Strengthening resilience by restoration and enhancement of the Tomb of Askia in Gao (Mali)
The restoration and enhancement project of the Tomb of Askia in Gao aimed to strengthen the resilience of the world heritage property to climate change impacts, particularly water erosion caused by heavy rains and winds (The Harmattan), and silting through the utilization of traditional building practices, including community participation and the empowerment of local communities.
About the Tomb of Askia
The Tomb of Askia is located in the north of the town of Gao, Mali, near the River Niger, about 320 km east-southeast of Timbuktu and 1200 km from Bamako. The population of Gao is around 652.198. Women make up 50.3% of the population against 49.7% for men (2018).
The spectacular 17-m pyramidal structure of Le Tomb of Askia was built by Askia Mohamed, the Emperor of Songhai, in 1495, in his capital, Gao. The complex, including the pyramidal tomb, two flat-roofed mosque buildings (with two prayer spaces for men and women), the mosque cemetery (for descendants of Askia and the Haïdara) and the open-air assembly ground, was built when Gao became the capital of the Songhai Empire and after Askia Mohamed had returned from Mecca and made Islam the official religion of the empire. It is also a fine example of the monumental mud-building traditions of the West African Sahel. The pyramidal form of the tomb, its function as a central minaret, as well as the length and shape of the pieces of wood (made of strands) comprising the permanent scaffolding, give the Tomb of Askia its distinctive and unique architectural characteristics.
"The Tomb of Askia was inscribed on the World Heritage List under criteria (ii) (iii) and (iv) in 2004. “The Tomb of Askia is a magnificent example of how the local traditions have adapted to the exigences of Islam in creating an architectural structure unique across the West African Sahel."
In 2012, at the request of the State Party, due to the fact of armed conflict in the northern region of Mali and the seriousness of threats to the conservation of the Outstanding Universal Value of the Tomb of Askia, the World Heritage Committee decided to inscribe the property on the List of World Heritage in Danger (Decision 36 COM 7B.106).

Climate change-related impacts
Northern Mali is vulnerable to climate change externalities such as drought, floods, sandy winds and heavy rain in winter, which are of great danger to the buildings of this world heritage property, specifically its prayer space for men, which has been damaged repeatedly by water erosion. From the architectural perspective, the Tomb of Askia is characterised by rounded forms resulting in the regular renewal of the layer of plaster eroded each winter by the violent rains and has needed regular protection measures to avoid further damage. In August 2017, heavy rainfall led to the collapse of the necropolis's roof. (Source: Conservation issues presented to the World Heritage Committee in 2017)
Between 2012 and 2020, several State of Conservation reports were presented to the World Heritage Committee. Emergency UNESCO mission to Bamako and World Heritage Centre monitoring missions to Bamako were carried out in 2012. According to the 2012 monitoring mission’s report, the Tomb of Askia, specifically its necropolis of the men’s mosque, faced ongoing threats such as water erosion caused by heavy rains, lack of an updated Management and Conservation Plan, and risk of property collapse.
The World Heritage Committee (Decision 41 COM 7A.30) expressed its concern about the continuing degradation risks to the necropolis due to water erosion caused by heavy rains in August-September 2016. It encouraged “the State Party to request international assistance from the World Heritage Fund for the rehabilitation of this necropolis”.
In response to the Committee's decision, the State of Conservation report (2018) emphasised that several actions were undertaken to protect the necropolis from these impacts, including re-excavating rainwater drainage canals and developing water drainage systems along the enclosure wall. A 2018-2022 Management and Conservation Plan (including the risk management plan 2017) was developed in collaboration with the local community. Additionally, the State Party submitted and obtained approval for International Assistance in 2018, enabling repairs to the roof, maintenance of the pyramid tower, and regeneration of Hasu trees.

