A different perspective to donations that you make towards disaster relief.
Donating to large international NGOs usually means that a lot of foreign relief aid will be imported into the affected countries. Most disasters, even the large scale ones are rather isolated. Flood and earthquake areas rarely extend over 10 km, and there will be local businesses which are open for business post disasters, but they will be excluded from relief by the international NGOs. Businesses in the foreign countries will be the ones who benefit from the disaster.
In the long run, these aids do affect the local economies adversely and your well-meaning donations will cause harm to the financial ecosystem. What’s worse is that some international organisations are managed off site in another country and bureaucracy may cause massive waste and inefficiencies.
