Nationwide analysis of riparian buffer zone between agricultural land and surface waters within the realm of the NAP
Project
Project code: JKI-SF-08-1175
Contract period: 01.01.2011
- 31.12.2019
Purpose of research: Inventory & Assessment
Surface waters are especially sensitive to pesticides exposure. Directive 2009/128/EC commits EU Member States (MS) to take appropriate measures to avoid pollution of surface water, such as the establishment of buffer and safeguard zones, planting hedges along surface waters etc. Before taking such actions in an efficient and appropriate way the status-quo of riparian zone between agricultural land and surface waters need to be assessed nation-wide. As there is no spatial database in Germany that provides such information, an approach was developed to give a most precise estimate on community level. The approach is based on spatial data of the land parcel information system (LPIS) for a precise description of the agricultural land. The database is part of the Integrated Administration and Control system and exists in all MS. Information on the surface water network stem from the German authoritative topographic database ATKIS. For the assessment a zone of 10m directly adjacent to the top of the water body embankment is analyzed in 1m steps. With GIS methods both datasets are spatially related. Although the dataset stem from different data models a good degree of consistency is achieved as both datasets are derived from aerial orthophotos.
