Sentinel-2 imagery was downloaded from the Copernicus Open Access Hub (https://scihub.copernicus.eu/dhus) using the Multispectral Instrument (MSI) sensor with acquisition dates of 21 February and 09 October 2018, and 18 February 2019 and 04 October 2019. A spatial subset of data was created by given pixel positions using subset operator to crop out...

Background Acacia mellifera like many other bush encroachers in the semi-arid savannas has been blamed by ecologists as it depletes the soil water and underground water because of their high transpiration rate and results in poor understory vegetation. But there are also views that transpiration of bush encroaching species is quite low and there i...

Background: The southern part of Namibia’s terrain is highly inaccessible making it difficult to explore. Expeditions into difficult terrain can result in new biological discoveries for Namibia. Monsonia herrei has been recorded for South Africa, but has not previously been recorded for Namibia. Objectives: As part of updating the biodiversity rec...

Termite mounds by creating patches of increased resource availability (e.g. water and nutrients) are a major source of spatial heterogeneity in savannas. Likewise, mistletoes via input of nutrient-rich litter alter nutrient and water availability increasing environmental heterogeneity in semi-arid savanna. Despite this recognition, the influence of...

KEY LESSONS IN PROGRESSING CBNRM IN POLICY, RESEARCH, AND PRACTICE IN ZIMBABWE The following lessons emerged from a workshop held in Harare in May 2014: a) Emphasis needs to shift from decentralisation towards full devolution beyond the Rural District Councils (RDCs) alongside the increase in capacity of local level institutions (including RDCs) to...

Animals via excretory processes are important in nutrient cycling in agro- ecosystems and can supply nutrients (nitrogen and phosphorus) at rates comparable to major nutrient sources. Land use influenced nutrient levels with mixed areas (wildlife and livestock) indicating the potential of improved nutrient cycling than wildlife and livestock as sta...
