  • The success of our projects relies on close, partner-like cooperation with our customers, for success is always a team achievement.

Help for self-help with ecological vegetable cultivation With Abalimi to basic income and quality of life in the township

Abalimi (Xhosa: ‘The cultivator’) is a community organisation which, primarily in the townships east of Capetown has helped several thousand people, the majority of them women, to create and cultivate home gardens and larger community gardens under difficult conditions. The cultivation projects secure a basic income and at the same time ensure sustainable ecological development of the townships.

Garten und Wasserleitung

This is how ABALIMI works:

  • Abalimi offers training for farmers. These include topics such as building healthy soil, composting, producing seed and seedlings, as well as bookkeeping and marketing.
  • Abalimi provides subsidised seed, seedlings and compost in two garden centres
  • Abalimi ensures there is a functioning infrastructure for watering and soil improvement (sandy soil is improved with ‘lasagne beds’)
  • Abalimi enables for the produce which extends beyond one’s own needs, market access via ‘Harvest of hope’. The vegetables are purchased, collected and packed as organic vegetables to be sold in well-off parts of Capetown.

Our donations are invested directly (climate compensation) in this ‘vegetable growth’ and/or in trainings and education for the farmers.

The dry weather in summer 2017-18 made the situation worse for ABALIMI’s small farmers. The construction of a well in the Moya We Khaya garden in Khayelitsha was planned and supported financially.

At the end of February 2019, the well was finally put into service; it provides sufficient water to sustain the garden, the farmers will soon be able to deliver vegetables for ‘Harvest of hope’ once again.
