“…That is, knowledge related to which crops to combine with tree species, how to combine species in agroforestry system and knowledge related to management techniques, so as to reduce negative effects (e.g., shading effect, competition for resources, such as water, nutrients, rain and light, and allelopathy [45,46]), are better handled by farmers of the semi-arid area. In addition, farmers in the semi-arid area had more agroforestry species on their farms than those in the sub-humid Sudano-Guinean region, although floristic diversity is known to be higher in Sudano-Guinean region than the Sudanian one [28,47,48]. This is consistent with the findings by Assogbadjo et al [49] that traditional agroforestry systems in the Sudanian region of Benin are more diversified in terms of species richness than in the Sudano-Guinean region.…”

Abstract:Building on farmer's agroecological knowledge to design environmental-friendly agricultural systems is crucial given the environmental impact of industrial agriculture. We investigated the drivers of farmers' knowledge of agrobiodiversity management and analyzed how farmers' knowledge and their current farming contexts may guide future farming systems in sub-humid (Bassila) and semi-arid (Boukoumbé) areas of Benin. We conducted structured interviews with 180 farmers and used generalized linear models and correlation analyses to understand the spatio-temporal dynamics of farmers' knowledge and perception. Land tenure, ecological conditions and sociolinguistic membership were the main drivers of farmers' knowledge of agroforestry systems, practices, species diversity and current farming systems. Sociolinguistic membership also significantly predicted farmers' knowledge of livestock management. Farmers in the semi-arid area were more involved in integrated crop-tree-livestock systems than those in the sub-humid area. However, all farmers indicated a willingness to adopt this integrated farming system regardless of socioeconomic and ecological factors. Farmer's knowledge of agrobiodiversity (crops, agroforestry species and livestock diversity) management was correlated with the involvement in integrated crop-livestock-tree and agroforestry systems. These findings provide insights into how farmers' knowledge can serve as basis in optimizing agricultural and livelihoods systems. Investigating the ecological, economic and social performance of the most desired OPEN ACCESSSustainability 2015, 7 6574 integration/diversification options using a system approach involving a co-innovation process can further our mechanistic understanding of farmers decision making process.

“…Areas where G. kola may find its climatic envelope are medium to high population density areas. So, as remarked on one hand by Sogbohossou andAkpona (2006, 2007), Santini (2013), Idohou et al (2014), Salako et al (2014), and Gbedomon et al (2015Gbedomon et al ( , 2016) that home gardens, botanical gardens in cities, urbanization through the green spaces and any other area in urban centers maintain the urban biodiversity and their remark aligns with the present findings. On the other hand, urban biodiversity is essentially influenced by human pressure (Sogbohossou andAkpona, 2006, 2007;Santini, 2013), giving more importance to the results that were obtained emphasizing the importance of the promotion of urban forestry and agroforestry.…”

A study was conducted to assess how well climate changes can help to conserve and restore Garcinia kola Heckel in the Protected Area Network (PAN) and in urban areas in Benin. To achieve this, occurrence data from GBIF was used and the environmental data from AfriClim was used in order to model the species' potential habitat under current and future climates. The maximum entropy modeling approach of MaxEnt was used with scenarios RCP4.5 and RCP8.5 for future predictions. Geographic information systems were used to establish the high confidence prediction areas (HCPA) for G. kola. Gap analysis was performed throughout PAN and municipalities with regard to the HCPA. Considering the climate envelop, results revealed that climate change prooved to have only positive consequences on the distribution of the species. Moreover, considering the HCPA, the percentage of municipalities that were suitable for the species is far above the percentage of PAN that was predicted as suitable (7.44% versus 0.93%). RCP4.5 and RCP8.5 indicated respectively 3.00 and 6.27% of PAN as positive climate change impact zones. As for the municipalities, it was respectively 13.60 and 17.60% of the total municipalities areas. Therefore, it is not worth relying only on PAN to conserve and restore the species, rather urban forestry and reforestation in PAN may be key actions to save this genetic resource. Further studies with regard to introduction of G. kola in urban areas and its use for reforestation are compulsory.

“…Recent work on agroecology and food sovereignty shows that multi-cropping intensive farming methods provide enough food from small plots and, at the same time, make the intensive gathering of wild fruits from well-developed woodland more compatible (Altieri et al 2012). This model also results in the protection and incorporation of wild plants into home gardens, such as Silybum marianum or Fragaria vesca, in order to consume them as fruit, vegetables or for medicinal purposes (Agelet et al 2000;Salako et al 2014). This would make intensive farming practices more compatible with the intensive management of wild resources.…”

The archaeobotanical record of 24 sites from the Neolithic period (5400-2300 cal BC) in the north-east of the Iberian Peninsula is evaluated. Remarkable amounts of data have recently been obtained for the early and middle Neolithic phases. Most of the studied sites were dry and they only yielded charred plant material. Among dry sites, several types of context were evaluated: dwelling areas, hearths, roasting pits and byres. Material was also analysed from a waterlogged cultural layer of one early Neolithic lakeshore site, La Draga. Quercus sp. (acorns), Corylus avellana L. (hazelnuts), Pistacia lentiscus L. (mastic fruits) and Vitis vinifera L. var. sylvestris (wild grapes) were among the most frequently encountered fruits and seeds. Their presence in the archaeobotanical record clearly maps their past ecological distribution in the region. There are differences observed between the charred dryland material and the waterlogged uncharred material. Wild fruits were mostly present in an uncharred state in La Draga. Therefore, their consumption could go unnoticed in dry sites when fruits were eaten raw or without roasting. Larger amounts of charred remains of certain wild fruits like acorns and hazelnuts found in mountain areas are highlighted as potential evidence of the regular practice of roasting, potentially indicating regional traditions. All in all, our results support an intensive wild plant use at least during the first 1,300 years of the Neolithic period. Evidence of wild plant food consumption becomes scanty towards the second phase of the middle and the late Neolithic (4th and 3rd millennium cal BC). This, however, might also be due to taphonomic reasons.
