Digital data collection tools, when utilized along with mapping software applications and digital technologies such as geographic information system (GIS) and remote sensing (RS), are useful in generating information relevant to climate and environmental projects in the Philippines. Among these are the changes of the state of natural resources over time, flood risk zones and damage of natural resources assessed using normalised difference vegetation index (NDVI).

For example, the Ecosystem-Based Management and Application of Ecosystem Services Valuation in 2 River Basins (E2RB) project utilized KoBoToolbox, a digital data collection software, to conduct household surveys to establish baselines and determine flood prone zones in the project sites. These are important for land use planning and for taking appropriate action to protect people and infrastructure from loss and damage.

The E2RB project also assisted the Ilog-Hilabangan River Basin partners in assessing the damages inflicted on natural resources by Typhoon Rai (locally named Odette) in December 2021 by analysing satellite data and comparing NDVI values.

Other potential uses of digital technologies are for mapping forest degradation, tracking marine litter, planning EbA measures/ nature-based solutions to address disasters due to climate change (mitigation/adaptation strategies), modelling climate projections to help communities adapt to climate change and identifying sources of renewable marine and solar energy. The availability of satellite data from various space agencies such as the Sentinel satellites from the Copernicus of the European Space Agency and the Japan Aerospace Exploration Agency make all these possible.

The RS and GIS technologies, when paired with drones or other applications such as webGIS, can be a tool for generating accurate information on land management, for updating tenurial instruments, for crop monitoring, and for estimating yield such as those done by the GIZ projects, Responsible Land Governance in Mindanao (RLGM) and Supporting Peace and Development in Mindanao.
