Changes to the tropical circulation in the mid-Pliocene and their implications for future climate [PDF]

open access: yesClimate of the Past, 2017
The two components of the tropical overturning circulation, the meridional Hadley circulation (HC) and the zonal Walker circulation (WC), are key to the re-distribution of moisture, heat and mass in the atmosphere. The mid-Pliocene Warm Period (mPWP; ∼ 3.

Climate fluctuations of tropical coupled system: The role of ocean dynamics [PDF]

open access: yes, 2006
The tropical oceans have long been recognized as the most important region for large-scale ocean–atmosphere interactions, giving rise to coupled climate variations on several time scales.

Assessing Haitian Consumers' Willingness to Pay a Premium for Aflatoxin‐Compliant Peanut Butter in the Informal Market

open access: yesAgribusiness, EarlyView.
ABSTRACT Market‐based solutions are increasingly tested to address aflatoxin issues in peanuts in developing countries. Although previous studies have found that Haitian grocery store shoppers are willing to pay a 21% premium for peanut butter with levels of aflatoxin that meet international standards, no information is available for the much larger ...

Arctic sea-ice decline causes intense summer monsoon precipitation events over South Asia under greenhouse warming

open access: yesEnvironmental Research Letters
Arctic sea-ice decline has been accelerating under greenhouse warming. In this study, we investigate the tropical precipitation response to declining Arctic sea-ice using observations and climate model simulations.

Spatiotemporal variability in the O-18-salinity relationship of seawater across the tropical Pacific Ocean [PDF]

open access: yes, 2017
The relationship between salinity and the stable oxygen isotope ratio of seawater (δ18Osw) is of utmost importance to the quantitative reconstruction of past changes in salinity from δ18O values of marine carbonates. This relationship is often considered

Climate‐Smart Dairy Practices: The Role of Practice Clusters in Enhancing the Performance of Dairy Farms in Kenya

open access: yesAgribusiness, EarlyView.
ABSTRACT Climate variability is affecting the productivity, profitability, and resilience of smallholder dairy producers in developing countries. The adoption of climate‐smart (CS) dairy practices has been promoted to mitigate these negative effects. However, while interest in dairy CS practices is growing, empirical evidence on their adoption patterns

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Prioritisation for adaptation in tropical forest ecosystems : Working paper n°44 [PDF]

open access: yes, 2008
Under natural resource ecosystems shared across communities and nations, the distribution among stakeholders of risks and vulnerability to climate change is likely to be uneven on account of the nature of their stakes in the ecosystems, the degree of ...

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.
