Ghana: Addressing a forum on Land Administrative Project (LAP 2) in Accra, the Minister for Lands and Natural Resource, Alhaji Inusah Fuseini, noted that current development trends indicated that the world population would reach 9 billion by 2050 and that the demand for food was expected to increase to 70% while arable land would only be increased by 15%.

This, he said, called for a more effective and efficient method of food production and land management, an important and key element of which would be the availability of relevant and adequate geospatial information to the small holder, commercial food producers, fishermen and pastoralists. He said it was extremely critical for the country to attain at least three of the Millennium Development Goals (MDGs) set by the United Nations which included the good governance of land.

He said this while explaining the rationale behind government's formulation of the Land Policy in 1999 out of which the Land Administrative Project (LAP) was launched in 2013. He disclosed that the country was adopting a new projection system called Ghana Transverse Mercator (GTM) and the ellipsoid coinciding with International Terrestrial Reference Frame (ITRRF) with a new Datum to be called the Ghana Geodetic Datum. He added that a National Geodetic Reference network would provide support for land surveying, mapping, engineering surveying and related application.

The Government of Ghana, through the Ministry of Lands and Natural Resources, is implementing the second phase of the Land Administrative Project (Lap 2), a consultative service that would provide a strategy for the development of modern geodetic reference network. The project is being funded by the International Development Association (IDA), Canadian International Development Agency and the Government of Ghana.