Traditional knowledge and practices/ Indigenous knowledge
The restoration was carried out by local masons and builders using traditional materials and methods widely practised in Gao, including the replacement of Hasu tree perches within the earthen structure to combat water erosion. From the traditional methods used, prepared mud mixtures (banco) enhance the quality of the mud bricks and withstand weather conditions such as wind and rain.
The mangrove forest on Manda and the islets within the Lamu harbour act as a natural defence against strong winds, tsunamis and advancing waves. Knowledge of weather patterns, sea movement and naturally safe areas during adverse atmospheric conditions, accumulated by local fishermen, farmers, and sailors over the centuries, provides important information which enhances the community's resilience during extreme weather or disasters.
Climate action solutions and strategies
The restoration and enhancement of the Tomb of Askia in the Gao project
Still on the World Heritage List in Danger, the Tomb, dating more than 500 years ago, constitutes an important religious site for the community. In 2018, despite the difficult security context in northern Mali and its impact on the security of Gao, there has been some progress made to protect the Tomb of Askia. The international assistance project was approved by the decision of the World Heritage Committee in 2018 with a budget of 24,585 USD. The project was implemented by local communities, the Cultural Mission in Gao and the National Directorate of Cultural Heritage (DNPC) of Mali under the supervision of the UNESCO Bureau of Bamako and the World Heritage Centre.
The restoration works carried out as part of this project aimed to repair the collapsed roof and reinforce the structures to prevent further collapse of the men's mosque of the Tomb. This involved replacing eucalyptus perches with Hasu trees on the pyramid tower and applying plaster.
- Regeneration of Hasu Trees: The perches of the now rare Hasu trees, called Maerua Cracifolia, known for their hardness and resilience, were instrumental in reinforcing the buildings. A forest officer was engaged in the regeneration of Hasu trees to provide the materials for long-term restoration. The regeneration of Hasu plants was a proactive measure to address the scarcity of Hasu perches required for the preservation of the property's Outstanding Universal Value.
- Minimise the impact of climate change on cultural heritage: A dedicated field was identified, techniques fenced, cleaned up and prepared by women to receive the plants grown in a nursery. The process of regenerating Hasu trees was implemented through staking (marking the future location of the plants), digging holes (40cm/60cm), and treating the holes. Then, the forestry expert developed and fenced the designated planting area before placing the Hasu trees in the holes, followed by the first watering. The field was irrigated and watched over by a guardian to maximise the progress. The engagement of women in the cleaning, preparation, and maintenance of the dedicated planting area for the regeneration of Hasu trees not only empowered them but also underscored the significance of inclusive gender participation in environmental initiatives.
- Integration of sustainable practices: The work plan, approved by the president of the masons' corporation, was to remove the eucalyptus poles from the pyramidal tower and replace them gradually with Hasu trees. The replacement of the eucalyptus poles was followed by plastering the pyramidal tower. The traditional method, widely practised in the city of Gao and mastered by the masons, was chosen. The entire structure was plastered using a pre-prepared mud mixture that enhances the quality of the mud bricks and withstands weather conditions such as wind and rain. The application of fine sand in the prayer space has strengthened the measures against water erosion. The project integrated sustainable practices to minimise climate change impacts on cultural heritage and enhance the site's overall resilience.
- Local Community Participation and Empowerment: The participation of the management committee, the corporation of local masons and the imam was instrumental in raising awareness, sharing responsibility, and ensuring cooperation. Using their local knowledge and techniques to reinforce the pyramidal tower as well as repair the roof and reinforce the pillars. Involving local communities and relevant stakeholders in decision-making and implementation has empowered them to contribute to climate-resilient solutions and ensure the sustainability of the restoration efforts. The participation of the population in the Hasu Nursery and plantation has also brought temporary income.
- Awareness-raising and educational activities: Radio awareness campaigns and the organisation of working sessions with technical teams have led to a better understanding of the restoration work and, more importantly, have mobilised local communities to safeguard the authenticity and integrity of the property. The project has demonstrated the importance of preserving traditional crafts and skills and their integration into the restoration, strengthening local entrepreneurship.
