{"title":"Decision Support Tools for Water Resource Management:A Case Study of Bung Boraphet Wetland, Thailand","authors":"N. Sriwongsitanon, Kritsanat Surakit, P. Hawkins, N.

Sustainable management and ‘wise-use’ of the Wetland’s resources require achieving a balance between economic exploitation and conservation. Scientifically based decision support tools are vital to gain better insights into the complex interactions between the large wetland system, its contributing catchment and floodplain, and then pave the way for planning effective long-term management. This paper presents a summary of several decision support tools that we developed for Bung Boraphet. The tools are: (a) Water budget predictive model, (b) Land-use analysis using satellite imagery, and (c) Database linked Geographic Information System. From a review of literature and field studies, we identified the factors, which are having the most serious impacts on long-term sustainability of Bung Boraphet. We also conducted field studies to collect primary data on hydrological parameters on the lake between December 2002 and May 2006. These, and available secondary data, were then used to develop a model for the daily water budget of the Wetland. Model calculations and observed water levels are highly correlated for this period, proving the veracity of the model. Evaporation loss of water is a critical factor during the dry seasons (~ 41% loss), as is extraction for irrigated rice grown in encroached areas around the lake (~55% loss). The modeling tool allows the analysis of different water use scenarios. For instance, the model forecasts that even if the weir height is raised by 0.5 m to the level of +24.5 m (MSL), as has been suggested by some stakeholders, irrigation water abstraction has to be reduced by 35 % of the current consumption, to maintain the recommended minimum water level (+23 m, MSL) for sustainable fishery. Insights into land use change in the surrounding catchment and lake were gained by a series of Landsat 5 satellite imagery. A comparison of imagery shows that between 1993 and 2003, the irrigated area surrounding the lake doubled. At the same time, the submerged and emergent vegetation in the lake declined by 50%. The database linked GIS, which was developed, includes meteorological data and primary and/or secondary data on hydrology, water quality, and biodiversity of the lake and its catchments, and covers the main rivers and their tributaries. Information from applying the decision support tools has stimulated discussions with key stakeholders, identifying the ‘wetland values’, which need protection, and the economic, environmental, and social goals that need to be met by a future Plan of Management. As discussed in this paper, we have made a significant difference to the nature of the discourse in progress regarding managing Bung Boraphet by demonstrating the value of basing wetland management decisions on scientific grounds.

Nakasathien","doi":"10.11178/JDSA.10.115","DOIUrl":"https://doi.org/10.11178/JDSA.10.115","url":null,"abstract":"Grain barley (Hordeum vulgare L.) is the predominant raw material used to produce malt for industries such as brewing and the food industry. In Thailand, barley has been introduced to Thai farmers to improve farm income and reduce barley imports, but the seed quality of Thai-grown barley is often lower than required for profitable malt production, especially in the aspect of seed germination and vigor, and high pathogen contamination. Thus, this study was conducted to evaluate the effects of different seed priming methods on seed quality of Thai barley for malt production. Three experiments were conducted. The first experiment was hydro-priming: seeds were primed in deionized water for 6, 8, 10, 12, 14, or 16 hours. The second experiment was hydro-priming plus potassium nitrate treatment: seeds were primed in four different concentrations of KNO3 solution: 2.5, 5, 10, or 20 mg/ml for 6, 8, 10, and 12 hours. The third experiment was osmo-priming by PEG4000: seeds were primed in solutions of three different osmotic potentials: −0.50, −0.75, or −1.50 MPa for 10, 12, 14, or 16 hours. All seed priming methods accelerated barley germination and increased seed vigor. Primed barley seed germinated within 1 day. Barley seeds were primed with hydro-priming plus KNO3 at 5 mg/ml for 12 hours had significantly high seed germination and speed of germination. Hydro-priming plus KNO3 and osmo-priming by PEG4000 could speed up seed germination. We conclude that all three of these seed priming techniques could be effectively applied to improve barley seed quality in the Thai malt industry. However, further study is needed to evaluate the effects of seed priming methods on barley seed storability and other attributes of malt quality.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"253 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":"134070641","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}

In Ghana, land degradation has resulted in serious environmental problems with devastating socio-economic impacts on rural populations. Traditional methods of farming, including slash-and-burn land preparation and repeated mono-cropping on the same field, have led to a loss of organic matter in the soil and contributed to reductions in crop yield. Conservation agriculture (CA) aims to achieve sustainable and profitable agriculture and improved livelihoods of farmers through the application of three key principles: minimal soil disturbance, permanent soil cover, and crop rotation. This evaluation of factors affecting the promotion, adoption, and impacts of no-tillage agriculture revealed the need for agricultural extension agents (AEAs) to be trained in multipurpose conservation farming approaches for sustainable crop production. Currently in Ghana, there is a gap between the development and the delivery, adoption, and maintenance of agricultural technologies, and AEAs have been blamed for failing to transfer technologies developed by agricultural research institutes. Farmers and AEAs need to receive adequate training and education in CA technologies. To meet this objective, a CA manual for extension agents was developed in collaboration with Mr. Kofi Boa (a CA consultant) and AEA training sessions were conducted. A CA training and demonstration site was also created with the support of the Farm Front Services (CA service providers) to provide hands-on training in CA practices in Atwima Nwabiagya District in Ghana.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"20 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":"132430424","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}

Chinnasri, Sanchai Kwankuae","doi":"10.11178/JDSA.8.110","DOIUrl":"https://doi.org/10.11178/JDSA.8.110","url":null,"abstract":"In Sakhon, and Ratchaburi provinces, which are in the central region of the country, are the largest areas for guava cultivation. Kimju and Pansithong are the most extensively grown cultivars, and they have been seriously damaged by two species of root-knot nematodes, Meloidogyne incognita and M. enterolobii (or M. mayaguensis ). The latter species was only recently reported in Thailand but is common in China, Brazil, and the United States. Substantial numbers of guava trees are in decline and show reduced fruit production. In this survey study of six guava orchards in central Thailand, we found that common aboveground symptoms of nematode infection included yellowing, stunting, folded leaves, blighted and wilted leaves (especially when water was lacking), and slow ripening of fruits. Underground symptoms included root galls, partially rotted roots, and, in some cases, prolific production of adventitious roots to compensate for damaged and nonfunctional roots. When we examined the morphometric characteristics of second-stage juveniles of M. incognita and M. enterolobii obtained from soil around guava plants, we observed no significant correlation between the characteristics of the two species or between the characteristics of populations within each species ( P ＞ 0.05). For the biological control of root-knot nematodes in guava, we evaluated a commercially available fungal agent, Trichoderma harzianum , which effectively controls several other soil-borne pathogens and has been shown to induce disease resistance and stimulate adventitious root growth in plants. We found that inoculation of the root zones of guava plants with T. harzianum reduced the number of nematodes in both soil and roots as compared to the number in untreated plants ( P ＜ 0.05). Moreover, inoculation of guava plants with T. harzianum arrested the development of the juvenile nematodes ( P ＜ 0.05). Trichoderma harzianum is less expensive than chemical control agents and poses no risk to the environment.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"29 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":"123928741","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}
