Climate change may bring unexpected benefits to San Francisco Bay-Delta
“The San Francisco Bay-Delta is literally threatened from all sides: rising sea levels from the ocean, disruptions to sediment supply from upstream, and within the Bay-Delta itself, development and other land use changes have left only a tiny fraction (5%) of marshland untouched. Under climate change, coastal wetlands across the world, like the Bay-Delta, are disappearing. The rivers that feed coastal wetlands sediment which provide habitat for wildlife and form the structure of the ecosystem are transporting about a third less sediment, on average. Less sediment supply contributes to increased erosion of the ecosystem. … ” Read more from Forbes here: Climate change may bring unexpected benefits to San Francisco Bay-Delta

Audio: Almond update: irrigation research plans for future of water management
“It’s safe to assume that growers will rely more and more on artificial intelligence for their water needs as the industry pushes towards the year 2025. The Almond Board of California has developed a strategic plan for irrigation research that will support that growth. ABC’s Associate Director of Agricultural Research Sebastian Saa said that plan includes furthering actual evapotranspiration and spatial variability technology and impelling integration in the industry. Saa said ABC is accepting proposals next week for their next round of research funding to fall in line with their strategic plan.” Listen to the show from Ag Net West here: Audio: Almond update: irrigation research plans for future of water management

Devastating wildfire ‘anatomy’ explained
“Every year wildfires leave a trail of devastation across parts of the U.S. but there’s more to the science behind wildfires and their deadly “anatomy.” Wildland fires “are fires that occur on undeveloped land such as forests, prairies and shrublands; they include both wildfires and prescribed fires,” according to the United States Geological Survey. Citing 2000 to 2017 data based on Wildland Fire Management Information (WFMI), and the U.S. Forest Service Research Data Archive, the National Park Service reports that nearly 85% of wildland fires in the U.S. are caused by humans. … ” Read more from Fox News here: Devastating wildfire ‘anatomy’ explained
Think the 2020 California wildfires are bad? Experts see worse natural disasters in future

6 Western states blast Utah plan to tap Colorado River water
“Six states in the U.S. West that rely on the Colorado River to sustain cities and farms rebuked a plan to build an underground pipeline that would transport billions of gallons of water through the desert to southwest Utah. In a joint letter Tuesday, water officials from Arizona, California, Colorado, Nevada, New Mexico and Wyoming urged the U.S. government to halt the approval process for the project, which would bring water 140 miles (225 km) from Lake Powell in northern Arizona to the growing area surrounding St. George, Utah. If the approval moves forward, state water leaders wrote, “multiyear litigation” would likely be inevitable and could complicate negotiations over the future of the Colorado River, which serves 40 million people but faces threats from persistent drought and climate change that are dwindling the supply of water. … ” Read more from ABC News here: 6 Western states blast Utah plan to tap Colorado River water

What are drainage tiles and why are they an environmental issue?
“On the outside, farming may seem simple. You plant something, watch it grow, and then harvest it. Farmers wish it were so easy. But in reality, it is a complex science spanning from what variety you plant and when you plant it to what nutrients you give it. One part of that complicated process has to do with what is happening underneath the soil. That’s where drainage tiles come in. A reader named Erin asked us to help her understand how this system works and what it does. Even more, she wanted to know what implications drain tiles have on the environment and water quality. I looked through some studies and spoke with some researchers as well as agricultural officials to get their perspective. Here’s what I learned. ... ” Read more from the Indy Star here: What are drainage tiles and why are they an environmental issue?

Study of ocean salinity reveals amped-up global water cycle
“There is something in the water on planet Earth. A study published Wednesday reveals climate change has amplified the water cycle, which explains the more frequent extreme weather patterns in recent years. The water cycle is the continuous movement of water on Earth. It’s the naturally occurring pattern of rain, runoff, evaporation and repeat, but that cycle is being thrown for a loop as Earth heats up according to the study published in the Journal of Climate. Saltwater and freshwater have been evaporating at higher rates in the last 50 years while rainfall has increased, according to the study authors. … ” Read more from Courthouse News Service here: Study of ocean salinity reveals amped-up global water cycle
