The ridge furrow (RF) rainwater harvesting system is an efficient way to enhance rainwater accessibility for crops and increase winter wheat productivity in semi-arid regions. However, the RF system has not been promoted widely in the semi-arid regions, which primarily exist in remote hilly areas. To exploit its efficiency on a large-scale, the RF system needs to be tested at different amounts ...

Understanding the impact of water availability on vegetation growth in context climate change is crucial for assessing resilience to environmental shifts. In this study, relationship between and was studied using a variety indicators. The Normalized Difference Vegetation Index (NDVI), Enhanced (EVI), Solar-Induced Chlorophyll Fluorescence (SIF) were utilized as indicators, while standardized pr...

[1] Natural archives of oxygen isotopes in precipitation may be used to study changes in the hydrological cycle in the tropics, but their interpretation is not straightforward. We studied to which degree tree rings of Mimosa acantholoba from southern Mexico record variation in isotopic composition of precipitation and which climatic processes influence oxygen isotopes in tree rings (δ18Otr). In...

abstract- efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. this research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (wp) with different water management scenarios at farm level at ...

The climate parameters annual rainfall and average mean temperature are investigated from 2000 to 2019 for Kut, Hilla Iskandaryia. Evidence of change is noticed by decreasing the relative humidity with an increase in temperature. water balance has been calculated. Due high temperature, increased evaporation, low precipitation rates, there was a large deficit. total surplus Kut area 32.86 mm Nov...

In recent decades, water scarcity is a significant constraint for socioeconomic development and threatens livelihood in an agriculture-based developing country like Pakistan. The crisis the projected to exacerbate coming years, especially southern parts. This dire situation calls investigation of major droughts, associated scarcity, changes teleconnection patterns over Southern Moderate low Sou...

introduction: drought is a natural and recurrent feature of climate. the characterizations of it may change under the effect of climate change in future periods. during the last few decades a number of different indices have been developed to quantify drought probabilities. droughts are caused by disruptions to an expected precipitation pattern and can be intensified by unusually high temperatu...
