The objective of the study was to predict the forces that react with the implement parts during ploughing in the three (3) sampled areas in Bongo District. Soil samples were taken at a 30 cm depth. Laboratory tests were performed on them on triaxial, grading and Atterberg limits. The results were used to describe the soil and for the force prediction. There were some field tests to determine tractive efforts, speed of travel and ploughing depth. The three (3) soil types considered were sandy loam, loamy sand and course loamy sand. Food and Agriculture Organization classified the three (3) soil types as Lixisols and the local soil series also put all the soil samples as Tranchera. At the time of ploughing, the densities were ranging from 1.28 to 1.44g/cm3 and moisture content of 9.43 to 22.96%. The rake angle measured on the animal plough was 190, and the soil metal frictional angles of the three soil type ranged from 32.355 to 37.1290 with soil cohesion of 0 kPa for course loamy sand, 2.664 kPa for loamy sand and 56.338 kPa for the sandy loam soil. The resultant (P) forces for the three soil samples; loamy sand, sandy loam and course loamy sand were 0.5551 kN, 0.1024 kN and 0.0106 kN respectively.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":" 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In India, the groundwater level is declining in some parts of the country due to over-exploitation, low or negligible recharge of aquifer systems, and unsustainable development of groundwater resources. The groundwater modeling is an important tool for studying the past and present groundwater behavior and in the development of future strategies for sustainable groundwater management plans. To study the Impact of groundwater recharge on the replenishment of underground reservoir, Ballia district of Uttar Pradesh has been selected which is one of the districts of the most populous state of India, Uttar Pradesh. An attempt has been made to develop a groundwater model using Modflow software to simulate the groundwater trends and predict future groundwater heads. The calibration and validation of the model were done for 5 years and 3 years respectively. The correlation coefficient for calibration and validation was found 0.85 and root mean square errors vary from 2.89 to 3.2m variation in future trends of groundwater heads. The results of the study show that the developed model can be effectively used to predict the future groundwater heads. The groundwater flow was observed from the northwest to southeast direction. It was predicted from the study that groundwater draft will increase by 10% with a decrease in groundwater level by approximately 0.24 m in the north-west direction by the year 2025. However, no impact was observed in the south side of the district and it was predicted that the groundwater level would remain the same in this zone during the next 3 years.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141830496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, researchers from all over the world are focusing on solutions to tackle carbon emissions, with hempcrete emerging as a less polluting construction material. Hempcrete is a bio-composite comprising a woody core of hemp stem and hydrated lime. The objective of the study is to find out the physical and mechanical properties of hemp-lime concrete.  \u0000Study Design: The present research paper is part of the ongoing study on hempcrete at G.B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand, India. The present study chose an experimental research design.  \u0000Methodology: The study presents its results in two parts: performance and sustainability. The first part investigates the performance of hempcrete in terms of its physical and mechanical characteristics. The researcher conducted numerous trials to fix mix designs, focusing on their workability. Cubes of size 10 cm were cast manually for five distinct mix designs. The second part of the paper examines the sustainability aspect of hemp-lime concrete via a relevant literature review. \u0000Results: During the specified time intervals of 28, 56, 84, and 112 days, the cubes exhibited a range in weight density from 506 to 674 kg/m3. In parallel, the compression test results demonstrated varying values, spanning from 0.510 Mpa to 0.810 Mpa across the same time points. Results show that there is a negative correlation between density and compressive strength and a positive correlation between density and water absorption rate. \u0000Conclusion: The results pertaining to weight density highlight the lightweight nature of hempcrete, to the extent that the cubes have the propensity to float in water. Due to its relatively low compressive strength values, hempcrete is deemed suitable for non-load-bearing applications within building construction.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"39 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141643846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several components of these climate changes occurring globally that includes uneven rainfall, droughts, floods, warming of atmosphere etc. These are the most important challenges influencing natural ecosystems, agricultural productivity and food security. Climate change is not only influencing crop plants and forests directly but can also impact the pests of these crops. Weeds respond to climate change by changing the duration of their life cycles, population dynamics and shift to new habitats and become a potential competitor to crop plants thereby reducing the production and productivity of crops. Elevated temperature and elevated CO2 level in the environment interfere with herbicide activity, which affects the herbicide absorption, translocation and thereby reduces the efficacy of the applied herbicide. Weeds’ resistance to herbicides may probably increase due to further aggressive growth of weeds in future climate conditions, which can cause a decline in the efficacy of routinely used herbicides.