Introduction,nce-thriving civilizations that vanished because of the degradation of the very resource base on which they flourished. Soil erosion prediction technology began over 70 years ago when Austin Zingg published a relationship between soil erosion by water and land slope and length, followed shortly by a

Perspectives of Vegetation Ecology and Biodiversity for Management of Ravine Lands,vocated. The indigenous woody vegetation and perennial grasses are considered generally more effective in halting runoff and erosion than cultivated crops and exotics. The native species have adapted themselves against all edaphic and biotic pressure and have capacity to regenerate along eroded slop

Plant Biodiversity of Ravine Ecosystem: Opening New Vistas for Enhancing Productivity,ation, the forest areas under ravines are facing severe threats of losing biodiversity. Biodiversity of an area determines the health of the ecosystem. The degraded ravine ecosystem also harbors rich diversity and provides fuelwood, fodder, medicines, and small timber to the local dwellers. The biod

Nutrient Management Strategies for Improving Soil Health and Productivity of Ravine Lands, very little organic matter and very poor binding capacity. There are tremendous soil (> 30 Mg ha. year.), water (> 70% of rainfall), and nutrient (> 350 kg of NPK year.) losses during rainy season, and this problem is still aggravating to the farmers by spreading to fertile lands. The loosely held

,Gully Erosion and Land Degradation in Brazil: A Case Study from São Luís Municipality, Maranhão Stais chapter discusses gully erosion and land degradation in Brazil, outlining a case study from São Luis City, Maranhão State. This diversity is related to a wide variety of landforms, climates, parent materials, vegetation cover and biota and is influenced by land use and management. Therefore, a br
