The yearly dose of havoc unleashed from the overwhelming forces of changing climatic parameters on coastal communities does not differentiate among boundaries when inflicting damages of any kind. For that, in the last several years, climate risks continue to plague the southern portion of Texas. Give its location, the South Texas’ region, and adjourning areas along the Gulf of Mexico as a hub for speculative capital and natural resource extraction face exposures from the menace of tropical storms of immense scales. The ferocious pressures from heavy storms in these settings are such that, they often leave in their wake indelible footprint on the surrounding ecology. This comes with extreme impacts on both the natural and built-up environments particularly around big cities holding vital infrastructure crucial in economic development and productive capacity of petroleum and natural resource assets of South Texas. While the situation is further compounded by the region’s propensity to natural disasters and the fragile coastal ecosystem close to enormous network of large-scale energy infrastructure made up of oil and gas fields, refineries, and pipelines. The presence of petrochemical complexes, thriving natural resource base, transportation corridors, burgeoning urban centers, and neighborhoods often at the receiving end of recurrent climate hazards over time, increases the inherent risks, due to environmental, physical, and socio-economic and policy factors located within the larger regional ecosystem. Yet, current studies in climate change have done very little in assessing the situation in south Texas region with the latest advances in geospatial information technology under a mix scale orientation. Considering these voids in research, this paper assesses changing climate impacts in the South Texas region using secondary data analyzed with descriptive statistics and (GIS) Geographic Information System under a mix scale method. With emphasis on the issues, trends, impacts, factors, and mitigation measures. The results revealed widespread occurrence of climatic hazards in the study area with visible impacts in the form of heavy floods from storms leading to environmental damages. This involves also risks to petroleum amenities and displacement of citizens and the loss of properties. The GIS mapping of the trends pinpointed clusters of heavy presence of stressors and degraded amenities dispersed across space over time with linkages to socio-economic, physical, and ecological elements. To remedy the situation, the paper proffered numerous solutions ranging from the adoption of effective policy, growth management, monitoring, the design of a regional climate information systems and education of the public.

Chilli ( Capsicum annum L.) is an important spice crop grown in Sri Lanka. Deficiency of micronutrients, especially Mn, Zn and Cu reported in chilli growing areas has affected adversely on chilli production. Therefore, a study was conducted to evaluate the effect of foliar application of Mn, Zn and Cu on growth and yield of chilli grown in Reddish Brown Earth soils (Rhodustalfs), in dry zone, Sri Lanka. Seven treatments were tested in a greenhouse as pot experiment. Nitrogen, phosphorus and potassium were added into all seven treatments. Manganese Zn and Cu were added separately as foliar application for three treatments. One treatment had all three elements and control treatment had only N, P and K but no any added elements. Since all micronutrients were added as their sulfate form, last two treatments had S with N, P and K to assess the effect of S on plant growth. Copper with N, P, K added treatment showed significantly higher growth and yield compared to other treatments. It showed about 25% yield increment compared to control treatment. Therefore, it can be concluded that application of Cu is beneficial to obtain a better yield in chilli in Reddish Brown Earth Soils (Rhodustalfs). However, further field studies are needed to confirm findings.
辣椒(Capsicum annum L.)是斯里兰卡重要的香料作物。据报道，辣椒产区微量营养元素特别是锰、锌和铜的缺乏对辣椒生产产生了不利影响。为此，研究了在斯里兰卡干旱地区红棕壤(Rhodustalfs)土壤上施用锰、锌和铜对辣椒生长和产量的影响。在温室盆栽试验中对7个处理进行了试验。7个处理均添加氮、磷、钾。3个处理分别叶面施用锰、锌和铜。其中一个处理全部添加了3种元素，而对照处理只添加了N、P、K，不添加任何元素。由于所有微量元素均以硫酸盐形式添加，最后两种处理均以氮、磷、钾为主，以评价S对植物生长的影响。氮、磷、钾加铜处理的生长和产量显著高于其他处理。与对照处理相比，产量增加约25%。综上所述，铜的施用有利于红棕壤辣椒产量的提高。然而，需要进一步的实地研究来证实这些发现。

