Spatial Recovering of Agricultural Values from Aggregate Information: Sequential Downscaling Methods
In this paper, we propose a downscaling procedure that provides a basis for recovery and estimation of incomplete, aggregate, unknown or indirectly measurable variables. It makes maximum use of information and dependencies on various levels relying o

Global change processes raise new estimation problems challenging the conventional statistical methods. These methods are based on the ability to obtain observations from unknown true probability distributions, whereas the new problems require recove

A comprehensive assessment of the impacts of climate change on agro- ecosystems over this century is developed, up to 2080 and at a global level, albeit with significant regional detail. To this end an integrated ecological- economic modelling framew

Over the past twenty years, the term agro-ecological zones methodology (AEZ) has become widely used for global regional and national assessments of agricultural potentials. The AEZ methodologies and procedures have recently been extended and newly im

Over the past twenty years, the term "agro-ecological zones methodology" (AEZ) has become widely used. However, it has been associated with a wide range of different activities that are often related yet quite different in scope and objectives. FAO a
