How does intact ecosystem reduce the disaster risk?
How does intact ecosystem reduce the disaster risk?
First, ecosystems, such as wetlands, forests and coastal systems, can reduce physical exposure to natural hazards by serving as natural protective barriers or buffers and thus mitigating hazard impacts.
What is the meaning of disaster prevention and mitigation?
Mitigation means to reduce the severity of the human and material damage caused by the disaster. Prevention is to ensure that human action or natural phenomena do not result in disaster or emergency.
What do natural disasters do to populations in ecosystems?
Earthquakes, landslides, volcanic eruptions and natural bush fires all affect the many different ecosystems on our planet. Initially, these disasters negatively affect the biodiversity of wetlands, forests and coastal systems by causing the spread of invasive species, mass species mortality and loss of habitat.
Which ecosystem is more resistance to natural calamities?
Ecosystems such as wetlands, forests, and coastal systems can provide cost-effective natural buffers against natural events and the impacts of climate change. 3. Healthy and diverse ecosystems are more resilient to extreme weather events.
Who is involved in Cbdrm?
Involving Children and Youth Children and youth are increasingly participating in CBDRM and HVCA. This can have many benefits; it not only directly involves children and youth in dealing with disasters – including adapting to climate change – but can also enhance the resilience of entire communities.
Why prevention and mitigation is important?
Mitigation and prevention efforts aim to reduce the potential damage and suffering that disasters can cause. While disaster management cannot prevent disasters, it can prevent them from becoming compounded as a result of neglecting causal factors and manageable risks.
What is the balanced chemical equation for photosynthesis?
Ans: Photosynthesis is the process by which plants, in the presence of chlorophyll trap the energy of the Sun, absorb water, and carbon dioxide to produce oxygen and energy in the form of sugar. The balanced chemical equation is as follows: Q.3. Why is 12 H 2 O used in Photosynthesis?
What is the step by step process of photosynthesis?
Step by Step Process of Photosynthesis. 1 Step 1. The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the 2 Step 2. 3 Step 3. 4 Step 4.
How is oxygen liberated as a by-product of photosynthesis?
Oxygen is liberated as a by-product and light is considered as a major factor to complete the process of photosynthesis. Photosynthesis occurs when plants use light energy to convert carbon dioxide and water into glucose and oxygen.
What is called the dark reaction stage of photosynthesis?
Ans: Photosynthesis takes place in two stages – Light-dependent reaction stage and Light independent or dark reaction stage. The dark reaction stage is also known as the Calvin cycle. Light is not required in this stage of the photosynthesis process, hence the name dark reaction.
