| Mida Creek (Kenya) comprises mangrove forests and other marine resources that are of economic, ecological and environmental importance to the local village communities. In total 116 households (100 of which could be used for numerical analysis), which are estimated to correspond to a coverage of ca. 30 % of the total Mida Creek population, were interviewed to assess the human reliance on mangrove resources in Mida Creek. The survey indicates that mangroves are a major resource of wood for house construction, fuelwood, charcoal and boat building. Minor uses of mangrove products include pharmaceutical and medicinal applications, tanning material and furniture making. Rhizophora mucronata, Ceriops tagal and Bruguiera gymnorrhiza are the major resources... |

| Historic environmental, faunal, floral and socioeconomic data of Gazi Bay in coastal Kenya were collated and integrated into a GIS environment and data of impacts due to various factors were then related to remotely sensed data. Rhizophora mucronata, a valuable mangrove species, was investigated. Very low values of basal area (7.7 m2/ha and 4.9 m2/ha) and complexity indices (1.86 and 1.12) at Makongeni and Kinondo 1, respectively, reflected intense human pressure in these areas. Areas that were easily accessible or close to human settlements appeared more vulnerable. Accrued information from a socioeconomic survey carried out over the same period corroborates the hypothesis that human influence was a major contributor to these changes. Historic aerial... |

| The structure and regeneration patterns of Mida Creek mangrove vegetation were studied along belt transects at 2 forest sites of Mida Creek (3°20'S, 40°00'E): Uyombo and Kirepwe. Based on the species importance values, the dominant mangrove tree species in Mida were Ceriops tagal (Perr.) C. B. Robinson and Rhizophora mucronata Lamk. Tree density varied from 1197 trees ha–1 at Kirepwe to 1585 trees ha–1 at Uyombo and mean tree height was higher at the former site compared to the latter. The sizeclass structure at both localities of Mida showed the presence of more small trees than large ones. Spatial distribution pattern of adults and juveniles varied greatly between sites and they showed a close to uniform pattern (Morisita’s Index I0 << 1) for... |

| The present PhD dissertation is composed of fourteen papers, preceded by a general introduction and followed by an epilogue that explains the entire research framework, including the links between the different case-studies, the local and global applicability of the results and the relevance of the work in the framework of development co-operation. The bulk of the research was carried out in four sites in Kenya and Sri Lanka: Gazi Bay and Mida Creek in Kenya, and Unawatuna-Galle and Pambala-Chilaw in Sri Lanka. After a revision of the often controversial issue of the floral composition of mangroves in Sri Lanka (SW coast), followed by a synthesis of image attributes in the interpretation of aerial photographs in Kenya and Sri Lanka, a series of... |
