The Nations portal will have five main educational Hubs: Africa, Americas, Asia, Europe, and the Middle East..  There are many global challenge Hubs related to the Nations portal under development.

The following Nations challenge hubs have been started:

SDG 12 is to: “Ensure sustainable consumption and production patterns.”

One of the indicators is the number of national policy instruments to promote sustainable consumption and production patterns. Another one is global fossil fuel subsidies.

An increase in domestic recycling and a reduced reliance on the global plastic waste trade are other actions that might help meet the goal.

Africa is the world’s second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth’s total surface area and 20% of its land area. With 1.3 billion people as of 2018, it accounts for about 16% of the world’s human population.

Africa’s population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4.Despite a wide range of natural resources, Africa is the least wealthy continent per capita, in part due to geographic impediments legacies of European colonization in Africa and the Cold War,  predatory/neo-colonialistic activities by Western nations and China, and undemocratic rule and deleterious policies.

Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.

The Middle East is a geopolitical term that commonly refers to the region spanning the Levant, Arabian Peninsula, Anatolia (including modern Turkey and Cyprus), Egypt, Iran and Iraq. The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term “Middle East” has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia, but without the Caucasus and including all of Egypt, and not just the Sinai Peninsula.

Most Middle Eastern countries (13 out of 18) are part of the Arab world. The most populous countries in the region are Egypt, Iran, and Turkey, while Saudi Arabia is the largest Middle Eastern country by area. The history of the Middle East dates back to ancient times, with the geopolitical importance of the region being recognized for millennia. Several major religions have their origins in the Middle East, including Judaism, Christianity, and Islam.Arabs constitute the main socioethnic grouping in the region, followed by Turks, Persians, Kurds, Azeris, Copts, Jews, Assyrians, Iraqi Turkmen, and Greek Cypriots.
