The Coastal Zone

1.0 Introduction

The coastal area of Guyana is home to over 90% of the country's population. It has a total area of 16,800km2 , approximately 7% of the total area of Guyana. It has a population of about 700, 500 people, giving the coast a population density of 41.7 people per km2. The coast is the administrative and agricultural centre for the country, and also a significant area for environmental concern.
 

1.1 The geography of the coast

The coast itself is under sea level by about 2 metres. The flat narrow strip along the Atlantic coast was built up from centuries of sediment accumulation from the large South American rivers. This action has given rise to the fluvial soil type, which is mostly clay of varying properties along the coast. Today the processes of accretion and erosion are still very active. While the coast along the ocean is mostly clay, there are sections that are sandy, particularly near the river mouths and along some river banks. Examples can be seen in plates 1- 2. Mud flats off the shore is a common feature along the coast as it travels along the Guiana coast, see plate 3.

1.2 Vegetation and wildlife

Much of the original vegetation of the coast has been removed during the activities of colonizers who cleared and filled the swampy land to make it suitable for cultivation. However, today several species of mangrove still abound as well as hardy wild plants abound, such as those commonly known as Carrion crow Bush, Black and Sweet Sage bushes are just a few, in addition there are various trees that are both indigenous and introduced.

Common wildlife on the coast include birds such as parrots, eagrets, herons, hawks, kiskadees, crows, sparrows, as well as Flamingoes in the wilder regions, mainly Essequibo. Reptiles include sea turtles, alligators, land and water snakes, as well as various species of lizards including the iguana. Numerous species of freshwater and saltwater fish abound, wild mammals such as the mongoose, coney, and monkeys exist in varying numbers.
 

1.3 Urban centres

The two major towns on the coast are Georgetown and New Amsterdam, Georgetown being the capital city is the largest. Its expansion and development has its several implications for the coastal environment such as land use conflicts, mangrove destruction, coastal areas and mangrove stands in some places are now plagued with illegal dumping, particularly old tyres and lumber yard waste.

1.4 Environmental Issues

Concern over the sea defences is always on the local agenda. The diminishing mangrove population along the coast, decreases the natural defences of the coastline against wave action, erosion and flooding. Apart from this mangroves also have ecological benefits for local aquatic life and spin off benefits for local fishery.

There are threats to these mangrove forests however. Local people use them for  leather tanning, as the mangrove trees have the desirable tannins, and to a lesser extent for fuel, but this thankfully is not very widespread.

1.5 Other activities

In addition to being used as an area for agriculture, commerce and industry, the coast also has recreational uses. The seawall that protects it is a popular destination for exercise and leisure, see plate 4. It is also a location of historical value where most of the country's historical artifacts are kept in various museums and archives, also many of the country's remaining colonial structures are also located on the coast.
