Sacred groves as potential ecotourism sites at Tolon and Diare in Northern Region, Ghana

Purpose: Relic plant communities commonly referred as “sacred groves” in Ghana and comparatively anywhere are ecologically, genetically important resources indigenously protected as “abodes of gods or ancestral habitats” through traditional or religious beliefs and taboos. This study mainly evaluated the potentials of sacred groves for development as tourist sites at Tolon and Diare in the Northern Region of Ghana. Research methodology: Data was collected using semi structured interview questionnaire aided by vegetation survey, observational field walk through the Jaagbo and Tindangung Sacred Groves to screen natural features of the destinations and determine its potential for ecotourism. Findings: Potential areas for visitor amateurism such as the wonderful baobab tree, crocodile pond, misty stone bird sanctuary, were identified in both groves. About 220 different species of plants were identified in the entire groves. The study further discovered that with effective management measures in place, the ecotourism potentials of these sacred groves will optimize if developed to attract visitors and generate income for sustainable socio-economic development of the adjoining communities in northern Ghana. Limitations: Although the target population was above 200 people, relatively small sample size (≤ 36%), could be chosen since the opinion leaders considered the groves as sacred and were less prepared to divulge information about them. Islam and Christianity rather counteracted certain beliefs of the traditional people who adopted local measures to enhance sustainability of these sites for ecotourism functions. Contribution: The study advocates the adoption of bylaws to promote sustainable management of the sacred groves for sustainable benefits.

Characterization of dumpsite waste of different ages in Ghana

Open dumping of municipal solid waste is a common practice in developing countries including Ghana and it creates major problems in many municipalities and towns in the countries, and therefore, the dumpsites need to be reclaimed or decommissioned after years of dumping. However, it becomes challenging to infer from the results of studies from other part of the world for dumpsites in Ghana since they may have different waste characteristics. Therefore, this study sought to characterize the dumpsite waste with different age groups from urban city and small town to ascertain the impacts of aging of deposited waste on waste fractions, it also assessed the waste components at different depths within the same and different age groups in both small-town and urban dumpsites; for waste deposited more than 5 years (Zone A), 2–4 years (Zone B), and less than 6 months (Zone C) in Bono region, Ghana. Waste (100 kg) was taken at surface, 0.5 m, 1.0 m and 1.5 m and reduced to 50 kg using coning and quartering method; dried, segregated and analyzed. Plastics waste (24.5–28.1%) increased with age at urban, and increased (5.4–8.5%) with depth at small town dumpsite. Plastic waste was second to Decomposed organic matter (DOM) at both dumpsites. The metal (<1.0%) at all depths in all age groups for both sites. DOM fine particle sizes (FPS) decreased with depth, 26.8% (surface waste) and 14.4% (1.5 m depth), at both dumpsites. Statistically significant effects of age on plastics, metal, DOM-CPS, DOM-FPS (p < 0.05) at urban dumpsite. However, at small town dumpsite, effect of age was statistically significant on only DOM-CPS and DOM-FPS (p < 0.05). The pH, EC, and TDS for both dumpsites decreased with increasing age, and increased with depth. The study provides relevant scientific findings for stakeholders to develop policy framework for dumpsite decommissioning or reclamation

Physicochemical properties and heavy metals distribution of waste fine particles and soil around urban and peri-urban dumpsites

In developing countries like Ghana, the use of open dumpsites and landfills without proper waste management technique has resulted in environmental pollution with long-term adverse effects on soil, groundwater, human health and environmental sustainability. This study assessed the contaminants in fine particles of dumpsite waste and soil around urban and peri‑urban dumpsites at different depths of excavation and different age of deposited waste. Specifically, the study: (i) assessed physiochemical properties of fine particles of dumpsite waste and the surrounding soil, (ii) assessed heavy metals distribution from waste fine particles and surrounding soil at different depths and different ages of deposition, (iii) also determined soil quality indices (pollution index, geo-accumulation, and the potential ecological risk), and the hazards associated with the dumpsites on the residents living near the dumpsites. About 50 kg of waste was taken from surface, 0.5, 1.0 and 1.5 m depths. The samples were dried, segregated and sieved to obtain fine particles. Again, 1 kg soil was excavated form 0.5, 1.0 and 1.5 m depths at different age zones around each dumpsite. The fine particles and soil were analysed for physiochemical parameters using standard methods, and heavy metals using microwave plasma spectroscopy. The results showed that, the concentrations (electrical conductivity, potassium, cadmium, iron, copper and zinc) of waste fine particles and soil samples observed statistically significant different between them (p  6). High potential ecological risk of Hg (RI = 514.29), and (RI = 571.43) was observed at (SMZC1) and (NZA1) respectively; and high potential ecological risk of Cd (1000 ≤ RI ≤ 320), at (SMZA1-SMCA4. The study shows that both dumpsites have caused environmental hazards and this can cause surface and groundwater pollution and adverse effect on public health. But the study could not assess the impacts of dumpsite on leachate and water quality. The findings can be used as benchmark for developing appropriate technology for dumpsite mining, reclamation or decommission project; and exploit valorization potentials of the fine particles of the waste as composite and construction materials
