This ninth edition of the Yearbook on Peace Processes analyses conflicts in which negotiations are being held to reach a peace agreement, regardless of whether these negotiations are formalised, are in the exploratory phase, are faring well or, to the contrary, are stalled or in the midst of crisis. It also analyses some cases in which negotiations or explorations are partial; that is, they do not include all the armed groups present in the country (such as the case of India, for example). The majority of the negotiations refer to armed conflicts, but we also analyse quite a few contexts in which, despite the fact that there are no considerable armed clashes today, the parties have not reached a permanent agreement that would put an end to the hostilities and conflicts still pending. In that sense, the negotiations make sense in an effort to fend off the start or resurgence of new armed clashes.
