Upgrading all slums in Lagos by 2030 will an ambitious task, given that more than 70% of its residents resides in slums. Furthermore, there is no recent study identifying neither the slums nor their temporal growth/development pattern in Lagos that can backstop any slum management initiative. This study aims to contribute by applying object-based image analysis and intensity analysis to map and link patterns and processes of slum growth in Lagos. RapidEye imagery from 2009 and 2015 were used to create maps for each time point for six land use categories (water, vegetated area, open space, road, slum, and other urban). Intensity analysis was applied to quantify the annual intensity of changes at the category and transition level. An overall accuracy (and kappa coefficient) of 94% (0.9) and 89% (0.86) were achieved for the 2009 and 2015 land use and land cover maps, respectively. This study showed that slums in Lagos have increased spatially during the time interval studied, with a total net gain of 9.18 square kilometers, influenced by the increase in population, mainly due to in-migration to Lagos. However, this study also revealed that slums were actively losing and gaining land area between 2009 and 2015, with an annual gain and loss intensity of 10.08 and 6.41, respectively, compared to the uniform intensity of 3.15. The gain was due to poor maintenance of buildings and encroachment onto available spaces (water and open space), while the loss was attributed to gentrification and demolition processes. A systematic process of transition was observed between slums and other urban (and open space) areas in the interval studied, and this process was mainly influenced by the Lagos state government. This analysis is crucial for designing policy interventions to manage slum growth in Lagos.

This study investigated the local level impacts of climatic and non‐climatic factors on the agricultural land‐use dynamic in rural northern Ghana. Data was collected by means of household questionnaires and interview. The data collected relates to farmer's knowledge about climate change, response to the impact of climate change, dynamics in the area cultivated for crops, and the climatic and non‐climatic factors that affect agricultural land‐use dynamics. The data collected was subjected to simple descriptive statistics and chi‐square tests. Farmers indicated that the weather patterns have affected their cropping activities. Delay in the start of rainfall, fluctuation and cessation before the growing season ends have affected them. Also, inadequate access to farm inputs has affected them. In the face of unfavourable conditions, the farmers may respond by increasing or decreasing the land area cultivated for some crops, they may continue to cultivate their crops, or they may abandon the crop(s) for the season. Jobs outside of the farm are being taken up to support household needs. Climate change has been interacting with non‐climatic (socio‐economic) factors, and a holistic approach would be the best to address the local or regional change. Intensification of research within the study region and nearby regions would improve preparedness for future local/regional change.

This study investigated the influence of gender (sex) on the view of people towards the impact climate change on human health in south-west Nigeria. Data were collected by means of semi-structured questionnaire from impartial sampled males and females in Moba Local Government Area of Ekiti state, Nigeria. Using descriptive statistics and chi-square test, the collected data were analysed for (i) gender variation on the respondent's perception about climate change, (ii) gender variation in the perception of the respondents as regards the impact of climate change on human health, and (iii) association between sex type and perception on the impact of climate change on human health (malaria, disability, displacement, flooding, and cholera). Males and females showed comparable knowledge about climate change and its impact on human health, but males were slightly knowledgeable. In some aspect, gender showed significant association (p ≤ 0.05) with respondent's view on the impact of climate change on human health. Females showed better awareness as regards climate change contributing to malaria, while males are better aware as regards climate change contributing to flooding. Important concern revealed in this study is the low public awareness on the indirect health impact of climate change. Hence, continuous enlightenment of people on the various health impacts of the changing climate is recommended.
