On 14 June, the Third IUFRO Latin American Congress (IUFROLAT 2013), one of the largest forest research events in Latin America, came to a close.
Results of a stable state policy in support of forests: the case of Chile
Friday, 14 June 2013At the beginning of his speech Hans Grosse Werner congratulated the congress organizers on this splendid event and underlined that this congress will certainly have increased the visibility of IUFRO in Latin America.
The focus of the presentation was on the development of forest cover and forest legislation and institutions in Chile with particular emphasis on forest plantations, production and exports, progress made and pending tasks for the future.
Grosse gave an overview of Chilean forest history from prehistoric times to colonialism and the dramatic loss of forest cover mainly due to mining activities in the 19th century, and important steps in implementing regulative legislation in the 20th century.
“Thanks to the policies and laws that were introduced between 1912 and 2011, about 30% of the native forest could be recovered and 2.6 million ha of plantation forests could be added so that the overall forest cover in Chile eventually amounts to 16 million ha today”, said Grosse.
These legislative instruments relate mainly to the introduction of inventories, reforestation programmes, management plans, conservation areas and the development of forest curricula. However, the establishment of institutions to implement and control these regulations and ensure sustainability lagged somewhat behind. The Chilean forest institute INFOR and the national forest corporation CONAF were only founded in 1961 and 1973, respectively. A Ministry for the Environment was set up in 2010.
Yet, despite the progress made, there are still challenges to be overcome. One of these, says Grosse in conclusion, is the strengthening of the small and medium-sized forest-related enterprises. There are incentive programmes in place, but more needs to be done.
This keynote address was the final one in a series of high-level keynote speeches presented in the course of the 3rd IUFRO Latin American Congress.

The session addressed the very important issue of the trade-offs between biomass harvest, carbon storage and biodiversity. Biomass harvest is negatively correlated with biomass storage and, in most cases, with biodiversity.
A key finding of the first presentation, which dealt with a permanent plot experiment in the Amazon, is that logging intensity affects biomass recovery rate and period. The study determined that increased logging intensity is ensued by increased recovery rate, but increases the recovery period.
Another presentation highlighted the effects of logging after 30 years on tree diameter, timber species and floristic diversity. Floristic diversity had recovered to the original state. Conversely, diameter distribution was less heterogeneous and tree species composition had shifted to pioneer and other light demanding species.
The role of individual big trees was also highlighted in a presentation. The study conducted in Pará, Amazon, found that selective logging caused a net biomass storage decrease. Moreover, selective logging creates instability in stands, which results in elevated natural mortality of individual big trees, even 8 years subsequent to logging.
Another presentation emphasised the role of disturbance regimes, showing data that El Nino decreased standing biomass more than logging; where mature stands suffered more damage than newly logged stands. Emphasis was placed on the importance of rotation cycles, as the risk of devastating disturbance regimes increased with increasing rotation periods.

In this session the speakers gave examples of specific education systems and related in Latin America, Europe and the USA.
One major expectation of forest education is a shift in the focus of the general research field from “forestry” to “forests” including the transformation of the future graduates’ image. There is also evidence that linear career progressions have decreased and thus, roles and skills of forest students are required to adapt to changes.
One of the major future challenges for developing student skills is that education needs to be outcome driven; in many systems however it is still content driven. The employability and thus, the adaptation of education systems to the demands of future employers have gained far more importance.
Moreover the need for teachers to cultivate curiosity, passion and creativity in their students has been identified. General demands put forward for consideration in the process of transforming forest studies include the approach of convergent thinking and a shift away from linear thinking.
The gender and minority involvement in forest and natural management studies also requires more research. Furthermore, the accreditation of study programs and thus the comparability of degrees have been addressed by the speakers. Complex issues that involve changing demographics, structure of universities, social trends, and state budgets are among the challenges which many education institutions face.
In conclusion, the main change of education that is required is that foresters are expected to have greater competencies in many different subject areas including the fields of natural resources and landscape management.

