The purpose of the United Nations Challenge Badges is to raise awareness, educate and, most of all, motivate young people to change their behaviour and be active agents of change in their local communities. Challenge Badges are appropriate for use with school classes and youth groups, and are endorsed by WAGGGS and WOSM. They include a wide range of activities and ideas that can easily be adapted by teachers or leaders.

Historically, land improvement schemes were based on encouraging, through financial incentives, land users to adopt specific soil management and conservation measures. Insufficient attention was paid to the constraints faced by farmers or to the policy, biophysical and socio-economic environment. In many cases such approaches have failed in restoring the natural resources and in increasing productivity in sustainable manner. For too long farmers have been the passive recipients of externally derived research and extension recommendations for soil management and conservation.

Нормально функционирующие почвы играют ключевую роль в снабжении чистой водой и в обеспечении устойчивости к наводнениям и засухам. Благодаря своей водопроницаемости почва задерживает содержащиеся в воде загрязняющие вещества и препятствует их выщелачиванию в грунтовые воды. Кроме того, почва удерживает и сохраняет воду, обеспечивая ее доступность для сельскохозяйственных культур и, тем самым, сводит к минимуму испарение с поверхности и максимально повышает эффективность и производительность водопользования.

The impacts of natural disasters such as hurricanes, floods, earthquakes and tsunamis have been increasing steadily since the 1950’s, particularly for developing countries. According to a World Bank external evaluation report “natural disasters destroyed US$652 billion in property worldwide in the 1990s alone – an amount 15 times higher in real terms compared to the 1950s. Approximately 2.6 billion people were affected by natural disasters over the past ten years, compared to 1.6 billion in the previous decade.
