The present paper has objective informer the compartment the Weeds Global Invasive in sugar cane crop Saccharum spp. L. (WWGIS) with climate change for Green House Effect. The WWGIS-Worst Weed Global Invasive in Latina American and Caribbean were selection in the I and II curse of weed biology and management in sugarcane, Tabasco sugarcane, 2010-2013. The results of the first course were highlighted by the participants and corroborated in the second. These plants growth in habitats worm and limited water available. The species selections are: 1) ROOEX-Rottboellia exaltata L.f.1782; 2) TRCYN- Digitaria insularis (L.) Fedde, 1904; 3) CYNDA-Cynodon dactylon (L.) Pers. 1805; 4) CYNPL-Cynodon plectostachyus (K. Schum.) Pilg.1907; 5) CHRPO-Chloris elata Desv, 1831; 6) PANPU-Brachiaria mutica (Forssk.) Stapf, 1919; 7) DIGNU-Digitaria nuda Schumach, 1827; 8) DIGAD-Digitaria ciliaris (Retz.) Koeler, 1802; 9) PANMA-Panicum maximum Jacq. 1781; 10) SORHA-Sorghum halepense (L.) Pers. 1805; 11) CYPRO-Cyperus rotundus L. 1753; 12) SYNPO-Syngonium podophyllum Schott, 1851. Ten plants per square meter of each species were height determined. The WWGIS excluded the total organisms in this habitat. With climate changes, there was an increase of 1.03 °C since 1981, alter their biological behavior, with difficult and onerous weed control. With appearance of dwarf plants and produced seeds in winter. After 2005 the biological comportment were graduates altered with normal seeds productions in spring, summer and winter, showed mini plants 0.10-1.30 m high. The behavior of PMIGS is directly linked to the highest minimum winter temperatures. [ABSTRACT FROM AUTHOR]

The objective of this paper is to analyze the advantages of silvopastoral systems in animal feeding due to their potential, their high nutritional value, as well as because of the results obtained in the contribution to the adaptation and mitigation of the climate change. In this sense, the performance of the following important indicators is mentioned: soil care and action of the edaphic biota, management of plant genetic resources with diversity and functionality, pest and disease integrated management and efficient water management, carbon sequestration, effect of the foliage of different species on the metanogenic bacteria in ruminants, the importance of milk composition and its derivatives; in addition, the combination food-energy production, as contribution to the adaptation and mitigation, is analyzed. In farms that integrate agriculture and livestock production, the development of systems including trees in grazing, either for forage or for energy production (forage ligneous plants and biofuel producing plants, due to their importance in the energy subsystem within the supply chain) means a challenge for food selfsufficiency, to regulate the solar energy that has incidence on the soil surface, with a protective effect on the system's temperature, in areas which were previously dedicated only to milk and meat production or to agricultural crops. With these practices, the investment in imports is lower, allowing higher technical productive, economic, social and environmental efficiency to the productive scenarios. [ABSTRACT FROM AUTHOR]
