Variation in soil organic carbon with structural composition of mangrove species in the Sundarbans

The world's biggest continual mangrove swampy land is the Sundarbans Mangrove Forest, which is crucial to both the terrestrial and marine carbon cycles. While numerous studies have focused on organic carbon variations within this ecosystem, few have explored the interaction between carbon stocks and the structural composition of mangrove species. This study sought to investigate the connection between soil organic carbon accumulation and functional attributes of vegetation (DBH, basal area). This study was carried out on four vegetative and two non-vegetative plots in three different sites within the oligohaline zone. Based on species Iv, the Karamjol area was prevalent by Heritiera fomes (Iv =139.3). In contrast, the Ghagramari area was predominated by Avicennia officinalis (IV =105.1). Accumulation of TBC, Avicennia officinalis presented the highest, despite having a smaller number of individuals within the study area. 1 m soil core was pulled out from each subplot of each main plot by using a one-meter-long open face peat auger. The forest areas exhibited maximum soil organic carbon accumulation, which was significantly (p < 0.01) higher than non-vegetative areas. Moreover, the mean soil C/N ratios in the Karamjol area (13.4±0.2) and Ghagramari area (13.2± 0.2) were significantly (p < 0.01) greater than those in the non-vegetative area (12.3±0.1). These findings suggest that regardless of the dominant species, species richness, or size (tall or dwarf) of the mangroves, a particular quantity of organic carbon is captured within the mangrove soil. Thus, when making future decisions, it is crucial to repute the role of the Sundarbans mangrove in the accumulation of organic and biomass carbon, which can directly affect mitigating global warming.

Growth Evaluation of Backcross Progenies BC2F1 Experiencing Submerg-ence and Non-submergence at BC1F1 and its Parents

The utilization of dual-resistant varieties that are resistant to soaking and drought in certain periods is an alternative to rice cultivation in swampy land. Inpara 8 is a variety that is confirmed to have SUB 1 gene, resistant to submerged stress and Inpago 5 is identified to be resistant to drought stress. Crosses were made between Inpara 8 (donor parent) with Inpago 5 (recipient parent), resulting in F1, then F1 was crossed back with Inpago 5 and produced BC1F1, then crossed back with Inpago 5 to become BC2F1. This paper contains an evaluation of the growth of BC2F1, which in the BC1F1 stage experienced submerged stress in the vegetative phase and which did not experience submerged stress. The research was carried out in August 2021 - January 2022 at the Greenhouse of the Department of Agricultural Cultivation, Faculty of Agriculture, Sriwijaya University. The results showed that in the vegetative phase, progeny BC2F1 TR has an average value of the highest per plant (113.64 cm) and the average per plant height Inpara 8 (3.93). In the generative phase, the fastest flowering time on the accession of BC2F1 TR (68 days), the fastest harvest time on Inpara 8 (122.93 days), while for the amount of grain per panicle, the amount of grain per clump, and dry weight on Inpago 5 (529.60 g, 2648 g, and 11.62 g). The average yield of BC2F1 progeny is more similar to Inpago 5 as the recipient parent. Both progeny have the same Sub 1 gene in them and can survive to produce, but Accessions that have experienced previous submerged stress are more vulnerable to growth so they have an impact on the resulting production.

WBGT ANALYSIS OF THERMAL COMFORT OF THE AREA OF SEMBERIJA

&amp;lt;p&amp;gt;Thermal comfort of urban areas is a highly researched field of science, which is gaining more and more importance in the field of ecology. The research of the area from the aspect of the convenience of physical activities and outdoor life provides data that is also useful in the health sector. This research included the area of Semberija in Bosnia and Herzegovina, which is characterized by unfavorable conditions during summer, due to high temperatures, swampy land and increased artificial presence of construction and industries.&amp;lt;/p&amp;gt; &amp;lt;p&amp;gt;Not all areas have the same weather conditions, therefore other factors such as relief and presence of forests are important in the overall state of the area. Therefore, data from two meteorological stations, at a short distance from each other, but in a different natural and artificial environment, were analyzed. These are the station in the town of Bijeljina and the station within the Mine and Thermal Power Plant in Ugljevik.&amp;lt;/p&amp;gt; &amp;lt;p&amp;gt;Within this research, the WBGT bioclimatic model was used, which is widely used in the world for the purposes of calculating the time that the human body can spend in direct sunlight during work or exercise, without rest. Given that the same time period is not covered, an average of 14 years (period 2005 &amp;amp;ndash; 2018) was analyzed for the area of Bijeljina, and an average of 8 years (period 2015 &amp;amp;ndash; 2022) for Ugljevik. The period from 2015 to 2018, which covers both locations, was also analyzed in order to make a comparison and notice the differences and determine the factors that affect the thermal comfort of the space.&amp;lt;/p&amp;gt;

