Mapping the Subsea Timberlands of the Mediterranean



Untitled 12

The debasement of P. Oceanica seagrass knolls is a significant worry since these marine ecosystems play a crucial job in the wellbeing and profitability of numerous Mediterranean marine natural surroundings. Seagrass and mapping are major devices for estimating the status and patterns of glades and their natural conditions (Topouzelis et al., 2018).

The Greek Non-Governmental Organization Archipelagos Institute of Marine Conservation, working from the islands of Samos and Lipsi, is focused on gathering spatial information around the Greek coast to create increasingly precise natural surroundings appropriation maps of P. oceanica so as to screen and secure these exceptionally important biological systems. Archipelagos lead marine research with different research vessels, including the 22-meter long Aegean Explorer. This vessel is furnished with a variety of logical instruments, including single-and multibeam sonar, structure scanner, biomass scanner just as a submerged camera equipped for arriving at a depth of 300 meters.

Mapping Seagrass Conveyance

The conveyance of Pacific oceanica is mapped by methods for remote detecting procedures, GIS, and sonar estimations in the field. One should learn ArcGis to know about the contribution for the remote detecting strategy is Sentinel-2A satellite symbolism. The satellite picture is pre-handled to manage essential rectifications of the obstructions that decide the light in the climate and water before determining any quantitative data on the sea-going territories that attention on seagrass (Traganos and Reinartz, 2018). The principle ventures here are environmental remedy, sun glimmer evacuation, and water segment amendment.

During the field tasks ground truth information about the seagrass knolls gathered. A DownScan sonar is introduced on an examination vessel and on the back of the kayak to get data about the ocean bottom. The sonar transducer transmits ultra-sound waves to the seafloor from which base morphology is determined. At the point when Pacific oceanica is available it happens on the sonar yield as a fluffiness over the seafloor. Waypoints are set for Pacific oceanica (P) or no P. oceanica (NP), which are utilized as preparing information during the picture arrangement procedure and exactness information during the precision evaluation.Untitled 13

Characterizing Seagrass Nearness or Nonattendance

Subsequent to adjusting the satellite picture, the pixels are classified to demonstrate Pacific oceanica nearness or nonappearance. Fundamental in most oceanic remote detecting considers is the way toward recognizing unmistakable spread or substrate types in the investigation zone on a satellite picture into reasonable classes, which is defined as remote detecting picture classification. In this system administered picture grouping is applied, in which the order is performed with ground truth information.

Four directed picture classifiers are investigated: Maximum Likelihood Classifier (MLC), Radial Support Vector Machine (SVM), Linear SVM and Random Forest (RF). Every one of these strategies is based alone numerical capacity. The decision for a strategy can be founded on various criteria, for example, picture goals, spatial scale and the ground truth informational collection. The systems are assessed on their exactness rate and Kappa Index. These parameters are inferred by methods for the precision waypoints and a Confusion Matrix (Cohen, 1960).

Looking at Picture Classifiers

The four picture arrangement strategies are performed for six distinct islands in the Southeast Aegean Sea, at three diverse spatial scales and with various waypoint densities to ideally investigate the capacity and execution of the methods. Figure 5 shows the seagrass appropriation around the island of Lipsi displayed by the four classifiers. Because of the impediments of satellite symbolism the appropriation is displayed till a bathymetry of 20 meters. The maps show critical contrasts in seagrass dissemination demonstrated by the four procedures.

RF and Radial SVM resulted in the most accurate maps (respectively 88% and 72%) for this study, even when the waypoint density is reduced. It can be noticed between these two that the seagrass pixels classified by RF are more randomly distributed than with Radial SVM, which clearly shows the function of these two techniques. MLC seems to overestimate the P. oceanica coverage since more than 50% of the NP points are modeled as P pixels. Linear SVM makes an extreme underestimation as 98% of the P points are modeled as NP pixels.

Concluding Remarks

The modeling of P. oceanica coverage around islands in the Southeast Aegean Sea resulted in highly accurate outputs modeled by RF and Radial SVM. The review has shown that each image classification technique consists of its own function and therefore delivers distinguishing outputs. The choice for a classification technique depends on different criteria, including spatial scale, image resolution, and the ground truth data set.

Simultaneously, the choice for a classification technique also strongly depends on the purpose and use of the final maps. For example, Archipelagos is committed to conserving the seagrass by using the maps to the government, local communities, ports, and fishermen to achieve legislation, protection, and awareness. A classifier that slightly overestimates is more likely to be selected in this case, than one that strongly underestimates. These classification purposes and applications should be kept in mind when investigating the techniques and the motives to select one. Because of these motivations, further contributions and efforts are required to investigate the assessment and applications of remote sensing image classification techniques.

Thabo Mbeki to lead Commonwealth observers for Nigerian elections



Thabo Mbeki

Former President of South Africa, H.E. Thabo Mbeki, will lead a team of Commonwealth election observers to Nigeria, which will be holding Africa’s largest democratic exercise later this month when it holds general elections on 25 February 2023.

