Agro-climatic suitability and water requirement for Tanzania guineagrass cultivation in the State of Ceará. Repositório Alice
LEMOS, N. L. S.; CAVALCANTE, A. C. R.; SILVA, T. G. F. da; PEZZOPANE, J. R. M.; SANTOS, P. M.; CÂNDIDO, M. J. D..
Abstracts: This study aimed to define areas suitable, and the irrigation water requirement for, cultivation of Tanzania guineagrass in the state of Ceará, Brazil. Tanzania guineagrass yield was estimated by a mathematical model, which considers the crop actual evapotranspiration, resulting from the crop climatological water balance. The water requirement throughout the year was estimated for soils with a water holding capacity of 20 (shallow soils), 40 (sandy soils), 60 (soils with medium texture) and 100 mm (clay soils). The relative frequency of occurrence of monthly productions greater than 2,750 kg DM ha-1 month-1 was obtained for different areas in Ceará, representative of most of the state's economic mesoregions. Tanzania guineagrass annual yields in...

Avaliacao de barreiros e finalidade de agua armazenada na regiao semi-arida da Bahia. Repositório Alice
CAVALCANTI, N. de B.; RESENDE, G. M. de.
Fazer-se um levantamento do tipo e da quntidade de barreiros utilizados pelos pequenos agricultores das comunidades de Curaca, Casa Nova e Jaguarari, municipios do Estado da Bahia, foi a meta principal deste trabalho, realizado no periodo de janeiro de 1998 a dezembro de 1999, em que os resultados obtidos demonstraram que os pequenos agricultores utilizam algum tipo de barreiro para armazenar agua de chuva. A agua e utilizada para o consumo humano e animal.

Inventory of water storage types in the Blue Nile and Volta River Basins AgEcon
Johnston, Robyn M.; McCartney, Matthew P..
For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of...

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.
