TLDR
With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.Abstract:
Soil erosion is a major environmental threat to the sustainability and productive capacity of agriculture. During the last 40 years, nearly one-third of the world's arable land has been lost by erosion and continues to be lost at a rate of more than 10 million hectares per year. With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.read more

Soil Fertility and Biodiversity in Organic Farming
TL;DR: Results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced.

Understanding relationships among multiple ecosystem services.
TL;DR: A typology of relationships between ecosystem services based on the role of drivers and the interactions between services is proposed to help drive ecological science towards a better understanding of the relationships among multiple ecosystem services.

World Agriculture: Towards 2015/2030: An Fao Perspective
TL;DR: The FAO's latest assessment of the long-term outlook for the world's food supplies, nutrition and agriculture is presented in this paper, where the projections cover supply and demand for the major agricultural commodities and sectors, including fisheries and forestry.
Journal ArticleDOI
Soil erosion and agricultural sustainability
TL;DR: Data drawn from a global compilation of studies quantitatively confirm the long-articulated contention that erosion rates from conventionally plowed agricultural fields average 1–2 orders of magnitude greater than rates of soil production, erosion under native vegetation, and long-term geological erosion.

Soil Erosion and Conservation
TL;DR: In this article, a review of worldwide land degradation problems is presented, focusing on delineating and estimating the magnitude of soil erosion, quantifying erosion and sedimentation impacts on land productivity, establishing quantitative values for erosion-causing parameters, and implementing global and regional soil and water conservation programs.
