Climate change solutions
We deliver game-changing environmental solutions that have a real impact for people around the globe.
Building resilient land and water systems that allow people and nature to prosper in a changing climate.
California’s Central Valley has reached a fork in the road.
By January 2020, areas where groundwater demand far outstrips supply must submit plans to bring their groundwater basins back into balance within 20 years. These plans are required by the Sustainable Groundwater Management Act, or SGMA, which was signed into law in 2014 during the state’s latest multiyear drought.
SGMA inevitably means less water for irrigating farms. Worst-case estimates forecast as much as 780,000 acres of farmland — out of more than 5 million acres of total irrigated land — will have to be taken out of production. How local decision makers and community members navigate this transition to sustainable groundwater management will significantly shape the future of the region, known as the country’s fruit and nut capital.
On one path, the valley could become a patchwork of dusty barren fields, serving a huge blow to the agriculture sector and rural communities and further impairing already poor air quality. Active farms could become surrounded by fields of invasive weeds and pests, threatening productivity.
On another path, the valley could transform into a pioneering agricultural region that not only puts food on our nation’s plates but also supports thriving wildlife habitat, outdoor recreation, soil health, groundwater recharge and flood control.
EDF is working to help communities achieve this second vision through our Central Valley Resilience Initiative, which features three key strategies: conversion of farmland into wildlife corridors, water trading and community engagement. Of course, all three strategies will require additional funding at the state, regional and local levels. (more…)
Call 2019 the year of the flood.
This spring large swaths of the nation experienced moderate to severe flooding – and the rain isn’t stopping. In California, record rainfall and snow persisted into May. In Louisiana, for the first time ever, the Army Corps of Engineers just released water through its Bonne-Carré spillway twice in a single year to avoid flooding. And hurricane season is just beginning.
The deluge of floods is hardly a coincidence.
Land-use changes and extreme weather driven by climate change are delivering a one-two punch that heightens flood risk. We’ve increased impervious surfaces – think asphalt and concrete – and at the same time we’ve removed wetlands, prairies and forests, which can absorb water and slow runoff. We’ve also built hard infrastructure such as bridges, urban and agriculture drainage networks, and even, ironically, flood “protection” projects that often alter watersheds, floodplains and stream hydrology and increase the severity of floods.
So how do we better protect critical infrastructure and communities in the face of increased flooding? (more…)
With the start of another Atlantic hurricane season, coastal residents from Texas to New York should hope for the best and prepare for the worst. While the current prediction is for a close-to-normal 2019, prior years have demonstrated that it only takes one storm to bring widespread devastation.
In 2018, Hurricane Michael became the first Category 5 storm to hit the continental U.S. since Hurricane Andrew in 1992. Communities are still recovering from the unprecedented 2017 Atlantic Hurricane season, which caused $282 billion in damages, including $92.2 billion in Puerto Rico and the U.S. Virgin Islands from Maria and $128.8 billion from Harvey in Texas.
Through this devastation, we have learned several important lessons about how to better prepare for and react to storms to reduce damages and hasten recovery. (more…)
The U.S. Fish and Wildlife Service delayed its decision about whether to list the monarch butterfly as endangered or threatened until December 2020 — 18 months later than the original deadline of June 2019.
Because the original deadline resulted from a litigation settlement, this extension had to be approved by federal courts and the other parties to the litigation. While certainty about a regulatory decision of this scope is always beneficial, this mutually agreed upon delay creates an opportunity that shouldn’t be missed.
Here’s what farmers, ranchers and their partners need to know about how the delay will impact monarch conservation efforts. (more…)
My upbringing drew me to work in coastal hazards. Though I work on coastal resilience in Louisiana, I spent much time throughout my childhood and adult life in Odisha, a state with a 300-mile coastline along the Bay of Bengal. Odisha is part of the bay’s infamous cyclonic zone that stretches across the Bangladeshi lowlands, and its coastline has been subjected to devastating storms and floods intensified by the effects of global warming and sea level rise.

In pulling the plug on the twin Delta tunnels and scaling back California’s high-speed rail line, Gov. Newsom broke from his predecessor, who fiercely defended the projects as part of his climate agenda.
But that doesn’t mean Newsom can’t build on Jerry Brown’s strong climate legacy. He can, all while charting a different legacy for himself.
While it may be unfair to reduce Brown’s climate achievements to a few bullet points, two themes often appeared in his initiatives: prioritizing policies to slash greenhouse gas emissions, and capitalizing on the state’s ability to impose mandates.
With the U.S.-China trade war and flooding in the Midwest continuing to make headlines, national attention is focused on the increasing economic challenges facing farmers and their families.
After years of weak commodity prices, these financial stresses are adding up. In the Corn Belt, farm bankruptcies are at the highest level in over a decade.
Given this challenging economic outlook, some might assume that farmers will abandon conservation efforts and focus exclusively on their finances. However, many of the financial best practices cited by farmers and encouraged by farm financial advisers are the very same principles that can help farmers continue to improve environmental outcomes. Here are four examples. (more…)
Earlier this month, the U.S. Army Corps of Engineers opened the Bonnet Carré Spillway north of New Orleans for the second time this year to relieve pressure on the Mississippi River levees and protect communities in south Louisiana from catastrophic flooding.
It was the first time in the structure’s nearly century-old existence that it had been opened twice in the same year. When the Corps opened the spillway in February, it was the first opening in back-to-back years.

Corps Maj. Gen. Richard Kaiser recognized this unprecedented occurrence in response to the wettest period in 124 years, saying, “This is not business as usual.” What was designed as an emergency flood control system has increasingly become a default safety valve, as climate change and increased precipitation throughout the Mississippi River Valley only further stress the system.
This is a sign that we need to re-think how we manage our rivers and revisit operations of a system designed nearly a century ago. (more…)

While Colorado River surface water supplies have dominated news headlines recently, Arizona communities face another important water challenge: rapidly declining groundwater levels.
Arizona relies on groundwater for about 40% of its water supply, yet groundwater resources outside of the state’s biggest urban areas are largely unprotected and unregulated, posing a risk to long-term economic growth, community resilience and healthy flowing rivers.
HB 2467, a bill that was signed by Gov. Doug Ducey on May 22, takes an important step forward to address groundwater challenges in Mohave and La Paz counties.
Mohave County is in northwest Arizona and includes western portions of the Grand Canyon and the city of Kingman on historic Route 66. La Paz County is just south of Mohave and includes the Interstate 10 corridor, part of the Kofa National Wildlife Refuge and important perennial streams. In recent years, residential and other small wells have increasingly seen water levels dropping as more large-capacity wells are drilled for commercial agricultural operations moving into the region, often from outside Arizona.
Jim Maciel knows about the challenges of providing safe and affordable drinking in California all too well.
His experience serving as director of a small water district highlights why state legislators’ approval of $140 million in new annual funding to provide safe, affordable water to all Californians is long overdue.
Jim is one of about 37 water leaders who I have had the privilege of meeting through the Leadership Institute, a training program created by Rural Community Assistance Corporation and expanded by Environmental Defense Fund and Self Help Enterprises. Many of these leaders are stewards of small community water systems, which serve 10,000 or fewer customers. Their small size is a big part of their challenge.