In a world where we discuss sustainability as the central axis of development, it is essential that a country like Brazil takes responsibility to adopt new technologies that contribute to the this sector. Taking advantage of the need that the country has to ally economic growth with social inclusion and maintenance of natural resources, the adoption of technologies that reduce the emission of greenhouse gases is promising. In this sense, stimulate the hevea culture appears to be an important allied in the fight to the concentration of CO2 in the atmosphere, since it allows its uptake by the trees. The retaken of this vegetal exploitation in Brazil (specially by the State of Rio de Janeiro), taking the social inclusion as a guiding policy, can be crucial to the fight against poverty and unemployment. This exploitation will allow to create conditions for small farmers to participate in the production chain of natural rubber, raw material extracted from rubber trees.

Scavengers play a major role in the waste management process in developing countries. This study analyzed the informal recycling activities carried out by scavenger in the Tafila region of Jordan. The results show that scavengers have an important role in the informal solid waste management (SWM) especially in term of waste reduction, minimization and material recovery. Significant values from the scavenged material make the scavenging somewhat a profitable business for poor people and could track more in the future. Socially scavenging tends to be acceptable in the community, especially with the increasing of the poverty and employments rates and became more acceptable in rural areas as it is already in urban areas. Despite the low level of education, the awareness for the negative health effect from working with waste was very high. The organizing of the scavenger work is suggested, since it would improve their working environment, income and living conditions. Therefore it should increase their contribution significantly to resource recovery.

To understand variables that link the welfare, livelihood and the watershed is crucial when instituting the integrated watershed management. This requires having indicators to show changes of the condition of the welfare, livelihoods and watershed resources. However, the combination of livelihoods and welfare of the local communities who depend largely on watershed resources for income, food, energy and shelter have not been adequately considered elsewhere. This results to the imbalance between the human development and the conservation priorities when implementing watershed management policies. The aim of this paper is to present the technical efficiency indicator (TEI) constructed from socioeconomic and watershed related variables. The stochastic frontier analysis (SFA) is employed to construct the TEI. The novelty in the current study is its ability to combine socioeconomic and biophysical information to obtain a sustainability indicator of both the natural resource supporting people’s livelihoods and the welfare of people. The construction of TEI fills the knowledge gap on how to achieve the mutual balance between human development and conservation objectives in the natural resource management arena. Study findings are that there is significant household dependence on the watershed resources. This implies that watershed resources have a greater role to play on the welfare of the communities due to existing direct relationship between crop cultivation and the watershed environment. Therefore there is a need to take into account the sustainability of the watershed resources when setting up development policy in the study area.

Deforestation has an impact on the quality of water flo wing through the watershed and alters the discharge, chemical and physical properties of water. This paper presents the effect of deforestation on water quality, in particular on physical and chemical characteristics of water and evaluates the community based watershed management s chemes in Buyhang micro watershed. The quality of water is assessed on the basis of laboratory analysis of various parameters by using weekly grab samp ling technique fro m three alternative land uses and in depth assessment of farmers' needs, priorities, an d conservation practices. The farmers' primary concerns are food security and sustained productivity. Soil erosion is not seen as a problem in the Cienda commun ity and currently still seems to reflect stable conditions. The perception and appreciation of people towards the function of forest ecosystems is limited. People are continuously changing the forest area for abaca plantations, rice fields, and other agricultural crops in very steep slopes. There is only 0.97 ha of refo restation activity in the watershed. Most people judge the quality of water by its aesthetic properties of colour, taste, odour and turbidity. Except the agricultural water samp les, the other two samp les appeared colourless through visual observations. The water fro m undisturbed forest area is palatable and all are free o f odour. The pH values of the water samples ranged with in standard values. Total hardness was trace except one sample fro m agricultural land. Turbidity was found to be less and ranging from 5 to 22 FTU. Sediment is recorded fro m agricultural water samples and higher during peak flow. The highest concentrations of PO4 - were measured fro m the forest water samples. The mean Ca ++ concentrations ranged from 10 to 11.6 mg/ L. There is no significant difference between the three water samples in Mg ++ concentration. Total K + was also found below 6.6 mg/L. Na concentrations were ranging from 6.5 to 8.7 mg/ L. Generally, the results from this study show no significant difference between waters from forest and deforested area in terms of chemical analysis but clear contrast in physical properties. The nutrient concentration of water fro m the forested site is relatively higher and untypical in the case of n itrate concentratio ns than deforested and agricultural water samples.

