Abstract:
ABSTRACT
Plant diversity has a broad socio-economic and agro-ecological role in home
gardens, including food production and a wide range of other products. The recent
study was conducted in eight villages of four unions under Kishoreganj and
Saidpur upazilas in Nilphamari district to explore the tree species diversity and its
impact on socio-economic condition of the farmers. The assessment was carried
out using a purposive random sampling process. Based on the accumulation of 60
households from marginal, small, medium and large categories, information was
concentrated. It identified a total of 1871 trees, representing 23 families.
Determination of the relative abundance of the tree species showed that 21.17% of
homestead agroforestry is Mangifera indica followed by Artocarpus heterophyllus
(16.41%) and Cocos nucifera which occupies 8.93%. The Shannon-Wiener index
(H) was used to evaluate the diversity of the trees and the evaluation showed that
the area’s diversity of tree species was 2.723. The Shannon-Wiener index (H)
varies from 1.22 to 2.72 according to plant categorization. The diversity of tree
species was positively influenced by livelihood conditions of farmers but
adversely affected by gender. Socio-economic aspects of farmers had direct
impact on livelihood status, farm size, homestead size, annual income and
organizational participation. The results of this study may contribute to modifying
agroforestry programs for the implementation of future tree planting activities in
different economic and environmental circumstances for different target
populations.
