Biosphere Processes 101

Basic biosphere processes such as water cycle, carbon cycle, both driven by solar energy, and which do much more work than industrial energy.

Keith Berns (Greencover Seed) on rebuilding the nation's soils

From the 3rd Southern Soil Health Conference. What leaders are needed, what workers are needed, and what tools are needed to rebuild the nation's soils.

Walter Jehne: Restoring water cycles to naturally cool climate

Walter Jehne, former CSIRO Climate Scientist and Microbiologist, founder of Healthy Soils Australia, explains the role of water in climate change and climate mitigation at an intensive workshop at Lake Morey Resort in Vermont, USA (November 2016). Water is the largest greenhouse gas and yet climate models have not fully included it because 1) it is considered too hard to model and 2) it is not considered possible for humans to influence. Jehne shows how we CAN work with hydrological cycles and the soil sponge to naturally, safely cool the climate, but only if we get started right away.

Learning Resources for Schools and Communities

Welcome! Our new learning resources include step-by-step instructions for facilitators to lead groups of participants through activities to engage students, farmers, policy makers and others in seeing new possibilities related to soil health, water and carbon cycles, and systems-based land management. (Check back often as we are loading new versions every few weeks.) Our activities are aligned with Next Generation Science Standards, Common Core State Standards, and Agricultural Education Standards for ease of use in U.S. schools, but can be used and adapted by anyone interested.

Rancher-to-rancher day at Sierra Foothill Conservancy near Prather, California

The Rancher-to-Rancher day at Table Mountain with Sierra Foothill Conservancy on March 19, 2016 was one of the best. Kent Reeves had arranged this with Billy Freeman, their cattle and grazing manager. We had great weather for an outdoor day, and the place was lush and beautiful with lots of grass and flowers.

Shifting soil paradigms

This 3-minute video is the intro to a series of videos on soil health. By Buz Kloot who works in South Carolina.

Soil aggregates and infiltration: an analogy

Using flour, bread, and water, Emaline shows how rainwater and flooding affect unaggregated (poorly structured) soils vs. aggregated (living) soils. This is part of the Climate, Water, Soil & Hope project created by Didi Pershouse of the Soil Carbon Coalition. Our goal is to grow and support leaders who know how to collaborate with the power of biological work. To donate to our project, see button on this page, or for more information contact

Water cycle

Much conventional thinking about the environment tends to separate "parts" of the same whole. In dealing with water problems, for example, we tend to focus on symptoms -- such as flooding, erosion, and riparian conditions -- rather than causes, which are almost always related to the function of the water cycle.

Power, work, and energy

Power, work, and energy are not things -- we cannot see them directly, but only as actions or processes, by what happens as a result, such as how high a thrown stone gets before it begins to fall. But we can know them and even measure them.

Is it possible to measure the work done by plants, by photosynthesis? How?

Can you find estimates of total global photosynthesis, expressed in watts or horsepower or some other measure? What kinds of observations and measurements are these estimates based on?