Correlation Study of the Cone Penetration Test in the Field with a Laboratory Test on Soft Soil in Banjarmasin

The very soft soil commonly found in South Kalimantan, especially in Banjarmasin, with conditions of tidal swampy land, poses a challenge when it comes to the development of areas intended for medium-scale building construction. The demands of the population and the increasing need for housing necessitate the addition of residential levels, both by the government and private entities. This will undoubtedly open up new areas, and housing development will become a top priority in order to realize this. This research process is conducted in the field and in the laboratory, using soil material tested with the cone penetration test (CPT) method and data processing to identify the type and characteristics of the soil, ensuring they remain unchanged during the analysis of field data. Original samples are also taken for the purpose of analyzing the selection of foundation reinforcement types. Very soft clay soil is identified from the location of Gunung Meranti in Banjarmasin. This data is used for the analysis of bearing capacity, settlement analysis, characteristics, and identification, which will be correlated with the results of previous testing conducted in the laboratory using the Unconfined Compression Test (UDS) method in nearby locations. The results of field investigation data in the form of manometer readings are expected to assist the author as indicators in measuring and analyzing the type and characteristics of the soil, as well as the bearing capacity of the subgrade soil in the laboratory, based on the results of the CPT

This study aims to assess the suitability of land for corn and soybean plants. The research has been carried out in January to March 2020 in the swampy land of Tanjung Sejaro Village, Indralaya District, Ogan Ilir Regency. This research uses an intensive level survey method with an area of 5 ha. Observation and measurement were made directly to the field using a 1: 5000 scale map. The sample points consist of 10 points taken by the grid method, at each point representing 0.5 ha. Soil samples taken at a depth of 0-20 cm from the ground surface. The variables observed in the field were that the drainage class was rather poor, the effective depth was generally &gt;90 cm, the topography was flat (&lt;3%). The parameters observed in the laboratory were chemical properties in the form of very acidic soil pH in the range of 3.97-4.37, CEC classified as low with a range of 7.50-15.00 cmol/kg, Total nitrogen was very low with a range of 0.01-0.08 %, Phosphorus available was classified as very low with a range of 0.25-4.60 ppm, Potassium available was classified as very low with a range of 0.19-0.38 cmol/kg. The results showed the actual suitability for corn and soybean plants was N (not suitable) with several factors limiting nutrient retention and available nutrients. If liming and fertilizing inputs are given, the potential suitability for corn and soybean plants is S2.

CRITICAL RISK ANALYSIS OF TOLL ROAD PUBLIC-PRIVATE PARTNERSHIP (PPP) PROJECT CONSTRUCTION PHASE

Limited funding in meeting the financing needs for the provision of toll road infrastructure makes the government need to look for alternative financing so that the project can still be carried out. Public Private Partnership (PPP) is an alternative option to overcome this problem. However, infrastructure projects with PPP schemes require large investments and a relatively long concession period, thus allowing risk uncertainty to arise as a result of decisions made during the project. Risk identification in a construction project is important at the beginning of the project. This study was aimed at identifying critical risks, determining risk allocation and risk mitigation strategies, and analyzing the interrelationship between critical risks. The case study was conducted on the Trans Sumatra toll road project in South Sumatra. Quantitative data (questionnaire survey) and qualitative data (interview) were collected from the toll-road private sector. The results of the study identified five critical risks in the construction phase (CP) of the toll road project along with the allocation of risks, namely the risks of geographical conditions (shared), delays in work progress (private sector), design errors (private sector), force majeure (shared) and weather conditions (shared). The mitigation strategy for the risks of geographical conditions and design errors was to redesign the construction structure by adjusting with the land conditions of the toll road. Force majeure (Covid-19) causing delays in work progress required rescheduling and recalculation of construction costs. Weather conditions (heavy rain) occurring on swampy land caused puddles/floods; this condition caused delays in construction work. The mitigation strategy that could be carried out was by coordinating with the Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG) in the region and preparing disaster management Standard Operating Procedures (SOPs). The cause and effect of each risk showed that the critical risks in the construction phase of the toll road project were interrelated to each other which the risks would finally contribute to the increase in the construction costs of the toll road project.

