Not seeing the forest for the trees:The oversight of defaunation in REDD+ and global forest governance

Over the past decade, countries have strived to develop a global governance structure to halt deforestation and forest degradation, by achieving the readiness requirements for Reducing Emissions from Deforestation and forest Degradation (REDD+). Nonetheless, deforestation continues, and seemingly intact forest areas are being degraded. Furthermore, REDD+ may fail to consider the crucial ecosystem functions of forest fauna including seed dispersal and pollination. Throughout the tropics, forest animal populations are depleted by unsustainable hunting to the extent that many forests are increasingly devoid of larger mammals—a condition referred to as empty forests. Large mammals and birds, who often disperse seeds of larger more carbon-rich tree species, are preferentially targeted by hunters and the first to be depleted. Such defaunation has cascading ecosystem effects, changing forest structure and composition with implications for carbon storage capacity. Failure to address defaunation would therefore be a major oversight in REDD+, compromising its long-term viability. We carried out a desktop study reviewing REDD+ documents and national implementation efforts in Colombia, Ecuador, Nigeria, Tanzania, and Indonesia to assess the extent to which they address hunting and acknowledged the ecosystem functions of fauna. We also assessed sub-national REDD+ projects to determine whether they recognized hunting and if and how they incorporated hunting management and wildlife monitoring at the project level. Moreover, we assessed to what extent sub-national REDD+ projects addressed the long-term impacts of the sustainability of hunting on forest ecosystem function including carbon storage. We found that hunting, the risk of defaunation, and its effects have been ignored in the REDD+ policy process at both the international and national levels. At the project level, we found some reference to hunting and the risks posed by the loss of forest fauna, albeit only addressed superficially. Our results underline the fact that forest ecosystems are being reduced to their carbon content and that, despite the rhetoric of biodiversity co-benefits, fauna is not treated as a functional component of forests. This neglect threatens to undermine forest ecosystem function and service delivery as well as long-term forest carbon assimilation capacity and hence, ultimately, to compromise REDD+ objectives

Effects of new roads on environmental resource use in the Central Himalaya

Construction of roads into remote rural areas can improve livelihoods by reducing transportation costs, but may also have negative environmental impacts, such as increased deforestation. However, evidence of the effect of rural roads on household environmental income and reliance, as well as local level forest stand conservation is limited. This study, conducted in Mustang District in Nepal, contributes to answering the following questions: (i) what are the impacts of the establishment of rural roads on household environmental income and reliance; (ii) what are the determinants of environmental income and reliance, and how are they affected by road establishment; and (iii) what are the short-term impacts of the construction of a rural road on local forest conservation? Following the Poverty Environment Network (PEN) methodology, income data from 176 randomly-sampled households were collected in 2006 from two similar Himalayan villages, Lete and Lulang, and again in 2012 after a new road was constructed in 2008 in Lete. Forest strata data were collected in Lete through permanent sample plots (n = 59) measured in 2005 and 2010 and used to estimate stock change (before and after road construction), annual increment and annual wood extraction. Results show that the new road had significant positive effects on absolute household environmental income, but negative effects on reliance as other income options became available. Wood product extraction levels remained below increment levels, indicating that the road did not (yet) have negative implications for local forest conservation
