The case study reported below examines USAID's "Linking Agricultural Markets with Producers" program. This program complemented Bosnia and Herzegovina's overall sustainable agriculture policies. Implementing organizations quickly recognized that sustainability must be achieved not only from an environmental perspective, but in the interorganizational domain as well. Public, private and nonprofit players had to develop the social, economic and political infrastructure required for sustainable agricultural projects to succeed. These institutional changes were at times more difficult than the sustainable agriculture policies and practices they supported. Framed within LAMP's identification of constraints and proposed solutions for agricultural reform, we explored the interorganizational linkages required for success. We identified three distinct types: 1) those within the international community, 2) those within the local community and 3) those between international and local organizations. The case illustrates the institutional and managerial obstacles to and opportunities for implementing sustainable development reforms in transition settings.

In the middle of the twentieth century, banks changed from ‘closed’ designs signifying wealth, security, and safety to ‘open’ designs signifying hospitality, honesty, and transparency as the perception of money changed from a passive physical substance to be slowly accumulated to an active notational substance to be kept in motion. If money is saved, customers must trust that the bank is secure and their money will be there when they want it; if money is invested, customers must trust that it is being done openly and honestly and they are being well-advised. Architecture visually communicates that the institution can be trusted in the requisite way.

Investing in transport infrastructures such as roadways, airports and seaports has proven to improve a country's trade performance through reduction of transportation costs and providing access to production and market. This research investigates the diminishing return of infrastructure investment and also the rate of return of two types of infrastructure investment strategies on trade. An augmented gravity model is used with econometric analysis methods in this study. The results have shown that as roadway and airport densities increase, the marginal returns on trade decrease. Empirical evidence from the United States and China with all their trading partners from the past twenty years has also suggested existence of diminishing return of infrastructure investment on roadways and airports. Infrastructure investment strategy that focuses on increasing roadway and airport density experiences smaller diminishing return on trade. In contrast, seaport investment that focuses on port quality and efficiency generates higher return on trade. A trade benefiting infrastructure investment strategy that best utilizes financial resources must balance between quality and quantity based on a country's current level of infrastructure asset.

Transportation has contributed to climate change and will most likely be impacted by changes in sea level, temperature, precipitation, and wind, for example. As the risk of climate change impacts become more imminent, pressure for adaptation within transportation agencies to address these impacts continues to rise. The most logical strategy is to integrate consideration of adaptation projects into the long-range transportation planning (LRTP) process. To do this, tools and experience are needed to assist transportation agencies. The Climate Change Adaptation Tool for Transportation (CCATT) is a step-by-step method to evaluate climate change scenarios and impacts, inventory at-risk existing and proposed infrastructure, and assess mitigation practices to identify supporting adaptation efforts. This paper focuses on the application of CCATT to the Mid-Atlantic region using a case study on the Wilmington Area Planning Council (WILMAPCO), the Metropolitan Planning Organization for northern Delaware. The results of the application and case study demonstrate the importance of climate change adaptation practices in long-range transportation planning. DOI: 10.1061/(ASCE)TE.1943-5436.0000515.
