The Costs Of Residential Water Scarcity In Cyprus: Impact Of Climate Change And Policy Options, Theodoros Zachariadis May 2010

The Costs Of Residential Water Scarcity In Cyprus: Impact Of Climate Change And Policy Options, Theodoros Zachariadis

Theodoros Zachariadis

This paper presents an assessment of the costs of water scarcity in Cyprus, today and in the next twenty years, accounting also for the effect of projected climate change in the region. We focus on the residential sector, accounting also for tourism and industry. Using a simple demand function we first compute total scarcity costs in Cyprus for the entire period 2010¡V2030 for three scenarios of future water demand. Our central estimate shows that the present value of total costs due to water shortages in this period will amount to 72 million Euros (at 2009 prices), and if future water …


An Analysis Of Temperature Variations Using Remote Sensing Approach In Lokoja Area, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, Sunday Ishaya Mr Jan 2010

An Analysis Of Temperature Variations Using Remote Sensing Approach In Lokoja Area, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, Sunday Ishaya Mr

This study investigates the thermal variations of the different land use/cover types in urban Lokoja town retrieved from Landsat TM imagery of 1987. Band 2, 3, 4 and 6 of the imagery were used in the classification, estimation of NDVI, land surface emissivity values, and satellite sensor temperature. The Qin et al’s mono window algorithm was employed to obtain the land surface temperatures of the different land use/cover types classified. The results indicate that there is a significant variation in temperatures among the different land use/cover types in Lokoja. The built up area and the vacant area have the highest …

The objective of this work is to present a critical review of the application of the tissue residue approach (TRA) in ecological risk and/or impact assessment (ERA) of chemical stressors and environmental criteria development. A secondary goal is to develop a framework for integrating the TRA into ecological assessments along with traditional, exposure concentration-based assessment approaches. Although widely recognized for its toxicological appeal, the utility of the TRA in specific applications will depend on numerous factors, such as chemical properties, exposure characteristics, assessment type, availability of tissue residue-response data, and ability to quantify chemical exposure. Therefore, the decision to use …


Meeting The Common Needs Of A More Effective And Efficient Testing And Assessment Paradigm For Chemical Risk Management, Steven P. Bradbury, Vicki Dellarco, Tala Henry, Phil Sayre, Jennifer Seed Jan 2010

Meeting The Common Needs Of A More Effective And Efficient Testing And Assessment Paradigm For Chemical Risk Management, Steven P. Bradbury, Vicki Dellarco, Tala Henry, Phil Sayre, Jennifer Seed

Steven P. Bradbury

Significant advances have been made in human health and ecological risk assessment over the last decade. Substantial challenges, however, remain in providing credible scientific information in a timely and efficient manner to support chemical risk assessment and management decisions. A major challenge confronting risk managers is the need for critical information to address risk uncertainties in large chemical inventories such as high- and medium-production-volume industrial chemicals or pesticide inert ingredients. From a strategic and tactical viewpoint, an integrated approach that relies on all existing knowledge and uses a range of methods, including those from emerging and novel technologies, is needed …
