Flood risk in Europe: the long-term outlook

Floods, storms and other hydro-meteorological events account for around two thirds of the damage costs of natural disasters, and these costs have increased since 1980, according to a recent EEA assessment of climate change impacts in Europe.The observed increase in damage costs from extreme weather events is mainly due to land use change, increases in population, economic wealth and human activities in hazard-prone areas and to better reporting. To confirm the exact role played by climate change in flooding trends in past decades, it would be necessary to have more reliable, long-time series data for rivers with a natural flow regime.

Adapting urban water systems to climate change

ICLEI, UNESCO-IHE and IWA have authored, as part of the ‘SWITCH – Managing Water for the City of the Future’ project, a handbook on adapting urban water systems to climate change. The handbook aims to fill a gap in the adaptation field: while a lot of information is available about various adaptation topics, there is a lack of guidance for decision makers at the local level working on urban water who wish to proactively prepare for and adapt to climate change. The handbook first examines some of the key areas of vulnerability to climate change within urban water systems. The handbook also proposes flexible and future-oriented urban water planning as a means to address climate change and implement adaptation actions. Finally, the handbook presents case studies of cities throughout the world that have already planned for adaptation or implemented specific actions aiming at increasing their resilience to climate change.

Integrated Assessment of Climate Security Hot Spots in the Mediterranean Region: Potential Water Conflicts in the Nile River Basin

The aim of this assessment paper is to identify the key links between climate change and security, and their potential for inducing resource conflicts and societal instabilities in the Nile river basin. The document notes that the differences in economic power between the upstream and downstream countries in the Nile River basin have evolved in the past and could become even more serious in the future. However, the large range of possible consequences of changes in climatic conditions for the flow rates of the Nile River can be attributed to the complexity of the river system.

Global threats to human water security and river biodiversity

Protecting the world’s freshwater resources requires diagnosing threats over a broad range of scales, from global to local. Here we present the first worldwide synthesis to jointly consider human and biodiversity perspectives on water security using a spatial framework that quantifies multiple stressors and accounts for downstream impacts. We find that nearly 80% of the world’s population is exposed to high levels of threat to water security. Massive investment in water technology enables rich nations to offset high stressor levels without remedying their underlying causes, whereas less wealthy nations remain vulnerable. A similar lack of precautionary investment jeopardizes biodiversity, with habitats associated with 65% of continental discharge classified as moderately to highly threatened. The cumulative threat framework offers a tool for prioritizing policy and management responses to this crisis, and underscores the necessity of limiting threats at their source instead of through costly remediation of symptoms in order to assure global water security for both humans and freshwater biodiversity.

Use of Geoenvironmental Impact of Climate Change in Management and Assessment Lake Nasser

This study monitor how to management the water stored after High Dam in the biggest artificial global lake (Lake Nasser), Integration of physical features and water level changes within the lake curse and margins. Statistical data presented, interpreted and correlated with using remote sensing technique in change detection. Different Landsat images acquired at different times (1970, 1982, 1987, 2000, 2003 and 2008) have been used by the ERDAS and ARC-GIS techniques to estimate the movements of lake borders and water fluctuation proportional to water sizes in place. Regards to water fluctuation degree, the lake can be divide into 4 classes in lake's sectors: 1, show maximum change degree, 2 show medium change degree, 3 slight to neglected change degree, and 4, no change. Functions control the water fluctuation in Lake Nasser are; (i) the granite and Nubia sandstone outcrops, (ii) NW, E-W and NE structure in order, (iii) low topography. Water level change detection on Landsat images in different dates elucidates big variation between different lake sectors, there are strangle points and other useful localities that yields environmental implication. The strangle points detected in the curse of River Nile and after 40 years since lake initiation, the water are more strangled in this curse because of the water velocity before the High Dam was high speed can pass toward the north in Nile annual flood but after the dam, the water velocity decreased. Due to decrease of velocity, the water go to narrow incised wadis (Khors) in the Nile high flood plus the sands drift, these khors are bounded by hard Nubia sandstone already saturated by water and it consider the main underground water reservoir in Egypt. In addition, the entrance of the lake in Halfa inside Sudan is subjected to suspended sediments (mud) forming new delta plus the sands drift that impair the reservoir in Egypt. Wadi Allaqui have 250 km length and 2 km average width, it's is the 5th order channel inside a large drainage basin that consider a recourses to the River Nile and hence to Lake Nasser. Wadi Allaqui have silt-soil with depth reach up to 5 meters. Kurkur have similar to Allaqi circumstance and support the Nile Basin.

