Desertification Natural Background and Human Mismanagement【電子書籍】[ Monique Mainguet ]

＜p＞After UNCED (United Conference on Environment and Development, Rio de Janeiro, July 1992), a second edition of ＜strong＞Desertification＜/strong＞ was necessary. About 150 corrections, amendments and additions take scientific progress into account. The author also presents an updated chapter in which the results of UNCED are analyzed.＜br /＞ This book aims at an understanding of what is commonly called "desertification" - a term which is proposed to be replaced by "land degradation". Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in an increase in land degradation and eventually a decrease in soil productivity. The benefit to the reader is an awareness of the ecozones and a global overview of the phenomena, mechanisms and existing solutions.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。
