ABSTRACT This paper presents an overview assessment of solid waste management in Jimeta-Yola the Adamawa state capital, Nigeria. The objective of this paper is to assess the efficiency or otherwise of the agency responsible for waste management in Jimeta-Yola from 2004-2008. The indiscriminate dumping of solid waste that result in water, air and land pollution which have a substantial negative effect on the environment and human health was examined with the view to proffering planning solutions. There is growing trend of unsanitary conditions of waste disposal and management in the study area and this have a negative health implications on the residents. Data for this study were obtained from the Adamawa State Environmental Protection Agency (ASEPA) and relevant literature. Records show that waste are neither sorted nor recycled but dumped in an open dump 3 km away from the city center. The performance of agency regarding waste management was below average as large tonnage of solid waste can be seen at designated dumpsites thereby blocking drainage channels and access road

    ABSTRACT: Water management is an essential feature of any project related with overall development of agriculture. The Soan river catchment in the northwest Himalayas, is fed only by rainwater. Hence, a strategy of rainfed agriculture needs to be developed through water conservation and storage techniques. The Soan is an important river from a soil erosion and water management point of view and detailed economic analysis is needed for any proposal to be implemented in the field. The present study was undertaken to propose an economic analysis of water harvesting structures for the Soan catchment. The purpose of the investigation is to control erosion and conserve water to meet the requirements of supplemental and pre-sowing irrigation for major cereal crops in the area and to maximise agricultural productivity. Benefit/cost ratios ranging from 0.41 to 1.33 are obtained for water harvesting structures of different sizes with estimated life of 25 and 40 years respectively, by taking into account different crop return from maize and wheat.

    ABSTRACT: Water availability has been a matter of concern all over the world. This paper describes the water availability scenario in the state of Santa Catarina, southern Brazil, and evaluates the potential for potable water savings estimated for the residential sector of 62 cities in the state. Water availability in Santa Catarina amounts to about per capita per year, but it is predicted to be lower than per capita per year from 2100 onwards. As for the potential for potable water savings by using rainwater, it is shown that it ranges from 34% to 92% depending on the potable water demand verified in the 62 cities, with an average potential for potable water savings of 69%. Results demonstrate that if there were a government programme to promote potable water savings by rainwater usage, there would be significant potable water savings and a consequent preservation of water resources in the state of Santa Catarina.

    ABSTRACT: Halving the proportion of people without sustainable access to safe drinking water and basic sanitation, is one of the targets of the 7th Millennium Development Goals (MDGs). In South Africa, with its mix of developed and developing regions, 9.7 million (20%) of the people do not have access to adequate water supply and 16 million (33%) lack proper sanitation services. Domestic Rainwater Harvesting (DRWH), which provides water directly to households enables a number of small-scale productive activities, has the potential to supply water even in rural and peri-urban areas that conventional technologies cannot supply. As part of the effort to achieve the MDGs, the South African government has committed itself to provide financial assistance to poor households for the capital cost of rainwater storage tanks and related works in the rural areas. Despite this financial assistance, the legal status of DRWH remains unclear and DRWH is in fact illegal by strict application of the water legislations. Beyond the cost of installation, maintenance and proper use of the DRWH system to ensure its sustainability, there is risk of waterborne diseases. This paper explores challenges to sustainable implementation of DRWH and proposes some interventions which the South African government could implement to overcome them.
