The application of plant growth promoting rhizobacteria (PGPR) to agro-ecosystems is considered to have the potential for improving plant growth in extreme environments featured by water shortage. Herein, we isolated bacterial strains from foxtail millet (Setaria italica L.), a drought-tolerant crop cultivated in semiarid regions in the northeast of China. Four isolates were initially selected ...

I Introduction By linking climatic variations with the fundamental biological requirement of water availability , drought is a primary topic within applied climatology. Drought acts as a unifying climatological approach that provides valuable information for agricultural, ecological, and hydrological applications. While a lack of water is straightforward to comprehend and appreciate, a wide arr...

The ‘new variant famine’ (NVF) hypothesis postulates that the HIV/AIDS pandemic is eroding rural livelihoods and making rural households more vulnerable to drought and other transitory shocks. Despite limited empirical evidence, the NVF hypothesis has become an important part of the conventional wisdom surrounding the relationship between HIV/AIDS and food crises in southern Africa. This study ...

Site-specific studies are required to identify suitable drought indices (DIs) for assessing and predicting drought-related impacts. This study presents a benchmark of eight DIs 19 large-scale climate (CIs) monitor agricultural in Argentina. First, the link between CIs was investigated at departmental-administrative level different temporal scales. Then, effectiveness explaining variability crop...

The chickpea and pigeonpea are protein-rich grain legumes used for human consumption in many countries. Grain yield of these crops is low to moderate in the semi-arid tropics with large variation due to high GxE interaction. In the Indian subcontinent chickpea is grown in the post-rainy winter season on receding soil moisture, and in other countries during the cool and dry post winter or spring...

The Temperature Vegetation Dryness Index (TVDI), a drought monitoring index based on an empirical parameterization of the Land Surface Temperature (LST)–Normalized Difference Vegetation Index (NDVI) space, has been widely implemented in a variety of ecosystems worldwide because it does not depend on ancillary data. However, the simulation of dry/wet edges in the TVDI model can be problematic be...

Drought is one of the most widespread extreme climate events with a potential to alter freshwater availability and related ecosystem services. Given the interconnectedness between freshwater availability and many ecosystem services, including food provisioning, it is important to evaluate the drought implications on freshwater provisioning and food provisioning services. Studies about drought i...

While the medical effects of hydrogen have been broadly analyzed, research into the effects of hydrogen on higher plants has often been of lesser concern. Recent studies on the botanical effects of hydrogen have shown that it is involved in signal transduction pathways of plant hormones and can improve the resistance of plants to stressors, such as drought, salinity, cold and heavy metals. In a...

This paper deals with the question of how responsive farmers in SubSaharan Africa (SSA) are to changes in incentives. Employing Johansen's multivariate cointegration approach, it investigates for ten selected SSA countries the long-run effect of pricing policies, macroeconomic distortions, and certain non-price factors on agricultural production. It turns out that – in those cases where cointeg...
