Spatially-explicit land cover land use change (LCLUC) models are becoming increasingly useful tools for historians and archaeologists. Such kinds of models have been developed and used by geographers, ecologists and land managers over the last few decades to carry out prospective scenarios. In this paper, we review historical models to compare them with prospective models, with the assumption that the ample experience gained in the development of models of prospective simulation can benefit the development of models having as their objective the simulation of changes that happened in the past. The review is divided into three sections: in the first section, we explain the functioning of contemporary LCLUC models; in the second section, we analyze historical LCLUC models; in the third section, we compare the former two types of models, and finally, we discuss the contributions to historical LCLUC models of contemporary LCLUC models.

Marx’s concept of metabolic rift has emerged as a prominent theoretical framework with which to explain the socioecological crises of capitalism. Yet, despite its relevance to key concerns in critical environmental geography, it has remained marginal within the field. Here we address this by distinguishing between metabolic rift theory and two predominant Marxist approaches in environmental geography: the production-of-nature thesis and posthumanist world ecology. We follow this comparative assessment with a detailed analysis of metabolic rift theory and a brief overview of how the concept relates to key concerns in critical environmental geography. We conclude by discussing how a stronger engagement with the metabolic rift approach could benefit the field. Key Words: Marxism, materialist dialectic, nature–society relationship, production of nature, world ecology hybridism.

French Marxist sociologist, Henri Lefebvre, was one of the foremost social theorists of the twentieth century, celebrated for his critiques of everyday life, urban revolution, and the production of space. We argue here that his mature work also encompassed a theory of ecological crisis, drawing directly on Marx’s theory of metabolic rift. In this conception, the dialectics of nature and society were subject to alienated capitalist accumulation, giving rise to metabolic rifts, epochal crises, and new historical moments of revolutionary praxis aimed at the metamorphosis of everyday life. Lefebvre thus ranks as one of the foundational contributors to environmental sociology, whose rich theoretical analysis offers the possibility of a wider social and ecological synthesis.

El presente artículo tiene por objetivos revisar el devenir histórico y la historiografía del concepto geográfico paisaje, a fin de mostrar su pertinencia operativa en los estudios ambientales, mediante el análisis homeostático de sus elementos tanto biofísicos como socioculturales. Para ello, ponderamos la utilidad de un enfoque epistémico monista —el paisaje como una totalidad en la que no hay separación de sus componentes—, frente al dualismo manifiesto en la dicotomía naturaleza- sociedad, común en pensamiento científico dominante, que poco contribuye a un entendimiento cabal del medio, en un contexto de emergencia ecológica global.

Henri Lefebvre's intricate material-dialectical approach to the nature-society problematic, taken together with his advocacy of a praxis oriented to total transformation from the ground up through autogestion, offers a unified, critical, and dialectical approach to political ecology. Unfortunately, his work in these areas has too often been interpreted as divided and fragmentary, splitting his radical analysis of the production of space-time from his critical praxis related to autogestion. We offer a corrective to this by elaborating briefly on his use of Marx's material-dialectical approach, outlining how Lefebvre brings this method to bear on the nature-society problematic, and how his theorization of autogestion points to a radical praxis aimed at overcoming the social-ecological contradictions of capital. His engagement with Marx's theory of metabolic rift, and his advocacy of a radical project of autogestion as part of the critique of everyday life, serve to place the underlying issue of alienation in spatial terms, offering geography a transformative perspective that avoids positing closed systems and attempting to exhaust the various meanings assigned to nature. In this, Lefebvre demonstrates how the nature-society problematic overflows issues of ontological framing and language, calling for a unity of radical theory and practice to overcome the separations.

Humanity’s present social–ecological metabolic configuration is not sustainable, and the need for a radical transformation of society to address its metabolic rifts with the rest of nature is increasingly apparent. The work of French Marxist Henri Lefebvre, one of the few thinkers to recognize the significance of Karl Marx’s theory of metabolic rift prior to its rediscovery at the end of the twentieth century, offers valuable insight into contemporary issues of sustainability. His concepts of the urban revolution, autogestion, the critique of everyday life, and total (or metabolic) revolution all relate directly to the key concerns of sustainability. Lefebvre’s work embodies a vision of radical social–ecological transformation aimed at sustainable human development, in which the human metabolic interchange with the rest of nature is to be placed under substantively rational and cooperative control by all its members, enriching everyday life. Other critical aspects of Lefebvre’s work, such as his famous concept of the production of space, his temporal rhythmanalysis, and his notion of the right to the city, all point to the existence of an open-ended research program directed at the core issues of sustainability in the twenty-first century.
