From the Introduction:

"Thank you, Professor Suzanne Keller. Introducing such a distinguished and world renowned figure as Professor Maki makes my task very easy and allows me to be short as he does not need much introduction. Naturally, if I only had to hint at some aspects of his life experiences, performance and achievements, the time needed would be much longer. But I am happy not to have to go into this and just welcome Professor Maki as my teacher, as an architect/urban designer who first introduced Doxiadis to Japan in the early 1960s by giving a lecture in Tokyo regarding Doxiadis Associates..."

A diagnostic study of interannual variability of Indian summer monsoon using outgoing longwave radiation (OLR) data
Authors: PAI D.S.
Published: December 2021

ABSTRACT. Using the monthly outgoing longwave radiation (OLR) data obtained from NOAA polar orbiting satellites, during the period 1979-92, composite OLR anomalies in respect of good monsoon years (1983 and 1988), bad monsoon years (1982 and 1987 for the case associated with ENSO and 1979 and 1986 separately for the case without ENSO) and normal monsoon years (1980, 1981, 1984, 1985, 1989, 1990, 1991 & 1992) were examined. The computation has been performed over the global tropics (30°N-30°S) bounded between the longitudes 50°E and 130°W (through date line) on 5° longitude × 5° latitude grid.

There are significant differences in the spatial distributions of composite OLR anomalies between these four cases from the month of April to September indicating spatial and temporal changes in the organized convective pattern. For the good monsoon years persistent negative anomalies indicating enhanced convective activity were observed over the Indonesian regions, whereas large positive anomalies indicating depressed convective activity were observed over equatorial Pacific just west of date line. During the bad monsoon years above normal convection was observed over Pacific region (ENSO case) and over equatorial Indian Ocean (Non ENSO case). During normal monsoon years the spatial patterns of OLR anomalies were similar to that of good monsoon years, but with weaker anomalies. These observations can be explained through the relative interaction between tropical convergence zone (TCZ) over the Indian sub-continent and that over the north Indian Ocean and Pacific. The eastward shift of the convective activity during El-Nino years can be attributed to shift/reversal of Walker circulation. There are strong signals of OLR anomalies during pre-monsoon months which may be useful in inferring the nature of the subsequent monsoon activity.
Sub-seasonal variations of the tropical storm track in the western north Pacific
Authors: WANG BIN , WU LIGUANG
Published: December 2021

With 20-year (1975-94) climatological data, we demonstrate that the tropical storm track over the western North Pacific (0° - 40°N, 100 - 180°E) exhibits prominent sub-seasonal variations on a time scale of about 40 days from May to November. The storm track variability is regulated by the conspicuous Climatological Intra Seasonal Oscillation (CISO) in the strength of the western North Pacific summer monsoon and the associated position of the western Pacific Sub-tropical High. The CISO cycle regulates the number of tropical storm formation during the Pre-Onset and Withdraw Cycles but not during the Onset and Peak Monsoon Cycles (from mid-June to mid-September).

Published: December 2021

The tropical cyclone is one of the most destructive natural disasters which is capable of causing loss of life and damage to the property. Strong winds, heavy rains and storm surges associated with the cyclones, are the phenomena which are responsible for causing the damage. The issue of warnings about the impending cyclones in time help to reduce the loss of lives that the cyclone causes. To forecast its formation, structure and movement, the processes involved in its evolution and subsequent movement, are to be understood well. In this article an attempt has been made to review the literature about the cyclone characteristics and its structure. Synoptic methods of forecasting its formation and movement are also reviewed. Existing literature on their association with QBO and ENSO is also summarized. Some forecasting rules that may be of help to an operational forecaster are mentioned.

Published: December 2021

ABSTRACT. In this paper we have tried to set up a mathematical model that will show the contribution of wind-induced surface waves of the ocean, on surges in shallow basin of Bay of Bengal. For this, the energy balance equation, excluding non-linear forcing term, is considered and solved by Lax-Wendroff integration scheme. Wind is specified over all the grid points following Cardone' s formulation. The hydrodynamic equations in linearised form as used by Jelesnianski have been considered and using Shuman's algorithm, those equations have been solved. In the process of solving these equations, the output of the energy balance equation is included as wave set up term to incorporate energy contribution of wind waves to surges. The estimated surge height is compared with and without considering wave contribution.

