Guariguata, M.R.Nasi, RobertKanninen, M.[Forest degradation: it is not a matter of new definitions]Forest degradation: it is not a matter of new definitions

Mangrove forests occur along ocean coastlines throughout the tropics, and support numerous ecosystem services, including fisheries production and nutrient cycling. However, the areal extent of mangrove forests has declined by 30–50% over the past half century as a result of coastal development, a...

Many studies have suggested various kinds of forest policies, management planning and practices to help forests adapt to climate change. These recommendations are often generic, based mostly on case studies from temperate countries and rarely from Africa. We argue that policy and management recom...


Kalame, F.B.Nkem, J.Idinoba, M.Kanninen, M.[Matching national forest policies and management practices for climate change adaptation in Burkina Faso and Ghana]Matching national forest policies and management practices for climate change adaptation in Burkina Faso and Ghana

In Costa Rica, most reforestation trials with native species were established in the tropical humid region. In the dry tropics, research on the performance of native species in forest plantations is incipient and trials comparing pure and mixed designs are limited. This paper presents the results...

During the last two decades, the Costa Rican government has promoted the establishment of Tectona grandis plantations for sawn timber. However, there is a lack of knowledge on optimum spacing and on thinning regimes, in contrast to high expectations of final mean diameter at breast height (DBH) b...


Kanninen, M.Pérez Cordero, L.D.Montero, M.Viquez, E.[Intensity and timing of the first thinning of Tectona grandis plantations in Costa Rica: results of a thinning trial]Intensity and timing of the first thinning of Tectona grandis plantations in Costa Rica: results of a thinning trial

The area of forest plantations in the tropics worldwide is increasing as a response to the expansion of degraded lands. Rural farmers of many regions of the dry and humid areas are responding to government and other incentives, dedicating portions of their land to native and exotic tree plantatio...


Piotto, D.Montagnini, F.Kanninen, M.Ugalde, L.Viquez, E.[Forest plantations in Costa Rica and Nicaragua: performance of species and preferences of farmers]Forest plantations in Costa Rica and Nicaragua: performance of species and preferences of farmers

The Costa Rican government has promoted the establishment of high yielding plantations, expecting to produce high quality timber. Nowdays the management of some species have been uncertain, since wood quality and yield are becoming lower than expected. Heartwood content is a determinant character...


Pérez, D.Kanninen, M.Matamoros, F.Fonseca, W.Chaves, E.[Heartwood, sapwood and bark content of Bombacopsis quinata in Costa Rica]Heartwood, sapwood and bark content of Bombacopsis quinata in Costa Rica

This study determines whether the establishment of tropical protected areas (PAs) has led to a reduction in deforestation within their boundaries or whether deforestation has been displaced to adjacent unprotected areas: a process termed neighbourhood leakage. We processed and analysed 98 corres...


Gaveau, D.L.A.Epting, J.Lyne, O.Linkie, M.Kumara, I.Kanninen, M.Leader-Williams, N.[Evaluating whether protected areas reduce tropical deforestation in Sumatra]Evaluating whether protected areas reduce tropical deforestation in Sumatra

Payments for reduced carbon emissions from deforestation (RED) are now attracting attention as a way to halt tropical deforestation. Northern Sumatra comprises an area of 65 000 km2 that is both the site of Indonesia’s first planned RED initiative, and the stronghold of 92% of remaining Sumatran ...
