Food & Recipes

Every dish the Atlas publishes for Democratic Republic of the Congo, at national rather than community level — 12 in all: the staple a household eats daily, the dish the country names as its own, street food, what is cooked for a wedding or Eid, regional specialities and a drink. Quantities and method are given for every one, so these are recipes rather than descriptions, and each has a photograph from Wikimedia Commons. The Food page carries the whole continent, searchable by country and by ingredient.

Stories & Oral Literature

The Island KingdomsPolitical history

Idjwi, at 70 kilometres long, is the largest island in Lake Kivu and the second largest inland island in Africa. It has been divided between two Havu kingdoms since a nineteenth-century split, Ntambuka in the north and Rubenga in the south, each with its own mwami, drums and tombs. The island's isolation kept it comparatively out of the worst of the Congo wars — it has no road connection to anywhere and is reached only by boat — and it has absorbed displaced people from the mainland repeatedly.

Albinism on IdjwiMedical and social history

Idjwi has among the highest recorded prevalences of oculocutaneous albinism anywhere, attributed to a founder effect in a long-isolated and endogamous population. Researchers have documented rates far above the continental average. People with albinism in the Great Lakes region face acute danger from attacks driven by beliefs about their body parts, and Idjwi's community has organised — with Congolese and international support — around protection, sun-protection and schooling, in a context where the island's isolation is both a shield and a constraint on medical care.

The Lake That Could ExplodeNatural hazard

Lake Kivu holds enormous quantities of dissolved carbon dioxide and methane in its deep water, trapped by density stratification. A limnic eruption — of the kind that killed 1,700 people at Lake Nyos in Cameroon in 1986 — would be catastrophic for the two million people on its shores. Methane extraction for power generation has begun on the Rwandan side, which reduces the hazard and generates electricity, and Idjwi sits in the middle of the lake with no evacuation route.

Proverbs

The island hears the war and does not see it.

On Idjwi's isolation.

The lake is calm on top and holds its breath below.

A saying that acquired a new meaning when the gas was understood.

A child of the sun needs shade from his own village.

A saying used in the island's albinism advocacy.

Mythology & Spiritual Beliefs

Creation: Nnamahanga as the creator; Lyangombe and the kubandwa possession cult; the lake and its islands carrying named powers and prohibitions.

Beliefs: Kubandwa historically; royal ancestral observance at the tombs; Catholic Christianity dominant, with Pentecostal expansion; fishing prohibitions and observances at named landings.

Ancestors: Royal tombs on Idjwi are tended and the mwami's genealogy is recited at installation; lineage ancestors are addressed at homestead level.

Building techniques: Pole and mud with grass thatch, now brick and iron sheet; dugout and plank canoe building; the royal enclosure with reed fencing; woven granaries.

Village layout: Houses along paths above the landings with plots behind, the royal compounds on commanding ground, and the fishing beaches shared by clan.
