In 2007 commercially viable quantities of oil and gas were discovered in Ghana. The estimated revenue of the oil reserves is about $1 billion per year (approximately EUR 768 million), which is similar to the amount of development assistance received by Ghana annually. As is often said, natural resources can be both a curse and a blessing. When managed well, they can boost development and foster economic growth. Oversight bodies such as parliaments, media and civil society organisations (CSOs) have a pivotal role to play in ensuring proper management of natural resources.
