Towards A Better Understanding of Forest-Health Relations

The International Day of Forests (IDF) on 21 March https://www.fao.org/international-day-of-forests/en/ is celebrated to raise awareness of the importance of all types of forests. Each year the Collaborative Partnership on Forests (CPF https://www.fao.org/collaborative-partnership-on-forests/en) chooses a theme for the day. In 2023 the theme was 'Forests and Health'.

Global Assessment on Forests and Human Health Launched on 21 March

IUFRO World Series Vol. 41

In line with the theme of IDF 2023, IUFRO celebrated the International Day of Forests by launching the most comprehensive global assessment to date of the links between forests and human health.

Read the IISD-ENB Coverage: 

The global scientific evidence of the multiple types of benefits that forests, trees and green spaces have on human health has been assessed by an international and interdisciplinary team of scientists.

The outcome is a major peer-reviewed report titled "Forests and Trees for Human Health:  Pathways, Impacts, Challenges and Response Options" prepared by the Global Forest Expert Panels (GFEP) Programme of IUFRO, and edited by Cecil Konijnendijk, Dikshya Devkota, Stephanie Mansourian and Christoph Wildburger.

The following key messages are highlighted:

  • Forests, trees and green spaces impact human health across all life stages.
  • Positive health outcomes of forests, trees and green spaces significantly outweigh negative ones.
  • The health outcomes of forests are the result of several pathways that are dependent on context and individual lifestyles.
  • Forest-health relations need to be considered when dealing with global crises.
  • Integrative and cross-sectoral approaches need to be adopted to improve the forest-health link.

The report emphasizes the important contribution of forests and trees to the United Nations' 2030 Agenda for Sustainable Development and its goals, particularly Goal 3 (SDG 3), which aims to "ensure healthy lives and promote well-being for all at all ages."

Global Reviews on Forest Management and Provision of Hydrological Functions

Presented on 22 March, World Water Day

World Water Day 2023 http://www.worldwoodday.org/2023/ emphasized the need to accelerate change to solve the water and sanitation crisis. A new publication launched on WWD 2023 highlights the critical role that forests play in sustaining water resources and the importance of managing forests also with a view to water.

This Special Issue of Forest Ecology & Management edited by Xiaohua (Adam) Wei, Richard Harper and Shirong Liu showcases global reviews on the effects of forestry on hydrological functions. The nine papers in this Special issue were developed by members of the IUFRO Task Force Forests and Water Interactions in a Changing Environment:  https://www.iufro.org/science/task-forces/forests-water-interaction-changing-environment/

Forests not only play an important role in shaping the terrestrial environment but are also critical for sustaining water resources and aquatic ecosystem functions. However, forests and their connected aquatic ecosystems are undergoing significant change mainly due to increased large-scale natural forest disturbances (e.g., forest fires, insect infestation), timber harvesting and climate change impacts such as drought and increased temperature.

The purpose of this special issue is thus to provide various syntheses through a systematic array of topics related to forest management practices and their relations to hydrological processes and functions at the global scale. The conclusions from these global review articles are expected to greatly improve practical planning processes and on-ground forest practices that enhance protection and provision of water and water-related services.

To promote this special issue world-wide, the Journal kindly provides a 6-month free access for the papers without open access: 

Celebrating World Wood Day on 21 March

World Wood Day http://www.worldwoodday.org/about.php was first introduced in 2010 beginning in-person in 2013 in Dar Eslam, Tanzania. The in-person meetings were stopped after Austria in 2019 because of Covid. These meetings have been virtual each year since and are planned to begin again in-person in Tokyo, Japan in 2025.

