How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

The Late Triassic-Early Jurassic active continental margin of western North America in northeastern Mexico [PDF]

Geofísica Internacional, 1998
Exposures of Triassic-Jurassic volcanic sequences in northeastern Mexico suggest that they developed along an active continental margin. Other sequences in support of such a tectonic environment are exposed in Durango, Zacatecas, San Luis Potosí, Nuevo ...

Food insecurity and unemployment among immigrants in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Seismogenic Fault Reactivation in Western Central Africa: Insights From Regional Stress Analysis

Geochemistry, Geophysics, Geosystems, 2022
The onshore continental margins of western Central Africa have been hosting potentially damaging earthquake events for decades; yet, the links between the seismicity, the contemporary stress field, and pre‐existing faults are not well understood.

Choice experiments on land managers' participation in environmental programs: A systematic review and meta‐analysis of estimate validity

American Journal of Agricultural Economics, EarlyView.
Abstract Discrete choice experiments are increasingly being used to estimate land managers' willingness to accept participation in incentive‐based environmental programs. This is a specific application of discrete choice experiments: the estimation of willingness to accept for a private good (program participation) where respondents have to make trade ...

Landside hazard on the Norwegian continental margin

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
Numerous landslides are located on the passive margin of Norway. According to the landslides number and the extent of their detachment zones, the margin can be divided into three segments (from south to north) — Scandinavian, Barents Sea and Svalbard ...

Slab Pull Driven South China Sea Opening Implies a Mesozoic Proto South China Sea

Geophysical Research Letters, 2023
Most paleo‐reconstruction models agree that the South China Sea (SCS) opens within a continental domain located at the trailing edge of the subducting plate of a vanished ocean named Proto South China Sea (PSCS).

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]

, 2004
The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...
