<strong>Grassl<strong>and</strong>s</strong> <strong>of</strong> <strong>the</strong> world<br />

It is necessary to improve <strong>the</strong> extension <strong>of</strong> available technologies <strong>and</strong> to<br />

promote <strong>the</strong> training <strong>of</strong> scientists specialized in management <strong>and</strong> conservation<br />

<strong>of</strong> natural grassl<strong>and</strong>s. This discipline does not exist in Uruguay , despite its main<br />

agricultural exports being based on natural grassl<strong>and</strong> outputs.<br />

Scientific knowledge has contributed to better natural grassl<strong>and</strong>s management<br />

practice, which has resulted in biological <strong>and</strong> economic benefits for<br />

farmer communities <strong>and</strong> society in <strong>the</strong> long term, with special care for animal<br />

<strong>and</strong> vegetation biodiversity <strong>and</strong> water conservation for <strong>the</strong> use <strong>of</strong> all living<br />

creatures. Plants <strong>and</strong> domestic animals will continue to provide <strong>the</strong> main food<br />

<strong>and</strong> fibre source <strong>of</strong> <strong>the</strong> world, conditioning our actions <strong>and</strong> behaviour to preserve<br />

natural resources for future generations.<br />

In 1943, Pr<strong>of</strong>essor Bernardo Rosengurtt wrote:<br />

“Let us conserve with infinite care <strong>the</strong> prairie heritage, simultaneously national <strong>and</strong> private, to<br />

transfer it whole to <strong>the</strong> coming generations.”<br />
