TL;DR: In the post-war years, hydrogeochemistry was influenced heavily by the advances in other disciplines including physical chemistry, metallurgy and oceanography, and important advances in analytical chemistry allowed multi-element and trace element applications to be made as discussed by the authors.

TL;DR: The integrated model introduced here dynamically describes the relationships between climate forcing, water availability, agriculture and selected societal processes and is applied to study the sensitivity of regional natural resources and socio-economy to climate change.
Abstract: Semi-arid regions are characterised by a high vulnerability of natural resources to climate change, pronounced climatic variability and often by water scarcity and related social stress The analysis of the dynamics of natural conditions and the assessment of possible strategies to cope with drought-related problems require an integration of diverse knowledge including climatology, hydrology, and socio-economics The integrated model introduced here dynamically describes the relationships between climate forcing, water availability, agriculture and selected societal processes The model has been designed to simulate the complex human-environment system in semi-arid Northeast Brazil quantitatively and is applied to study the sensitivity of regional natural resources and socio-economy to climate change The validity of the model is considered
Climate change is concluded to have an enormous potential impact on the region River flow, water storage and irrigated production are specifically affected, assuming a continuous regional development and unfavourable but plausible changes in climate Under plausible favourable changes in climate, these variables remain stressed The impact of the integrated model and its applications on present policy making and possible future roles are briefly discussed

TL;DR: Wang et al. as discussed by the authors focused on studying provincial disparity of China's water footprints and inter-provincial virtual water trade flows by adopting inter-regional input-output (IRIO) method and found that fast developing areas with larger economic scales such as Guangdong, Jiangsu, Shandong, Zhejiang, Shanghai and Xinjiang had the largest water footprints.

TL;DR: A first review of urban Africa's dependence on larger landscapes for water is presented in this paper, where changing water sources between 1970s and 1990s, industrial and domestic wastewater treatment and disposal, electricity generation's dependency on water is discussed.

TL;DR: In this paper, the authors present an assessment of stormwater runoff management practices to achieve urban water security, which can be achieved through optimal collection, infiltration and storage of storm water.
