Gezira Scheme

Gezira Scheme. It is one of the world's largest irrigation projects, established during the Anglo-Egyptian condominium period. Located on the fertile clay plain between the Blue Nile and White Nile south of Khartoum, its primary purpose was the large-scale cultivation of cotton for export. The scheme transformed the regional economy and became a cornerstone of the national economy, involving complex systems of canals, tenant farmers, and centralized management.

History

The concept for large-scale irrigation in the Gezira region was first seriously proposed following the 1899 report by Sir William Garstin. Initial experiments were conducted by the Sudan Plantations Syndicate after the completion of the Sennar Dam in 1925, which provided the necessary water control. The scheme officially began operations that year under the oversight of the British colonial administration, with significant financial backing from entities like the Empire Cotton Growing Corporation. It expanded considerably after World War II, and following Sudanese independence in 1956, management was transferred to the newly formed Sudan Gezira Board. The project later inspired other agricultural ventures in the region, such as the Rahad Scheme and the New Halfa Scheme.

Geography and infrastructure

The scheme occupies over 2.5 million acres of land in the Gezira and neighboring Manaqil area, situated on a vast plain between the two Niles. Its hydraulic heart is the Sennar Dam on the Blue Nile, which stores water for the annual flood irrigation cycle. A vast and intricate network of primary canals, including the major Main Gezira Canal, distributes water to smaller channels across the cultivated area. Key administrative and service centers developed within the scheme include the city of Wad Madani, which became the capital of Al Jazirah State. The infrastructure also encompasses numerous pumping stations, drainage ditches, and railway lines connecting to Port Sudan on the Red Sea.

Agricultural production and economy

For decades, the scheme's economic mainstay was the production of high-quality long-staple cotton, primarily for export markets in Europe and Asia. The cultivation followed a rigid crop rotation system mandated by management, which also included sorghum (dura), wheat, and groundnuts for local consumption and sale. The Sudan Gezira Board acted as the central marketing and procurement agency, selling the cotton through auctions in London and later Khartoum. Revenue was divided according to a pre-defined formula among the government, the board, and the tenant farmers. While cotton dominance has waned, the scheme remains a vital producer of sorghum and vegetables for Sudan.

Social and environmental impact

The scheme created a unique social structure, bringing together a large population of tenant farmers from various groups including the Ja'alin and West African migrants. It established planned villages with provided services such as schools, clinics, and mosques, significantly altering settlement patterns in the region. However, it also led to a dependency on centralized management and created social stratification. Environmentally, decades of irrigation have caused problems like soil salinity, waterlogging, and the spread of water-borne diseases such as malaria and schistosomiasis. The changing water flow regimes have also impacted ecosystems downstream in the Nile Basin.

Management and development

Management has evolved from the early private partnership with the Sudan Plantations Syndicate to full state control under the Sudan Gezira Board after independence. The board was responsible for all aspects, from water distribution and seed provision to crop marketing and revenue sharing. From the 1970s, the scheme faced challenges from aging infrastructure, political instability, and international price fluctuations for cotton. Development projects, often funded by the World Bank or Arab Fund for Economic and Social Development, aimed at rehabilitation and diversification. Recent decades have seen attempts at administrative reform and increased involvement of the private sector, amid the broader economic pressures facing Sudan.
