ISSUES Regardless of whether a number of institutions close, the possibility of declining enrollments makes faculty job security uncertain. As enrollments be- come stable or decline, and as institutions are faced with the necessity to curtail or terminate programs, these changes inevitably will have an impact on college and university faculty. As a result of large faculty expansions of the 19603, today

CRS-3 Other changes also can be predicted in the characteristics of higher educa- tion enrollments. Traditionally, enrollment trends in higher education have followed the trends of the 18- to 24-year old population. However, the 1980s already present a movement away from this direct relationship as higher educa- tion institutions attempt to attract more older students. Census reports indi- cate

CRS-23 There is no doubt that sufficiently high inputs of acid can acidify forest soils. It is not easy to define those "sufficiently high inputs," however, since one of the most crucial processes, soil weathering, cannot be easily quantified. Weathering in this context refers to the replenishment of available, or more precisely, exchangeable base cations from non-exchangeable soil reserves. It is a crucial process because it actually determines the degree to which soils can be acidified by acid deposition. That is, if acid deposition-accelerated leaching exceeds weathering, soils will acidify and if weathering keeps pace with leaching, no acidification will occur. .. - we - The relationship between acid deposition, mineral weathering, leaching, and the soil neutralizing capacity are not completely understood. Because of the lack of data, there is disagreement about whether acidification of the environment is occuring from acidic deposition, the rate at which it may be occurring, to what extent lakes and forests are buffered by the a watershed soil characteristics, and the subsequent long-term effects of an acid if ied environment . Natural Soil Acidification Process.‘ One of the most polarized discussions on effects of acidic deposition is whether soil is acidifying only or primarily through natural processes. The National Acid Precipitation Assessment Program states that a "The deposition of acidic substances on soils may be making only a minor contribution to the natural soil acidification process." But Dr. Bernabo, in response to questions asked at the hearing, states with respect to soils and forests, "Available evidence seems to support combined pollutent effcts on foliage, although soil-mediated processes cannot be ruled out at this time.”

CRS-21 Terrestrial Environment Soils Soils link the aquatic and terrestrial environments. As stated in the preceding section on the aquatic environment, acidification vulnera- lwility of the ecosystem is usually related to overlying granitic soils Jith minimal natural neutralizing capacity. Managed Soils and Crops. There is general consensus that managed, agricultural soils are not very susceptible to detrimental effects from acid deposition. As Dr. Richard Klein and Hubert Vogelmann of the University of Vermont explain, "[s]uch lands are regularly fertilized and their acidity adjusted." Therefore, other pollutants may have more df an effect on crops than acidic deposition, either directly or through soiiémediated processes.‘ As Dr. Bernabo states: ; , Scientists have found little conclusive evidence for major direct effects of acid precipitation on vegetation at current deposition levels. The direct effects on crops appear less significant than those related to other air pollutants such as ozone. . . . Although future research is required to increase the certainty of our conclusions, concern over crop losses has decreased substantially. i Unmanaged Soils. Both positive and negative effecfs have been observed from the input of sulfur and nitrogen into the soil. The positive effects are exhibited because nitrogen and sulfur, the major components iof acidic deposition, are also primary plant nutrients, and sometimes act as a fertilizer. Negative effects are hotly debated. Dr. Bernabo states that "[f]or un- managed soils, recent studies on natural soils acidity production have decreased concerns over soil pH changes."

. the conventional wisdom regarding normal rainfall is that it has an acidity of about 5.6 on the pH scale. (On the pH scale of 0 to 14, pure water has a pH of 7.0. The lower the number, the more acid a substance; for example, lemon juice and vinegar have pHs of between 2 and 3. Since the pH scale is logarithmic, a pH of 6 is l0 times more acid than pure water, a pH of S is 100 times more acidic, a pH of 4 is 1000

CRS-iv enactment of control legislation. But the majority of the witnesses felt that the benefits that might accrue from reducing emisions were much less certain than the costs and potentially adverse consequence of controls, so the majority of witnesses advocated further research before taking action on controls. As stated by Dr. Bernabo, "The understanding of mechanisms in the acid rain issue is vital to avoid spending large amounts of money, dislocating industry an — and workers, etc. without a reasonably firm foundation that the action will produce the desired benefits." 8. Many witnesses who opposed enacting control legislation before further research results were available nevertheless comented on certain principles that they felt any such legislation should contain. Among the principles mentioned were (a) that the polluter should pay--as opposed to cost-sharing; (b) that a balance between costs and benefits should be sought -by allowing sources to choose how to achieve any required emission reductions rather than by mandating technology; (c) that emissions should not be capped; and (d) that the use of coal should not be discouraged. 9. Research needs were noted by many witnesses, some of whom made general recommendations while others outlined detailed research proposals. The cited research needs fell into several categories, including: (a) research on the transport and transformation of precursor pollutants, sulfur dioxide and nitro~ gen oxides; (b) research on the effects of acid precipitation; (c) research on ecological phenomena that might be affected by acid precipitation, especially forest decline; (d) research on precipitation, lake, stream, and soil chem- istry; (e) monitoring; and (f) research, development, and demonstration of new°technologies for controling emissions.
