Provedor de dados: 70
Autores: Rosa,Jadir A.
With the objective to stimulate the use of irrigation and the electric energy fee reduction during night time program granted by the 2004 Federal law, the Government of the state of Paraná, Brazil launched the Night Irrigation Program - NPI. Beyond this discount, the farmer that adheres to NPI will get additional benefits, as completion of the electric grid without cost, subsidized financing of equipment, technical assistance, support with environmental farm compliance, and the possibility of replacing the entire pump energy matrix. As part of the NPI strategy of action, installation of learning centers for irrigation technology was planned in agricultural schools, thus contributing both to improve technical professional training in agriculture, and for...

Taking a multiple-use approach to meeting the water needs of poor communities brings multiple benefits
Provedor de dados: 31
Autores: International Water Management Institute (IWMI); International Water and Sanitation Centre; Global Water Partnership (GWP).
This briefing was produced by International Water Management Institute (IWMI), the IRC International Water and Sanitation Centre, the Technical Committee of the Global Water Partnership (GWP) and the GWP Advisory Center at IWMI. It draws primarily on research from the Multiple Use Systems (MUS) project and the Productive Uses of Water Thematic Group (Prodwat) (see references for further reading). The brief complements Catalyzing Change, the GWP handbook for developing IWRM and water efficiency strategies and plans, and the associated policy and technical briefs. Single-use approaches to water development and management do not reflect the realities of poor people’s water use. People use domestic water supplies for activities such as irrigating backyard...

Economics and politics of water resources development: Uda Walawe Irrigation Project, Sri Lanka
Provedor de dados: 31
Autores: Molle,   Francois; Renwick,   Mary E.
The Uda Walawe Irrigation and Resettlement Project (UWIRP) located in the Southern dry zone of Sri Lanka was initiated in the early 1950s. The original plan for the UWIRP was a highly ambitious social, economic and physical engineering project aimed at creating a modern, profitable agriculture sector. This report examines the history of water resources development and investment decisions for the UWIRP over a period of 50 years and uncovers underlying processes that shaped the evolution of the project and highlights the limitation of viewing development as a mere set of technical and social engineering endeavors.

Does anybody give a dam? The importance of public awareness for urban water conservation during drought
Provedor de dados: 31
Autores: Aisbett,   Emma; Steinhauser,   Ralf.
Demand management has been of interest in dry climates such as Australia, Spain and the Western United States for decades. It is particularly important to understand policy options during drought conditions, as drought periods have a disproportionate effect on supply infrastructure decisions. While water‐conservation campaigns aimed at inducing voluntary consumption reductions are almost universally employed by water managers in times of supply constraint, voluntary measures are generally dismissed in the economics literature as ineffective. We argue that the robust positive correlation between dam levels and consumption after controlling for policy changes suggests that there is a significant component of voluntary conservation. Furthermore, omitting dam...

Economic Change and Environmental Issues: Policy Reforms and Concerns in Australian Agriculture
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Since the closing years of the 1980s, Australia has adopted structural adjustment policies designed to foster economic liberalism based on the market system.  Today, there is little economic protection for Australian agriculture and Australia is a persistent advocate of free international agricultural trade.  The natural Australian environment is not very favourable for agriculture because of low and erratic levels of rainfall and poor soils.  Scarcity of water in Australia is growing and its use has become a major natural resource issue.  Water availability and use of water by Australian agriculture is discussed, its environmental impacts are considered and the scope for using market systems to allocate water effectively are discussed.  Other...

Ethanol and a Changing Agricultural Landscape
Provedor de dados: 31
Autores: Malcolm,   Scott A.; Aillery,   Marcel P.; Weinberg,   Marca.
The Energy Independence and Security Act (EISA) of 2007 established specific targets for the production of biofuel in the United States. Until advanced technologies become commercially viable, meeting these targets will increase demand for traditional agricultural commodities used to produce ethanol, resulting in land-use, production, and price changes throughout the farm sector. This report summarizes the estimated effects of meeting the EISA targets for 2015 on regional agricultural production and the environment. Meeting EISA targets for ethanol production is estimated to expand U.S. cropped acreage by nearly 5 million acres by 2015, an increase of 1.6 percent over what would otherwise be expected. Much of the growth comes from corn acreage, which...

