{"title":"Structural Approach in the Participatory Muang Fai Irrigation Management","authors":"T. Ounvichit","doi":"10.11178/JDSA.3.40","DOIUrl":"https://doi.org/10.11178/JDSA.3.40","url":null,"abstract":"This paper analyzes the approach and principles that self-reliant farmers in a smalland a large-scale Muang Fai system in northern Thailand used in managing their irrigation systems. With keenness in water resources development, the farmers located their weirs where they could get abundant river flow and built their irrigation systems with an adequate capacity to supply water to all members on a continuous and simultaneous basis. These starting hydraulic conditions bailed them out of recurrent water conflicts that farmers with limited natural endowment and irrigation infrastructure faced. Hence, their attitude toward irrigation management was not geared towards conflict management. Rather, they were more oriented toward the structural approach in bringing about orderly irrigation management. Their participatory management process was composed mainly of a platform for exchanging information on physical conditions, water requirements and farming schedules, a forum for deciding a joint irrigation management plan, and a public commitment to honor the plan. The farmers who had agricultural productivity as their incentives and voluntarily identified themselves as Muang Fai members participated in the cross section of collective activities or functions, directly in the small-scale system, and through village sub-groups in the large-scale system. With close proximity, the small Muang Fai group used irrigation intake widths, which were relatively more precise, as the basis for water and cost distribution and kept straighter working rosters and financial accounts. With economy of scale, the large Muang Fai group used the more sloppy irrigation acreage as the basis for water and cost distribution and faced more risks of dysfunctions in their management process. However, the Muang Fai structural approach achieved an equilibrium because, in devising a harmonious irrigation management at the farm, village, and system levels, the horizontal as well as vertical social interactions between the members, their village irrigation delegates and their Muang Fai managers adhered to the principles that all members shall be equally treated, and all management activities shall be transparent and accountable to the members.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117108415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Water Value and Sustainable Use in the American SW","authors":"M. Grismer","doi":"10.11178/JDSA.2.1","DOIUrl":"https://doi.org/10.11178/JDSA.2.1","url":null,"abstract":"As elsewhere in the world, anticipated population growth in the next 50 years, climate change and reduced surface water availability, water “productivity”, or water use efficiency (WUE) must continue to improve in the American Southwest. Beyond the intrinsic value to life, water takes on additional value as food and fiber, fisheries and ecosystem benefits that are linked such that emphasis of one over the other benefit often results in losses neglected in the past. For example, development of upstream water storage exchanges downstream fisheries and ecosystems benefits for crop production, while reservoir evaporation losses further reduce possible downstream resource values. Unlike WUE improvements in the municipal sector, possible through metering and technological changes in flow devices and washing appliances, improved WUE in crop production is hampered by unidentified achievable water use targets. In terms of water use, the dominant crops in the Southwest are alfalfa and sudangrass hay and cotton lint production. The water use characteris tics, average planted areas and yields, and water values are examined for these crops in Arizona, California and Idaho to determine possible target WUEs and assess possible onfarm water savings in the region based on actual production information from 1988-2000. Field -based WUEs of 1.7, kg/ha-mm for alfalfa and sudangrass hay and pima cotton, and 2.1 kg/ha-mm for upland cotton lint production appear to be practical target values from which to determine appropriate water use. Based on FAO #56 estimated and yield-based water use for these three crops, possible water savings of up to 50% exist with the greatest water savings potential in desert regions where current water values as hay or lint crops are low relative to other regions. Such high water savings in the desert region are unlikely and targets of 20-30% corroborated by research trials, are more likely. The greatest water values and least possible water savings occur in the southern San Joaquin Valley, CA where the combination of relatively high ET and some rainfall occur. This research is a starting point for assessing water use/savings at the field scale for hay and cotton productions and should be extended to other crops. Additional work may also be required considering water savings at the district scale associated with the water distribution systems.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129613986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sarhadi, Samadi Ahmad Fahim, Kim Tangutan","doi":"10.11178/JDSA.9.41","DOIUrl":"https://doi.org/10.11178/JDSA.9.41","url":null,"abstract":"Nearly 80% of Afghanistan’s population lives in rural areas and depends heavily on livelihoods in the agriculture sector, which, in turn, depends on agricultural production. Agricultural education is essential for fulfilling basic human and animal needs, such as food, fodder, fiber, and energy, while ensuring long-term stewardship of natural resources and the environment. Agricultural development in Afghanistan depends on agricultural education at the national and international levels. Such education is implemented by agricultural specialists and expert farmers. Scientific and research-based education is applied through agricultural schools and institutions and their faculties, whereas traditional education is provided by expert farmers through their sustainable agricultural practices. Agricultural education can have an important effect on the sustainable development of the agriculture sector. The greatest challenges to agricultural education in Afghanistan are proper management, institutional policies and strategies, research activities, funding, and continuous war and security issues. Agricultural development also requires a focus on sustainable agriculture in the curriculum. Education and training are widely recognized as contributors to national economic growth. Although many organizations and institutions are providing agricultural education to specialists as well as farmers, the lack of updated materials is a substantial challenge in Afghanistan. The two main objectives of agricultural education in Afghanistan are: (1) to give updated information on agricultural progress from around the world to Afghan farmers, and (2) to provide essential training in agricultural technology, sustainable cultivation practices, post-harvest handling, irrigation, fertilizer management, biodiversity conservation, soil health, dealing with biotic and abiotic stresses, and climate change and its effect on agriculture production.