The Jornada Basin and Mongolian LTER program both focus on desertification processes. Due to past contacts and an informal meeting with Dr. Chadraa (President of the Mongolian Academy of Sciences) at the LTER ASM, Jornada Basin scientists were invited by representatives of the Mongolian and Swiss governments to meet in Ulan Baatar with scientists and stakeholders in October 2006. This visit revealed the high value placed by these governments on understanding desertification processes and developing science-based strategies to mitigate its effects.
Long term data are invaluable in both understanding the properties and dynamics of ecological systems as well as in forecasting future system dynamics. Trends in long term data are critical to the ability to: (1) distinguish temporal variability from directional changes, (2) relate changes in response variables to changes in drivers or other response variables, (3) relate changes in ecological dynamics with changes in socio-economic systems, (4) forecast future dynamics under changing climatic, disturbance, and landuse.
