“…The respondents reported that the weeds have reduced the water flow and caused blockage of channels. This view of the FGD discussants has been confirmed by several studies (Abubakar et al, 2016;Ndour et al, 2019;Zungum et al, 2019). The weeds have been affecting fishing activities because they affect water flows and fishing using nets and canoes.…”

“…On the other hand, focused on how typha grass is militating against agricultural productivity along Hadejia River. Similar studies in the area are those of Zungum et al (2019) and Salako et al (2016). However, the latter studied the impact of typha grass on biodiversity loss in the wetlands, while the former carried out a research on how typha contributes to wetland water loss and health risk in the wetlands.…”

Hadejia-Nguru wetlands is known as a joule of the Sahel as it is the major biodiversity reservoir of the Sahelian parts of Nigeria. However, series of impediment that follows the Sahelian drought of 1970s has been altering the ecosystem of the wetlands. The secondary succession of invasive weed that follow the habitat changes has altered the wetlands derived livelihood activities. This study examines the livelihoods constrain of the weeds as well as livelihoods derived from the weeds. Information on biodiversity timeline history, types of weeds that grow on the wetland site, the livelihoods activities derived from the weeds, and the livelihoods constraint of weeds were collected through interviews with key informants and focus group discussion. Three focus group discussions were conducted in six wetlands site communities, with participants including farmers, pastoralists, and other categories of wetland users. The qualitative information collected was analysed using grounded theory tool. The study identified 18 weed species that grow on the Hadejia-Nguru wetlands and discovered that the weeds are sources of raw materials for constructions, craft work, and fodder for animals among others. They also constitute the major constraints to livelihood activities such as fishing, transportation, irrigation, rainfed farming, and domestic water supply, among others. The study concluded that weeds are both a constraint and means of livelihood. Hence, the study’s hypothesis is that ‘’the impact of weeds on livelihoods diminish over time’.’ It is therefore recommended that all the beneficial weeds in the wetlands should be identified and utilized sustainably, while the growth of the bad ones should be controlled.

There is a sustained rise in incidence of cancer and toxicity related to chemicals exerting enormous burden to public health and biodiversity. Polycyclic Aromatic Hydrocarbons (PAHs) are mong such contaminants, precisely the sixteen-priority characterized by United States Environmental Protection Agency (USEPA). Therefore, this review is aimed at further elaboration about the 16 USEPA characterized PAHs and threat portend to public health and biodiversity. PAHs are a class of very stable organic pollutants produced most commonly, by incomplete combustion of fossil fuel and are formed when complex organic substances are exposed to heat. PAHs in great amount due to build up over time by bioaccumulation can be perilous: to human beings of all age and levels, aquatic organisms, amphibians and reptiles. The soil like the aquatic environment contains substantial quantity of PAHs since, atmospheric PAHs sediments on the soil due to dry and wet deposition, terrestrial organism are impacted if the soil is saturated with PAHs. Therefore, PAHs are a great source of trepidation for food safety, public health and biodiversity sustenance. Hence, tackling the spade of the menacing ubiquity of PAHs becomes necessary from its sources by encouragement of alternatives to petroleum fuels for machines and vehicles.
