Isoda","doi":"10.11178/JDSA.11.31","DOIUrl":"https://doi.org/10.11178/JDSA.11.31","url":null,"abstract":"(ARENA), Type 2 diabetes mellitus (T2DM) is a serious health problem, and the number of affected persons is increasing annually worldwide. Obesity is the main cause of diabetes. As an individual gain weight, adipocytes are observed to become bigger. Hypotrophic adipocytes shows decreased adiponectin secretion and increased free fatty acids and inflammatory adipokines, which leads to lowered insulin sensitivity and metabolic activity. In contrast, having smaller and fewer adipocytes lead to increases in insulin sensitivity and adiponectin secretion and decreases in the release of inflammatory cytokines. Therefore, increasing the number of smaller adipocytes has been suggested as an effective strategy to prevent and treatment of T2DM. Although thiazolidinediones, such as troglitazone and pioglitazone, which are used currently to treat T2DM, can improve insulin sensitivity by increasing the number of small adipocytes, the side effects of these drugs include weight gain and liver failure. As an alternative treatment for T2DM, polyphenolic compounds, such as nobiletin and sakuranetin, reportedly induce preadipocytes to become small adipocytes. In addition, our recent study showed that the polyphenol cyanidin-3-glucoside (Cy3G), an anthocyanin, similarly induces 3T3-L1 preadipocytes to become small adipocytes, and several other researchers have obtained diverse evidence that supports the efficacy of Cy3G in the prevention or treatment of T2DM. Here, we summarize the activities of Cy3G that may support its use in the prevention of T2DM, focusing on the drug’s effect on adipocytes.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312481","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}

Ardales","doi":"10.11178/JDSA.6.114","DOIUrl":"https://doi.org/10.11178/JDSA.6.114","url":null,"abstract":"In a developing country like the Philippines, it is important to understand the challenges involved in feeding a rapidly increasing population and dealing with environmental concerns, and it is vital to include agriculture and environmental education in the basic curriculum. Agriculture, industrial arts, and entrepreneurship are included in the secondary curriculum of both public and private schools, as prescribed by the Philippine Department of Education, and topics related to the environment are required to be integrated into different subjects being taught in these schools. The University of the Philippines Rural High School (UPRHS), one of the basic education units of the University of the Philippines (UP), was originally established as a vocational agricultural school. Historical events as well as outstanding developments in the UP College of Agriculture (now UP Los Banos) led to the evolution of UPRHS from a vocational school to a science-oriented college preparatory high school. The school continues to offer agriculture as one of the major subjects for all grade levels. The students are encouraged to undertake research projects addressing agricultural and environmental issues. In support of its science and agriculture programs, the UPRHS maintains a strong connection with UP Los Banos and other nearby research institutions. The school also sends participants each year to the Asian Agricultural High School Student Exchange Program sponsored by Gunma Prefecture, Japan. The UPRHS aims to popularize its agriculture and environment-related programs through academic requirements, co-curricular activities, and community-based involvement.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128594394","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}

Low production levels and poor marketing can put these households at an economic disadvantage. This paper examines income levels, the contribution of different sources of income, and the extent of income diversification of rural households in two communities in the Mporokoso district of Northern Province, Zambia. In addition, the paper examines people's perception of their earnings and the possibilities for increasing them. For this purpose, data were collected in a survey of household demographic characteristics, monetary income by source, agricultural production, and perceptions of livelihood. In addition, direct interviews were conducted to identify perceived problems with income-generating activities. Using this information, three types of analyses were conducted: (1) a comparative analysis between the two communities to determine income sources and diversification; (2) an econometric analysis of income earnings as related to human capital, family workforce, land, and other household characteristics; and (3) a problem tree (cause-effect) analysis. The analyses indicate that, to sustain income growth in these and similar areas, cultivation of more beans and groundnuts should be promoted through improving soil fertility and expanding the area under cultivation. Livestock development would also contribute to enhanced household income through animal sales , enable expand cultivated area and manure provision to sustain crop production.","PeriodicalId":386623,"journal":{"name":"Journal of Developments in Sustainable Agriculture","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121040639","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}

And agriculture, rice growing or rice monopoly culture particularly, has been their major means of income and provision long since. Historical records confirmed that the northern Thai or the “Lanna Thai” people, who also live in the basin areas of many major rivers (ping – wang – yom nan) originating from the high mountains passing through, have learned and had experiences practicing “Muang Fai” irrigation system managemrnt for agriculture for longer than 700 years. This is before Phya Mangrai, king of “Lanna Thai” kingdom (B.E.1262-1317) founded its capital “Chiang Mai” and issued the irrigation law known as “Mangrai Sart” or “Winitchai Mangrai” 1 ) in the same year of B.E. 1839 (A.D.1296). There are also documents on ancient Lanna Thai and other records of Chiang Mai stating that the muang fai irrigation had long existed in Lanna Thai kingdom during B.E. 1100-1200 (A.D.557-657) or about 1,348-1,448 years before. Water user members of Muang Fai system help each other constructing weirs or diversion dams to block the waterway in the upper part and digging irrigation canal, known among the northerners as “lam -muang” to direct the water to lower plains, resulting in muang fai system community through the forming of an organization of administrators and managers in charge of systematic water usage for cultivation. The muang fai or weir system helps ease the administration and the developing of agricultural economy.

Ofrecio","doi":"10.11178/JDSA.1.1","DOIUrl":"https://doi.org/10.11178/JDSA.1.1","url":null,"abstract":"The National Irrigation Administration (NIA) is the government agency in the Philippines mandated to develop water resources for irrigation purposes. It is classified as a government-owned and controlled corporation. A major strategy implemented by NIA is the application of the so-called participatory approach program (PAP) concept in the irrigation environment. This approach enables all stakeholders to be involved in practically all phases of the irrigation endeavor. The concept was introduced in the early 1*s and with its positive results was institutionalized in all projects implemented by NIA. Before the introduction of PAP, the agency was doing all the planning, designing, construction and operation functions with almost no participation from the project beneficiaries -the farmers. Central to PAP is the organization of irrigation beneficiaries into formal groups called Irrigators Associations (IA). Through a professional NIA sta# member called an Institutional Development O$cer (IDO) deployed to the irrigation area, the IAs are trained in various aspects of basic leadership, financial management and irrigation system management to equip them with the capability to manage their associations. Eventually, the IAs are granted legal recognition by the government allowing them to enter into contracting arrangements in the management of the operation and maintenance (O&M) of the irrigation systems. The formal organization and legal recognition of the IAs have empowered the irrigation beneficiaries to become self-reliant and independent organizations. The contracting agreements, collectively called O&M contracting, are canal maintenance, irrigation service fee (ISF) collection and complete management take over of small irrigation systems. In the canal maintenance agreement (called Type +) an IA receives approximately Phillipine pesos +,.** (US $ ,0) per month while under ISF collection agreement (called Type ,), the IA gets a commission ranging from , to +/ of the collected amount. Under complete management takeover (Type -), the IA assumes complete management of the system and pays, through annual amortization, the construction or rehabilitation costs. An expanded version of the O&M management turnover program called Irrigation Management (IMT) was later introduced. IMT a#ords IA and NIA the option for a joint system management of canal systems or complete management takeover of relatively small systems. One salient feature of IMT is negotiation between the two parties regarding the sharing of the collected ISF and responsibilities for the repair and maintenance of facilities and structures. Contracting provides an opportunity for the IAs to generate funds that are in turn used to finance some projects and activities. Overall, participatory management has generated optimistic gains in the improvement of NIA and IA operations. But some refinements to the program still have to be instituted in order to upgrade these initial gains.
