Provedor de dados: 70
Autores: Silva,Laércio S.; Galindo,Izabel C. de L.; Gomes,Romário P.; Campos,Milton C. C.; Souza,Edivan R. de; Cunha,José M. da.
ABSTRACT Inadequate and intensive management of soils can promote changes in their chemical attributes and impair the quality of surface and groundwater, especially in hillside areas. Therefore, the aim of this study was to identify possible changes in soil and water chemical composition of hillside areas cultivated with horticulture. For this, chemical attributes of three soil depths (0-10, 10-30, and 30-60 cm) were determined in three hillside positions (upper, middle, and lower thirds) of five hillside and adjacent forest areas, as well as water from reservoirs for agricultural use and human consumption. Compared with the forest area, horticultural areas present soil with lower organic matter content and CEC, but higher values of pH, base saturation,...

Irrigação de pequenas áreas.
Provedor de dados: 14
Autores: PINTO, J. M.
A limitação de recursos hídricos dificulta a produção de alimentos em regiões semiáridas, com distribuição irregular de precipitações pluviométricas. Dessa forma, a otimização desses recursos, captando água de chuva para uso doméstico, para a criação de animais e para a produção de alimentos se torna uma necessidade premente. Outra alternativa é utilizar a água armazenada em pequenas bacias de captação (lagoas, barreiros, pequenos açudes) que se formam durante o período chuvoso para cultivos de hortas e pomares. No caso de hortaliças, com espaçamentos pequenos entre plantas, deve-se molhar uma faixa contínua do solo, enquanto em fruteiras, com plantas de maior porte, recomenda-se molhar manchas de solo, aplicando-se uma quantidade menor de água por área,...

Provedor de dados: 31
Autores: Mukherjee,   Sacchidananda; Nelliyat,   Prakash.
Industrial disposal of effluents on land and the subsequent pollution of groundwater and soil of surrounding farmlands – is a relatively new area of research. The environmental and socioeconomic aspects of industrial effluent irrigation have not been studied as extensively as domestic sewage based irrigation practices, at least for a developing country like India. The disposal of effluents on land has become a regular practice for some industries. Industries located in Mettupalayam Taluk, Tamil Nadu, dispose their effluents on land, and the farmers of the adjacent farmlands have complained that their shallow open wells get polluted and also the salt content of the soil has started building up slowly. This study attempts to capture the environmental and...

Planning groundwater use for sustainable rural development
Provedor de dados: 31
Autores: 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.

Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa
Provedor de dados: 31
Autores: McCartney,   Matthew P.; Arranz,   Roberto.
Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were...

Farming communities in water-scarce regions increasingly practice the use of urban wastewater in agriculture. Untreated urban wastewater is generally considered unacceptable for direct use because of potential health risks. However, in many parts of the world, poor farmers in peri-urban areas use untreated wastewater. This situation is considered likely to continue even in the foreseeable future due to the high investment cost associated with the installation of treatment facilities.

Institutional perspectives of land reclamation operations in Punjab: A case study of the Lower Chenab Canal (East) Circle Area
Provedor de dados: 31
Autores: Bandaragoda,   Don Jayatissa; Rehman,   Saeed ur.
The Directorate of Land Reclamation (DLR), which was set up in 1945, is a special unit of Punjab's Irrigation and Power Department for undertaking research and field operations to combat the problem of salinity.  Approaching the end of five decades of existence, the directorate is yet to demonstrate its effectiveness in its assigned task; its inability to fully cope with the conditions of a fast changing irrigation environment makes this rather an illusive goal. In the selection of lands for reclamation, the Directorate is heavily dependent on the visual salinity survey (Thur Girdawari) carried out every year by the Irrigation Department's field staff.  This visual survey appears to be a quick and cost-effective method of assessing surface salinity, but...

Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&amp;M (operation &amp; maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water...

India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.

Effect of changes in the institutional structure of irrigation water property rights on the willingness to pay of farmers for water: case of Tunisia
Provedor de dados: 31
Autores: Frija,   Aymen; Chebil,   Ali; Speelman,   Stijn; Van Huylenbroeck,   Guido.
This paper assesses the economic value of changes in the attributes of farmers’ irrigation water property rights in Tunisia. Changes on attributes generated by the transfer process of the property rights from the collective to the individual level in addition to changes in “constitutional” attributes were integrated into three scenarios. The valuation was conducted using the Contingent Valuation Method through the elicitation of individuals’ willingness to pay. Results show positive willingness to pay values for all scenarios. However, farmers of the studied region are shown willing to pay more for changes in the constitutional attributes. Furthermore their willingness to pay appears to be most affected by their perceptions concerning the organization and...

Hygienic-sanitary conditions of vegetables and irrigation water from kitchen gardens in the municipality of Campinas, SP
Provedor de dados: 58
Autores: Simões,Marise; Pisani,Beatriz; Marques,Eneida Gonçalves Lemes; Prandi,Maria Angela Garnica; Martini,Maria Helena; Chiarini,Paulo Flávio Teixeira; Antunes,José Leopoldo Ferreira; Nogueira,Ana Paula.
We examined samples of irrigation water and vegetables from kitchen gardens in Campinas, Brazil. The bacterial analysis condemned 22.3% of the vegetable samples, and the parasitological examination condemned 14.5%.
