    Abstract: The study investigated the socio-economic impacts of the 2012 flooding in the riverine areas Isoko south Local Government area, Delta State. Two communities Oleh and Aviara which were greatly affected by the flood event were selected for the study. Both purposive and simple random sampling techniques were adopted in the survey. A total of two hundred questionnaire were distributed to household heads, famers, community and religious leaders, one hundred per community. Impacts on building/household property, financial cost of damage, impact on small farm holders, damage on school infrastructures, diseases distributed were used as impact indicators. The study showed that displacement of family members for a period of 3-4months recorded the highest impact with Oleh and Aviara communities scoring impact level of 34% and 36.6% respectively. This was followed by submergence of farmland/lost of valuable household property, 27.7% in Oleh community and 23.6% Aviara community. Death/major injury during the flood event recorded least impact of 8.5% in Oleh and 3.2% in Aviara communities. On the average these impacts were valued at between one and two million naira (N). Analysis of impact on small farm holders showed that monthly income groups between 〈 50,000 and 100,000 naira(N) were worst hit by the flood event. These groups are mostly subsistent farmers including snail farmers, poultry owners. The study revealed that schools were closed down for a period of 2-3months while collapsed of bridges was a leading cause of disruption in school activities with impact scores of 22.2% and 18.8% in Oleh and Avaira communities respectively. Analysis of disease distribution showed that malaria fever ranked highest, 33.1% in Oleh and 41.9% in Avaira respectively. This was followed by Diarrhoea, 22.6% in Oleh and Typhoid fever, 22.1% in Aviara. Bearing the losses was a common response approach to the flood disaster in the sampled communities with scores of 30.9% in Oleh and 27.6% in Aviara community. Structural modification ranked second with impact score of 16.5% in Oleh and migration to alternative location 16.3% in Avaira. Least response approach was construction of Monkey Bridge, 4.2% in Oleh and 4.1% in Avaira. Analysis of underlying cause of vulnerability showed that over reliance on government intervention thus doing little was main cause of vulnerability in Oleh, 25%, while in Avaira the main cause of vulnerability was attitude/cultural belief, 20.4%. The geographical locations of these communities also increase their vulnerability to flood by 22.9% in Oleh and 19.4% in Aviara. Result of student t test at 0.05 level of significance showed that the impact of the 2012 flooding in study area was similar in terms of damage to physical property, financial cost of impact, damage to school infrastructures and disease distribution. However, significant variation was observed in the two communities in terms of impacts on small farm holders. The study recommends land zoning in the framework of urban planning and regulation of urban development with a view to reducing the vulnerability of future flooding especially in the light recent global warming and climate change.

    Abstract: The present study aimed to investigate the effects of hydrologically induced environmental problem in Benin City and how communities (considered as non-state actors) can be sustainably integrated/participate in monitoring of environmental change, disaster preparedness, post disaster management mechanisms and influence water resources development/management decisions. The study focused on the seasonal flood events of years 2016 and 2017. The study showed that the impacts of flooding in Benin City ranges from submergence of physical infrastructures, loss of agricultural lands/ farms. Using the Focused Group Discussion and Interview methods, 61.9% of flood affected persons agreed that their houses were submerged, 80.5% indicated that their farms, including fish farms, piggery, snail farms, crops and poultry were damaged by floods, 9.6%, indicated having experienced food stock losses due to floods. Most common diseases/sicknesses experienced were diarrhoea (27%), malaria (37%); cough (20%), while sickness due to snake bite was the least (4%). Fe and fecal coli form count values were high during seasonal flood event. Most of the hydraulic regulation projects have failed mainly due to poor feasibility study, inadequacy of hydrological data, non-involvement of relevant stakeholder and the complete absence of community based groups during engineering construction works. The study proposed a State-Non-state actors Integrated Model, which will be registered as a Corporate organization to plan and monitor environmental changes relating to climate change, flood and gully erosion disasters and with the active involvement of NEMA, SEMA, LEMA and other related agencies and NGO. Depending on the size of each Local Government Area in Benin, the proposed committee will comprise of 25-50 members. The study recommends capacity building of members in the form of training and re-training in the areas of early warning, preparedness, adaptation, emergency plan, data collection method/analysis, writing of research grants proposals to fund the activities of the committee and monitoring for environmental changes.

