426 THE FUTURE OF ARID LANDS 
11. Manage vegetation and livestock to balance forage with 
livestock requirements. 
12. Explore new patterns of land use and management. 
What are the economic possibilities in the development and utili- 
zation of arid land plants and animals? 
Excellent with basic program of research, teaching, and exten- 
sion. 
1. Increase in knowledge and understanding of basic principles 
involved. 
Intensification of education and extension programs: (a) 
translating knowledge at hand into action, (4) expansion of dem- 
onstration areas of improved practices, (c) cooperation of public 
and private agencies. 
3. Modify land tenure and credit systems to meet needs of a 
sound program of production and use. 
4. Establish objectives and needs of programs on a national 
basis. 
5. Promote culture of food trees: olive, almond, carob, pis- 
tachio, fig, and date. 
6. Regional understanding and agreements on management 
and use. 
7. Agreements on relative values of competitive uses of water. 
8. Classify and control livestock for more efficient land, use. 
What are the possibilities of maintaining larger human popula- 
tions in arid areas? 
1. Possibilities will vary according to present population num- 
bers, resources, and possibilities for development. Some areas al- 
ready have population and resources out of balance. | 
2. Some areas are favorable for expansion but improved stand- 
a are more important as a first step. 
3. Demineralization of water for human and livestock watering 
will permit more efficient utilization of vegetation in some areas. 
4. Stabilize population through integration of social and eco- 
nomic factors.
