Опубликована: Март 10, 2025

In arid regions, irrigated agriculture is mainly dependent on groundwater. Pakistan, 73% of agricultural land directly or indirectly through Punjab (Pakistan), 1.2 million private tube wells are operating, extracting 90% the country’s Most these poorly designed due to improper site investigations and poor estimations aquifer’s hydraulic parameters. As a result, most become dry, causing considerable financial losses farmers. Hence, optimizing well-designed parameters proper soil essential. This research aims develop statistical model for estimating conductivity on-site investigation: five sites were selected in Multan seven samples collected at each location from 3, 6, 9,12,15,18, 21 m depth. For conductivity, texture, porosity, laboratory tests carried out. Finally, was developed using hydrological such as average grain size distribution (D50), uniformity coefficient (U), porosity (n). Statistically computed verified with experimentally measured empirically derived conductivity. showed closer agreement than conductivity: root mean square error (RMSE), correlation (Cc), absolute (MAE) are, respectively, equal 0.013, 0.93, 0.011.

Detection of heavy metals using atomic absorption and emission spectroscopy in drinking water of Faisalabad, Pakistan: microbial safety and quality status assessment

Toxin Reviews, Год журнала: 2023, Номер 43(1), С. 1 - 17

Опубликована: Окт. 30, 2023

Synthetic dyes from textile industries are designated as hazardous waste since they release heavy metals and dangerous contaminants in water that harm the environment human health. The current study was aimed at investigating (Cd, Cu, Pb, Ni, Zn, Cr, Mn) drinking seven regions of Faisalabad, Pakistan, through atomic absorption spectroscopy (AAS) optical emission (OES). physicochemical quality 86.36% samples met WHO standards targeted regions, while 13.64% failed to meet criteria. index (WQI) selected calculated by integrating 11 parameters, results indicated fair quality, whereas Madina, Jinnah, Lyallpur Town showed poor with contamination Mn > Ni Pb. order for groundwater Cu Zn Cr Pb Cd. total plate count (TPC) coliform (TCC) were found within permissible range guidelines. Hence, consuming research may not present major health risks due ingested metal toxicity; however, levels Mn, might pose risks.

Carbon border adjustment mechanism challenges and implications: The case of Visegrád countries

Heliyon, Год журнала: 2024, Номер 10(10), С. e30976 - e30976

Stricter climate policies across the European Union are enhancing phenomenon of free riding by nonacting countries, which translates into carbon leakage and loss competitiveness. This paper investigates trade, economic environmental implications future implementation a border adjustment mechanism (CBAM) in Visegrád countries as EU member states. We exploit trade data to estimate price income elasticities for emission-intensive trade-exposed (EITE) goods imported from non-EU trading partners countries. Based on these estimates, combined with average intensity EU's proposed list EITE goods, we simulate six different configurations restrictiveness CBAM imposed imports find that high elasticity tend significantly decrease import demand under CBAM. Moreover, will yield relatively small adverse impact growth total emissions

The Impacts of Land Use Changes on Water Yield and Water Conservation Services in Zhangjiakou, Beijing’s Upstream Watershed, China

Sustainability, Год журнала: 2023, Номер 15(14), С. 11077 - 11077

Опубликована: Июль 15, 2023

The Water Conservation Functional Zone and Ecological Environmental Supporting (the Capital Two Zones in China), Zhangjiakou (ZJK) City, situated China, has played a key role mitigating water scarcity pressure on Beijing via delivering sustainable high-quality yield, as well conservation services aimed at maintaining the ecological functions of Zones. However, changing mechanism for both yield instigated by combined impacts human activities climate change remains poorly understood. In this study, we used Integrated Valuation Ecosystem Services Trade-offs Tools (InVEST) model to analyze changes services, revealing different land use scenarios. results showed significant forest impervious area increment, while surface decreased sharply from 1990 2020, with obvious urbanization expansion ZJK during period. Average annual 2020 were recorded 48.98 mm 2.35 mm, respectively. Precipitation emerged primary driver service changes, south generally exhibited higher than north ZJK. Results also indicate that grassland had highest an average 56.60 followed (55.66 mm) shrub (55.07 mm). Further, value (3.73 mm), (2.56 (2.37 return cropland scenario most substantial decrease yield. Findings suggest precipitation direct impact amount atmospheric input, alteration contributes regional-scale water.

Egypt has recently inaugurated a mega development project aiming to alleviate the overpopulation along Nile River and meet looming food gap. Toshka is promising area where groundwater-dependent activities are being expanded adjacent Lake Nasser. Thus, it of utmost importance provide sustainable approach assess resulting environmental implications. Accordingly, coupled groundwater flow transport model was invoked. The generated successfully calibrated for observed water levels salinity. proposed exploitation regime 102 wells each pumping 1000 m3/day simulated 100-year test period. maximum drawdown about 25 m, compatible with advocated restriction limit. Climate change (CC) impacts reducing lake’s storage increasing crops’ requirements were investigated. level fluctuations key factor in aquifer hydraulics direction. breakthrough considering CC catastrophic scenario (RCP8.5) increased by 20%. developed solute utilized simulate salinity spatial distribution lateral movement leaking pollutants from underway activities. Cultivation found feasible up 80 km away lake border does not exceed 2000 ppm. Yet, protection strip less than 4.8, 6.0, 7.2 according operating condition inevitable ensure that do intrude into lake. These findings will assist decision-makers scheming impact assessment criteria development.

Role of Smart Agriculture Techniques in Food Security: A Systematic Review

Journal of Agronomy and Crop Science, Год журнала: 2024, Номер 210(5)

Опубликована: Сен. 16, 2024

ABSTRACT Agriculture plays an important part in the overall growth and development of a nation. Concerns about agriculture continue to be recalcitrant obstacle path upward movement. Although agricultural yields are increased, however, low‐ middle‐income countries still have difficulty producing all required foods with current state technology. Smart is becoming increasingly farmers as means ensuring optimal field higher crop yield. This systematic study analysed briefly explained effects using smart techniques (SATs) from variety countries, including China, United States America, Australia, India, Philippine Islands, South Africa, Pakistan Iran, among others. Increased climatic change resulting abiotic stress other harmful on plants resulted decreased productivity under traditional practices. Stats literature shown that launching SATs has significant increase cotton–wheat rice–wheat yields, resultantly increased incomes farmers. Application SATs, satellite remote sensing, drones, machine learning image processing, monitoring, wireless sensor networks, IoT–based robotics, precision agroforestry could extremely useful developing intelligent systems underdeveloped improved plant growth, high yield food security. These technologies help by storing additional water, spraying pesticides practicing employing sensors for assessing different environmental parameters. By making efficient use these technologies, able their crops, which, turn, will contribute reduction poverty elimination insecurity.