Published: December 2021

O corpo é historicamente atravessado por processos de subjetivação que vigoram diferentemente a cada tempo. Atualmente, ele tem se desenvolvido segundo os imperativos da racionalidade neoliberal, que é uma configuração específica do capitalismo proveniente de flexibilidade, com alto desempenho e produtividade. Nesse cenário, o sujeito tende a compreender aos valores capitalistas como naturais e indispensáveis para vida. Exemplo disso é o profissional denominado freelancer que atua sem garantias dos vínculos empregatícios e recebe por dia ou hora trabalhados. Capturado pelos valores disseminados pela racionalidade neoliberal, esse profissional se torna a personificação do empresário de si mesmo, colocando-se como alguém flexível e que zela pelo aprimoramento constante do desempenho. O presente artigo teve como objetivo compreender como o corpo do trabalhador freelancer se conecta a essa racionalidade neoliberal, fortalecendo-a. Adotando uma metodologia qualitativa, descritiva e de campo, foram combinados roteiros semiestruturados com três trabalhadores freelancers. Os dados apresentam como exigências recaem sobre o corpo desse trabalho a fim de que o mesmo desenvolva novas características e utilidades compatíveis com tais valores. Valendo-se de tecnologias de comunicação, o trabalhador é convocado a colocar em cena suas relações sociais e afetivas com vistas a ampliar a produção. Ao final do estudo foi possível constatar que o freelancer se tornou uma espécie de modelo para o trabalho contemporâneo à medida que se conecta à racionalidade neoliberal, reproduzindo e reforçando seus pressupostos.

Published: December 2021

The COVID-19 pandemic is considered different from previous pandemics because of the extent and number of people infected. The impact of the COVID-19 pandemic has made almost all joints of the world economy sluggish, as a result it is estimated that the world economy will be in a recession. This also applies in Indonesia, where economic growth is not as expected. One of the sectors most impacted by this virus is the tourism industry and its derivatives, so it is very important to know and determine the right strategy in managing and seeing tourism opportunities in the midst of the pandemic and the aftermath as an effort to develop the world of sustainable tourism. The purpose of this study was to determine the impact of tourist satisfaction and perceived quality on the intention of halal tourism in the midst of a pandemic and in the future. Research on travel intentions in the midst of a pandemic, especially during the COVID-19 period, is still very limited, so that it will have an impact in the future, so further research needs to be carried out in a different context from the limitations of previous research. The research stages include; data observation, determining the main problem, the purpose of the activity, literature study, data collection, data processing, analysis of results, and evaluation of research results. This research is based on the theoretical framework of Destination Attributes and Perceived Quality. This study seeks to analyze the intentions of tourists traveling in the midst of the COVID-19 pandemic among the people of Aceh, Indonesia, and world tourists who travel to Banda Aceh City, Aceh Province. The data analysis method used a partial least squares (PLS) statistical approach with the structural equational model (SEM) method to see the direct and indirect effects (mediation). The findings of this study are expected to contribute to more effective planning for restoring the tourism business, specifically halal tourism and for the development of measures for destination attributes and visitor satisfaction and security in tourism services, now and in the future. The outputs in this study consist of research reports, articles in accredited national journals and produce HKI (copyright). The resulting TKT level of research is TKT 3.

Bibliometric analysis is the application of statistical methods to quantitatively analyze scientific publications. It makes it possible to evaluate the production of a laboratory, a journal or a field of research. The objective of this study is to carry out an analysis of the scientific literature published on succession in the field of family business over the last thirty years. Two different types of indicators were used. The first concerns the activity indicators, which provides information about the productivity of journals and authors. The second is about co-citation analysis which gives an idea of the links between researchers, and co-word analysis which identifies interactions and relationships between different research topics. The results obtained reveal that it is a relatively recent area of research with strong connections between authors. Gaps in the literature as well as future research directions are also presented.

