Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Drought frequency analysis for California from observed, synthetic, and proxy data [PDF]

open access: yes, 1993
Drought frequency analysis can be performed with statistical techniques developed for determining recurrence intervals for extreme precipitation and flood events (Linsley et al 1992).

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

open access: yesAmerican 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.

Evolutionary rescue during extreme drought

open access: yes
Abstract Populations declining due to climate change may need to evolve to persist. While evolutionary rescue has been demonstrated in theory and the lab, its relevance to natural populations facing climate change remains unknown. Here we link rapid evolution and population dynamics in scarlet monkeyflower, Mimulus cardinalis, during an ...

Agricultural drought in the Claromecó river basin, Buenos Aires province, Argentina [PDF]

open access: yes, 2008
The dry and wet periods affecting the Claromecó Creek Basin in the south of the Province of Buenos Aires were analysed applying Palmer’s Model. Palmer’s Drought Severity Index was calculated regionally for five towns for the 1904-1999 period.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Dynamics of Extreme Drought and Extreme Wet in Indonesia: Analysis of Frequency, Trends, and Spatial Distribution 1995–2024

open access: yesJIF (Jurnal Ilmu Fisika)
The climatological pattern of rainfall and the occurrence of extreme drought and extreme wet in Indonesia are influenced by monsoon dynamics, topography, and Sea Surface Temperature Anomalies (SSTA) in the Pacific and Indian Oceans.

Effects of single and repeated drought on soil microarthropods in a semi-arid ecosystem depend more on timing and duration than drought severity.

open access: yesPLoS ONE, 2019
Soil moisture is one of the most important factors affecting soil biota. In arid and semi-arid ecosystems, soil mesofauna is adapted to temporary drought events, but, until now, we have had a limited understanding of the impacts of the different ...
