9. Restoring a disturbed ecosystem to historical conditions may not be valid as ecosystems change.

10. It is increasingly likely that the next century will be characterized by shifts in global weather patterns and climate regimes. precipitation changes

11. Some species can adapt to changes, while other may not.

12. CB 55.2 A key attribute of ecosystems required to ensure resilience and adaptability is that of genetic diversity among and within species.

13. The past is no longer a prescriptive guide for what might happen in the future. precipitation changes

23. Drought in the northern part of Darfur forced nomadic groups to immigrate southwards in search of water and herding ground, which resulted in conflict with sedentary tribes.

26. The extent of the drought forced many Darfurian tribes to change their Nomadic lifestyle and seek settlement in lands considered by other tribes as their Dar or homeland. The decades of drought led to migration of more nomads into Darfur in search of water and grass.

27. The population of Darfur is generally divided into Arabs and non-Arabs. The separation along such lines is probably more based on cultural heritage than on true ethnic separation. Although what is called Arabic tribes may have some Arabic roots, generations of immigration and intermarriage have rendered such separation almost meaningless.

28. Adam Shogar, a commander of the Sudan Liberation Army, the non-Arab rebels at the center of the Darfur conflict, stretched a coal- black arm at Yassine Yousef Abdul Rahman, his copper-skinned, brown-eyed counterpart from an Arab insurgent group, studying him carefully with midnight eyes. "Militia talks could reshape conflict in Darfur" by L. Polgreen The New York Times (April 15, 2007)

29. The struggle in Darfur has often been portrayed as one between Arabs and black Africans, nomads and farmers, with the former bent on slaughtering the latter. But the conflict has never been that simple.

30. There is an essential need to address the root cause of the problem – competition over dwindling natural resources.

31. The nomads and farmers have depended on each other for centuries to survive on some of the world's most forbidding terrain. Farmers allowed herders to traverse their lands, and the herders brought milk and meat. They also transported farm goods to markets, and traded durable goods not usually available in remote farming villages. The farmers bartered those items for vegetables and grain.

32. Solutions to the violence in Darfur must consider the environmental factors behind the conflict.