Provedor de dados: 31
Autores: Molden,   David J.; Sakthivadivel,   Ramasamy; Habib,   Zaigham.
Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

Impact of Zero Tillage in India's Rice-Wheat Systems
Provedor de dados: 31
Autores: Laxmi,   Vijay; Erenstein,   Olaf; Gupta,   Raj K.
To date, the most widely adopted resource conserving technology (RCT) in the Indo-Gangetic Plains (IGP)has been zero-tillage (ZT) for wheat after rice, particularly in India. This report reviews and synthesizes the experience with zero tillage in the Indian IGP. Zero tillage of wheat after rice generates significant benefits at the farm level, both in terms of significant yield gains (6–10%, particularly due to timelier planting of wheat) and cost savings (5–10%, particularly tillage savings). These benefits explain the widespread interest of farmers and the rapidity of the diffusion across the Indian IGP, further aided by the wide applicability of this mechanical innovation. The study  subsequently reports on the findings of village-level focus-group...

Bailout with white revolution or sink deeper?: groundwater depletion and impacts in the Moga District of Punjab, India.
Provedor de dados: 31
Autores: Amarasinghe,   Upali A.; Smakhtin,   Vladimir U.; Sharma,   Bharat R.; Eriyagama,   Nishadi.
Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.

Experiments with regulations &amp; markets linking upstream tree plantations with downstream water users
Provedor de dados: 31
Autores: Nordblom,   Thomas L.; Reeson,   Andrew; Finlayson,   John D.; Hume,   Iain H.; Whitten,   Stuart M.; Kelly,   Jason A.
Land-use change in upper catchments impact downstream water flows. As trees use large amounts of water the expansion of upstream plantations can substantially reduce water availability to downstream users. There can also be impacts on downstream salinity due to reduced dilution flows. In some jurisdictions afforestation requires the purchase of water rights from downstream holders, while in others it does not, effectively handing the water rights to the upstream landholders. We consider the economic efficiency and equity (profitability and distributional) consequences of upstream land use change in the presence of a water market under alternate property rights regimes and different salinity scenarios.

Management of Water Reservoirs (Embungs) in West Timor, Indonesia
Provedor de dados: 31
Autores: Pradhan,   Deepa; Ancev,   Tihomir; Drynan,   Ross G.; Harris,   Michael.
Communal water storage reservoirs (embungs) that serve many villages in West Timor, Indonesia, by providing water during the prolonged annual dry season are experiencing severe sedimentation problems. Sedimentation of reservoirs progressively reduces their water storage capacity and the benefits to community. This paper investigates four alternative strategies for managing the sedimentation of a typical village embung: (1) current management (a “no management” situation), (2) soil conservation in the embung catchment, (3) periodic sediment removal and (4) both soil conservation and sediment removal. Without periodic sediment removal, an embung has a finite life dependent on the rate of sedimentation. The results indicate that periodic cleaning is clearly...

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.

Improved Water Supply in the Ghanaian Volta Basin: Who Uses it and Who Participates in Community Decision-Making?
Provedor de dados: 31
Autores: Engel,   Stefanie; Iskandarani,   Maria; Useche,   Pilar.
We examine access to, use of, and participation in decisions on improved water supply in the Volta basin of Ghana, one of the first countries to introduce a community-based approach to rural water supply on a large scale. While 71 percent of the households interviewed have access to improved water, 43 percent of these continue to use unsafe sources as their main domestic water source. Our results indicate that quality perceptions and opportunity costs play an important role in households’ choice of water source. The effect of prices and income levels on this choice differs according to the pricing system used. Given that supply characteristics such as the location and pricing system affect household decisions to use the improved source, households may try...

