Abstract: Slums and informal housing developments in Akure are growing at an unprecedented rate. It is on this basis that this work sets out to map out the indices of slum and informal housing development in Akure, Ondo State, Nigeria. High-resolution satellite data, as well as primary and secondary data, were used in the study. Based on collected data, ArcGIS 10.3.1 software was used to prepare a base map showing the existing land use, built up area in 1986, 2002, and 2019, and indices of slums, or informal housing in Akure. The indices were rated on a scale of 1–5 and the results obtained revealed that socio-economic indices [housing shortage, lack of affordable housing, high incidences of urban poverty, high incidences of rural or urban–urban migration and unemployment], institutional indices [poor enforcement of planning laws, unclear regulation and long procedures for building plan approvals, and lack of planning/development plans], political indices [inadequate provision of sites and services, tenure insecurity and eviction, and poor resettlement programme by the government] and environmental indices [high density of development and overcrowding, inadequate neighbourhood facilities and services, and inadequate sanitation] are most significant in the core and peripheral areas of Akure. The study recommends slum upgrading programmes oriented to the betterment of the current conditions of slum households and neighbourhoods and formal housing aimed at securing access to adequate housing for all, in particular the most vulnerable, promoting affordable and safe solutions and inclusive housing finance systems.

Abstract: The assessment of total hydrocarbon soil (THC) content of Rhizophora mangle and Nypa fruticans was investigated. Plant part of the studied plants (leaves, root, and stem) were collected from the studied forest. In each study area a 20 x 20m plot was delineated. Within each plot 10 trees were sampled randomly using stratified systematic analyzed sampling method. For the soil analysis, fresh samples were collected insitu with a soil augur weighed and placed in a sterile polythene bags and sent to laboratory, each location 3 replicates from each sampling plot were used for both locations. leaves, pieces of root and stem of red mangrove were harvested similar techniques were adopted for Nypa palm and placed in the cooler and taken to the laboratory for analysis. The collected samples were analyzed for THC in plant parts, THC and physicochemical parameters for soil and water. The result generated showed a significant variation of THC accumulation was more in root of Nypa fruticans than Rhizophora mangle roots. The leaves and bark of Rhizophora Mangle accumulated high concentration of THC. This study showed that higher productivity and litter fall in Rhizophora mangle is a mechanism to counter the effect of total hydrocarbon pollution in a polluted rain forest environment. Rhizophora mangle could be referred also as hyper accumulator due to its ability in accumulating the high amount of THC in leaves.

Abstract: Dry lands are traditionally used and managed by a pastoralist, characterized by variable precipitation, climate variability and water scarcity. Change in rainfall trend and variability’s lead to severe production deficit and decline the balance between pasture and livestock on which pastoral livelihood depends on. The study was undertaken to assess the variability and trends of rainfall in Borana pastoral area using monthly rainfall record for the period 1987-2016 of Yabello and Eel-wayye station. Rainfall variability analysis has been done using variability indices like, coefficient of variation, precipitation concentration index and Standard anomaly index. Trend analysis was carried out using Man-Kendall trend test 5% significance level. The coefficient variation of the study area for Yabello was 21.2%, while for Eel-wayye it was 53% which showed high inter-annual variability. The negative anomalies at Yabello station was 53.3% While in Eel-wayye station, revealed 56%. The analysis result indicted that the rainfall concentration index value ranged from 13.2 to 30.23 for the stations which shows moderate to strong irregularly rainfall distribution. The year 2006 was the most drastic and distinct-wide extreme drought episode in both stations, Except short rainy season at Eel-wayye station, the Mann–Kendal test shows not statistically significant (P<0.05). Increasing tendencies of drought during main rainy season and decreasing tendencies of drought during short rainy season and annually were observed in the study area. This threats the livestock production systems, which is the backbone of the pastorals livelihood. The study, suggests policy makers to develop other sustainable water sources for lowlands pastorals.
