Humanitarian access and corridors explained

In most wars, the biggest threat to civilians is not only the fighting itself but the loss of food, water, medicine and power. Reports about “humanitarian access” describe whether help can reach the people who need it.

What access means

Humanitarian access has two sides: aid organisations being able to reach people in need, and people in need being able to reach aid, such as a clinic or a distribution point. Under international humanitarian law, parties must allow and facilitate rapid and unimpeded passage of impartial relief for civilians, subject to their right to check what is being delivered.

What blocks access

Active fighting on roads and in towns.
Checkpoints and permits. Convoys may need approval from several authorities and armed groups, each of which can delay or refuse.
Damaged infrastructure such as bridges, ports, airports and fuel supplies.
Attacks on aid workers, which lead agencies to suspend operations.
Bureaucratic restrictions on visas, imports and bank transfers.
Insecurity on the way, such as looting of convoys or unexploded ordnance on roads.

Humanitarian corridors

When fighting surrounds a town, the parties sometimes agree on a named route, opening hours and safety guarantees so that people can leave or supplies can enter. Such corridors are only as safe as the parties make them. Reports that a corridor has “opened” or “failed” usually come from the parties first; confirmation from the UN or the ICRC, which often escort or observe such movements, is a stronger sign.

Who delivers aid

Aid in conflict areas is delivered by a mix of organisations: UN agencies such as the World Food Programme, UNICEF and UNHCR; the Red Cross and Red Crescent Movement, including the ICRC and national societies; international non-governmental organisations; and, very often, local groups and volunteers who already live in the area. Local responders usually reach people first and stay the longest, but they also face the greatest risks and receive the least funding. Coordination meetings, usually led by OCHA, try to make sure that different organisations do not duplicate work or leave gaps.

Other ways aid gets in

When roads are blocked, agencies may try air drops, sea routes or cross-border operations from neighbouring countries. These are usually more expensive and deliver less than road convoys, so they are signs of how hard access has become rather than a solution to it.

How to read aid reports

Statements about the number of trucks or tonnes delivered are useful, but they only make sense compared with what is needed and with what reached people before the crisis. Look for reports from UN agencies such as OCHA and from aid organisations working on the ground.
