Perceptions of Irrigation Water Management Practices in the Mississippi Delta

The Mississippi River Valley Alluvial Aquifer (MRVAA) is being depleted, and practices that improve water stewardship have been developed to reduce drawdown. This study assesses how Mississippi Delta producers changed their perceptions of these practices over time. The analysis employs data from two surveys carried-out in 2012 and 2014 of all Mississippi permittees who held an agricultural well permit drawing from the MRVAA. Focusing on water-saving practices, this study found that producer perception of the usability of flowmeters improved over time. About 80% and 90% more producers growing corn and soybeans, respectively, felt that computerized hole selection was highly efficient. In 2014, 38% of corn and 35% of soybean producers believed that shortened furrow length was a highly efficient practice—up from 21% in corn and 24% in soybean producers in 2012. Approval of irrigation automation, moisture probes, and other irrigation technology rose from 75%of producers in 2012 to 88% by 2014. Favorability toward water-saving practices increased overall between the survey years.

Barrier knock-down weir as an alternative technology for irrigation

Sand bags are one of the technologies still widely used to elevate water level. The sand bags are arranged in order to dam the river flow and to irrigate agricultural land, especially during the dry season. In line with its utilization, water supply of this technology is still less effective, thus, alternative technology is needed. This study aimed to test Barrier Knock-Down as an alternative technology that can be assembled and stored. This study was a quantitative research conducted by testing the prototypes. The tests were carried out using a monitor instrument Diver, piezometer. The tests of comparison were conducted in 4 types: Type 1, it was an L shape filled with sand+water; Type 2 was I shape filled with sand+water; Type 3 was an I shape filled with water; Type 4 was in an L shape filled with water. From the results of the study, type 1 is the best method for weir irrigation technology because of its ability to resist vertical and horizontal force than other types. Type 1-an L shape filled with sand+water with the value of safety factor rolling stability 5,28 and shear stability 2,23. Experiment result a stable elevation value in weir, did not experience a shift.

Sufi Modernis: Peran Transformatif Mursyid TQN Suryalaya dalam bidang Pendidikan, Ekonomi dan Lingkungan Hidup

<p class="06IsiAbstrak">This study aims to reveal that the Tarekat in organizational review will develop rapidly if it is led by a Mursyid who has a transformative modernist role. This qualitative research was conducted using a phenomenological approach, participant observation approach and descriptive analysis. The results of the study reveal that TQN Suryalaya has modernist Sufi figures, namely the first Mursyid of TQN Suryalaya Abah Sepuh (Shaykh Abdullah Mubarok Bin Nur Muhammad) then followed by the second Murshid Abah Anom (Shaykh Ahmad Shohibul Wafa Tajul 'Airifn). Through these two Mursyids, it was found that the form of modernization typical of Sufis apart from in the field of ritual worship which is of course the main key, but furthermore has a role in transforming the quality of society towards a better direction in three fields: First, the field of education in the form of formal institutions in the field of basic education, secondary, and college. Second, in the field of Economics in the form of collaboration between Islamic boarding schools and SMEs in the surrounding community. The third is in the field of the environment in the form of nature conservation, irrigation technology, and plantations.</p>

Center Pivot Irrigation Systems and Where to Find Them: A Deep Learning Approach to Provide Inputs to Hydrologic and Economic Models

Availability and quality of administrative data on irrigation technology varies greatly across jurisdictions. Technology choice, however, will influence the parameters of coupled human-hydrological systems. Equally, changing parameters in the coupled system may drive technology adoption. Here we develop and demonstrate a deep learning approach to locate a particularly important irrigation technology—center pivot irrigation systems—throughout the Ogallala Aquifer. The model does not rely on super computers and thus provides a model for an accessible baseline to train and deploy on other geographies. We further demonstrate that accounting for the technology can improve the insights in both economic and hydrological models.

Peer Irrigators and the Choice of Field Management and Water Control Practices for Irrigation in Arkansas

We examined how irrigation techniques in use by family and friends influence the use and share of land utilizing different irrigation techniques by Arkansas producers. A bivariate sample selection model simultaneously estimated how farm characteristics determine the use and explain the share of a farm that utilizes an irrigation technique. We found that the irrigation techniques in use by family and friends do affect the irrigation techniques a producer uses and the share of acres utilizing different irrigation techniques. A producer with a family or friend that uses end-blocking irrigation is 41% more likely to use end-blocking themselves. Having a family or friend who uses pivot irrigation technology tends to decrease the share of irrigated acres that utilizes end block irrigation by 0.211. We also found that when the irrigation techniques in use by family and friends interact with variables such as location and participation in a regional conservation partnership program, the effects on the producer’s decision vary. The share of irrigated acres that use cutback irrigation decreases by 0.21 for a producer who has a peer that uses irrigation scheduling. However, if the producer lives along Crowley’s Ridge and has a peer that uses irrigation scheduling, the share of irrigated acres that use cutback irrigation decreases by an additional 0.54.

Policy, Technology, and Management Options for Water Conservation in the Ogallala Aquifer in Kansas, USA

The Ogallala Aquifer underlies 45 million ha, providing water for approximately 1.9 million people and supporting the robust agriculture economy of the US Great Plains region. The Ogallala Aquifer has experienced severe depletion, particularly in the Southern Plains states. This paper presents policy innovations that promote adoption of irrigation technology, and management innovations. Innovation in Kansas water policy has had the dual effects of increasing the authority of the state to regulate water while also providing more flexibility and increasing local input to water management and regulation. Technology innovations have focused on improved timing and placement of water. Management innovations include soil water monitoring, irrigation scheduling, soil health management and drought-tolerant varieties, crops, and cropping systems. The most noted success has been in the collective action which implemented a Local Enhanced Management Area (LEMA), which demonstrated that reduced water pumping resulted in low to no groundwater depletion while maintaining net income. Even more encouraging is the fact that irrigators who have participated in the LEMA or other conservation programs have conserved even more water than their goals. Innovative policy along with creative local–state–federal and private–public partnerships are advancing irrigation technology and management. Flexibility through multi-year allocations, banking of water not used in a given year, and shifting water across multiple water rights or uses on a farm are promising avenues to engage irrigators toward more sustainable irrigation in the Ogallala region.
