Wi<strong>de</strong>spread discontent with foreign control, <strong>the</strong> concentration of <strong>l<strong>and</strong></strong> <strong>in</strong>to large private properties,<strong>and</strong> <strong>the</strong> impoverishment of <strong>the</strong> masses led to unrest, support for opposition lea<strong>de</strong>r Francisco Ma<strong>de</strong>ro, <strong>and</strong><strong>the</strong> Mexican Revolution.5B.3.The Mexican RevolutionFrom 1910 to 1917 <strong>the</strong> Mexican Revolution raged across nor<strong>the</strong>rn Mexico, with lea<strong>de</strong>rs such asZapata, Villa, Carranza <strong>and</strong> Ma<strong>de</strong>ro compet<strong>in</strong>g for power. The Revolution <strong>de</strong>vastated <strong>the</strong> countrysi<strong>de</strong> asrural people ab<strong>and</strong>oned <strong>the</strong>ir crops, government support disappeared, <strong>and</strong> economic <strong>in</strong>stability <strong>in</strong>creased.Despite <strong>the</strong> election of Carranza as presi<strong>de</strong>nt as Presi<strong>de</strong>nt <strong>in</strong> 1917, <strong>and</strong> establishment of a new constitution,it was not until <strong>the</strong> mid-1920s that partial stability returned to Mexico <strong>and</strong> <strong>the</strong> new constitution was fullyimplemented.The Revolutionary constitution had great significance for <strong>l<strong>and</strong></strong> <strong>use</strong> <strong>and</strong> <strong>l<strong>and</strong></strong> <strong>tenure</strong> <strong>in</strong> nor<strong>the</strong>rnMexico. It <strong>in</strong>clu<strong>de</strong>d <strong>the</strong> rejection of foreign ownership of <strong>l<strong>and</strong></strong> <strong>and</strong> resources such as copper <strong>and</strong> oil, <strong>the</strong>restitution of <strong>l<strong>and</strong></strong> to <strong>in</strong>digenous peoples, <strong>the</strong> redistribution of <strong>l<strong>and</strong></strong> <strong>in</strong> <strong>the</strong> form of communal ejidos, <strong>and</strong> <strong>the</strong>expropriation of church property. The breakup of <strong>the</strong> large haciendas had no s<strong>in</strong>gle result for ecosystems.In some cases, <strong>the</strong> ejidos chose to place more cattle or to convert grass<strong>l<strong>and</strong></strong> to crops, <strong>in</strong> o<strong>the</strong>rs <strong>l<strong>and</strong></strong> <strong>use</strong><strong>in</strong>tensity <strong>de</strong>cl<strong>in</strong>ed beca<strong>use</strong> of lack of technical expertise or credit.The full implementation of <strong>l<strong>and</strong></strong> reform began with <strong>the</strong> presi<strong>de</strong>ncy of Lazaro Car<strong>de</strong>nas <strong>in</strong> 1934(figure 5) who also nationalized <strong>the</strong> railroads <strong>and</strong> oil. Dur<strong>in</strong>g his presi<strong>de</strong>ncy vast areas of productivity ofstate owned <strong>in</strong>dustry resulted <strong>in</strong> some expansion of resource extraction.B.4.The Green RevolutionThe 1950s brought several important <strong>change</strong>s of relevance to <strong>l<strong>and</strong></strong> <strong>use</strong> <strong>and</strong> <strong>l<strong>and</strong></strong> <strong>tenure</strong> <strong>in</strong> <strong>the</strong><strong>Chihuahua</strong>n <strong>de</strong>sert. In 1952, labor migration from Mexico to <strong>the</strong> United States was formalized through <strong>the</strong>Bracero guest farm worker program, result<strong>in</strong>g <strong>in</strong> millions of Mexicans travel<strong>in</strong>g to work on US farms over<strong>the</strong> next two <strong>de</strong>ca<strong>de</strong>s. This alternative employment opportunity resulted <strong>in</strong> <strong>the</strong> ab<strong>and</strong>onment of some of <strong>the</strong>more marg<strong>in</strong>al <strong>l<strong>and</strong></strong>s. This trend was exacerbated by <strong>the</strong> onset of <strong>the</strong> 1950s drought. This drought, <strong>the</strong> mostsevere on record <strong>in</strong> <strong>Chihuahua</strong>, resulted <strong>in</strong> wi<strong>de</strong>spread losses of crops <strong>and</strong> livestock as well as long temdamage to natural ecosystems. The Palmer Drought Severity In<strong>de</strong>x show values below –2 for this period<strong>in</strong>dicat<strong>in</strong>g extreme drought conditions (figure 6).However, <strong>the</strong> Bracero program resulted <strong>in</strong> some <strong>in</strong>vestments <strong>in</strong> agriculture <strong>in</strong> Mexico as workerssent remittances back to <strong>the</strong>ir families. It has been estimated that <strong>the</strong>se remittances now provi<strong>de</strong> more than50% of local <strong>in</strong>come <strong>and</strong> <strong>in</strong>vestment <strong>in</strong> many rural communities.At <strong>the</strong> same time, however, <strong>the</strong> Mexican government, with <strong>in</strong>ternational assistance from <strong>the</strong>Rockefeller Foundation, <strong>in</strong>itiated a new agricultural <strong>de</strong>velopment program to <strong>in</strong>crease yields of wheat <strong>and</strong>maize through <strong>the</strong> <strong>use</strong> of improved seeds, irrigation districts of nor<strong>the</strong>rn Mexico, where governmentprograms distributed improved wheat varieties <strong>and</strong> fertilizer. In many cases, yields <strong>in</strong>creased dramatically,<strong>and</strong> Mexican wheat production soared (Figure 7).Some see <strong>the</strong> Green Revolution as a great success (Welha<strong>use</strong>n, 1976; Yates, 1981) po<strong>in</strong>t<strong>in</strong>g tobenefits <strong>in</strong> improved nutrition, farm <strong>in</strong>comes, exports, <strong>and</strong> <strong>in</strong>tensification of <strong>l<strong>and</strong></strong> <strong>use</strong> (ra<strong>the</strong>r thanconversion of un<strong>de</strong>veloped <strong>l<strong>and</strong></strong>).O<strong>the</strong>rs are far more critical, suggest<strong>in</strong>g that unequal access to irrigated <strong>l<strong>and</strong></strong>, credit <strong>and</strong> technologyresulted <strong>in</strong> only a few regions <strong>and</strong> people reap<strong>in</strong>g <strong>the</strong> benefits, <strong>and</strong> that <strong>the</strong> new <strong>in</strong>puts of seeds, water, <strong>and</strong>chemicals damaged ecosystems through loss of diversity, sal<strong>in</strong>ization, <strong>and</strong> pollution (Wright, 1991).S<strong>in</strong>ce 1960 yields of basic crops have <strong>in</strong>creased significantly <strong>in</strong> <strong>the</strong> states of <strong>the</strong> <strong>Chihuahua</strong>n Desert.Wheat acreage <strong>in</strong>creased as a result of <strong>the</strong> Green Revolution, but was followed by a shift from basic gra<strong>in</strong>sto forage <strong>and</strong> vegetable production. Sorghum <strong>and</strong> alfalfa production has been <strong>in</strong>creas<strong>in</strong>g s<strong>in</strong>ce <strong>the</strong> 1960s
