Agventure Ltd’s main focus is Conservation Agriculture.

Conservation Agriculture focuses on:
- Elimination or reduction of ploughing exercises which disrupt the soils natural processes.
- Preservation of soil = reduced erosion and water conservation.
- Increased use of rotational crops to break the cycle of disease.
- Focus on promoting and boosting biological activity and diversity.
- More opportunistic farming – fewer fixed dates and more season-based cropping decisions.

Rotational crops not only must be used, but they must become part of the economic cycle for the farm. If performed correctly, this can result in a lower cost of production and better long-term sustainability for the farming system.
Business units include:
- Input purchasing
- Sale of unprocessed crops
- Sale of part-processed crops
- Oilseed processing
- Retail
- The Center of Excellence for Crop Rotation is a not-for-profit department which focuses on building farmer capabilities within the wider farming community.

Hewn into a rocky hillside on the sprawling Borana Reserve in Laikipia, Kenya, Arijiju is an enchanting private family home that has been designed and constructed over a painstaking ten-year period and is now available for exclusive hire for groups of up to ten adults and 4 children. The calm and contemplative space takes inspiration from the Ethiopian churches of Lalibela that lie to the North, and a 12th century monastery in France. Arijiju boasts vaulted archways, stone passageways and a central landscaped courtyard, whilst its flat roofs planted with natural grasses and rough-hewn rock see it all but disappear into the untamed landscape.

Arijiju is home to five exquisite suites, three flanking the central courtyard and a further two nestled in the olive groves that surround, whilst a sixth ‘constellation suite’ is available for those nights too beautiful to sleep anywhere but under the stars. Elsewhere, a cavernous dining room, games room, cinema and well-equipped library are available for cooler nights.

Arijiju is not just a safari lodge but a health and wellness retreat too. The cuisine and fresh daily smoothies lend to the healthy lifestyle Arijiju supports. There is a spa, Hammam, gym, yoga deck, tennis court and squash court all inconspicuously blending into the valley, and all spa and beauty treatments are included in the modest rate. The owner is driven by conservation not commercial gain.


Borana Lodge is steeped in history and style. Located at the heart of Borana Conservancy, Borana Lodge is set against a beautiful hillside with an organic design and panoramic views throughout.

There are now over 95 black rhino and 84 white rhino on the Lewa-Borana landscape.
Since the introduction of Rhino, Borana Lodge has become the only lodge in Kenya to invest all retained earnings into conservation. This means that every night spent at Borana Lodge is invaluable to the conservation of the surrounding landscape, communities and wildlife.
Staying at Borana Lodge acts as a direct contribution to safeguarding the future of endangered wildlife in Kenya.
This truly is travelling with a purpose.
