“…However, only three or four economically important species are cultivated commercially ( Renuka, 1992 ). Domestication may also contribute significantly to national economies and in maintaining some degree of forest cover in heavily-exploited regions ( Mack, 2000 , Idohou et al., 2016 ) and reduce pressure on natural populations. Cultivation may also help to increase recognition of the importance of wild species, and encourage preservation and restoration of wild populations in their natural habitats ( Cuni Sanchez et al., 2011 ).…”

Rattans, or canes, are one of the most important non-timber forest products supporting the livelihood of many forest-dwelling communities in South and North-eastern India. Due to increased demand for rattan products, rattans have been extracted indiscriminately from the Western Ghats, a 1600-km mountain chain running parallel to the west coast of India. Extensive harvesting, loss of habitat and poor regeneration has resulted in dwindling rattan populations, necessitating an urgent attempt to conserve existing rattan resources. In this study, using niche-modelling tools, an attempt has been made to identify areas of high species richness of rattans in the Western Ghats, one of the mega-diversity regions of the world. We have also developed conservation values for 21 economically important and endemic rattans of the Western Ghats. We identified at least two to three sites of extremely high species richness outside the existing protected area network that should be prioritized for in situ conservation. This study emphasizes the need to develop strategies for the long-term conservation of rattans in the Western Ghats, India.

“…Biophysical variables such as population, elevation, slope, Land cover, wetland, distance to river, soil and distance to dwellings at the scale of Benin were used to assess their contribution to the performance of the models. Elevation, vegetation cover, watercourse, population, and wetland data were downloaded from the DIVA-GIS website ( https://www.diva-gis.org/gdata ) whereas soil data were downloaded at a resolution of 30 arcseconds from the African Soil Profiles Database ( https://www.isric.org ) ( Idohou et al . , 2017 ).…”

“…Such ENM and SDM approaches are currently widely used in biogeography, conservation biology and ecology (Stockwell and Peterson, 2001;Segurado and Araújo, 2004;Pearson et al, 2007;Elith et al, 2011). For examples, Fandohan et al (2015) modeled the vulnerability of protected areas of Benin to possible invasion of Lantana camara (invasive species native to South America) under current and future climates; Adjahossou et al (2016) assessed the effectiveness of protected areas through the prediction of potential favorable areas for the cultivation and conservation of some tree species of socio-economic importance in Benin; Idohou et al (2016) used niche models to identify potential spatial priorities for the conservation of wild palm species across West Africa; Gbètoho et al (2017) applied ecological niche models to predict the suitability and ability of some pioneer forest species to restore secondary forests in Lama forest reserve in Benin. All those studies showed the usefulness of the ENM/SDM approach for providing information that can derive in adequate strategies to conserve species, communities, biomes, and biodiversity as a whole at national, regional or more global scales.…”

Dialium guineense is a multipurpose species useful in many respects. It is used in agroforestry and the trade of most of its organs is source of income for rural populations. Despite the high interests of this species to populations, we do not know much about how its spatial distribution could be impacted by climate change and which strategies to implement for its sustainable use and conservation. In order to overcome these challenges, MaxEnt was used to model the ecological niche of D. guineense and different decision thresholds w ere used to interpret and classify the outputs. Climate will impact the distribution of D. guineense. Indeed under Africlim rcp 4.5 horizon 2055, the predicted stable areas of species distribution will be about 73% of West Africa when the threshold of the minimum training presence is considered and will decrease to 12% when the threshold of the maximum training sensitivity plus specificity is considered. Under Africlim 8.5 horizon 2055, the corresponding values for the stable areas of the species are, respectively 70 and 8% of the study area. In comparison with the global results of West Africa, in Benin, D. guineense will be less threatened by climate change. As strategies for sustainable use and conservation of the species, growing and introducing it in its favorable areas to account for its absence or low densities, is recommended. Also, building capacities to the users of the species so that they can grow it on their farms is recommended.
