“…Hence, cocoa farms with naturally regenerated timber trees can be given in concession to timber companies for extraction. This puts pressure on cocoa farms (Hansen and Treue 2008) to supply valuable timber to the wood processing sector (Owubah et al 2001). In spite of the fact that forestry policies require cocoa farmers to be compensated for damage incurred from harvesting of timber by logging companies, there is no official mechanism for determining compensation (Asare 2006b).…”

Cocoa (Theobroma cacao L.) growing systems in Ghana and West Africa consist of diverse tree species and densities. This study was conducted to determine factors that influence tree species configurations and how tree characteristics affect canopy cover in cocoa farms. Eighty-six farmers and corresponding farms were selected in a systematic approach in four districts across two agro-ecological zones in Ghana. Results show that men tend to have larger farm sizes, higher tree density and diversity than women. Tree density and canopy cover of shade trees were low on large farms, but diversity increased with increasing farm sizes. Even though there was a significant correlation between diameter at breast height and crown area for all species investigated, tree species differed considerably in their crown area and thus the amount of ground cover provided. Current recommendations for shade are usually expressed in number of trees per ha, and our results suggest that these should be refined to reflect the effects of species, the size of their diameter at breast height and the crown area.

“…ITTO's member countries produced 173.6 million m 3 of roundwood in 2011, or about an estimate of 204 million m 3 from all tropical forests. Given the fact that up to 87% of logging in the tropics is illegal (Hansen and Treue, 2008;Lawson and MacFaul, 2010;Lawson, 2014) and was usually unreported (Colfer and Resosudarmo, 2002;Asner et al, 2005), and by assuming an average illegal logging rate of 60% (Lawson and MacFaul, 2010), a conservative estimate of roundwood production using the figure reported by ITTO would be 510 million m 3 [= 204/(1−0.6)]. Our model suggests that sawnwood production under RIL is 124.7 m 3 (207.8 m 3 of roundwood) or 77.0% higher than that under the CVL if premature re-entry logging is prevented ( Table 3).…”

HIGHLIGHTS• About 500 million hectares of tropical forests have been degraded due primarily to overexploitation • Preventing premature re-entry into harvested areas can retain up to 34% of carbon stocks in the forests • Adoption of reduced-impact logging and wood processing technologies (RIL+) along with financial incentives can reduce forest fires, forest degradation, maintain timber production, and retain carbon stocks • About US$1.8 Mg CO −1 2 or US$2 billion year −1 is needed for the adoption of RIL+ for the whole tropical production forests.The REDD+ scheme of the United Nations Framework Convention on Climate Change has provided opportunities to manage tropical forests for timber production and carbon emission reductions. To determine the appropriate logging techniques, we analyzed potential timber production and carbon emission reductions under two logging techniques over a 40-year period of selective logging. We found that use of reduced-impact logging (RIL) techniques alone in tropical production forests (PdF) could reduce carbon emissions equivalent to 29-50% of net emissions from tropical deforestation and land use change, while also supplying 45% of global round-wood demand. Adopting RIL plus other improvements (RIL+) in forest management (adopting forest certification and DNA timber tracking to prevent illegal logging) and wood conversion practices (adopting technology to increase recovery of sawn wood), would result in increasing long-term carbon storage in sawn-wood and reduce logging-induced fire-prone wood wastes by 14-184%. For this to happen, about US$2 billion or $1.86 per Mg CO 2 in financial Sasaki et al. Sustainable Management of Tropical Forests incentives are needed annually for parties to adopt RIL+ and to prevent premature re-entry logging. Our findings suggest that future climate policies should explicitly include RIL+ to satisfy the "sustainable management of forests" proviso in the REDD+ scheme, and also count carbon in wood products as eligible credits for trading.

“…Misalnya, suatu sistem yang rumit mengenai hak-hak atas lahan dan kayu yang diselewengkan di Ghana menciptakan insentif bagi para petani untuk menebang pepohonan bernilai ekonomi tinggi di tanah pertanian mereka untuk menghindari perusahaan-perusahaan pembalakan agar tidak menginvasi lahan mereka, menebang pepohonannya, dan menyebabkan kerusakan pada tanaman coklat atau tanaman komoditas lainnya (Hansen dan Treue 2008). Oleh karenanya, kebijakan-kebijakan REDD+ harus memperbaiki sistemsistem hak kepemilikan yang merintangi tanggung jawab yang jelas terhadap tanah dan sumber daya alam.…”
