Riau is a province of Indonesia, located in the centre and eastern coast of Sumatra along the Strait of Malacca. Until 2004 the province included the offshore Riau Islands, a large group of small islands (of which the principal islands are Batam and Bintan) located east of Sumatra Island and south of Singapore, before these islands were split off as Riau Islands Province in July 2004. The provincial capital of Riau Province and its largest city is Pekanbaru. Other major cities include Dumai, Selat Panjang, Bagansiapiapi, Bengkalis, Bangkinang, Rengat and Siak Sri Indrapura.
Riau is currently one of the richest provinces in Indonesia and is rich with natural resources, particularly petroleum, natural gas, rubber, palm oil and fiber plantations. However extensive logging has led to a massive decline in forest cover from 78% in 1982 to only 33% in 2005. This has been further reduced an average of 160,000 hectares per year on average, leaving 22%, or 2.45 million hectares left as of 2009. Deforestation for palm oil and paper has led to not only perennial serious haze over the province, but in Kuala Lumpur, Malaysia, and intensifying flooding and landslides. Kuala Lumpur and surrounds has been sent into "unhealthy" air quality levels again in mid-2012 from Indonesian haze originating in Riau.
Since the 1970s, much of Indonesia has experienced declining population growth rates. Riau has been a significant exception, with increasing rates every decade since 1970 to a 4.35 percent annual rise for the 1990s. The provincial population is 5,543,031 (as at the 2010 census).
Riau Province is home to various dialects of the Malay and Chinese language. The dominant language used by the Malay population is Malay. The Chinese population (predominantly Hokkien) speak a variety of Chinese dialects, the most common being Min Nan, originating from the southern part of Fujian province in the south-eastern part of China.
Riau Malay 
The dialect of Malay spoken in Riau Province is considered by linguists to have one of the least complex grammars among the languages of the world, apart from creoles, possessing neither noun declensions, temporal distinctions, subject/object distinctions, nor singular/plural distinction. For example, the phrase Ayam makan (lit. 'chicken eat') can mean, in context, anything from 'the chicken is eating', to 'I ate some chicken', 'the chicken that is eating' and 'when we were eating chicken'. Riau also have a traditional script named Arab Melayu. It's look like arabic script but the words are written in indonesia A possible reason for this is that Riau Indonesian has been used as a lingua franca for communication between different people in this area during its history, and extensive foreign-language speaker use of this kind tends to simplify the grammar of a language used.
It is sometimes supposed that Riau Malay is the basis for the modern national language, Indonesian. However, that is instead based on Classical Malay, the court language of Riau, which is distinct from the local dialect.

The economy of Riau expands faster (8.66% in 2006) than the Indonesian average (6.04% in 2006), and is largely a resource-based economy, including crude oil (600,000 bpd), palm oil, rubber trees and other forest products. Local government income benefits from a greater share of tax revenue (mainly from crude oil) due to the decentralization law of 2004.
Riau's forest area is around 2 million ha. reduced from 8 million ha. Giam Siak Kecil – Bukit Batu Biosphere Reserve, Indonesia, is a peatland area in Sumatra featuring sustainable timber production and two wildlife reserves, which are home to the Sumatra tiger, elephant, tapir, and sun bear. Research activities in the biosphere include the monitoring of flagship species and in-depth study on peatland ecology. Initial studies indicate a real potential for sustainable economic development using native flora and fauna for the economic benefit of local inhabitants.
Cagar Biosfer Giam Siak Kecil Bukit Batu (CB-GSK-BB) is one of seven Biosphere Reserves in Indonesia. Located in two areas of Riau Province, namely Bengkalis and Siak. CB-GSK-BB is a trial presented by Riau at the 21st Session of the International Coordinating Council of Man and the Biosphere (UNESCO) in Jeju, South Korea, on May 26, 2009. CB-GSK-BB is one of 22 proposed locations in 17 countries accepted as reserves for the year. A Biosphere Reserve is the only internationally recognized concept of environmental conservation and cultivation. Thus the supervision and development of CB-GSK-BB is a worldwide concern at a regional level.
CB-GSK-BB is a type of Peat Swamp Forest is second to none, unique to the Kampar Peninsula Peat Forest (with a small area of swamp). Another peculiarity is that the CB-GSK-BB was initiated by private parties in cooperation with the government through BBKSDA (The Center for the Conservation of Natural Resources), including the notorious conglomerate involved in forest destruction, Sinar Mas Group, owning the largest paper and pulp company in Indonesia.
