A preliminary study on solid waste generation at Har Ki Pauri,Haridwar, around the Ardh-Kumbh period of sacred bathing in the river Ganga in 2004

The amount of solid waste in the vicinity of the river Ganga increased rapidly during the festive days of Ardh-Kumbh. The initial amount of solid waste was 775.0 kg, observed on 30th January 2004 in the Har Ki Pauri area, which increased to 4,550.0 kg on the main bathing day of 4th May 2004, showing nearly a six-fold increase. The total amount of solid waste collected during nine days of observations was 23,865.0 kg. The rate of solid waste generation fell sharply during the following week, after the main bathing day, and was found to be 1,155.0 kg, which is still about 14.90% higher than the initial value.     

The hardrock minerals industry and the landscape architect

The landscape architecture profession is a source of creative thinking and planning which is relatively untapped within the mining industry in the United States of America. The landscape architect has been active in European operations for years as indicated by the four examples presented. The landscape architect can provide an important interface with mine design and engineering and environmental affairs. To initiate this interface within the United States, and increase its effectiveness, six objectives are presented and discussed.     

Fuelwood use by different tribal and non-tribal communities in north-east India

This paper analyses the fuelwood consumption pattern by different tribal and non-tribal communities ofMeghalaya in north-east India. The total fuelwood consumption including all activities such as cooking, rice beer preparation, room and water heating and festival celebration, ranged from 4.7 kg/capita/day for the Garos to 2.1 kg/capita/day for the Nepalese. The total energy expended for fuelwood collection was highest for the Nepalese (0.23 MJ/capital day) and least for the Garos (0.12 MJ/capital day). The present information on fuelwood consumption patterns by different tribal and non-tribal communities could form the basis for designing appropriate technologies for energy plantations in the region. Besides this, some other technologies such as the introduction of fuel efficient devices at the village level and recycling of resources through biogas could be appropriate.     

Edaphological characteristics of unweathered and weathered fly ashes from Gondwana and lignite coal

Naturally weathered and unweathered samples of fly ashes produced from Gondwana and lignite coals were characterized for their edaphological properties. The particle size distribution in these fly ashes varied widely, and the percentage of [Formula: see text] size particles governed their water holding capacity. All fly ashes were noncoherent in the dry state and had lower particle density than quartz and mulite. The fly ashes were low in available N, but were sufficient in available P, K, Ca, Mg, S, Cu, Fe, Mn, Zn and B. Among the fly ashes, unweathered lignite fly ash was the richest source of K, Ca, Mg, S and Fe, while weathered lignite fly ash had the highest amounts of Mn, Zn and B. The pH of the fly ashes was closely related to the ratio of exchangeable Ca to exchangeable Al. The fly ashes were high in soluble salt, but were poor in cation exchange capacity. As an amendment to correct soil pH, the fly ashes had a poor buffering capacity. Weathering decreased the total Fe, available S and exchangeable Na percentages, but increased the organic C content of the fly ashes. Invariably, an excess of soluble salts and exchangeable Na could limit plant growth on fly ash dumps. Toxic levels of B and Al existed in only some fly ashes.     

Chorionic villus sampling utilization following reports of a possible association with fetal limb defects

Prenatal diagnosis choices were reviewed in 473 women who presented for genetic counselling prior to 11 weeks' gestation for the indication of advanced maternal age. Group A consisted of 336 patients who were unaware of a possible association between chorionic villus sampling (CVS) and limb defects. Group B consisted of 137 patients who were provided this information. Fifty-one per cent of patients in group A and 45 per cent of patients in group B chose CVS. This difference was not significant by χ² analysis (P = 0·7). Patterns of prenatal diagnosis procedure utilization from 1987 to 1992 revealed a significant reduction in CVS utilization accompanied by a corresponding increase in amniocentesis after the association between CVS and limb defects was publicized. Referrals for CVS counselling also significantly declined. However, acceptance rates did not change for those patients who received genetic counselling. First-trimester genetic counselling, including a discussion regarding a possible association between CVS and limb defects, helps patients make informed decisions concerning prenatal diagnosis options, and, in our population, resulted in no change in CVS acceptance rates.     

Socio-economic impact management: programme design and implementation considerations

While larger mineral resource development projects offer new jobs and provide a stimulus to the economy of the area where they are sited, they may also pose problems in rural areas associated with rapid population growth. The purpose of an impact management programme is to anticipate and alleviate project effects that are generally perceived as undesirable and to enhance effects that are beneficial to site area communities. While the effective management of project effects is the end towards which all impact assessment efforts are directed, an integrated approach to impact management has been notably lacking. This paper suggests a systems framework for meeting this need by: (1) reviewing the need for impact management efforts; (2) discussing the objectives of, and considerations in, designing impact management programmes; (3) presenting a conceptual framework for, and key components of, such a programme; and (4) suggesting an approach for implementing such a system as an integral part of the project development process.     

White-tailed deer movement and distribution about surface coal mines in West Virginia,USA

Deer movements around surface coal mines were investigated in Preston Country, West Virginia, USA. Seventy-two deer crossings were counted on 29 surface mines with only 8% found on highwalls with more than 20% rock or stone. Thus, although slope was important, the percentage of dirt on the highwall determined use as a crossing location for deer. The average distance between all deer crossing was 209.7 m but the distance between the end of the highwall and the nearest highwall crossing was 248.7 m indicating reluctance of deer to cross mines when they could walk around them. Winter snow track counts showed fewer deer within 90 m of the top edge of the highwall. Four land bridges traversed the highwall and were heavily utilized by deer, especially in March, April, May, October and November. The surface mine bench was used as a fawn bedding area, but little feeding occurred on this portion of the mine.     

A field test of processed oil shale reclamation strategies designed for minimal use of limited resources

Reclamation of processed oil shale disposal areas in the arid and semi-arid regions of Utah, Colorado and Wyoming faces several challenging problems. Shallow topsoil, harsh climate and limited water supply and low suitability of processed oil shale as a plant growth medium must be addressed if any reclamation plan is to be successful.A prototype reclamation plan that addressed the harsh environmental conditions was proposed early in the development of oil shale in eastern Utah. Studies to validate the reclamation plan were initiated in 1978 on a simulated oil shale disposal area at Anvil Points, Colorado.Four native shrubs, one forb and a grass, were successfully established by planting container-grown transplants into a topsoil-filled V-shaped trench. Supplemental water was provided from an adjacent water harvesting slope. The roots of the transplanted species grew into the adjacent shale from the soil trench, thus indicating their adaptability to the adverse oil shale conditions.Support for this research was provided by the White River Shale Corporation, Salt Lake City, Utah.
