Exploring UAS-lidar as a sampling tool for satellite-based AGB estimations in the Miombo woodland of Zambia.

To date, only a limited number of studies have utilized remote sensing imagery to estimate aboveground biomass (AGB) in the Miombo ecoregion using wall-to-wall medium resolution optical satellite imagery (Sentinel-2 and Landsat), localized airborne light detection and ranging (lidar), or localized unmanned aerial systems (UAS) images. On the one hand, the optical satellite imagery is suitable for wall-to-wall coverage, but the AGB estimates based on such imagery lack precision for local or stand-level sustainable forest management and international reporting mechanisms. On the other hand, the AGB estimates based on airborne lidar and UAS imagery have the precision required for sustainable forest management at a local level and international reporting requirements but lack capacity for wall-to-wall coverage.

Integration of local knowledge in the secondary school chemistry curriculum - A few examples of ethno-chemistry from Zambia.

Before formally introducing chemistry in schools, Africans practiced it as ethnochemistry as they lived in their ethnic groupings. To a large extent, it may be true for other ethnic groups and communities across the globe as well. This study aimed to document a drop from the ocean of ethnochemistry knowledge that people in Zambia practiced in the past and modern times to use such ethnochemistry knowledge to teach chemistry in ethnically responsive ways.

Data to understand the biotransfer of heavy metals along the soil-plant-edible insect-human food chain in Africa.

These datasets consists of concentrations of eight heavy metals (Arsenic, Cadmium, Copper, Chromium, Iron, Nickel, Lead and Zinc) in the soils, in five host plants species, and in seven edible insect species determined using Atomic Absorption Spectrophotometry (AAS). Datasets for the daily intake of metals and target hazard quotients for each edible insect species are also given.

Teacher efforts towards the development of students' mathematical reasoning skills.

Research shows that improved mathematical reasoning results in improved conceptual understanding and the application of mathematical knowledge to a variety of real-world contexts. The assessment of teacher efforts to help students develop their mathematical reasoning, however, and the identification of classroom practices that encourage this growth have received less attention in previous studies. A descriptive survey was conducted with 62 mathematics teachers from six randomly chosen public secondary schools in one district.

Biotransfer of heavy metals along the soil-plant-edible insect-human food chain in Africa.

Although mining is Zambia's major economic activity, it is implicated in environmental contamination, particularly with heavy metals. This study investigated the accumulation and transfer of heavy metals along the soil-plant-edible insect-human food chain. Our results revealed the presence of eight heavy metals (Arsenic, Cadmium, Chromium, Copper, Iron, Nickel, Lead, and Zinc) with a 28-60 % increase in soil concentrations at the proximity of the mining facilities.

The predictors of food security and dietary diversity among internally displaced persons' children (6-59 months) in Bamenda health district, Cameroon.

Background: Malnutrition remains a major cause of morbidity and mortality amongst children in displaced settings. Nutrition at this stage is crucial for the growth and development of the child. It is estimated that 41 million children under 5 years are obese/overweight, 159 million are stunted and 50 million are wasted worldwide.

Use of Multi-Date and Multi-Spectral UAS Imagery to Classify Dominant Tree Species in the Wet Miombo Woodlands of Zambia.

Accurate maps of tree species distributions are necessary for the sustainable management of forests with desired ecological functions. However, image classification methods to produce species distribution maps for supporting sustainable forest management are still lacking in the Miombo woodland ecoregion. This study used multi-date multispectral Unmanned Aerial Systems (UAS) imagery collected at key phenological stages (leaf maturity, transition to senescence, and leaf flushing) to classify five dominant canopy species of the wet Miombo woodlands in the Copperbelt Province of Zambia.
