2 Conducting and Communicating Environmental Impacts of Research: Forage Production, Soil Health, Sustainability

Abstract

Abstract Sustainability research is complex and involves the evaluation of tradeoffs. Environmental, economic, and social aspects should ideally be considered. Even when one only pillar of sustainability is evaluated, results should be assessed within the broader context of overall sustainability. Environmental impacts from forage and livestock systems, as well as confined animal feeding operations, can be positive and negative, depending on the type of operation, environmental setting, weather episodes, and management conditions. These systems also have associated social and economic impacts. As in all agricultural management systems, there are likely to be hotspots of damage due to a particular management style combined with the right soil, landscape, and climatic conditions. Widespread, positive benefits of pasture-based management are possible when forage resources are utilized ideally with best grazing management principles leading to enhanced soil organic carbon storage, high water infiltration, efficient nutrient cycling, and minimal water and nutrient runoff into nearby water bodies. Research to quantify the environmental impacts of livestock management systems can be designed in detail on research stations to understand the direct implications of management differences on plant biomass production that captures atmospheric CO2, on carbon stored in soil organic matter, and on greenhouse gas emissions from ruminant livestock fed controlled diets. On-farm research is also valuable to characterize the impacts of a particular style of management across a diversity of environments using a system-level approach integrated across the farm. Communication strategies engaging major stakeholders from the livestock industry are key to deliver a consistent message to the general public. Perceived benefits, challenges, and opportunities must be science based, seeking opportunities to reduce negative impacts, and enhancing the positive ones. Messaging to the lay audience about environmental impacts can be focused on solutions from positive benefits or problems from negative effects, but should also address economic and social components.
