"Border Oasis tells how two very different nations developed the delta into an agricultural oasis at enormous environmental cost. Focusing on the years 1940 to 1975 - including the disastrous salinity crisis of the 1960s and 1970s - it combines Mexican, Native American, and U.S. perspectives to demonstrate that the political and diplomatic influences on the delta played as much a part in the region's transformation as did irrigation. Ward reveals how mistrust among political and economic participants has been fueled by conflict between national and local officials on both sides of the border, by Mexican nationalism, and by a mutual recognition that water is the critical ingredient for regional economic development."--BOOK JACKET.
