Mining alters the natural landscape and discharges large volumes of wastes that pose serious pollution hazards to environment, human health agriculture. As a result, recent 2 decades have witnessed global surge in research on post-mining restoration, yielding suite techniques including physical, chemical, biological (also known as phytoremediation) combinations. Despite long history mining Africa, no systematic review has summarized advances restoration practices after disturbance. Thus, aim...
Abstract The Miombo, the most extensive tropical woodland formation of Africa directly supports livelihoods over 100 million people through provision many tree products and ecosystem services essential to both rural urban communities. While destruction Miombo has often been blamed on communities dwelling near forest resources, dwellers depend heavily various derived from woodlands. This paper highlights importance in people, potential threats this opportunities for its sustainable...
Soil characterization is a vital activity to develop appropriate and effective restoration protocols for mine wastelands while insights into the total content of heavy metals in soil an important step estimating hazards that may pose roles ecosystem. This study addressed following research questions: (1) To what extent do physico-chemical characteristics vary between waste sediments nearby forest soil? (2) Are concentrations high enough be considered as toxic? (3) present potential sources...
Mercury (Hg) pollution remains an environmental global concern due to its non-degradable and toxic nature. Natural anthropogenic sources of Hg adversely affect the functioning aquatic ecosystems biological processes. In sub-Saharan Africa (SSA), unregulated artisanal small-scale gold mining (ASGM) contributes up 20% production uses 205–496 tonnes/yr Hg. Despite being a vital economic driver for 20–30 million people, ASGM threatens health systems from pollution, presenting complex challenge...
Summary Positive biodiversity–ecosystem function relationships (BEFRs) have been widely documented, but it is unclear if BEFRs should be expected in disturbance‐driven systems. Disturbance may limit competition and niche differentiation, which are frequently posited to underlie BEFRs. We provide the first exploration of relationship between tree species diversity biomass, one measure ecosystem function, across southern African woodlands savannas, an ecological system rife with disturbance...
Abstract Background and Aims Little is known about the response of ground layer plant communities to fire in Miombo ecosystems, which a global blind spot ecological understanding. We aimed: (1) assess impact three experimentally imposed treatments on species composition compare it with patterns observed for trees; (2) analyse effect richness how responses differ among functional groups. Methods At 60-year-long experiment Zambia, we quantified diversity plants terms taxa groups across...
Africa is entering a new fire paradigm, with climate change and increasing anthropogenic pressure shifting the patterns of frequency severity. Thus, it crucial to use available information technologies understand vegetation dynamics during post-fire recovery processes. The main objective this study was evaluate seasonal spatio-temporal trends in response fires across Africa, from 2001 2020. Non-parametric tests were used analyze MODIS Normalized Difference Vegetation Index (NDVI) products...
ABSTRACT Anthropogenically accelerated metal pollution of lotic systems draining mining landscapes remains a global concern due to its non‐degradability and ecotoxic nature. Nevertheless, the efficacy macrophytes as indicators remediators metal(loid) pollutants in aquatic ecosystems regions is recognised globally. However, mineral‐rich Central African Copperbelt (CACB), there limited research on effectiveness for management. Therefore, this study investigated phytopotential Typha domingensis...
Abstract There is new and increasing emphasis on the contribution of non-timber forest products (NTFPs) to improving livelihoods rural communities therefore need for sustainable management ecosystems Miombo woodlands ensure continued availability these NTFPs. This paper examines reviews some work that has been done in ecoregion ecology, utilisation woodlands. The review points richness regions' plant species, with an estimated 8 500 species higher plants, which over 54% are endemic. also...
Forests are important ecosystems offering extensive material and immaterial benefits to people the environment. If not well monitored sustainably managed, forest resource use can lead degradation, which has global environmental socio-economic implications. There is currently limited information on factors that in
The miombo woodland is one of the most extensive woodlands in Africa, supporting livelihoods based on biomass fuel for millions rural people. However, there are growing concerns about sustainability harvesting (mainly charcoal). Thus, aim this study was to examine whether regeneration by coppice a viable option sustainably managing production. We tested hypotheses that (1) species, stump diameter, height and time since cutting significantly affect number sprouts per cut (coppice density)...
Globally, belowground biomass (BGB) accounts for 20–26% of total biomass, and as such it is an important carbon (C) pool many vegetation types. However, large uncertainty exists C compared to aboveground stocks. Using data from 108 destructively harvested trees belonging 36 miombo species, we estimated root shoot ratios, developed models estimation (AGB), BGB stocks in the Copperbelt province Zambia. We also validated our using independent datasets elsewhere Zambia Malawi. The fractions wood...
