Protected cultivation in the West-African country of Ghana wants to be more sustainable and internationally more competitive. The country for example knows a large shortage of tomatoes that are imported in large quantities from countries in the region. The DGIS-funded GhanaVeg project, in which Wageningen UR Greenhouse Horticulture and other parts of WUR participate, wants to improve productivity and create market opportunities for the Dutch and Ghanaian private sectors.

A quick scan has been conducted together with CDI (Wageningen UR Centre for Development and Innovation). Growers, suppliers, traders, researchers and governmental employees in various regions of the country have been visited. The country knows besides the humid south a much drier climate in the north. Protected cultivation is possible in all these regions (as is demonstrated by some growers), provide a number of limitations are removed. 

Protected cultivation still very limited in Ghana

Protected cultivation in Ghana is currently still very limited and the number of suppliers is small. The acreage is small and the levels of technology, logistics and knowledge are low. Cooling facilities are absent. Water is at many locations a problem during the dry season. Crop protection is almost fully chemical but not always effective. 

Capital-intensive cultivation

Positive are the high prices for many (fruit) vegetables which will make a more capital-intensive cultivation system profitable. There are commercial opportunities for suppliers of for example seed, crop protection agents, greenhouse constructions and installations, and logistical systems. Besides, heavy investments in training and growth advice, and must the organization of the horticultural sector be strengthened to benefit from the present opportunities.
