2. 1. Geospatial Technology for Integrated Watershed and Erosion Management
Watershed Management
Watersheds (surface and groundwater)
Watershed as a system
Key Components and indicators
Hydrometeorology
Topography
Landuse
Vegetation
Soils
Geology
Agriculture, Urbanization and other activities
Watershed Degradation
Erosion
Flooding

3. 2. Geospatial Technology
Remote Sensing – systems, platforms, contemporary developments eg microsatellites and UAS.
GIS – What is it? Opportunities for natural resource management
GNSS and other allied technologies – big data and IOTs

4. 3. Challenges and the Way Forward
Institutional arrangements
RBDAs, inter-administrative nature of RBs, tools, funding, framework of operations and interventions, scope and jurisdiction, planning, inventory, monitoring etc
Uninformed management endemicity or norm
Poor mapping or use of geo-information in decision making or support

5. 3b. Challenges and the Way Forward
Tweaking institutional issues – framework, strategies, polcies, funding, political will
New geoinformation services and consultants/experts – eg drone service providers, information not data to be relevant, turn-key providers leveraging on web services for penetration and visibility/availability
PPP eg current advert to concession some RBDAs to outsourcing some of the functions of RBDAs
New educational curriculum in higher institutions to support contemporary needs and challenges – eg SDGs, climate risk assessments and mapping
