Rwanda is less than half the size of Scotland, but is home to more than eight million people. The country is tucked deep in the heart of Africa, more than 1500 km from the nearest sea port. Within its borders are packed mountains, rivers, lakes, marshes, savannah and forests – including Nyungwe, the largest single remaining tract of montane forest in East and Central Africa. Tea and coffee bushes vie for space on the intensively cultivated hillsides with a patchwork of farms covering the slopes and valleys.
