Example 1 • Problem with forest regeneration in one fire-affected location in California
Example 2 • Problem with agricultural productivity and effects on neighboring forests related to their solution response.
Mexico • Soils are very alkaline • Crops have low productivity • Total analysis of soils do not show deficiency but leaf analysis show P deficiency – why??? • Available P shows deficiency • Farmers are very poor in this Oaxaca region of Mexico • How can they increase crop productivity?
Example 3 • Problem with erosion in Iceland due to over-harvesting of birch and also grazing by sheep and one of their solutions.
Before Viking Settlement 75% vegetated, 25% mountain birch Today less than 25% vegetated, 1% mountain birch
