Sprouting Trees From the Underground Forest — A Simple Way to Fight Desertification and Climate Change
Beginning in Niger in the 1980s, Tony Rinaudo, an African aid missionary, began working with farmers to develop a new approach to reforesting degraded landscape. The practice he developed involved selective pruning of shrub shoots to a main stem, which was then pruned of its lower leaves and branches. Within a few years, new woodlands were growing.
The upper Delaware River Basin System is one of the largest water supply systems for the city of New York. Today our understanding and management of these reservoir systems is based on the short historical records of data, which are limited. Scientists need to find a way to look further into the past. One of the answers lies in tree rings.
