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'.
Coastal Features. Wave action leads to the formation of many features along the coast. Some of these coastal features are formed as a result of erosion by waves whereas others are formed by the deposition of material along the coast by waves.Let us examine these coastal features in turn.ongshore drift is the process by which material is moved along the beach by wave action. This process is responsible for forming coastal features such as spits and tombolos. The video below explains the process of longshore drift.
