ABSTRACT
Barbados, like most countries of the developing world is caught in the dilemma
of over-utilizing its environment, its coastal zone in particular. In its
quest for development, there is ample evidence of ecological stress,
environmental degradation and inadequate control of land utilization.
One of the problems is the failure to adopt methods and techniques for
systematically monitoring the environment. These problems are concerned
with the conflict between the short term interests of the economy and the
long term interest of the ecology.
This paper is concerned with the application of time sequential aerial
photography to provide environmental documentation of conditions and processes
operating in the coastal zone. To map the type and extent of environmental
use, and to record changes.
The results indicate a trend of environmental degradation. It is clear that
remedial measures are urgently required.
INTRODUCTION.
The purpose of this project of which this report is the first stage, is to
provide environmental documentation of conditions and processes operating in
the coastal zone of Barbados. This information is needed to guide futher
development and to assist in the formulation of methods and techniques to
systematically monitor the environment. The lack of a data base on which to
formulate a rational physical development plan would result in the failure to
reconcile the conflicting demands between the short term interest of the
economy and the long term interest of ecology and preservation.
Barbados is a small (445 kn2), coral-encircled, non-volcanic island, which
lies east of the main chain of the Lesser Antillies, with shores washed both
by the Caribbean Sea and the Atlantic Ocean. Its geographical position is
approximately 139N and 59930'W,100 miles east of St. Vincent, its nearest
neighbour and 300 miles northeast of the South American mainland (Map 1).
About 85 percent of the surface area of this pear shaped island (23 miles in
length and 15 miles in width) is Pleistocene coral rock and associated
sedimentary rocks. The remaining area, consists of older Tertiary sedimentary
rocks (Hunt, 1973).
The geology of Barbados is characterized by two physiographic regions; the
gentle sloping inland terraces which rise from the western coastal region and
the hilly Scotland Series in the northeast, which are dissected by a series of
ravines and ridges trending in a north-eastern direction (Map 2).
The country is naturally endowed with excellent beaches. More than eleven
miles of these beaches are found on the western coast, and the coral formation
