PUBLIC‐PRIVATE PARTNERSHIP SUPPORTING WOMEN‐DRIVEN 

POTATO SEED MULTIPLICATION IN THE LUMWANA CATCHMENT AREA NORTH‐WESTERN ZAMBIA

Chalwe A., S. Bwembya, and D. Subakanya

Page 2: Sess3 4 chalwe_th2_abs034

Background

• Potato is a high value crop largely grown by commercial farmers

• Interest is increasing among small‐scale farmers

• Increasing consumption demands in mine areas

• The market demands year‐round production  

Page 3: Sess3 4 chalwe_th2_abs034

Problem

• Farmers are incapacitated due to non‐availability of seed of improved varieties

• There is only one seed supplier in Zambia • Seed is imported from  RSA• The primary targets are member commercial farmers. 

Page 4: Sess3 4 chalwe_th2_abs034

Strategic intervention• Public‐Private Partnership: 

• To introduce to farmer groups a most preferred and highly marketed improved varieties of potato

• Provision of necessary skills on production

Implication

• Small‐scale production of potatoes in Lumwana catchment area is a feasible and highly profitable venture which has the potential to reduce poverty among women. 

• The returns on farmers’ labour, US$ 24.60 (ZMK 127.92) and US$ 19.12 (ZMK 99.45) day‐1 obtained from growing 0.25 ha of potatoes by Lukusa nkunde and Bukwasho women groups, respectively, can enable women to live far much above daily poverty datum line

Page 12: Sess3 4 chalwe_th2_abs034

Challenges

• Watering by hand is a labour‐tasking activity• Long distance to streams and uncontrolled quality of water

• Diseases due to uncontrolled movement of planting materials

• Lack of locally adapted high yielding varieties suitable for different end uses

• Storage of locally produced seed is difficult

Page 13: Sess3 4 chalwe_th2_abs034

Recommendations

• ZARI should start a breeding programme• Establish improved labour‐saving irrigation scheme. 

• The few promising individual farmers should be supported to take up potato seed production as a serious business. 

• There is need to introduce the low‐cost Diffused Light Stores (DLS) for seed potato tubers