Published: December 2021

Abstract: The Borobudur area has grown into a world-class tourist destination. With the existence of Borobudur, Mendut, and Pawon temples, the area was appointed as National Strategic Tourism Area (NSTA). The condition influences the villages surrounding it. Borobudur village, Wanurejo, and Candirejo have developed into alternative tourist villages. During their development, these villages have undergone several transformation stages, which are interesting for further observation. In this background, the study aims to identify the transformation stages of the tourist villages in the Borobudur area, from the beginning as a people settlement to become tourist villages, and what causes the development of these stages. This study used a multiple-case study method with diachronic time series analysis, with three village units of analysis: Borobudur, Candirejo, and Wanurejo. Therefore, it will produce the stages of the village's transformation, especially, those related to tourism activities in the Borobudur area. It is expected that the results of this research will provide tourism development guidelines at each stage of the transformation of tourism villages so that they can be the basic for proper tourism planning for the government in rural tourism, especially in the development of tourism villages in NSTA. In addition, it can also be the basic of a scientific approach in researching the development of tourist areas, especially tourism village.
EXPERIMENTAL INVESTIGATION INTO FACTORS AFFECTING THE TRANSIENT FLOW OF FLUID THROUGH AN ORIFICE IN REALISTIC CONDITIONS
Authors: Wood C D , Hudson D A , Tan M , Sobey A J , Wang Y
Published: December 2021

During operations, damage can occur with a resulting ingress or egress of fluid. The incoming water affects the reserve buoyancy and it can also change stability and hull girder loading. During a flooding event it is vital that the flow through the damaged orifice and the movement of floodwater around the structure can be predicted quickly to avoid further damage and ensure environmental safety. The empirical measure coefficient of discharge is used as a simplified method to quantify the flooding rate. In many internal flow applications the coefficient of discharge is estimated to be 0.6 but recent research shows that it can vary considerably when applied to transient flooding flows. This paper uses an experimental setup to investigate how changes to the orifice edges and position within the structure affect the flow. It is then used to investigate the coefficient in a more realistic scenario, a static compartment in waves.

SHOCK RESILIENCE OF STRUCTURAL PILLARS IN NAVAL VESSELS
Authors: Rigby J C , Moss C , Thomas G
Published: December 2021

Although structural pillars are extensively used in commercial vessels, traditionally their use on board UK warships has been discouraged. This is due to the tendency of pillars to “punch through” the deck when subjected to the high impulse loading of shock from underwater explosions (UNDEX). There are however many spaces within naval ships that would significantly benefit from the wide-open spaces created from the use of pillars as opposed to full bulkheads, such as machinery rooms, mooring decks and accommodation flats. This paper re-addresses the question of a shock capable pillar, looking at how a pillar can be designed or mounted to increase its resilience to shock from underwater explosions. It is proposed that the advice against the use of pillars in warships could be unfounded; this is supported by the fact that not all navies reject their use. The results of this study imply that as long as the pillar is sited properly on primary structural members, then pillar buckling should occur long before “punch though”.
OPTIMAL NAVAL PATH PLANNING IN ICE-COVERED WATERS
Authors: Aksakalli V , Oz D , Alkaya A F , Aydogdu V
Published: December 2021

The Northern Sea Route (NSR) links the Atlantic and Pacific oceans through the Arctic and it is critical for global trade as it provides a route between Asia and Europe that is significantly shorter than the alternatives. NSR is soon expected to open for intercontinental shipping due to global warming and thus presents tremendous opportunities for reductions in shipping time, cost, and environmental impacts. On the other hand, facilitating this route requires innovative approaches due to the navigation risks associated with its ice-covered waters. This study presents a graph-theoretical approach for optimal naval navigation in ice-covered sea routes with flexible turn angles based on the idea of large-adjacency grid graphs. Our model allows for asymmetric left and right turn radii as well as turn speeds that vary as a function of the turn angle and it offers natural-looking navigation paths.
APPLICATION OF FUZZY FMEA TO PERFORM AN EXTENSIVE RISK ANALYSIS IN MARITIME TRANSPORTATION ENGINEERING
Authors: Akyuz E
Published: December 2021

The nature of maritime transportation involves numerous hazards, which can lead to serious consequences for human life, marine environment and ship. Therefore, achieving a high level of safety is recognised as paramount in maritime industry (Akyuz, 2016). In order to achieve this purpose, this paper prompts a fuzzy based Failure Mode and Effects analysis (FMEA) to perform an extensive risk analysis in the maritime transportation industry. The method has capable of identifying potential failures and calculating risk priority number (RPN) by capturing nonlinear casual relationships between the failures. The proposed method is applied to hatch cover failures in operational aspects in bulk carrier ships since potential failures of hydraulic hatch covers have serious concerns for ship owners. Besides its theoretical insight, the paper has practical benefits to ship owners, superintendents as well as safety professionals by identifying potential failure and offering early corrective actions.