Large-scale stresses, decay of River Jamuna and resilience strategies in the Anthropocene

In the recent decades, many worlds' large rivers have been exceptionally modified by human interference. The principal objective of this study is to investigate the causes and consequences of decay of river Jamuna (distributary of river Bhagirathi-Hooghly). The entire investigation was conducted by the data of historical maps like Rennel's map of Bengal, Hunter's map, digital version of US army map, landsat satellite imageries (1980-MSS, 1990-TM, 2000-TM, 2010-ETM+ and 2020-OLI) and fluvio-hydrological study. Maximum likelihood classification algorithm was used to delineate the land use and land cover classes and Kappa based accuracy assessment indices were also used for the validation. There is no scientific work on this historically important river and afterward, millions of people are also underprivileged from this river ecosystem services due to severe degeneration. In this milieu, it is a genuine research gap. Novelty of the work is exposed the authentic causes of river decay and anthropogenic stressors. Result showed that the average width of river Jamuna has been significantly decreased whereas maximum average width of the channel was recorded in the year 1956 (319.81 m) and the present channel is flowing comparatively within narrow path (69.27 m). Rate of siltation (average rate of siltation 0.23 m/year) on channel bed has been increased due to impacts of channelization. Channel bed, natural levee and proximity floodplain have been encroached by large scale human intervention. LULC patterns showed that the urban built-up area is rapidly amplified from 2000 (22.26%) to 2020 (31.50%) whereas, agricultural and swampy land turned into built up area. Off-take of Jamuna is completely detached from the parent river Bhagirathi-Hooghly in the early 1956 and gradual anthropogenic interferences within river corridor accelerate river decaying processes. River restoration is highly required for sustainable river ecosystem health management and environmental development. Some management strategies have been recommended such as reconnecting of river Jamuna with Bhagirathi-Hooghly, dredging, decommissioning of culvert and sluice gate, cleaning of fishing pool and water hyacinth and sustainable land-use planning.

Using Ethanol Degradation as Accelerated Chemical Seed Ageing Indicator For Different cultivars of Soybean

Indonesia has a wide range of swampy lands that need to be recovered for safe agriculture. The swampy lands and vegetation are a source of soil contamination through root exudates that need serious improvement. The plant exudates in soil could disturb seed germination. This study aimed to determine the effect of ethanol vapor treatment on the decrease in the vigor of four soybean seed cultivars. This study used a randomized block design with two treatment factors, namely ethanol-based ageing treatments as the main factor and cultivars as subfactor. The observation variables consisted of the percentage of germination, growth rate, vigor index, sprout length and sprout dry weight. The results showed that there was an interaction effect between fast ageing time and ethanol treatments and soybean cultivars which caused a decrease in the seed vigor. The soybean seeds of the cv. Gema was able to maintain more vigor compared to the cv. Grobogan which experienced more decline in germination. The 5 minutes of ageing time induced fewer damages with the highest vigor while 20 minutes of ageing the seeds induced maximum damage with the lowest seed vigor.

&#x0D; This study aims to analyze the need for agricultural machinery to support a cropping index of 200 in swampy land. This research was conducted in August 2021 in Muara Abab Village, Rantau Bayur District, Banyuasin Regency, South Sumatra Province. This study used a descriptive-tabular method, while collecting primary data using survey techniques and semi-structured interviews. Secondary data collection was obtained through a literature study conducted to collect data on institutions and policies supporting the development of agricultural tools and machinery. The data obtained was processed descriptively and analyzed to see farmers income and the data is presented in the form of tabulations. The results showed that the total income of lebak swamp farmers was IDR 8,963,625.00/ha/year. To support the activities of the index cropping 200, it is necessary to add additional agricultural equipment such as 5 units of 2-wheeled tractors, 1 unit of 4-wheeled tractors, 9 units of water pumps, 5 units of combine harvesters, 14 units of threshers and dryer as much as 2 units.&#x0D; &#x0D; Keywords: agricultural machinery, swampy land, cropping index 200, productivity

Landscape ecological risk assessment and transformation processes in the Guinean-Congolese climate zone in Benin Republic

