Collapse_ How Societies Choose to Fail or Succeed - Jared Diamond [212]
Thus, there were many reasons why deforestation and other environmental problems began earlier, developed over a longer time, and proceeded further in Haiti than in the Dominican Republic. The reasons involved four of the factors in this book’s five-factor framework: differences in human environmental impacts, in variously friendly policies or unfriendly policies of other countries, and in responses by the societies and their leaders. Of the case studies described in this book, the contrast between Haiti and the Dominican Republic discussed in this chapter, and the contrast between the fates of the Norse and the Inuit in Greenland discussed in Chapter 8, provide the clearest illustrations that a society’s fate lies in its own hands and depends substantially on its own choices.
What about the Dominican Republic’s own environmental problems, and what about the countermeasures that it adopted? To use the terminology that I introduced in Chapter 9, Dominican measures to protect the environment began from the bottom up, shifted to top-down control after 1930, and are now a mixture of both. Exploitation of valuable trees in the Republic increased in the 1860s and 1870s, resulting already then in some local depletion or extinction of valuable tree species. Rates of deforestation increased in the late 19th century due to forest clearance for sugar plantations and other cash crops, then continued to increase in the early 20th century as the demand for wood for railroad ties and for incipient urbanization rose. Soon after 1900 we encounter the first mentions of damage to forest in low-rainfall areas from harvesting wood for fuel, and of contamination of streams by agricultural activities along their banks. The first municipal regulation prohibiting logging and the contamination of streams was passed in 1901.
Bottom-up environmental protection was launched in a serious way between 1919 and 1930 in the area around Santiago, the Republic’s second largest city and the center of its richest and most heavily exploited agricultural area. The lawyer Juan Bautista Pérez Rancier and the physician and surveyor Miguel Canela y Lázaro, struck by the sequence of logging and its associated road network leading to agricultural settlement and watershed damage, lobbied the Santiago Chamber of Commerce to buy land as a forest reserve, and they also sought to raise the necessary funds by public subscription. Success was achieved in 1927, when the Republic’s secretary of agriculture contributed additional government funds to make possible the purchase of the first natural reserve, the Vedado del Yaque. The Yaque River is the country’s largest river, and a vedado is an area of land to which entry is controlled or forbidden.
After 1930, the dictator Trujillo shifted the impetus for environmental management to a top-down approach. His regime expanded the area of the Vedado del Yaque, created other vedados, established in 1934 the first national park, set up a corps of forest guards to enforce protection of forests, suppressed the wasteful use of fire to burn forest in order to clear land for agriculture, and banned the cutting of pine trees without his permission in the area around Constanza in the Central Cordillera. Trujillo undertook these measures in the name of environmental protection, but he was probably motivated more strongly by economic considerations, including his own personal economic advantage. In 1937 his regime commissioned a famous Puerto Rican environmental scientist, Dr. Carlos Chardón, to survey the Dominican Republic’s natural resources (its agricultural, mineral, and forestry potential). In particular, Chardón calculated the commercial logging potential of the Republic’s pine forest, by far the most extensive pine forest in the Caribbean, to be around $40,000,000, a large sum in those days. On the basis of that report, Trujillo himself became involved in logging of pines, and came to own large areas of pine forest and to be the joint owner of the country’s main sawmills. In their
