Revolutionizing Forestry: Remote Sensing and GIS for Sustainable Forest Management: a Review
Remote sensing (RS) and GIS are vital tools for forest management, aiding in policy formulation, planning, and decision-making. They provide crucial information on forest resources, making management tasks like recording, updating, and monitoring more efficient. RS and GIS enable forest cover mapping, change detection, land use/cover change analysis, and forest type mapping across different spatial scales. They support forest protection efforts through forest fire detection, burnt area mapping, and forest health assessments. These technologies are also essential for biodiversity mapping, afforestation planning, wildlife habitat conservation, working plan preparation, boundary demarcation, encroachment mapping, harvest scheduling, and climate change studies. With advancements in technology, RS and GIS have become increasingly popular for managing forest resources. As foresters handle diverse objectives—such as determining allowable cuts, maintaining biodiversity, and conserving soil and water—reliable spatial data are essential for developing effective GIS-based forest management plans.
Ureapolyacrylamide modulates the composition of functional microbes and biochemical properties in maize and rice rhizosphere from Indo-Gangetic plains, UP, India
The versatility use of polyacrylamide has gained momentum in the recent past with its targeted use as a fertilizer when combined with urea through polymerization under specific conditions to develop ureapolyacrylamide (UPAM). After polymerization, ureapolyacrylamide of can be developed into four various grades with respective nitrogen (N) and carbon (C) concentrations (UPAM-1: C-35.35%&N-32.35%; UPAM-2: 27.67&39.40%; UPAM-3: 25.11&41.61; UPAM-4: 23.83&42.71). The experiment laid out in a randomized block design with three replication and ten treatments consisting of the following T1-absolute control, T2-UPAM-1, T3-UPAM-2, T4-UPAM-3, T5-UPAM-4, T6-UPAM-1, T7-UPAM-2, T8-UPAM-3, T9-UPAM-4 and T10-neem coated urea (NCU), here T2 to T5 treatments are two split applications and T6 to T10 treatments are three split applications. The objective of this study was to assess the effect of various grades of UPAM application on soil microbial enumeration, soil microbial biomass, and enzymatic activity in rice and maize rhizosphere. The study showed dominant soil microbial enumeration, enzymatic activity, and microbial biomass under two (T3) and three (T7) split applications of UPAM-2 grade polymeric N treated plots in maize and rice crops. There is a significant impact on dehydrogenase and urease enzyme activity and a non-significant impact on microbial biomass carbon, soil alkaline phosphatase activity, and soil microbial enumeration in both crops. The results also showed that the application of various grades UPAM along with SSP and MOP indicated a positive impact on soil biology, and no negative impact was recorded in both crops under two consecutive crops.
Screening of Promising Rapeseed-Mustard Genotypes/cultivars against Alternaria blight under naturally epiphytotic conditions
Alternaria blight is one of the major biotic stresses causing heavy yield losses to the mustard crop, globally. An experiment was conducted to evaluate some rapeseed-mustard genotypes for Alternaria blight under field conditions during Rabi 2022-23 and 2023-24. The observation on disease severity, infection rate and area under disease progress curve (AUDPC) were recorded periodically and calculated as per standard procedure. Detailed analysis of data on all aspects like- PDI (%), infection rate (r) and AUDPC of each genotype/cultivar exhibited out of 262 genotypes/cultivars genotype/cultivar was found highly resistant, only 07 genotypes/cultivars found resistant, 90 genotypes/cultivars moderately resistant, 94 genotypes moderately susceptible, 63 susceptible and 8 genotypes highly susceptible indicating that substantial variation with genotypes towards disease reaction exists against the Alternaria brassicae New Delhi isolate. A total 97 genotypes were found resistance and moderately resistant with minimum PDI, apparent rate of infection and AUDPC. Among all the resistance genotype NB-115 was found best with PDI (3.42), apparent infection rate (0.061924) and AUDPC (68.3625). These resistance sources can be used in breeding programme to develop resistance cultivar for management of Alternaria blight.
TECHNO-ECONOMIC ASSESSMENT OF MINI TRACTOR GRABBER (MTG) FOR THE OIL PALM FFB EVACUATION
Efficient fresh fruit bunch (FFB) evacuation is a crucial process in the supply chain for oil production. Sustainable methods for the process are increasingly important. Mini tractor grabber (MTG) is a technology used for FFB evacuation that combines a small-size tractor, a one-tonne trailer, and hydraulic arms. Its operational benefits and potential for sustainable practices make it a promising prospect. The most significant impact of MTG is the reduced need for manual labour, allowing businesses to save costs and conserve resources. This paper evaluates MTG technology's technical and economic benefits for the oil palm FFB evacuation. A five-year study in a Malaysian Palm Oil Board (MPOB) model plantation site was carried out extensively to evaluate the performance of MTG, which had never been conducted before. Results indicated that the cost of operation is RM 7.80 per tonne of FFB, with factors such as repair and maintenance being found to be more than 35% of the total cost. The breakdown analysis indicated that repairs and maintenance were significant for the mechanised operation and would require attention from management if the oil palm mechanised system was introduced. Besides that, MTG operation provides numerous benefits to the industry and the nation, especially in increasing the efficiency of the FFB evacuation process.
The vegetation of the Wadi El Faregh Ain Oulmene-Setif (North Est of Algeria)
One of the most significant streams in the area is Wadi El Faregh, located south of the Setif Wilaya in eastern Algeria. It is 20 km wide and ranges in elevation from 915 to 1322 meters. The Wadi flows into the Soubella Dam after originating from Cherne. The climate around Wadi El Faregh is semi-arid, characterized by relatively low rainfall and dry weather, with cold winters. The soil composition is primarily limestone. In the study, 23 plots were used as a sampling method to evaluate vegetation and examine the distribution of perennial plant species in the region. A total of 102 species from 37 distinct families were identified. Among these families, Asteraceae was the most represented, accounting for 16 species. In terms of biological forms, therophytes made up 39% of all known species, making them the most prevalent category. Therophytes are plants with a short life cycle that complete their life cycle within a single growing season. The overall Shannon-Wiener diversity index was 2.39, and the Simpson index was 0.94, indicating that the diversity in the Wadi is relatively high.
