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.

What REDD+ looks like on the ground: evidence from the Amazon and beyond
Moderator: Niels Elers Koch, IUFRO President

Agricultural expansion has been identified as a key driver of deforestation in developing countries. The IPCC estimated that carbon dioxide emissions, as a consequence of deforestation, amounted to 20% of all anthropogenically induced carbon dioxide emissions in the 1990s. Reducing Emissions from Deforestation and Forest Degradation in developing countries (REDD+), has been proclaimed an environmental policy instrument that could potentially provide mitigative benefits for net carbon emissions and biodiversity degradation.
In the session entitled “What REDD+ looks like on the ground: evidence from the Amazon and beyond”, leading scientists addressed the relationship between biodiversity, carbon, forests and people, as well as experiences with the operationalization of REDD+ in Latin America.
The Global Forest Expert Panel (GFEP), which is coordinated by IUFRO, presented a global assessment report on REDD+, which consolidates the research of more than 50 leading scientists. The report constitutes a comprehensive analysis of the synergies and trade-offs between biodiversity, forest management and REDD+.
The assessment report proposes that biodiversity is paramount, as a prerequisite for providing ecosystem services. In the face of disturbance regimes such as climate change, ecosystem resilience, a product of biodiversity, ensures ecosystem service provision.
Moreover, a successful REDD+ implementation, that achieves mitigative net carbon emissions and ensures biodiversity provision, requires, in conjuncture with the implementation, the pursuit of social objectives by securing tenure rights and local engagement. Only when tenure and property rights are clearly defined can a REDD+ implementation be effective.
The session also included presentations on a global comparative study entitled “What REDD+ looks like on the ground: Carried out by CIFOR”. The study, which is t largest project ever undertaken by CIFOR, aims to provide scientific insights on how to ensure that REDD+ measures meet the three “E’s”; Effectiveness, Efficiency, Equity. As the first phase of the study has been completed, the findings of four cases were presented during the session. For more detailed information please visit the CIFOR webpage.

Understanding Relationships between Biodiversity, Carbon, Forests and People: The Key to Achieving REDD+ Objectives
Forests harbour a major proportion of the world’s terrestrial biodiversity and provide a wide range of vitally important ecosystem services – including carbon sequestration and storage. Deforestation and forest degradation continue to erode biodiversity and the capacity of forest ecosystems to help mitigate climate change and provide the goods and services that sustain livelihoods and human well-being locally, and globally. Reducing greenhouse gas emissions from deforestation and forest degradation, and enhancing forest carbon stocks in developing countries (REDD+) is a proposed mechanism which has the potential to realise its primary objective – climate change mitigation – with variable impacts, positive and negative, on biodiversity, forests and people. REDD+ is complex, its proposed activities and implementation mechanisms not yet clearly defined, and therefore surrounded by uncertainty. Because of its high relevance to climate change mitigation, the conservation and sustainable use of forests and their biological diversity, the Expert Panel on Biodiversity, Forest Management and REDD+ was established by the Collaborative Partnership on Forests in December 2011 to carry out this assessment.
The Expert Panel included 24 scientists and other experts from a variety of biophysical and social science disciplines relevant to the topics covered in this assessment report. An additional 18 contributing authors added their expertise to the assessment. Each chapter was prepared by a team of Lead Authors and Contributing Authors led by one or more Coordinating Lead Authors. A full draft of the report and its individual chapters was peer-reviewed prior to its completion. The results of this voluntary collaboration between January and October 2012 are presented in the six inter-related chapters comprising this book.
This assessment report evaluates the implications of forest and land management interventions envisaged under REDD+ in a multidimensional and integrated fashion. It summarises the most current scientific literature that sheds light on the relationships between forest biodiversity and carbon (and other ecosystem services), how these complex relationships may be affected by management activities implemented to achieve REDD+ objectives, the potential synergies and tradeoffs between and among environmental and socio-economic objectives, and their relationship to governance issues. Based on the main findings of the assessment (summarised in Chapter 6), a policy brief entitled ‘REDD+, Biodiversity and People: Opportunities and Risks’ has been prepared especially for policy- and decision-makers.
The full report is formally presented at Forest Day 6 on 2 December during the United Nations Framework Convention on Climate Change (UNFCCC) meeting in Doha, Qatar (26 November-7 December, 2012).
The report, the policy brief and a press release – New Study Suggests Global Pacts Like REDD Ignore Primary Causes of Destruction of Forests – are available for download.

“Forest and Trees: Serving the People of Africa and the World” was a fitting theme for the 1st IUFRO-FORNESSA Regional Congress & ITTO/AFF Forest Policy Day held at the World Agroforestry Centre in Nairobi, Kenya June 25-29. The closing ceremony held late Friday afternoon after the last of the Scientific Sessions adjourned, brought reflections of the week and outlined the importance it had for the region and its people.
Adopted from the discussions and the sessions held throughout the week, The Nairobi Resolution was read allowed to the 350+ scientists, policymakers, and forest stakeholders in attendance at the Congress. The resolution which comes a week after the Rio+20 Sustainable Dialogue on forests reinforces the commitment of African countries to “promote science, technology, innovation and traditional knowledge in order to face forests main challenge: how to turn them productive without destroying them”.
The participants of the Congress voiced 7 commitments for the future:
- Adopt people-centred approaches for forest research and education focusing on environmental, social and economic pillars;
- Further expand the scope of forest research, training and education to address issues relevant to global sustainability including land use, livelihoods and environment issues;
- Increase information sharing and knowledge management through fostering regional cooperation and networking in African forest research and providing opportunities for scientists to contribute to global issues;
- Combine traditional knowledge with formal scientific research results to design forest and tree management systems to meet local and broader societal needs at varying spatial scales;
- Develop reward systems for successful uptake and adoption of research outputs and build impact analysis in the research project design;
- Invest in science-society communication, including the training on effective communication of research findings, to improve the impact of research for all beneficiaries and improve the link between research, policy and practice; and
- Provide effective platforms for engagement of scientists, policy makers and stakeholders through national, sub-regional and regional mechanisms.
In a region that faces many obstacles using forest and trees to meet local livelihood needs while ensuring a biodiverse and environmentally sustainable landscape the resolution outlines an optimistic future for Africa – it’s forests, it’s trees and it’s people.

Forests are the major source of our ecosystem services that the society avails for its sustenance and healthy growth. Forestry thus has continued to have a very complex and large social dimension with a number of interfaces between forest and society. These interfaces range from exploitation to protection & conservation. They form the key to an interdisciplinary approach between forestry sciences and social sciences, and create the potential for a mutual collaboration between the two. Read more…
