The central hypothesis for the IML-CZO is that, through human modification, the critical zone of IMLs has passed a tipping point (or threshold) and has changed from being a transformer of material flux, with high nutrient, water, and sediment storage, to being a transporter. This change threatens the resilience of the landscape to accommodate future impacts associated with ongoing human activity, including climate change and bioenergy crop production. The vulnerability of the IMLs increases as these human activities intensify, compromising the sustainability of key critical-zone services on which ecological systems and human populations depend. Understanding and quantifying shifts in the response of the critical zone to human development remains a challenge, and current assessments are at best qualitative.
The IML-CZO will first examine how:
Researchers will next capture the connectivity of contemporary hydrological, geomorphological, and biogeochemical processes along different flow paths by quantifying the stores and residence times of water, SOM, DOC, and sediment.
