“…South Africa is also rich in wetlands, which are natural fabrics providing a range of ecosystem services. Unfortunately, 35% to 60% of South Africa's wetlands is lost or severely degraded [42]. Also, there are prevalently high rates of atmospheric emissions from both household and industrial origins [43].…”

The ongoing exponential growth of human population poses a risk to sustainable development goals (SDGs). Unless we understand the drivers of this growth and inform policy development accordingly, SDGs would remain a dream. One of the old theories of population growth known as the Malthusian theory predicts that resource availability drives population growth until a certain time when population growth outrun resource availability, leading to all sort of crises summarized as Malthusian crisis. Although the link between economic growth and population has been widely investigated while testing the theory, little is known about environmental and social factors potentially driving population growth. Here, because of various crises of our time recalling the Malthusian crisis, we revisited the theory by fitting structural equation models to environmental, social and economic data collected over 30-year period in South Africa. None of the social variables tested predicts population growth. Instead, we found that biodiversity (species protection index) correlates positively with population growth. Biodiversity provides various resources through ecosystem goods and services to human, thus supporting population growth as predicted in the Malthusian theory. However, we also found that this population growth may lead to conservation conflict as we found that biodiversity habitat (wetland area) correlates negatively with population growth, thus raising the compromising effect of population growth on life on earth. What’s more, we found a significant link between economic growth measured as GDP and population growth, further supporting the Malthusian prediction. Overall, our study re-affirms the value of biodiversity to human and suggests that the Malthusian theory should continuously be tested with predictors other than economic.

The wetland ecosystem is among the most important ecosystems globally. It is a source of ecosystem services that can contribute to the income and means of livelihood for communities living near the vicinity of wetlands especially in developing countries. Ethiopia is among the least developing countries in Africa where many communities around the wetlands depend on ecosystem services for their livelihoods. However, these wetlands are being degraded both by anthropogenic and natural factors. The objectives of the study were to assess the status of the major wetlands and their contribution to the livelihoods of communities in South Wollo Zone of Amhara Regional State located in North-Eastern Ethiopia. Districts in South Wollo with wetland potential were selected purposely in collaboration with Zonal Agricultural Office experts. A multistage sampling technique was used to select 114 respondents living around the wetlands for the interview. In addition to this, three focus group discussions and key informant interviews were conducted to gather data focused on types of wetlands, major provisioning ecosystem services, and major threats to wetlands. In the study area, 9 natural and 3 manmade major wetlands were identified. These wetlands have provisioning ecosystem services such as food production; source of grasses for animal feed; ceremonial activities; roof making and handicrafts; and water for drinking, livestock watering, and irrigation which are the major sources of livelihoods. Though these wetlands have important roles in livelihood, they are highly affected by settlement, conversion for agriculture, overgrazing, excessive water abstraction, deforestation, sand mining, pollution, invasive species, and climate change. Therefore, wetland management intervention plan should be prepared and implemented through a community-based restoration approach.

“…Therefore, with the ongoing human pressures and increasing climatic variability, the urgent need for tools (e.g., use of local organisms) for ecological health assessment is a priority in conservation efforts and efficient management of wetlands in developing countries (Kaboréet al, 2018). This is true for many tropical wetlands such as Asia, Africa, Latin America, and the Caribbean where continually changes in quantity and quality of wetland areas are receiving considerable attention (Sarkar et al, 2020;Adeeyo et al, 2022).…”

“…In Africa, most of the endangered species (e.g., amphibians, birds, mammals, invertebrates, and fish) and highly diverse natural habitats are confined in protected wetlands, and most of them are under anthropogenic disturbances (Clarkson et al, 2004;Camacho-Valdez et al, 2014;Arowosafe et al, 2019;Stephenson et al, 2020). For example, in South Africa, Adeeyo et al (2022); Sinthumule and Netshisaulu (2022) address the ranges of threats affecting wetland ecosystems functioning and provide guidelines for long term management. According to Adeeyo et al (2022), the current state of several wetlands across African countries calls for urgent attention.…”

According to Adeeyo et al (2022), the current state of several wetlands across African countries calls for urgent attention. The unclear management status linked to policy and legislation weaknesses and the scarcity of biological data and tools to monitor wetlands are central problems that need to be solved urgently by scientists and policy makers to avoid irreversible extinction of existing wetlands (Gumbricht et al, 2017;Kaboréet al, 2018;Stephenson et al, 2020;Adeeyo et al, 2022).…”

Birds, amphibians, fish, and macroinvertebrates are useful indicators of ecological conditions and ensure considerable conservation value and tools for decision making in management of wetland ecosystems. However, the use of these organisms to monitor wetland ecosystems has rarely been explored in Western Africa. Whereas, we are currently facing to growing multiple anthropogenic pressures and climate warming that impact negatively our wetlands and the biodiversity. Notably, there is an urgent need of cost-effective tools for wetland ecosystems health assessment in Burkina Faso. In this study, we examined the taxonomic composition of birds, amphibians, fish, and macroinvertebrates and explored their potential use for monitoring wetland ecosystems. From our findings, measures of taxa composition and diversity respond to the gradients of anthropogenic alterations. Our results revealed that the highest diversity of fish and macroinvertebrates taxa was recorded in protected sites, whereas the lowest diversity was obtained in degraded sites. Additionally, the findings showed a strong and positive correlation between macroinvertebrates taxa and key water variables, whereas fish taxa were strongly correlated to xylal (deadwood) substrates. Most of bird’s species were recorded in tree-shrubs, and amphibians of protected wetlands were distinguished by identifying indicator taxa through indicator value index. African wetland ecosystems and biodiversity may be sustainably preserved through responsive monitoring programs of wetlands by limnologists.
