Constructing futures, enhancing solutions: Stakeholder-driven scenario development and system modeling for climate-change challenges

Finding effective and practical solutions to climate change challenges in food-energy-water systems requires the integration of experts in local/regional social and biophysical systems, and these are commonly local community members. In the Magic Valley, Idaho we investigated the tensions between water used for energy and to irrigate cropland for food production, as well as, strategies for protecting water quantity and quality. Incorporating stakeholders with long-standing expertise allows the development of solutions to these challenges that are locally and regionally practical and consistent with the values of the social system into which they are incorporated. We describe a stakeholder-driven process used in a case study in the Magic Valley that incorporated local experts to develop plausible future scenarios, identify drivers of change, vet impact and hydrological modeling and map areas of change. The process described allowed stakeholders to envision alternative futures in their region, leading to development of enhanced context and place-based solutions and an anticipated time line for adoption of those solutions. The solutions developed by the stakeholders have been applied across many geographic areas. The described process can also be applied across a broad range of geographic levels. Most importantly, stakeholders should be involved in anticipating solutions and solution timing to the differing challenges posed by each scenario

The differential hormonal milieu of morning versus evening, may have an impact on muscle hypertrophic potential

Substantial gains in muscle strength and hypertrophy are clearly associated with the routine performance of resistance training. What is less evident is the optimal timing of the resistance training stimulus to elicit these significant functional and structural skeletal muscle changes. Therefore, this investigation determined the impact of a single bout of resistance training performed either in the morning or evening upon acute anabolic signalling (insulin-like growth factor-binding protein-3 (IGFBP-3), myogenic index and differentiation) and catabolic processes (cortisol). Twenty-four male participants (age 21.4±1.9yrs, mass 83.7±13.7kg) with no sustained resistance training experience were allocated to a resistance exercise group (REP). Sixteen of the 24 participants were randomly selected to perform an additional non-exercising control group (CP) protocol. REP performed two bouts of resistance exercise (80% 1RM) in the morning (AM: 0800 hrs) and evening (PM: 1800 hrs), with the sessions separated by a minimum of 72 hours. Venous blood was collected immediately prior to, and 5 min after, each resistance exercise and control sessions. Serum cortisol and IGFBP-3 levels, myogenic index, myotube width, were determined at each sampling period. All data are reported as mean ± SEM, statistical significance was set at P≤0.05. As expected a significant reduction in evening cortisol concentration was observed at pre (AM: 98.4±10.5, PM: 49.8±4.4 ng/ml, P0.05). Timing of resistance training regimen in the evening appears to augment some markers of hypertrophic potential, with elevated IGFBP-3, suppressed cortisol and a superior cellular environment. Further investigation, to further elucidate the time course of peak anabolic signalling in morning vs evening training conditions, are timely
