The Effects of Drought on Crop Yields and Yield Variability in Sahel [PDF]

Drought is widespread in Sahel, and its persistent occurrence has caused substantial damages to the agricultural sector. The severity of drought and the related damages to the agricultural sector are expected to increase due to global warming.

Using SIMGRO for drought analysis – as demonstrated for the Taquari Basin, Brazil [PDF]

, 2010
Tools were developed and tested to quantify space–time development of droughts at the river basin scale. The spatial development of a hydrological drought in river basins brings different challenges to describe drought characteristics, such as: area in a

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

Advanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

Evaluation of Agricultural drought based on NDVI images processing

, 2016
For monitoring agricultural drought, there have quantities of indexes and standards, in this thesis, I try to certify the NDVI value also can apply for monitoring and classifying agricultural drought, except the conventional drought standards.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Farmers' Preferences for Gene Editing Crops and Influencing Factors

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Gene editing (GE) is gaining momentum worldwide, but limited data on UK farmers' preferences hinders our understanding of its potential impact amid deregulation debates. Based on a survey of 200 English arable farmers, we employ a Latent Class Analysis and Multinomial Logit regressions to investigate current preferences for GE crops.

Event-scale investigation on spatiotemporal propagation dynamics between meteorological and agricultural drought

Agricultural Water Management
Meteorological drought can gradually propagate through land surface hydrological processes and further develop into agricultural drought, resulting in clear cascading propagation and time-lag responses between different drought types.

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.
