Feeding 9-10 billion people by 2050 and preventing dangerous climate change are two of the greatest challenges facing humanity. Both challenges must be met while reducing the impact of land management on ecosystem services that deliver vital goods and services, and support human health and well-being. Few studies to date have considered the interactions(More)
Soils are subject to varying degrees of direct or indirect human disturbance, constituting a major global change driver. Factoring out natural from direct and indirect human influence is not always straightforward, but some human activities have clear impacts. These include land-use change, land management and land degradation (erosion, compaction, sealing(More)
The agriculture, forestry and other land use (AFOLU) sector is responsible for approximately 25% of anthropogenic GHG emissions mainly from deforestation and agricultural emissions from livestock, soil and nutrient management. Mitigation from the sector is thus extremely important in meeting emission reduction targets. The sector offers a variety of(More)
The use of Simulation for evaluating manufacturing lines has become an accepted means of gathering information and understanding of the lines. One of the primary reasons for this acceptance is the fact that the analysis is now being performed by the people who are experts in the process; those who understand the real world interactions inherent to their(More)
Manufacturing process simulation has long been the domain of mathematicians, operations researchers, and consultants; a relatively small, exclusive group of expert practitioners. Consensus has held that only these individuals can successfully practice the craft of simulation. This thinking persists, even today. There are still many manufacturers who believe(More)
The possibility of using bioenergy as a climate change mitigation measure has sparked a discussion of whether and how bioenergy production contributes to sustainable development. We undertook a systematic review of the scientific literature to illuminate this relationship and found a limited scientific basis for policymaking. Our results indicate that(More)
