The development of technologies for environmental informatics is needed to find new indicators for more precise
and realistic monitoring and assessment [33]. For the purpose of improving IWRM with regards to balancing water
supply and demand, environmental informatics is important to find indicators that can help with cost-effective
solutions. For example, modeling indicators can help us to understand the short-term and long-term dynamics of
mining pollutant behavior in order to find out the casual effect and cost-benefit relationship for immediate national
policy planning in Peru [34]. Geographic informatics system GIS, could be useful to follow the agricultural chemical and organic waste run-off in the Atlantic slope and its consequences on the Pacific slope since they are
part of the same aquatic ecosystem. Remote sensing RScan help us to find out if and how climate change in Peru is
impacting the melting Andes glaciers and how to mitigate this problem.
