Spatial-temporal coupling of malaria vector habitat suitability and biting probability por Aduvukha, G.R., Abdel-Rahman, E.M., Mutanga, O., Odindi, J., Tonnang, H.E.Z.

“…Specifically, relevant remotely sensed data, climatic and topographic variables, and presenceonly malaria vector data were integrated into MaxEnt (maximum entropy), an SDM to assess the distribution of malaria vectors. Subsequently, additional variables such as the modelled malaria vector presence, human availability, confirmed insecticide resistance and bed net usage were incorporated in fuzzy logic rule-based techniques to assess the spatial and temporal biting risk probability of these vectors from 2000 to 2018. …”

Spatial prediction of soil organic carbon stocks in Ghana using legacy data por Owusu, Stephen, Yigini, Yusuf, Olmedo, Guillermo Federico, Omuto, Christian Thine

“…Soil organic carbon (SOC) is a major driver of the multiple functions of soils in the delivery of ecosystem services.