The theme of 2023 was Wood in Cultural Heritage. Listen to the opening speech of the 2023 celebrations by Howard Rosen http://www.worldwoodday.org/2023/news/252, Chairman of the International Wood Culture Society (IWCS), and Coordinator of IUFRO Research Group 5.15.00 Forest products culture:

One of the events to mark the day was the 2023 Online World Wood Day Symposium and The Fifth IUFRO Forest Products Culture Colloquium on 21 and 22 March 2023:

Linking Forests, Energy and Livelihoods Can Help to Faster Achieve SDGs

More integrated approaches between forests, energy and livelihoods can accelerate progress towards the Sustainable Development Goals, according to a joint Issue Brief  published on 4 April 2023 by the UN Forum on Forests Secretariat (UNFFS), the Food and Agriculture Organization of the United Nations (FAO), the International Union of Forest Research Organizations (IUFRO) and the United Nations Development Programme (UNDP).

Forests, Energy and Livelihoods was prepared with the aim to inform discussions at a hybrid global event at UNHQ in New York, convened on 4 April by the Bureau of the 18th session of the UNFF and ahead of the UN General Assembly Summit on Sustainable Development Goals in September.
About the event:  https://www.un.org/esa/forests/events/unff18-bureau-event-forests-energy-livelihoods/index.html

"Particularly given the current global economic situation, the prospect of a global recession and increased energy and commodity prices, it is vital to recognize the role of forests and sustainable management of forests in achieving sustainable development," the four organizations say in the brief.
News story:  https://www.fao.org/forestry/news/100606/en/

"Forests provide solutions for addressing many developmental challenges. More than 1.6 billion people worldwide strongly depend on forests for food, medicine, fuel and for their livelihoods."

It is estimated that about half of the wood extracted from forests is burnt as fuel for energy uses, with the highest share of around 90 percent in Africa. Wood fuels are traditionally used for cooking and heating by more than 2 billion people worldwide.

Nelson Grima, IUFRO, is one of the lead authors of the Issue Brief and was an invited speaker at the event. He says, "It is also imperative to invest in the advancement of forest-related research in all its different fields, both at the theoretical and implementation level, considering the needs and knowledge of stakeholder groups."

New Study on International Forest Governance Initiated

Nelson Grima, GFEP Project Manager

In 2010, IUFRO's GFEP https://www.iufro.org/science/gfep/ published a report on the complexities and challenges of international forest governance https://www.iufro.org/science/gfep/gfep-initiative/panel-on-forest-regime/. Since then, these complexities and challenges have increased in multiple ways. New programs and arrangements have emerged at all scales, and the interactions among them, including synergies and trade-offs, are often unclear. At the same time, forest-related global discussions and negotiations continue, impacting the future of not only forests, but also the livelihoods and well-being of people.

In this context, IUFRO has initiated a global scientific follow-up study in the frame of its GFEP Programme. The goal is to produce a comprehensive peer-reviewed scientific assessment report and an associated policy brief on international forest governance by the first half of 2024.

The assessment aims to inform ongoing policy discussions on the 2030 Agenda for Sustainable Development. It will provide input to the future sessions of the United Nations Forum on Forests (UNFF), the United Nations Framework Convention on Climate Change (UNFCCC), the Convention on Biological Diversity (CBD), and the High-Level Political Forum on Sustainable Development (HLPF), as well as other international processes relevant to forest policies and related issues.

This new assessment will examine the main aspects of the current landscape of international forest governance, analyzing and synthesizing scientific information published since the release of the global assessment report of 2010. It will provide an update on governance changes since 2010, including actors and instruments; an overview of the forest-related finance landscape; an identification and analysis of relevant current discourses; and an analysis of the different governance designs for the future, including deficits and alternatives.

The assessment will be led by a core team of eight experts in different fields of forest governance from Africa, Asia-Pacific, Europe, North and South America, supported by a larger number of contributing authors.

Tree-based Diversified Land-use Systems: Augmenting Livelihood Security and Industrial Growth

Report by Swoyambhu Amatya, Coordinator of IUFRO Research Group 1.04.00 Agroforestry, S. K. Chauhan, Deputy Coordinator of RG 1.04.00, and Parvinder Kaushal, former Coordinator of IUFRO Working Party on Plantations Establishment, https://www.iufro.org/science/divisions/division-1/10000/10400/

The conference on tree-based land use systems held on 15-17 February 2023 was kindly hosted by Navsari Agricultural University, Navsari Gujarat, India, and supported by the Indian Ecological Society, Ludhiana Punjab.