Autores: Zomer,   Robert J.; Bossio,   Deborah A.; Trabucco,   Antonio; Yuanjie,   Li; Gupta,   Diwan C.; Singh,   Virendra P.
Trees are increasingly grown on-farm to supply wood and biomass needs within developing countries. Over the last several decades, within the irrigated rice-wheat growing lands of northern India, fast-growing poplar trees have been planted on tens of thousands of small farms. Recent debate regarding afforestation has raised the issue that water use is often increased when trees are planted. This ongoing debate focuses primarily on afforestation or reforestation of upland and rain-fed agricultural areas, and off-site impacts such as reduced streamflow. Adoption of poplar agroforestry in northern India, in contrast, is occurring in areas where land and water are already intensively used and managed for agricultural production. This study based on farmer...

This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and  increasing water...

This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and...

Modelling Water Use in Thailand
Provedor de dados: 31
Autores: Piyanuch,   Wuttisorn; MacAulay,   T. Gordon; Batterham,   Robert L.
In this paper a model is proposed for analysing alternative policies that might be used in allocating water in Thailand. The model used is an integration of farm linear programming models with a spatial equilibrium model, using the so-called price-linked farm and spatial model (Batterham and MacAulay, 1994). A method of linking spatial equilibrium models and linear programming representations of farm models via the demand side as opposed to the supply side is outlined in this paper. A case study is made of the Chao Phraya Delta, an area that is progressively challenged by competing claims for water use and which needs to better allocate water resources.

Provedor de dados: 124
Autores: Matsinhe,Daniel Zefanias; Pereira,Silvio Bueno; Oliveira,Rubens Alves de; Assis,Igor Rodrigues de; Oliveira,Reginaldo Miranda.
ABSTRACT Irrigation has a great importance in the production of food, and it is responsible for consuming a large part of the water used by human activities. This makes the rational management of water use fundamental for sustainable food production. For this purpose, the determination of bulk density is important and needs to be obtained with the simplest, least onerous methods possible, while maintaining precision and accuracy. Therefore, the objective of this work was to evaluate the use of PVC pipes of different dimensions to determine bulk density. For comparison purposes, the volumetric ring, paraffin clod, beaker and excavation methods were also used. Deformed and undisturbed soil samples of different granulometries were collected at the depths of...

Autores: Afzalinia, Sadegh; Dehghanian, Sayed Ibrahim.
Objective of this study was to evaluate the interaction effect of conservation tillage and irrigation methods on the soil properties, crop yield and water productivity in wheat-maize cropping system. A split plot experimental design with three replications was used to conduct this study in Fars province, Iran. Surface irrigation, drip tape irrigation, and sprinkler irrigation were considered as main plots, and no-tillage, reduced tillage, and conventional tillage were considered as sub plots. Results showed that surface irrigation had the maximum wheat yield on average and the maximum maize yield was obtained from drip tape irrigation on average; while, tillage methods had no significant effect on crops yield. Results also indicated that the maximum water...

Autores: Dawit, Meseret; Dinka, Megersa Olumana.
Water shortages due to climate change are becoming a global concern. Hence, improved irrigation technology resulted in water saving and reduce workload of women by ensuring investment returns. This study aims at investigating the effects of the adoption of drip irrigation combined with hand-dug wells on crop water productivity and crop yield of smallholder farmers and their perception of the scheme over two cropping seasons at Haramaya districts, Ethiopia. It was observed that the integrated irrigation system is an efficient and cost-effective method to improve crop productivity. Consequently, the drip irrigation system with water supply from hand-dug wells is recommended as a flexible system that can accommodate a variety of farm sizes and particularly...

Impacts of drought and temperature stress on coffee physiology and production: a review
Provedor de dados: 61
Autores: DaMatta,Fábio M.; Ramalho,José D. Cochicho.
Overall, drought and unfavourable temperatures are the major climatic limitations for coffee production. These limitations are expected to become increasingly important in several coffee growing regions due to the recognized changes in global climate, and also because coffee cultivation has spread towards marginal lands, where water shortage and unfavourable temperatures constitute major constraints to coffee yield. In this review, we examine the impacts of such limitations on the physiology, and consequently on the production of mainly Coffea arabica and C. canephora, which account for about 99 % of the world coffee bean production. The first section deals with climatic factors and the coffee plant’s requirements. The importance of controlling oxidative...