The landscape of Ramsar site 1018 in Benin Republic is increasingly modified by different types of land use. Understanding these changes dynamics is essential for efficient resource management. The aim of the research is to identify the spatial configuration of landscapes using landscape indices, which are the indicators and guide for agricultural policy. Fragstats 4 software helped for computing landscape metrics. Landsat imagery were analysed using Arcmap 10.7.1 and ENVI 5.3 software. The landscape of the Ramsar site is composed by the natural land (forests, savannahs, swamp formations), semi-natural land (plantations), anthropized land (agriculture lands, built-up area), and water land. These ecosystems have changed according to different trends 1990–2000, 2000–2020 and 1990–2020. The agricultural land showed an increasing trend of 143%, following by the built-up area (37%). From 1990 to 2020, a decreasing of 45% has been observed in the savannah land, plantation land (41%), forest land (30%) and swampy land (17%). Also, the Ramsar site ecological context is at medium level despite the increasing of the landscape Ecological Risk Index: 0.1899, 0.2128, and 0.2165 in 1990, 2000, and 2020, respectively. Between 1990 and 2000, the creation process occurred in the built-up area and agriculture land, attrition within forest and plantation classes, dissection in swampy land, aggregation for savannah and shrinkage in water area. From 2000 to 2020, the agriculture land and swampy land continued to experience the same spatial transformation processes respectively. Dissection has observed within the forest land, attrition in water area, and aggregation for built-up area. The perforation process has observed within plantation, and fragmentation in Savannah. Finally, the development of agricultural activities and built-up areas are leading to change in the spatial structure of the Ramsar site landscape. To better conserve the biodiversity of these area, it will be necessary to characterize the still natural ecosystems. This will make it possible to propose a comprehensive management plan that integrates the agricultural and urbanization policy of the government, and the sustainable development goals.

GIS AND REMOTE SENSINGBASED RECONNAISSANCE OF VEGETATION ANDAGROFORESTRY AREAS IN SOUTH 24 PARGANAS, WEST BENGAL, INDIA

Accessing the advantages of combining GIS with remote sensing could be better utilised for specifying vegetation cover including agroforestry systems in South 24 Parganas district with farm lands and ponds historically shaped out of mostly swampy lands covered with jungles and the Sundarbans crisscrossed with creeks and rivers in the south-easternmost part of West Bengal state in India by image processing based on updating of data or information in the form of maps or attributes. Such analysis for this district was performed mostly at the intervals of five years from 2005 to 2019.Changes in expanse of vegetation areas were classified in land coverage under deforestation and revegetation. Such changes are distinguishable through NDVI image values in the form of maps of the district and subdivisions, created on the Arc GIS 10.8 and ERDAS Imagine 2015 platforms by retrieving data of Landsat 4 - 5 TM Level 1 and Landsat 8 OLI/ TIRS Level 1 imageries as retrieved from USGS website. Healthy vegetation including agroforestry were sorted out through demarcation of highest indices of NDVI data. Areal extents of less than 10 ha of healthy vegetation were sorted out as areas either under new plantation or horti-agri or agroforestry. Individual agroforestry systems were found out with the help of Google Earth Pro. Monitoring of vegetation cover as well as agroforestry will be helpful to achieve SDG 15 and, thereby SDG 2 and 8 as defined by the UN for conservation of life on land as well as zero hunger including decent work and economic growth.

Yield Gap in Cayenne Pepper Production in South Kalimantan

Swampy land is potential land for the development of cayenne pepper. However, there is a yield gap between swamp and dry land plants. The gap in the yield of cayenne pepper plants between dry and dry land is caused by the acidity of the soil in the swamp land which results in low cayenne pepper production

Localization of production-destruction processes by distribution of phosphate in the estuaries of Uda and Usalgin Rivers (Okhotsk Sea)

The areas with prevalence of either production or decomposition of organic matter are localized in the estuaries of Uda and Usalgin Rivers (western coast of the Okhotsk Sea) on the data of chemical survey conducted in conditions of summer flood in July, 2016, interpreting patterns of non-conservative variations of inorganic phosphorus concentration (deflections of observed values from potential values determined by the river water mixing with the seawater). Sign of production-destruction balance changed along both surveyed estuaries: the organic matter decomposition prevailed in the internal estuaries but its production prevailed in the upper part of the external estuaries. Another common feature of both estuaries was active recycling: the larger portion of organics was produced with utilizing the phosphorus mineralized within the estuaries, but not the terrestrial phosphorus provided by the rivers ionic discharge. Extremely intensive recycling was observed in the Usalgin estuary that drained swampy lands.

