Rondônia is nestled in northwest Brazil, with Porto Velho as its capital city. It boasts a total area of 237 576.16 square kilometres, which is equivalent to 91 729 square miles. Rondônia is bordered by Acre, Amazonas, Mato Grosso and Bolivia. A major part of this state’s appeal lies in its being home to a vast proportion of the Amazon Forest.

Because this area has always been covered in dense jungle foliage, the first European explorers in Brazil were hesitant to brave this land. So, in addition to the native tribes that had been occupying this region for centuries, the only other inhabitants were Jesuits and bandits that had imposed themselves in search of wealth.

The area remained relatively untouched until the 1800’s, when the rubber industry became significant throughout Brazil. But even during this time, Rondônia remained one of the quieter states in terms of the rubber rush.

During the 20th century, there were significant feuds regarding the territories of Acre, another Brazilian state. The Treaty of Petropolis was drawn up to define the borders between Bolivia and Brazil, and required that Brazil construct a railway that would stretch some 366 kilometres. This railway was called Madeira-Mamoré. The village that was built as a home for the workers building the railway would grow and develop, eventually becoming the modern capital of the state, Porto Velho. Initially, Rondônia was recognised only as a Territory. However, in 1981, it achieved the status of being a State.

Although having been occupied by luscious forests for centuries, Rondônia is now suffering the consequences of massive deforestation as a result of overpopulation and excessive agriculture. In fact, Rondônia is recognised as being one of the most vulnerable areas in terms of the depletion of the rain forests. Urban areas are the main epicentres for the residents of the state.

The climate of Rondônia is hot and humid all year round. These are the ideal conditions to foster the dense jungles of the state, which (while depleted) are still home to a fascinating array of plants and animals.

Different sectors support the GDP, or Gross Domestic Product. The largest contribution is made by the service segment of the economy, followed by industry and agriculture. Rondônia’s main export is timber, but coffee and granite are also important exports.
