A report to the African Union Commission (AUC) at the United Nations Climate Change Conference in Copenhagen (7-18 December 2009). “In Gambia ... In 1998, the high water mark (HWM) was 50 m from the new Banjul-Serekunda Highway; in 2003 the HWM was only about 15 m from the highway” (Adaptation to Coastal Climate Change Project, ACCC, 2006a). Between Cape Point and the Banjul dockyard and the area between the Palm Grove Hotel and the Muslim cemetery erosion rates of between 15 and 20 m were recorded from 1964 to 1982...”
In one brief paragraph we see the relentless attacks of rising sea levels and growing storm surges on one coastline, threatening four significant elements of society – transport, trade, tourism and tradition.
2009-01-01T00:00:00ZKenSea – tsunami damage modelling for coastal areas of KenyaTychsen, J.Geertz-Hansen, OleSchjøth, Frandshttp://hdl.handle.net/1834/92012021-05-19T06:16:25Z2008-01-01T00:00:00ZKenSea – tsunami damage modelling for coastal areas of Kenya
Tychsen, J.; Geertz-Hansen, Ole; Schjøth, Frands
The tsunami modelling is based on the assumption that the
height of a future tsunami wave would be comparable with the
one that reached the coastal area of Kenya in December 2004.
Based on the regional geology of the Indian Ocean, it appears
that the epicentre for a possible future earthquake that could
lead to a new tsunami would most likely be situated in the eastern
part of the ocean. Furthermore, based on a seismological
assessment it has been estimated that the largest tsunami that
can be expected to reach eastern Africa would have a 50%
larger amplitude than the 2004 tsunami.

The National Tuna Management and Development strategy
provides a roadmap for the sustainable development of the Kenya's
tuna fisheries resources occurring in the Exclusive Economic
Zone (EEZ) and ensuring an efficient tuna fisheries value
chain. The overall goal of the strategy is to transit tuna fisheries
from artisanal-based fisheries to modern commercially oriented
coastal and oceanic fisheries and accelerate economic growth
of the marine fisheries with direct positive impacts to employment,
wealth creation, improved incomes and foreign exchange
earnings.
Chapter two reviews the current situation of tuna fisheries from
a global, regional and national perspective regarding the status
of tuna stocks, exploitation and impacts on marine ecosystems,
the obtaining trade regimes and value chain activities and the
prevailing tuna fisheries governance system. The strategy identifies
four main strategic issues namely; Unsustainable utilization
of marine resources; Low economic benefits accruing from
tuna fisheries to the national economy; Inadequate tuna fisheries
governance and General cross-cutting issues including gender
issues, and HIV and Aids.
To address the strategic issues, four strategic objectives are
prioritized for implementation. First, the maintenance of tuna
stocks at sustainable levels and minimizing negative fishing
impacts on the marine ecosystem. Secondly, transformation of
tuna fisheries from artisanal fisheries to a modern commercially
oriented coastal and oceanic fisheries and developing an effective
tuna fisheries governance system that takes into account
national, regional and international requirements and addressing
the impact of HIV/ AIDS pandemic and gender issues in
tuna fisheries. A detailed implementation matrix for each strategic
objective with the relevant activities is outlined in chapter
five. Mechanisms for measuring progress during implementation
and financing arrangements are highlighted in Chapter six.

Methanol (MeOH) extracts of the pan-tropic marine Cyanophyte Lyngbya majuscula,
Thallassodendron ciliatum (sea grass) and gill extracts of the Striptail damsel Abudefduf sexfasciatus were
examined for in-vitro antiprotozoal activity against Ochromonas danica cultured
in hemin enriched media at room temperature using a 50% serial dilution technique. Respiratory
inhibition at the 660 nm wavelength was shown to be proportional to the concentration of the extracts
with R2 values of 0.992, 0.996 and 0,542 for L. majuscula,Asexfasciatus and T. ciliatum respectively.
T. ciliatum exhibited lower inhibition potential where as Asexfasciatus had the highest.
Malnourished O. danica at the elevated dilutions of 75% were especially susceptible. In addition
to the anticipated antibiosis, rhodamine toxicity and brine shrimp anemia bioassay suggest a
role by haemolysin toxins of L. majuscula and A.sexfasciatus in the 24 hour respiratory inhibition
process.