Published: December 2021

A methodology for risk analysis applicable to shipping in arctic waters is introduced. This methodology uses the Bowtie relationship to represent an accident causes and consequences. It is further used to quantify the probability of a ship accident and also the related accident consequences during navigation in arctic waters. Detailed fault trees for three possible ship accident scenarios in arctic transits are developed and represented as bowties. Factors related to cold and harsh conditions and their effects on grounding, foundering, and collision are considered as part of this study. To illustrate the application of the methodology, it is applied to a case of an oil-tanker navigating on the Northern Sea Route (NSR). The methodology is implemented in a Markov Chain Monte Carlo framework to assess the uncertainties arisen from historical data and expert judgments involved in the risk analysis.
PREDICTION OF HYDRODYNAMIC PERFORMANCE OF 3-D WIG BY IBEM
Authors: Bal S
Published: December 2021

The hydrodynamic performance of three-dimensional WIG (Wing-In-Ground) vehicle moving with a constant speed above free water surface has been predicted by an Iterative Boundary Element Method (IBEM). IBEM originally developed for 3-D hydrofoils moving under free surface has been modified and extended to 3-D WIGs moving above free water surface. The integral equation based on Green's theorem can be divided into two parts: (1) the wing part, (2) free surface part. These two problems are solved separately, with the effects of one on the other being accounted for in an iterative manner. Both the wing part including the wake surface and the free surface part have been modelled with constant strength dipole and source panels. The effects of Froude number, the height of the hydrofoil from free surface, the sweep, dihedral and anhedral angles on the lift and drag coefficients are discussed for swept and V-type WIGs.
COUPLED RANSE AND LIFTING LINE THEORY FOR ESTIMATION OF SHIP PROPULSION FACTORS
Authors: Ramesh K , Makkar I S
Published: December 2021

Advances in Computational Fluid Dynamics (CFD) techniques through the development of the Reynolds-Averaged Navier-Stokes Equations (RANSE) have assisted in estimation of resistance and propulsion characteristics of ships to a reasonable level of accuracy. The aim of this paper is to test and demonstrate the capabilities of the coupled RANSE and Lifting Line theory for undertaking ship resistance, propeller open-water and self-propulsion simulations. Further, parametric studies for generation of numerical propeller design sheets and optimisation of propulsive efficiency using the coupled simulation approach has been discussed. Commercial CFD solver “M/s Flowtech - Shipflow” has been used for the study. Initially, some benchmark experimental/numerical model results are validated with the results of the CFD simulations and then, further parametric analyses have been undertaken with the KRISO Container Ship and the KP505 Propeller. The numerical propeller series and the preliminary study methodology for optimization of location of propeller disc behind the ship’s hull are being proposed as an effective concept/feasibility design stage tool for estimation of ship propulsion characteristics.
EVALUATING KEY RISK FACTORS AFFECTING CARGO DAMAGES ON EXPORT OPERATIONS FOR CONTAINER CARRIERS IN TAIWAN
Authors: Tseng Wen-Jui , Ding Ji-Feng , Chen Yi-Chun
Published: December 2021

The main purpose of this article is to apply the Analytic Hierarchy Process (AHP) method to analyse key risk factors affecting cargo damages on export operations for container shipping carriers in Taiwan. Based on the literature and experts’ opinions, a hierarchical structure with three risk aspects and eleven risk factors was constructed. We then applied the AHP procedure and AHP experts’ questionnaires to evaluate the key risk factors. The empirical results showed that: (1) ‘Shipping proxy phase’ is the most important aspect affecting cargo damages on export operations for container shipping carriers in Taiwan. (2) In order of relative importance, the top four key risk factors are “shipper’s concealed items have not been reported,” “inappropriate cargo packaging,” “insecure fixation between the container and ship deck,” and “error in printed documents.” Furthermore, some recommendations concerning effective risk management strategies and advices are provided for container shipping carriers.
Protection of Microgrids
Authors: Ekanayake Janaka
Published: December 2021

The concept of microgrids goes back to the early years of the electricity industry although the systems then were not formally called microgrids. Today, two types of microgrids can be seen: independent and grid connected. The protection requirement of these two types differs as the protection needs of an independent microgrid are intended for protecting components and systems within the microgrid, whereas a grid connected microgrid demands both internal and external protection. The first part of this chapter is dedicated to independent microgrids. How protection devices such as residual current circuit breakers, miniature and moulded case circuit breakers, and surge protective devices should be selected for an example microgrid is discussed while referring to the relevant standards. In the next section, the protection of a grid connected microgrid is discussed. Particularly, micro-source protection, microgrid protection, loss of mains protection and fault ride-through requirements are discussed while referring to two commonly used distributed generator connection codes. An example with simulations carried out in the IPSA simulation platform was used to explain different protection requirements and calculation procedures. Finally, grounding requirements are discussed while referring to different interfacing transformer connections and voltage source inverter connections.
Phenomenon of primary and secondary animals within Iron Age deposits.
Authors: Bangsgaard Pernille , Pantmann Pernille
Published: December 2021

