production in the <strong>arid</strong> l<strong>and</strong>s (Solh et al., 2003). There is a wide availability of technology<br />

developed in Mexico for <strong>arid</strong> l<strong>and</strong> management; however, its integration <strong>to</strong> rangel<strong>and</strong><br />

conservation has been conditioned <strong>to</strong> the scarce Ejidatario’s risk capacity, both, economically<br />

<strong>and</strong> technologically.<br />

Culture for Cattle Production<br />

Nowadays, due <strong>to</strong> market pressure, “cattle culture” posses new components <strong>to</strong> maintain industry<br />

cost-effectiveness as well as <strong>ecosystem</strong> persistence within healthy levels. Herds are comparable<br />

among years <strong>and</strong> among owners through diverse measures for efficiency, resultant <strong>from</strong> the<br />

cattleman ability <strong>and</strong> interest on efficiency improvements, without damage <strong>to</strong> their l<strong>and</strong><br />

productivity, these include: age at first calving, calving intervals, percentages of calving ,<br />

weaning percentages, calve weaning weights, age <strong>to</strong> market, weight <strong>to</strong> several ages, weight <strong>to</strong><br />

market, carcass weight, etc. Those represent important parameters <strong>to</strong> be improved through<br />

good management technology, without grassl<strong>and</strong> detriment condition. Most Ejidatarios do not<br />

utilize those st<strong>and</strong>ard values <strong>to</strong> define herd efficiency. Valuable knowledge for herd efficiency<br />

parameters <strong>and</strong> the way <strong>to</strong> improve them will result in efficient production schemes <strong>and</strong><br />

renewable resources <strong>from</strong> the rangel<strong>and</strong>, mainly, due <strong>to</strong> the fact that supporting rangel<strong>and</strong><br />

condition will be reflected on an increased <strong>and</strong> sustained productivity. Cultural support <strong>to</strong> the<br />

rangel<strong>and</strong>, unknown in Mexico, will result in a better life quality <strong>and</strong> income for l<strong>and</strong> owners. The<br />

constant is <strong>to</strong> remain alert <strong>to</strong> rangel<strong>and</strong> <strong>and</strong> herd efficiency requirements. Programs for cattle<br />

culture promotion among the producers have been developed in Mexico (Roman et al., 2001),<br />

those represent an excellent initiative; however, cattlemen assimilation has been extremely slow,<br />

mainly due <strong>to</strong> the scarce support <strong>to</strong> the program <strong>and</strong> <strong>to</strong> the generated advising dependence<br />

<strong>from</strong> the extensionist. The success of these programs for cattle production <strong>and</strong> culture<br />

promotion at least may result in efficient rangel<strong>and</strong> destruction, if it does not promote<br />

improvement rangel<strong>and</strong> cultural activities, opposed <strong>to</strong> free grazer’s scheme. The best situation<br />

will result of the integration of cattle with rangel<strong>and</strong> culture.<br />

CONCLUSIONS<br />

• Lives<strong>to</strong>ck production on rangel<strong>and</strong> represents the soundest utilization of <strong>arid</strong><br />

<strong>ecosystem</strong>s. The challenge for <strong>arid</strong> rangel<strong>and</strong>s is <strong>to</strong> produce under ecologically friendly<br />

conditions.<br />

• Rangel<strong>and</strong> management schemes must consider drought <strong>and</strong> low winter temperatures<br />

as constant phenomena.<br />

• Common l<strong>and</strong> property systems tie peasants <strong>to</strong> inefficient production systems which<br />

have promoted migration.<br />

• Any l<strong>and</strong> property system resultant <strong>to</strong> PROCEDE program, must establish <strong>and</strong> enforce<br />

rules for grassl<strong>and</strong> use. Traditional support for uncontrolled grazing must be eliminated.<br />

• Rain-fed agriculture <strong>and</strong> stubble grazing is the fastest way <strong>to</strong> desertification.<br />

• Technological development <strong>to</strong> improve successful rain-fed activities with perennial<br />

grasses, supporting <strong>arid</strong> rangel<strong>and</strong>s is a requirement for research development.<br />
