Instrumental neutron activation analysis (INAA) technique was used to investigate the abundance and distribution of rare earth elements (REE) in soil around Kaduna Refinery. The aim of the study is to assess the rare elements potential of Nigeria for economic exploitation. Five REEs (La, Dy, Eu, Yb, and Lu) were detected in varying concentrations ranging from a minimum of 0.6 µg/g (Lu) to a maximum of 249.0 µg/g (La). The elements existed with trends consistent with the natural pattern of REEs in soil, showing significant Eu and Dy anomalies which characterize upper plains and flood plains. The levels of REEs in soil in the study area were generally slightly above background levels, with minimal (La, Dy, and Eu), moderate (Yb), and significant (Lu) enrichments and trending: Lu ˃Yb ˃ Eu ˃ Dy ˃ La. The abundance of the REEs investigated cannot establish a potential of Nigeria for economic exploitation of the mineral, hence, rare earth project in the study area is not viable at the moment.

The fragment of the legend of the map concerning the vegetation of flood- plains and river-valleys in the subzones of northern and southern deserts is presented in the article. The map is compiled in Department of Vegetspon Geography and Cartography of Komarov Botanical Institute by a large team of botanists-geographers of the former USSR. The nature environments determining the development of vegetation of river-valleys in arid climate are conditioned by the intrazonal factors (alluvial and flood processes) at the background of natural zonal factors. Contrasts of environments and corresponding plant communities manifest themselves first of all. Mineralization of ground waters, salinity of soils, including the alluvial ones, are of essential importance. The practice of vegetation mapping of unstable habitats, to which floodplain landscapes belong, has shown that units of phytocoenological classification is of little use for this purpose. The heterogeneity of vegetation, consisting of short-term unstable serial communities generates a need for typification of space combinations of such phytocoenoses. For this purpose it is convenient to use generalized ecological-dinamic series, including plant communities of all levels within the limits of definite segment of valley. These series are the mapping units on the map. The vegetation of the first terrace is also nessecary to include in a single series with flood-plain vegetation because it has supplementary influence of ground waters. The higher divisions of the legend are based on zonal characters: vegetation of valleys in northern, middle and southern deserts. 13 numbers are used to show the vegetation cover of flood-plains and valleys. Additional 7 numbers are used for the out-of-valley meadow vegetation. The content is enriched by using of the letters by the numbers showing the geographic variants of series and ciphers for combination of series and out-of-series communities. The text legend is supplemented by the matrix (table), showing the subordination of subtitles, zonal position and geographic distribution of divisions. The types of series in the matrix are listed with indication of the main dominant species that gives the additional information on the legend divisions. The author's conclusion is that valley vegetation reveals clearly the zonal features, correlating with zonal (desert) vegetation.

Florence made landfall on the southeastern coast of North Carolina (NC) generating torrential rainfall and severe flooding that led to 53 fatalities in three states (NC, SC, and VA) and $16–$40 billion in damage. Seventy-seven percent (77%) of the fatalities occurred in the rural flood plains of NC with Duplin county reporting a high of eight deaths. Approximately 50% of the total number of hurricane-related fatalities across the three states were vehicle-related. The predominant demographic at risk were males over the age of 50 years. The type of property damage was in line with other major hurricanes and predominantly affected residential structures (93% of the total number of damaged buildings). Florence is among the top 10 costliest hurricanes in U.S. history with approximately 50% of the damage projected as uninsured losses due to residential flooding. The cumulative 5-day rainfall resulted in major flooding along the Cape Fear, Lumberton, and Neuse rivers where many industrial waste sites (hog manure lagoons and coal ash pits) are located. Several of these waste sites located in the flood plain were breached and have likely cross-contaminated the waterways and water treatment operations. The observed extent of the flooding, environmental contamination, and impact to public health caused by Florence will add to the long-term disaster related mortality and morbidity rates and suggests an expansion of the 100-yr flood hazard zone to communicate the expanded risk to the public.

