“…Washington State Department of Ecology [20] reported a conductivity of 56,000 μScm −1 for sea water and stated that conductivity is an indirect index of water hardness. 6 -25 μScm −1 was reported for conductivity in Cross River System [21], 44 -96 μScm −1 for River Oshun [22] and 46 -96 μScm −1 in the upper Niger River [23], respectively. Emmanuel [18] reported a conductivity mean value of 27500 μScm −1 for wet season in Lagos Lagoon and 51,400 μScm −1 for dry season because of the lagoon proximity to the sea.…”

Some physicochemical parameters like temperature, transparency, dissolved solid, suspended materials, turbidity, conductivity, pH, total alkalinity, dissolved oxygen, nitrate, phosphate and salinity of water samples collected at Lekki Lagoon from November 2010 to September 2012 were evaluated. Fifteen locations were selected for water sampling according to the activities that took place in the lagoon. Physical water quality parameters such as temperature, transparency, total dissolved solids and total suspended solid showed strong seasonal and spatial fluctuation. Parameters like conductivity, pH and total alkalinity had relatively constant values among stations though they varied seasonally. Dissolved oxygen, nitrate and phosphate values were within permissible range for fish. Higher salinity values were recorded in wet seasons than dry seasons suggesting that salinity variation at Lekki Lagoon was due to salt incursion from the adjourning Lagos Lagoon and Mahin Creek during rainy season rather than evaporation factor. Salinity range of 1.70 -6.00 psu recorded in this study also shows that Lekki Lagoon is tending towards brackish and this may affect the ichthyofauna composition of the lagoon.

“…For both Mali and Nigeria, more than half of the articles for each country related to the food sector, ranging from smallholder farmers in Mali [ 57 ], to articles on specific drought-tolerant crops [ 77 ] and farmers of fruits and vegetables in Nigeria [ 4 ]. In addition to crops, there were several articles in this category on fishing and aquaculture [ 7 , 9 , 49 ] as well as livestock [ 15 , 17 , 24 , 49 ].…”

People affected by conflict are particularly vulnerable to climate shocks and climate change, yet little is known about climate change adaptation in fragile contexts. While climate events are one of the many contributing drivers of conflict, feedback from conflict increases vulnerability, thereby creating conditions for a vicious cycle of conflict. In this study, we carry out a systematic review of peer-reviewed literature, taking from the Global Adaptation Mapping Initiative (GAMI) dataset to documenting climate change adaptation occurring in 15 conflict-affected countries and compare the findings with records of climate adaptation finance flows and climate-related disasters in each country. Academic literature is sparse for most conflict-affected countries, and available studies tend to have a narrow focus, particularly on agriculture-related adaptation in rural contexts and adaptation by low-income actors. In contrast, multilateral and bilateral funding for climate change adaptation addresses a greater diversity of adaptation needs, including water systems, humanitarian programming, and urban areas. Even among the conflict-affected countries selected, we find disparity, with several countries being the focus of substantial research and funding, and others seeing little to none. Results indicate that people in conflict-affected contexts are adapting to climate change, but there is a pressing need for diverse scholarship across various sectors that documents a broader range of adaptation types and their results.

“…In Nigeria, fish products can be drawn from three major sources such as aquaculture, frozen fish (through importation) and from the natural waters (wild). The wild sources are categorized into industrial and artisanal (Akinrotimi and Edun, 2013). Fish represents an important dietary element and one of the few sources of animal protein available to many Nigerians (FAO, 2017).…”

The Fisheries sector despite being an important source of livelihood for the majority of riverine households, has been plagued by a number of problems. The study therefore determined fishing inputs and challenges associated with artisanal fishing in Ibi Local Government Area, Taraba State, Nigeria. Random sampling technique was used to obtain data from sixty (60) artisanal fishers from each of the four major fishing wards (Ibi town, Nwonyo, Sarki kudu and Dampar) through structured questionnaire and scheduled interview. Data obtained were analyzed using descriptive statistics (frequency distribution and percentage) and inferential statistics (Chi-square and Pearson Product Moment Correlation (PPMC) at p<0.05 significant level. The result showed that majority of the fish artisans were male (93.3%), married (69.5%), had formal education (52.3%), have over 21 years of fishing experience (34.7%), fish in the evening(55.2%) and spent 6-10 hours on water while fishing (67.4%). Artisanal fishers used gill net (26.4%), plank canoe (77.8%), paddle (70.3%), gura net (34.3%), cast net (33.1%), crew members (59.8%) as inputs for fishing. High cost of fishing inputs (=3.98), problem of theft (=3.70), lack of capital (=3.54), post-harvest losses (=2.83), poor sales (=2.44), poor catches (=2.41) and inefficient fishing gear (=2.28) were challenges faced by the artisanal fishers. Significant relationship existed between fishing inputs and challenges associated with artisanal fishing at p<0.05 level. It was recommended that soft loans should be provided to artisanal fishers by the government at low interest rate for procurement of fishing inputs and fish artisans in the community should be encouraged to form fisheries cooperative society to mobilize or pool their financial resources in order to ameliorate the constraints imposed through lack or inadequate finance.
