Book Description
Leaded gasoline is still one of the main sources of Pb particles deposition in soils and vegetation near highways and major roads. The effect of road distance, wind directions, and land use types (LUTs) on Pb distribution was studied in soils and vegetation samples collected along the main road in Shweifat. The effect of some soil characteristics (pH. CaCOj, soil organic matter and soil textural classes) was also assessed. Soil and plant samples were acid-digested and Pb levels were determined. Statistical analysis revealed a significant relationship between soil Pb levels and distance from the road, soil textural classes (silt and sand), pH, and LUTs. Soil Pb concentrations was negatively correlated with the distance from the road, clay and silt content, and positively correlated with pH, LUTs, and sand percentages. Pb in plant samples was only affected by distance from the road with a negative correlation between the two. In both, soil and plant samples, the mean Pb level was highest at 3 meters distance with mean levels of 115 ppm and 26 ppm respectively, thus indicating that the motor vehicle is the main source of this Pb contamination. LUTs were also significantly related to mean soil Pb concentration, with urban areas having the highest mean Pb level (113 ppm) in comparison with agricultural and vacant areas. No relation between plant Pb levels and LUTs was observed. pH was found to positively affect soil Pb levels, with higher Pb concentration at high pHs. Soil textural classes, mainly sand percentage, were found to be associated with soil Pb distribution caused mainly by the high affinity of Pb to the sesquioxides, goethite, hematite that are normally coating on the sand grains. No correlation was observed between soil Pb and plant Pb implying that Pb is not available for plant uptake in soils. Soil and plant may be used to reflect the extent of aerial deposition of Pb in the roadside and in different LUTs.

Book Description
Book Description:Water resources in the Middle East are barely enough to cope with human demand, and their scarcity is a matter of discussion in many conclaves. However, it must be clarified that Lebanon has a rugged topography that sets it apart from the surrounding regions. Its small area of 10,452 km2 is characterized by a mountainous terrain marked by several valley systems. Two mountain chains (Mount Lebanon to the west and Anti-Lebanon to the east) extend parallel to the Mediterranean Sea, and are separated by the Bekaa Plain, which comprises a relatively wide depression. Hence, Lebanon has many sources of surface water including rivers, springs, snowfalls and lakes; besides, many aquiferous rock formations and karstic conduits exist where groundwater can accumulate via seeping.However, complaints concerning the lack of understanding about the imbalanced water supply/demand in Lebanon are often a matter of debate, and the water budget is also not well-formulated yet. Added to the matter of water shortage and deterioration in quality thereof, challenges for water resources have only exacerbated. Thus, there are parallel paths stemming from both natural and human driving forces leading to increasing water stress. Climate change, pollution, over-exploitation and the mismanagement of trans-boundary water resources are amongst the geo-environmental problems that affect these resources. In particular, shared water is one of the major water problems in Lebanon.To put this issue into perspective, more than 74% of Lebanon's border is shared with neighbouring countries, which makes the surface and groundwater intermingle with neighbouring regions; thus, no volumetric measures are known. Two shared rivers exist between Lebanon and its neighbours: one with Syria in the north, and the other with the Palestinian Territory (PT) in the south. In addition, the three major aquiferous rock formations of Lebanon are interrelated with neighbouring regions.To date, there is no credible study to assess and allocate the shared water resources. Consequently, geo-political conflicts frequently arise due to the obscure nature of the hydrologic conditions. In addition, the absence of treaties and agreements is another reason affecting water sharing, which constitutes the principal cause of water loss. This is totally governed by the unstable political situation in the region.This book aims to highlight the principles of Lebanon's water resources with new numeric measures. It will also reveal the major elements of the striking challenges. Thus, the fundamental hydrologic aspects of shared water resources in Lebanon, including quantitative measures and the spatial extent of these resources will be illustrated.

