To promote hisÌýSunday column, Nick KristofÌýtweeted the following:

The tweet raises the question:ÌýAre 800,000 people eating just leaves* in the Nuba Mountain? Kristof writes:

According to the Sudanese government, just under 1.1 million people live in South Kordofan state, where the Nuba Mountains are located. If Boyette's estimates are correct, that means three quarters of the people living in the region are have run out of food. AÌýReuters articleÌýfrom mid-May puts the number much lower:

It seems that 100,000 seems to be a more appropriate estimate which also closely mirrors the 10% severe malnutrition rate that Kristof reports as having been recorded at the Yida refugee camp in South Sudan. The latest estimates from the Famine Early Warning System network estimates food insecurity in the region as follows:

¶Ù²¹°ù´Ú³Ü°ùÌý-Ìý3.0 million
South KordofanÌý-Ìý200,000 – 250,000 inÌýSPLM-N areas; 150,000 –200,000 in GoS areas
Blue NileÌý-Ìý100,000 – 150,000 inÌýSPLM-N areas; 100,000 inÌýGoS areas
Red Sea, NorthÌýKordofan, White Nile,Ìýand KassalaÌý-Ìý1 million
AbyeiÌý-Ìý100,000 – 120,000
Total food insecureÌýpopulationÌý-Ìý4.7 million people

See mapÌýhere:

That is not to say that it isn't a striking story. 100,000 people who are forced to live in caves and gather whatever small food they can find is horrific and deplorable. Roughly 200,000 people facing food insecurity in South Kordofan and 4.7 million people in the region at risk deserves attention.

800,000 appears to be a massive overestimation. That more than doubles the number of people estimated to have been displaced by the conflict. Doing so also neglects the other factors contributing to food insecurity. In addition to conflict, the region had poor harvests over the past year, low food stocks and high prices.

It is worth repeating, what has happened in the region is terrible and must be stopped as soon as possible. However, understanding what is happening to the people in the region is of the utmost importance so the proper humanitarian and international responses can take shape. The difference between 800,000 and 200,000 when it comes to malnutrition is very big and it carries a cost. Furthermore, the fact that conflict is not the only problem means that relief and recovery will require aÌývariedÌýset of interventions.

The Sahel is an example of a stalling yet extremely necessary appeal.ÌýEfforts by UNICEF to raise money and awareness about the Sahel show how hard it is to get the right support to provide a proper response. The same applies to the Democratic Republic of Congo, the Horn of Africa and in the Nuba Mountains.

Getting the data as close to correct as possible is crucial, so the request can be extremely targeted, the response can meet the needs on the ground and the expectations of the donors can be met. As much as I hate to admit the last part, it is important. Donors want to see their money put to work in the manner they were told.

Providing the appropriate response to people living in the Nuba Mountains matters most. It is exactly why being precise as possible is so important.

Later this week (I hope), I want to finally take on the question of the power of twitter/social media/slacktavism. There are certainÌýbenefitsÌýto raising awareness, it is why I strongly believe thatÌýDAWNSÌýis necessary, but there are also some serious limitations that should be considered. This seems to be a good example of how easy it is to participate even when the information shared is less certain.

Ìý*It has been pointed out by a few people prior to posting this that vegetarians around the world eat only leaves.