The conference focused on the field of forestry and tree-based land use systems including agroforestry to attract scientists from multiple disciplines and a wide range of stakeholders from throughout the country and overseas. Topics ranged from production and raising to plantation, tendering, tending, harvesting, processing and marketing issues of trees, tree products and other products derived from tree-based land use systems.

Presentations included two keynote addresses and 12 lead lectures, including three from USA in online mode. A total of 198 oral and poster presentations were made. Participants came from more than 18 Indian states representing different government and private institutions, NGOs, wood and forest-based industries. There were also two online participants from Japan and two in person participants from Nepal.

The conference had six broad themes namely:

  • Farmers, Foresters, and Fabricators
  • Agroforestry - A Landscape with Trees for Lives and Livelihood
  • Tree Improvement and Ecology
  • Utilization and Value Addition of Forest Genetic Resources
  • Forests, Climate Change and Natural Resource Conservation
  • Silviculture, Forest Management, Economics and Policy

Key points of deliberations also centered on scientific utilization and conservation of forest genetic resources through natural resource management.

Participants identified a need for supply chain/linkages between different stakeholders leading to food, nutrition, environmental and livelihood security. Enhanced productivity to address rising demands from wood-based industries were discussed. Tree improvement programs should focus on the selection of new clones or varieties of fast-growing species. Presentations also covered the utilization of NTFPs and the development of value-added products.

There is a need to address policy issues related to increased ecosystem services through forest conservation and trees outside forest enhancement vis-à-vis supply chain and marketing issues of tree-based land use system production.

Close-to-nature Silviculture: Experiments and Modelling for Forestry Practice

Report by Jens Peter Skovsgaard, Coordinator of IUFRO Division 1 Silviculture, and Don Hodges, Coordinator of IUFRO Division 4 Forest Assessment, Modelling and Management

IUFRO Divisions 1 and 4 joined forces and hosted an IUFRO All-Division 1 & 4 Online Conference entitled "Close-to nature silviculture:  experiments and modelling for forestry practice" on 7 and 8 February 2023, which was attended by 117 participants. Close-to-nature silviculture is considered an alternative approach to traditional or conventional silviculture. It aims to emulate nature and to integrate natural processes into management.

The conference aimed to showcase and discuss the concept, science, and practice of close-to-nature silviculture, focusing on experiments and modelling for forestry practice. Challenges, advances, and limitations in close-to-nature silviculture approaches were presented and actively discussed among presenters and conference participants from Africa, Asia, Europe, and North America.

Efforts are currently underway in many regions of the world to move away from single-species planation management to uneven-aged mixed species stands as such stands are often considered closer to the natural forest type. Some of the challenges to implement close-to-nature silviculture are the lack of data to adequately model the impact of silviculture on growth, stem quality, and tree health in uneven-aged, mixed species stands. Similarly, selecting appropriate sampling methods in uneven-aged stands with variable density structures is a challenge.

Regeneration in close-to-nature silviculture systems and modelling regeneration and early growth were identified as potential topics of interest for an upcoming online conference to be hosted jointly by Divisions 1 and 4.

Managing Mixtures vs. Monocultures: What Do We Know?

Planted forests represent an essential nature-based solution to meet the growing demand for sustainable wood while contributing to climate change mitigation and ecosystem restoration. More diverse planted forests can meet broader societal goals by enhancing resilience and ecosystem services compared to monoculture plantations. However, there is often a gap in the information, experience, and genetic material necessary to implement mixed-species planted forests at scale.

To address this knowledge gap, the UN Food and Agriculture Organization (FAO), the TreeDivNet network, and the International Commission on Poplars and Other Fast-Growing Trees Sustaining People and the Environment (IPC) organized a workshop aimed at reviewing the state of the art in the management of mixed and pure planted forests.