Abstract The New Madrid Seismic Zone (NMSZ) has historically recorded some of the largest intensity earthquakes in North America, including significant earth movements that resulted in about 2,000 felt earthquakes during 1811-1812. The region continues to experience mass wasting due to earth movements. The aim of this study is to understand the influence of geologic variables on mass wasting processes in the greater Cape Girardeau area; which forms the commercial center of Missouri's fertile "Bootheel" region. Earth movement susceptibility was evaluated in Cape Girardeau and Bollinger counties and portions of Stoddard and Scott counties by mapping potential landslide features on topographic maps, field verification of such features, and geospatial analysis of recent LiDAR imagery. In order to evaluate the changes in surface morphology, slope inclination, hillshade aspect, hydrology, lithology, faults, precipitation, seismicity, sinkholes, and geohydrology were considered. Geographically weighted analysis of the geomorphologic variables identified zones of relative risk. In addition, data were evaluated for oil and gas pipelines, bridges, utilities, and open pit mines associated with mass wasting on public and economic infrastructure. The results suggest that anthropogenic changes commonly associated with urban development impact land use, runoff, infiltration, and slope failures, while sustained precipitation and seismic ground shaking tend to trigger landslides. The scale of mass wasting in the study area was robust, varying from as small as one-half hectare to as much as 67 km2. The vulnerability of the population in susceptible areas tends to increase at the lower elevations and on alluvial flood plains. Thus, hazard susceptibility evaluation can be useful in both community planning as well as emergency preparedness.

Potential Area

Perairan umum daratan Indonesia mempunyai luas 13,85 juta ha yang terdiri atas 12,0 juta ha sungai dan paparan banjiran (flood plains), 1,8 juta ha danau alam (natural lakes) dan 0,05 juta ha danau buatan (man made lakes) atau waduk (reservoirs). Potensi perikanan tangkap di perairan umum daratan ditaksir mencapai 3.034.934 ton per tahun. Perairan umum daratan berperan penting sebagai sumber protein dan ketahanan pangan, sumber ekonomi masyarakat, sumber lapangan kerja, sumber plasma nutfah dan genetik, sumber devisa dan pendapatan asli daerah, serta obyek wisata alam (ecoturism). Perairan umum daratan yang terabaikan akan berdampak terhadap penurunan potensi luasnya, keanekaragaman jenis ikan, produksi ikan, kesempatan dan peluang kerja (peningkatan pengangguran), pendapatan asli daerah, dan fungsi estetika. Pengelolaan perairan umum dengan benar akan berpengaruh terhadap peningkatan produksi minimal 20% dan fungsi ekologis, sehingga perikanan perairan umum daratan dapat dijadikan tumpuan pembangunan perekonomian masyarakat, khususnya nelayan. Berbagai upaya yang dilakukan untuk membangun perikanan perairan umum daratan antara lain mempromosikan akan penting dan peranan sub sektor perikanan, memberikan perhatian terhadap riset di bidang sumber daya perikanan, melakukan valuasi sumber daya, melaksanakan monitoring dan evaluasi (termasuk perbaikan statistik perikanan), mengembangkan ko manajemen dan kapasitas sumber daya manusia.Inland waters of Indonesia has a total area of 13.85 million ha composing of 12.0 million ha rivers and flood plains, 1.8 million ha natural lakes and 0.05 million ha man made lakes/ reservoirs. Total of fish potential yields of the inland waters was estimated to be 3,034,934 ton per yr. The inland waters plays an important role as source of protein and food security, source of economic and supporting livelihood of the peoples, source of employment, sources of genetics and germ plasm, contributing to foreign exchange and local government earning, and eco-tourism. The neglecting inland waters has affected on the decreasing potential area, fish potential yields, fish species diversity, employment opportunity, and local government earning and the ecological function. Management of the resources could impact on the increasing fish yields at least 20% and its ecological function, so that the inland waters fisheries can be used as a based of economic development of the peoples especially for the fishers. Some efforts which should be done in development of the inland waters fisheries are promotion of the role and importance of fisheries between other sectors, prioritizing research on fisheries resources, valuation of inland waters fisheries, monitoring and evaluation (including fisheries statistics), development of fisheries co-management and capacity building of the human resources.
