Warnings of increased UK flooding as a result of climate change
Intense bouts of flooding in the UK have increased substantially this century, with the frequency set to rise even further as a result of climate change. That is the latest warning from the Environment Agency, which said severe flooding over the last decade was linked to extreme weather events and rising sea levels. The agency highlighted Met Office data showing that there have been 17 ...

Mangroves for coastal defence
The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

Are traditional coping mechanisms effective in managing the risk against extreme events? Evidences from flood-prone region in rural India
Livelihoods of rural poor in developing countries like India are exposed to risks due to natural disasters like floods. Although these risks are covariate, households are affected in varying degrees due to their location and their relative capacity to cope with them. These in turn are household-specific and are decisive in defining the efficacy of coping mechanisms adopted by households to ...

Managerial response to sea level rise in the tidal estuaries of the Indian Sundarbans: a geomorphological approach
Tidal estuaries constrained by embankments in the Sundarbans have failed to respond to a >1 m sea level rise over the past 100 years since their construction. This paper shows that this has led to a disequilibrium morphology leading to channel erosion that has undermined embankments, causing mass failure, breaching and subsequent flooding during surge events. Predicted future sea level ...

What are the true costs of rising sea levels?
A simple relationship between sea level rise and the massive potential costs of future coastal flooding has been established by scientists in Germany. As sea levels rise, the damage to human economies rises even faster. And as sea levels rose by an estimated 14cms in the last century, and could rise by up to 130cms in this century, the coastal cities of the world could face huge bills for storm ...

Modelling climate change impacts on the flood pulse in the Lower Mekong floodplains
The flood pulse is a key element characterizing the hydrology of the Mekong River and driving the high ecosystem productivity in the Lower Mekong floodplains, both in the Cambodian lowlands and the Mekong Delta in Vietnam. This paper assesses the impacts of climate change, both in terms of changed basin water balance and sea level rise, on the Lower Mekong flood pulse. The impacts were simulated ...

Flood risks and environmental vulnerability — Exploring the synergies between floodplain restoration, water policies and thematic policies
Nowadays floodplain areas are reduced in size or no longer function as active floodplains, thereby impacting on the delivery of environmental services to local and regional communities and economies. These services include regulating services such as protection against floods or water purification; provisioning services, such as nutrient collection and fertile soil formation; and cultural ...

Appraising sustainable flood risk management in the Pearl River Delta's coastal megacities: a case study of Hong Kong, China
The Pearl River Delta (PRD) region has experienced rapid economic and population growth in the last three decades. The delta includes coastal megacities, such as Hong Kong. These low-lying urbanised coastal regions in the PRD are vulnerable to flood risks from unpredictable climatic conditions. These can result in increasing storm surges, rising sea level and intensified rainstorms causing ...

Impact of floods, hurricanes and storms
What happens to the water network in the wake of hurricanes and floods? Just days after Hurricane Harvey dumped over 50 inches of rain on the American state of Texas causing the deaths of 60 people and delivering billions of dollars worth of damage to homes and property, Hurricane Irma has wreaked havoc in the Caribbean with the most powerful Atlantic storm in recorded history. Hurricanes are ...

Public participation in flood risk management: the case of Germany
How can stakeholders best be involved in the implementation of the EU Floods Directive? According to recent research examining Germany as a case study, three types of strategy are being pursued across the country’s 16 federal states: the first draws on Water Framework Directive (WFD) procedures, the second meets only minimum requirements for participation and the third involves stakeholders ...

Are young people leaving themselves at risk of flooding?
According to recent figures from the Environmental Agency, young people in the UK may be leaving themselves at risk of flood damage. Around 75% of 18-24 year olds are not aware if they are living in an area at risk of flooding in the last year. Why is this so much of a problem and what can people do to find out how at risk their property is? With the number of properties in the UK at risk of ...

Scaling-up investments in natural infrastructure
Wetlands occur wherever water meets land. These deltas, marshes, rivers, lakes and watersheds are the water systems that link the natural world and human societies, and make it possible to clean, store and provide water to grow food and run businesses. As we prepare to participate in the 7th World Water Forum in South Korea, I want to bring attention to the need to scale up investments in ...
