Measuring magnitude and rate of vertical movements in the offshore Capo Vaticano (W Calabria) using lowstand coastal prisms and wave-built terraces

2012

The magnitude and rate of vertical movements have been measured in the offshore Capo Vaticano (western Calabria) for the Late Pleistocene - Holocene on the basis of the depth of submerged coastal prism and associated wave-built terrace formed during the sea-level lowstand of the Last Glacial Maximum (LGM). Uplifted and submerged terraces have proved to be valuable recorders of vertical motion in many locations around the world (e.g. DICKINSON, 2001; WEBSTER et alii, 2004) as the depth of their tops appear to be controlled by the sea-level. In the eastern Tyrrhenian margins, depending on the hydraulic energy conditions (i.e. waves and wind-induced currents), the average water depth of terrac…

An Inventory Approach to the Assessment of Main Traditional Landscapes in Sicily (Central Mediterranean Basin)

2012

EU policy for the conservation of cultural landscapes is of particular importance for a region such as Sicily (Italy) which is the site of many Mediterranean traditional cultural landscapes as well as new landscapes created by contemporary agriculture. Such variety of landscape, however, is not supported or confirmed by specialised inventories that identify and classify the typical Main Traditional Landscape (MTL). On the basis of these considerations, the objective of the present paper is to draw up a preliminary inventory and present a brief characterisation of MTLs in Sicily, in line with the multidisciplinary experiences and approaches implemented at European and national levels. In def…

Spatial Extent of vertical tectonic motions in northern Sicily using Holocene and Last Interglacial sea level markers: a case study between Acquedolc…

2010

Vertical position of sea-level, related deposits and morphologies (e.g., last interglacial, LIG, 125ka,) provide useful markers to utilize with this purpose (LAMBECK et alii, 2004; FERRANTI et alii, 2006, ANTONIOLI et alii, 2009). Using published (ANTONIOLI et alii, 2006) and new data we provide a review of the northern coast of Sicily uplift rates. The markers used in this study are: terraces inner margin, tidal notches, etc., and, for the last millennia archaeological markers and fossil beaches and vermetid reef. Data on vertical movements calculated for the coastal area developing in the north-Sicilian continental margin indicate that, from East to West, a strong variation of vertical ra…

Olive agroforestry systems in Sicily: Cultivated typologies and secondary succession processes after abandonment

2011

The first part of this study provides an overview on Sicilian olive systems. Subsequently, the study describes the different typologies of cultivated agroforestry systems present in South-Eastern Sicily employing olive trees in association with other Mediterranean tree species, in particular for the production of firewood, coal and animal food (downy or pubescent oak, holm oak, cork oak), but also in association with forage or grazing species (oat, barley, vetch, etc.) or cereals. The study shows that Sicilian agroforestry systems are much more diversified than it was known so far. In the second part, the study describes the spontaneous colonization processes by plants, observed in abandone…

An empirical test of neighbourhood effect and safe-site effect in abandoned Mediterranean vineyards

2011

The importance of both neighbourhood effect and safe-site effect for the colonization of Mediterranean old fields by woody plants was investigated. Using a transect approach, we recorded colonization of 21 species of woody plants on abandoned, terraced vineyards on Pantelleria Island (Sicily) in dependence from neighbouring terraces in older succession stages (Maquis) and available safe sites for seedling establishment (former crop plant, terrace wall). With a paired design of four treatments, including presence/absence of adjacent older successional stages, and North-/South-facing slopes, a neighbourhood effect could be shown for both expositions if the transect started from an adjacent fi…

Lluvias torrenciales y cambios geomórficos en una pequeña cuenca de montaña : el barranco de la Cuesta de la Vega (Valencia)

2013

In this paper the effects of great magnitude -450 mm.- as well as high continued intensity -> 90 mm. for 3h.- storm-rains have been studied for a small mediterranean drainage basin (Ayora, Valencia). Such rains caused anormal flows -between 11.2 y 38.2 m3/sec/km2- and the reactivation of erosiona! and aggradational processes, especially at flat bottomed valleys with terrace culture, where new channels were formed. Severa! types of deposits and erosiona! phenomena are established; among them valley amplitude, local slopes, culture abandonment (in a positive sense ), and valley floor terracing are pointed out.

Geomorphology of the Capo San Vito Peninsula (NW Sicily): An Example of Tectonically and Climatically Controlled Landscape

2017

The Capo San Vito peninsula is located along the north-westernmost sector of the Sicilian coastline. It is characterized by a complex geomorphological setting, where a large variety of coastal, gravity-induced and karst landforms allow the visitor to easily detect the interactions between Quaternary tectonics and climate changes as well as morphodynamic processes responsible for shaping the landscape. Thanks to natural reserves, the peninsula preserves a typical Mediterranean natural environment, marked by spectacular and suggestive landforms.

Muyong and subak. Farm production, cultural heritage and environmental challenges in the terraced rice fields of Bali, Indonesia and the Ifugao count…

2017

The terraced rice fields of Bali and the northern Philippines are not just spectacular agricultural production sites located in hilly or mountainous areas. Their development by the Hindu Balinese and the non-Christianized Ifugao includes a strong religious dimension as well as a complex social organization around the management of water resources. The recent rise of tourism, coupled with the UNESCO world heritage recognition of these agricultural areas, leads today to several challenges that may jeopardize the balance of these societies: tourism overcrowding, loss of authenticity, abandonment of farming by young people. Are these sophisticated local farming systems sustainable in the contex…
