Collapse_ How Societies Choose to Fail or Succeed - Jared Diamond [210]
Since the end of the Duvalier dictatorships, Haiti has resumed its former political instability, and its already weak economy has continued to shrink. It still exports coffee, but the amount exported has remained constant while the population has continued to grow. Its human development index, an index based on a combination of human lifespan and education and standard of living, is the lowest in the world outside Africa. After Trujillo’s assassination, the Dominican Republic also remained politically unstable until 1966, including a civil war in 1965 that triggered the arrival again of U.S. marines and the beginning of large-scale Dominican emigration to the U.S. That period of instability ended with the election of Joaquín Balaguer, former president under Trujillo, to the presidency in 1966, helped by ex-Trujillo army officers who carried out a terrorist campaign against the opposing party. Balaguer, a distinctive person whom we shall consider at more length below, continued to dominate Dominican politics for the next 34 years, ruling as president from 1966 to 1978 and again from 1986 until 1996, and exercising much influence even while out of office from 1978 to 1986. His last decisive intervention into Dominican politics, his rescue of the country’s natural reserve system, came in the year 2000 at the age of 94, when he was blind, sick, and two years short of his death.
During those post-Trujillo years from 1961 to the present, the Dominican Republic continued to industrialize and modernize. For a time its export economy depended heavily on sugar, which then yielded in importance to mining, free trade zone industrial exports, and non-sugar agricultural exports, as mentioned earlier in this chapter. Also important to the economies of both the Dominican Republic and Haiti has been the export of people. More than a million Haitians and a million Dominicans now living overseas, especially in the United States, send home earnings that account for a significant fraction of the economies of both countries. The Dominican Republic still rates as a poor country (per-capita income only $2,200 per year), but it exhibits many hallmarks of a growing economy that were obvious during my visit, including a massive construction boom and urban traffic jams.
With that historical background, let’s now return to one of those surprising differences with which this chapter began: why did the political, economic, and ecological histories of these two countries sharing the same island unfold so differently?
Part of the answer involves environmental differences. Hispaniola’s rains come mainly from the east. Hence the Dominican (eastern) part of the island receives more rain and thus supports higher rates of plant growth. Hispaniola’s highest mountains (over 10,000 feet high) are on the Dominican side, and the rivers from those high mountains mainly flow eastwards into the Dominican side. The Dominican side has broad valleys, plains, and plateaus, and much thicker soils; in particular, the Cibao Valley in the north is one of the richest agricultural areas in the world. In contrast, the Haitian side is drier because of that barrier of high mountains blocking rains from the east. Compared to the Dominican Republic, a higher percentage of Haiti’s area is mountainous, the area of flat land good for intensive agriculture is much smaller, there is more limestone terrain, and the soils are thinner and less fertile and have a lower capacity for recovery. Note the paradox: the Haitian side of the island was less well endowed environmentally but developed a rich agricultural economy before the Dominican side. The explanation of this paradox is that Haiti’s burst of agricultural wealth came at the expense of its environmental capital of forests and soils. This lesson—in effect, that an impressive-looking bank account may conceal a negative cash flow—is a theme to which we shall return in the last chapter.
While those environmental differences did contribute to the different economic trajectories of the two countries,
