In the last decades, growing demand for meat and dairy products has resulted in the continued expansion of the area destined to cattle pastures, often converting pristine ecosystems into extensive pasture systems. This has caused increased deforestation, biodiversity loss and higher greenhouse gas emissions.
However, alternatives to extensive systems exist. Practices such as mixed pastures and silvo-pastoral systems have the potential to sustain biodiversity and ecosystem services whilst generating economic and social benefits. But the substantial implementation costs can act as a barrier to take up. Therefore, tools for systematically evaluating environmental, social, and economic benefits of sustainable practices are needed in assisting the transition and co-designing payment for ecosystem services schemes and other financial support measures.
This webinar will present the science, policy, and evaluation behind sustainable alternatives to extensive cattle ranching through a case study in Valle del Cauca, Colombia. The case study will be introduced in the context of global environmental issues such as climate change and deforestation, presenting the benefits of mixed pastures and silvo-pastoral systems. An interactive tool developed as specific response to the need of informing policy making will be described. The tool is based on an extended cost-benefit analysis from observational information on 300 farms in Valle del Cauca supplemented with secondary data.
