Soils and water [Chapter 18]

Abstract

Bioenergy production can have positive or negative impacts on soil and water. To best understand these impacts, the effects of bioenergy systems on water and soil resources should be assessed as part of an integrated analysis considering environmental, social and economic dimensions. Bioenergy production systems that are strategically integrated in the landscape to address soil and water problems should be promoted where their establishment does not cause other negative impacts that outweigh these benefits (Figure 18.1). While standardized metrics, such as footprints and water- and nutrient-use efficiencies are convenient and intuitive, they can be insufficient to achieving sustainable production and environmental security at relevant spatial and temporal scales. Rather, comprehensive ecosystem impact analysis should be conducted. Sustainability standards and certification schemes should use metrics that are consistent with other agricultural and silvicultural activities and sustainability goals at the local, regional, and global level.
