Increasing water scarcity has posed a major constraint to sustain food production in many parts of the world. To study the situation at the regional level, we took Iran as an example and analyzed how an intra-country "virtual water trade strategy" (VWTS) m ...
This paper deals with the definition and determination methods of the soil-water retention surface (SWRS), which is the tool used to present the hydromechanical behaviour of soils to highlight both the effect of suction on the change in water and total vol ...
Summary and conclusion: In this report, we first study evaporation and condensation on alpine glaciers. We present two models of ice evaporation and we compare them with observations. We afterwards estimate the impact of ice evaporation in present and futu ...
Although generally accepted as a necessary step to improve water management and planning, integrated water resources management (IWRM) methodology does not provide a clear definition of what should be integrated. The various water-related issues that IWRM ...
Temporary water transfers, as achievable under option contracts, capture gains from trade that would go unrealized if only permanent transfers of water rights were possible. This paper develops a bilateral option contracting model for water which includes ...
1.Many studies have identified relationships between plant reproductive behaviour and environmental conditions. However, they have all been based on cross-species analysis and take no account of the relative abundance of species with vegetation. 2.Using tw ...
Decreasing water availability per capita in more and more countries is the result of bad management over the past centuries. The 'world water crisis', however, is not inevitable. The concept of Integrated Water Resources Management (IWRM) has been promoted ...
Urban stormwater is an important source of detrimental impacts for receiving waters. Discharges from separated or combined sewer systems are recognized as a major contamination input to the environment. Moreover, these discharges may impact the morphologic ...
As a response to the continuous increase of use on fertilizers and pesticides in last decades related to agricultural practices, the European Union (EU) has adopted in 1991 the Nitrate Directive 91/676/EEC (EU 2000). More recently the “Water Framework Dire ...
This paper estimates a translog cost function for Swiss water utilities. From the cost function, we are able to estimate measures of marginal costs as well as economies of production density, customer density and scale, which are important determinants in ...
