This issue of Unasylva will be dedicated to the restoration of degraded forest ecosystems in the Mediterranean region. Ten years after the last issue on Mediterranean forests, this volume will provide a status of Mediterranean forest resources with a specific focus on restoration efforts, recent developments, and opportunities to achieve regional and global pledges. It will also highlight Mediterranean restoration efforts that the UN Decade wants to promote on a global scale.

he Seventh Mediterranean Forest Week, entitled “Forest and Ecosystem Restoration for the next Mediterranean Generations", took place from 21 to 25 March 2022 in Antalya, Türkiye. The Mediterranean Forest Week gathered more than 150 public and private sector representatives, national and local governments, technical and scientific organizations, forestry experts and managers, environmental organizations, non-governmental organizations (NGOs), young professionals, media, scientists and academics, and stakeholders from forest-related sectors coming from 14 countries, all of which contribute in setting up a shared vision for the Mediterranean forests in this event.

This book has been published by Allenvi (French National Alliance for Environmental Research) to coincide with the 22nd Conference of Parties to the United Nations Framework Convention on Climate Change (COP22) in Marrakesh. It is the outcome of work by academic researchers on both sides of the Mediterranean and provides a remarkable scientific review of the mechanisms of climate change and its impacts on the environment, the economy, health and Mediterranean societies. It will also be valuable in developing responses that draw on “scientific evidence” to address the issues of adaptation, resource conservation, solutions and risk prevention. Reflecting the full complexity of the Mediterranean environment, the book is a major scientific contribution to the climate issue, where various scientific considerations converge to break down the boundaries between disciplines.

This Unasylva issue aims at showcasing forest and landscape restoration (FLR) opportunities and recent developments that have the power to upscale restoration, in order to achieving the Bonn Challenge pledge and other national and international commitments (Sustainable Development Goals (SDGs), the Convention for Biological Diversity (CBD) Post-2020 Agenda, the United Nations Convention to Combat Desertification (UNCCD) Land Degradation Neutrality, Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC)) and addressing the needs of the UN Decade 2021-2030 on Ecosystem Restoration. The content adresses thematics of relevance to various audiences: i) flagship restoration initiatives that differ from the so-called “business-as-usual” as they channel more funds, better empower local stakeholders and provide enhanced technical assistance through partners’ coalitions; ii) technical advances that can spread FLR and have a huge potential to be mainstreamed for different reasons (low cost, adaptability, relevance to many ecosystems and contexts, ease of implementation…); iii) the enabling factors for restoration, i.e. coordination, policy environment, resources, knowledge and capacities, as these are the enabling conditions for action to take place on the ground.

Capitalizing on forty years of intensive ecological studies, this anthology presents a collection of widely dispersed major publications on theoretical and practical Mediterranean, global environmental and landscape issues. Each chapter features a comprehensive study of ecological and landscape issues, synthesized in the introduction, and woven with autobiographical experiences. The concluding chapter calls for a transdisciplinary shift in all environmental scientific fields and particularly in landscape and restoration ecology, to cope with the complex, closely interwoven ecological, socio-economical, political and cultural crises facing human society during the present crucial transition from the industrial to the post-industrial, global information age. Updating and broadening the scope of the groundbreaking Springer book on Landscape Theory and Applications by the author and Lieberman (1994), this is a unique transdisciplinary attempt based on advanced systems complexity theories, which link the natural and human sciences.

The Mediterranean region has more than 25 million hectares of Mediterranean forests and about 50 million hectares of other Mediterranean wooded lands. They make crucial contributions to rural development, poverty alleviation, food security, as well as, the agricultural, water, tourism, and energy sectors. Changes in climate, societies, and lifestyles to create appropriate financial incentives and tools. in the Mediterranean region could have serious negative consequences for forests, with the potential to lead to the loss or diminution of those contributions and to a wide range of economic, social and environmental problems. In the future, Mediterranean forests will support agriculture and human wellbeing. It is therefore crucial to improve policies, practices, and to promote sustainable management to provide social and economic benefits as well as to increase the resilience of ecosystems and societies. This new edition of the State of Mediterranean Forests aims to demonstrate the importance of Mediterranean forests to implementing solutions to tackle global issues such as climate change and population increase. Part 1: The Mediterranean landscape: importance and threats. Despite the important natural capital provided by Mediterranean forests, they are under threats from climate change and population increase and other subsidiary drivers of forest degradation. Part 2: Mediterranean forest-based solutions. Forests and landscape restoration, adaptation of forests and adaptation using forests, climate change mitigation, and conserving biodiversity are additional and complementary approaches to address the drivers of forest degradation to the benefit of populations and the environment. Part 3: Creating an enabling environment to scale up solutions. To scale up and replicate forest-based solutions, there is a need to change the way we see the role of forests in the economy, to put in place relevant policies, more widespread participatory approaches, to recognize the economic value of the goods and services provided by forests and, ultimately, to create appropriate financial incentives and tools.
