Q1 – Encyclopaedia Britannica – Landlocked Country
https://www.britannica.com/topic/landlocked-country
Last accessed: 24.07.2026
"landlocked country, an independent sovereign state that does not have direct access to an ocean, such as the Atlantic, or to a sea that is not landlocked, such as the Mediterranean."
"Being a landlocked country prompts certain disadvantages which can curtail national income, such as the lack of seaports, coastal trading points, and a large-scale fishing industry."
"LLDCs have to cover considerable transport costs for merchandise to be sent to and received from overseas markets, thereby discouraging investment, decreasing their competitive edge, and isolating them from international trade. Seaborne trade must transit through other countries, which often involves dealing with inappropriate infrastructure and inconvenient border-crossing procedures."
"There are currently 44 landlocked countries."

"Landlocked developing countries continue to face structural challenges to accessing world markets."
"Landlocked countries often lag behind their maritime neighbours in overall development and external trade."
"In spite of technological improvements in transport, landlocked developing countries continue to face structural challenges to accessing world markets. As a result, landlocked countries often lag behind their maritime neighbours in overall development and external trade."
"High transportation costs typically place landlocked countries at a distinct disadvantage relative to their coastal neighbours when competing in global markets."
"Four such types of dependence are discussed: dependence on neighbours' infrastructure; dependence on sound cross-border political relations; dependence on neighbours' peace and stability; and dependence on neighbours' administrative practices."

"Landlocked developing countries sometimes pay transport costs three times the global average – and see that gap widen with each disruption."
"Rerouting ships on longer journeys has helped to absorb spare capacity."
"In 2024, global container charter rates were higher than in 2023. This stemmed particularly from increased TEU-mile demand from longer-voyage distances caused by ship rerouting and higher-than-expected growth in trade volumes."

"Between Q4 2025 and Q2 2026 (to 14 April), the average speed of the container vessel fleet dropped by 2.3%, from 15.58 to 15.22 knots, with the move concentrated entirely after 28 February."
"On 14 April, Alphaliner recorded an average of 15.18 knots, the lowest reading since March 2023."
"Container shipping speeds declined sharply in early 2026 as bunker prices surged, according to industry analysts Alphaliner."

"Access to maritime shipping and global participation in maritime trade is key to attracting global capital."
"Today, as much as 75% of international trade takes place over water due to the fuel efficiency of seaborne freight and worldwide dependency on water as a means of transportation."
"As energy consumption and transportation costs are concerned, maritime shipping is the cheapest form of transportation."
"The main concern is the ability of a landlocked country to reach inexpensive yet efficient transit systems and trade corridors."
"Ports positively impact local development."
"High quality port infrastructure and improved logistical performance had a positive impact on the national economy."
Q6 – HZ Containers – TEU im Seeverkehr
https://hz-containers.com/de/glossar/teu-im-seeverkehr/
Last accessed: 30.07.2026
"Warum ist TEU wichtig? TEU ermöglicht einen einfachen Vergleich der Kapazitäten verschiedener Containerschiffe und zeigt an, wie viele Container ein Schiff transportieren kann. Ein Schiff mit einer Kapazität von 1.000 TEU kann beispielsweise 1.000 Standardcontainer mit 20 Fuß Länge transportieren. Wenn ein anderes Schiff eine Kapazität von 2.000 TEU hat, kann es die doppelte Menge transportieren. Auf diese Weise vereinfacht TEU die Planung und Logistik im Seeverkehr und hilft Transportunternehmen, die Kapazitäten effizient zu verwalten."
"Was ist TEU? TEU ist die Abkürzung für „Twenty-foot Equivalent Unit“, was auf Deutsch zwanzig Fuß Äquivalenteinheit bedeutet. Es handelt sich um eine standardisierte Maßeinheit, die im Seetransport verwendet wird, um die Kapazität von Schiffen und Containern zu bestimmen. Ein TEU entspricht dem Volumen eines Standardcontainers mit einer Länge von etwa 20 Fuß, einer Breite von 8 Fuß und einer Höhe von 8 Fuß. Diese Größe ermöglicht den Transport verschiedener Güterarten und erleichtert die Handhabung in Häfen."
"Bedeutung von TEU im modernen Handel: In der heutigen globalisierten Welt ist der Warentransport über See ein entscheidender Aspekt des internationalen Handels. Container werden häufig verwendet, um alles von Elektronik bis hin zu Lebensmitteln zu transportieren – nicht nur zwischen Kontinenten, sondern auch innerhalb einzelner Länder. TEU hilft nicht nur Logistikunternehmen, sondern auch Handelspartnern, die Transportkapazitäten und -möglichkeiten besser zu verstehen, was für eine effiziente Planung und Steuerung von Lieferketten unerlässlich ist."

Prompt:
Create a clean educational infographic showing a truck transporting goods from a factory to a seaport and finally to consumers.
Display the transport cost above the truck at different stages of the journey.
At the beginning, show a lower transport cost using a green € symbol. Later in the journey, cross it out and replace it with a larger red €€€ symbol to illustrate increasing transport costs.
Use flat vector graphics, English labels, a white background and a presentation-style design.
