Podcasts about Drylands

Drylands are vast and home to a wide array of biodiversity, while also hosting a large portion of the world's farmland, but they face continued desertification, despite many of them recently experiencing increased vegetation levels. Five million hectares (12 million acres) of drylands, an area half the size of South Korea, have been desertified due to climate change since 1980, but elevated CO2 levels are also driving a regreening of some areas, which some argue is a positive effect of pumping CO2 into the atmosphere. However, our guest on this episode says this isn't necessarily good news: remote-sensing researcher Arden Burrell describes how the CO2 fertilization effect is greening some dryland ecosystems, and why this worries scientists who say it may mask land overuse and decreased water resources.

If at any point you've been interested in water harvesting in dryland contexts, it's almost impossible that you've missed Brad Lancaster's work. His pioneering activities and projects in Tucson, AZ have propelled a movement of water wise landscaping, rainwater harvesting, and smart water reuse all around the world. While so many of the examples I've highlighted in this series relate to actions and strategies for working with the land, a huge majority of Brad's work is focused on the urban and suburban context with everything from roof water, to road and storm drain diversion, and greywater and systems.  In the last handful of episodes we've explored permaculture earthworks for water harvesting landscapes and keyline design on large scales. As a complement to those topics I got in touch with Brad Lancaster, the author Rainwater Harvesting for Drylands and Beyond, volumes one and two which have recently been re-released as expanded new editions. Brad is an expert in the field of rainwater harvesting and water management whose work I've been following for a long time. He is also a permaculture teacher, designer, consultant and co-founder of the non-profit Desert Harvesters, which teaches the public how to identify, harvest, and process many of the native-food plants people are propagating in their areas. He's also been instrumental in helping to change water management policy and government incentives in the City of Tucson to help others implement water wise catchment and reuse features on their properties.  In this interview we cover a wide range of topics from the difference between active and passive harvesting technology and reading the landscape to determine how to work with the natural surroundings, to the increasing importance for water stewardship in non-arid climates and why it's so important to connect and invest in the place you already live rather than thinking that moving to another place will solve your environmental worries.  Brad also gives great advice on home scale water harvesting and storage which are all topics that are covered extensively in his books. He's done an incredible job with the help of many experts and collaborators to compile tons of resources that are available to help you get started on his website

Agrivoltaics is the combination of agriculture and photovoltaics to create co-benefits across food, energy, and water systems. There is a lot of research being conducted around the benefits and best practices for implementation of agrivoltaics. We spoke with two experts, Dr. Greg Barron-Gafford from the University of Arizona, and Dr. Brandon Bestelmeyer, research leader at the Jornada Experimental Range, to learn more about this fairly new technology.Relevant links: Agrisolar ClearinghouseUniversity of Arizona Biosphere 2 - AgrivoltaicsJornada Experimental RangeIf you're enjoying this podcast, please consider rating us and/or leaving us a review on Apple Podcasts, Podcast Addict, or Podchaser Thanks!Follow us on Twitter @RainShinePodNever miss an episode!

Drylands encompass over 40% of terrestrial ecosystems and face significant degradation from a warming/drying climate and overuse. To combat this degradation, some restoration efforts have focused on the use of biological soil crusts (biocrusts): complex communities of cyanobacteria, algae, lichens, bryophytes, and other organisms living in association with the top millimeters of soil. We talk with Anita Antoninka, Dept. of Forestry at Northern Arizona University, about the current knowledge in biocrust restoration. These efforts effectively restore biocrusts in different ecosystems using a variety of lab and field methods, providing a useful resource for the scientific community as well as land managers.

My guest for this episode is Brad Lancaster author of the Rainwater Harvesting for Drylands and Beyond series. In this episode, Brad and I discuss the value of infiltrating water into the soil so that it becomes a resource that we invest during water-rich times and withdraw from that bank only when needed during dry times. As Brad's work includes more than just drylands the conversation also includes ideas for storing water in rich areas. Along the way we also look at several listener questions including fog harvesting, using living systems to hand wet basements, and observing to find the right match for plants suitable to wet clay soils. What I really enjoyed about this conversation was Brad's continued reference to creating and using living systems.