Commonwealth Secretary-General, the Rt Hon Patricia Scotland KC, constituted the Commonwealth Observer Group following an invitation from Nigeria’s Independent National Electoral Commission.

As of January 2023, an estimated 93.4 million registered voters will have the right to cast ballots for presidential and national assembly candidates in 176,846 polling units across 774 local government areas.

Announcing the group, the Commonwealth Secretary-General said:

“The Commonwealth remains a committed and reliable partner in Nigeria’s continuing journey towards peaceful democratic governance. Since 1999, we have observed all six general elections in Nigeria and the deployment of this observer group is a testament to the Commonwealth’s enduring support for the promotion of the culture, processes and institutions of democracy in Nigeria.

“In accordance with the values and principles of the Commonwealth Charter, the work of the group seeks to promote transparency, strengthen democracy and the rule of law, and protect the right of the people of Nigeria to participate in credible, transparent and inclusive elections to shape their society.

“This month’s elections hold immense significance not just for Nigeria, but for the entire African continent and the wider democratic world. It is, therefore, essential that all stakeholders in Nigeria reaffirm their shared commitment to ensuring a peaceful election environment which is conducive to the free exercise of people’s franchise and in which fundamental freedoms and rights are respected.”

She also expressed her appreciation to President Mbeki for accepting her invitation to lead the group and to each observer for agreeing to undertake this important assignment on behalf of the Commonwealth.

The mandate of the group, which is independent and impartial, is to observe the preparations for the election, the polling, counting and the results process, and the overall electoral environment. The observers will assess the conduct of the process as a whole and, where appropriate, make recommendations for the strengthening of the electoral system in Nigeria.

Before deployment to different parts of Nigeria, the group will also have briefings with the electoral authorities, political parties, law enforcement agencies, the media and civil society groups representing women, youth and people with disabilities.

Upon completion of its assignment, the group will submit its recommendations in a report to the Commonwealth Secretary-General, who will forward it to the Government of Nigeria, the Independent National Electoral Commission, the leadership of political parties taking part in the elections and all Commonwealth governments. The report will be made public afterwards.

The Commonwealth Observer Group comprises 16 eminent persons from around the Commonwealth, including politicians, diplomats and experts in law, human rights, gender equality and election administration. The full team is listed below.

The observers will be in Nigeria from 18 February to 2 March 2023. They will be supported by a staff team from the Commonwealth Secretariat led by Joshua Setipa, Senior Director of the Strategy, Portfolio, Partnerships and Digital Division.

MTN Ghana Reviews Tariffs Upward




Scancom PLC (MTN Ghana) has announced an upward review of the tariffs of its products and services effective February 07, 2023.

The review is as result of two changes. Firstly, the implementation of the 2.5% statutory adjustment of VAT from 12.5% to 15% across all services. This will impact both Prepaid and Post-paid customers. Secondly, MTN Ghana is proceeding with a 15% average upward review of its mobile data tariffs which was originally announced in November 2022 and was subsequently put on hold. The increase in mobile data tariffs will impact both Pay Monthly and Pay-As-You-Go users. The review in mobile data bundle offers cover products available on the short codes 138 & 170, as well as on purchases through Electronic Voucher Distribution (EVD), MTN Pulse, and Data Zone except for XtraTime.  The data tariff increases do not apply to Fiber Broadband and Fixed Wireless Access (4G Router / Turbonet) customers.

With this review, voice users will receive less airtime due to the VAT implementation, and mobile data customers will receive less data bundle allocations for the same price purchased before the tariff increase was made.

The Chief Commercial Officer for MTN, Mr. Noel Kojo-Ganson, explained the impact by giving an example of how the new pricing will work. He said, following the review, a three cedis airtime purchase before the VAT increase, which previously gave customers 24.4 minutes will now give customers 23.9 minutes, whilst a three cedis data bundle which previously gave customers 471 MBs will now give customers 401 MBs.

Explaining the reason for the upward review of the Data Bundle prices, Mr. Noel Kojo-Ganson said the review was necessitated by the recent economic shifts leading to increasing cost of operations largely due to continuous increase in inflation. “These economic shifts have impacted us directly and for us to ensure we have the right balance for sustaining growth and investments into the network, we have had to consider price increases in various segments of our business.”

Mr. Kojo-Ganson added, “MTN recognises that we are in very tough times and would like to assure our customers that we will continue to offer them the convenience and flexibility in the purchase of data bundles at their desired price points via the MTN Flexi and Non-Expiry Bundles. Also, customers will continue to enjoy the 50% bonus incentive on mobile data purchases via MyMTN App & MoMo (valid for 7 days) for 4G customers”.

MTN remains committed to investing USD1 Billion by 2025 to continue its network expansion and improve the network experience for customers. In line with our Ambition 2025 strategy, our purpose is to lead digital solutions for Africa’s progress.