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141640210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vahl, commonly referred to as globe fringerush, member of the Cyperaceae family, is a significant and widespread sedge weed in rice cultivation. This C4 plant is characterized by its tall, annual or perennial growth, featuring a fibrous root system and smooth stems, often producing vigorous tillers reaching heights of 80-90 cm. Seedlings of F. miliacea typically emerge shortly after rice is planted, with flowering occurring within about a month, capable of producing a second generation within the same growing season. Found extensively throughout tropical regions, especially in lowlands, F. miliacea thrives in environments such as rice fields, shallow water along ditches, and streams, notably prevalent across South and Southeast Asia, as well as Australia. This weed presents enduring challenges across diverse agro-ecosystems due to its various ecotypes, prolific seed production, rapid germination, vigorous growth, strong competitive abilities and allelopathic interactions. Temperature is a critical factor significantly influencing seed germination of F. miliacea which exhibits non-deep physiological dormancy. Light is essential for the germination of this weed showing positive photoblastic behaviour. F. miliacea thrives in saturated soils but fails to emerge from depths greater than one cm, emphasizing the importance of shallow tillage to manage weed emergence effectively. Effective weed management hinges on a deep understanding of the factors that favour its emergence and establishment. Adopting the germination ecology-based practices such as tillage, stale seed bed preparation, optimal planting density, water management and nutrient management can significantly improve the management of F. miliacea.","PeriodicalId":506431,"journal":{"name":"International Journal of Environment and Climate Change","volume":"38 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141649041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deficiencies in potassium, magnesium and sulphur are critical for enhancing both crop yield and quality. Additionally, agrochemical residues in soil, water and farm products pose significant challenges. Mahalaabh (K2SO4·MgSO4·6H2O), a combination of potassium, sulphur and magnesium, offers a balanced solution to address these issues. Field experiments were conducted during the Kharif season of 2023-24 at Agrocel Industries Pvt. Ltd., Kachchh, to evaluate the impact of Mahalaabh on castor, cotton and groundnut crops. The trials were executed in a Randomized Block Design, testing different doses of Mahalaabh powder through foliar spray, fertigation and granular soil application. The results demonstrated that Mahalaabh powder is effective in enhancing productivity across the tested crops. In castor, higher doses of 10 kg/acre through drip irrigation and 20g/L foliar application increased productivity by 22.3% and 14.3% over the recommended fertilizer dose (RFD), respectively. However, in cotton, lower doses of 6kg/acre through drip irrigation and 10g/L through foliar application were more effective, resulting in 3.8% and 5.3% yield enhancements compared to RFD. In groundnut, foliar spray at 15 g/L applied thrice at 30-35, 50-55, and 70-75 days after sowing (DAS) was effective, resulting in a 22.9% higher pod yield compared to RFD.

Moreover, notable effects were observed on the number of nodules, drier nodule weight, number of leaves and branches, pod load, pod and straw yields, and the weight of 100-pods. The highest carbon content (0.857; 0.861%), nitrogen content (0.081%; 0.087%), phosphorus content (7.488; 7.735 mg.kg-1), pH values (6.43; 6.54), and soil moisture content (24.80; 25.27%) were recorded in the homogeneous group of zaï and zaï associated to stone rows.

The paper will then focus on what response in national energy structures have been adopted by Central Asian countries to address global climate change commitments. The main focus of this paper is on how China’s renewable energy investment in Central Asia contributes to solving essential problems for sustainable energy transition, bridging technical gaps and financial barriers for the low-carbon sustainable energy transition and aligning with the Paris agreement to fulfill global climate commitments. The limited institutional capacity and market failure in renewable policy ecosystems in Central Asian countries jeopardizes domestic climate investment and China’s renewable investment potential, increasing national spending for sustainable development transition and triggering huge fiscal deficit and debt crises. This endogenous systemic risk deteriorates financial and technical barriers. This requires regional and multilateral renewables coordination and climate cooperation. China needs to set up a comprehensive green policy for the Central Asian countries to get full support from local and international society.
