The participatory process itself

M&E will allow us, for instance, identifying who were the participants involved, what methods were used, who was mobilized and at what moment

Its impacts

M&E will allow us to know if we are well engaged to reach our objectives, what effects the process had on the participants or the environment
You maybe heard of environmental impacts evaluation

Its context of implementation

M&E allows us identifying the starting point, who are the different actors, what knowledge they have about water, what are their relations etc.
It will also allow us identifying the elements from the environment that could have impacts directly on the process and its results (for instance floods, political change, migrations…)
