This fourth edition of the publication Environmental Law and Policy in Namibia - Towards Making Africa the Tree of Life comes at a timely moment both nationally and internationally as the country is tackling diverse and numerous environmental and developmental challenges while the world has come together at the 26th UN Climate Change Conference of the Parties (COP26) in Glasgow on 31 October - 13 November 2021 to accelerate action towards the goals of the Paris Agreement and the UN Framework Convention on Climate Change. The previous three editions of this book were published in 2011, 2013 and 2016, respectively, and all three were a great success. We therefore have sustained our commitment to this work and funded this fourth revised and expanded edition. The Namibian Government has taken the lead to recognise the impact of the population with its economic activities on the country's natural environment and has also taken the initiative to adopt and domesticate ethical and humane legislation and policies to inclusively undertake, manage and monitor environmental management.
