Abstract

This paper investigated whether the Teakplantation established a year agoby Lagos State Government Ministry of Agric and Co-operative at Abia-Badagrymeet the soil and environmental requirement as obtainable in countries where Teakgrows naturally. Also the study will also establish whether the establishment ofTeak tree has changed the soil properties. Sampling design for this study wasbased on, the need to spread sample sites objectively over the study area. Theentire plantation is 2.5ha and five soil samples were collected from the plantationusing soil auger. From each of thefive (5) holes dug, soil samples were randomlycollected from two sampling depths 0 - 15 em and 15-30cm, respectively. Soilsamples were air-dried, sieved, 'and analyzed in the laboratory using standardtechniques. The result of the soil analysis show that PH, EC, TOM, TOC, TN, Av.K,Av.P and Bulk Density ranges between,5.36-5.86,38.00-156.00,1.06-2.41,0.86-1.92,0.01-0.03,0.03-0.03,0.02-0.02 and 1.31-1.36 respectively. Among theexamined variables,Ec has the highest mean (61.00) followed by pH (5.72) whileTN/Av.P remained the least value (0.02). Also, EC recorded the highest StandardDeviation (46.73).this was followed by TOM (0.52) while Av.K/Av. Based on theempirical data and the analysis carried out on the Teak plantation and the sitecharacteristics tofind out the suitability or otherwise of the site for maximum Teakyield in the country, it was found that the site characteristics, especially, soilproperties are similar to those'of places where Teak grows naturally. Therefore itis recommended to Lagos State Ministry of Agric and Cooperative to increase theplantation size.

Abstract

Science and technology on modern human create dualism result whichcomplete opposite. Those results are as proper instrument to fulfill increasinglycomplex of human needand as nature exploltatlon instrument with dehumanizationas result and also the trap of historical ratlona/lty. The hedonism ethics trend has asignificant role on the second result. It means, whether the hedonism terminologyis /lmlted with "lust" meaning which .refer to ego existence. Therefore the naturewill define as "phallus" which will explolt freely as the exploitation subject tofulfill the lust, and the heavy pollution on environment is unavoidable. Thishistorical ratlona/lty should be cut as an effort to save thefuture. Local wisdom isa promising therapy alternative. Local wisdom has universal values to return to thenature path,' namely ethical values with natura magistrate prlnclpal on interaction,interrelation and interdependency relation between human and nature. Only thlsharmony will able to maintenance the sustainable environmental protection to thefuture.

Abstract

Remote sensing technology has been adopted by various fields of sciencesince the Second World War. Its research varies greatly accordingly. Basically itcan be broken down into there types,i.e, (1)research using remote sensing just fordata acquisition, (2) research in theoretical remote sensing, and (3) research inapplied remote sensing. This article is about its differentiation.

Abstract

ABSTRACTEconomic development in decentralization era, presumably, will not besustainable if only supported by non-renewable resources. Then, local governmentneed to changefrom mining to non-mining based economic development. The nonrenewableresources themselves are used as capital in the transformation process.In supporting these endeavours, study of superior commodities in Bangka BelitungArchipelago Provinces is need to be conducted as efforts to increase society'swelfare or other stakeholders post decreasing of tinproduction this province.

Abstract

We studied the changes in stream water temperature (Tw) and waterquality (Wq) during rainfall events in forested watersheds. The parameters ofWq(88, DOC, N03--N, DTN, Na+, 8i and r) were observedinfour regionsof Japanfrom June 2004 to December 2005. The R values between Tw and those Wqparameters and between specific discharge (Qs) and Wq were positive, exceptforthe negativeones (Na+ and Si). Similarto the relationbetweenQs vs. Tw, hystereticloops in the relations between Qs vs. those Wqparameters were clockwise,exceptfor Na+ and Si as counter-clockwiseloops. This indicatesthat the'surfaceand subsurface flows contain higher concentrations of SS, DOC, IC, N03--N andDTN. To the contrary,the deeperpathwayscontainhigherconcentrationsof Na+and Si. These results suggest that the changes in Tw and Wq could be used tointerpret theflow paths.

Abstract

Thepurpose thispaper is to provide a broad overview of the recent patternsand trends of urban growth, and to discuss the relationship between urbanization,economic and population growth and environment in Semarang City. Over the last20 years many urban areas have experienced dramatic growth, as a result of rapidpopulation growth and as the world's economy have been transformed by acombination of rapid technological and political change. Centralistic type ofdevelopment from New Era Government gives consequences in the formation ofmega urbanization. As a geographic phenomenon, urbanization is seen as acontinuumfrom community level until global level. In the cases of Semarang, thereis much more than a doubling. Net migration in many cases contributes as muchas two thirds of the population growth in these zones, whereas in the city cores, netmigration contributes little to growth. The main factor which is influencingurbanization process in Semarang is the growth of service sector, especiallyinformal activities. A comprehensive model suggests that urbanization in Semarangis influenced by structural and social demographic factors. So, the balancebetween managing urban discharges to environment and enhancing environmentalresource capacity is key determinant of the sustainability of the development inSemarang and livabilitY in general