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130225123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thailand is home to various Zingiber wild species. However, the biological activity evidence of these other species is less well studied than that of Z. officinale. In this study, we investigated the rhizomes of 10 Zingiber species to determine the correlations between total phenolic content, total curcuminoid content, and antioxidant activity, as determined by means of DPPH (2,2-Diphenyl-l-picrylhydrazyl) and ABTS (2,2′-azinobis-(3-ethylbenzothiazoline-6sulfonic acid) diammonium salt) assays. We also used high-performance liquid chromatography and gas chromatography to determine the quantities of 6-gingerol and terpinen-4-ol, respectively which are the two most important active compounds associated with antioxidant and anti-inflammatory action. Antioxidant activity was highly correlated with total phenolic content. To the best of our knowledge, this is the first report of the antioxidant activities of three of the species (Z. rubens, Z. bisectum, and Z. barbatum). The rhizome extracts of Z. montanum showed the highest total curcuminoid content and yielded the highest amount of essential oil and terpinen-4-ol content. 6-Gingerol was detected in only two species: Z. officinale and Z. cornubracteatum. Our results suggest that Z. montanum may be an excellent natural remedy owing to its considerable antioxidant activity and the large amounts of known bioactive chemical constituents it contains. It may be a source of additional bioactive compounds.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128867173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main competencies required of graduates of the master of science program are: (a) capability to manage watersheds through problem identification and quantification of land management issues in watershed areas (Le., Hoods, droughts, erosion and sedimentation, reduction of land productivity), (b) capability to identify and measure the effect of watershed management strategies and techniques designed to overcome problems stemming from the misuse of land resources, and (c) capability to design sustainable watershed managment plans. For doctorate programs, the target competency is the ability to identify and answer gaps in scientific knowledge so as to improve the planning and application of strategic watershed management for maintaining sustainable watershed resources. Integrated watershed management and sustainable agriculture are explicitly described in the curriculum of SPWM through subjects that include: soil and water conservation; analysis of hydrological systems; land use planning; sustainable agricultural systems; water resource planning; watershed management; and watershed management technology, strategy, and policy. The majority of research efforts have been directed at maintaining and increasing watershed functions to support the dynamics of life, incorporating ecological, economic, and social dimensions. Projects have been designed to: (a) select soil and water conservation technologies (site specific), (b) explore several indigenous integrated conservation farming systems, (c) study land use change, (d) design watershed management plans, (e) minimize Hooding (magnitude and frequency), (f) increase water availability (spatially and temporally), (g) estimate the effects of Hoods and Hood mitigation, (h) increase and develop institutional roles in watershed management, and (i) develop and apply hydrological and erosion models. Sustainability indicators examined in these research programs have included enhanced farmer outcomes (economic viability), increased adoption of technology by farmers using locally available resources (technologically appropriate), and no significant degradation of natural resources (ecologically friendly).","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"31 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120907082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No-tillage is an agricultural practice whereby a crop is established without any prior tillage or burning of the land. and it was introduced to Ghanaian farmers by the Ministry of Food and Agriculture in 1995. In this study, factors affecting the promotion, adoption, and impacts of no-tillage farming were assessed. Questionnaires were administered to 50 farmers categorized as: adopter (practicing no-tillage farming), deserter (abandoned the practice), or never (never practiced no­ tillage). Slash-and-burn farmers used 16 man-days/ha for land preparation, whereas no-tillage farmers required 14 man-days/ha for land preparation. In-crop weed control required 12 man-days for slash-and-burn farming and 8 man-days under no-tillage. Slash-and-burn farmers employed 18 man-days/ha for harvesting maize, whereas no-tillage farmers used 24 man-days/ha. No-tillage farmers listed the following benelHs of using this system: increased yield (18% of respondents), reduced labor (17%), conserved soil moisture (16%), improved soil nutrients (15%), increased farm size (13%), reduced soil erosion (11 %), and reduced production costs (10%). Information on no-tillage practices was diffused by farmer-to-farmer information transfer. Most farmers practiced a mixed cropping system instead of a crop rotation system, and male farmers were seen to be more innovative and likely to adopt new technologies than their female counterparts. The reported challenges associated with no-tillage included poor society recognition of no-tillage practices, difficulties in planting through residues and application of herbicide, and pest invasion. The lack of no-tillage planters makes it rather difficult for large-scale farmers to switch from conventional farming to no-tillage. More effort is needed to investigate multipurpose conservation farming approaches suitable for fruit and crop production. Agricultural engineers and other experts must collaborate to develop suitable conservation agricultural tools and equipment for small-scale farmers to enhance agriculture production.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125065036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
