This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.

This book focuses on drylands such as arid, semi-arid and dry sub-humid areas where they form the main part of ecosystems, e.g., in Iran, but also around the world. Mismanagement and improper exploitation of these areas lead to more degradation day by day. Besides an introduction to the role and importance of vegetation cover in conserving soil against wind and water erosion, this book gives a scope of appropriate techniques and methods for vegetation establishment and maintenance, indicators for suitable plants selection for soil conservation, and soil erosion prevention and combat. It provides methods of soil erosion prevention and combating through the application of plants, using bioengineering systems for soil erosion control and the role of agroforestry in soil erosion prevention. This book can be helpful to those with an interest in countries with similar climates to Iran. In particular, this includes Dubai, Kuwait, Saudi Arabia, Afghanistan, and Pakistan.

Good punctuation is crucial for successful academic writing. Many students' essays use little punctuation beyond commas and full stops. But to be restricted to just two forms of punctuation mark, when writing your essay, is like building a house using only a hammer and a saw: you can do it;but not very well.By learning to use more, or all, of the available forms of punctuation you will be able to communicate and express your ideas, and arguments, more clearly.
