Paraquat Fact Sheet. Paraquat is a herbicide (chemical weed killer) used to control a very broad range of weeds (unwanted plants) in more than 100 crops, including cereals, oilseeds, fruit and vegetables, growing in all climates. Weeds shade crops, take their water and nutrients, and make harvesting difficult.araquat Fact Sheet.

1.1 DEFINING COASTAL AREAS. Coastal areas are commonly defined as the interface or transition areas between land and sea, including large inland lakes. Coastal areas are diverse in function and form, dynamic and do not lend themselves well to definition by strict spatial boundaries.he multifaceted approach to the management of coastal resources has become known as integrated coastal management (ICM). Pernetta and Elder (1993) have described it as meaning `the process of combining all aspects of the human, physical and biological aspects of the coastal zone within a single management framework'.
Other coastal categories: 1  A cliffed coast or abrasion coast is one where marine action has produced steep declivities known as cliffs. 2  A flat coast is one where the land gradually descends into the sea. 3  A graded shoreline is one where wind and water action has produced a flat and straight coastline.ugged coastline of the West Coast Region of New Zealand. A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. A precise line that can be called a coastline cannot be determined due to the Coastline paradox.
