WHY IS NIGERIA 🇳🇬 UNDERDEVELOPED?

It’s a fair question—and also a complex one. Nigeria isn’t “poor” in resources; in fact, it’s rich. The issue is a mix of historical, political, and economic factors that have slowed development over time.

1. Colonial legacy and structure
Nigeria was shaped during British colonial rule in Nigeria, where the economy was designed mainly to extract raw materials, not to build strong local industries. After independence, that structure remained.

2. Weak governance and corruption
Corruption has been a major issue. Large amounts of public money meant for infrastructure, healthcare, and education have been mismanaged or diverted. This weakens institutions and slows progress.

3. Overdependence on oil
Nigeria relies heavily on oil exports:
Oil brings in most government revenue
But it creates a “resource curse” problem
Other sectors like agriculture and manufacturing are neglected

This makes the economy unstable when oil prices fall.
4. Political instability and policy inconsistency
Frequent changes in leadership (military and civilian in the past) have led to:
Poor long-term planning
Policies that change too often
Lack of continuity in development projects

5. Security challenges
Groups like Boko Haram and widespread banditry/kidnapping:
Discourage investment
Destroy infrastructure
Disrupt education and farming

6. Rapid population growth
Nigeria has one of the fastest-growing populations in the world:
More pressure on jobs, schools, and healthcare
Government struggles to keep up with demand

7. Poor infrastructure
Limited electricity, bad roads, and weak transport systems make business expensive and inefficient.

8. Education and human capital gaps
While there are many talented people, the system struggles with:
Underfunded schools
Brain drain (skilled people leaving the country)
⚖️ Important balance

Nigeria is not without progress:
It has one of Africa’s largest economies
Strong entrepreneurship (especially tech, entertainment like Nollywood)
Huge human potential
Bottom line
Tom's Nugget
Nigeria’s underdevelopment is not due to lack of resources—but mainly how resources and systems have been managed over time.

History of the Strait of Hormuz
The Strait of Hormuz has been one of the world’s most important sea routes for thousands of years.
1) Ancient times
Used by ancient traders from Mesopotamia, Persia, India, and East Africa.
Key route for trading spices, silk, pearls, gold, and incense.
Important for early Arab and Persian maritime trade.
2) Medieval period
Controlled at different times by Persian empires and Arab kingdoms.
Became a key link between Asia, the Middle East, and Europe.
Famous trading ports developed along the coast.
3) Portuguese period (1507–1650)
The Portuguese Empire captured and controlled parts of the area.
They built forts and naval bases to dominate Indian Ocean trade.
Their control later ended due to Persian and Arab resistance.
4) British influence (1800s–early 1900s)
The British Empire protected shipping routes to India.
Increased naval presence to secure trade and communication lines.
5) Modern era (1900s–present)
Became globally critical due to oil and gas exports.
Central to many political tensions, especially involving Iran, Gulf countries, and Western powers.
Any disruption here affects global energy prices and world economy.
Simple summary:
For centuries, the Strait of Hormuz has been a strategic gateway connecting East and West, and today it is vital for global oil transport 🌍.

As President Tinubu signs the Electoral Act Amendment Bill 2026 into Law, citizens should note the following 7 major changes:

1. Voter registration: Documents required for voter registration are narrowed to 3 : a birth certificate, a Nigerian passport and a National Identification Number (NIN).

2. Downloadable voter card: Voters can download their voter card from INEC’s website.

3. Electronic transmission of results: Electronic transmission to IReV is compulsory.
However, if it fails, the physical result sheet (EC8A) becomes the primary source of collation and results declaration.

4. Mode of party primary election: The new bill adopts direct primaries and consensus as the only methods for political parties to nominate candidates.

5. Disbursement of funds to INEC: Election funds must be released to INEC at least 6 months before the general election. Previously: 12 months.

6. Deadline for submission of candidates’ list: Political parties must submit candidates 120 days before election day. Previously: 180 days

7. INEC’s final list of candidates; INEC must publish candidates' list 60 days before the election. Previously: 150 days.

Except for the provisor in Section 60 (3) which holds that upon network failure inhibiting electronic transmission; form EC8A becomes the primary mode of collation and result transmission . I’ll say the other amendments are fine.

At this juncture, the National Assembly has done its part. The Presidency too.

Now its left for every citizens to channel their attention to INEC and ensure it:

• Strictly complies with the law and equally treats all political parties and candidates.

• Deploys technology effectively for voter accreditation, result transmission, and real-time transparency.

• Guarantees timely logistics and efficient distribution of election materials.

• Protects the integrity of the voters’ register and prevents manipulation.

• Works closely with security agencies to ensure peaceful, violence-free polls.

• Promptly uploads and publish results to strengthen public trust.

Ultimately, Nigerians are the true government and every institution actually is accountable to the people.

The people MUST follow the money and question every kobo of the ₦873 billion to be released for the 2027 elections.

Question the quality of BVAS machines.

Insist on smarter softwares for BVAS and IREV systems.

Demand a partnership with a network provider e.g. Starlink for a sure nationwide service for the election week. Coverage over the 177,000 polling unit should cost more than ₦65billion.

Lastly, laws are dynamic not absolute. They are made by men to serve mankind and can ve challenged in the courts of law. Therefore Citizens who are dissatisfied with any or all of the amendments can challenge the Electoral Act 2026 via a judicial action.

ISO NDT CAREER PATHWAYS

Got it—you’re asking about ISO NDT (not ASNT). That’s a slightly different world, so let’s clear it up cleanly.
What “ISO NDT” usually means People are almost always referring to ISO 9712 certification. It’s the international NDT certification system, widely used outside the U.S. (Europe, Middle East, Asia, Africa).
So:
ASNT → U.S.-centric (employer-based certification)
ISO 9712 → International, third-party certified, portable
Certification structure (ISO 9712)
Level 1 – Performs tests under supervision
Level 2 – Sets up equipment, interprets results, writes reports
Level 3 – Procedures, standards, audits, training oversight
Methods are the same as ASNT: UT, RT, MT, PT, VT (plus advanced UT like PAUT, TOFD)
Why people prefer ISO 9712
🌍 Globally recognized — easier to work abroad
🧾 Independent certification — not tied to one employer
🏗️ Often required for EPC projects, oil & gas, and large international contracts
📦 Your cert stays valid even if you change companies
Downsides
💸 Training + exams can be expensive
📅 Recertification is strict (time + exams)
🧠 Exams are theory-heavy
Some U.S. companies still prefer ASNT
Career outlook Very solid if you:
Want international or offshore work
Are in oil & gas, power plants, fabrication, pipelines
Plan to specialize (PAUT/TOFD especially)
Typical career path VT → MT/PT → UT → PAUT/TOFD → Level 3 (eventually)
Pay Varies wildly by country, but ISO-certified techs often earn:
Competitive local wages
Premium rates on international projects
Higher pay for shutdowns and advanced UT
Big question for you Are you looking at:
Working outside your country?
Oil & gas / pipelines?
Just starting NDT, or already certified in ASNT?
Your answer changes whether ISO 9712 is the best move—or just an extra badge.
