Displaying 45 of about 2013 resultsOn August 14, 2017, landslides and floods devastated a large cross-section of Freetown, Sierra Leone. An estimated 6,000 people were affected, of which 1,141 have been reported dead or missing. More than 3,000 people lost their homes. Almost every sector of the urban economy was impacted. The livelihood impacts of affected communities were widespread.…
From January to April 2015, Mozambique experienced prolonged heavy rain, which contributed to the rising of water levels in the Zambezi, Licungo and Shire River basins, exposing the population to flooding. Factors which contributed to the high level of flooding are: (i) heavy rainfall; (ii) flat terrain; (iii) high tide; and (iv) inappropriate drainage…
During the night of 13-14 June 2015, heavy rainfall over the Vere River basin led to flash floods that struck the Vake and Saburtalo neighbourhoods of Georgia’s capital, Tbilisi, as well as other areas of the city along the right bank of the river Mtkvari. The Lisi, Tsodoreti, Napetvrebi, Bevreti, Tskhaldidi, Betania and Tskhneti areas around Tbil…
A slow-moving tropical depression caused persistent heavy rains in the Solomon Islands between April 1 and April 4, 2014. The rains caused flash flooding in Honiara, Guadalcanal, Isabel, Malaita,and Makira-Ulawa. The flooding was the worst in living memory in some locations. It caused 22 fatalities across the country, internally displaced some 10,000 pe…
This paper draws upon recent research in Ba Town to examine the drivers, patterns, and impacts of internal displacement linked with disasters. Disasters have triggered around 153,000 displacements in Fiji, since IDMC started systematically collecting data in 2008. Rapid urbanisation, particularly the growth of informal settlements, is increasing ex…
The world’s coastlines are at the forefront of climate change. That’s because they’re constantly changing, and respond quickly to changes in climate. They’re particularly important because around 70% of the world’s population live within 100km of the coast, and 90% of the world’s trade passes through ports on the coast. The global ec…

The first day of monsoon in the state also saw the first instance of waterlogging throwing life out of gear in congested low-lying locales of the Old City while the rest of the city experienced merely a pleasant drizzle, throwing light on the misplaced priorities in urban development during times of changing rainfall patterns.

This study adopts the 1D–2D model SOBEK to investigate the impact of drainage density on river flow. Coupled 1D–2D hydrodynamic models are widely utilized in food hazard mapping. Previous studies adopted conceptual hydrological models or 1D hydrodynamic models to evaluate the impact of drainage density on river flow. However, the drainage density a…
Urban floods are becoming more common as a result of increasing urbanisation, poor urban planning, and climate change. A new report by PlanAdapt explores how the cities of Cape Town, Durban, Mombasa and Nairobi are rising to the challenge, and how their work can inspire others.
Understanding flood management
Flooding poses a significant threat…
The frequency of thunderstorms in some fast-growing African coastal cities has doubled over the past 30 years, with much of this increase linked to the impact of deforestation on the local climate, a study has found.
It is widely known that removal of vegetation increases rainwater runoff and the risk of mudslides, which happened in Sierra Leone’s capi…
This study explores the concept of buildings as the smallest unit of urban space, wherein the distribution characteristics of risk factors were examined by building use as an adaptable measure for urban flooding disasters. Flood risk is calculated as a function of hazard, exposure, and vulnerability. The flood risk for a building was classified into fiv…
80% of cities face severe impacts from climate change.
But innovative solutions offer the prospect of protections from extreme events.
In the fight against climate change, cities matter. Today, over half of humanity lives in cities and by 2050 seven in ten of us will be urban dwellers. So what can be done to prepare cities for climate change?
As d…
This study aimed at exploring the perception on flood risk and ascertaining the determinants of disaster preparedness among residents in flood-prone urban communities. Descriptive statistics and discriminant regression model were employed on primary data collected from 240 urban households across five communities at risk of flooding in the study area.…
Three years ago, a historic rush of water surged into this city, inundating restaurants and churches, tossing boats onto streets, and leaving Venetians distressed about a future with ever more extreme events. But this past week, one of those events arrived — a tide nearly as large as 2019’s — and residents barely noticed, aside from some wind and rain.…
Background
The tragic consequences of the earthquake that struck Haiti on 12 January 2010 mainly stem from a lack of awareness of the seismic threat combined with the extreme vulnerability of the country’s urban centers. Haiti’s exposure to earthquakes and other natural hazards such as hurricanes, floods, landslides, or tsunamis is very high. Their imp…
