SUSTAINABLE DEVELOPMENTThe integration of three spheres of resource use* (A) Traditional conservation (B) Environmental economics (C) Traditional development (D) Public forestry (E) Sustainable development (F) Marxist economics (G) Traditional welfare aid Economic Environmental Goals - genetic diversity - environmental resilience - biological productivity (A) Goals - increase satisfaction of basic needs - maximum financial returns (C) (B) S.D. (E) (F) (D) Social Goals - cultural diversity(G) - social justice participation - international stability - enhance equity Modified from Hall, J.E. (1992) Doctoral thesis, Oxford Forestry Institute. *Adapted from Barbier (1987)
Sustainable forest management Sustainable management means the stewardship and use of forest land in a way, and at a rate, that maintains their biodiversity, productivity, regeneration capacity, vitality and their potential to fulfil now, and in the future, relevant ecological, economic and social functions at local, national, and global levels; and that does not cause damage to other ecosystems. Inter-Ministerial Conference on European Forests, Helsinki, 1993

Global forest areas • Global land area 13 billion ha • Global forest area 3952 million ha • Africa, Asia, S & Central America 52% • Europe, N. America, Oceania 48% • Primary forest 36% • Modified natural & semi-natural 60% • Plantations 4% source: Forest Resources Assessment, 2005
Forests are managed for a multitude of uses and values Forest Resources Assessment 2005
Environmental challenges • Natural environment – climate, diseases • Man-made environment – pollution • Managerial environment – additives, technologies • Technological environment - processing and uses (environmentally friendly; diversity; small sizes; new products; market preferences) • Socio-cultural-political environment
Forestry issues in the third millennium • Biodiversity conservation; indigenous species • Environmental quality and changes • Carbon sequestration/trading • Renewable energy • Deforestation - desertification and flooding • Commoditization, trade, incentives, corruption, conflict • Food security, poverty alleviation and human health • Policy reform, professional status and public/political support; internationalization of forests
Research problems in developing countries • Researchers often work in isolation (geographically & socially) or in small groups. • Lack of access to resources - skills - manpower - research facilities - finance - current information - opportunities for international collaboration - channels through which to disseminate results • Lack of recognition between policy makers and scientists
Examples of types of collaboration International political, economic and technical organizations, e.g. NAFTA, EEC,WTA,FAO, UNFF Trade federations , e.g. TTF Joint forest management, e.g. India Co-operative research centres, e.g. ENSIS International research centres, e.g. CIFOR Research networks, e.g. APAFRI, IUFRO Forest education
Sources of forestry information • Primary data • Research Journals • Books • Working papers, reports, etc. • Bibliographic databases • Subject gateways, portals – Intute, GFIS • Institutions, societies - IUFRO

Brief history of Forestry Bureau • Established in 1938 – part of Imperial Agricultural Bureaux (1927) • Took over work of Documentation Section of Imperial Forestry Institute in Oxford (later CFI then OFI) • Professor Schlich (School of Forestry 1905) • Current Monthly Record of forestry literature (1936-39) became Forestry Abstracts (June1939) • Launched with plea that “any shortcomings in it will be leniently regarded…in view of its preparation in circumstances of some difficulty”
Work of Bureau • Literature from Oxford Forestry Institute • Literature received directly by Bureau • Literature abstracted at other libraries (in Oxford or elsewhere in UK) • In 1980/81 the CFI library received • 2376 periodical issues • 1992 ‘bulletins’, • 286 annual reports, • 193 books, 10 maps • 380 periodical titles (12% increase on 1977/78)
What is evidence-based forestry? Professional expertise Best research evidence Stakeholder acceptability (practical values, circumstances)
Evidence based policy • Review existing research • Commission new research • Consult ‘experts’….stakeholders • Consider a wide range of properly costed and appraised options
Evidence based policy quality of information quality of utilization good good poor poor
‘4S’ levels of research evidence Haynes, R.B. Evidence Based Mental Health 2001
convert need for information into an answerable question track down best evidence with which to answer question systematically appraise that evidence for validity (closeness to truth), impact (size of effect) and applicability (usefulness to current purpose) integrate systematic appraisal with professional expertise and with practical values and circumstances defined evaluate effectiveness and efficiency in executing steps 1-4 and improve them (feedback loop) Steps to practise EBF

Cochrane Collaboration • founded in 1993 and named for the British epidemiologist, Archie Cochrane • international non-profit and independent • dedicated to making readily available, worldwide, up-to-date, accurate information about the effects of healthcare • Cochrane Database of Systematic Reviews • promotes the search for evidence in the form of clinical trials and other studies of interventions • Sir Iain Chalmers
Centre for Evidence-Based Conservation • established in the UK in 2003 • support decision making in conservation and environmental management through the production and dissemination of systematic reviews on the effectiveness of management and policy interventions • support from a wide range of organizations in the environmental and academic sectors • undertakes systematic reviews • website acts as the primary gateway to reliable information on effectiveness based on the best available scientific evidence
Systematic reviews • Development of a protocol in collaboration with stakeholders • Development of appropriate searching strategy • Develop and apply critical appraisal tools • internal validity • bias associated with experimental or monitoring designs • Data synthesis • qualitative syntheses • multivariate quantitative approaches • meta-analysis • publication bias
Systematic reviews • Are Japanese Knotweed (Fallopia japonica) Control and Eradication Interventions Effective? • Do Hedgerow Corridors Increase the Population Viability of Woodland Species? • Acupuncture for Parkinson's Disease • Vaccines for measles, mumps and rubella in children
Conclusions • Multiple benefits of forests • Prioritize issues and associated research and policy needs using information better • Need increased collaboration among disciplines and stakeholders • Cooperation between developing and developed countries mutually beneficial • Need targetted financial and political support on the basis of sound evidence
