Towards a web-based decision system for Philippine lakes with UAV imaging, water quality wireless network sensing and stakeholder participation

摘要

There is a critical need for modern lake resource management in the Philippines because of climate change, disasters, intensive aquaculture and poor waste-management practices. To this end, we have deployed floating field-servers in Lake Palakpakin, one of the Seven Lakes in San Pablo City, Philippines monitoring conductivity, temperature, dissolved oxygen and turbidity at two depths-0.5 and 2.5 meters for over a year, with web access to data by SMS. We also have deployed UAVs to image the lake area to quantify fish cage density, water hyacinth coverage and disaster damage. The local fisher folk report daily lake activities-fish-feeding, harvesting, and fish-kill events by taking pictures and other measured data using smartphone applications. We describe how these measurements are being integrated into a web-based decision-support system.
