Coloniality of Infrastructure
October 2021

Since the 1950s, various petroleum and gas wells have been dug on African Saharan soils. Thousands of kilometers of pipelines have been built on African and European soils and under their waters to transport extracted resources from African to European countries. These Saharan resources contributed to the establishment of a new world (dis)order in the aftermath of the Second World War. It all started in in 1956, January, about fifteen months after the outbreak of the Algerian Revolution, or the Algerian War of Independence (1954–1962), when oil spouted for the first time in Edejeleh, in the In Amenas District, in the Algerian Sahara, under French colonial rule, near the border with Libya.1 In July of that same year, a major oil field was uncovered in Hassi Messaoud, in Ouargla Province, eastern colonized Algeria, at about 895 kilometers southeast of Ouargla. And in November, the French colonial regime found what was one of the largest gas fields in the world in Hassi R’Mel, in Laghouat Province, about 400 kilometers south of Algiers and sixty kilometers northwest of Ghardaïa.2 The extraction of natural gas began in 1961, and in 1964 the newly independent Algeria became the first country to export Liquefied Natural Gas (LNG). Today, extracted natural gas supplies onshore and offshore pipelines, including the Maghreb-Europe Gas (MEG) Pipeline (via Morocco to Spain, where it is connected with Spanish and Portuguese gas grids); the Trans-Mediterranean (TransMed) Pipeline (via Tunisia to Sicily and then to Italy and Slovenia), and Medgaz (through the Mediterranean Sea to Spain).3

France’s search for natural resources in the Sahara under colonial rule dates back to 1945, with the establishment of the Bureau de recherches du pétrole (BRP, or Petroleum Research Office), followed by the creation of the Société nationale de recherche et d’exploitation des pétroles en Algérie (SN Repal, or National Company for the Research and Exploitation of Petroleum in Algeria). At the time of their explorations, Algeria’s Sahara was known as the Territoires du Sud Algérien (Algeria’s Southern Territories), which had been annexed to the French empire in 1902.4 These territories had an autonomous budget and were under a military administration. Over the course of the colonization of the Sahara, French colonial administrators and officers conducted violent military operations called the “pénétration au Sahara” (Saharan penetration), “pacification du Sahara” (Saharan pacification), or “pénétration pacifique” (peaceful penetration), to collect data about the geography, geology, meteorology, botany, zoology, resources, buildings, and ethnography of the region. These operations sought to create a territorial connection between France’s colonized territories in northern, central, and western Africa in order to enlarge its empire and impede British endeavors to link their colonized territories, including Egypt, Sudan, and Nigeria.5

The year 1956 marked not only France’s detection of oil and gas in the Algerian colonized Sahara, but also negotiations for the creation of the European Economic Community (EEC), which began at the Château of Val-Duchesse in Brussels. In March of the following year, Belgium, France, Italy, Luxemburg, the Netherlands, and West Germany signed both the Treaty of Rome, which established the EEC (which has evolved into what is now the European Union), and the Euratom Treaty, which established the European Atomic Energy Community. At this time, Algeria’s territory was an integral part of France, and therefore colonized Algeria—France’s Overseas Territory—became part of the EEC.6 This colonial condition offered Europe, specifically France, the opportunity to develop and advocate for European oil and gas companies and industries geographically close to Europe. It also reset the geopolitical landscape and cartography of hydrocarbon capitals and businesses, which were then concentrated in the Soviet Union, the Middle East, North and South Americas.

While the six European leaders were preparing the establishment of the EEC, the brutal Battle of Algiers was unfolding in the Casbah of Algiers. Conducted by one of the most violent French military commanders, the Battle sought to eliminate Algerian liberation fighters from Algiers who carried out a campaign of urban warfare between September 1956 and September 1957. The French army used torture, forced disappearances, and illegal executions, and was featured in the famous 1966 Algerian-Italian movie The Battle of Algiers, directed by Gillo Pontecorvo. The French officers secretly transferred these methods to North and South Americas during the 1960s.7 Since the invasion of Iraq in 2003, however, the United States and other governments and armies have overtly expressed their interest in French military practices deployed in the Battle of Algiers, and in the ways in which the French army had created, learned from, integrated, and enforced counterrevolutionary measures.8 France’s determination to use any means necessary to keep Algeria under colonial rule is intrinsically associated with the detection of large reserves of hydrocarbons in the Algerian Sahara and its desire to include those resources in the EEC.

In order to exploit its various recourses and oversee them, the French authorities attempted to separate the Sahara from the rest of Algeria. To do this, the French colonial authorities approved the creation of the Organisation commune des régions sahariennes (OCRS) in January 1957.9 The objectives of the OCRS involved “the development, the economic expansion and the social promotion of the Saharan zones of the French Republic, and in the management of which Algeria, Sudan [today Mali,] Niger and Chad participate.”10 This entailed a French trans-Saharan organization being tasked with the development of oil and gas industries and the construction of its necessary infrastructure, including extraction facilities, research centers, and transportation systems. With the promise of creating employment opportunities, the French colonial OCRS redrew the map of the French empire, further dividing already divided territories and populations. In so doing, the French colonial regime established an “autonomous” African Saharan enclosure, separated—politically and juridically—from the rest of the African continent and directly attached to France, and thereby to the EEC.

