Latest in forest science to be showcased in Brazil
IUFRO Spotlight issues up to September 2019 will primarily focus on the XXV IUFRO World Congress that will take place on 29 September – 5 October 2019 in Curitiba, Brazil.
Individual Congress sessions will be highlighted in order to draw attention to the broader Congress themes, the wide variety of topics that will be addressed at the Congress and their importance on a regional and global scale.
For the first Spotlight in this series we have invited Dr. Jerry Vanclay, Chair of the IUFRO World Congress Scientific Committee, to offer a sneak peak of the attractive and comprehensive technical program and talk about his personal expectations of the Congress.
The interconnection of forests and people goes beyond forest management and forest products. This was dramatically illustrated during 2015 floods in Malawi when people climbed trees and were thereby saved from floods that killed over a hundred people in Traditional Authority Mlolo of the Nsanje District.

“The portfolio of goods and services from forests is now very different to that two decades ago; yet there is a disconnect between the institutional framework and these new forms of forest use, leading to efficiency, equity and legitimacy deficits,” said Dr. John Innes, Dean of the Faculty of Forestry at the University of British Columbia, Canada.
The changes – from forest planting and forest harvesting and operations, to forest use and forest products – occur at different levels. Today, forests produce a complex array of products from forest ecosystem services to timber and bio-products.
Market values are increasingly being attached to forest ecosystem services and this is changing the value systems associated with forestry. Read more…
IUFRO 125th Anniversary Congress Spotlight #52 – Building on tradition to plan for the future of forests
“We’re trying to avoid throwing the baby out with the bathwater,” said Dr. Jens Peter Skovsgaard of the Swedish University of Agricultural Sciences in Alnarp, Sweden.
He was speaking about forestry operations and research and how change can be evolutionary rather than revolutionary. Dr. Skovsgaard is coordinator of a session entitled: Forestry “Classic” for the Future, at the IUFRO 125th Anniversary Congress in Freiburg, Germany in September. Read more…
IUFRO Regional Congress for Asia and Oceania 2016
24 – 27 October 2016, Beijing, China
Forests for Sustainable Development: The Role of Research
The Beijing Declaration
Keynote speaker at the IUFRO Regional Congress for Asia and Oceania –
Forests for Sustainable Development: The Role of Research
Professor Zhang, the IUFRO Regional Congress for Asia and Oceania 2016 is jointly organized by IUFRO and the Chinese Academy of Forestry. This is the first Congress of its kind to be held in the region of Asia and Oceania and will offer an extraordinary opportunity for enhancing forest science cooperation. You are one of the leading scientists in silviculture and forest management in China and have a long experience in the establishment of planted forests on the one hand, and sustainable forest management on the other hand. The Congress will particularly focus on these two areas with its themes “Planted forests for fostering a greener economy”, and “Sustainable forest management for enhanced provision of ecosystem services”.

Consumers and Industry: Keen on Green
Looking toward the future is enough to make you, ahem, “turn green” with envy.
It’s all about a greener future.
That future and, more specifically, how it relates to the world’s forests will be one of many subjects discussed at the XXIV IUFRO World Congress in Salt Lake City, Utah, this fall.
A session there, entitled Forests and Forest Products for a Greener Future will look at how business and marketing will contribute to that goal.
Organized by Eric Hansen of Oregon State University, Tom Hammett of Virginia Tech and Birger Solberg of the Norwegian University of Life Sciences, it will cover a wide range of business and marketing theory topics that address how products and markets (timber and non-timber) can be expected to contribute to the greening effect.
Forests play a major role in achieving Millennium Development Goal 1 to eradicate extreme poverty and hunger and in striving for food security. Globally, millions of people depend on forests for their food security and nutrition, directly through the consumption or sale of foods produced in forests, indirectly through forest-related employment and income, forest ecosystem services, and forest biodiversity.
Current approaches to increasing food security tend to concentrate on agricultural solutions, ranging from intensification of agricultural production outside of forests to promoting agroforestry systems. Policy recommendations to establish a framework for promoting food security from forests, however, have so far been rather general and no framework addresses the relationship between forests and food security directly.
The “International Conference on Forests for Food Security and Nutrition”, held at FAO Headquarters in Rome in May 2013, inter alia conveyed the key message that forests, trees and agroforestry systems demand greater attention in strategies for food security and nutrition and in the fight against hunger. It also called for improved data collection at national and international levels.
A changing forest sector: Globalization triggers bio-economy and the search for new business opportunities
Scientists, practitioners and decision-makers from around the world meet in Vancouver, Canada from 27 to 30 August 2013 to discuss the implications of globalization on forests and their management.
(Vancouver/Vienna, 27 August 2013) Globalization is changing forests and the forest sector. Increases in international trade and investments have altered the global business environment for forestry. The growing world population moving towards nine billion by 2050, economic growth, rising resources demand and increasing environmental concerns are other drivers fostering transformation in forestry and the management of forests. New players enter the global market, and the bio-economy –– the production of ‘green’ products from renewable resources –– is gaining weight. From 27 to 30 August 2013, more than 100 representatives from research, industry and government will discuss how global trends influence forest resources, and how new opportunities for forest entrepreneurs and a more resource efficient society can be harnessed. The Conference has been organized by the University of British Columbia (UBC), Faculty of Forestry, on behalf of the Task Force “Resources for the Future” of the International Union of Forest Research Organizations (IUFRO).

The primary objective of the first paper was to determine if Caesalpinia velutina and Giricidia sepium fuelwood plantations in Nicaragua could be economically viable for smallholders. It was concluded that fuelwood plantation yields according to product-specific requirements were essential for the economic viability analysis. In the context of this study and contrarily to public perception, farm-based Caesalpinia velutina and Giricidia sepium fuelwood plantations could be economically viable over longer rotations.
The second paper addressed the role of Sewage Treatment Plants (STPs). The sewage treatment process generates a solid waste named sewage sludge, a material rich in organic matter and nutrients. According to this study sewage sludge showed a great potential in the production of forest seedlings. It recommends the use of composite substrates with sewage sludge, because it minimizes the need for acquisition of commercial substrates, decreasing production costs by increasing productivity and disposing this waste in a more sustainable way.
The aim of the third paper was to contribute to the understanding of the growth dynamics of native species of Araucaria taking into account its complex structure and by the analysis of growth and competition, to subsidize the forest management and its conservation. The endeavour of trees to compete for light can be used to determine the best management and production options.
The fourth paper studied the growth dynamics of different species in an Araucaria forest remnant stand. It concluded that there is evidence that in the past the stand of Araucaria Angustifolia should have been thinned more intensively. Competition indexes are useful and can be used to recover information in unmanaged stands to optimize resources, and they can also be used as a reference to manage other stands in similar conditions.
The aim of the fifth paper was to determine the percentage of samples that best reflects the actual diameter distribution in a 1,000 ha of primary Amazon forest in Sinop, Mato Grosso State, Brazil. When considering the whole area, 5% sample intensity has proven to be sufficient to estimate the horizontal structure of trees above 30 cm of DBH. Considering the diversity of the Amazon rainforest, it is still not possible to extrapolate this anlysis of the diameter distribution. Further replication studies are required to establish sample intensities and methods for different forest structures.
