From the SJV Greenprint Phase II Summary Report:

"The San Joaquin Valley (SJV) is one of the world’s most productive agricultural regions; is a vital link in California’s complex water delivery and transportation systems; provides important habitat to protect biodiversity; and is a center for oil and solar energy production. The region has a unique set of assets and challenges related to its agricultural land, growing population centers, biodiversity, energy production, and water availability.

The San Joaquin Valley Greenprint project grew out of the San Joaquin Valley Blueprint... The Blueprint focused on urban challenges, particularly the relationship of land use to transportation, and developed a set of smart growth principles that should minimize development impacts on the non-urban lands of the Valley. The Blueprint revealed the need for better regional mapping of the Valley’s non-urban areas to assist land use and resource management decisions...

The SJV Greenprint is primarily a collection of maps, assembled as a comprehensive, interactive database that catalogs current conditions and trends related to the region’s resources. The maps and data collected for the SJV Greenprint are publicly available through the San Joaquin Valley Data Basin Gateway (http://sjvp.databasin.org)... The collection demonstrates how these resources are interrelated across political boundaries and how they are changing under the influence of population growth, changing land use practices, resource limitations, and changing climate. 

Phase I of the Greenprint focused on identifying and mapping Valley resources for the eight counties that comprise the San Joaquin Valley, including Kern, Tulare, Kings, Fresno, Madera, Merced, Stanislaus, and San Joaquin Counties... The compiled information includes over 100 datasets related to agriculture, biodiversity, energy, and water resources, as well as supplemental datasets including land use planning, transportation, soils, and land cover...

Phase II of the SJV Greenprint was intended to build on and extend the work in Phase I by demonstrating the real world utility of this information. The Demonstration Projects, described in Section IV, serve as case studies for the use of Greenprint data. A second objective of Phase II was to find an appropriate platform for these curated resources, specifically a host that could provide a user-friendly interface as well as the capacity to update and maintain the data. The San Joaquin Valley Gateway, hosted by Data Basin, was identified as the best platform... A third objective of Phase II was to shed light on key questions and insights into various resource management challenges in the Valley through outreach to experts, regional councils of government, and county planning directors...

​Summary and Conclusions from SRT’s San Joaquin Valley Greenprint Demonstration Project
 
The State of the Valley Report identifies water as “one of the central management challenges of the San Joaquin Valley,” and emphasizes that “[b]oth surface water and water pumped from underground aquifers are critical to the region’s farming, ranching, urban users, industry, and natural ecosystems.”[1]  Implementation of the Sustainable Groundwater Management Act (SGMA) is just beginning,[2] but the overall dialogue about water sustainability has focused more on technological solutions than on ways to improve the natural ability of watersheds to absorb, store and gradually release water in forms useful to people and the land.  Sequoia Riverlands Trust’s (SRT’s) San Joaquin Valley Greenprint Demonstration Project explores the potential contribution of land-based strategies to watershed effectiveness, usable water supply and groundwater sustainability, focusing on three themes:

• Soil Enhancement and Water Resources;
• Floodwater Threats and Opportunities; and
• Mineral and Water Resources.

 
These approaches are not new.  Many have been extensively researched, incorporated into funding programs and regulatory requirements, and applied to varying degrees.However, relatively little attention has been paid to the relationship of these land-based strategies to effective watershed function and groundwater sustainability.  Sequoia Riverlands Trust applied existing Greenprint data and other information to map areas where these approaches might yield the greatest water-related benefits, and to roughly quantify their potential contribution to groundwater sustainability in the Kaweah and Tule River Watersheds.
 
Our results suggest that practical applications of these strategies could offset at least 25% of the annual groundwater deficit in the Kaweah and Tule River Watersheds by addressing both the supply and demand sides of the water balance equation.  This assertion is based on estimates that:

• Soil organic matter-enhancing land management practices have the potential to increase the effective capture of precipitation by at least 14,500 AF, both reducing the need for supplemental irrigation and increasing the amount of water available for recharge;
• On-farm flooding and recharge could reduce annual groundwater overdrafts by up to 20% based on studies of similar groundwater basins in other parts of the Southern San Joaquin Valley; and
• Projects that restore at least some natural function to modified floodplains (e.g., at reclaimed alluvial mines, streamside areas of farms and ranches, or sites like SRT’s Kaweah Oaks Preserve) could make a measurable contribution to groundwater recharge by slowing floodwaters down and providing larger areas for infiltration.

 
Furthermore, all of these land-based strategies provide additional ecological, economic and community benefits, such as increased agricultural production, flood management, habitat enhancement, drought resilience and aesthetic values, that make them politically palatable alternatives to new dams or regulations about water use.  Water-focusedland conservation, restoration and management strategies therefore deserve serious consideration as we work together to solve our region’s pressing groundwater sustainability concerns.
