| dc.description.abstract | Like other regions of Guinea Bissau, the economy of the Cacheu region is not very diversified and is dominated
by cashew nut cultivation. As the country's leading production zone, with more than 30% of the national cashew nut
production, the region has seen the disappearance of a large part of its natural ecosystems, especially the Elaeis guineensis
parklands, despite their socio-economic importance. It is in this logic that this study is devoted to the analysis of the dynamics
of the Elaeis guineensis parklands in the Cacheu region over the last fifteen years. To do this, terroir transects and mapping
were carried out in order to identify and see the evolution of the landscape units. Surveys on the dynamics of the parklands and
other landscape units have been carried out. The combination of these methods revealed a strong disappearance of Elaeis
guineensis parklands and natural vegetation. Between 2003 and 2018, an average increase of 224 ha of cashew plantation by
village terroir was noted, already causing the disappearance of 153.26 ha of Elaeis guineensis parklands on average. The main
cause of this disappearance is the uncontrolled expansion of cashew nut plantations. In addition to this, there are many cuts of
palm tree for house construction, habitat expansion, bad exploitation practices and climate deterioration. This pressure on
Elaeis guineensis parklands is gradually leading them to disappear in favour of cashew nut monoculture. It is for this purpose
that special attention is being paid to these ecosystems, which are of paramount importance to the livelihood of the local
population. | en_US |
