          Abstract

          Resumen Para comprender el comportamiento de los bosques ante el cambio climático es importante tomar en cuentan los procesos asociados con la funcionalidad de los ecosistemas forestales. En este trabajo de revisión se describen de manera general las tendencias en los cambios de la superficie forestal en México, destacando la capacidad de recuperación natural de los ecosistemas forestales. Dada la estrecha relación de los bosques y el agua, se incluye la relación de cambio de cobertura y escurrimiento superficial. También se destacan las principales perturbaciones de los bosques como consecuencia del cambio climático. Como aportación más relevante se enfatizan cinco procesos que son poco considerados en el tema de cambio climático, pero que definen la respuesta dinámica de los ecosistemas arbolados: la deficiencia hidráulica, eficiencia de uso de agua, la xilogenésis, los componentes de resiliencia e histéresis del ecosistema. La comprensión de estos puntos críticos ayuda en el entendimiento de la respuesta de los ecosistemas forestales ante el cambio climático. Una explicación científica del funcionamiento de los ecosistemas forestales ayudará a proponer estrategias específicas sobre manejo de estos ecosistemas y generar modelos con mayor capacidad de predicción de la dinámica de los bosques ante el cambio climático.

          Summary To understand how forests will behave under climate change, is important to consider the processes related to the functionality of forest ecosystems. In this review the trends of the forest area of Mexico is described in a general context, highlighting the natural recovery capacity of forest ecosystems. Given the strong connection between forests and water, the relationship between changes in cover and surface runoff is addressed. The main disturbances to forests as a consequence of climate change are also highlighted. As the most relevant contribution, five critical process are emphasized are that are seldom considered in the subject of climate change, but these process define the dynamics of forests ecosystems, namely: hydraulic failure, water use efficiency, xylogenesis, resilience components and ecosystem hysteresis. Understanding these critical points helps in understanding the response of forest ecosystems to climate change. A scientific explanation of how forest ecosystems work will help to propose specific strategies on the management of these ecosystems and generate models with greater and more realistic capacity to predict forest dynamics under the scenario of climate change.

          High-resolution global maps of 21st-century forest cover change.

          Quantification of global forest change has been lacking despite the recognized importance of forest ecosystem services. In this study, Earth observation satellite data were used to map global forest loss (2.3 million square kilometers) and gain (0.8 million square kilometers) from 2000 to 2012 at a spatial resolution of 30 meters. The tropics were the only climate domain to exhibit a trend, with forest loss increasing by 2101 square kilometers per year. Brazil's well-documented reduction in deforestation was offset by increasing forest loss in Indonesia, Malaysia, Paraguay, Bolivia, Zambia, Angola, and elsewhere. Intensive forestry practiced within subtropical forests resulted in the highest rates of forest change globally. Boreal forest loss due largely to fire and forestry was second to that in the tropics in absolute and proportional terms. These results depict a globally consistent and locally relevant record of forest change.

            A large and persistent carbon sink in the world's forests.

            The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 ± 0.4 petagrams of carbon per year (Pg C year(-1)) globally for 1990 to 2007. We also estimate a source of 1.3 ± 0.7 Pg C year(-1) from tropical land-use change, consisting of a gross tropical deforestation emission of 2.9 ± 0.5 Pg C year(-1) partially compensated by a carbon sink in tropical forest regrowth of 1.6 ± 0.5 Pg C year(-1). Together, the fluxes comprise a net global forest sink of 1.1 ± 0.8 Pg C year(-1), with tropical estimates having the largest uncertainties. Our total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks.

              Forests and climate change: forcings, feedbacks, and the climate benefits of forests.

              The world's forests influence climate through physical, chemical, and biological processes that affect planetary energetics, the hydrologic cycle, and atmospheric composition. These complex and nonlinear forest-atmosphere interactions can dampen or amplify anthropogenic climate change. Tropical, temperate, and boreal reforestation and afforestation attenuate global warming through carbon sequestration. Biogeophysical feedbacks can enhance or diminish this negative climate forcing. Tropical forests mitigate warming through evaporative cooling, but the low albedo of boreal forests is a positive climate forcing. The evaporative effect of temperate forests is unclear. The net climate forcing from these and other processes is not known. Forests are under tremendous pressure from global change. Interdisciplinary science that integrates knowledge of the many interacting climate services of forests with the impacts of global change is necessary to identify and understand as yet unexplored feedbacks in the Earth system and the potential of forests to mitigate climate change.
