In this study, we explore the long-term trends of floodplain population dynamics at different spatial scales in the contiguous United States (U.S.). We exploit different types of datasets from 1790–2010—i.e., decadal spatial distribution for the population density in the US, global floodplains dataset, large-scale data of flood occurrence and damage, and structural and nonstructural flood protection measures for the US. At the national level, we found that the population initially settled down within the floodplains and then spread across its territory over time. At the state level, we observed that flood damages and national protection measures might have contributed to a learning effect, which in turn, shaped the floodplain population dynamics over time. Finally, at the county level, other socio-economic factors such as local flood insurances, economic activities, and socio-political context may predominantly influence the dynamics. Our study shows that different influencing factors affect floodplain population dynamics at different spatial scales. These facts are crucial for a reliable development and implementation of flood risk management planning.

Milk supply response by dairy farmers in Delaware was analyzed employing distributed lag price structures for number of milk cows and milk production per cow. A polynominal distributed lag model is fitted to quarterly data with deflated prices for the period 1966 to 1978. The variations in the number of milk cows is explained by about 98 percent. Farmers react positively to milk prices after 1–2 years, while wages and feed prices have a negative impact on cow numbers. Milk production per cow shows positive adjustments to milk prices after 6 to 15 months. Technology and feed prices influence also milk production While the short-run price elasticity of milk production is only .2, the long-run aggregate elasticity grows to 2.8 percent. Intermediate-run projections of milk supply were also performed with the model.

Kyrgyzstan is very rich and striking with its ethnic composition. After the collapse of USSR, the changes in social infrastructure and the differentiation in the ideological premises of the state have led to a dramatic change in the population dynamics of the country. Now, the Kyrgyzstan Republic is a democratic and secular state. Ethnic structure, border security, long border with China are important issues of Kyrgyzstan, which, in its foreign policy, has drawn a profile that is open to the west, avoids conflicts with its neighbors, pursues a balanced policy in its relations with the US, Russia and China. Turkey is also an important partner of Kyrgyzstan; between Turkey and the Kyrgyz Republic, over 100 agreements and cooperation documents were signed in the fields of education, culture, trade and economic cooperation, transport, communication, military and other areas.
