‘Wet’ Water Saving and Social Benefits from Micro Irrigation: A Study from IGNP Command Area in Rajasthan

Desertification has caused great harms to the ecological environment and socio-economic. Through many years test in Xinjiang desert area, some useful modes of desert governance can be implemented: (1) making use of advanced water-saving irrigation technology; (2) combining reasonable cropping patterns with higher economic value plants like arbors, shrubs and medicinal herbs planted in the desert, which not only plays the roles of windbreak and sand fixing, but also can gain some economic, ecological and social benefits.

Abstract. A great number of agricultural sheds are used in the China's farmland. With the development of science and technology and water use of tension , nowadays various proposed micro-irrigation techniques for the agricultural shed irrigation have been put forward , but as high-tech product and extremely high cost, the farmers cannot afford it, thus they have no choice but to use the traditional slow methods. To seek for the low cost of water-saving irrigation way, this paper put forward the original canopy stents arch tube after drilling converted into a canopy of the support and the unity of the new irrigation micro-irrigation technique, which has been combined with the new type of irrigation trellis to make complete design planning.

Conveyance Losses

The comparative conveyance losses between lined and unlined canals, impact of water saving on command area development and irrigation cost, and farmers acceptability of lined canal in shallow tubewell (STW) irrigation schemes were studied during 2010-11 Boro season at three upazilas: Manikgonj Sadar of Manikgonj district, Dhamrai of Dhaka district and Mithapukur of Rangpur district. The conveyance loss was measured using inflow-outflow method and focus group discussion (FGD) was carried out with the pump owners and farmers to assess the impact of water saving on command area development and the acceptability of lined canal technology. Average conveyance losses were found to be 41, 48 and 45% in the existing earthen canals; 18, 21 and 24% in improved earthen canals; and 12, 11 and 13% in pre-cast canals at Mithapukur (M1), Manikgonj Sadar (M2) and Dhamrai (D) schemes, respectively. The water saving did not increase the command area in any of the schemes but reduced the irrigation time and saved fuel requirement for irrigation. On an average, 32, 23 and 30% fuel were saved by improved earthen canals where as 45, 46 and 48% were saved by pre-cast canals for M1, M2 and D schemes compared to earthen canal. The benefit-cost ratios of improved earthen canals were 1.36, 1.38 and 1.30 where as 3.36, 4.28 and 3.34 by pre-cast canals for M1, M2 and D schemes, respectively. The internal rate of return (IRR) from the investment on water distribution was over 50%. The lining technology was acceptable to pump owners, but did not impress the farmers who share the crop with the pump owners as price of irrigation or pay on the basis of irrigated area. In order to make the technology acceptable to the farmers, polices must be framed to share the benefits of lining by the pump owners with the farmers by reducing the price of irrigation water or through financial support of GO and NGOs for efficient use of STW irrigation system in Bangladesh.The Agriculturists 2014; 12(2) 116-125

Micro Irrigation

Scarce water resources limit protected vegetable production in North China. Implementing efficient water-saving techniques is crucial for maintaining protected vegetable production and sustainability. A two-growing season field experiment was conducted in a glass greenhouse to explore the effects of water-saving techniques with irrigation scheduling based on soil water content on the growth and quality of pakchoi and the fate of irrigation water. Three water-saving techniques were investigated: micro-irrigation (M-0), furrow irrigation with plastic mulch (F-P), and micro-irrigation with plastic mulch (M-P) compared to furrow irrigation (F-0). F-P and M-P treatments enhanced pakchoi growth and primarily increased the total root length of the root system (0–0.2 m) compared to F-0. The two treatments further induced an improvement of pakchoi quality. Compared to M-0, F-P and M-P treatments showed better performance in reducing evaporation by 57–70% and proportion of evaporation in evapotranspiration, and consequently exhibited more pronounced effects on water saving. Irrigation water use efficiency (IWUE) was improved in F-P by 50% in both seasons and was improved in M-P by 84 and 95% in spring season and autumn season, respectively. Combining irrigation scheduling based on soil water content with plastic mulch is a feasible way to improve IWUE in protected vegetable production by reducing water consumption and enhancing crop growth.