Climate Change Adaptation Strategy and Programme of Action for the Palestinian Authority

The occupied Palestinian territory, as part of the Eastern Mediterranean, is subject to many serious changes in annual rainfall, mean temperature, extreme weather events and sea level rise as stated in the fourth assessment report by IPCC. The Palestinian National Authority, represented by the Environment Quality Authority (EQA), took the lead in developing the “National Climate Change Adaptation Strategy” with support from UNDP/PAPP. Stakeholders representing all scrotal groups, including officials, researchers, representatives of NGOs, CBOs and local communities, were actively involved in preparation of this national strategy. A National Committee for Climate Change is already active and working towards highlighting the impact of climate change on different sectors aiming at developing the National Action Plan for Adaptation. We are looking forward to cooperating with the international community to actively and properly adapt to the impact of climate change to protect our planet.

Spain, Water and Climate Change in COP 15 and Beyond: Aligning Mitigation and Adaptation through Innovation (WP)

The water/energy nexus opens a range of opportunities to align mitigation and adaptation framed by human security, which prioritises human development. In this context, Spain has an opportunity to play a leading role in realising this potential by pursuing a coherent multilevel strategy specifically designed for water and climate variability and change. Spain has a clear opportunity and, for practical policy reasons, a very clear self-interest in placing the water/energy nexus and the alignment of mitigation and adaptation high on the political agenda. The aim at COP-15 should be first for a global agreement and, as second best, a small multilateral group with Mediterranean and Latin American countries on the need to link water and climate change and variability. The second act will be the EU Presidency, where Spain can leave a legacy.

California climate adaptation stratege

In 2009, California adopted a statewide Climate Adaptation Strategy (CAS) that summarizes climate change impacts and recommends adaptation strategies across seven sectors: Public Health, Biodiversity and Habitat, Oceans and Coastal Resources, Water, Agriculture, Forestry, and Transportation and Energy. The 2009 CAS was the first of its kind in the usage of downscaled climate models to more accurately assess statewide climate impacts as a basis for providing guidance for establishing actions that prepare, prevent, and respond to the effects of climate change.

Climate change adaptation by design: a guide for sustainable communities

Drawing on research just published as part of the Building Knowledge for a Changing Climate programme, the guide uniquely considers how adaptation options are influenced by geographical location and the scale of development. It considers the interrelated roles of the planning system, communities, other stakeholders and delivery bodies. It seeks to ensure a better understanding of climate risks while demonstrating effective adaptation strategies through case studies from around the world. Case studies and guidance include: policy and legislative drivers for adaptation action both internationally and in the UK; a proposed framework for delivering adaptation action at the regional and local levels, together with some guidance on creating local adaptation strategies; a menu of adaptation options using practical examples, organized according to the main climate risks that communities in the UK face; technologies for climate risk management.

Assessing Climate Change Impacts on Water, Land-use and Economic Return in Agriculture

We develop a regional scale economic model for analyzing climate-change impacts on agriculture. Non-linear production functions describing yield responses to land allocation, water application and water salinity are integrated into a mathematical programming model. The responses to water quantity and quality are estimated by the use of scientific-based models simulating equilibrium in the root zone among plant's water uptake, soil salinity and soil's water content. Internalization of land allocation among crops is based on Howitt's PMP calibration approach (1995). The model, therefore, enables assessment of climate-change impacts on optimal agricultural management, where adaptation is considered endogenously with respect to both the extensive and intensive margins. The model is applied to the case of Israel. We divide the country into 14 regions and estimate regional future precipitation levels by implementing a climate-change down-scaling procedure. Then the model computes optimal agricultural managements under these projected rainfall levels. The results indicate a reduction of about 20% in statewide annual agricultural net-revenues by the year 2100 in comparison to 2002. Land allocated to field crops is increased on the expense of forages and vegetables. The shares of field crops and forages in the agricultural irrigation-water allotment are increased, while that of vegetables declines.

Climate Prediction for Adaptation: Who needs what?

The role of short- and long-term climate predictions in determining the success of adaptation to climate change is investigated. A simple theoretical model that captures the relationship between adaptive performance, decision structure, and prediction accuracy at different temporal scales is developed, and its implications deduced. It is shown that users who face high adjustment costs (i.e. are inflexible) depend more heavily on accurate long-term predictions than those who are able to adjust
