From the IPCC Press Release:​

Limiting global warming to 1.5ºC would require rapid, farreaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5ºC compared to 2ºC could go hand in hand with ensuring a more sustainable and equitable society, the Intergovernmental Panel on Climate Change (IPCC) said on Monday.

The Special Report on Global Warming of 1.5ºC was approved by the IPCC on Saturday in Incheon, Republic of Korea. It will be a key scientific input into the Katowice Climate Change Conference in Poland in December, when governments review the Paris Agreement to tackle climate change.

“With more than 6,000 scientific references cited and the dedicated contribution of thousands of expert and government reviewers worldwide, this important report testifies to the breadth and policy relevance of the IPCC,” said Hoesung Lee, Chair of the IPCC.

Ninety-one authors and review editors from 40 countries prepared the IPCC report in response to an invitation from the United Nations Framework Convention on Climate Change (UNFCCC) when it adopted the Paris Agreement in 2015.

The report’s full name is Global Warming of 1.5°C, an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.

“One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1°C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” said Panmao Zhai, Co-Chair of IPCC Working Group I.

The report highlights a number of climate change impacts that could be avoided by limiting global warming to 1.5ºC compared to 2ºC, or more. For instance, by 2100, global sea level rise would be 10 cm lower with global warming of 1.5°C compared with 2°C. The likelihood of an Arctic Ocean free of sea ice in summer would be once per century with global warming of 1.5°C, compared with at least once per decade with 2°C. Coral reefs would decline by 70-90 percent with global warming of 1.5°C, whereas virtually all (> 99 percent) would be lost with 2ºC.

“Every extra bit of warming matters, especially since warming of 1.5ºC or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems,” said Hans-Otto Pörtner, Co-Chair of IPCC Working Group II.

Just days before the world comes to San Francisco for the Global Climate Action Summit to collaborate on ways to protect the environment, Governor Edmund G. Brown Jr. signed an executive order to safeguard California’s unique plants, animals, and ecosystems which are threatened by climate change. The steps outlined in the executive order and complimentary California Biodiversity Initiative will improve understanding of the state’s biological richness and identify actions to preserve, manage, and restore ecosystems to protect the state’s biodiversity from climate change.

The Nature Conservancy has recently created a map overlaying GDEs and GSA boundaries. The map allows users to view where GDEs are located in their sub-basin, as well as the dominant species in each GDE. This map is a complement to the iGDE mapping mentioned below, which includes a document explaining the source of the data in the database.
 
If stakeholders, GSAs or consultants are interested in learning more about how to comply with requirements to consider GDEs, we are offering an interactive workshop at the Groundwater Resources Association Western Groundwater Conference. The workshop is on Sept. 26 from 2:30-5pm and registration is required.

If there are any questions related to any of this information, please feel free to contact me or Susan Tatayon, statayon@tnc.org.

From the workshop registration page:
"SGMA empowers local agencies to sustainably manage groundwater to benefit California’s communities, economy, and diverse natural resources.  To do this, SGMA requires local agencies to develop groundwater sustainability plans (GSPs) that consider the impacts of groundwater use on a variety of beneficial uses and users including people, business, and the environment.  SGMA also includes specific requirements to identify and consider impacts to groundwater dependent ecosystems (GDEs) in groundwater management.  Recognizing data and resource limitations, The Nature Conservancy has developed a GDE indicators mapping database in partnership with the California Department of Water Resources (DWR) and Department of Fish and Wildlife,  as well as a guidance document designed to help agencies identify where GDEs exist, determine whether potential effects on GDEs are occurring or may occur due to groundwater conditions, and consider GDEs when setting sustainable management criteria.  These tools provide a systematic and defensible approach that takes advantage of local, statewide, and best available scientific information to inform local decision making. This hands-on workshop will walk attendees through the GDE indicators mapping database (hosted by DWR as the “Natural Communities Commonly Associated with Groundwater dataset”) and GDE guidance document.  This is your opportunity to do a preliminary assessment of the GDEs in your basin with support from TNC and other practitioners.  Whether you are a board member on a GSA, a consultant developing a GSP, or an interested stakeholder trying to understand how GDEs fit into GSPs – this is the workshop for you!
MUST BE A REGISTERED CONGRESS ATTENDEE TO ATTEND
There is no additional charge for this workshop but space is limited so please RSVP  in order to save yourself a seat."

hen John Wick and his wife, Peggy Rathmann, bought their ranch in Marin County, Calif., in 1998, it was mostly because they needed more space. Rathmann is an acclaimed children’s book author — “Officer Buckle and Gloria” won a Caldecott Medal in 1996 — and their apartment in San Francisco had become cluttered with her illustrations. They picked out the 540-acre ranch in Nicasio mostly for its large barn, which they planned to remake into a spacious studio. Wick, a former construction foreman — they met when he oversaw a renovation of her bathroom — was eager to tackle the project. He knew the area well, having grown up one town away, in Woodacre, where he had what he describes as a “free-range” childhood: little supervision and lots of biking, rope-swinging and playing in the area’s fields and glens.
The couple quickly settled into their bucolic new surroundings. Wick began fixing leaks in the barn. Rathmann loved watching the many animals, including ravens, deer and the occasional gopher, from the large porch. She even trained the resident towhees, small brown birds, to eat seed from her hand. So smitten were they with the wildlife, in fact, that they decided to return their ranch to a wilder state. For nearly a century, this had been dairy country, and the rounded, coastal hills were terraced from decades of grazing. Wick and Rathmann would often come home and find, to their annoyance, cows standing on their porch. The first step they took toward what they imagined would be a more pristine state was to revoke the access enjoyed by the rancher whose cows wandered their property.
Within months of the herd’s departure, the landscape began to change. Brush encroached on meadow. Dried-out, uneaten grass hindered new growth. A mysterious disease struck their oak trees. The land seemed to be losing its vitality. “Our vision of wilderness was failing,” Wick told me recently. “Our naïve idea was not working out so well.”
Wick was especially bothered by the advance of a prickly, yellow-flowered invasive weed called the woolly distaff thistle. He pulled it, mowed it, doused it with herbicides. But the distaff kept moving into what had been pasture. He thought about renting goats to eat the weeds and brush, but they were too expensive. He even considered introducing wild elk, but the bureaucratic hurdles seemed too onerous.
Then Wick and Rathmann met a rangeland ecologist named Jeff Creque. Instead of fighting against what you dislike, Creque suggested, focus on cultivating what you want. Squeeze out weeds by fostering conditions that favor grasses. Creque, who spent 25 years as an organic-pear-and-apple farmer in Northern California before earning a Ph.D. in rangeland ecology, also recommended that they bring back the cows. Grasslands and grazing animals, he pointed out, had evolved together. Unlike trees, grasses don’t shed their leaves at the end of the growing season; they depend on animals for defoliation and the recycling of nutrients. The manure and urine from grazing animals fuels healthy growth. If done right, Creque said, grazing could be restorative.

California's Sustainable Groundwater Management Act (SGMA) established a framework for sustainable, local groundwater management. SGMA requires groundwater-dependent regions to halt overdraft and bring basins into balanced levels of pumping and recharge. As a result, agricultural land retirement is on the rise in the San Joaquin Valley, California’s largest agricultural region and home to the state's highest concentration of threatened and endangered species. In this assessment, The Nature Conservancy introduces the concept of strategic land retirement and restoration, an approach which seeks to help recover San Joaquin Valley threatened and endangered species by restoring agricultural land that is suitable as habitat and under threat of retirement. The authors identify 2.5 million acres of current agricultural lands that have high potential for restoration, 14% of which was fallowed at least once during the most recent drought. 

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.