The establishment of the OCRS was followed by the creation of the French Minister of the Sahara in June 1957. In his 1957 report “L’infrastructure de départ du Sahara et de l’Organisation Commune des Régions Sahariennes (O.C.R.S.)” (“The Initial Infrastructure of the Sahara and the Common Organization of the Saharan Regions (O.C.R.S.)”), Yvan du Jonchay—a French naval officer, economist, and geographer, who led one of the economic missions of the French city of Lyon in the Algerian Sahara—stated that: “the management of the O.C.R.S. is still rather unclear, since the very name of economic organization excludes, in principle at least, a political action.”11 In other words, the absence of terms such as “French,” “European,” “Algerian,” “African,” or “Economic” from the very appellation of the OCRS (Common Organization of the Saharan Regions) was strategic. This allowed the French authorities to create a pseudo-autonomous colonized territory, a French enclave, within Saharan regions, without announcing it. One could also suggest that the presence of the term “common” epitomized that obscurity and incite to wonder if these regions—their resources and populations—are to be deemed as “common” to Africans, French people, Europeans, or to other nations or businesses. Are the OCRS “common” to people and compagnies in Algeria, Chad, France, Mali, and Niger, or for the “common” good and interests of all?

France was reluctant to make Saharan investments, capitals, and profits “common” and to share them with its European counterparts—not to mention with its colonized territories and departments. Jean-Michel de Lattre, a French lawyer and Delegate General of the Association eurafricaine minière et industrielle (Euro-African Mining and Industrial Association), commented on the question of the participation of “foreign companies” (i.e. non-French stakeholders) in the search for and exploitation of hydrocarbons in the Sahara. He argued in 1957 that:

some circles, voluntarily or involuntarily, wanted to make people believe that there was a maneuver of a potential seizure of the wealth of the Saharan subsoil by foreign companies. In the name of a “vigilant and enlightened nationalism” they wanted to advocate a policy, that of “France alone.” This is yet another of those “false problems” that pave the way for the development of the Sahara.12

Citing the 1956 Suez Crisis and the political pressures from the United Nations, the Soviet Union, and the United States over France, Israel, and the United Kingdom to withdraw their military troops from the Suez Canal, de Lattre claimed that: “In the current state of the international balance of power, France cannot claim to exploit world-class deposits on its own without provoking dangerous reactions for its foreign policy or its financial freedom.”13 Until the dissolution of the OCRS in May 1963, about a year after Algeria gained its independence from France, France did its best to prevent the involvement of African, European, and other players.

Over the six years of its existence, the OCRS built various new extractive settlements, airports, hospitals, roads, pipelines, and other infrastructure that are still in use today. Along with the construction of extractive infrastructure and transportation systems, two nuclear research and firing centers were built: the Centre saharien d’expérimentations militaires (CSEM, or Saharan Center for Military Experiments) in Reggane, approximately 1,150 kilometers south of Algiers, and the Centre d’expérimentations militaires des oasis (CEMO, or the Center of Military Tests of Oases) in In Ecker, about 600 kilometers south-east of Reggane.14 In the early morning hours of February 13, 1960, France’s first atomic bomb was successfully detonated in Reggane, in the Sahara Desert of Tanezrouft, in southern Algeria. From February 1960—about five years after the outbreak of the Algerian Revolution and four years after the first exploitation of Algerian oil—to February 1966—about four years after Algeria’s independence—France detonated seventeen nuclear bombs in the Algerian Sahara and tested other nuclear technologies and weapons.

The nuclear centers built in the Sahara included housing units, warehouses, barracks, camps, offices, laboratories, workshops, a hospital, sports facilities, a swimming pool, water towers, an aerodrome, detection and decontamination centers, material, ammunition and fuel depots, and technical premises.15 When the French colonial civil and military authorities left Reggane and In Ecker in 1966 to continue their nuclear program in the Moruroa and Fangataufa atolls in the Pacific, they dug immense holes and buried contaminated engines, equipment, objects, and materials in the Sahara, covering them with contaminated soil and sands. Over the years, the winds and populations of the Sahara have uncovered and unearthed these toxic remains and debris.16 France’s toxicity—which severely damaged and contaminated human, animal, vegetal, and mineral lives as well as their surrounding environments—was put on display.

In February 2021, social media and European newspapers published photographs of the “soft milky-yellow light” and “the beautiful yellow ochre skies of Europe.” This “beautiful” color of parts of southern and central Europe was caused by sand particles and dust from the Sahara. According to weather services, the wind conditions in the Saharan regions of Algeria, Mali, and Mauritania forced sand two to five kilometers up into the sky before it was blown towards Europe via southerly winds. As a Euronews article from March 1, 2021, titled “Irony as Saharan Dust Returns Radiations from French Nuclear Tests in 1960s,” claims: “Dust from the Sahara Desert blown north by strong winds to France did not only bring stunning light and sunsets. It also carried abnormal levels of radiation.”17 The specters of France’s colonial toxification of the desert are now haunting people across Europe, while the pipelines and other extractive infrastructure continue to supply consumers in Europe and elsewhere.

The three northern departments of Algiers, Constantine, and Oran were proclaimed as integral part of France in 1848. France’s expansion into the Sahara Desert started in 1844 with the arrival of French soldiers in Biskra, a town located in the Ziban region at the edge of the desert.
