Smallholder farmers are vulnerable to environmental, climate and weather-related stress, including climate change. There is an increase in understanding of the benefits of agroforestry systems both at farm and landscape scales, and that incorporating trees on farms through agroforestry systems has emerged as having the potential to enhance the resilience of smallholders to current and future climate risks including future climate change. Drawing on global examples with a focus on African case studies, this paper demonstrates the versatile roles of trees and agroforestry in reducing smallholder's exposure to climate-related risks. It goes on to identify challenges in the promotion and adoption of agroforestry at the farm and landscape levels as a climate change adaptation strategy. The paper highlights areas for further research, policy and dissemination efforts, and identifies entry points for agroforestry adoption. © 2013 Rodel D Lasco.

Understanding the environmental effects of alternative fuel production is critical to characterizing the sustainability of energy resources to inform policy and regulatory decisions. The magnitudes of these environmental effects vary according to the intensity and scale of fuel production along each step of the supply chain. We compare the spatial extent and temporal duration of ethanol and gasoline production processes and environmental effects based on a literature review and then synthesize the scale differences on space-time diagrams. Comprehensive assessment of any fuel-production system is a moving target, and our analysis shows that decisions regarding the selection of spatial and temporal boundaries of analysis have tremendous influences on the comparisons. Effects that strongly differentiate gasoline and ethanol-supply chains in terms of scale are associated with when and where energy resources are formed and how they are extracted. Although both gasoline and ethanol production may result in negative environmental effects, this study indicates that ethanol production traced through a supply chain may impact less area and result in more easily reversed effects of a shorter duration than gasoline production. © 2012 Springer Science+Business Media New York (outside the USA).

Climate model development, testing, and analysis involve running the model extensively to tune the subgrid- scale parameters that provide closure to the system. This process demands substantial time and computational resources even for typical spatial resolutions and becomes in feasibly expensive for high-resolution studies. This paper presents alternative, computationally feasible methods to emulate the simulations within acceptable error bounds. This strategy can be easily implemented to obtain an ensemble of model runs. The paper outlines three approximation strategies: (1) interpolation with Lagrange basis functions, (2) least-squares (LS) approximation, and (3) interpolation with radial basis functions. As a proof of concept, a suite of relevant physical quantities are evaluated at unknown grid points of parameters, space, and time. The values obtained by emulation are compared against the simulated values to check the feasibility of the method. The advantages and shortcomings of the above-mentioned approximation schemes are discussed, including the savings of time and computational resources. © 2014 Taylor & Francis.

We are entering the Anthropocene. So large is our impact on the planet that Earth scientists suggest our presence will show up in the geologic record far into the future. The global ecological changes we are creating pose a threat to health not only from climate change but from pollution and ecotoxicity, ocean acidification, resource depletion and the loss of biodiversity that threatens a sixth Great Extinction. These health threats will impose an added burden on the healthcare system, while the ecological changes will force it to adapt to the new realities. The healthcare system contributes to these changes. It is an energy and resource-intensive part of society that also produces large volumes of solid and liquid wastes and air pollutants, some of them quite toxic; the system has a large ecological footprint; yet, at the same time, the system has an ethical duty to do no harm, and thus should be a leader in the transition to a more ecologically sustainable and healthier future.
