Soil erosion is one of the most serious threats to world food production. During the past 40 years, nearly one-third of the world's cropland has been lost to erosion, and this loss is intensifying. Cropland is already in short supply worldwide. This shortage contributes to the fact that more than 2000 million humans are malnourished. More than 99 per cent of all world food comes from the land and less than one per cent from the oceans and other aquatic ecosystems. Therefore, major efforts are needed to conserve soil and protect the environment. Abstract & Keywords → p. 239

More about this publication?
  • GAIA is a peer-reviewed inter- and transdisciplinary journal for scientists and other interested parties concerned with the causes and analyses of environmental and sustainability problems and their solutions.

    Environmental problems cannot be solved by one academic discipline. The complex natures of these problems require cooperation across disciplinary boundaries. Since 1991, GAIA has offered a well-balanced and practice-oriented forum for transdisciplinary research. GAIA offers first-hand information on state of the art environmental research and on current solutions to environmental problems. Well-known editors, advisors, and authors work to ensure the high quality of the contributions found in GAIA and a unique transdisciplinary dialogue – in a comprehensible style.

    GAIA is an ISI-journal, listed in the Science Citation Index Expanded, Social Science Citation Index and in Current Contents/Social and Behavioral Sciences.

    All contributions undergo a double-blind peer review.
