Agriculture Sector in Zambia

Adopting improved agricultural technology, such as fertilizer and seeds, can enhance productivity and financial viability for farmers. In Zambia, smallholder households using fertilizer increased to 58.4% in the 2018/2019 season, with most fertilizer used on maize fields. Copperbelt Province had the highest percentage (77%) of farmers using fertilizer.

However, despite increased fertilizer use, crop production dropped due to drought conditions in some regions. The Electronic Voucher -FISP Implementation, a digitalized input subsidy program, faced challenges in its implementation, leading to scaling down the program from 60% to 40% coverage. While it created opportunities for timely input delivery and enhanced rural economies, stakeholders advocated for full-scale implementation.

Improved seed use showed an upward trend over the years, with 66% of smallholder households using improved seed in the 2018/2019 season, particularly for maize. Increased private sector participation and government interventions contributed to this increase. The agricultural trade performance exhibited a declining surplus, with imports exceeding exports, impacting maize trade.

Prices for maize and mealie meal experienced an upward trend due to limited supply. Regarding sector performance, maize production declined by 16% in the 2018/2019 season due to drought conditions, but yields increased nationally. Private sector participation in maize marketing was active, and prices remained high throughout the season.

Wheat production was estimated at 207,772 MT, requiring over 200,000 MT of imports to fill the deficit.
Soya beans production was 281,389 MT, with prices fluctuating due to increased demand from processors.
Cotton production declined by 18% to 72,508.3 MT, with low productivity hindering growth.
Due to increased planting, mixed beans production increased by 12% to 58,705 MT, although yields dropped slightly.

Understanding Greenhouse Farming in Zambia

Greenhouse farming is growing crops in a controlled environment, protecting them from adverse weather conditions and pests. The system involves constructing structures made of glass or plastic that trap heat and light, creating a suitable microclimate for plant growth. Data shows greenhouse farming is gaining popularity in Zambia due to its numerous advantages. Farmers to extend the growing season, increasing crop yields. With better control over temperature, humidity, and irrigation, crops can grow throughout the year, reducing the impact of seasonal variations.

In Zambia, the adoption of greenhouse farming is gradually increasing, with a rise in the number of greenhouse structures being constructed. Accurate statistics indicate that most greenhouse farms focus on high-value vegetables and flowers, such as tomatoes, cucumbers, bell peppers, and roses. These crops fetch higher prices in the market, boosting farmers’ incomes and contributing to the country’s economy.

Moreover, greenhouse farming promotes efficient water use, allowing precise irrigation management and reducing water wastage. This is particularly important in regions prone to drought, where water conservation is crucial for sustainable agriculture. The introduction of greenhouse farming techniques has increased job opportunities in the agricultural sector. Farmers hire skilled labor to manage greenhouse operations, creating employment and income for local communities.

Benefits of Greenhouse Farming in Zambia

Increased Crop Yields: Greenhouse farming in Zambia has significantly increased crop yields compared to traditional open-field farming. Crops can thrive throughout the year with controlled environmental conditions, leading to higher productivity.

Extended Growing Seasons: Greenhouses allow farmers to extend growing seasons, enabling the cultivation of crops during adverse weather conditions. Reduces the crop failure and ensures a more consistent production supply.

Water Conservation: Greenhouse farming promotes efficient water usage through drip irrigation and recycling. This sustainable approach helps conserve water resources, especially in drought-prone regions.

Pest and Disease Control: Greenhouses offer better protection against pests and diseases by providing a controlled and enclosed environment. This reduces the need for chemical pesticides and promotes healthier, chemical-free produce.

Improved Crop Quality: The controlled environment in greenhouses allows for better management of nutrients, light, and temperature, resulting in higher-quality crops with enhanced taste, appearance, and nutritional value.

Optimal Space Utilization: Greenhouses maximize land use by enabling vertical farming and stackable growing systems. This is particularly beneficial in areas with limited arable land.

Job Creation: Greenhouse farming requires skilled labor for maintenance, monitoring, and crop management, leading to job opportunities and increased income for rural communities.

Climate Resilience: Greenhouse farming helps mitigate the impact of extreme weather events, making agriculture more resilient to climate change effects.

Reduced Dependency on Seasonal Crops: With greenhouses, farmers can grow non-traditional and high-value crops not limited to specific seasons, diversifying their income sources.

Higher Profitability: Due to increased yields and improved crop quality, greenhouse farming can lead to higher profitability for farmers, fostering economic growth in the agricultural sector.

Types of Greenhouses in Zambia and Choosing the Right One

Greenhouses in Zambia come in various types, including traditional, high tunnel, Venlo, and multi-span options. Each type caters to different scales of production and specific crop requirements. Traditional greenhouses suit small-scale farmers, while high tunnels offer cost-effective solutions for medium-scale growers.

Venlo greenhouses provide sophisticated control for commercial farmers, and multi-span structures are ideal for large-scale production. Choosing the right greenhouse depends on available space, budget, crop type, weather conditions, and automation needs. Seeking expert advice helps tailor the greenhouse to specific requirements, ensuring successful and sustainable agricultural practices.
