JRN scientists have created tools and programs to make scientific results readily available to a variety of stakeholders, including land managers, scientists and teachers. Outputs include web-based access to scientific data, methods to monitor changes in soils and vegetation around the world, and training for K-12 students and teachers.
JRN scientists discovered that variability in ecosystem responses in both time and space is more characteristic of drylands than average conditions. New research approaches provide insights into old problems, including inconsistent responses through time, persistent and variable patterns in space, and emergent behavior across scales.
Desertification is a global problem that reduces plant productivity, biodiversity, air and soil quality, and water availability. JRN scientists developed an integrated understanding of consequences of desertification in arid ecosystems, including loss of ecosystem services
JRN scientists discovered the mechanisms by which grasslands, shrublands, and other ecosystems cross ‘tipping points,’ or thresholds in which dramatic and rapid changes can occur. A better understanding of these thresholds is paramount to management and protection of grasslands and other ecosystems.
Jornada studies initiated in the early 1900s reveal how the change from productive, diverse perennial grasses to shrublands on degraded soils is difficult, but not impossible, to reverse. With over 1.25 billion people living in dryland areas, it is critical to understand the restoration potential of degraded systems.
