Oak processionary moth (Thaumetopoea processionea) or OPM was accidentally introduced into London on imported oak trees and now poses a threat to the future of oak in the urban landscape. Early attempts at eradication of the moth failed and significant resources have since been spent by government on monitoring and controlling OPM (through the use of insecticides or bio-pesticides) as it spreads into new areas. OPM is regulated in the UK to minimize risk of new introductions and reduce spread. Surveying for OPM and issuing of statutory notices for control is based on a geographical system of core, control and protected zones. While OPM will defoliate the trees leaving them vulnerable to other pests and diseases and stress factors, the caterpillars can also harm people and animals via tiny urticating hairs with the potential for dermatological or respiratory impacts. However, the biggest threat to the iconic British oak may be that the perceived risks associated with OPM, and costs of management may lead land managers to fell their oak trees, and not plant oak in the future. There is a need to better understand awareness, risk perceptions and decision-making around OPM management. We use a conceptual framework to explore decision-making and the trade-offs between the social, economic and ecological values associated with oak trees, and assessment of risk related to both the moth and control options. Twenty nine interviews were conducted in two London boroughs and across Greater London and in some surrounding counties covering a range of land types (e.g., parks, school grounds, amenity areas and private gardens) with infested or non-infested oak. We found a lack of evidence of human health impacts from OPM although land managers were concerned about public duty of care and potential reputational damage if they do not manage OPM. To address the challenges of dealing with OPM, land managers were taking a risk-based approach and managing OPM where it posed the highest potential risk to people. Respondents expressed strong emotional attachments to oak but it also has high biodiversity value which can lead to difficult decisions about management options. A risk-based approach moves beyond a ‘one-size-fits-all’ control method and focuses available resources where they are most needed and socially acceptable. An approach that allows for multiple values and perspectives on risk may provide a more sustainable long-term option for OPM management to ensure the future of oak in the city.

The study assessed the effect of the urban environmental stress on the subjective well-being of the people in Bhopal city of India. The objectives were to assess the perceived urban environmental stressors and to explore the coping strategies adopted by the people to combat the outcomes of Urban Environmental Stress. Perceived Urban Environmental stressors’ Scale (UES) and Urban Hassle Index were administered. The findings indicated that though people described their city as pleasant, a high level of stress was still perceived and its major reasons were found to be noise, waste accumulation, polluted air with smoke, and unhealthy environment in slums. The outcome of research suggests that the city planners should give equal priority to the natural resources and environment by various pollution management interventions and proper city planning. It is crucial for the well-being of the human beings to lower down the effect of stressors, so that the life in the city can be livable and of good quality. This paper provided guidelines for other metropolitan cities too for developing Environmental Competence and for generating mass awareness about the Urban Environmental Stress and its possible management options to help people develop Environmental Resilience and functional coping.

The rapid economic growth and urbanization in Ethiopia have led to extensive construction activities in major cities. Construction activities have known to generate large quantities of wastes that pose serious environmental problems. This paper presents the challenges of construction waste management practices in Mekelle city and explores appropriate measures to address the issues in a more sustainable way. Field observation, questionnaire survey, interviewing of public sector officials at different levels was conducted to identify the source and management options of construction waste in the city. The findings showed that the majority of survey participants felt that their firms have taken various measures to manage construction waste. It was revealed that 40% of the respondents exercise illegal dumping as a common method of waste management, which is closely followed by reuse and recycling. It is evident that over 75% of the construction- generated has potential for recycling and reuse as backfilling and base for roads and buildings. The increase in the number of illegal dumping sites in the city represents the failure to properly control and implement effective construction waste management. It was suggested that sustainable solution for construction waste management at local level depends on increasing awareness and promoting reusing and recycling of construction waste.

