In biologically mega-diverse countries that are undergoing rapid human landscape transformation, it is important to understand and model the patterns of land cover change. This problem is particularly acute in Colombia, where lowland forests are being rapidly cleared for cropping and ranching. We apply a conceptual model with a nested set of a priori(More)
BACKGROUND The typical mandate in conservation planning is to identify areas that represent biodiversity targets within the smallest possible area of land or sea, despite the fact that area may be a poor surrogate for the cost of many conservation actions. It is also common for priorities for conservation investment to be identified without regard to the(More)
BACKGROUND Monitoring land change at multiple spatial scales is essential for identifying hotspots of change, and for developing and implementing policies for conserving biodiversity and habitats. In the high diversity country of Colombia, these types of analyses are difficult because there is no consistent wall-to-wall, multi-temporal dataset for land-use(More)
Important transformations are underway in tropical landscapes in Latin America with implications for economic development and climate change. Landscape transformation is driven not only by national policies and markets, but also by global market dynamics associated with an increased role for transnational traders and investors. National and global trends(More)
a r t i c l e i n f o We analyze the economic impacts of policies supporting biodiesel production in Colombia, such as subsidies and mandates for compulsory fuel mixtures. In the major biodiesel source being palm oil, we seek to establish the impact of these policies on oil palm producer incomes, prices and production levels of crude palm oil (CPO) and(More)
• Five dominant trends are occurring in tropical Latin America with implications for land use change: (1) rapid growth of agribusiness, (2) expansion and modernisation of traditional cattle ranching, (3) slow growth of small-scale agriculture, (4) logging in production forest frontiers and (5) resurgence of traditional agro-extractive economies. • These(More)
Understanding the dynamics of natural ecosystems in highly transformed landscapes is key to the design of regional development plans that are more sustainable and otherwise enhance conservation initiatives. We analyzed secondary forest and shrubland dynamics over 30 years (1985–2015) in a densely populated area of the Colombian Andes using satellite and(More)
