Abstract (EN):
There is an urgent need to develop new forms of ecosystem management of livestock, in order to encompass economic, social and environmental issues. Livestock farming is often seen as responsible for serious environmental problems such as desertification and intensification of methane emissions. However, when practiced with concern for ecosystems, livestock production can counteract some of these problems and contribute to sustainable development. Adaptive management emerges as a holistic concept of land management that has a capacity to regenerate and provide greater resilience to ecosystems through the use of animals. The implementation of a rotational grazing system provides a greater control over the distribution of animals that, in turn, control biomass in the ecosystem. Knowing that Portugal faces various problems in terms of land management, this paper intends to offer a preliminary approach of how extensive production of animals could contribute to solve some environmental concerns related with livestock production. In order to achieve this goal we use scenarios, concerning two hypothetical situations in two different regions in Portugal, and apply as methodological tool the HOLOS Model Research Program, in order to try to design new ways to deal with livestock production and achieve a sustainable practice.
