It is better to start giving now then wait for some form of officially recognized strategy. You do the best you can to help the person temporarily because long term solutions take time. Long term solutions means everyone's support from government to corporations in planning, strategizing, taking action on poverty, disaster prone living condition because of environmental conditions. While we wait for that to happen people might become sick, die, become disabled because of the conditions they are in. Therefore it is not wrong or a better word wiser we do something to help alleviate the people's suffering while we wait for the experts to come in. If someone is dying we don't wait for ambulance to reach when we know of someone among ourselves who has some experience with medical rescue.
