Water is critical to sustain life, agricultural production and preservation of natural ecosystems such as wetlands. Understanding the hydrologic cycle, soil-water interactions, and how anthropogenic activities influence water balance and quality is essential for sustainable water resource management. Wetland management generally involves activities that can be conducted within, and around wetlands, both natural and man-made (constructed), to protect, restore, manipulate, or provide for their functions and values. To reduce wetland losses, improve and preserve soil and water quality of wetlands requires knowledge on wetland biogeochemistry. Assessment of ecological indicators is critical to optimize management of wetland ecosystems.
