attracts over 50,000 participants from all over the 

 world. Hardware exhibitors represent a dozen or more 

 countries. 



We also suggest that the United States support 

 adoption of a program, such as that followed in some of 

 the U. S, national laboratories, in which "guest 

 workers" from developing countries would work in 

 laboratories that are conducting research on coal 

 conversion or improved combustion technology 

 (nonproprietary) . Moreover, since coal conversion and 

 fluidized bed technology are considered areas of 

 advanced technology, U.S. universities would also have 

 an interest in this work. A program might be 

 established to provide postdoctoral training on coal 

 utilization applications at existing facilities for 

 developing country scientists and engineers. 



Finally, much of the technology base for coal 

 conversion can be traced to German sources during the 

 1930s and 1940s. These sources are covered in 

 documents now in U.S. possession which are being 

 translated and catalogued by DOE at Oak Ridge. These 

 documents should be made available to other countries. 



A principal constraint in addressing the problem 

 described here is that much of the current technology 

 for coal conversion is covered by proprietary rights. 

 On the other hand, much research and development is now 

 being supported by U.S. government funds and through 

 large consortia such as EPRI and GRI, so that the 

 proprietary issue may be diminishing. 



3. Sustained, Multiple Use of Forest Resources 



In many developing countries, as well as in some 

 parts of the United States, forest resources are being 

 used much faster than they can be regenerated. Forest 

 exploitation is increasing rapidly in these developing 

 countries in response to pressures for export earnings, 

 building materials, fuel, and forage, as well as to 

 make way for habitable lands and farms. Exploitation 

 practices seldom reflect optimal use of forest 

 resources either in the near term or over the lengthy 

 time cycle needed for truly sustainable forest 

 management. For example, many secondary species that 

 could be used for pulp, wallboard, and other 

 applications are simply being destroyed. Further, 

 unsound harvesting practices often degrade the future 

 productivity of the land, destroy wildlife habitats, 

 and invite erosion which destroys adjacent farmland and 

 aggravates the problems of sedimentation and flooding. 

 Finally, insects, disease, and fire continue to take a 

 heavy toll in wooded areas.
