Adaptive Greenhouse Design

Bram Vanthoor (HortiMaX)

The Dutch lose international market share in greenhouse construction because they only focus on glass greenhouses

Bram Vanthoor (HortiMaX)

Knowledge and skills of the grower and the labour are even more determining factors for profitability than the greenhouse design, materials and fittings

Peter Stradiot (Innogreen)

The level of high-tech of a greenhouse design depends on the market segment - or product price level - where the entrepreneur is focussing on

Marc Ruijs (WUR LEI)

Locally adapted intensive horticulture can help solving the world food challenge

The challenge

Between 2005 and 2055 25% to 66% more food needed for population growth and changing diet Depending on the population growth scenario

Issues:

Minimal need for external energy & management: good crop climate is natural consequence of greenhouse

structure and cover materials adapted to local climate

Optimal use of available resources: prediction models for cost-benefits analyses

Good management of crop and greenhouse: capacity building

Adequate crops: genetic selection of cultivars adapted to remaining local

constraints

Intensive horticultural production at low environmental impact is perfectly possible
