Project Portfolio Management (PPM) is a combination of projects or a set of business practices that integrates projects under the sponsorship organizations. These require different approaches, strategies, models, and practices when managing projects and programs within the portfolio. In Nigeria, many organizations have projects, subsidiaries, and branches in many cities across the country. However, they fold, abandoned, temporarily suspended or close within a decade or two, which is worrisome. These are linked to their PPM practices. As such, the aim of this paper is to identify, assess and discuss the PPM practices in Nigeria’s construction organizations with a view to examining the effects of such practices on the project portfolios. The research reviewed data from journals, conference/seminar/workshop papers, the internet etc. on the Project Portfolio Management (PPM) related fields and areas that help to identify, and narrow fourteen-PPM practices within the Nigerian and Global Context. These identified practices form the backbone of the research questionnaire, randomly administered to various professionals in Nigeria’s construction industry. In the overall analyses, these fourteen-PPM practices are significantly effective in terms of good performances in PPM organizations in Nigeria’s construction industry. These practices provide positive results on the overall PPM performances in achieving the organizational objectives in the portfolios.

Incidence of poverty, budget cuts and under development in Nigeria calls for a rethink on the economic planning and social policies if we really want to see sustainable economic development. This is informed by the increasing widening gap that has developed overtime between the rich and the poor, and between rural areas and urban areas. It seems that government’s provisions are either not enough or failing, this study will want to take a deep look into the system and provide an alternative way out to ensure and foster cooperation and sustainable economic development in Nigeria. To do these, the study evaluates the impact of rural road constructions; unemployment and school enrolment on Poverty Index and Gross Domestic Product. Secondary data was collected from reliable and authentic sources and these were analyzed by multivariate regression. The result obtained show that Expenditure on Rural Roads (ERC) (β = -4.177, t-statistic = -1.257; P>0.05), Unemployment Rate (UR) (β = -0.018, t-statistic = -0.035; P>0.05) and School Enrolment (SE) (β = 0.086; t-statistic = 0.721; P>0.05) were insignificant independent predictors of Poverty Index. - PI = 62.731-4.177ERC-0.018UR+0.086SE. Also Expenditure on Rural Roads (ERC) (β = -14.452, t-statistic = -0,265; P>0.05) and Unemployment Rate (UR) (β = -11.644, t-statistic = -1.427; P>0.05) were insignificant independent predictors of Gross Domestic Product while School Enrolment (SE) (β = 6.424; t-statistic = 3.275; P<0.05) is a significant independent predictors of Gross Domestic Product. - GDP = -1005.852-14.452ERC-11.644UR+6.424SE. These, show the need for Social investment when nearly all acclaimed variables have failed.