Book Description
This book covers aspects of groundwater resource characterisation and management. The inherent heterogeneous and isotropic nature of aquifers coupled with the unpredictable effects of climate change calls for continuous improvement and understanding of hydrogeology site characterisation techniques in theory and application to better understand and manage groundwater. We believe that this book will be useful for various professionals involved in groundwater-related work to improve the theoretical and practical understanding of hydrogeology site characterisation techniques and groundwater resource management skills.

Book Description
Visual Imagery and Human Rights Practice examines the interplay between images and human rights, addressing how, when, and to what ends visuals are becoming a more central means through which human rights claims receive recognition and restitution. The collection argues that accounting for how images work on their own terms is an ever more important epistemological project for fostering the imaginative scope of human rights and its purchase on reality. Interdisciplinary in nature, this timely volume brings together voices of scholars and practitioners from around the world, making a valuable contribution to the study of media and human rights while tackling the growing role of visuals across cultural, social, political and legal structures.

Book Description
This study looks at environmental problems from the perspective of the victims. The bottom line consequences are often damaging to the health of individuals or communities and they raise a wide range of issues concerning justice, international and environmental law, public health, occupational health and health policy, social policy and welfare, international relations and security. All of these issues are addressed by the contributors, and the work is designed for a spectrum of readers, whether concerned with industrial hazards and occupational health, relevant agreements or treaties, environmental refugees, or the roles of state, business and other actors.

Book Description
"While water professionals have been advocating comprehensive water reforms for years and many countries have improved their water policies and institutions, some of the most politically sensitive elements of reform remain untouched. This report suggests that a series of factors are now emerging that represent a potential opportunity to break this impasse." "Making the Most of Scarcity will be of interest to readers working in the areas of agribusiness and markets, agriculture, urban and rural development, water supply, and water resources, as well as to those responsible for setting policies in the areas of environment, economics, and social protection."--BOOK JACKET.

Book Description
In recent years, especially with the approach of the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change in Paris in late 2015, the number of publications, conferences and meetings on climate change has been growing exponentially. Yet uncertainties remain concerning rural tropical areas where models are forecasting the onset of multiple disorders and trends are unclear. Meanwhile, the impact of climate change on the poorest communities is regularly documented, often prompting alarmist reactions. How can food security be achieved while adapting to and mitigating climate change? What are the main threats to agriculture in developing countries? How do farmers in these countries cope with the threats? What does agricultural research propose? What options have yet to be investigated? A broad scope of scientific research is underway to address these challenges. Diverse solutions are available, including new agricultural practices, water management, agricultural waste recycling, diagnosis of emerging diseases, payment for ecosystem services, etc. Gaining insight into the financial and political mechanisms that underlie international climate negotiations is also essential to design practical ways to deal with climate issues and meet sustainable development requirements in collaboration with farmers. This book pools the wealth of experience of dozens of researchers and development officers from a range of disciplines. We have focused on making it detailed, accurate and hopefully easy to read for researchers, students and all other informed readers.

Book Description
The late twentieth and early twenty-first centuries are commonly characterised as an age of ‘neoliberalism’ in which individualism, competition, free markets and privatisation came to dominate Britain’s politics, economy and society. This historical framing has proven highly controversial, within both academia and contemporary political and public debate. Standard accounts of neoliberalism generally focus on the influence of political ideas in reshaping British politics; according to this narrative, neoliberalism was a right-wing ideology, peddled by political economists, think-tanks and politicians from the 1930s onwards, which finally triumphed in the 1970s and 1980s. The Neoliberal Age? suggests this narrative is too simplistic. Where the standard story sees neoliberalism as right-wing, this book points to some left-wing origins, too; where the standard story emphasises the agency of think-tanks and politicians, this book shows that other actors from the business world were also highly significant. Where the standard story can suggest that neoliberalism transformed subjectivities and social lives, this book illuminates other forces which helped make Britain more individualistic in the late twentieth century. The analysis thus takes neoliberalism seriously but also shows that it cannot be the only explanatory framework for understanding contemporary Britain. The book showcases cutting-edge research, making it useful to researchers and students, as well as to those interested in understanding the forces that have shaped our recent past.
