Compositional diversity of rehabilitated tropical lands supports multiple ecosystem services and buffers uncertainties

چکیده
High landscape diversity is assumed to increase the number and level of ecosystem services. However, the interactions between ecosystem service provision, disturbance and landscape composition are poorly understood. Here we present a novel approach to include uncertainty in the optimization of land allocation for improving the provision of multiple ecosystem services. We refer to the rehabilitation of abandoned agricultural lands in Ecuador including two types of both afforestation and pasture rehabilitation, together with a succession option. Our results show that high compositional landscape diversity supports multiple ecosystem services (multifunction effect). This implicitly provides a buffer against uncertainty. Our work shows that active integration of uncertainty is only important when optimizing single or highly correlated ecosystem services and that the multifunction effect on landscape diversity is stronger than the uncertainty effect. This is an important insight to support a land-use planning based on ecosystem services.

Perennial grasslands enhance biodiversity and multiple ecosystem services in bioenergy landscapes.
Agriculture is being challenged to provide food, and increasingly fuel, for an expanding global population. Producing bioenergy crops on marginal lands--farmland suboptimal for food crops--could help meet energy goals while minimizing competition with food production. However, the ecological costs and benefits of growing bioenergy feedstocks--primarily annual grain crops--on marginal lands have...
متن کاملThe Role of Herbivory in Structuring Tropical Seagrass Ecosystem Service Delivery
Seagrass meadows support key ecosystem services, via provision of food directly for herbivores, and indirectly to their predators. The importance of herbivores in seagrass meadows has been well-documented, but the links between food webs and ecosystem services in seagrass meadows have not previously been made explicit. Herbivores interact with ecosystem services - including carbon sequestration...
متن کاملFrom Target to Implementation: Perspectives for the International Governance of Forest Landscape Restoration
Continuing depletion of forest resources, particularly in tropical developing countries, has turned vast areas of intact ecosystems into urbanized and agricultural lands. The degree of degradation varies, but in most cases, the ecosystem functions and the ability to provide a variety of ecosystem services are severely impaired. In addition to many other challenges, successful forest restoration...
متن کاملTropical forest recovery and restoration
R a week goes by without a news report sounding the alarm of the continued destruction of tropical forests and the concomitant loss of biodiversity and ecosystem services, such as water retention, erosion control and carbon storage. Much of tropical deforestation, particularly in Latin America, is a result of land clearing for pasture and other agricultural uses1. Increasingly, these lands are ...
متن کاملRestoring lepidopteran diversity in a tropical dry forest: relative importance of restoration treatment, tree identity and predator pressure
Tropical dry forests (TDFs) have been widely transformed by human activities worldwide and the ecosystem services they provide are diminishing. There has been an urgent call for conservation and restoration of the degraded lands previously occupied by TDFs. Restoration experiences aim to recover species diversity and ecological functions. Different restoration strategies have been used to maxim...
