Definitions of famines are based on three different categories –
these include food supply-based, food consumption-based and
mortality-based definitions. Some definitions of famines are:
Food shortages in a population are caused either by a lack of food or
by difficulties in food distribution; it may be worsened by natural
climate fluctuations and by extreme political conditions related to
oppressive government or warfare.
- Blix – Widespread food shortage leading to significant rise in regional death rates.
- Brown and Eckholm – Sudden, sharp reduction in food supply resulting in widespread hunger.
- Scrimshaw – Sudden collapse in level of food consumption of large numbers of people.
- Ravallion – Unusually high mortality with unusually severe threat to food intake of some segments of a population.
- Cuny – A set of conditions that occurs when large numbers of people
in a region cannot obtain sufficient food, resulting in widespread,
One of the proportionally largest

The stem, black or cereal rusts are caused by the fungus Puccinia graminis and are a significant disease affecting cereal crops. An epidemic of stem rust on wheat caused by race Ug99 is currently spreading across Africa, Asia and most recently into Middle East and is causing major concern due to the large numbers of people dependent on wheat for sustenance. The strain was named after the country where it was identified (Uganda) and the year of its discovery (1999). It spread to Kenya, then Ethiopia, Sudan and Yemen, and is becoming more virulent as it spreads. Scientists are working on breeding strains of wheat that are resistant to UG99. However, wheat is grown in a broad range of environments. This means that breeding programs would have extensive work remaining to get resistance into regionally adapted germplasms even after resistance is identified.
