The cultural landscape near the ancient city of Tharros (central West Sardinia): vegetation changes and human impact

The evolution of the cultural landscape in coastal western Sardinia is investigated by means of pollen analysis in the Mistras Lagoon sediments, near the ancient city of Tharros, with particular attention to changes in evergreen vegetation and the impact of human activity. The pollen diagram, spanning the time interval from 5300 to 1600 cal BP, documents the influence of man, climate, and geomorphic dynamics on the evolution of a semi-open evergreen vegetation landscape and variations in extent of a salt-marsh environment. Anthropogenic indicators and microcharcoals concur in depicting increased land use coinciding with the Nuragic, Phoenician, Punic and Roman dominations. Pollen data, along with archaeobotanical evidence, suggest a prevailing arable farming economy, vocated to Vitis and cereals exploitation, during the Nuragic phase until 2400 cal BP, replaced since then by a prevailing stock rearing economy. Between 2050 and 1600 cal BP, a less intensive human impact on the landscape is profiled, consistently with the archaeologically documented abandonment of the rural villages in favour of a slow urbanization, experienced by the Sinis territory in Imperial times. The pollen record provides new insights into the history of important economic plants in the Mediterranean, such as Vitis, Olea and Quercus suber. The results of the pollen analysis reveal how the records of these taxa are primarily influenced by the cultural development of the Sinis region and secondarily by dynamics involving the natural companion vegetation.     

Geographic film as public research: re-visualizing/vitalizing a terraced landscape in the Italian Alps (Piccola terra/Small land, 2012)

This article describes an experience of geographic filmmaking carried out within a long-term research process (2000–2012) involving the terraced landscape of the Brenta Valley in the Italian Alps. The documentary Piccola terra [Small land] (2012) was co-produced by geographers and professional directors. Engaging in the recent debate on filmic geographies, the aim of this article is to discuss and show what makes a film ‘geographic’. The geographer authored a filmic interpretation of landscape which is spatially and temporally complex, open and mobile, anchored to material features and to personal stories and socio-economic contexts. Produced to support a campaign for the adoption of abandoned terraces by ‘new farmers’, the documentary Piccola terra serves as a means to engage society and produce landscape change. Geographic filmmaking as an action-, public- and social-oriented activity is discussed with reference to the so-called ‘impact agenda’. We propose a style of active engagement through filmmaking which is workable, rather than critical. In order to avoid purely auto-reflective, auto-referential academic speculation on doing filmic and public geographies, this paper, which ideally is read along with viewing of the documentary, materially enters the researched/filmed landscape, developing into a supplementary tool for the international dissemination of Piccola terra.     

Observation and assessment of local economic development with regard to the application of the local multiplier

This contribution deals with the observation and evaluation of the issues of local economic development with a focus on the relatively new method of the local multiplier LM3. The main objective of this article is to evaluate the application possibilities of selected tools for the analysis of local economic development, in order to verify the effectiveness of the methodology of the local multiplier LM3 and to discuss the possibilities of its practical use. This LM3 method is perceived to be one of the convenient methods on how to capture certain components of local economic development. This indicator of the power of local economies is verified within field research in two case studies conducted in the ?umava region in Southwest Bohemia. The added value of this contribution is both methodological and practical. Currently, there exist only very few studies using the LM3 method in the Czech Republic and they do not offer satisfying evaluation of possible broader use of this method in the area of local development in the specific Czech regions. Having summarized two new case studies, this article contributes to the methodological discussion of the LM method and includes concrete practical recommendations for future research and also practical use.     

The Holocene fluvial history of the Tremithos river (south central Cyprus) and its linkage to archaeological records

