Objetivo. Utilizar los sistemas de información geográfica (SIG) como herramienta complementaria para caracterizar la ganadería bovina realizada en la región de la Orinoquia. Materiales y métodos. A través del uso de tecnologías espaciales se recopiló la información concerniente a la orientación ganadera, fisiografía, cobertura vegetal y catastro de la zona de estudio para su posterior análisis a través del software ACCESS de Microsoft. Resultados. En un alto porcentaje de los predios ganaderos ubicados en los cuatro departamentos de la Orinoquía (Casanare:72.7%, Meta:49.5%, Arauca:42% y Vichada:32%) predominan las coberturas de pastos, herbazales y vegetación secundaria, confirmando la expansión en la frontera agropecuaria que es promovida por la actividad ganadera en el país. Conclusiones. El uso de los SIG, permite realizar una mejor planificación y distribución eficiente de los recursos destinados a mejorar el funcionamiento de los sistemas de producción. Por ejemplo, en zonas donde la matriz de coberturas predominante son los pastizales y herbazales, las estrategias en pro de la sostenibilidad pueden enfocarse en la implementación de sistemas silvopastoriles, contrario a lo que pasaría en zonas donde la matriz de coberturas tenga un alto porcentaje de bosques naturales.

The Zapatosa marsh (ciénaga de la Zapatosa) is located in the Department of Cesar in Colombia. In 2018, the muddy complex of Zapatosa was declared a Ramsar wetland, for this reason, it is necessary to develop management strategies for the marsh that allow not only the conservation of the ecosystem. The objective of this work is to use System Dynamics as an evaluation tool for three possible management scenarios of artisanal fishing in the Zapatosa marsh. A qualitative causal diagram and a quantitative Stock and Flow diagrams were designed to describe the dynamics of fish and fishermen populations in the marsh. The initial model setting and parametrization derived from values gathered from different sources of information. The calibration of the model was carried out with reference data on total catch of kilograms of fish and population data from the Department of Cesar. The data obtained through the “Aquaculture and artisanal fisheries survey of the Department of El Cesar” in 2018 were reproduced in the model and then compared with 3 alternative management scenarios. Scenario 1 included strictly applying of the fishing stopover for the species Prochilodus magdalenae and for catfish (Pseudoplatystoma magdaleniatum, Pimelodus blochii y Sorubim cuspicaudus). Scenario 2 considered to apply the same prohibitions, but with a payment to fishermen for the care of the swamp at the time of prohibition. In Scenario 3 the fishermen under fishing stop will receive an income of a legal Colombian minimum monthly salary and will be engaged in practices of ecosystem services. Results showed that in some scenarios the economic situation of the fishermen is unable to meet the monthly family expenses in different periods of the year. On the other hand, there is greater economic stability and fish populations when adopting Scenario 3, but it is difficult to achieve in the short or medium term. Scenario 2 shows little recoveries in fish populations and a higher money availability to the local community than in Scenario 3, in certain months, presenting the best short-term management option. The presented model encourages further simulation scenarios of the Zapatosa Marsh.

Colombian mountain Páramos are considered natural areas with a very important role for human life. Páramos provide, both in mountain and lowland areas, a multitude of ecosystem services which start from vegetation to soil sustainability. The sustainability of Páramos is however impaired by several anthropogenic activities, including agricultural and livestock practices. A system thinking approach was applied in this work to improve the systemic understanding of factors affecting sustainability and resilience of Páramos agro-ecosystems. Interdisciplinary literature evidences were summarized and conceptually analyzed in order to develop causal loop diagrams of Páramo system structures allowing describing the main feedback loops involving (involved in/connecting) the Páramo ecosystem and driving its sustainability. From the causal diagram analysis few insights to maintain the human presence in Páramos arose. The system analysis highlights that human presence in Páramos should be stimulated, avoiding agriculture and livestock activities as the main income source. Particularly, social interactions, education on the Páramos environmental and relevance of agricultural practices to foster ecosystem services and multiple rentable economic activities should be enhanced. The study also includes the role of the government in providing the Páramo inhabitants with payments for ecosystem services and environmental education aimed to boost sustainability. Sustainable Páramo management will apply specific leverages on the system to reach Sustainable Development Goals 6 (water), 8 (economic growth, employment and work), 13 (climate change), and 15 (sustainable use of terrestrial ecosystems) of the Agenda 2030.

The livestock activity is linked to processes with environmental repercussions. Methane (CH4) and nitrous oxide (N2O) are two important greenhouse gases (GHG) emitted into the atmosphere by livestock during the processes of enteric fermentation and excreta management, which contribute to global warming. The objective of this paper was to review the amount of GHG emitted (kg CO2e) per kg of product generated from the main ruminant species (sheep, goats, buffaloes and bovines) used in tropical areas, under grazing conditions. For small ruminants, according to previous researches, emission intensities (EI) for meat was between 25 - 49.5 kg CO2e and for milk was within 5.5 and 11.2 kg CO2e; for buffaloes, EI was among 2.5 – 5.8 kg CO2e / kg FPCM and 21 – 70 kg CO2e / kg CW; for meat cattle, EI was amid 21- 76 kg CO2e; and for dairy cattle, EI was betwixt 2 – 9 kg CO2e. The differences found between the regional averages and the data for the same area of a country, can be due to different factors such as the quality of the pastures, level of intensification of the systems and climatic conditions.

La actividad ganadera contribuye con la emisión de gases de efecto invernadero (EGEI) y el consumo de agua fresca (CA). Por ende, el objetivo de esta investigación fue estimar el efecto de la edad al primer parto (EPP) y los días abiertos (DA) en un bovino doble propósito en pastoreo, trópico bajo colombiano, sobre las EGEI y el CA. Esta estimación se logró integrando 4 metodologías existentes: Dinámica de Sistemas, Large Ruminal Nutrition System, Huella de carbono y Huella hídrica. Durante toda su vida, 91 meses, desde el nacimiento hasta el sacrificio, la vaca produjo 5.879 kg de leche -4 lactancias-, emitió 16.066 kg CO2eq y consumió 12.804.569 L de agua. Al disminuir la EPP en un mes, el CA y las EGEI se redujeron en 123.156 l y 155 kg CO2eq, respectivamente. Cuando se mermaron los DA en 21, las EGEI bajaron 647 kg CO2eq y el CA se redujo en 455.455 L. Parámetros reproductivos como la EPP y los DA tienen una fuerte influencia sobre la dinámica del animal en el hato, afectando su productividad, emisiones de gases de efecto invernadero y consumo de agua.
