The purpose of this paper is to describe Fundacion Maquipucuna's community-based entrepreneurship activities. Fundacion Maquipucuna is a unique non-profit organisation in the Choco-Andes region of Ecuador. An ethnographic study and review of the literature is conducted to analyse the cacao, coffee, ecotourism and plastic thatch enterprises of Fundacion Maquipucuna. The enterprises Fundacion Maquipucuna is engaged in support the ongoing sustainability of the biodiverse ecological environment in the Choco-Andes region, which is one of the top five biodiverse hotspots in the world. On a global scale, more emphasis is being placed on promoting sustainability initiatives to preserve the environment. This paper discusses how a litre-government agency Fundacion Maquipucuna is changing from a non-profit to a for-profit structure in order to continue its community engagement projects. This paper integrates the social and community-based entrepreneurship literature to discuss how Fundacion Maquipucuna is engaging in innovative regional development that benefits the whole Choco-Andes community including the large Afro-Ecuadorian population.

At the start of the 21st century the majority of migratory wader (shorebird) populations are faced with serious threats. This commonly results from the continuous destruction of wetlands, their key habitat. Healthy wetlands are highly biodiverse and extremely vulnerable, and as functioning ecosystems particularly important for us humans for a sustained livelihood (artisanal fisheries, small-scale farming) and our well-being (effective water filtering and cleaning systems). In many parts of the world, wetlands have been seen as wastelands, or even as a source of threat (malaria). Many freshwater wetlands have been drained for agricultural use and mudflats have been reclaimed for settlement and urbanization. Wetlands are continuously squeezed by economic development and increasingly used for recreational activities, and their resources are, in general, notoriously overexploited.

Management strategies to reduce the risks to human life and property from wildfire commonly involve burning native vegetation. However, planned burning can conflict with other societal objectives such as human health and biodiversity conservation. These conflicts are likely to intensify as fire regimes change under future climates and as growing human populations encroach farther into fire-prone ecosystems. Decisions about managing fire risks are therefore complex and warrant more sophisticated approaches than are typically used. We applied a multicriteria decision making approach (MCDA) with the potential to improve fire management outcomes to the case of a highly populated, biodiverse, and flammable wildland-urban interface. We considered the effects of 22 planned burning options on 8 objectives: house protection, maximizing water quality, minimizing carbon emissions and impacts on human health, and minimizing declines of 5 distinct species types. The MCDA identified a small number of management options (burning forest adjacent to houses) that performed well for most objectives, but not for one species type (arboreal mammal) or for water quality. Although MCDA made the conflict between objectives explicit, resolution of the problem depended on the weighting assigned to each objective. Additive weighting of criteria traded off the arboreal mammal and water quality objectives for other objectives. Multiplicative weighting identified scenarios that avoided poor outcomes for any objective, which is important for avoiding potentially irreversible biodiversity losses. To distinguish reliably among management options, future work should focus on reducing uncertainty in outcomes across a range of objectives. Considering management actions that have more predictable outcomes than landscape fuel management will be important. We found that, where data were adequate, an MCDA can support decision making in the complex and often conflicted area of fire management.

Global governments have come to recognise and acknowledge that an integrated approach to coastal and marine policy and management in order to govern human actvity is necessary to maintain biodiverse marine ecosystems. This approach to policy and management requires integration rather than simply coordinating policy, planning and management across the coastal and marine interface (Wescott 2012). With just over a third of the global pupulation living along the coastal zone (Millenium Ecosystem Assessment [MA] 2005), it is necessary to consider how natural and political boundaries, economic, social and environmental seascapes integrate concurrently for coastal and marine policy planning and implementation. This is because human activities take place on a continuous gradient across interconnecting catchmenrt, coastal and marine ecosystems, where resource use as diverse as agriculture in coastal marshland and offshore non-renewable energy extraction have to be considered (MA 2003).
