Despite covering almost a third of the globe, forests do not enjoy the protection of a singular global legal convention. Instead, International Forest Law is a complex ecosystem in its own right. This book sets out to examine this complexity by analyzing forest-related Multilateral Environmental Agreements (MEAs) and how the decisions of the various corresponding Conferences of the Parties (COPs) may promote regime interaction in this field of law. Through an in-depth analysis of more than 60 decisions and resolutions of such COPs, Yilly Pacheco discusses how secondary law-making activity in forest-related MEAs may be strengthened and used to fill the gaps in International Forest Law.
