Welcome to our guide on how to perform Search And Rescure for Globhe. All our Drone Operators must read the below and understand the details of a successful search and rescure operation during flooding events.
To fight climate change we need to make well-informed decisions based on accurate data. GLOBHE has gained experience in carrying out projects related to extreme weather events such as flood mapping and related data capturing and processing in different parts of the world.
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. It’s to be noted that the people involved in SAR activities need to be prepared to work during an emergency, with potential stressing conditions and distress.
Proper assessment of the situation saves time. Collect information on the extent of the damage and potential for future further damages. This can be done through visual inspection and verbal exchange with the local community. Rescue is a team effort that needs coordination and planning amongst the members for an optimum response operation.
Normally, the rescue operation is divided into different phases:
Floods are devastating extreme events on earth, which cause hazardous fatalities and demolish buildings and infrastructure throughout the world. They can be associated with landslides and mudslides. In case of flood events, people are generally forced to leave their houses and can be cut off from dry land by flooding. There have been many reasons that drive flooding to occur, including precipitation, inadequate capacity within banks, landslides, poor drainage, snow melt, and glacial outbursts. The increase in flood frequency worldwide is both natural and anthropic, caused by changes in meteorological conditions and land-use patterns. Heavy precipitation is the most common reason for the cases of tributary basins while tropical cyclones are one of the main reasons for perilous hydrology and weather around coastal regions.
In case of floods and cyclone disasters, the rescuers must be equipped with swimming and floating aids and should have enough swimming capacity for rescuing the drowning casualty. The rescuers must have knowledge and practice of swimming in order not to risk themselves whilst rescuing the victims.
In order to mitigate the impact of floods on the population, a proper flood planning and management strategy is critical. Globhe operate both in the pre, during and post phase of floodings. Rapidly occurring flood disasters require a quick response time as well as fast and coordinated actions of governing authorities and SAR actors. In practice, flood mitigation strategies can be categorized into three phases of flood occurrence:
Pre-flooding anticipation activities are carried out in order to have better preparedness for flood events. An appropriate pre-flood strategy can improve public safety, alleviate social damages and minimize economic losses associated with floods. Preparedness is defined as establishing an effective action to the initial adverse indicator of hazards (resulting, e.g., from environmental and weather changes), including assigning timely reliable early warnings and pre-allocation for temporary spaces for refugees and their belongings from the catchment areas.
When flooding occurs, establishing rapid and effective SAR actions is key to reducing the effects of the flood disaster in the context of financial losses and further suffering of the flood victims. This phase includes activities of bringing suffering people from the risk zone to a safe zone, supplying food, water, medicine, and shelter, monitoring the flood situation, etc. The aim of the SAR operation is to manage the overall likelihood and negative impacts of flooding on people, the economy, and the environment.
Flood relief operations for affected people are the main task in the aftermath of flood events. Establishing effective planning and enlisting relief operations can benefit greatly in mitigating the suffering. Flood relief operations can take many forms that include establishing emergency facilities, distributing aid, transferring injuries, taking effort to restore public facilities and houses of the affected areas to its original state, and so on.
Effective communication technologies play an important role in providing a desirable solution in any circumstance of a natural disaster like a flood. Studies suggest that the first 72 hours post-disaster (called the “golden relief time”) are extremely important. After the golden relief time, the probability of finding survivors is rapidly becoming lower. Consequently, communication is vitally important to efficiently coordinate rescue efforts during this critical window. Various information and communication technologies such as remote sensing, Geographical Information Systems (GIS), and Global Positioning Systems (GPS) are widely considered for a disaster management system. Since drones are fast and can access remote and hard-to-reach locations in a matter of minutes, they can be efficiently used to develop emergency communication networks for SAR missions and aid the rescue process in disaster areas.
The main objective of disaster response is to secure lives and livelihoods first. To achieve that, the competent authorities need accurate information regarding disaster areas to make a quick decision right after the disaster.
The 3 levels of remote sensing you can achieve are:
There are still several variables that can impact the drone’s ability to find a missing person. But at the base of them lies speed. The faster we can get there, the faster we can find them, and the faster we can deliver them to definitive care, the better the chance of survival.
Depending on the needs and locations, GLOBHE's operators are expected to:
Here are some important steps to follow before, during, and after starting a SAR mission:
