Paper short abstract:
The study inferred a good corroboration between the data of climate and LULC and the indigenous views, and the information could be used in a participatory approach to assess the impact of environmental change on an important service of ecosystems such as fresh water resources.
Paper long abstract:
This investigated whether the perception of rural population on environmental changes - climatic condition and land use / land cover change (LULCC) in the woodland savanna and rain forest zones of Southwestern, Nigeria can be used to evaluate water resources potential in the region. LULCC was conducted using orthorectified Landsat multi-temporal imagery for 1970/1972, 1986/1987, 2000/2001 and 2006 using maximum likelihood classification and change detection techniques. The results showed a decrease in the forest area and an increase in built-up and cultivation/others (open space, bare land, grassland) areas. Between 1972 and 2006, forest reduced by about 50% while built-up areas increased by about 300%. A Participatory Learning Approach (PLA) involving indigenous population was conducted to assess their perceptions in the region on LULCC, the drivers of change, and the associated risk and local adaptation measures. The results revealed that changes in climatic and LULC in the last 30 years and various anthropogenic activities are the factors responsible for declining in surface water in the region.
Indigenous populations-vegetation-climate relationship in the past: what can this teach us about sustainable vegetation use in the present?