ABSTRACT: The correct nutrition by the occasion of implantation is essential for the increasing and maintaining the productivity of the planted forests and one of the management options used to minimize the effects of variability in productivity is the precision agriculture, which with the use of geostatistical tools aid in the management of the crop and represents an important factor in the economy and more rational employment of agricultural inputs. The aim of this study was to evaluate the influence of liming on the spatial variability of leaf chemical composition (N, P, K, Ca, Mg and S) and at the height of the spontaneous hybrid of Eucalyptus urophylla clone I 144, at six months after planting, in a Quartzarenic Neosol in a low altitude cerrado zone. The experiment was conducted in an area belonging to the Bom Retiro Farm, property of Eldorado Brazil Celulose, between the months of March to September 2014, located in the city of Água Clara, MS. The geostatistical mesh installed in a regular grid for data collection was comprised of 50 points with a sample spacing of 9.0 x 7.5 m. The studied attributes were the plant height and leaf nutrient content (N, P, K, Ca, Mg and S) of the eucalyptus. The data were analyzed by descriptive statistics and spatial variability was determined by geostatistical methods such as calculating the semivariogram and use of interpolated maps by ordinary kriging. The liming had influenced the leaf content of nitrogen, phosphorus, calcium and magnesium of Eucalyptus urophylla clone I 144 and the leaf magnesium was the only attribute that presented spatial dependence, which enables the management located at an early stage.Key words: geostatistics, eucalyptus nutrition, limestone, precision agriculture. INFLUÊNCIA DA CALAGEM NA VARIABILIDADE ESPACIAL DA COMPOSIÇÃO QUÍMICA FOLIAR E NO CRESCIMENTO INICIAL DO EUCALIPTO RESUMO: A correta nutrição por ocasião da implantação é essencial para o aumento e manutenção da produtividade das florestas implantadas e uma das opções de manejo utilizadas para minimizar os efeitos da variabilidade na produtividade é a agricultura de precisão, que com o uso de ferramentas geoestatísticas auxiliam no manejo da lavoura e representa fator importante na economia e emprego mais racional dos insumos agrícolas. O objetivo deste trabalho foi avaliar a influência da calagem na variabilidade espacial da composição química foliar (N, P, K, Ca, Mg e S) e na altura do híbrido espontâneo de Eucalyptus urophylla clone I 144, aos seis meses após o plantio, num Neossolo Quartzarênico em área de cerrado de baixa altitude. O experimento foi conduzido em área pertencente à Fazenda Bom Retiro, propriedade da Eldorado Brasil Celulose, entre os meses de março a setembro de 2014, localizada no munícipio de Água Clara, MS.

Abstract One of the many challenges municipalities in the Great Lakes Remedial Action Plan (RAP) areas must face is the lack of a screening tool to determine stormwater quality management options in their urbanized areas. In support of the RAP process, Environment Canada, through the Great Lakes 2000 Cleanup Fund, the Ontario Ministry of Environment and Energy, and the City of Scarborough, commissioned Ryerson Polytechnic University to develop a generic planning strategy for stormwater quality management in urbanized areas. The generic planning strategy comprises five steps: (1) identification of ecosystem and economic goals and objectives; (2) identification of feasible retrofit stormwater management practices (RSWMPs); (3) formulation of alternative stormwater quality management strategies in accordance with a preferred hierarchy of RSWMPs; (4) evaluation of alternative strategies with respect to cost-effectiveness; and (5) selection of a stormwater quality management strategy. To demonstrate the application of the generic planning strategy, a stormwater quality management plan was developed for the Centennial Subwatershed (730 hectares) in the City of Scarborough, which is fully urbanized. Using the generic planning strategy, the recommended stormwater quality plan assumes (1) all the roads in poor condition will be retrofitted with stormwater exfiltration systems as they are reconstructed or rehabilitated; (2) an existing quantity pond will be retrofitted with a water quality function; (3) a new water quality pond will be constructed on a government-owned site; (4) 50% of the feasible residential areas will have downspouts disconnected; and (5) all the roads in the feasible commercial areas will be retrofitted with oil/grit separators. The average annual runoff volume reduction and solids loading reduction of this strategy were estimated to be about 9 and 30%, respectively, and the associated cost was about $1.2 million.
