In most studies on flood risk in Nigeria, priority is given to urban flood risk than rural flood risk. Smallholder farmers who mostly inhabit rural areas and flood plains are known to be at great risk of flooding, but to date, there have been no studies on the impacts they experience and how they cope with these impacts.
To establish the existence of significant change in precipitation in the study area, statistical analysis of precipitation data was conducted using linear regression and non-parametric Mann Kendall test. Landsat satellite images for 1986, 2003 and 2016 were obtained from the United States Geological Survey’s (USGS) website and used to collect and analyze data related to land use.
To determine flood risk in the context of land use change, the HEC-HMS model version 3.5 was used. Land use maps corresponding to 1986, 2003, and 2016 LULC conditions were analysed and prepared for the calculation of CN values using Soil Conservation Service (SCS-CN) method. CN map was prepared by integrating the maps of hydrologic soil groups and land use in ArcGIS software.
Based on selected morphological parameters, a flood risk map was developed for the study area. The morphologic flood risk showed that most parts of the basin face moderate flood risk. Higher runoff values were observed under 2016 LULC conditions mainly due to intense deforestation relative to those of 1986 and 2003. The results indicated that runoff and peak discharge are significantly affected by deforestation instead of changes in the rainfall pattern. Flood inundation maps of the study area were prepared for the flood events of 2012 and 2015. Maximum depth for the 2012 and 2015 flood events was calculated as 10.58m and 7.39m, respectively.
The socioeconomic aspects of the research were conducted using household survey method. Using snowball sampling techniques, 400 flood-affected households were selected. The results show that the adaptive capacity of smallholder farmers in the study area remains very low and hampered by several factors such as poverty and weakened social networks. The synopsis of the examined variables leads to the following conclusion: Instead of climatic factors – as one indicator of vulnerability – it is social inequality and poverty in the region as well as the structural economic differences between various groups that mainly drives vulnerability in the study area.
Scale dissonances between local and world heritage : the rural landscape of the Palladian villa
(2021)
This research critically analyses the visual representation of the Palladian villa landscape as UNESCO World Heritage. I bring to light certain dissonances around the understanding of this landscape as heritage between global and local perspective. I have explored the ways in which the rural landscape of the Palladian villas is produced by ICOMOS experts, local institution and inhabitants in the contemporary context of the suburban areas of the Veneto region in Italy. Dissonances are arising when the landscape transforms and the visual integrity, or the iconic image of the landscape get lost. I observed that, the loss of the visual integrity, considered as negative by ICOMOS experts, gives space to peculiar heritage social practices from below.
I am problematizing two main aspects of the conservation scheme of this site: the selective visual representation of history and the musealization of agriculture for touristic proposes. I am exploring the potential of reframing and renaming the conservation scheme of the World Heritage Site. I suggest using inhabitant’s visual representation to reframe the UNESCO management plan and considering the peculiar local agricultural practice as a “continuing cultural landscape”. I interpret my empirical and theoretical contribution as a semantic shift in the way the Palladian rural landscape is understood as World Heritage toward an inclusive and situated heritage conservation that extend beyond expert’s conservation philosophies. The research contributes to the deconstruction of modern notions of rural landscape and heritage in the field of heritage studies and landscape conservation especially within the implementation of the World Heritage Convention.
