About DRIP

Why DRIP?

Dams in rivers provide hydro-power energy, secure water for irrigation and consumption, and help protecting against floods. But dams also disrupt river flow regimes and connectivity, with negative consequences for biodiversity and ecosystem functioning. To better understand the benefits and trade-offs of dams worldwide, we need accurate information on the number of dams and their locations. However, this information is scarce and scattered, and compiling a globally consistent and accurate dam database is a daunting task. We took up this challenge with the dam and reservoir inventory project (DRIP): a crowd-sourcing project to compile a global atlas of dams. So we need your help! See here how you can contribute to DRIP.

The GLOBIO project

The database resulting from DRIP will be used to improve the GLOBIO model: a global model to quantify current and future terrestrial and freshwater biodiversity. The information of dam locations in DRIP will be used to calculate the degree of river regulation and fragmentation, which in turn is input to quantify effects on biodiversity and ecosystem functioning. If you want to read more about the GLOBIO model, see here.

PBL Netherlands Environmental Assessment Agency

DRIP and GLOBIO are commissioned by PBL Netherlands Environmental Assessment Agency. PBL is the national institute for strategic policy analysis related to the environment, nature and spatial planning. These analyses include outlook studies, scenario analyses and evaluations, all aimed to improve the quality of political decision making regarding our environment. More information on PBL can be found here.

The DRIP website

The DRIP website was developed by gissense.com and uses ESRI ArcGIS Online webmapping technology and the ESRI imagery basemap for barrier recognition.
