Abstract: | Agricultural policy in Europe is changing from supporting production to encouraging environmental benefits in the context of sustainable rural development. As a result, there is a window of opportunity to reconsider the balance between agricultural production and biodiversity management on British farmland, to seek to redress the problems for biodiversity that accrued during intensification without reducing the capacity to meet the coming challenges of global change and population increase. These challenges are discussed in the context of longer term historical change, and in terms of how readily they can be overcome. Current policies can deliver conservation targets that are within the control of individual land managers, and are likely to increase landscape heterogeneity significantly. However, it will be more dif. cult to plan landscapes to deliver agricultural production, ecosystem services and conserve biodiversity in the face of nutrient deposition and climate change. There can be no theoretical “optimum” balance between production and biodiversity, as environmental goals depend greatly upon decisions about scales (from local to global, immediate to long) and the viewpoints of stakeholders. Indeed, the social challenge of delivering sustainable agricultural landscapes is far greater than the scientific one of researching what they might be like. |
