Coral reef biology
  • The building blocks of coral reefs are the
    generations of reef-building corals, and other
    organisms that are composed of calcium carbonate
  • As coral sheds parts, gets eaten by fish, or
    simply just dies, the calcium carbonate builds up
    in layers
  • This literally builds a reef- an ecosystem of
    live organisms under warm waters

Where Coral reef can be found-
Kenya has many miles of Coral reef which attracts
holiday makers
Coral reefs are estimated to cover 284,300 square
kilometres, with the Indo-Pacific region
(including the Red Sea, Indian Ocean, Southeast
Asia and the Pacific) accounting for 91.9 percent
of the total

Coral reef in Kenya
  • About 70 of the coastal population in Kenya
    depends on fisheries and tourism for their
    livelihood
  • With increasing poverty and mouths to feed,
    fishing continues in the coral reef of Kenya
  • Traditional fishing methods are being replaced by
    use of destructive methods
  • This is destroying the coral, and reducing fish
    numbers
  • This means that even before tourists get to
    Kenya, they are already harming the coral reef
    ecosystem

Tourists pay for guided snorkelling tours of the

Positive impacts of tourism
  • The Indian Ocean coast offers fabulous beaches, a
    tropical climate, and some of the best scuba
    diving in the world. This attracts a lot of
    tourists
  • Tourism has generated jobs in scuba diving-
    offering lessons, guided tours and mini-trips out
    to the coral.
  • There has been an improvement in roads to and
    from the coastal resorts which also helps the
    local fishing industry.
  • Profits from tourism may be invested in education
    and other programmes for local communities.
  • Identification of coral reef areas means that
    conservation can take place- managing the coral
    so that it remains in place

11
Negative impacts of tourism
  • The huge numbers of visitors are damaging the
    coral reefs. Boats and divers themselves can
    damage the fragile coral very easily
  • The scuba diving teachers, and guides earn a
    relatively small wage considering the work they
    do, and how much people pay for their holidays.
  • A large percentage of the money earned by
    tourists paying to scuba dive in the Indian ocean
    goes back to the tour operators and large hotel
    chains, which are based in countries like the
    United States and Great Britain.
  • The massive tourist developments on the Indian
    Ocean coastline have caused an increase in house
    prices in the area, meaning that the locals are
    priced out of the market.
  • The tourists are only adding to the damage to the
    coral being caused by local fishers