Hydrology of the palmar state reserve, yucatán, México: hydrological budget of petenes

Throughout the coastal zone of Yucatan state (Mexico), between the coastal sandbar, and the land with low dry forest, are the flooded low forest, mangroves, and swamps. It is within these swampy lands, where are found numerous arboreal islands or petenes (local name). It has been outlined that its importance is because the water contribution from springs to the basin. As a contribution to the knowledge of the petenes, it was developed a hydrological monitoring system to estimate the hydrological budget of a petén located 3 km southwest of the population of Sisal in the restoration zone of the Palmar Reserve, Yucatan. The analysis showed that the groundwater inflow represented 92 % of the total of inflow to the system, with the net precipitation representing only 6 % and the surface inflow 2 %. By the other side, the surface outflow represented 40 % of the total of the outflow of the system, the groundwater outflow 20 % and the evapotranspiration 40 %. The annual total balance resulted negative (it means fluxes out of the petenes) with a volume from storage of about – 129,288.28 m3. The springs in the interior of the petenes can become more determinant in the hydrologic balance of the community than the contribution of the pluvial precipitation, the hydrodynamics of swamps, or the influence of the waters of the sea.

Marginal Substitution and Allocative Efficiency Evaluation of Rice Farming Applying Organic Fertilizer In Swampy Land Banyuasin Regency, South Sumatera Province, Indonesia

The growing awareness of the negative impact of using inorganic fertilizers on the environment in a small number of rice farmers has made them switch from conventional to organic farming. So far, economic research on the application of organic fertilizers has been widely carried out in irrigated rice fields. Economic research on the application of organic fertilizer use in tidal and lebak land areas has not been widely carried out. Differences in land types are expected to affect the amount of use of organic fertilizers and are also thought to affect production yields and income levels. The purpose of this study was to analyze the reduction in the use of inorganic fertilizers for rice farmers using organic fertilizers and their marginal substitution, as well as the impact of using organic fertilizers on the costs and income of rice farmers using organic fertilizers in tidal and lebak land. This research was conducted in Telang Sari Village, Tanjung Lago District and Sako Village, Rambutan District, Banyuasin Regency, South Sumatra Province, Indonesia. Data was collected in April 2021. The research method was a survey with proportional stratified random sampling. The results showed that (1) the highest reduction of inorganic fertilizer in tidal land was 65.4 percent, while in lebak land it was 57.6 percent; the cost of production factors in tidal and lebak and areas increased by 4.94% and 18.56%; The income of rice farmers in lebak land increased by 60.58%, while on tidal land it was only 32.94%, (2) The marginal substitution of organic fertilizers to inorganic fertilizers was -2.61 and -5.68, (3) The use of these factors production for farmers who use organic fertilizers in both tidal and lebak land have not been efficien yett. The use of factors of production must be increased to obtain optimal profits.

Local Communities and Separate Space: The Zionist Stance on Jewish Settlement in Arab Cities—The Case of Acre

This article looks at the impact of harsh environmental conditions on the development of the Zionist narrative and the pursuit of Jewish urban settlement in Arab cities, specifically Acre. While overcoming adversity was part of the Zionist farming ethos, settling in areas that were environmentally challenging was one of the factors that kept the Zionist establishment from acknowledging or supporting urban Jewish settlement in Arab towns. In fact, the openly professed ideology of settling in such locations and creating mixed cities was implemented only in the few cases where an economic or political incentive existed. These incentives aside, environmental issues like swampy land and seasonal flooding were major inhibiting factors, not only affecting the scope of Jewish settlement but also the way they were addressed in the Zionist narrative.

Impact of calcification on potato yield

By seed surfaces according to the information the Federal Bureau of Statistics and the Institute of Statistics Republic of Srpska of the total area under vegetables potatoes occupies 57% sowing area, so that after the corn and wheat, potatoes the most important agricultural plant in Bosnia and Herzegovina. Most are lighter types of land - permeable, loose, sandy-humus and sandy-clay ground with crumb structure, rich in mineral and organic matter, with favorable water – air characteristics. Does not match his tough swampy lands with a high level of underground water. Tolerate acid soil reaction, and the optimum pH is 5,4-6,5. Given that the area of Tuzla canton mainly acid soil with pH values from 4.5 to 5.5 made the production of a sample on the plot that had a pH value of 4.6 as a material for the reparation of land or quality of calcification was Fertdolomit in order to increase in pH, after you apply Fertdolomit analysis has found that the increased pH value to 5.8. Calcification is a measure of repair of chemical properties of soil, primarily reducing its acidity, ie. bringing the pH value to the optimum level for the cultivation of certain plant species calcium use of fertilizers. At the same time, this measure of the repair water-air, mechanical, physical and biological properties of soil. Reflected in the potatoes plant in four different variants: the control, with the use of 40 t / ha of manure, the use of 40 t / ha manure and NPK 7:20:30 400 kg / ha and the use of manure 40 t / ha, NPK 7:20: 30 in the amount of 400 kg / ha with supplements Fertdolomit in the amount of 3 t / ha. The results reflected a big point to the importance of calcification in the production of potatoes.
