Climate Water Project

Brock Dolman is a conservation biologist and permaculture teacher who coined the phrase "Slow it, sink it, spread it" and helped co-found the Occidental Arts and Ecology Center and the Water Institute https://oaec.org/our-work/projects-and-partnerships/water-institute/

His organizations work helped bring back the beaver in California, and has helped communties restore the water cycle in their neighborhoods. The template for neighborhood watershed restoration is here https://oaec.org/publications/basins-relations-citizens-guide-2018/

Forests evapotranspire water vapor. When that vapor condenses to form clouds it creates a lessening of pressure which can then attract more moisture from the ocean. Anastasia Makarieva and Victor Gorshov discovered this effect called the Biotic Pump

An ambitious project to regreen the Sinai desert in Egypt is underway. It involves 1) restoring Lake Bardawil at the northern tip of the Sinai 2) turning the sediment from the lake into soil which is then used to jump start the regreening process in the desert. Creating temporary ecosystems in geodesic domes that catalyse the ecosuccession process 3) a shift in the rain and wind patterns that result from the regreening

Minni Jain is the founder of the Flow Partnership, an organization that has helped thousands of communities in India and Britain protect themselves against floods and droughts, by the use of simple watercatchment structures that can slow, sink, and spread the rainfall as it comes down.

Professor Helen Dahlke, of the University of California of Davis, has been leading the (re)charge to replenish California’s groundwaters. She has teamed up with farmers, to guide the excess water from the winter rains to flood farms, thus creating temporary wetlands. Over days and weeks, that water then sinks down to replenish the aquifers.

In this podcast Helen Dahlke shares about her research, the groundwater situation in California, the quest to replenish its aquifers, the droughts and intermittent large rains, the wetlands and floods, and the interdiscplinary efforts to bring back nature-based solutions to our water needs all over the world.

Francina Dominguez, a hydroclimatologist at the University of Illinois has been figuring out where our rain comes from. She has been tracking water as it moves across our continents. The process of moisture hopping, or moisture recycling (also known as the small water cycle in other circles), is the movement of water from air to land to air to land and so on - rain falls to the land, and then evapotranspires back up to form rain again.

She studied the droughts in the US Midwest in 2012, and found that the droughts there were related to the drought in California. Rains hop inland from California to the Midwest. When there is less water vapor in California, there will be a less moisture hopping inland. [1]

Francina Dominguez has also been researching the behavior of rain in South America. Having grown up in Colombia, which is home to part of the Amazon rainforest, she was motivated to stop it from being chopped down. When she became a hydroclimatologist, she used climate models to study the effect Amazonian deforestation would have on the water cycle.

Her simulations found something quite surprising.

Climate modelers do not always know what effects will emerge out of their models. They put in various equations and various parameters into their models, and then they wait for it to emerge a result. When Francina Dominguez modeled deforestration in the Amazon she was expecting to find that moisture recycling (aka the small water cycle) would decrease as forests were chopped down. What she instead found, to her surprise, was that the moisture recycling stayed the same, and it was the wind that increased. When the trees were cut down, the wind blew in faster which made it harder for the water vapor molecules to coalesce to form rain. Deforestation led to wind increase, and the wind increase led to rain reduction. Or to state it another way as a maxim - forests makes less wind, less wind makes more rain. [2,3,4,5,6]

Francina Dominguez has also studied the interaction of groundwater and climate. At first glance it might seem that groundwater would not affect drought and rainfall patterns. After all groundwater is underground and not touching the air. But water is a complex systems phenomena, understanding one part often requires understanding how all the parts fit together. What Francina found in her models was that groundwater would have a significant effect on rain, because it was being brought up by the root systems of the vegetation, and then would evapotranspire into the air to increase the moisture content in the air. Groundwater levels thus affect drought and rainfall patterns. [7,8]

In this podcast I interview Dr. Elizabeth Dougherty, executive director of WhollyH20. She was instrumental in helping get California to pass its greywater laws. She did this by bring different demographics together - the hippies who knew about what to do with water, with the Stanford engineers who were happy to learn about these methods, and the government officials who could implement the new water laws that allowed these new ways of working with water. She talks about getting Brock Dolman, now a water legend who runs the Water Institute at the Occidental Arts and Ecology Center, who back then was a long haired bare-foot hippie, to put on suits in order to be heard properly by formal administrators and public utilities workers.

Elizabeth got her PhD in anthropology, and is interested in peoples relationship with the water cycles. Her organization has more recently worked with getting communities to connect with their watersheds, and talk about the stories of water in their neighborhoods, with one common, usually largely unknown, story being that neighborhoods have paved over their creeks. Telling these stories can help get a process called “daylighting” to bring these creeks back to the surface. In getting communities interested about their watershed, they learn about the various aspects of the water cycle, and are more willing to get water projects activated.

Nik Bertulis is a permaculture water educator, a designer of integrated water systems, implementing greywater, rainwater, stormwater and wetland systems. He cofounded Dig.coop a water conservation systems cooperative. He has designed many innovative water solutions for our environment.

We talk about the importance of closing the nutrient cycles in our environment. What our society considers waste, our pee, our poo, our sewage, can be useful nutrients for the vegetation and soil. The distribution of pee and poo of animals moving around support the functioning of our ecosystems. Nik discusses how we can clean our sewage with nature’s natural biology and wetlands rather than with synthetic chemicals.