The workshop on 29 and 30 September 2022 contributed to the Cambio https://www.cambio-treediversity.com/ and MixForChange projects https://treedivnet.ugent.be/ProjectMixForChange.html, and was hosted by the IUFRO Task Force Resilient Planted Forests https://www.iufro.org/science/task-forces/resilient-planted-forests/ serving society and bioeconomy. It was titled "Management of mixed and pure planted forests:  Stock-taking of science and practice" and gathered 35 participants from across the globe at FAO headquarters, Rome, Italy and included a panel discussion that brought together country representatives from Argentina, Italy, Madagascar, Uganda, and the United States of America.

According to FAO's Global Forest Resources Assessment https://www.fao.org/3/ca9825en/ca9825en.pdf, the area of planted forests has increased by 72% since 1990, from 170 million hectares to 293 million hectares in 2020. As the role of sustainable wood in meeting environmental and socioeconomic objectives is increasingly being recognized, demand for sustainable wood is likely to expand and be met through planted forests. The urgent need to restore degraded land globally also demands consideration of the role of planted forests.

Globally distributed mixed-species experiments associated to TreeDivNet provide scientific evidence for increased resilience and ecosystem service provision of mixed-species planted forests compared to monospecific ones. Increasing tree species richness is associated with increasing multifunctionality, biodiversity and productivity. Mixtures are also important to spread risks, which is especially relevant as climate change is likely to significantly increase abiotic and biotic threats to planted forests.

The rising demand for renewable materials and for nature-based solutions to address climate change challenges presents both opportunities and risks for forestry investments. More diverse planted forests can offer attractive options for landholders, including smallholders, to invest in forestry. The potential for more mixed planted forests increases with the increasing importance of marketable ecosystem services other than timber production.

However, the wide implementation of diverse planted forests requires easy, practical guidelines to overcome operational complexity. There is a great mismatch between the availability of research results and technologies and their adoption by rural producers, especially on small and medium-sized properties. To enable the expansion of mixed plantations, they need to be perceived as technically sound, economically viable, and socially acceptable.

Participants agreed on a roadmap aimed at launching a joint publication in November 2023 at the International Congress on Planted Forests (ICPF2023 https://www.plantedforests.org/icpf-2023/), to contribute to bridging the gap between science and practice on the topic of mixed species planted forests.

The webinar, which was kindly supported by the Arts et Métiers Institute of Technology and attracted 57 participants from a large number of countries, can we rewatched at:

Three short presentations led by Team-Leader Professor Satoru Tsuchikawa were offered to the participants. The webinar started with Dr. Tsuchikawa providing an effective overview of the research conducted in his research group and how it has evolved from the study of the wood sawing process and saw dynamics to the development of new optical measurement systems for the optimization and quality control of processes involved in the transformation of wood and agricultural products. This set the stage for the two scientific presentations.

The scientific presentations were given by Dr. Te Ma and Dr. Tetsuya Iganaki. They explored and discussed the combination of various measurement techniques and data mining approaches with the goal to understand water transport in wood, identify wood species, analyze wood properties, develop a cheap moisture meter, evaluate crystallinity as a relationship to wood strength. These presentations were followed by a dynamic Q&A session involving all three presenters.

Othmar Griess (1929-2023)

We are sad to inform the IUFRO community about the passing of DI Dr. Othmar Griess, IUFRO DSA recipient and former coordinator of several units of IUFRO Division 4.

Othmar has been highly active during all his professional life and beyond. He has focused his research efforts on innovation in forest management, electronic data processing; and, as Managing Director of the STUGES (Study Society of Austrian Forest Owners, Vienna), he was among the first forest professionals who during the early 1980s used orthophotos in forest management planning. He contributed to the modernization of the inventory technology with new timber yield tables and the appraisal system with new sorting boards and variability charts.

Othmar began his international activities at scientific conferences in 1966. He has an extensive record of long-term and dedicated service to IUFRO in various positions, starting as Leader of IUFRO SG 4.04.00 Forest Management planning and business economy (1983–1995), continuing as Coordinator of WP 4.04.07 Terminology of forest management planning (1996–2010) and since 2010 – Deputy Coordinator of former 4.04.07 that was renamed to 4.04.03 SilvaPlan:  Terminology of forest management planning. His intensive work on explaining and defining technical terms has resulted in the IUFRO World Series Vol. 9-de (1998) and in an online terminology database on forest management.

