Fundación Dos Hermanas’s aim is to address the health and environmental crisis facing the world by integrating on its estancia in Argentina high-quality food production, environmental and wildlife conservation and social values. We do this through the organic management of our farmland and pampa grassland, running a profitable business while ensuring the welfare of our livestock and the health of our soil.


Our project is based on research and we promote our philosophy by providing technical advice and capacity-building, by offering practical demonstrations and experiments, and by disseminating knowledge and best practice.



The vision of “conserving through producing” is the legacy of Rachel and Pamela Schiele who, many years before their time, understood the importance of integrating wildlife conservation and animal and crop production. At Fundación Dos Hermanas the wild plants and animals are managed and protected by prohibiting the pesticides, weed killers and artificial fertilisers used in conventional farming, using the natural areas of the estancia, where we carry out planned wild flora and fauna conservation, for the benefit of our food production.

In our “land sharing” approach, as well as providing a home for rodents, armadillos, and pumas, the whole of the estancia conserves wildlife; earthworms and insects feed wild birds and animals and create natural soil fertility. Our pampas grasslands and species-rich corridors provide good grazing for cattle and  habitat for invertebrate predators, which migrate into the crops and help control insect pests. Our nature-based farming system minimises the use of finite inputs and also the impact on the climate; it protects the land, air and water and produces food free from chemical residues.

Sustainability, Responsibility and Innovation


The organic farming system:

  • respects the environment

  • minimises the use of finite resources

  • maintains and improves soil fertility

  • ensures high standards of animal welfare


Organic certification following internationally agreed standards guarantees to consumers that the food we produce is of high nutritional quality, and is grown without pesticides or genetically modified organisms (GMOs), and thus provides us with premium markets.

The organic system of farming provides the basis for integrating conservation and food production at Fundación Dos Hermanas.

We work with scientists and research, providing them with natural environments for studies in grasslands, soils, birds, small mammals and amphibians.


We offer training for producers, advisors and others interested in conservation practicers associated with sustainable organic production.


The estancia's community

Most of our employees and their families choose to live on the estancia, where we provide them with some of their food, including organic meat, vegetables and milk. Their houses are provided with electricity, water, and internet and we provide school transport for their children.

Everyone who works at the estancia is aware of the uniqueness of the Foundation’s approach, and they receive training in organic production and in conservation, in addition to more conventional job training.

Fudación 2 Hermanas


The estancia Dos Hermanas consists of 4,189 ha in Arias, Córdoba Province, Argentina, bordering an alkaline lake. The estancia includes farmed land and natural pampas grassland grazed by cattle producing beef and milk. Our organic-certified mixed-farming system aims to be economically, environmentally and socially sustainable; we put it forward as an alternative model to the intensive, high-input monocultures of conventional farming. 

The links between the health of soil, plant, animals and humans is at the centre of what we do.
