What role can information play in improved equity in Pakistan’s irrigation system? Evidence from an experimental game in Punjab Ecology and Society
Bell, Andrew Reid; New York University, Department of Environmental Studies; andrew.reid.bell@nyu.edu; Shah, M. Azeem A.; International Water Management Institute; a.shah@cgiar.org; Anwar, Arif; International Water Management Institute; a.anwar@cgiar.org; Ringler, Claudia; International Food Policy Research Institute; c.ringler@cgiar.org.
The Indus Basin Irrigation System suffers significant inequity in access to surface water across its millions of users. Information, i.e., monitoring and reporting of water availability, may be of value in improving conditions across the basin, and we investigated this via an experimental game of water distribution in Punjab, Pakistan. We found evidence that flow information allowed players to take more effective action to target overuse, and that overall activities that might bring social disapproval were reduced with information. However, we did not find any overall improvement in equity across the system, suggesting that information on its own might not be sufficient to lead to better water distribution among irrigators.

WHEAT CULTIVARS: RESPONSE TO IRRIGATION AND SOWING DATES Scientia Agricola
Klar,A.E.; Hossokawa,T..
This study was carried out in an Alfisol-Oxisol transition sandy-clay texture, using six wheat cultivars (Triticum aestivum, L.): two tall and tolerant to soil aluminium toxicity (BH-1146, and IAC-18), and four semi-dwarf cultivars - Anahuac, IAC-162, IAC-24, and IAC-60 - of which only the first two are sensitive to soil aluminium toxicity. Two minimum soil water potentials (ys) levels were used: 1. watered, when Ys reached about -0.05 MPa; 2. dry, when the water potential reached around -1.5 MPa. Two sowing dates, 05/22/92 and 06/11/92, were used. The results showed that Anahuac and IAC-60 are the most indicated cultivars for the studied region; when irrigated all cultivars presented similar yield level under no irrigation conditions; the irrigation was...

Yield and photosynthetic attributes of sunflower cultivars grown under supplemental irrigation in the semiarid region of the Brazilian Northeast. Repositório Alice
CARVALHO, L. M. de; CARVALHO, H. W. L. de; CARVALHO, C. G. P..
Abstract ? The objective of this work was to identify the sunflower (Helianthus annuus) cultivar with the highest yield potential for cultivation in the semiarid region of the Brazilian Northeast, under field conditions, with supplementary irrigation. Plant photosynthetic performance and yield were determined in field trials. The experiments were carried out in a randomized complete block design with 12 cultivars planted at 0.70x0.30 m. Net photosynthetic rates above 27 μmol m-2 s-1 and average achene yield of 2,364.68 kg ha-1 and oil yield 961.96 of kg ha-1 were determined. This performance was achieved due to: high stomatal conductance in 'Aguara 4', 'BRS 322', and 'CF101', low water loss through transpiration in 'M 734', 'BRS 321', 'BRS 324',...

YIELD RESPONSE FACTOR (KY) FOR WINTER CORN CROP IN THE REGION OF DOURADOS, MS, BRAZIL REA
Silva,Jaqueline A. da; Rezende,Maiara K. A.; Flumignan,Danilton L..
ABSTRACT Plant yield is strongly influenced by the amount of water used by it. In this sense, yield response factor (Ky) allows evaluating the decrease in yield as a function of the evapotranspiration that occurs, which may be an important tool for harvest forecasting. Therefore, this study aimed to determine Ky for winter corn crop grown in the region of Dourados, MS, Brazil. The yield function analysis based on the water factor, which requires actual (Ya) and maximum (Ym) yield data, as well as actual (ETa) and maximum (ETm) evapotranspiration, was used to adjust Ky. Ym was assumed to be 8,820 kg ha−1, while Ya was obtained for each season from the database SIDRA from IBGE. ETm and ETa were estimated by sequential daily water balance, considering four...

A área de influência do canal das vertentes litorâneas da Paraíba (Canal Acauã-Araçagi) possui uma extensão de 5.144 km2, e a maior parte dessa área está inserida nos domínios do Semiárido. O objetivo deste estudo foi avaliar o potencial de terras para irrigação da referida área por meio de uma metodologia desenvolvida neste trabalho. Para estabelecer as classes de terra para irrigação, foi utilizado o Sistema Brasileiro de Classificação de Terras para Irrigação (SiBCTI) com o apoio de um levantamento de solos na escala 1:50.000. O potencial de terras para irrigação foi obtido por meio de regras inéditas de decisão levando em conta as proporções das diferentes classes de terra nas unidades de mapeamento de solos. Foram avaliados o potencial geral de terras...

独立後のトルクメ二スタンの農業動向 OAK
平田, 昌弘; 石田, 紀郎; Hirata, Masahiro; Ishida, Norio.
中央アジアに位置するトルクメニスタンは、国土の大部分が年間降水量200mm以下であり、農耕地は国土面積のわずか3.3%にしか満たない。農耕地の98.6%は灌漑によっており、カラクム運河の水資源がトルクメニスタンにおける農業活動の生命線となっている。1996年から1998年にかけて、牧草類生産用の農耕地を穀物類栽培に大きく割り当てたこと、そして、穀物類と綿花の収量が向上したことにより、大規模農場による穀物類と綿花の栽培が増加した。一方、独立した個人農民への土地私有権の分配はいまだほとんど進展していない。しかし、トルクメニスタンにおける農作物生産量、農作物収量、家畜飼養頭羽数および畜産物生産量は増加傾向にあり、徐々にではあるが民営化の効果は現れ始めている。土地利用権としての農業用地の農民への還元、農民への優遇政策、基本資材の無料供給、国土面積の狭さからくる流通における利点などが、農民の生産活動に有利に働いた。農耕地拡大と農作物収量の向上とともに、トルクメニスタンにおける農作物生産はこれからも成長を続けるであろう。 The annual rainfall in most parts of Turkmenistan is less than 200 mm,and consequently,cultivated fields comprise only 3.3% of the total land area. The majority of the cultivation,98.6%,makes use of irrigation,and the water supply from the Karakum Canal serves as a vital resource for the cultivation...
