Sustainable economic and ecological grazing systems - learning from innovative practitioners

点击翻译按钮获取中文摘要

Grassland systems dominating the agricultural landscape in GB are largely economically unproductive, ecologically degraded, dominated by a single grass species, organic carbon poor and heavily reliant on inputs to maintain productivity. System impacts are often felt beyond field boundaries with slurry and P and N pollution from intensive practices leaking into water bodies and impacting on nutrient status and species diversity. Changing to sustainable systems through innovation can rely on cues from the natural environment. Naturally productive systems which support large numbers of grazing livestock have provided inspiration for Pasture for Life (PfL) certified producers to adopt pasture management practices which mimic those systems. Methods include approaches such as 'herbal leys and diverse swards' and 'mob grazing' which can potentially extend the grazing season whilst providing environmental, economic and livestock benefits in terms of health and productivity. The proposed research aims to evaluate the ecological, agronomic and social impacts of the pasture fed livestock approach to grazing management and its potential as the basis of a sustainable GB-wide system. To achieve this, an experienced interdisciplinary research team has designed a project that will deliver a formal assessment of the agronomic, socio-ecological and sustainability and resilience aspects of Pasture Fed Livestock Association (PFLA) members farm systems and the social systems in which they are embedded (including industry bodies and citizen-consumers) through a combined set of social and natural science research methodologies. The team will work closely with producers and their supporting organisations (including the PFLA) to assess sustainability criteria covering a broad spectrum of sixty PLFA enterprises and to assess specific management practices, like 'mob grazing' on a smaller number of (15-20) Pasture for Life (PfL) certified enterprises. The work will seek to identify the motivations, knowledges and ways of learning of the agricultural innovators employing these approaches. It will also investigate the role of governance structures surrounding farms as well as considering their agronomic and ecological impacts. The evaluation will include an assessment of PFLA enterprises within the context of current grassland/grazing management practices. It will investigate the broad range of public goods delivered by PFLA farms - from the animal products themselves to the impacts of the farming practices on aesthetic values and carbon sequestration. The results of the project will provide much needed evidence about the benefits of pasture fed livestock approaches for those farming grazing livestock, consumers of PfL products and wider publics. Such evidence will be valuable for livestock producers (including those already engaged in the practices) and for government and farming bodies, like the Agriculture and Horticulture Development Board (AHDB) with the power to influence farmer decision making. The research will identify key factors which influence 'agricultural innovators' to take bold steps towards novel management practices and provide information on possible mechanisms for supporting them in their enterprises. If such systems do prove to provide significant ecological, agronomic and social benefits the project may help to transform some of the green deserts which currently form much of the agricultural land area in GB. The prospect of a resilient, agriculturally productive, grassland landscape which is storing carbon, preserving water quality and enhancing biodiversity is a compelling one for farmers, governments and wider publics.
