The relationship between values and knowledge in visioning for landscape management: relevance for a collaborative approach

Abstract Respecting connections between the diversity of values and forms of knowledge is essential to support a decision-making that fosters relationships between ecosystems and people. However, little theory has been developed for clarifying interactions between values and knowledge, and their relevance for environmental policy. We surfaced the overlooked relationship between values and knowledge by studying […]

Late Holocene climatic variability in Southern Spain deduced from the sedimentary record of Laguna Grande de Archidona

Abstract The southern Iberian Peninsula has been especially sensitive to Holocene climate changes [1]. Climatic and environmental variability has been reconstructed by the mineralogical and chemical analyses of lacustrine sediments. In this study we show the preliminary chronological, lithological, geochemical and magnetic susceptibility results of the sedimentary record of the Laguna Grande de Archidona (southern […]

NAO control on the hydrology of Laguna Grande de Archidona (southern Spain) during the Iberian Roman Humid Period recorded by stable isotopes (δ18O and δD) of gypsum hydration water 

Abstract The North Atlantic Oscillation (NAO) has a major effect on the modern precipitation patterns in the southern Iberian Peninsula and also controlled the hydroclimate of this region in the past [1,2]. The oxygen and hydrogen stable isotopes (δ18O and δD) of lake waters are sensitive to long-term changes in hydrological conditions (e.g. relative humidity, […]

Abrupt lowstands of Laguna de Zoñar (southern Spain) during the Iberian Roman Humid Period recorded by stable isotopes of gypsum hydration water

Abstract Centimeter-thick layers of gypsum (CaSO4·2H2O) were deposited at the bottom of Laguna de Zoñar (Córdoba Province, southern Spain) from ~2120 to ~1900 cal yr BP [1], coinciding with the apogee of the Roman Empire in the Iberian Peninsula. The presence of gypsum deposits in lake sediments is generally interpreted as evidence of dry climatic […]

Holocene paleoenvironmental evolution of a playa-lake system in southwestern Iberia (western Mediterranean region)

Abstract The Mediterranean region is a vulnerable area affected, among other environmental threats, by aridification and desertification processes that can cause soil salinization in areas rich in evaporite deposits. This is especially evident in the evaporite lake systems of southern Iberia, where a combination of both natural and anthropogenic causes gives rise to aridification and […]

Mountain permafrost in the Central Pyrenees: insights from the Devaux ice cave

Abstract  Ice caves are one of the least studied parts of the cryosphere, particularly those located in inaccessible permafrost areas at high altitudes or high latitudes. We characterize the climate dynamics and the geomorphological features of Devaux cave, an outstanding ice cave in the Central Pyrenees on the French-Spanish border. Two distinct cave sectors were […]

Late Quaternary climate change in Australia's arid interior: Evidence from Kati Thanda – Lake Eyre

Abstract Williams Point is an iconic late Quaternary sedimentary sequence exposed at the southern margin of Madigan Gulf at Kati Thanda – Lake Eyre (KT-LE), Australia's largest lake. The ∼15 m high cliff outcrop includes 6 m of aeolian sediments, capping a ∼0.5 m beach/shoreline facies containing abundant Coxiella (aquatic gastropod) unconformably overlying 5–6 m of fluvio-lacustrine facies. The base of the outcrop […]

Life adapted to uncertainty: Drylands ecology

Abstract Drylands occupy approximately 40 % of the Earth's surface. Their peculiar hydrological regime, with water as the main limiting factor, together with other characteristics, such as the variability of rainfall and their ecological heterogeneity, turn these regions into one of the main and most relevant sets of biomes on the planet. Beyond their stereotypical conception […]

Forest restoration is more than firing seeds from a drone

Abstract We are witnessing a rapid increase in news sending the message that drone seeding is a promising technological solution to implement forest restoration at large spatial scales. However, there are neither reports regarding success nor peer-reviewed studies to support these assertions. Once in the ground, the seeds and the seedlings and saplings that they […]

Climate legacies drive the distribution and future restoration potential of dryland forests

Abstract Knowing the extent and environmental drivers of forests is key to successfully restore degraded ecosystems, and to mitigate climate change and desertification impacts using tree planting. Water availability is the main limiting factor for the development of forests in drylands, yet the importance of groundwater resources and palaeoclimate as drivers of their current distribution […]