Animals are an integral part of deposition practices during the Danish Iron Age, and they probably represent the most common form of deposit within southern Scandinavia. Recently Gotfredsen published a volume on animals within Danish Iron Age grave contexts, but similarly comprehensive studies of animals from other contexts have not been attempted. Thus, classic sites such as Valmose, Bukkerup Langmose, and Sorte Muld still stand as the type sites for Danish Iron Age animal deposits. This article will demonstrate that there are good reasons for exploring deposits in more detail and investigate the significant variation in the treatment and quantities of sacrificial animal deposits. Furthermore, the current study has revealed a deposition pattern where a primary animal is often in the company of one or more secondary animals, the latter typically represented by a few bones. Salpetermosen Syd (MNS50010), south of Hillerød in North Zealand, Denmark is the main case study, but comparisons are made to several sites across Denmark where a similar deposition pattern has been observed.
Reconstructing the Gerdrup Grave –
Authors: Kastholm Ole , Margaryan Ashot
Published: December 2021

In 1981, a double burial from the 9th century was excavated at Gerdrup north of Roskilde. In the grave was a woman and a man. The woman was buried with a spear, while the man had apparently been killed before the burial. The tomb has been perceived as a ‘Master and Slave burial’, which was placed on a desolate site, perhaps because the buried were seen as pariahs. However, hitherto unpublished excavation data combined with new 14C analyzes show that the burial was part of a small multi-period burial site placed near a group of older burial mounds. Topographic analyses indicate that the burial was also located at a central ford, and thus had a prominent location. Not least, new DNA analyzes surprisingly show that the two buried have a parent-offspring relation; they are mother and son. The previous perception of the Gerdrup grave is thus challenged. This article intends to present the relevant excavation data and to discuss it in the light of the new analyzes.

Automatic emotion recognition in healthcare data using supervised machine learning
Authors: Azam Nazish , Ahmad Tauqir , Ul Haq Nazeef
Published: December 2021

Human feelings are fundamental to perceive the conduct and state of mind of an individual. A healthy emotional state is one significant highlight to improve personal satisfaction. On the other hand, bad emotional health can prompt social or psychological well-being issues. Recognizing or detecting feelings in online health care data gives important and helpful information regarding the emotional state of patients. To recognize or detection of patient’s emotion against a specific disease using text from online sources is a challenging task. In this paper, we propose a method for the automatic detection of patient’s emotions in healthcare data using supervised machine learning approaches. For this purpose, we created a new dataset named EmoHD, comprising of 4,202 text samples against eight disease classes and six emotion classes, gathered from different online resources. We used six different supervised machine learning models based on different feature engineering techniques. We also performed a detailed comparison of the chosen six machine learning algorithms using different feature vectors on our dataset. We achieved the highest 87% accuracy using MultiLayer Perceptron as compared to other state of the art models. Moreover, we use the emotional guidance scale to show that there is a link between negative emotion and psychological health issues. Our proposed work will be helpful to automatically detect a patient’s emotion during disease and to avoid extreme acts like suicide, mental disorders, or psychological health issues.

Foreflipper and hindflipper muscle reconstructions ofCryptoclidus eurymerusin comparison to functional analogues: introduction of a myological mechanism for flipper twisting
Authors: Krahl Anna , Witzel Ulrich
Published: December 2021

Background

Plesiosaurs, diapsid crown-group Sauropterygia, inhabited the oceans from the Late Triassic to the Late Cretaceous. Their most exceptional characteristic are four hydrofoil-like flippers. The question whether plesiosaurs employed their four flippers in underwater flight, rowing flight, or rowing has not been settled yet. Plesiosaur locomotory muscles have been reconstructed in the past, but neither the pelvic muscles nor the distal fore- and hindflipper musculature have been reconstructed entirely.

