“…Nonetheless, climate change represents an additional factor that, along with the growing demand for resources, land-use change and pollution, are pressuring natural systems. Climate change will not affect everyone to the same degree; developing countries and the most vulnerable social groups will be the most affected (Mateos et al, 2016). In the Mesoamerican and Caribbean regions, challenges in this regard are growing Muñoz-Jiménez et al, 2019).…”

“…This phenomenon can be particularly dramatic in tropical ecosystems and has been documented to occur in a variety of locations worldwide (Allen et al, ; Chazdon, Brenes, & Alvarado, ; Condit, Hubbell, & Foster, ; Khan, Rodgers, Johnsingh, & Mathur, ; Laurance et al, ; Leigh, Windsor, Rand, & Foster, ; Lwanga, ; Phillips et al, ; Rolim, Jesus, Nascimento, do Couto, & Chambers, ; Williamson et al, ). In México, where close to 30% of the nation surface is covered by tropical and subtropical ecosystems, substantial changes in the climatic variability with potential damaging effects for the integrity of these ecosystems have been reported (de la Mora Orozco et al, ; Jauregui, ; Mateos, Santana, Montero‐Martínez, Deeb, & Grunwaldt, ).…”

The hydrology and productivity of the ecosystems of the Yucatan Peninsula (YP) are highly constrained by two factors: (a) the lack of surface drainage networks due to the existence of a highly permeable and connected karstic aquifer roughly the size of the peninsula and (b) a climatic gradient that leads to a transition from seasonally dry deciduous and sub‐deciduous tropical forests, in the north‐western and central parts of the Peninsula, to evergreen forests, in the southern and eastern parts. As a result, surface water fluxes of the YP are restricted to evapotranspiration (ET) that are tightly coupled to ecosystems health and gross primary productivity (GPP). The magnitude and seasonal variation of these fluxes are sensitive to climatic variability and perturbations caused by extreme events such as droughts and tropical storms that are frequent in the YP. In this study, we assess the spatio‐temporal dynamics of ET and GPP above average dry and wet conditions through time series analyses of 15 years of remotely sensed data from both Moderate Resolution Imaging Spectroradiometer and Tropical Rainfall Measuring Mission satellite products. Our results show that ET and GPP follow a regional moisture and temperature gradient that highly controls the distribution of ecosystems within the peninsula. We observe that ET and GPP are in phase with the rainy season in the deciduous forests, but for the evergreen forests, only the GPP is in phase. Additionally, and with the exception of droughts on deciduous ecosystems of the northern part of the YP, the productivity of these ecosystems shows a legacy effect, responding more to a defined trajectory (wetting or drying on the previous years), rather than to punctual extreme climatic events. This has implications on the resilience of these ecosystems to natural perturbations of climate. Comparisons between deciduous and evergreen forest indicate that both types of ecosystems have different plant water use strategies in response to hydrologic variability.

“…In turn, exposure to ECE is monitored by the Centro Nacional de Prevención de Desastres (National Centre for Disaster Prevention, CENAPRED), which generates publicly available geographic information that maps differences in exposure to diverse ECE throughout the territory (CENAPRED, 2012(CENAPRED, , 2016. However, few studies have researched how LULCC map onto ECE, and the role of climatic variability as another driving force of land degradation and a potential amplifier of its effects in arid and semi-arid ecoregions (although, see Englehart and Douglas, 2004;CONAFOR-UACh, 2013;Mateos et al, 2016).…”

RESUMENLas tierras áridas y semiáridas representan el 60% del territorio mexicano. Además de albergar a diversas especies endémicas, concentran una gran proporción de la población y ofrecen a sus habitantes servicios ecosistémicos cruciales. Sin embargo, los impactos de actividades productivas han generado procesos de degradación y desertización, acentuados por la alta sensibilidad de estos sistemas a la variabilidad climática. La información sobre los procesos de cambio en el uso del suelo y los impactos de la variabilidad climática en las regiones áridas y semiáridas de México se encuentra dispersa en diferentes documentos y es necesario hacer un ejercicio de integración para entender las sinergias en el territorio y brindar información más completa para la toma de decisiones. En ese sentido, este estudio integra la información sobre cambios en el uso del suelo y cobertura vegetal en cinco ecorregiones áridas y semiáridas de México (sonorense, chihuahuense, tamaulipeca, Altiplanicie mexicana y valle de Tehuacán-Cuicatlán) para el periodo 2002-2011, y su exposición actual a sequías, bajas temperaturas, inundaciones y ciclones tropicales. Discutimos estos resultados en términos de las tendencias climáticas regionales documentadas en la literatura, lo que nos sirve de marco de referencia para analizar las interacciones entre esos factores. Encontramos que el cambio de uso de suelo y pérdida de cobertura vegetal difiere entre ecorregiones, siendo la sonorense y la chihuahuense las menos afectadas. Por otra parte, a excepción de la ecorregión del valle de Tehuacán-Cuicatlán, todas las ecorregiones presentan grados de exposición altos a eventos extremos, aunque cada una presenta un perfil distinto. Las tendencias climáticas observadas en estas ecorregiones apuntan hacia un aumento tanto de temperaturas máximas como mínimas; las tendencias para precipitación son menos claras. Nuestros resultados son un punto de partida para ubicar las áreas con procesos antrópicos de cambio de uso de suelo y eventos climáticos extremos, con el fin de identificar posibles sinergias entre estos dos estresores y plantear un mejor manejo de estas áreas en un contexto de cambio global. ABSTRACTArid and semi-arid lands in Mexico dominate 60% of the national territory. They harbor many endemic species, as well as a large proportion of the population, and offer diverse ecosystem services. These regions are subjected to anthropogenic impacts derived from agriculture and livestock farming, which have caused land degradation and desertification. In addition, these ecosystems are highly sensitive to climate variability and projected global environmental change.
