It alludes to the fact that these districts are asphalted, in contrast to the anarchic urban excrescences known as favelas.

The example of Mboro in Senegal, in a horticultural area but also close to phosphate mines, is a good example of this type of interconnection.

The author points out that, notwithstanding this observation, most studies on violence in civil wars have been carried out by urban intellectuals and therefore show an urban bias.

24 Rural environments differ greatly and the idea that they are always poor is a stereotype. Poverty and opulence can co-exist in the countryside, depending on resources and on how wealth is – or is not – redistributed. Some rural areas generate large incomes, for example where they support large-scale cattle ranching, banana plantations, or industrial coffee, palm-oil, or rubber-processing plants. At the same time, within the same region, different types of community – farmers and herdsmen, for example – may live side by side with differing levels of income depending on circumstances.

36 According to the Statutes of the International Red Cross and Red Crescent Movement, adopted by the 25th International Conference of the Red Cross at Geneva in 1986, amended in 1951 and 2006, Art. 5, paras. 3 and 2(d), adopted by an International Conference in which the states took part, ‘The International Committee may take any humanitarian initiative which comes within its role as a specifically neutral and independent institution and intermediary, and may consider any question requiring examination by such an institution’. It must also endeavour to ensure protection of and assistance to victims of what the Statutes call ‘internal strife’ and its ‘direct results’.

39 Under human rights law, the use of lethal force must meet the criterion of strict necessity. International humanitarian law, by contrast, allows such force in a far broader range of circumstances.

43 Launched in 2007 with financial support from the ICRC delegation in Pretoria, this project promotes a culture of tolerance, self-discipline, and personal development through sport. In 2009, 140 schools and 48 youth clubs took part in this initiative.

44 The descriptions of these projects and the lessons learned are based on replies from National Societies to a questionnaire sent to them by the ICRC and the International Federation of Red Cross and Red Crescent Societies as part of the preparation for a workshop on promotion of respect for diversity and non-discrimination, held in Nairobi in 2009.

45 These groups tend to stigmatize the behaviour of young people and call for stronger measures (‘a firm hand’), sometimes for political ends (for example, to attract votes before an election).
