The image was taken in 2001. A side-by-side comparison of what the place looked like in 1986 and 2001 can be found by clicking here. 
What does this photo show? Nothing but the effects of increased migration from the Altiplano to the Santa Cruz lowlands, and the application of Aymara production and land distribution techniques. The pie or radial patterned fields are part of the San Javier resettlement scheme. They are the visual translation of Andean communitarism imported to the Eastern part of the country.
You shouldn't be surprised by the fractioning of the land, this is a common feature of "ancestral" altiplanic methods of production. In post-colonial altiplano, land is/was inherited in such a fractional manner, and of course, with time, efficiency began to suffer. Eventually the mini-fundio became commonplace and nowadays, some communities subsist even under a "surco-fundio" system. The pattern is being replicated in the Bolivian lowlands, despite the availability and knowledge of alternative production methods, we can only expect the same ultimate result for any redistributed lands. The fields illustrated in the photograph are not producing soybean or any other "cash crops" such as rice or wheat, they are too small for efficient production. 
What's next? As you read this, the Morales government is preparing the second (or third) Land Reform in Bolivian history, 4.5 million hectares (about 17,375 square miles - the size of the states of the state of Massachusetts and New Jersey combined) are to be redistributed to the indigenous poor, the same folks who are now eking an existence in the communities such as the one seen above, or are just about ready to abandon their minifundios in the altiplano.
Other than property rights being obliterated, what worries me are the upcoming decreases in national food production once the fields targeted for reform are

 Surco is refers to each of a field's furrows. Under a "surco-fundio" each row has an owner.
