Undivided colonial India experienced an accelerated rate of economic change in the nineteenth and twentieth centuries. Official policies and funds combined with private entrepreneurial energies and investment to intensify India's linkages with the world market in trade, industry, agriculture, and natural resource extraction. Slow, but in the long term steady, population expansion accompanied this trend. After 1947, economic development accelerated under five-year plans in India, Pakistan, and Bangladesh, and transformed the earlier colonial economy. Population figures have similarly shot up since partition and independence. These two linked trends have accompanied steadily intensifying human intervention in the natural environment of the subcontinent over the same time. One effect, among others, has been dramatic alteration in land use and vegetation cover. Comparing Francis Buchanan's early nineteenth-century descriptions of the countryside in both north and south India with the appearance of these areas today suggests just how sweeping these changes have been. The landscape of today in virtually every Indian district is very different from that seen two hundred or even hundred years ago.
