The status of waste and its impact on macroinvertebrate assemblages along Msimbazi River was assessed between May 2014 and August 2014. The aim was to identify the type of waste, their potential sources, and the assemblage of macroinvertebrate taxa that have been affected by waste disposal in the river. The study involved field study and laboratory...

Flowers of the seagrass Halophila stipulacea (Forsskål) Ascherson in Tanzania are currently unreported. The present study was conducted along the coast of Tanzania, Indo-Pacific, Kunduchi intertidal mudflats. Transplanted cuttings from Kunduchi intertidal mudflats were successfully grown in sand-mud substrate in the growth chamber in a 12 h photope...

Coastal erosion is a serious environmental problem that has caused the loss of private infrastructure and national assets along Ghana’s coast. Several hard engineering measures have thus been used to protect some communities and vital state assets when they became threatened. Regardless of this problem, sediment mining activities are increasingly p...

Nest success of the Indian House Crow Corvus splendens was studied in the urban area of Dar es Salaam, Tanzania, in late March to early May 2011. The study investigated nest success of the Indian House Crow in different tree species with varying canopy covers and heights. Fifty-five active nests and 38 inactive nests were observed and inspected fro...

The suitability of using macroinvertebrates as bioindicators of stream water quality was tested in the Mkondoa River in an agricultural area at Kilosa, using the rapid bioassessment protocol. The family biotic index (FBI) showed marked variation in water quality along the stream from values ranging from 4.1 to 5.0 in the upstream reaches, indicatin...

Even though global interest in mangrove research has increased in recent years, unveiling their immense ecological and economic roles, very little work has been done to investigate the primary driving factors motivating long-term community-based mangrove restoration and management on local scales. In Ghana, policy makers and coastal management prac...

Follow this link http://rdcu.be/nkkX to read full paper Mangrove wetlands are one of the most important ecosystems on earth, providing habitats for both marine and terrestrial organisms as well as supporting essential human services. However, high dependence of humans on these systems is leading to significant transformation of mangrove wetlands a...

Most coastlines in the world are under the threat of erosion. As such many developed nations have instituted long-term measures to control the rate of change. However, along most developing nation coastlines, little attention is given to coastal erosion management. Ghana like most developing countries has little commitment to ensure the effective m...

Coastal erosion is a serious problem that affects the safety and livelihoods of many coastal dwellers along Ghana's coast. Despite the fact that coastal erosion is a natural phenomenon, erosion trends have been largely aggravated by human-induced factors. This study analyzed shoreline change rates for three neighbouring coastal communities in the C...

In sub-Sahara African nations like Ghana, Sarotherodon melanotheron is steadily gaining attention as an alternative to the popularly over-burdened cultured cichlid species Oreochromis niloticus for animal protein. We investigated the relation between gill length and gill volume as well as the relation between some morphometric parameters of the S....

Main speaker at ’Save Our Beaches’ National Forum on protecting Ghana’s beaches, held at the National Theatre of Ghana on the 12th of November 2015.

The increasing urbanization of much of the world’s coasts threatens irreversible damages to beach ecosystems, if unchecked. Unfortunately, beach monitoring programmes for remediation actions are uncommon, especially for less developed nationswhere infrastructural development and socio-economic goals are regarded more important than environmental go...

Like most coastlines the world over, Ghana's coast has been receding, requiring management interventions to protect coastal communities and assets of national importance. In order to adopt sound management interventions that would have a long lasting positive impact on the coastal zone, an understanding of the historic pattern of coastline change a...

Mining of sand and stone from the coasts provides an inexpensive source of materials for the construction industry while providing income to contractors. However, these activities come at a cost to the coastal environment and pose a threat to the tourism industry along the Ghanaian coast. This paper identified the various types of coastal sand and s...

Abstract Human impact has increased stunningly the last century with coastal problems being one manifestation of environmental injustice with ecological, economic, and social dimensions on coastal resources. The study sought to assess the residents’ perception of coastline changes in the milieu of the rampant sand mining activities along the Elmin...
