Summary
The Cherio River basin is located in the eastern part of Bergamo province, Lombardy region. It extends from the pre-alpine reliefs to the irrigated plain area, down to the confluence of Cherio River into Oglio River. The catchment area is about 153 km2, broken down mainly into forest (42%) and agricultural (39%) land. The territory is vulnerable to overflows and flooding events, which requires constant reclamation activities. Moreover, the increasing water withdrawals from Cherio River for industrial and agricultural purposes compromises the possibility to ensure environmental flows, especially during summer and drought periods. Pollution from nitrogen, phosphorus and wastewaters finally contributes to deteriorate the overall water quality.
OPTAIN seeks the involvement of local actors to identify strategies and solutions for an efficient water management, aimed at ensuring quali-quantitative standards to safeguard natural and aquatic habitats and to support an agricultural system deeply dependent on water resources.

Vegetation class
The case study area is mostly covered with forest vegetation in its upper part, while cropland dominates the lower (plain) part of the basin. Most of potential NSWRM are implemented on cropland or in marginal areas along watercourses, while terraces are concentrated in hill and mountain areas currently covered with forest/woodlands because they are largely abandoned and not well maintained. Vegetation cover changes thus depend on the type of NSWRM activated: it does not changes in case of drought-resistant crops; it changes to grassland in case of river restoration (i.e. wetlands) and to grass/shrubs/deciduous trees in case of riparian buffers, and assumed to change to permanent crops in the case of terraces. In case a pond is implemented, arable land changes to a pond

Policy challenges requirements
There has been an increase in severe droughts and extreme rainfall events, leading to floods in both urban and agricultural areas. The area is also suffering from pollution of both urban and agricultural origin.

Overall impact
Hopefully, the overall results of OPTAIN can serve as a decision support tool to stimualte the (wider) implementation of measures, overcoming bottlenecks and current weaknesses in this direction, and to contribute in drafting/providing policy guidelines.
