Yield gap analysis—Rationale, methods and applications—Introduction to the Special Issue
Yield gap analysis is an increasingly popular concept. It is a powerful method to reveal and understand the biophysical opportunities to meet the projected increase in demand for agricultural products towards 2050, and to support decision making on research, policies, development and investment that is needed. This Special Issue presents the state-of-the-art about concepts, methods and applications of yield gap analysis. The methodological papers emphasize the need for agronomically sound and relevant analyses, from local to global scales. The fourteen papers provide examples of applications to different crops, climate zones and production conditions, at various spatial extents and with different approaches and data availability. The overall goal of this Special Issue is to provide the scientific foundation for improvement and interpretation of yield gap analyses
New Approaches to Support Development of Sustainable Land Use Systems
In this paper, the land use planning cycle is introduced and some recent efforts at developing appropriate methodologies for supporting some of its distinct phases are illustrated. The examples still largely bear an academic character, but since there is increasing demand by policy makers for integrated land use analysis studies, they may serve as building blocks for development of operational methodologies for land use policy ormulation and analysis. Their potential impacts on planning procedures and chievement of land use objectives are high, particularly when they are further developed and operationalized in settings that allow participation and involvement of the various user group
