The objective is to bring to fore the neglect of grain legumes production in such strategies and for improved understanding of the need to implement grain legumes specific programs for enhanced food security in the country. The paper reiterates that grain legumes were neglected in most of the strategies for increased crop production which presented enormous challenges and reflects largely the inbalance in the policies for the attainment of food self-sufficiency and food security in the country The paper gives an overview of the programs and projects, and reviews the output of grain legumes during the period （1970-2007）. It submits that the activities of some research institutes and the presidential initiative on vegetable oil development program had positive impact on the output of legumes which is an added impetus for the need to establish grain legumes specific research institutes and programs for further productivity increases. Constraints identified by the paper include： poverty, storage systems, among others. It itemizes prospects and current challenges for grain legume crop sub-sector in Nigeria.展开更多

This research paper analyzed the 2005 IO （input/output） table to create building industry-related intensities and, at the same time, compared the building industry with industries at large for distribution margins and transportation. The analysis of distribution margins separately for middle and purchaser margins found that middle margins in the building industry are minor at 35% of the averages for all industries, while purchaser margins are sizable at 1.8 times, proving that it is an industry for which local production for local consumption is quite effective. CO2 emissions resulting from transportation in the building industry were calculated and concisely characterized. Although the ratio of transportation CO2 emissions to total CO2 emissions in each industry finds almost no difference between general industries and the building industry, transportation CO2 emissions per production value are two to three times heavier than those from general industries to be justified as a transportation-intensive industry.展开更多
