Tree knowledge and livelihood activities in a changing environment: views from smallholder farmers in Kosti, Sudan by Kalame, F.B., Luukkanen, O., Elsiddig, E.A., Glover, E.K.

“…The accelerated loss of forest vegetation is often perceived to result from increased unsustainable exploitation by poor rural populations for their livelihood needs. To explore this critique, we examined smallholder farmers' (SHFs) views on the management and utilization of trees for livelihood improvement and environmental protection. …”

Road and landscape features affecting the aggregation of ungulate vehicle collisions in southern Sweden by Sjölund, Magnus

“…Accident numbers are steadily growing but the trends are not well related to the changes in ungulate population sizes or hunting bag statistics. Authorities ask for more efficient mitigation strategies, but this require a good understanding of where and why UVC occur more frequently in some areas compared to others and which factors that affect these aggregated patterns. …”
