Expert Forecasts for 2020

Nations in the scientifically developing group commonly face many of the same problems as those in the scientifically lagging group. For example, in most of these countries, a significant percentage of the population is rural, with many people living at or below the poverty line. Nations in the scientifically proficient group face a dynamic mix of problems. Promoting economic development and international commerce is often a top priority for countries with this level of S&T capacity but for very diverse reasons. The populations of China and India, for example, are quite large and continually growing. These countries urgently need to feed their many people, create jobs, and sustain wide-scale economic development. Yet while Poland and Russia have much smaller populations, economic growth is no less a concern. In the decade following the dissolution of the Soviet Union, Russia has encountered considerable economic difficulties. Although its population is shrinking in real terms, unemployment is high. The exodus of Russian scientists, engineers, and other professionals beginning in the 1990s has weakened the country’s institutional and human capacity in science, health, and administra-tion. Poland, as a relatively recent member of the European Union, is in a very different situation: It needs to bring its economy in line with EU standards. In China and India, a significant fraction of the population is rural and impoverished. In terms of improving public health, the same applications that the developing countries have the S&T capacity to acquire toward this end—cheap solar energy, rural wireless communications, GM crops, filters and catalysts, cheap autonomous housing, rapid bioassays, and green manufacturing—could help the proficient nations as well. In addition, these countries have the S&T capacity to acquire targeted drug delivery, which is likely to eventually become such a widespread application that it will enable cancers and other diseases to be treated on site in remote areas, with significant benefits to public health. Similarly, they will be able to acquire the same applications as the developing countries to reduce the use of resources and improve environmental health: cheap solar energy, rural wireless communications, GM crops, filters and catalysts, green manufacturing, and hybrid vehicles. Global diffusion of a technology application does not mean universal diffusion: Not every nation in the world will be able to implement, or even acquire, all technology applications by 2020. The level of direct S&T capacity may be markedly different from one country to another. Within different geographical regions, countries also have considerable differences that play into their ability. These differences may include variations in physical size, natural conditions (e.g., climate), and location (e.g., proximity to oceans and water). The size of the population and demographics (e.g., birthrate) may vary dramatically between countries in a single region. Countries may have very different types of government, economic systems, and levels of economic development.
