A better developed transport infrastructure is also essential to improving the productivity of the agricultural sector. Its high production costs are in fact partly due to poor transport capacity. In that respect, irrigation systems, farm-to-market roads, and bridges are all examples of infrastructure developments that call for investment. They would improve the income and living conditions of rural households by reducing travel time and haulage costs as well as making basic social services such as schools and hospitals more easily accessible (Mangahas, 2010).
