Environmental issues and socio-economic problems emanating from salt mining in Kenya: a case study of Magarini District

Hausner Wendo

2013

Salt mining generates colossal profits for the investors and towards Kenya’s revenue margin. However, salt farming in Magarini District has increasingly elicited social concerns locally and ecological stress at large. Subsequently, this paper presents the findings of a study that explored the socio-economic and environmental issues associated with salt farming. Primary data sourced from the local community provided bulk of the information. Through multi-stage cluster and snowball sampling techniques, a sample of 120 households and 12 institutions were identified after which appropriately designed questionnaires were administered. This was augmented by interviews and focus group discussions with key informants and observations. The results documents myriad of issues including: perceived forced evictions, delineations, pollution, health hazards, unacceptable labor conditions, intimidations and corrupt local leadership, among others. This informs the need to develop effective monitorin...

Effects of Salt Harvesting on Ground Water Quality in Gongoni Ward, Kilifi County, Kenya

Ali Gakweli

Asian Journal of Environment & Ecology, 2021

Aims: To determine the effects of salt harvesting on ground water quality in Gongoni ward, Kilifi County. Study Design: The study design was purposive where sampling points were deliberately chosen. Place and Duration of Study: The study was carried out in Gongoni ward and its environs in Kilifi County from May 2015 to July 2015. Methodology: Sixteen sampling points were selected within the study area and sampling was done twice between May and July 2015. The water samples collected were analyzed for sodium (Na+), Chlorides (Cl-), Fluorides, (F-) Calcium (Ca2+), alkalinity, acidity (pH), E. coli, Total Dissolved Solids (TDS) and Salinity as NaCl in the Government Chemist laboratories in Mombasa. The collected data was analyzed using SPSS and Microsoft Office Excel. Results: The ground water sources in Gongoni ward registered high levels of key parameters (TDS, Salinity, Chloride, and Sodium) than the adjacent areas of Mambrui, Ngomeni and selected secondary data from Mombasa County ...

Perceptions about trends and threats regarding sea turtles in Kenya

Gladys Okemwa

Information on perception, trends, status and major conservation issues relating to sea turtles in Kenya was collected between November 2003 and December 2004 among 23 communities along the 600 km long Kenyan coast. The objective was to determine major conservation issues and identify solutions. The survey employed participatory rural appraisal (PRA) methods including transect walks, observation, resource mapping, problem visualizations, seasonal calendars, time lines, resource prevalence trend lines and structured interviews. Data was analysed through ranking and scoring. Respondents indicated a steady decline of 25-75% of the sea turtle populations in six sites since the early ‘80s. Overall, marine fisheries were identified as a leading cause of marine turtle strandings on Kenyan beaches accounting for over 50% of reported cases. Over 90% of the participants indicated willingness to conserve sea turtles by using appropriate fishing gear but cited lack of capital outlay to purchase...

Seasonal fluctuations in zooxanthellae densities in corals in the Mombasa Marine Park, 1998-2006

David Obura

2009

Tropical reef-building corals contain micro-algae known as zooxanthellae within their tissue with which they exist in an obligate symbiosis (Muscatine & Porter 1977). Zooxanthellae are crucial to coral polyps because they provide them with photosynthates, energy, oxygen and pigmentation. They in turn receive carbon dioxide, nutrients, protection and access to light (Muscatine 1973; Trench 1979). This symbiosis underpins the existence of coral reefs.

The capacity of fisherfolk to implement beach management units in Diani-Chale

David Obura

The Kenyan coastline stretching from the Somali border in the north to the Tanzanian border in the south, covering an approximate distance of about 600 km, is endowed with high marine biodiversity. The area is rich in marine resources that include coral reefs, fisheries, mangrove forests and seagrass among others. It also has sandy beaches that attract tourism related activities. Many communities along the coastline depend on the marine and coastal environment and its associated resources for livelihood.

Geomorphic and Climatic Drivers Are Key Determinants of Structural Variability of Mangrove Forests along the Kenyan Coast

Derrick Muthomi Njiru

Forests

Mangrove forests occur across a diversity of coastal landforms that influence their structural development and productivity. Preliminary studies in Kenya indicate that mangroves growing in the region north and south of Tana River delta have different structural attributes. We hypothesise a close relationship between mangrove distribution, climate and landform types. Floristic composition of mangroves along the coast of Kenya was characterised and differences illustrated using non-metric multidimensional scaling (nMDS). Other structural properties of mangroves such as tree height, basal area, stand density and standing biomass were also assessed and their differences tested using analysis of variance (ANOVA). A hierarchical cluster analysis was used to compare mangrove species based on structural properties. Additionally, a regression fit model was used to investigate the relationship between mangrove standing biomass and possible drivers of variability. The study revealed significan...
