Overview

James A. Harris is affiliated with Cranfield University in the United Kingdom. Their research primarily spans the fields of Environmental Science and Agricultural and Biological Sciences, with a substantial focus on specialized subfields including Global and Planetary Change, Plant Science, Ecology, Health, Toxicology and Mutagenesis, and Soil Science.

The scientist's work extensively covers topics such as Land Use and Ecosystem Services, Urban Green Space and Health, Soil Carbon and Nitrogen Dynamics, Microbial Community Ecology and Physiology, Ecosystem Dynamics and Resilience, Legume Nitrogen Fixing Symbiosis, and Ecology and Vegetation Dynamics Studies.

Frequent co-authors in their collaborative research include Ron Corstanje, Mark Pawlett, Joanna Zawadzka, Tom Sizmur, and Ian M. Clark. This highlights a network of partnerships contributing to interdisciplinary research outputs.

James A. Harris has published multiple articles in various academic venues. The most frequent publication venues are:

  • Landscape Ecology
  • SSRN Electronic Journal
  • Applied Soil Ecology
  • European Journal of Soil Science
  • Ecological Engineering

Selected recent papers exemplify the themes and the scope of their research:

  • "Bundling ecosystem services at a high resolution in the UK: trade-offs and synergies in urban landscapes," 2021, Landscape Ecology
  • "Future restoration should enhance ecological complexity and emergent properties at multiple scales," 2021, Ecography
  • "Assessment of heat mitigation capacity of urban greenspaces with the use of InVEST urban cooling model, verified with day-time land surface temperature data," 2021, Landscape and Urban Planning
  • "Understanding the importance of landscape configuration on ecosystem service bundles at a high resolution in urban landscapes in the UK," 2021, Landscape Ecology
  • "The impact of anaerobic digestate on soil life: A review," 2023, Applied Soil Ecology

Their publications reveal an engagement with both landscape-scale environmental dynamics and soil ecological processes, frequently addressing how ecosystem services can be optimized and measured, especially in urban or managed landscapes.

This research profile demonstrates a consistent interest in the interactions between land use, ecosystem functions, and sustainability, particularly through empirical approaches and model-based validation methods.