Methods

All plesiosaur locomotory muscles were reconstructed in order to find out whether it is possible to identify muscles that are necessary for underwater flight including those that enable flipper rotation and twisting. Flipper twisting has been proven by hydrodynamic studies to be necessary for efficient underwater flight. So,Cryptoclidus eurymerusfore- and hindflipper muscles and ligaments were reconstructed using the extant phylogenetic bracket (Testudines, Crocodylia, and Lepidosauria) and correlated with osteological features and checked for their functionality. Muscle functions were geometrically derived in relation to the glenoid and acetabulum position. Additionally, myology of functionally analogous Chelonioidea, Spheniscidae, Otariinae, and Cetacea is used to extract general myological adaptations of secondary aquatic tetrapods to inform the phylogenetically inferred muscle reconstructions.

Results

A total of 52 plesiosaur fore- and hindflipper muscles were reconstructed. Amongst these are flipper depressors, elevators, retractors, protractors, and rotators. These muscles enable a fore- and hindflipper downstroke and upstroke, the two sequences that represent an underwater flight flipper beat cycle. Additionally, other muscles were capable of twisting fore- and hindflippers along their length axis during down- and upstroke accordingly. A combination of these muscles that actively aid in flipper twisting and intermetacarpal/intermetatarsal and metacarpodigital/metatarsodigital ligament systems, that passively engage the successive digits, could have accomplished fore-and hindflipper length axis twisting in plesiosaurs that is essential for underwater flight. Furthermore, five muscles that could possibly actively adjust the flipper profiles for efficient underwater flight were found, too.
ANXA9 as a novel prognostic biomarker associated with immune infiltrates in gastric cancer
Authors: Zhang Tongtong , Yu Suyang , Zhao Shipeng
Published: December 2021

Background

Gastric cancer (GC) is the most prevalent malignancy among the digestive system tumors. Increasing evidence has revealed that lower mRNA expression of ANXA9 is associated with a poor prognosis in colorectal cancer. However, the role of ANXA9 in GC remains largely unknown.

Material and Methods

The Gene Expression Profiling Interactive Analysis (GEPIA) and Human Protein Atlas databases were used to investigate the expression of ANXA9 in GC, which was then validated in the four Gene Expression Omnibus (GEO) datasets. The diagnostic value of ANXA9 for GC patients was demonstrated using a receiver operating characteristic (ROC) curve. The correlation between ANXA9 expression and clinicopathological parameters was analyzed in The Cancer Genome Atlas (TCGA) and UALCAN databases. The Kaplan-Meier (K-M) survival curve was used to elucidate the relationship between ANXA9 expression and the survival time of GC patients. We then performed a gene set enrichment analysis (GSEA) to explore the biological functions of ANXA9. The relationship of ANXA9 expression and cancer immune infiltrates was analyzed using the Tumor Immune Estimation Resource (TIMER). In addition, the potential mechanism of ANXA9 in GC was investigated by analyzing its related genes.

Results

ANXA9 was significantly up-regulated in GC tissues and showed obvious diagnostic value. The expression of ANXA9 was related to the age, gender, grade, TP53 mutation, and histological subtype of GC patients. We also found that ANXA9 expression was associated with immune-related biological function. ANXA9 expression was also correlated with the infiltration level of CD8+ T cells, neutrophils, and dendritic cells in GC. Additionally, copy number variation (VNV) of ANXA9 occurred in GC patients. Function enrichment analyses revealed that ANXA9 plays a role in the GC progression by interacting with its related genes.

Conclusions

Our results provide strong evidence of ANXA9 expression as a prognostic indicator related to immune responses in GC.

Generally, vegetation change through the conversion of the world’s forest land to other uses has assumed an increasing scale due to the unprecedented growth of the human population which increases the demand for food and land. Some believed that decrease in vegetation in the area is attributed to oil exploration and exploitation activities only. This study aimed to find out the nature of the vegetation change in the region from 2000 to 2020. The data used was remotely sensed images as Enhanced Vegetation Index (EVI) observed by Terra-MODIS, downloaded via United States Geological Survey (USGS). The Simple Image Differencing was performed on two images (February 18, 2000 and February 18, 2020) using IDRISI software. The result shows that all the states in the Niger Delta region experience both positive and negative change in vegetation cover. The positive change was observed around locations where agricultural plantations exists and within urban areas followed by oil and gas exploration and exploitation that damage the natural forest cover, while negative change was observed around farms where intensive rainy season farming takes place. It was recommended that deforested areas in the region should be reclaimed by planting economic trees as plantation to enhance greenness and maintain balance of the ecosystem. If intensive farming is necessary, it should be practiced sustainably to save the environment.
