The present study was undertaken to characterize the bushfire regime and the climatic factors influencing its propagation in the Bounkani region. Thus, this work analyzes the spatio-temporal dynamics of fires and the relationship between climatic variables and pyrological variables. First, it exploits time series of active fires and burned areas from MODIS Active fires (MCD14ML) and MODIS Burned area (MCD60A1) data for the period from 2000 to 2017. The methodology is based on the evaluation of seasonality and fire occurrences, and on the spatio-temporal evolution of fires. The results obtained indicate that, on average, the fire season occurs between the months of November and March, generally corresponding to the dry season. Also, the number of fires and the area burned follow a decreasing trend during the 17 years of study. The months of December and January recorded the highest peaks of burned areas and fire outbreaks respectively. Finally, the analysis of the dependence between climatic variables and pyrological variables by the Pearson correlation method showed the influence of climatic parameters in the outbreak and spread of bushfires in the study area. Precipitation and relative humidity are the best predictors with a negative influence on fire activity, while the positive predictors remain temperature. These variables directly impact fire regime in general. The results of this study will assist policy makers and managers in decision making for the implementation of fire control strategies.

Home garden, the name itself clarifies its meaning any garden that is belonging to home which can be anywhere at the front, behind, or in any fallow land. The reason why home garden and its diversity were studied is get access to the ethnobotanical study of the species and knowledge among people regarding the home garden could be more lighten up. A survey was conducted from October (2019) to January (2020). Among the surveyed fifty households, the type of home garden dominated was front type ranging from 45-700m2 whose management and diversity were changing as per the gender. Altogether of 108 species were collected in a home garden belonging to 45 families, 34 species were found to be common. The representative families Leguminosae and Asteraceae rank on top followed by Moraceae, Brassicaceae, Poaceae, and so on. Despite the result concluding the most diversified crops, the home garden of Sunsari district itself carries a wider range of diversity from fruits, vegetables, spices to economically useful species like ornamental plants and fodders. With the studies and knowledge accounted, it can be concluded that pursuing a home garden not only revalues our health and environment but also preserves a hundred ages of traditions.
