In developing and low income countries, there is a lack of efficient, dense and modern monitoring systems due to high costs of hardware and software components, low access to replacements parts and limited local capacity. In addition, conventional systems are usually characterized by low interoperability and scarce metadata, mainly because of the closed and proprietary nature of the components.

The 4onse project studies non-conventional monitoring systems fully based on open technologies (hardware, software, data and standards) for the management of resources and natural hazards in developing countries.