In 1995 Othmar received the IUFRO Distinguished Service Award for his contribution to the organization of Division 4 research on forest management and planning, managerial economics and forest terminology. (https://www.iufro.org/uploads/media/iufro-distinguished-service-award-winners-2019.pdf) Othmar has promoted the idea of international scientific cooperation with outstanding idealism and success as a passionate worker for the great benefit to IUFRO. We will always remember with gratitude his and his wife Ingeborg's friendly and supportive attitude towards IUFRO.

William (Bill) Manning (1941-2023)

It is with great sadness that we inform you that Prof. William (Bill) J. Manning, Professor emeritus at the University of Massachusetts at Amherst, USA, passed away on 4 March 2023. Bill was a widely known and well-respected scientist who pioneered research on the impacts of air pollution on plants.

Although he was not an IUFRO officeholder, he was a very good friend of IUFRO and actively participated in the activities of the RG 8.04.00 (formerly 7.01.00) on air pollution and climate change impacts on forest ecosystems. For instance, he gave an invited speech on this topic at the IUFRO 125th anniversary in 2017. When he retired, the RG 8.04.00 established 'The Bill Manning Award' for the best poster presentation at its biennial conferences, as a recognition of Bill's mentoring role in forestry and environmental sciences.

For over 30 years Prof. Manning was an Editor-in-Chief of the prestigious Environmental Pollution journal. Scientists specializing in air pollution and climate change impacts on plant ecosystems recognize Bill's enormous contribution to the development of this subject. We mourn Bill's loss not only as a scientist, but particularly as a gentleman colleague of a cheerful demeanor and with an exceptional sense of humor. We offer our sincerest condolences to his wife and family.

Responding to Environmental Issues Through Adaptive Collaborative Management: From Forest Communities to Global Actors

This open access publication co-edited by anthropologist Carol J. Pierce Colfer and forester Ravi Prabhu compiles the writings of a total of 45 authors, most of whom hail from developing countries. It is the second in a series – the other being Adaptive Collaborative Management of Forest Landscapes:  Villagers, Bureaucrats and Civil Society (2022, also open access). The genesis of these books involved a query to those partners who had participated in ACM's early days (2000s). What had they learned about ACM in the two intervening decades?

This second book, which focuses on three islands in Indonesia (Sumatra, Sulawesi and Java) and five countries in sub-Saharan Africa (Cameroon, Kenya, Malawi, Uganda and Zimbabwe), includes three revisits to former ACM research sites from the early 2000s to assess what has endured and what has fallen away; new methods that build on the ACM approach; a thought experiment on how to scale up more effectively; and some ideas on how to support and encourage a 'culture of care', in our efforts to address environmental issues and those of the human beings who inhabit forested areas particularly.

Towards a Global Sentinel Plants Research Strategy to Prevent New Introductions of Non-native Pests and Pathogens in Forests. The Experience of HOMED

Many IUFRO Officeholders contributed to this paper published by RIO, the Research, Ideas and Outcomes Journal:  https://riojournal.com/article/96744/
The ever-growing volume of intercontinental trade of living plants is considered responsible for the increasing introduction of seriously damaging non-native forest insects and fungal pathogens in all parts of the world. The use of sentinel woody plants in experimental plantings, Botanical Gardens and Arboreta has been experimentally validated as a tool for identifying possible unknown future threats prior to their introduction into new countries.

Approaches to Forecasting Damage by Invasive Forest Insects and Pathogens:  A Cross-Assessment

Several IUFRO Officeholders are among the authors of this paper published on 1 March 2023 in BioScience, Volume 73, Pages 85–111, https://doi.org/10.1093/biosci/biac108
Nonnative insects and pathogens pose major threats to forest ecosystems worldwide, greatly diminishing the ecosystem services trees provide. The authors evaluate how and under what conditions the assumptions of each approach are best met and propose methods for integrating multiple approaches to improve our forecasting ability and prevent losses from invasive pests.
