AbstractThe Amazon rainforest covers roughly 40% of Colombia’s territory and has important global ecological functions. For more than 50 years, an internal war in the country has shaped this region. Peace negotiations between the government and the Revolutionary Armed Forces of Colombia (FARC) initiated in 2012 resulted in a progressive de-escalation of violence and a complete ceasefire in 2016. This study explores the role of different deforestation drivers including armed conflict variables, in explaining deforestation for three periods between 2001 and 2015. Iterative regression analyses were carried out for two spatial extents: the entire Colombian Amazon and a subset area which was most affected by deforestation. The results show that conflict variables have positive relationships with deforestation; yet, they are not among the main variables explaining deforestation. Accessibility and biophysical variables explain more variation. Nevertheless, conflict variables show divergent influence on deforestation depending on the period and scale of analysis. Based on these results, we develop deforestation risk maps to inform the design of forest conservation efforts in the post-conflict period.

And Training

Four workshops and a webinar series were organized, with the aim of building capacity in countries to use Earth Observation Remote Sensing data to monitor forest cover changes and measure emissions reductions for REDD+ results-based payments. Webinars and workshops covered a variety of relevant tools and methods. The initiative was collaboratively organised by a number of Global Forest Observations Initiative (GFOI) partner institutions with funding from the World Bank’s Forest Carbon Partnership Facility (FCPF). The collaborative approach with multiple partners proved to be efficient and was able to reach a large audience, particularly in the case of the webinars. However, the impact in terms of use of tools and training of others after the events was higher for the workshops. In addition, engagement with experts was higher from workshop participants. In terms of efficiency, webinars are significantly cheaper to organize. A hybrid approach might be considered for future initiatives; and, this study of the effectiveness of both in-person and online capacity building can guide the development of future initiatives, something that is particularly pertinent in a COVID-19 era.

Natural And Anthropogenic Factors

China is building forest urban groups through reforestation and afforestation. However, the fast process of urbanization inevitably conflicts with multiple vegetated areas around cities. Hence, it is critical to evaluate the changes in regional vegetation cover and its spatial pattern due to complex natural and anthropogenic factors. Nevertheless, systematic studies to quantify and compare the development of forest urban agglomerations were rarely reported. Based on a remote sensing landcover dataset from 1992 to 2015, this study investigated forest cover changes and the impacts on landscape pattern in several urban groups, and tried to explore their differences between the inland and coastal regions of China. The results showed that over the past 24 years, the forest coverage in the coastal urban agglomerations declined (103 km2/year) while it increased (26 km2/year) in the inland urban agglomerations. There was a certain conflict between forest and cropland for the coastal urban agglomerations where the forest area converted to cropland accounted for 61.9% of the total forest loss. The increase in forests coverage in inland urban agglomerations mainly came from grassland which nearly accounted for 66.47% of the total increase. The landscape diversity has also changed in areas where forests have changed significantly (e.g., Shanghai, Changzhi, and Jincheng).
