“…It is notable that the groundwater draft for agriculture has decreased over time but the draft for industrial and domestic usage has increased tremendously [63]. This is also in-line with the rapid urbanization trend in the whole of Punjab state where built-up area has increased by 372.27 ha (112.04 %) [65]. The difference in groundwater drawdown matches well to a weak YLS corresponding to RoIs(ch) whereas a strong YLS corresponding to RoIs(h) and RoIs(w).…”

Groundwater depletion is one of the serious geoenvironmental issues causing ground subsidence, which damage buildings, infrastructures and causes loss of life. The quantitative and qualitative evaluation of groundwater variability requires multiple approaches to measure hydraulic head level and geodetic deformation. In this study, we have made efforts to integrate multiple hierarchical space-borne data, including Gravity Recovery and Climate Experiment (GRACE), Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR), geological and hydrological data, to quantify subsidence in Chandigarh city and its surroundings. First, we conducted New-Small BAseline Subsets (NSBAS) and pointwise persistent scatterer (PS) InSAR techniques in parallel, using three-years Sentinel-1 data showing a vertical subsidence up to 120 mm/year around fluvial sediment deposits. Further, correlation analysis of hydraulic/climatic measurements clearly shows the subsidence associated with the groundwater depletion. The pattern of PS points shows the instability of structures associated with the ground subsidence over the central city areas. The monumental architectures designed by Le Corbusier in the northern sectors are outside of the main subsidence area. In the target area, the magnitude of subsidence and surface deformation due to groundwater depletion depending on the subsurface geophysical environment and the anthropogenic activities within the region and surroundings. The results provided a case of monitoring scheme using multiresolution satellite data about the subsidence and associated consequences due to groundwater depletion.

“…Soil fertility has been expressed as the relationship among reactions of organic matter, nutrient ions, and water. Besides, the nature and quality of mineral ores might control the fertility of the soil (Sushanth et al, 2019). Based on the difference in landform, Khadka et al, (2017) collected 81 soil samples (0-20cm) using a soil sampling auger for evaluation of soil fertility in a study area (Tarahara, Sunsari, Nepal).…”

OIL FERTILITY assessment and soil fertility mapping can provide insights for appropriate strategies to select crops suitable for soils and to build a decision making framework to help farmers and improve land management. This study's primary goal was to assess the soil's level of fertility and land suitability for some strategic crops using ASLE software and GIS techniques in some soils at Samanoud District, Gharbia Governorate, Egypt. For this aim, 17 soil samples were randomly distributed over the study area according to locations using GPS. The studied area covers about 166.2 km 2 . In the southern and western regions of the study area, higher clay values were found. The concentrations of N, P and K were evaluated as low or medium based on their availability in the studied area. In the northern regions of the examined area, there was a higher concentration of OM and available P. On the other hand, higher available N levels were seen in the southern regions. Meanwhile, the higher available K values were recorded close to the center of the study region. According to the ASLE program, there are two classes of fertility index data outputs in the area under study: (i) Fair-C3 and (ii) Poor-C4. The soils in the study area were very suitable for growing wheat (S1) and fitted into two classes: very suitable (S1) and suitable (S2) for maize cultivation. In addition, the studied area fitted into three classes including very suitable classes (S1), suitable (S2), and currently unsuitable (N1) for faba bean cultivation. However, the studied area was classified into moderately suitable (S3) and marginally suitable (S4) for rice cultivation. In essence, the appropriate field crops could be categorized according to its suitability as follows: wheat, maize, faba beans, and rice. Such data might help in supporting decision makers for optimum soil management.

A scenario-based analysis of selected best management practices for reduced sediment and nutrient yield in the watershed located in the Shivalik hills, India

In this study, an attempt has been made to evaluate the best management practices (BMPs) in poorly degraded and economically fragile watershed area in Shivalik hills, Northern India. A scenario-based approach has been followed to evaluate the existing BMPs and a few hypothetically implemented BMPs based on SWAT modeling. A regionalization approach was adopted for calibrating the SWAT model for ungauged micro-watersheds within the study area. After successful calibration, soil and water assessment tool (SWAT) model was simulated for several BMPs that are in practice such as Check dams, vegetation and fencing so as to learn about their effectiveness in controlling sediment and nutrient yield. Other hypothetically installed BMPs, such as contouring, terracing, grassed waterways and filter strips were also evaluated in untreated micro and sub-watersheds. The cost–benefit analysis of these hypothetical BMPs revealed that the average reduction in nutrients was maximum for grassed waterways and minimum for terracing. Overall, the scenario-based analysis revealed that conservation practices, in the otherwise degraded watershed, can prove to be beneficial for sustainability of its natural resources.
