Appraisal Of Social And Health Impact Of A Cement Plant At Host Communities In Yandev, Nigeria, Fanan Ujoh Ph.D, Frederick Terkuma Ujoh Mr

Dr. Fanan Ujoh

Nigeria has extensive mineral and natural resources hence, developmental projects are being proposed and executed on a daily basis, many of which involve large-scale alteration of human, animal and plant ecosystems. Limestone mining and cement production commenced in 1980 at the study area, Yandev, without an environmental impact assessment to ascertain the extent of impact these activities could bring to bear on the physical and living conditions of the host environment. This study was carried out to appraise the social and health impact that mining of limestone and production of cement has inflicted on the host communities. Descriptive statistics and …

Post-Fire Succession In Californian Coastal Sage Scrub: The Role Of Continual Basal Sprouting., George P. Malanson, W. E. Westman

George P Malanson

Dominant shrub species of coastal sage scrub in coastal southern Cali- fornia are able to produce shoots from their base on a continual basis in the absence of fire or other major defoliation. As a result, each shrub becomes a population of mixed-aged branches (ramets) and extends its duration in the canopy beyond the age of any of its above-ground phytomass, reduces the incidence of senescence, and per- mits an individual (genet) to survive during long fire-free intervals. A computer sim- ulation of succession in coastal sage scrub under differing fire intervals shows that continual basal sprouting may be significant …

Improving Environmental Simulation Models To Assess Climate Change Impacts, George P. Malanson, Marc P. Armstrong

George P Malanson

Increased levels of atmospheric carbon dioxide and other by-products of human civilization are expected to disrupt the global energy budget and induce climatic change, which will aIter the distribution of plant species and the composition of plant communities. In spite of the importance of these projected effects, our understanding of the processes leading to such changes needs to be strengthened. This paper addresses the need to improve models that are used to assess spatial aspects of the response of vegetation to anthropogenic climate change. Several modifications are suggested, each of which relates to changes in forest community composition that occur …

Farm Chemicals As Indicators Of Sediment Sources In Iowa Rivers, George P. Malanson, E. N. Nealson

George P Malanson

Determination of the source of sediment in rivers and streams is important in order to effectively implement a program to reduce its concentration. This project uses agricultural chemicals as indicators of current sources of sediment from farm fields in the Cedar River, Iowa watershed. We hypothesized that the relations of sediment, nitrogen, and phosphorous yields to precipitation would indicate whether sediment originated from erosion of fields or from channel bank erosion of floodplains. The changes in sediment, nitrate, and phosphorus in the channel in response to rainfall events were determined. In simple regressions, all three variables have similar slopes when …

Ordination Of Woody Vegetation In A Ouachita National Forest Watershed, George Malanson, Denise Marion

George P Malanson

Species response to competition and other environmental gradients has important implications for forest ecosystem managers who desire to both maintain diversity and provide a sustained flow of forest goods and services. Woody species on a 140-acre watershed in the Ouachita National Forest are ordinated with detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA) to identify the important influences on species distribution at this scale. Species composition is found to respond primarily to a moisture gradient, and secondarily to competition with shortleaf pine (Pinus echinata Mill.). Centrifugal organization of species along gradients is suggested by the relative locations of species …

Reinterpretation Of Relations Between Vegetation Removal And Water Yield, George P. Malanson, D. P. Post

George P Malanson

While the relation between vegetation clearance and increasing streamflow appears to be strong for data aggregated among geographic regions, results are equivocal in local areas. Earlier data are re-analyzed to consider the role of hydroclimatology. While vegetation clearance increases absolute streamflow, the proportional change is not significant. Residuals of regressions of absolute and proportional change in streamflow on vegetation clearance are related to precipitation, with positive and negative slopes, respectively. A few outliers with high responses are important in creating a pattern, and hydroclimatology is a better predictor of change in streamflow than is vegetation clearance for aggregate data. With …

Are Green Cities Nice Places To Live? Examining The Link Between Urban Sustainability And Quality Of Life, David S. Bieri

David S Bieri

The growing importance of nonmarket assets such as the environment, combined with the unprecedented availability of high-resolution data, has renewed broad interest in quantifying sustainability at different spatial levels. Policy-related decision making requires that potential sustainability measures meet three key requirements; (i) sustainability metrics need to be comprehensive such that they reflect the experience of representative households; (ii) sustainability indices need to be comparable across different geographic scales, and; (iii) measures of sustainability need to be economically meaningful, ideally tying into the larger system of national accounts. However, conventional sustainability indices do not tend to meet these criteria, rendering them …

Socio-Environmental Considerations At The Usuma Reservoir In Abuja, Nigeria, Fanan Ujoh Mr, James Ikyernum Mr, Olarewaju O. Ifatimehin Dr

Dr. Fanan Ujoh

Reservoirs are Man’s attempt towards water re-distribution from regions/seasons of abundance/surplus to regions/seasons of scarcity. This study focuses on socio-environmental impacts of the Lower Usuma dam in Abuja, on its four surrounding communities. Stratified random sampling technique was employed in the administration of a questionnaire to 200 respondents. Using descriptive statistics and the student t-test for the analysis, the study discovered that: (i) there has been no significant improvement in infrastructure provision by Government; (ii) cases of water-borne diseases are high; (iii) the communities have lost land for cultivation; and, (iv) the communities believe that the resettlement scheme is not …

Resource Conflict Among Farmers And Fulani Herdsmen: Implications For Resource Sustainability, Olarewaju Oluseyi Ifatimehin, Marietu Tenuche

Olarewaju Oluseyi Ifatimehin

This study describes the traditional relationship between farmers and Fulani herdsmen in the incessant resource conflict witnessed in Kogi State, Nigeria and how it affects livelihood security of those involved and resource sustainability for the communities. These conflicts are most responsible for the unsustainable utilization of land and water resources as the trampling by the hooves of herds of cattle compacts the soil of farm land, destroy farm crops by the herdsmen, places restraint on effective utilization of arable farmland among other destruction of available resources. It is understood that these conflicts have their roots in the land tenure system, …

Globalization & Nationalism: A Recipe For Terror, Cari Bourette, Daniel Reader

Cari Bourette

Nationalism appears to be part of the human condition; it may well be related to the human tendency toward tribalism. Whatever the case, nationalism appears to be a permanent feature on the global landscape. Globalization, while not a new phenomenon by any means, seems to be having a tremendous dilutory effect on the sovereignty of states; it now appears to be carrying the assault to the cultural frontiers of nationalism. Unlike the Westphalian constructs, however, nations will not so easily succumb. There is a greater inherent resistance to change in nations; the only historically effective method has been outright eradication …
