Última Cenário mundial dos recursos hídricos subterrâneos. Repositório Alice GOMES, M. A. F.; PEREIRA, L. C.. Resumo: A escassez de água para consumo humano se faz presente em todo Planeta, representando um risco iminente para a sobrevivência da população mundial, sobretudo para aquela de países menos desenvolvidos. Como as águas superficiais têm sido as mais afetadas, seja pela disponibilidade reduzida, seja pela qualidade cada vez mais crítica, a busca pelas águas subterrâneas tem sido intensificada nas duas últimas décadas, tornando-as também escassas em vários países. Frente a esse cenário de degradação, torna-se urgente a adoção de medidas e ações que viabilizem a proteção dos mananciais subterrâneos, denominados aquíferos. Assim, o presente trabalho faz uma descrição e uma análise crítica desse cenário atual, abordando a situação dos principais aquíferos do...

A.; FROEHNER, S.; PALAGANO, L. T.; ROSA FILHO, E. F. da. A vulnerabilidade de aquíferos do tipo cársticos à contaminação por atividades agropecuárias ocorre em função de sua estrutura geomorfológica. No entanto, existem poucos estudos desta natureza no Brasil. O objetivo deste estudo foi avaliar a ocorrência de nitrato, bactérias coliformes e atrazina em poços rasos e profundos no aquífero cárstico paranaense sob influência de atividades agrícolas. O estudo foi realizado em uma área de agricultura intensiva sobre aquífero cárstico da bacia hidrográfica do Alto Iguaçu/Ribeira no município de Colombo-PR. As campanhas amostrais foram realizadas no período entre 2014 e 2015 em 15 poços rasos e 7 poços profundos, para análise bacteriológica, de NO3- e de atrazina na água. A concentração de NO3- nos poços rasos variou...

Ano: 2017 URL: http://www.alice.cnptia.embrapa.br/alice/handle/doc/1078921 Groundwater policy: issues and alternatives in India AgEcon Moench, Marcus. This paper reviews policy-related issues discussed in recent conferences that will affect groundwater development and management efforts in South Asia. Emphasis is given to policy issues surrounding emerging groundwater depletion and quality concerns, and issues concerning the equitable development of groundwater for poverty alleviation. The paper outlines the range of services that depend on groundwater resources and outlines the range of services that depend on groundwater resources to provide these services, and the complications stemming from the fragmented approach taken to water management throughout the region. A range of responses dealing with the management of the physical system is identified. In conclusion , the paper discusses institutional...

Dinesh; Nagar, Rashmi K.; Singh, Mahendra. An assessment of the social impact of treadle pump technology for manual irrigation in eastern India, the Nepal Terai, and Bangladesh, South Asia's so-called "poverty square." Treadle pump technology can be a powerful tool for poverty reduction in this region. It "self-selects" the poor, and puts to productive use the region's vast surplus family labor. It is claimed that the treadle pump could raise the annual net household income by US$100, on the average.

Ano: 2000 URL: http://purl.umn.edu/44571 Planning groundwater use for sustainable rural development AgEcon International Water Management Institute (IWMI). Groundwater use is rapidly increasing in Sri Lanka, bringing several benefits to small farmers—by allowing them to grow more crops, minimize the impact of droughts, and profit from selling high-value produce. But how can this be sustained? Lessons learned from other countries with longer histories of groundwater use can help policymakers, planners, and development organizations avoid the pitfalls and dangers of indiscriminate use, and capture the benefits that groundwater can bring.

Ano: 2005 URL: http://purl.umn.edu/113019 Policies drain the North China Plain: Agricultural policy and groundwater depletion in Luancheng County, 1949-2000 AgEcon Kendy, Eloise; Molden, David J.; Steenhuis, Tammo S.; Liu, Changming; Wang, Jinxia. The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline.

A study was conducted on the productivity and quality analysis of borehole water in Offa and Erin-Ile in Kwara State, and in Ilesa and Osogbo in Osun State, Nigeria.  Productivity of the borehole was carried out by pumping test to determine the discharge from the boreholes sampled.  Data about the boreholes were obtained from Hydrology Department of the Lower Niger River Basin Development Authority Ilorin, Kwara State (LNRBDA) and Rural Water and Environmental Sanitation Agency in Osun State (RUWESA).  Ten boreholes were sampled in Offa out of which seven were working.  Five boreholes in Erin – Ile were sampled out of which four were functional.  21 boreholes were sampled in Ilesa but only thirteen were working and three boreholes in Osogbo but only one...

Ano: 2012 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/2141 Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability AgEcon Barry, Boubacar; Kortatsi, Benony; Forkuor, Gerald; Gumma, Murali Krishna; Namara, Regassa E.; Rebelo, Lisa-Maria; van den Berg, Joost; Laube, Wolfram. The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.

Ano: 2010 URL: http://purl.umn.edu/112969 The global groundwater situation: overview of opportunities and challenges AgEcon Shah, Tushaar; Molden, David J.; Sakthivadivel, Ramasamy; Seckler, David. Groundwater offers us few but precious opportunities for alleviating the misery of the poor; but it poses many—and daunting—challenges of preserving the resource itself. A big part of the answer is massive initiatives to augment groundwater recharge in regions suffering depletion; but, in the ultimate analysis, these cannot work without appropriate demand-side interventions. The water vision of a world that future generations will inherit will have to be the one in which groundwater plays its full developmental, productive and environmental role but in a sustainable manner; and the framework of action to realize this vision will mean eschewing the current free-for-all in groundwater appropriation and use, and promoting a more responsible management of this...

Ano: 2005 URL: http://purl.umn.edu/118303 Water scarcity and the role of storage in development AgEcon Keller, Andrew; Sakthivadivel, Ramasamy; Seckler, David. Of the four major ways of storing water -in the soil profile, in underground aquifers, in small reservoirs, and in large reservoirs behind dams-the first is possible only for relatively short periods of time. In this paper, the authors concentrate on the three kinds of long-term technologies, and compare the hydrological, operational, economic and environmental aspects of each.
