Senate approves and adopts 2017 2019 mtef presented by buhari

It appears you're referring to a news article or a statement from the Nigerian government. Here's a breakdown of what it might mean:

In simpler terms, the MTEF is a plan that outlines the government's expenditure priorities and budget allocations for a three-year period. It's a crucial document that helps guide the country's economic and financial decisions.

By approving and adopting the MTEF, the Senate is essentially giving its stamp of approval to the government's plan for the next three years. This means that the government can now proceed with implementing its budget and expenditure plans, which are aligned with the MTEF.

It's worth noting that the MTEF is typically presented to the National Assembly (which includes the Senate and the House of Representatives) by the President, and then approved and adopted by the Assembly. This process is an important part of the budget-making process in Nigeria.