This study aims to reconstruct the Holocene fluvial history of the Tremithos river, south central Cyprus and examine linkages to regional and local archaeological records. Three stratigraphic profiles (Sp1, Sp2 and Sp3) located in the lower valley have been investigated using sedimentology and magnetic parameters. The ¹⁴C dating of 10 samples reveals mid-Holocene ages for Sp1 and Sp2, while the upper most part of Sp3 can be attributed to the early to mid-Holocene. Two main phases of vertical accretion have been recognised: the first, recorded in the lower most part of Sp3, could not be dated but might relate to the late Glacial period. It is not associated with any archaeological artefacts. The second, recorded in all profiles, dating from ca. 5000 to ca. cal 2800 BC, spans the Late Neolithic Sotira (cal 4800/4000 BC) and Late Chalcolithic (cal 2900–2500 BC) cultures. The sediments of Sp1 and Sp2 are up to 8–10 m thick and mainly composed of fine material. However, an intercalated phase of coarse sediment has been identified at the beginning of the third millennium BC, indicating a sudden change in river dynamics, potentially associated with the 5.2 ka rapid climate change regional event. Typical mid-Chalcolithic (ca. cal 3300–3050 BC) ceramics found in a palaeosol in Sp2 indicate for the first time human occupation of the Tremithos river terraces. Two other palaeosols have also been recognised in Sp3 and radiocarbon dated to ca. cal 5600–4100 BC and ca. cal 2900–2600 BC, respectively. These results make it possible to propose a palaeogeographic reconstruction of the Holocene evolution in the Tremithos valley and to make a preliminary assessment of the relative roles of tectonics, climate and anthropogenic forcing.     

The Silverton Field Experience: a model geography course for achieving high-impact educational practices (HEPs)

High-Impact Educational Practices (HEPs) are a set of specific teaching and learning approaches proven effective in university education. This paper focuses on the benefits derived from utilizing three particular HEPs (inquiry-based collaborative activities, undergraduate research, and experiential learning) while teaching a snow and ice field course titled “Silverton Field Experience.” Student evaluations and instructor feedback reinforce the notion that HEPs encourage deep learning. Deep learning is manifest through increased enthusiasm and participation as well as learning in ways that are meaningful, creative, and stimulating. In terms of pedagogy in geography, these HEPs also create an expanded sense of place and a new way to encourage spatial thinking. The HEPs outlined here are replicable in different geography sub-disciplines and among different settings in higher education and prove exciting to an audience of pedagogic researchers and teacher-practitioners in geographical education.     

Reflections on the ESRC internship scheme for postgraduates

The Economic and Social Research Council (ESRC) in the UK is one of the main sources of funding for postgraduate study in human geography. For some years now, the ESRC has offered funded students the opportunity to apply to undertake a short internship in a government department or with a Non-Governmental Organization (NGO). This paper provides a collective reflection from the perspective of four former postgraduates who completed different ESRC supported internships in the UK. We discuss the enhancement of writing skills for diverse audiences, the advancement of knowledge in diverse subject areas, and the opening up of employment opportunities as key benefits of participating in the ESRC internship scheme.     

China’s new Eurasian ambitions: the environmental risks of the Silk Road Economic Belt

China is moving ahead with the Silk Road Economic Belt, an ambitious infrastructure development agenda with the distinct promise of regional and sub-regional economic development. However, the initiative will create new environmental risks across the entire Eurasian continent, especially in countries with predominately poor records of environmental governance, including the former Soviet republics and Russia. Concurrently, on the domestic front, the Chinese Government has launched a new policy paradigm, “ecological civilization,” to dramatically improve environmental regulations, reduce pollution, and transform industries by adopting new green technologies and higher environmental standards. But does China’s intention to go through a “green shift” domestically resonate with these new transborder infrastructure development mega-projects? This paper will attempt to answer this question by juxtaposing China’s new domestic policy paradigm with environmental standards currently proposed in its global outreach projects focusing on China-northern Eurasia and China-Russia, including trade exchanges in natural resources.

The Role of Surface Water Drainage in Environmental Change: a Case Example of the Upper South East of South Australia; an Historical Review

The role of surface water drainage in environmental change in Australia is rarely appreciated. Drains can modify surface water hydrology, not only altering flow regimes but also rapidly dispersing contaminants and altering the natural hydrological balance of associated flora and fauna. Yet drainage continues to be considered a viable management strategy rather than as a cause of land degradation. The impact of surface water drainage in an inherently saline area of South Australia, the Upper South East, is investigated. Surface water drains were constructed by developers in an attempt to increase the area of land available and viable for agricultural land use. Drainage strategies altered the natural direction, magnitude and frequency of surface water flow. The Upper South East has experienced periods of both increased surface water and flooding, and surface water deficit, in the past one hundred years. The region now receives less surface water than under pre‐European conditions, but local runoff is channelled into and through the wetlands more rapidly than before European settlement. Future management strategies are likely to continue this trend, to the detriment of remnant natural wetlands.
