Work and the economy in Ouesso

Economy

Ouésso functions as one of the four special economic zones in the Republic of the Congo. The town serves as the capital of the Sangha Department and operates as a designated center of commerce near the country's border with Cameroon.

A historical turning point for the local economy arrived in 2017 through a power purchase agreement with the Gezhouba Group. This accord led directly to the creation of the Liouesso Hydroelectric Power Station, establishing a reliable local energy source to replace previous deficits and power the municipality.

The economy of Ouésso relies primarily on mining, forestry, agriculture, and wood processing. Additionally, the area functions as a carbon negative zone, recording a carbon sink of -8.40 between 2001 and 2022. Economic expansion has also been supported by regional infrastructure investments, including port extensions funded by the Development Bank of the Central African States, which maintains a complex within the town.

02 · Food & culture

Food and everyday culture in Ouesso

Ouésso is a town and commune located in northern Republic of the Congo at the border of Cameroon. Lying on the Sangha River and surrounded by rainforest, it serves as the capital of the Sangha Department.

The culinary practices and food culture of Ouésso are historically tied to the surrounding rainforest and regional trade routes. In 1994, the population consumed 7,500 kilograms of bushmeat a week. The most sold animal in the local bushmeat market consisted of duikers, alongside gorillas, monkeys, and elephants. This meat supply was transported from Liouesso, a village situated southwest out of Ouésso, and frequently arrived via logging trucks traveling from Cameroon. The historical trade and consumption patterns operated under a local context where the bushmeat market lacked enforcement.

Ouesso, in brief

Overview of Ouesso

Ouesso is a town and commune located in the northern Republic of the Congo near the border of Cameroon. Situated on the Sangha River and surrounded by rainforest, it serves as the capital of the Sangha Department and the administrative center of the Ouesso District.

A historical turning point for the municipality's regional connectivity occurred with transportation infrastructure developments, including the construction of the Sangmelina-Ouésso Road. Completed in 2021 at a cost of US$354 million, the 321.5-kilometer route connected Ouesso directly to Cameroon and removed the need for ferries, an event marked by a ceremony attended by Emmanuel Nganou Djoumessi. Further infrastructural integration took place in 2023 when the Chinese National Development and Reform Commission built the Sangha Bridge and the Ouésso-Pokola Road, with a groundbreaking ceremony attended by president Denis Sassou Nguesso.

As one of the four special economic zones in the Republic of the Congo, the economy relies on mining, forestry, agriculture, and wood processing. Power for the town is supplied by the Liouesso Hydroelectric Power Station, which was established following a power purchase agreement in 2017 with the Gezhouba Group. Transportation networks also encompass the Ouésso Airport and the RN2 road connecting the town to Brazzaville, alongside a port extension finalized in 2015 with funding from the Development Bank of the Central African States.

The area has a tropical monsoon climate bordering on a tropical rainforest climate. Historical records for the locality include a 2010 parliamentary law protecting indigenous pygmy and Baka people and their land, which impacted local logging practices. Additionally, the town has been the site of judicial actions regarding wildlife enforcement, such as the 2016 sentencing of ivory dealer Hamadou Abbo and his accomplices Minda Xavier and Gonock Evounanga Edgard to five years in an Ouesso prison, as well as the 2018 arrest and subsequent legal proceedings involving poacher Guyvanho.

Notable figures born or connected to the region include French journalist, politician, and women's rights activist Jane Vialle, as well as Stéphane Maurice Bongho-Nouarra, a former prime minister of the Republic of the Congo. Official population figures recorded 75,095 residents during the country's latest census in 2023.
