Managing denitrification in human-dominated landscapes

Ecological Engineering, November 2010.

This special issue of Ecological Engineering presents products from the Denitrification-RCN workshop held at the Coastal Institute of the University of Rhode Island, May 2009. This workshop brought together over 40 ecologists, engineers, and policy experts to combine their collective, inter-disciplinary expertise to address a common goal of using ecological principals in engineering designs to help control nitrogen pollution.

New approaches to modeling denitrification

Biogeochemistry, March 2009.

This special issue of Biogeochemistry presents products from the first workshop in the Denitrification RCN series which had modeling denitrification as its primary focus (November of 2006). The current status as well as new advances in modeling denitrification in terrestrial, freshwater and marine environments are covered, with an overall emphasis on scaling up from small scales to whole watershed perspectives.

NSF's Denitrification Research Coordination Network (RCN)

This project began in 2005 with the overall objective of creating a community of denitrification scientists from a wide array of disciplines, from molecular biology to ecosystem science, and from soil science to oceanography. Despite many denitrification studies, only a few locations have measurements adequate to quantify rates or to understand factors controlling denitrification at the ecosystem scale. The focus of activities of the Denitrification RCN is to advance across the range of terrestrial and aquatic ecosystems on earth: 1) quantification of denitrification rates, 2) development of quantitative, process-based relationships between rates of denitrification and controlling factors, and 3) production of spatially explicit, process-based models that can be used to scale-up site specific measurements to ecosystem, regional and global scales.

While the Denitrification RCN has just been established, our long-term (10-15 year) vision is to have spatially explicit maps of denitrification rates for the entire earth system under current conditions, as well as past and hypothetical (future) scenarios. Toward that objective the RCN will:

  • Facilitate the sharing of recent methodological advances in denitrification measurement and models
  • Stimulate additional methodological improvements
  • Enhance coordination of research activities and facilitate new joint research programs in under-sampled ecosystems and geographical regions
  • Promote synthesis and integration at various scales
  • Catalyze and stimulate interaction of scientists with policy-makers and managers on denitrification issues of concern to society
