This paper provides an overview of the latest developments in methodologies for assessing the vulnerability of coastal zones to climate change at regional and local scales. The focus of vulnerability assessment in coastal zones used to be on erosion and land loss due to sea-level rise. Methodologies now increasingly consider the wide range of climate and impact variables that play a part in det...

this interdisciplinary paper aims at guangzhou’s development and its effects on surface andgroundwater quality taking the new city axis as an example. qualitative morphological analyses, field mappings, interviews and water sampling of standard in-situ and various hydrochemical parameters were conducted between 2007 and 2009 in order to examine the following research questions: which types of l...

This paper focuses on vulnerability of rural households to poverty when a negative crop shock occurs. Of particular concern is the possibility of some sections experiencing long spells of poverty as a consequence of such shocks. The analysis is based on the ICRISAT panel survey of households in a semi-arid region in south India during 1975-84. Using alternative specifications that take into acc...

Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...

Th ere is noticeable negative impact on soil and water quality caused by nutrient leaching, especially nitrate. Five regions in Croatia are preliminary delineated as nitrate vulnerable zones, including potentially vulnerable zones (PVZ) and vulnerable zones (VZ), one of them being Varaždin County. Agricultural land spreads on 59% of its total area. Th e survey was carried out to analyze two ava...

It is well known that rivers connect upstream and downstream ecosystems within watersheds. Here we describe the concept of precipitationsheds to show how upwind terrestrial evaporation source areas contribute moisture for precipitation to downwind sink regions. We illustrate the importance of upwind land cover in precipitationsheds to sustain precipitation in critically water stressed downwind ...

Aim Range-restricted species account for a large proportion of global biodiversity, and many such species are highly threatened by deforestation and intensifying land use in the tropics. The effects of land use on the diversity of rangerestricted species have rarely been studied and remain unknown for vascular epiphytes – diverse and important elements of tropical forests. This study analyses t...

• The role played by the state as a land market regulator in urban areas with natural vulnerability to flooding; as a producer of urban land and housing; and as a builder of defenses against flooding. • Impacts on the land market of flooding and built defenses as well as access to urban land for different population sectors; land value increases and decreases in urban areas according to floodin...
