The concern of this paper is a review of the urban environmental degradation and the current approach by the military (environmental task force) in solving the problem. It is based on the experience of a few states in Nigeria. The paper proposes a comprehensive urban planning approach which should be integrated with an awareness campaign. 相似文献

There are some experts who are dealing with research on locally made materials for building in the Ministry of Housing and Works in Nigeria. It has been discovered in the Ministry that lateriate clays can be fired and used for building even two‐storey buildings depending on the firing and the pressure (Ogunbamwo, 1975). The Ministry has constructed a block of bungalows of low‐cost housing units with mud at Ikoyi, off Kingsway Road. No one will know that these houses are mud houses if not at closer inspection. Unfortunately, no effort has been made to continue or improve on this laudable adventure in Nigeria. 相似文献

Differences exist in the spatial structure of cities in both the developed and developing world owing to the contradistinctive nature of their urban growth processes. The structure of Nigerian cities is characterised by the preponderance of mixed land uses resulting primarily due to the organic nature of city growth and more fundamentally, owing to the dynamics of informal urban economic activities. This paper examines mixed land‐use patterns in selected Nigerian cities and appraises their relevance in the general city growth process. By suggesting principles and speculative spatial patterns expressing desirable use combinations, an attempt is made to rationalise the utility of the concept such that its environmental impact is understood and given planning resolution. 相似文献

Zusammenfassung Der WWF (World Wide Fund for Nature), Initiator und Tr?ger des Donau-Karpaten-Programms, besch?ftigt sich seit Beginn des
Kosovo-Konfliktes mit den Auswirkungen der kriegerischen Auseinandersetzungen auf Natur und Mensch und versucht, die Welt?ffentiichkeit
entsprechend zu informieren. Ende Juli 1999 hat der WWF International eine Mission, bestehend aus unabh?ngigen Toxikologinnen
und ?lexperten, an die Donau entsandt. Unter der Leitung von Philip Weller, dem Direktor des WWF Donau-Karpaten-Programms,
wurden drei Tag lang Industriekomplexe besichtigt und Gespr?che mit Betroffenen geführt. Die Reise führte das Team nach Panćevo
und Novi Sad, und damit zu den Schwerpunkten der zerst?rten Chemie- und Petrochemischen Komplexe. In den betroffenen Werken,
HIP AZOTARA, Panćevo und NIS ?lraffinerie, Novi Sad wurde das Team von den jeweiligen Werkleitern geführt. Gespr?che fanden
statt mit dem Bürgermeister von Panćevo und Vertretern des Gesundheitsamtes in Belgrad. Es war dem Team m?glich, Boden- und
Wasserproben zu nehmen und zu analysieren. Damit liegen den Autoren unabh?ngige Analysenergebnisse vor, die es gestatten,
eine erste, orientierende Einsch?tzung der Kontaminationen vorzunehmen.

Previous research showed a regional Cu enrichment of 6 mg kg−1 in the top soil of the Ypres war zone (Belgium), caused by corrosion of WWI shell fragments. Further research was required
since in addition to Cu, also As, Pb, and Zn were used during the manufacturing of ammunition. Therefore, an additional data
collection was conducted in which the initial Cu data set was tripled to 731 data points and extended to eight heavy metals
(As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) which permitted (1) to evaluate the environmental impact of the heavy metals at a regional
scale and (2) to assess their regional spatial occurrence by performing an optimized geostatistical modeling. The results
showed no pollution at a regional scale, but sometimes locally concentrations exceeded the soil sanitation threshold, especially
for Cu, Pb, and Zn. The spatial patterns of Ni and Cr were related to variations in soil texture whereas the occurrences of
Cu and Pb were clearly linked to WWI activities. This difference in spatial behavior was confirmed by an analysis of coregionalization. 相似文献

Protected areas (PAs) are expected to conserve nature and provide ecosystem services in perpetuity, yet widespread protected area downgrading, downsizing, and degazettement (PADDD) may compromise these objectives. Even iconic protected areas are vulnerable to PADDD, although these PADDD events are often unrecognized. We identified 23 enacted and proposed PADDD events within World Natural Heritage Sites and examined the history, context, and consequences of PADDD events in 4 iconic PAs (Yosemite National Park, Arabian Oryx Sanctuary, Yasuní National Park, and Virunga National Park). Based on insights from published research and international workshops, these 4 cases revealed the diverse pressures brought on by competing interests to develop or exploit natural landscapes and the variety of mechanisms that enables PADDD. Knowledge gaps exist in understanding of the conditions through which development pressures translate to PADDD events and their impacts, partially due to a lack of comprehensive PADDD records. Future research priorities should include comprehensive regional and country-level profiles and analysis of risks, impacts, and contextual factors related to PADDD. Policy options to better govern PADDD include improving tracking and reporting of PADDD events, establishing transparent PADDD policy processes, coordinating among legal frameworks, and mitigating negative impacts of PADDD. To support PADDD research and policy reforms, enhanced human and financial capacities are needed to train local researchers and to host publicly accessible data. As the conservation community considers the achievements of Aichi Target 11 and moves toward new biodiversity targets beyond 2020, researchers, practitioners, and policy makers need to work together to better track, assess, and govern PADDD globally. 相似文献

The World Bank has shifted its accountability over the past two decades away from borrowing countries towards external groups, such as advocacy non-governmental organizations (NGOs). One conduit for this external accountability is the environmental impact assessment (EM) process. EIA has both theoretical and practical challenges when applied in developing countries, but is bound by Bank guidelines designed in developed countries. Using the Bujagali Falls Hydropower Project, Uganda as a case study, this paper will demonstrate that the increase in external accountability at the World Bank via EIA has a negative effect on governments and civil society in the South and on global governance. 相似文献

The terrorist attacks of 11 September 2001 (9/11) left workplaces in pressing need of a mental health response capability. Unaddressed emotional sequelae may be devastating to the productivity and economic stability of a company's workforce. In the second year after the attacks, 85 employees of five highly affected agencies participated in 12 focus groups to discuss workplace mental health issues. Managers felt ill prepared to manage the magnitude and the intensity of employees' emotional responses. Rapid return to work, provision of workplace mental health services, and peer support were viewed as contributory to emotional recovery. Formal mental health services provided were perceived as insufficient. Drawing on their post‐9/11 workplace experience, members of these groups identified practical measures that they found helpful in promoting healing outside of professional mental health services. These measures, consistent with many principles of psychological first aid, may be applied by workplace leaders who are not mental health professionals. 相似文献
