SJD. (1) What are the habitat requirements for key endangered animal species in the region? (2) Is there historical evidence to support an assessment of suitable habitats for these species? (3) What restoration techniques apply to these species? Using the Web of Science and other resources, we reviewed over 1000 independent studies on this topic, refined the evidence, and selected a total of 266 relevant publications. Habitat requirements for each species were described, but there was a critical need to examine quantitative thresholds for these factors to better evaluate habitat suitability of retired lands. There was sufficient evidence of historical vegetation to model suitable habitats and design the physical restoration of retired lands. Direct interventions associated with restoration strategies have been infrequently tested. Sparse and diverse evidence associated with direct experimental manipulations is not uncommon in applied ecology, and synthesis is an excellent tool for highlighting these gaps for future research to examine. This review suggests that retired agricultural land is a viable asset for threatened and endangered species, but to effectively advance restoration research and management, direct tests of restoration techniques and an assessment of relative costs for interventions are needed for a given region.

Beyond Privatization: Restructuring Water Systems to Improve Performance

Water managers face significant challenges meeting the water supply, wastewater collection and treatment, and stormwater management needs of the communities they serve. Numerous solutions have been proposed, including privatization—the controversial action of significantly increased private sector involvement. The debate over privatization overshadows discussion of the determinants of performance. Pacific Institute’s report Beyond Privitization: Restructuring Water Systems to Improve Performance  finds that public versus private is not the bright line that separates success from failure. Researchers Gary Wolff and Eric Hallstein found that performance depends on effective staffing, consistent public support for sufficient funding, better asset management systems, performance measurements and rewards, and more stakeholder involvement and transparency. When increased private involvement or changes in public operations create significant cost savings, as they have in some cases, it is because specific improvements were identified and implemented in one or more of these categories. Beyond Privatization provides a framework for urban and rural municipal-level public decisionmakers to assess problems, identify possible solutions, and choose among these solutions. It provides practical information and examples about improving the effectiveness of water, wastewater, and stormwater systems, whether public or private. To illustrate critical points, the report offers numerous examples from the upper Midwest: the US states of Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio, and Wisconsin, and the Canadian province of Ontario. However, the manual’s lessons extrapolate to other regions of the United States, and beyond.

Beyond Water Pricing: An Overview of Water Financing Options in California

California’s social and economic well-being is directly tied to financing for reliable, sustainable water. A new study from the Pacific Institute explores stable and sustainable sources of funding for water projects as a key to long-term solutions, and finds California’s increased dependence on general obligation (GO) bonds in funding water systems is unreliable and costly to both the state and taxpayers. Current water rates often do not fully cover the cost of providing water services and rarely reflect the full costs of the water itself, such as the ecosystem impacts related to extracting water. California ranks at the top of the EPA’s survey of infrastructure needs in terms of the investments required to maintain aging water systems over the next two decades. Climate change, continued population growth, and restoring critical ecosystems will add further to these costs. “Various financing options are used to invest in existing water systems and services, develop new ones, and mitigate environmental impacts, but there are serious economic and financial challenges,” said Dr. Newsha Ajami, lead author of the report. “The water sector needs a more comprehensive and stable financing portfolio.” According to the California Department of Water Resources, nominal annual debt service for outstanding general obligation water bonds in California has increased four-fold since 2000. This shift to greater use of bond funding can be linked to the decreased ability to raise government revenues through taxes and fees as a result of voter-approved initiatives like Proposition 13 and 218. General obligation bonds, however, are not a steady and reliable source of funding for long-term planning and decision-making because they require voter approval if they survive the legislative process, which is sensitive to economic ups and downs.

Big Valley Groundwater Sustainability Plan

Lassen and Modoc Counties Groundwater Sustainability Agencies | December 8th, 2021

The Big Valley Groundwater Basin (BVGB, Basin, or Big Valley) lies on the border of Modoc and Lassen counties in one of the most remote and untouched areas of California.

The Big Valley Groundwater Basin (BVGB, Basin, or Big Valley) lies on the border of Modoc and Lassen counties in one of the most remote and untouched areas of California. The sparsely populated Big Valley has a rich biodiversity of wildlife and native species who live, feed and raise young on the irrigated lands throughout the Basin. The snow-fed high desert streams entering the Basin have seasonal hydrographs with natural periods of reduced flows or complete cessation of flows late in the summer season. The Pit River is the largest stream and is so named because of the practice, employed by the Achumawi and other Native American bands that are now part of the Pit River Tribe, of digging pits in the river channel when it went dry to expose water and trap game that came to water at the river. Farming and ranching in Big Valley date back to the late 19th and early 20th centuries, when families immigrated to Big Valley and made use of the existing water resources. A large amount of the land in the Basin is still owned and farmed by the families who homesteaded here. Historically, agriculture was complemented by a robust timber industry as a key component of the economy for Big Valley, which supported four lumber mills. Due to regulations and policies imposed by state and federal governments, the timber industry has been diminished over time and subsequently caused a great economic hardship to the Big Valley communities. Stakeholders realize that the Sustainable Groundwater Management Act of 2014 (SGMA) will unfortunately cause a similar decline to agriculture. The change in land management has transformed once thriving communities in the Basin to “disadvantaged” and “severely disadvantaged” communities. Viable agriculture is of paramount importance to the residents of Big Valley because it supports the local economy and unique character of the community. As required by SGMA, stakeholders have developed a sustainability goal: The sustainability goal for the Big Valley Groundwater Basin is to maintain a locally governed, economically feasible, sustainable groundwater basin and surrounding watershed for existing and future legal beneficial uses with a concentration on agriculture. Sustainable management will be conducted in context with the unique culture of the basin, character of the community, quality of life of the Big Valley residents, and the vested right of agricultural pursuits through the continued use of groundwater and surface water. Lassen and Modoc counties are fulfilling their unfunded, mandated roles as Groundwater Sustainability Agencies (GSAs) to develop this Groundwater Sustainability Plan (GSP) after exhausting its administrative challenges to the California Department of Water Resources’ (DWR’s) determination that Big Valley qualifies as a medium-priority basin. Both counties are disadvantaged, have declining populations, and have no ability to cover the costs of GSP development and implementation.