Peter Holmgren, Director-General of the Center for International Forestry Research, presented his Keynote Address, “Forestry in a landscape approach – developing evidence-based policies”, during the final day of sessions of IUFROLAT III.
Holmgren, presented a series of questions, framing a way forward to position forestry alongside that of other land users to address multi-sector problems in a landscape approach.
In his first question, “what are the policies we need?” he defined what shapes many of the forest policies, not only in Latin America, also on a global scale. These included poverty reduction, nutrition and food security, climate change adaptation and mitigation, preservation of biological diversity, and achieving green growth and equity. He outlined how forestry is related to 9 out of 12 sustainable development goals, and we need to think about where forestry can play a role in policies being politically relevant and providing positive contributions.
He transitioned by asking, “how does forestry contribute?” and presented his thoughts on how forestry is portrayed on increasingly large level. Forestry has become an environmental issue and forestry related questions are often blurred with perceptions of forests on a whole. Topics such as REDD, illegal logging, etc have brought attention to forests, yet fundamentally, they are not forestry issues. Holmgren proclaimed, “We need to take forestry out of the forest”. He explained how the adoption of a broader definition of the role of forestry, and how it applies to address key issues across a landscape, could be employed.
Expanding on this thought, Holmgren asked the question, “how is a landscape approach different?” In answer, he identified a sustainable landscape framework that focuses on objectives such as; ensuring livelihood provision, sustaining ecosystem services, securing food and non-food products, mitigating pollution and achieving resource efficiency. To do so, we need to see landscapes as a large part of sustainable development, identify multiple objectives and acknowledge that there are beneficial synergies as well as trade-offs. We need to build our work to ensure that local stakeholders are in charge and help strengthen the role of sectors to support them building a holistic landscape.
In order to provide this support, we must incorporate evidence-based approach in our science and policy interface. He answered his final question, “what is different about an evidence-based approach?”, by introducing new models that identified the importance of satisfying demand by stakeholders for information with relevant, credible forest science research.
Holmgren closed with some take home messages:
- It is time to take forestry out of the forest,
- We need a landscape approach to deal with sustainable development challenges; and
- Our plans for the future must be evidence-based.
Bosques, Biodiversidad y Servicios Ecosistémicos / Forests, Biodiversity and Ecosystem Services

The session offered insight into functional ecology, with emphasis on climatic conditions along elevation gradients showing that biodiversity decreases with increasing altitude. It also dealt with the provision of ecosystem services in relation with biodiversity. Biodiversity is essential for pest damage resistance, for example. Source dilution, chemical signals and activity of natural enemies are identified as being essential for ensuring low pest damage. With increased source dilution, pests are less likely to establish themselves in a diverse setting. With increased chemical signals associated with diverse flora, pests are less likely to find their favourite source. And with a high number of natural enemies, whose presence is correlated with high biodiversity, pests are less likely to cause damage. Hence, diversification on a stand/landscape level is needed to ensure the provision of forest ecosystem services.
Plant conservation in Southeast Asia was another topic. In Malaysia, for example, efforts to preserve plants have become a prevalent goal for scientists. Diversity is vast, and since 40 – 50 % of the preserved species are endemic, 24% of which are either endangered (EN) or critically endangered (CR), conservation is a central goal. While the pleas of scientists are being heard in some cases, legal frameworks are needed to protect these species.
A presentation on the carbon sequestration potential for complex mosaic forest landscapes in western Mexico aimed at addressing shifting cultivation, framed in the carbon emission discourse. With shifting cultivation, carbon is released to the atmosphere, adding to GHG concentrations. However, the study showed that on a landscape level, there are no net carbon dioxide emissions, as the carbon sequestration rate of forest re-growth compensates for the carbon emission from shifting cultivation.
The presentation entitled “Native forest cover increase: drivers and implications on ecosystem services”, focused on why some areas in the Piracicaba river basin were allowed to reforest. Satellite imagery helped determine deforestation and reforestation from 1990 – 2010. Having preselected variables, the results demonstrate that natural reforestation occurs when slopes exceed 30%, when water proximity is less than 100 m, when annual rainfall exceeds 1400 mm, when elevation is lower than 400 m below sea level or more than 800 m above sea level, and when vicinity to towns is more than 7 km.
The final paper focused on Chakras, forestry systems that are employed by indigenous peoples in the Amazon. Plant composition in Chakras is heterogeneous; they provide multiple sources of food, are biodiverse and function as stores of carbon. The presented study demonstrated that in Chakras, fauna is more diverse, carbon storage is higher in both biomass and necromass than in comparable Cocoa plantations.

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.

In this session the audience was presented with a mixed bag of papers: 3 papers focussing on TFK, and other three on contributions to local economies. Emphasis was placed on the fact that there is a lot of traditional knowledge out there, which is rapidly getting lost because of various factors. Among the suggestions of what can be done to preserve traditional forest knowledge, the example of Korea was presented which established together with other countries of East Asia the Asian Center for Traditional Forest Knowledge as an institutional approach for the preservation of TFK. This was also recommended as an idea to implement in Latin America.
However, TFK should not only be kept as a historical asset but also be combined with innovation – as a logical consequence – whilst considering and adapting to changes in economy and society.The importance of markets for traditional products was mentioned to be crucial for the preservation of TFK. In this context, innovative aspects and development must be originated by the people concerned and traditional organisations be strengthened in a horizontal way.
With regard to contributions of forests to local economies, initiatives in the domain of medicinal plants, the importance of equal benefit sharing (EBS) and smallholder land-use were highlighted, as well as the optimal use of the whole set of services that forests can offer.
