It’s been ten years since the Wenchuan Earthquake struck China, leaving an everlasting scar on ravaged land, but also revealing the strong and unyielding will of the Chinese people.
Sun or rain? Most of us rely on the daily weather forecast to know what to wear or whether to bring an umbrella. However, for millions of people living in flood prone areas, timely and accurate forecasts, as well as early warning, can impact more than just clothing choices –they can help minimize flooding impacts.
Floods are the most frequent and damaging among natural hazards. Between 1980 and 2016, floods led to economic damages exceeding US$1.6 trillion, and more than 225,000 people losing their lives. Compounded by rapid urbanization and climate change, these losses will likely increase, especially in fast-growing countries.
‘Are we there yet?’ On a long road trip, perhaps you’ve asked or heard this question.
Let’s direct this question to the state of urban flood risk management in Pacific Island countries. In this case, the ‘destination’ is flood-resilient communities.
For Pacific Island countries, no, we’re not there yet, but are we heading in the right direction?
For many Pacific Island countries, natural disasters such as cyclones and tsunamis, are an all-too common occurrence. Out of the top 15 most at-risk countries for natural disasters globally, four are Pacific Island countries, and Vanuatu is consistently at the top.
In 2015, Cyclone Pam hit Vanuatu, and knowing the extent of damage was vital for the government to identify and plan reconstruction needs. A team of Unmanned Aerial Vehicle (UAV) experts were sent out to quickly establish credible estimates of the damages and losses. Many damage reports were already available from the field, but with varying quality, and the challenge was to consolidate and verify them, within a very tight timeframe. Cloud cover also prevented us from getting satellite images, so we mobilized two UAV teams to fly below the clouds and capture high-resolution footage showing the impacts on the ground in the worst affected islands in Tafea and Shefa province.
Challenges continued throughout, from needing to coordinate airspace with those flying relief goods into affected areas, to transferring massive datasets over low internet bandwidths. But with team-effort and ingenuity, solutions were found; the UAV teams were able to capture valuable damage footage within sampled areas during the day, which were analysed overnight by volunteers of the Humanitarian Open Street Map (HOT) and the Digital Humanitarian Network; new workflows were developed to collate the data and to feed the outputs into the Post-Disaster Needs Assessment.
Driving from the airport into the city of Apia, the capital of Samoa, is a great introduction to the country. Villages line the road with gardens filled with colorful flowers and palm trees. Hugging the northwest coastline, the road sometimes comes as close as five meters from the shoreline, giving passengers truly spectacular views of the Pacific Ocean.
While it’s a scenic introduction to Samoa, this drive is also a stark reminder of just how sensitive the country’s coastline is to erosion and damage. More than 50% of West Coast Road, Apia’s main roadway, sits less than three meters (9.8 feet) above sea level and just a few meters from the shoreline, making it highly vulnerable to damage and deterioration. When tropical cyclones, heavy rain, king tides and storm surges hit these coastal roads, they can lead to erosion, flooding and landslips, causing road closures and threatening the safety of the people who use them.
Setelah gempa bumi besar di Yogyakarta, Indonesia, pada tahun 2006, kawasan kota dan sekitarnya harus membangun kembali atau memperbaiki sekitar 300 ribu rumah.
Pemerintah punya pilihan menyewa 1.000 kontraktor yang masing-masing akan membangun 300 rumah, atau mengerahkan 300 ribu anggota masyarakat untuk masing-masing membangun satu rumah, rumah mereka sendiri.
Dengan pemerintah sebagai pemimpin proses rekonstruksi, mengambil pilihan kedua dalam mendukung program pemerintah. Ini adalah cara kerja REKOMPAK.
Following the massive earthquake in Jogjakarta, Indonesia, in 2006, the city and surrounding areas were faced with having to build or rehabilitate about 300-thousand homes.
The government had the option of hiring 1,000 contractors to build 300 houses each. Or we could have 300 thousand people working to build one house each - their own homes.
With the Government of Indonesia in the lead, we took the latter approach in supporting Indonesia’s efforts to rebuild communities. This is the REKOMPAK way.
