Organic and low-input farming practices are considered keystones for the conservation of biodiversity in semi-natural systems. Accordingly, attention to the assessment of the benefits stemming from these activities is increasing in order to provide a solid base for the adoption of agro-environmental incentives and to support their monitoring and evaluation. The evaluation of the positive effects of organic and low-input farming activities on biodiversity is limited mainly by: the difficulty in proposing simple and widely-applicable indicators of biodiversity, and the substantial lack of data concerning the costs of measuring biodiversity - an essential element for a cost-effectiveness analysis. Moreover, the limited scientific literature available is based on ex-post analysis rather than on systematic data collection. The assessment of the costs of measuring biodiversity at farm-scale throughout Europe is one of the specific tasks of the BioBio project (UE-FP7). In this work, we discuss methodological aspects and preliminary results based on data gathered during fieldwork measurements of biodiversity in BioBio.

International audience ; About one-third of the world's land surface is used for farming, a fact that bears important implications for biodiversity. In Europe, for instance, an estimated 50 percent of all wild species are reliant on agricultural habitats, while agricultural productivity often depends on the presence or absence of particular species. Despite this close coupling, surprisingly little is known about the status and evolution of farmland biodiversity. A team of European and African researchers, hoping to fill this gap in information, recently invented and piloted a new toolbox called the BioBio indicator set, which measures 23 different instances of biodiversity across a variety of farm types and scales in Europe. Applications were also tested in Tunisia, Ukraine, and Uganda, where they proved a feasible starting point for adaptation to the agricultural context of different countries.
