The new scientific decade (2023-2032) of the International Association Hydrological Sciences (IAHS) aims at searching for sustainable solutions to undesired water conditions - may it be too little, much or polluted. Many current issues originate from global change, while problems must embrace local understanding and context. will explore crises by actionable knowledge within three themes: interactions, innovative cross-cutting methods. We capitalise on previous IAHS Scientific Decades...
Mediterranean grasslands of southwest Spain and Portugal are a crucial part the largest agroforestry ecosystem in Europe, known as dehesa Spain. This multi-use system is recognized to be balanced combination environmental economic values. Grasslands contribute both aspects, with high diversity plant species, providing essential feeding resources for extensive livestock, primary activity many these areas. Water availability main limiting factor growth region, production closely linked its...
The Mediterranean oak savanna is Europe's most extensive agroforestry system, with significant economic, social, and ecological relevance. Climate models indicate that the region particularly vulnerable to impacts of global warming, which include increased frequency severity droughts. Consequently, there a pressing need for conservation measures prevent degradation this ecosystem, reduce uncertainty about production, ensure its sustainable development. One valuable resources system acorn...
The headwaters catchments of the Sierra Nevada mountain range in Southern Spain are a clear example Mediterranean where climate variability enhances spatiotemporal complexity snow dynamics. changeable patterns snowfall combined with usually mild and sunny winters result shallow snowpacks that favor various accumulation melting cycles and, consequently, appearance characteristic patchy distribution. Remote sensing techniques has proven to be most effective solution monitor this Among...
Dehesas, a biodiversity-rich Mediterranean agro-silvopastoral ecosystem with seasonal water availability, are highly sensitive to changes in both climatic conditions and management practices. While droughts naturally occur, climate change exacerbates scarcity, leading i) low unpredictable pasture tree production, ii) decreased quality shrub encroachment, iii) oak decline, mortality, lack of natural regeneration, iv) increased soil exposure degradation nutrient losses. These impacts...
Mediterranean agrosilvopastoral ecosystems (MAEs), such as the Dehesa/Montado in Spain (SP)/Portugal (PT), Meriagos Italy (IT) and valonia oak forests Greece (GR), provide essential environmental services play a significant role supporting local communities, their economies, well-being. However, MAEs are highly vulnerable to impacts of climate change effects, including rapid warming heat waves, prolonged droughts with intermittent sudden heavy rainfall mediterranean hurricanes (medicanes)...
Water management in basins where natural flow regime is altered by the presence of reservoirs a complex issue that often requires development modelling tools to support managers their decision-making process. However, when it comes large necessary satisfy different demands vast and heterogeneous territory, which pressures on basin water resources are increased due effects climate change, makes challenging matter. It these cases possible use long series data hydro-meteorological variables...
Savannas are among the most variable, complex and extensive biomes on Earth, supporting livestock rural livelihoods. These water-limited ecosystems highly sensitive to changes in both climatic conditions, land-use/management practices. The integration of Earth Observation (EO) data into process-based land models enables monitoring status, improving its management conservation. In this paper, use Two-Source Energy Balance (TSEB) model for estimating surface energy fluxes is evaluated over a...
It is well documented that energy balance and other remote sensing-based evapotranspiration (ET) models face greater uncertainty over water-limited tree-grass ecosystems (TGEs), representing nearly 1/6th of the global land surface. Their dual vegetation strata, grass-dominated understory tree-dominated overstory, make for distinct structural, physiological phenological characteristics, which challenge compared to more homogeneous energy-limited ecosystems. Along with this, contribution...
A very simple remote sensing-based model for water use monitoring is presented. The acronym DATTUTDUT (Deriving Atmosphere Turbulent Transport Useful To Dummies Using Temperature) a Dutch word which loosely translates as "it's unbelievable that it works". fully automated and only requires surface temperature map, making to providing rapid estimate of spatially-distributed fluxes. algorithm first tested over range environmental land-cover conditions using data from four short-term field...
Mediterranean oak savannas (known as dehesas in Spain) are exposed to numerous threats from natural and economic causes. A close monitoring of the use water resources status vegetation these ecosystems can be useful tools for maintaining production ecological services. This study explores estimation evapotranspiration (ET) stress over a dehesa by integrating remotely sensed data into balance using FAO-56 approach (VI-ETo model). Special attention is paid different phenology contribution...
The body size of specimens Triturus marmoratus pygmaeus from Doñana is the smallest recorded for this subspecies. Snout‐vent length averages 42.3 mm in males, and 43.9 females. Mean mass males 2.04 g 2.29 age newts was estimated by means skeletochronological methods. maximum longevity 10 years females nine with one or two being at maturity. As other newts, not a good predictor age, since wide range found within each class. Growth substantial subsequent years, showing an overall positive...
Dehesas are highly valuable agro-forestry ecosystems, widely distributed over Mediterranean-type climate areas, which play a key role in rural development, basing their productivity on sustainable use of multiple resources (crops, livestock, wildlife, etc.). The information derived from remote sensing based models addressing ecosystem water consumption, at different scales, can be used by institutions and private landowners to support management decisions. In this study, the Two-Source...
Abstract. Drought is a devastating natural hazard that difficult to define, detect and quantify. The increased availability of both meteorological remotely sensed data provides an opportunity develop new methods identify drought conditions characterize how changes over space time. In this paper, we applied the surface energy balance model, SEBS (Surface Energy Balance System), for period 2001–2018, estimate evapotranspiration other fluxes dehesa area Iberian Peninsula, with monthly temporal...
The use of soil moisture (SM) measurements from satellites has grown in recent years, fostering the development new products at high resolution. This opens possibility using them for certain applications that were normally carried out situ data. We investigated this hypothesis through two main analyses high-resolution satellite-based (SBSM) combined microwave with thermal and optical data: (1) Disaggregation based on Physical And Theoretical scale Change (DISPATCH) and, (2) Soil Moisture...
Abstract. In Mediterranean oak-savannas (known as dehesas in Spain), it is important to better understand the interactions between vegetation structure and local climate regulation at scales relevant farm management dominant hydrological regime. This study evaluated water use patterns of dehesa patches (open grasslands, lowland grasslands with high soil moisture, tree + grass, riparian vegetation), estimating actual evapotranspiration (ET). We used different models, previously validated...
A two-source model for deriving surface energy fluxes and their soil canopy components was evaluated using multi-angle airborne observations. In the original formulation (TSEB1), a single temperature observation, Priestley—Taylor parameterization vegetation fraction are used to derive component fluxes. When observations made from different angles, temperatures can be extracted directly. Two dual angle versions compared versus TSEB1: one incorporating (TSEB2I) directly (TSEB2D), which data...
Savannas are among the most productive biomes of Africa, where they comprise half its surface. They support wildlife, livestock, rangelands, crops, and livelihoods, playing an important socioeconomic role in rural areas. These water-limited ecosystems with seasonal water availability highly sensitive to changes both climate conditions, land-use/management practices. Although monitoring programs for African savanna use have been established certain areas, them largely restricted point based...
