Agroforestry coffee production increased by native shade trees, irrigation, and liming

Agroforestry systems usually include a high density and diversity of shade trees. Such systems often have a large diversity of fauna and flora and provide local and regional ecosystem services. Shade trees are, however, being removed to increase crop production in many tropical regions. There is little knowledge on the effect of shade trees on crop production in the context of trade-offs with other management practices. We therefore compared the benefits of exotic versus native shade trees on coffee production. We evaluated the importance of shade tree management for crop production in the context of management practices. Management practices included fertilization, liming, coffee pruning, weeding, and irrigation in 113 coffee agroforests in Kodagu, India, over a wide range of shade tree density, tree species diversity, and shade cover. We studied, in particular, Grevillea and non-Grevillea shade trees, the latter including mostly native tree species. Results show that a rise of 100 non-Grevillea shade tree per hectare increased production of berries by 5.6 % and larger beans by 6.25 %. Irrigation and liming increased berry production respectively by 16 and 20 %. These management interventions are likely to offset the relatively small negative effect of reducing shade density of non-Grevillea trees on coffee production. Recommendations based on an understanding of shade tree management alone can be misleading with regard to crop production.
Unlocking the potential of private finance for forest and landscape restoration

Private finance is necessary to scale forest and landscape restoration to deliver global commitments, yet finance levels remain insufficient. To understand why funding remains low despite growing interest, we conduct semi-structured interviews with financial actors and restoration finance practitioners to examine what incentives and barriers corporations and asset managers experience in financing restoration, and what type of restoration projects and regions different finance actors are likely to fund. Next, we assess how current financial barriers might be overcome. We find that there are market incentives for corporate entities to finance restoration for carbon drawdown, sustainable branding, and to promote sustainability in supply chains. Conversely, asset managers face strong barriers as projects are deemed high risk and with low prospects for sufficient return on investments. Through enhanced markets for restoration benefits, complementary public policies, and financial instruments, private finance for restoration can be scaled for a wider variety of restoration projects.

According to its advocates, an ecosystem‐services‐based approach to conservation will engender greater public support and produce more durable victories. Here, we identify three potential opportunity costs associated with such an approach: (1) diminished attention to protecting rare, localized species (the night parrot effect); (2) diminished attention to protecting wild, remote areas (the proximity‐to‐people effect); and (3) an emphasis on restoration projects near urban areas rather than the protection of relatively intact ecosystems (the rise‐of‐restoration effect). We encourage scientists and conservation practitioners to undertake the necessary monitoring and research to determine the magnitude of these opportunity costs.
Are patterns of fine-scale spatial genetic structure consistent between sites within tropical tree species?
Smith, James R.; Ghazoul, Jaboury; Burslem, David F.R.P.; et al. (2018)
PLoS ONE
Documenting the scale and intensity of fine-scale spatial genetic structure (FSGS), and the processes that shape it, is relevant to the sustainable management of genetic resources in timber tree species, particularly where logging or fragmentation might disrupt gene flow. In this study we assessed patterns of FSGS in three species of Dipterocarpaceae (Parashorea tomentella, Shorea leprosula and Shorea parvifolia) across four different tropical rain forests in Malaysia using nuclear microsatellite markers. Topographic heterogeneity varied across the sites. We hypothesised that forests with high topographic heterogeneity would display increased FSGS among the adult populations driven by habitat associations. This hypothesis was not supported for S. leprosula and S. parvifolia which displayed little variation in the intensity and scale of FSGS between sites despite substantial variation in topographic heterogeneity. Conversely, the intensity of FSGS for P. tomentella was greater at a more topographically heterogeneous than a homogeneous site, and a significant difference in the overall pattern of FSGS was detected between sites for this species. These results suggest that local patterns of FSGS may in some species be shaped by habitat heterogeneity in addition to limited gene flow by pollen and seed dispersal. Site factors can therefore contribute to the development of FSGS. Confirming consistency in species’ FSGS amongst sites is an important step in managing timber tree genetic diversity as it provides confidence that species specific management recommendations based on species reproductive traits can be applied across a species’ range. Forest managers should take into account the interaction between reproductive traits and site characteristics, its consequences for maintaining forest genetic resources and how this might influence natural regeneration across species if management is to be sustainable.
