Our primary goal is to develop an integrated, quantitative assessment tool evaluating how human economic activities influence spatial patterns of urbanization, and how land-use change resulting from urbanization affects stream water quality and aquatic ecosystem health. Here we present a prototype of a holistic assessment tool composed of three “building blocks” simulating the social and economic structures, spatial pattern of urbanization, and watershed health as determined by various metrics. The assessment tool is applied to Dutchess County, New York and two of its largest watersheds, Wappinger and Fishkill Creek watersheds, demonstrating how an explicit link can be established between human economic activities and ecosystem health through changes in land use.

Rivers have played a defining role in the global development of human societies and culture. This will undoubtedly continue in the twenty-first century with a growing demand for water, increasing pollution of river channel and floodplain environments, and anthropogenic global warming-related changes in the frequency of floods and droughts. These will have major environmental and societal impacts worldwide. We consider how rivers initially shaped societies, and then how urbanisation, industrialisation and intensified agriculture have more recently transformed river systems, so compromising planetary health and human ways of life. So where do we go from here? Humanity now faces an existential environmental catastrophe of its own making, and it will be on the world's most densely populated floodplains where this crisis will be played out. We highlight likely areas facing the greatest challenges. Ironically, many of these are where ancient civilisations began. Interdisciplinary catchment-based approaches, and new technologies such as those based on satellite imagery and unmanned aerial vehicles, are now beginning to address pressing societal and planetary problems in the unfolding climate crisis.

The broad aim of this paper is to look at the relationship between terrain and conflict. Using the opportunity and willingness framework, it argues that there are some long established physical factors, which have been related to the terrain of conflict, but that there are also some equally long established factors that are nonphysical. This latter group includes the notion of a “mountain people,” which is described as being fierce, uncivilized, and resistant to authority. Such arguments may have some foundation, but they are also based on a strong history of determinism and indeed scientific racism. The paper also looks at the “what is a mountain?” debate and argues that this question is entirely misleading for conflict analysis. It is hoped that conflict researchers will be careful whenever they encounter the word “mountain.”

Mobile games and ICT-based mixed reality tools offer significant opportunities for tourism. This chapter reviews the existing literature in both these areas, and presents a novel way of combining games and virtual reality into an interpretive tool. As a complex, threatened marine ecosystem, Australia’s Great Barrier Reef faces significant interpretive challenges, and almost no new interpretive tools have been developed over the last 30 years. Here, the authors unpack the stages and interdisciplinary approach required to design the tool and highlight how it might fit within the broader scope of ICT developments in tourism. We outline areas of future research, with a particular focus on how ICT might contribute to making nature-based tourism more sustainable, by finding fun, innovative ways to engage tourists in the conservation of some of our most iconic natural assets.

This chapter describes the climatic setting of the Aral Sea region, investigates how the climate might change during the 21st century, and discusses potential impacts on water resources. Temperature and precipitation fields are analyzed to describe the mean climate for the Aral Sea region. Composite analysis has been employed on the precipitation field from the Global Precipitation Climatology Project (GPCP v2.2) to assess the spatial pattern of changes in precipitation during the last several decades. Furthermore, temperature and precipitation projections available from the 2007 Intergovernmental Panel on Climate Change report are synthesized to examine the nature of climate change during this century.

Cold season precipitation has increased during recent decades, particularly over the mountainous terrain east of the Aral Sea. Climate models also project increases (5−20%) in winter precipitation during the 21st century; however, several models suggest decreases (0 to −15%) in precipitation during summer. Despite the increases in cold season precipitation, the large increases in temperature (4°C) during the 21st century are likely to cause increased evaporation which could exacerbate the regional water budget deficit. This may constrain the water supply in the region, particularly during summer and autumn when water demand is highest. To fully understand the impacts of future climate change on regional water resources, hydrologic models that include anthropogenic management of water will be required.

Although there have been extensive studies on the hydrological and erosional impacts of logging, relatively little is known about the impacts of conversion into agricultural plantation (namely rubber and oil palm). Furthermore, studies on morphological impacts, sediment-bound chemistry and forensic attribution of deposited sediment to their respective sources are scarcer. This chapter introduces the potential for using the multi-proxy sediment fingerprinting technique in this context. Featuring pilot projects in two major flood-prone river systems in Malaysia, the studies explore application of geochemistry-based sediment source ascription. The geochemical signatures of sediment mixtures on floodplains were compared to sediments from upstream source tributaries. The tributaries were hypothesised to have different geochemical signatures in response to dominant land management. The first case study took place in the Segama River system (4,023 km²) of Sabah, Malaysian Borneo where a mixture of primary forest, logged-forests and oil palm plantations were predominant. The second case study was in the Kelantan River Basin (13,100 km²) with two major tributaries (Galas River and Lebir River) where logged-forests and rubber and oil palm plantations are dominant land-uses. Both case studies demonstrated the applicability of this method in ascribing floodplain deposited sediment to their respective upstream sources. Preliminary results showed that trace elements associated with fertilisers (e.g. copper and vanadium) contribute to agricultural catchment signatures. Alkaline and alkaline-earth elements were linked to recently established oil palm plantations due to soil turnover. Mixing model outputs showed that contributions from smaller, more severely disturbed catchment are higher than those from larger but milder disturbed catchments. This method capitalises on flood events to counter its adverse impacts by identifying high-priority sediment source areas for efficient and effective management.
