Agriculture in Namibia: Need for Growth
The development of agricultural engineering in Namibia can be traced back to the early 20th century, during the time when the country was under South African rule. During this period, the emphasis was placed on the development of large-scale commercial farms, primarily for the purpose of exporting. Following independence in 1990, the Namibian government placed a high importance on agricultural development, acknowledging its significant potential for both economic growth and ensuring food security. The establishment of the Ministry of Agriculture, Water and Forestry in 1991 was a major step forward in the progress of agricultural engineering in the country.
Agricultural engineering is a field that brings together principles from engineering, agriculture, and environmental science to create sustainable agricultural systems. As agricultural engineers, Lithon's responsibility is to create, enhance, and oversee agricultural infrastructure, machinery, and equipment to maximise crop production, minimise waste, and protect the environment.
Namibia's agricultural industry is one of the country's main economic drivers, making up around 5% of its GDP (World Bank, 2020). The industry encounters various challenges:
- Water scarcity: Given Namibia's status as one of the driest nations on Earth, agricultural engineering must prioritise water conservation.
- Climate change has a significant impact on crop yields and agricultural productivity, as rising temperatures and shifting rainfall patterns come into play.
- Food security is a crucial concern for Namibia, as the country heavily depends on imports to meet its food demands. Prioritising local food production is absolutely essential.
- Namibia's agricultural industry is interconnected with the broader African agricultural landscape, sharing common challenges. The Comprehensive Africa Agriculture Development Programme (CAADP) of the African Union is dedicated to enhancing agricultural productivity and ensuring food security throughout the continent.
- Namibia's agricultural industry has strong ties to global markets, exporting a variety of products such as beef, grapes, and cotton. The country is also a participant in the World Trade Organization's (WTO) Agreement on Agriculture, which seeks to foster equitable trade practices in the agricultural sector.
The sector is marked by a combination of subsistence farming and commercial agriculture, with livestock farming, especially cattle and goats, being the dominant activity. The northern regions have a higher concentration of crop production, particularly of maize, millet, and sorghum, due to the relatively higher rainfall in those areas.
Agricultural engineers play an important role in Namibia's sustainable development and food production. Water is the lifeblood of Namibia's agricultural industry, accounting for 70% of the country's water usage. Efficient irrigation systems and water management practices ensure food security, promote economic growth, and maintain the sector's contribution to GDP, especially in the face of climate change and water scarcity challenges.

Mashare Irrigation Scheme Phase
The Mashare Irrigation Scheme Phase is a project of great importance, focused on improving agricultural productivity by implementing effective water management techniques. Situated in the Kavango East Region, this project harnesses water from the Kavango River to efficiently irrigate extensive areas of land. The project entails the implementation of innovative irrigation systems, including centre pivots and drip irrigation, which are engineered to optimise water usage and enhance crop productivity.
Lithon was instrumental in the design and implementation of the irrigation infrastructure for this project. Our technical knowledge and problem-solving skills enabled us to customise the system to fit the specific local conditions, tackling issues like fluctuating water availability and different soil types. The scheme has effectively boosted agricultural output, ensuring a dependable source of income for local farmers and making a significant contribution to regional food security.
Ndonga-Linena Irrigation Scheme
The Ndonga-Linena Irrigation Scheme, situated in the Kavango East Region, serves as a prime illustration of a successful application of agricultural engineering. This project is centred around the cultivation of high-value crops such as maize, wheat, and horticultural products. The scheme encompasses a vast expanse of around 500 hectares, employing cutting-edge irrigation technologies to maximise water efficiency.
Lithon's role in this project involved the meticulous planning, precise design, and meticulous supervision of the infrastructure and irrigation systems. The company's approach incorporated sustainable practices, prioritising environmental conservation while optimising agricultural productivity. The Ndonga-Linena scheme's success has served as a blueprint for irrigation projects in Namibia, emphasising the crucial role of engineering expertise in agricultural development.
Agricultural engineering is a cornerstone of Namibia's efforts to enhance agricultural productivity, ensure food security, and promote sustainable farming practices. Lithon will continue to be a crucial player in this sector, providing extensive knowledge in irrigation, soil conservation, and infrastructure development. Our strategic approach ensures that our contribution to the sector remains competitive and equipped to meet future demands.
Frequently Asked Questions
How much land is used for agriculture in Namibia?
The percentage of agricultural land in Namibia was recorded at 47.14% in 2021, as reported by the World Bank's collection of development indicators, which is sourced from officially recognised data.
What are the water sources in Namibia?
Namibia relies on various sources of water, including border rivers, dams on ephemeral rivers, ground water, fountains, seawater desalination, and recycled water.
What is the primary source for water in Namibia?
The primary sources of irrigation water include groundwater from wells, surface water, drainage ponds, rainwater, and municipal water. Drilled wells serve as a reliable source of water for numerous greenhouse operations. However, it's important to note that the water yield from these wells is typically limited.
What are the reasons for the scarcity of water in Namibia?
Namibia's geographical and climatic features contribute to its significant susceptibility to water scarcity. The country's dry climate, along with unpredictable rainfall patterns, has resulted in a severe scarcity of water. In addition, the challenges mentioned above have been further intensified by the effects of climate change.
Based on data from the Ministry of Agriculture Water and Land Reform, it is evident that the country's water demand is increasing due to various industries such as mining and energy. The projections indicate that this demand will almost double by 2025, reaching a staggering 772 million cubic metres per year by 2030.
