A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia AgEcon
Makombe, Godswill; Namara, Regassa E.; Hagos, Fitsum; Awulachew, Seleshi Bekele; Ayana, Mekonnen; Bossio, Deborah A..
Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

A gender performance indicator for irrigation: Concepts, tools and applications AgEcon
van Koppen, Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

A plot of one's own: gender relations and irrigated land allocation policies in Burkina Faso AgEcon
Zwarteveen, Margreet Z..
Discusses the potential opportunities and pitfalls of introducing market forces into the process of water allocation. Proposes several preconditions for beneficial privatization of water allocation and argues for a more sophisticated form of analysis than that generally allowed by proponents of basic needs or of free market approaches.

Az öntözéses gazdálkodásról a Tisza-tó és a nagykunsági öntözőrendszert ellátó főcsatorna átadásának 30. évfordulóján AgEcon
Lengyel, Lajos.
Az öntözés mint agrotechnikai tényező a mezőgazdasági termelés intenzifi kálásának egyik eszköze és lehetősége. Bevezetése többletberuházással, nagyobb ráfordításokkal oldható meg. Öntözéssel a természetes csapadékellátás ingadozásai csökkenthetők, a termelés biztonsága és a hozamok növelhetők. Alkalmazását az üzemi feltételek és célok mellett makrogazdasági és klimatikus hatások is indokolják. Az elmúlt fél évszázad hazai öntözésfejlesztésében a Tiszalöki, a Kiskörei Vízlépcső és Öntözőrendszerei tervezése, kivitelezése és működtetése napjainkban is sok hasznosítható tanulsággal és tapasztalattal szolgál, mint például a komplex szemléletű térségi, üzemi vízgazdálkodás és öntözésfejlesztés, az állami beavatkozás a tervek összehangolásától az üzemi...

Basin-level use and productivity of water: examples from South Asia AgEcon
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.

“Bright spots” in Uzbekistan, reversing land and water degradation while improving livelihoods: Key developments and sustaining ingredients for transition economies of the former Soviet Union AgEcon
Noble, Andrew D.; Ul Hassan, Mehmood; Kazbekov, Jusipbek.
Following the dissolution of the former Soviet Union and the collapse of existing trade arrangements, the newly independent states of Central Asia were left with the task of developing their own independent market economies. The region has undergone tremendous economic and social changes including significant agricultural reform mainly targeted at privatizing large collective farms that were established during the Soviet era. These reforms include the establishment of smaller private and cooperative farms in order to improve the efficiency and equity of existing production systems. Within Uzbekistan, this move to privatize farms has, in the majority of cases, led to declining productivity and net incomes. However, there have been instances where privatized...

Cevada irrigada em áreas de Cerrado no Brasil Central. Infoteca-e
AMABILE, R. F.; SILVA D. B. da; GUERRA, A. F..
ABSTRACT: This work shows the importance of barley as an alternative crop to integrate production systems in the Brazilian Savanna. It is an economical option for the farmer, in opposition to the traditional crops of common bean and wheat. Barley hass been adapted to the climatic conditions of the area, with high yielding potential. Cultivar BRS 180 - the first barley for brewing, has a six row spike and is recommended for dry season cultivation, when it is disease free and performs the best.

Comportamento de cultivares de arroz irrigado sob regime de sequeiro favorecido, em Rio Branco-Acre. Infoteca-e
CAMPOS, I. S.; MEDEIROS, J. A..
As cultivares atualmente plantadas na região apresentam porte alto, principalmente quando cultivadas em áreas de matas recém desbravadas e espaçamento reduzido, o que favorece o acamamento. um dos principais problemas da orizicultura acreana. Os trabalhos de introdução de material genético para as condições do Estado do Acre, não tem apresentado resultados satisfatórios, possivelmente, pelo fato desse material ter sido desenvolvido em região de clima, solo e cultivo, diferentes das condições desse Estado. Partindo de 30 cultivares provenientes do Centro de Pesquisa Agropecuária do Trópico Úmido (CPATU), foi conduzido um ensaio no campo experimental da EMBRAPA/UEPAE-Rio Branco, no ano agrícola 19801/81, em área de terra firme, de Latossolo Amarelo, textura...

PEREIRA, M. C. T.; SALOMAO, L. C. C.; SILVA, S. de O. e; SEDIYAMA, C. S.; COUTO, F. A.; SILVA NETO, S.P. da.
Este estudo teve por objetivo verificar o comportamento da bananeira (Musa spp.) 'Prata Anã' no primeiro ciclo de produção na localidade de Jaíba, MG, submetida a sete espaçamentos, com irrigação. Os tratamentos foram: triângulo: 2,7 m x 3,2 m (1.157 covas/ha) e 2,9 m x 3,4 m (1.014 covas/ha); fileira dupla em triângulo: 4,5 m x 2,0 m x 3,0 m (1.026 covas/ha) e 4,5 m x 2,0 m x 2,0 m (1.538 covas/ha); fileira dupla em retângulo: ,5 m x 2,0 m x 3,5 m (879 covas/ha); e retângulo: 4,0 m x 2,0 m (1.250 covas/ha) e 3,0 m x 2,0 m (1.666 covas/ha). Os sistemas de espaçamento e as densidades populacionais testados não alteraram as taxas de rescimento das plantas nem suas características na época da colheita. Entretanto, as bananeiras plantadas em maiores densidades...

Emissão diária de gases de efeito estufa em sistema de produção de arroz irrigado. Repositório Alice
VIEIRA, S. P.; GALVAO, J. A. H.; VILLELA, O. V.; LUIZ, A. J. B.; LIMA, M. A. de.
Resumo: Mensurações locais são fundamentais a o aprimoramento de estimativas de emissão de gases de efeito estufa (GEE) no setor agropecuário, bem como à redução das incertezas em inventários nacionais. Neste sentido, estudos de avaliação da emissão diária de GEE constituem uma ferramenta importante às estimativas regionais por permitir a identificação de horários ou mesmo períodos mais representativos da ocorrência de emissões médias, otimizando os esforços de mensuração em campo. O objetivo deste estudo foi avaliar emissões diárias de GEE em sistema de produção de arroz irrigado na APTA/Polo Vale do Paraíba, em Pindamonhangaba, SP, com vistas à determinação de horários representativos de emissão média diária e sua correlação com variáveis ambientais....
