I explore whether and how communities (largely part of community forest user groups in the buffer zone of Chitwan National Park in Chitwan, Nepal) collectively act in the face of Mikania invasion.

Over one third of modern irrigated fields, however, show signs of serious soil degradation, including salinization and waterlogging, which threaten the productivity of these fields and the world's food supply. Surprisingly, little ecological data on agricultural soils have been collected to understand and address these problems. How, then, can expanding and intensifying modern irrigation systems remain agriculturally productive for the long-term? …
