One of the major challenges facing Jordan is its severe shortage of water resources: water scarcity is the norm. The consequences of water scarcity in Jordan are made more harsh by several developments related to strategy, policy and society, the most significant being the rapid rise in population. The population of Jordan has increased tenfold since the 1950s. In addition to the high rate of population growth, Jordan has seen a series of massive refugee influxes since 1948, most importantly the influx of Palestinian refugees over the past decades and currently over a million Syrian refugees. A new book, «Water Resources of Jordan», sheds light on the problems Jordan faces and aims to bring suggestions for possible solutions.

29 June 2018 • The northeastern United States is experiencing rapid changes in its hydrology due to intense land-use change, urbanization, and climate change. It also possesses some of the highest density, longest term observations of hydrologic variables (streamflow, groundwater levels) in the US and the world. The focus of this presentation is how small unconfined aquifer systems, and the streams to which they are connected, respond to hydroclimatic and land use changes. 2018 Birdsall-Dreiss Lecture: Groundwater as a Buffer to Climatic Change: Dynamic Subsurface Storage of Glaciated Landscapes

The book »Groundwater around the world« presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater—a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. As a result of a cooperation between author Jac van der Gun and Michael van der Valk | Hydrology.nl the book is now available as a free PDF file!

Питна вода з-під крана, всі на велосипедах і відсутність поняття «сміття». Про те, що для українця – дивина, а для жителя невеличкого чеського міста – буденність, розповіла кореспонденту «СК» харківська науковиця Юлія Виставна.

Water legislation in Georgia, Moldova and Ukraine is under transformation from Soviet to EU environmental standards. This shift requires significant changes in the terminology, structure and content of water laws. At present, the main shortcomings of the water legislation of the three countries and its practical implementation are: (1) fragmentation of water legislation, which translates into poorly defined responsibilities; (2) significant discrepancies between different laws on property rights and the responsibilities of natural resource users; and (3) outdated water quality standards. A new paper by Yuliya Vystavna, Maryna Cherkashyna and Michael van der Valk describes the changes needed to transform the water legislation in Georgia, Moldova and Ukraine from Soviet to EU environmental standards.

12–15 February 2018, Heidelberg • SnowHydro 2018 – International Conference on Snow Hydrology. Snow is an important component of the hydrological cycle. The seasonal storage of water in the snowpack may last over months, and its retarded release is a major factor of reliable water supply for ecosystems and human needs during dry periods. Rapid snow melt can however cause destruction through sudden floods, mostly in combination with rainfall. Thus, water demanding downstream regions, settlements and infrastructures are highly vulnerable with regard to the presence or absence of snow in the headwaters. Increasing air temperatures and changing precipitation patterns driven by climate change will modify snow conditions and thus lead to changing water supplies. Snow cover is also a critical factor in global and regional energy balances. The consequences of reduced snow duration and an increasing share of rainfall on precipitation will completely change the land-atmosphere interactions and thus lead to further modifications of the regional climatic conditions.

As an essential foundation for achieving inclusive growth, sustainable infrastructure underpins all economic activity. Inadequate infrastructure remains one of the most pervasive impediments to growth and sustainable development, and consequently in tackling poverty. Good infrastructure unshackles and removes constraints on economic growth and helps increase output and productivity. Investment in sustainable infrastructure can help generate employment, boost international trade, industrial growth, and competitiveness while reducing inequalities within and among countries.

久负盛名的鄱阳湖是中国最大的淡水湖，夏日雨季时的面积达到洛杉矶的三倍以上。它是稀有的长江江豚的家园，在冬季，它的滩涂是成千上万鸟儿的首要觅食地，其中包括极度濒危的西伯利亚鹤，它们每年秋天飞向南方，逃离西伯利亚的寒流。现在鄱阳湖本身也处于濒危状态。
