Management of wildlife species has recently become a global concern as most are threatened to near extinction or endangered. The establishment of national parks such as the Sapo National Park (SNP) in the 1980s as a conservation area has been found as one of many solutions for protection of wildlife species in Liberia. Nonetheless, due to various natural and anthropogenic drivers and pressures, the SNP is under consistent threat of losing its biodiversity integrity. Various factors including wea...

This research aims to highlight the effect of human activities and speculative fishing on the dynamic of Tiko mangrove landscapes. The study is based on the collection of bibliographical and factual data (field observations, botanical records) and the diachronic analysis of satellite images of the locality over the past five decades. The NDVI method was used to illustrate the dynamics of land use between 1976, 1986, 1996, 2006 and 2016. Botanical surveys were carried out in three transects 100 m...

Fire is commonly used to remove long, dry, low-nutritious grass and generate fresh grass for wildlife. The study sought to examine the impact of prescribed burning on common herbivore abundance and habitat selection in Matekenya Vlei, Sengwa Wildlife Research Area (SWRA). Four-line transects, two in each block (burnt and unburnt) were set. The average length of each transect was 2.5 km. Daytime transect surveys were conducted between 07:00 hours and 08:00 hours morning and 16:00 hours and 17:00 ...

Global climate change has recently received attention as it affects species distribution at all scales. Many species, including invasive species, have indicated a shift in their ecological ranges in response to climate change. However, little is known about the impacts of climate change on house crows ( Corvus splendens) habitat distribution in Tanzania. We assessed the impacts of climate change on current and future potential suitable habitat distribution for house crows using Maxent 3.4....

For several decades, many households in rural areas have relied on surrounding forests for their livelihoods, safety nets and sustenance. This reliance is most often determined by the household’s characteristics, available forests and economic benefits. That notwithstanding, the demand for more farmlands and unsustainable harvesting of forest resources are pushing these forests into depletion. This rapid decline endangers the livelihoods of forest-reliant households, threatens biodiversity and i...

In Uganda, sorghum constitutes the second most widely grown cereal according to the latest statistics from the country’s statistics body, the Uganda Bureau of Statistics. This notwithstanding, there has been, in the context of Uganda, very little research and published literature on its potential to sequester carbon. There is no sufficient data on the exact levels of carbon sequestered by this sorghum/legume intercropping system, which is widespread as a technology within Uganda’s smallholder so...

Anthropogenic activities along Okpare creek are mainly farming, irrigation, fishing, domestic activities, lumbering and sand mining and these activities can alter some natural components of the creek, hence this study aimed to assess the impact of anthropogenic activities on the surface sediment quality of Okpare Creek in Niger Delta. The sediment samples were collected and analyzed for physiochemical parameters as well as heavy metal content. Sediment quality parameters examined were pH, electr...

In many geographic areas influenced by tropical and temperate climates, natural forest ecosystems have been destroyed in favour of plantations of allochthonous trees which are economically profitable for different aspects of the timber industry. Some of these mature plantations degrade the soils and inhibit natural regeneration of the local flora; others, due to the physical constraints they impose, can contribute to the installation and the development of autochthonous taxa. The plantations of ...

The preservation of suburban agricultural land in the face of rapid urbanization in the West African region has been a major problem in recent decades. This paper examines the land tenure strategies used by farmers in relation to their assessments of the impact of urban growth. It is based on individual surveys conducted among farmers and landowners on the outskirts of the city of Lomé in Togo. This study reveals that perceptions differ according to gender and that women—although marginalized by...

The purpose of this research is to assess the evolution of the mangrove swamp near Douala international airport over the past five decades. The study is based on the collection and processing of data (bibliographic, aerial photographs respectively from 1974, 2003 and 2009; Landsat Multispectral scanner satellite images from 1974, Quickbird from 2003 and Geo Eye from 2012 and 2020). The study is also based on observations and surveys (with 37 semi-interviews, 03 focus groups and the administratio...