    Abstract: The study examined the dynamic nature of water balance parameters over Kano town, a semi-arid environment and impact of Linacre derived potential evapotranspiration method on the supplementary irrigation water needs of selected crops. Monthly Rainfall and Temperature data were collected from the Nigerian Meteorological Agency, Lagos for the period 1953-2012. The study observed that there is a steady decline in annual precipitation over Kano from the first decade (1953-1962) to the fifth decade (1993-2002), after which there was a sign of weak recovery in the last decade (2003-2012). For water loss through potential evapotranspiration, there was a steady rise from the first decade (1953-1962) to the fifth decade (1993-2002), and then followed by a sudden decline in the last decade (2003-2012). The total average of water storage on the other hand, first experienced a rise between the first two decades (1953-1962) and (1963-1972), followed by a steady decline, up until the fifth decade (1993-2002) and finally a rise in the last decade (20032012). The total average of soil water deficit experienced a steady rise between the first and the fifth decades (1953-1962) to (1993-2002), this was followed by a decline in the last decade (20032012). Finally, the total average of water surplus experienced a steady decline between the first and the fifth decades. The observed decline in precipitation, storage, and water surplus, and the rise in water loss from potential evapotranspiration and soil water deficit, suggests that there have been changes in the climatic pattern over Kano and this could be seen in the supplementary irrigation water needs of Tomato/Cabbage/Carrot.

    Abstract: The present study assessed solid waste management practices and impact on Ala River water quality in Akure, Ondo state, Nigeria. The primary data were obtained through field observation, interviews and questionnaire while secondary data were obtained from desk review of use of journals, articles, seminar papers, internet sources, government official publications. Simple random sampling technique was used to obtain required information for the study. Results showed that 37.8% of the solid waste generated is of vegetable and food remains origin, polythene and plastics wastes are 28.3 and 19.1% respectively. The result shows that 66% of the respondents do not segregate their waste before disposal and knowledge on waste recycling was low. The major limitations at household and community levels are inadequacies of collection and storage facilities. Similarly, perception towards municipal solid waste management was generally low. The major effects of poor waste management in the study area were land pollution, flooding and water pollution of River Ala in Oke-Aro district of the study area. This is evident in the high levels of turbidity, biochemical oxygen demand, dissolved oxygen and fecal coliform bacteria of the water quality of River Ala, all of which suggests the presence of microbial organisms which may have been introduced to the water body via diffuse pollution aided by urban storm water runoff and leachate. It is therefore recommended that government should provide more waste receptacles in at both residential and commercial areas across the study area. Finally, government should consider waste-to-wealth initiatives. The first step in realizing this would involve encouraging the residents on the need to sort their waste before disposal and, secondly, waste characterization to determine the energy potentials of waste streams in the study area.

    Abstract: The study investigated the effects of rainfall and temperature variability on crop water requirements of selected food crops in the Sokoto-Rima River Basin, Northwest of Nigeria. Rainfall and temperature datasets were obtained from the Climatic Research Unit (CRU) TS 3.21 of the University of East Anglia, Norwich, for a period of 70 years (1943-2012). The suitability of CRU datasets were verified by correlating the datasets with measured rainfall data of Yelwa synoptic station, from the Nigerian Meteorological Agency. Selected food crops were used for estimating supplementary irrigation water needs in the River basin. Results of Mann-Kendal, Spearman’s Rho and linear regression tests showed strong evidence of increasing annual temperature and potential evapotranspiration with corresponding decrease in rainfall amounts, especially in the northern parts of the basin which houses big irrigation projects and dams such as the Goronyo Irrigation and the Bakolori Dam and Bakolori Irrigation Project. This will impact on the water availability within the basin, through reduction in surface and ground water supply for ongoing irrigation and other water resources projects. Water requirements for selected crops were modeled to ascertain crop sensitivity to climatic variability which will aid in the design of supplementary irrigation water needs models. Results showed that even in the rainfall months, supplementary irrigation of varying quantity is required to complement rainfall, most especially, in the northeast of the basin. Surprisingly, the month of May which marks commencement of rainfall, recorded the highest water need and this has implication for agriculture yields in the region.
