This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 642088 SWOS Project - Ecosystem mapping and flood regulation capacity in the Guadalhorce basin - Symposium S i on Connectivity C ti it in i Mediterranean Rivers M l Malaga, 3 Sept S t 2019 • Christoph Schröder, University of Malaga Project context H2020 call Making Earth Observation and Monitoring Data usable for ecosystem modelling and services Objective j Provide an earth observation based mapping and monitoring service for wetlands 2 SWOS is a service • Biodiversity hotspot delivering a large set of ecosystem services • One of the ecosystems most affected ff t d by b degradation. d d ti • Insufficient methods and tools to evaluate and monitor its condition. 3 Sentinel-3 MERIS (Envisat) Sentinel-1 Landsat- 8 Landsat TM Landsat MMS Landsat ETM+ MODIS Sentinel-2 4 Landsat and S2 for wetland monitoring Monitoring short term changes and wetland characteristics (Fuente de Piedra, Spain) 5 Radar data for wetland monitoring 6 SWOS is a service 7 Service components: Map & Indicator production From satellite images to maps and indicators From Satellite Images to Segment  From Segments to Maps    From Maps to Indicators 8 Service components: Mapping products LULC Change (short- and long-term) Land Surface Temp.

Based on the capacity of ecosystems (e.g. forests, wetlands) to regulate floods tthrough oug ttheir e functional u ct o a retention ete t o capac capacity, ty, flood ood regulation egu at o ecosyste ecosystem se service ce supply (or service production) and demand (or the benefit of the service) are calculated. 13 Flood regulation capacity in the Guadalhorce: Conceptual approach An indicator on flood regulation as an ecosystem service should take into account three key variables 14 Flood regulation capacity in the Guadalhorce: Conceptual approach Flood regulation capacity in the Guadalhorce: Context A problem with decades of history • In the basin of the river Guadalhorce, especially in its mouth, there has been a decline in natural capacity of flood regulation. • However, the most important factor that caused the flooding problems has been the significant increase in exposure to risk, which has led to increased demand for the service. Year Year Year Year 1917 1989 2012 2015 16 Flood regulation capacity in the Guadalhorce: Results Since the late 70s to the present there has been a great urban development in the floodplain, especially at the mouth of the river Landsat 5 TM+, April 1985 Sentinel 2A, March 2016 17 Flood regulation capacity in the Guadalhorce: Results LULC cover between 1956 and 2011 in the area at risk of flooding Until the 70s, the area was largely rural, the land was used for agriculture Year 1956 Year 1977 18 Flood regulation capacity in the Guadalhorce: Results The city of Malaga and nearby towns extend along the river floodplain Year 1984 Year 2011 19 Flood regulation capacity in the Guadalhorce: Results 53% of artificial surface under risk are industrial and residential These are the main areas demanding the flood regulation service Urban class % Airport 8,70 Industrial, technical infrastructure 30,50 Recreational and commercial 9,40 Urban fabric, Residential Areas 22,79 Transport infrastructure 28,61 20 Flood regulation capacity in the Guadalhorce: Results Flood regulation capacity in the Guadalhorce: Results 22 Flood regulation capacity in the Guadalhorce: Results 23 Thanks www.swos--service.eu www.swos christoph.schroder@uma.es