The main focus of this paper is the examination of the current trends in the Brazilian Amazon that is promoting significant changes in the standards of economic use involving some rain forest products. Overall, these new trends are demonstrating an extensive modernization of economic activities that affect specially the structure and dynamics of organized communities in this region. On the other hand, these trends also affect the linkage of these communities and their respective networks. In many cases, the type of region network is led by industrial companies. The research also indicates that the main sources of this new process are the market increase of products extracted in the Amazonian biodiversity and, besides this, both scale and level of processing. Finally, it approaches another strategic source of modernization, represented by a closer and effective participation of regional scientific research institutions in these new or ‘emerging systems’.

The purpose of this study was to conduct a quantitative assessment of the CO2-reducing effects of bio-ethanol in its lifecycle, including CO2 emissions generated in the process of ethanol production, and examine its efficacy as an environmental measure. In the study, the significance of the "Bio mass Nippon Strategy", which has been implemented by the Japanese government, as well as the feasibility and economic efficiency of its plan were also discussed. Although the government has set the "revitalizat ion of agriculture, forestry, and fisheries, including farming, mountain, and fishing villages" as a goal for the "Bio mass Nippon Strategy", the results of the study, judging fro m the amount of the subsidy, suggest that the domestic production of ethanol using fallow fields only increases the financial burden on Japanese taxpayers rather than revitalizing the agriculture industry. The results indicate that an emphasis should be placed on the expansion of food production to revitalize the agricultural sector, instead of providing financial support for an ineffective reduction project. If burning by-products from the production of ethanol generates energy, it will increase the rate of CO2 reduction. Ho wever, the domestic production of ethanol and its use proposed in the government's plan are expected to have only limited CO2-reducing effects.

Ho wever, the domestic production of ethanol and its use proposed in the government's plan are expected to have only limited CO2-reducing effects.","PeriodicalId":21136,"journal":{"name":"Resources and Environment","volume":"25 1","pages":"306-316"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85097219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims at investigating the mechanisms of pollutants transport based on geological formations. The study classifies two sub-aquifers groups. The first group are wells which dogged within Senonian Abu Dis format ion, and are mostly used extensively for municipal purposes. The second group are wells dogged with the most top Jerusalem-Hebron formation o f Tu ronian age and mostly used frequently for irrigation purposes. The first group shows a high deteriorated water quality with ionic mo lar ratios bears the ratios fro m Wastewater stagnant in adjacent Zomar stream. The stream bed lays directly over Jerusalem formation wh ich pro motes the pollutant transport directly to the uptake zone. Ho wever, the effect of such stagnant become less in dilut ion time of winter. Septic tanks surrounded these wells are constructed within the top 5 meters of Senonian formation, which mean that the leakage fro m septic tanks is not that ease to significantly affect the groundwater quality. The second group are mostly subjected to direct rainfall infiltration this can be indicated through the higher Sodiu m values which are related to the ion exchange through limestone profile. The results emphasize the need for further procedures to mit igate the pollutants plume migration fro m Wadi to the surrounded environment.
