<p>Following the release of Presidential Regulation No 1/2016, a peat restoration pilot project has been carried out in Banjarbaru District, South Kalimantan in addition to other two pilot projects in other provinces of Indonesia. The pilot project has been designed to implement the three aspects of peat restoration, namely rewetting, revegetation and revitalization of society.  Implementation of revegetation is mainly through applying agroforestry by growing agricultural crops in spaces between trees. The objective of present study was to elucidate the suitability of agricultural crops in area of restoration of degraded peatland in South Kalimantan, Indonesia. The suitability of agricultural crops was studied by collecting rainfall and air temperature data from the climatic station of Syamsudin Noor Airport in Banjarbaru, while the nutrient retentions values were determined in the laboratory. Peat depth and drainage class were determined by direct field observations, while peat decomposition level was classified by quantitative method in the field. All collected data were then used to assess the land suitability class for  dry land paddy (<em><span style="text-decoration: underline;">Oriza</span> <span style="text-decoration: underline;">sativa</span></em> L), long bean (<em><span style="text-decoration: underline;">Vigna</span> <span style="text-decoration: underline;">sinensis</span></em> ENDL), cucumber (<em><span style="text-decoration: underline;">Cucumis</span> <span style="text-decoration: underline;">sativus</span></em> LINN), mustard (<em><span style="text-decoration: underline;">Brassica</span> <span style="text-decoration: underline;">rugose</span></em> FRAIN), orange (<em><span style="text-decoration: underline;">Citrus</span></em> sp), <em>stink bean</em> (<em><span style="text-decoration: underline;">Parkia</span> <span style="text-decoration: underline;">speciose</span></em> HASSK), rubber (<em><span style="text-decoration: underline;">Hevea</span> <span style="text-decoration: underline;">brassialiansis</span></em> M.A), and coconut (<em><span style="text-decoration: underline;">Cocus</span> <span style="text-decoration: underline;">nocifera</span></em> L). The productivity data of long bean, cucumber and mustard were obtained by farmer interview. The results showed that most of the agricultural crops were classified as marginally suitable (Class S3).The main limiting factors of agricultural development in this area are low soil pH, low base saturation and peat ripening. Peat depth limits the development of some crops. The above mentioned limiting factors ought to contribute to the low crop productivities in the area. The limiting factors were less severe for pineapple and stink bean, indicating that these crops have potential to be grown along with trees for restoration efforts in the area.</p>

<p>Volcanic soil is soil developed from pyroclastic materials released during the volcanic eruption. Althought the soil is fertile, it is mostly occurred in steep sloping highland that is critical to landslide and volcanic eruption. This paper discussed the characteristics and distribution of volcanic soils in sloping dry land, completed with the potential and constraints of their use for agricultural development. This information supports the zonation program of agricultural commodities in Indonesia. Volcanic soils distributed on the islands of Sumatra, Java, Bali, Nusa Tenggara, North Sulawesi and North Maluku. Mostly characterized by black or brownish A horizon and yellowish B horizon, crumb soil structure, crumbly consistency, high organic matter content, and low bulk density. The primary mineral composed by hyperstein, amphibole, augite, andesine, volcanic glass, plagioclase, labradorite, olivine, sanidin, apatite and biotite. The secondary minerals are d allophane, imogolit, ferrihydrite, halloysite, kaolinite and gibsite. Soil reaction vary from very acid to neutral with medium nitrogen content (on average). The potential P is low except in volcanic soils in Java. The P retention is high. The Cation exchange capacity varies from moderate to very high. The morphological, chemical and physical properties are good for supporting plant growth, except for those with high P retention. The land suitability classes are very suitable (S1) to marginally suitable (S3) for highland horticultural crops (vegetables and fruits) and estate crop plantations (tea, arabica coffee, and quinine). The limiting factors are relief/slope/erosion hazard and low soil fertility. These limiting factors can be eliminated by applying good agricultural and conservation practices that balance between land sustainability and productivity aspects.</p><p>Keywords: Volcanic soils, pyroclastic, characteristics, potential </p><p> </p><p><strong>Abstrak</strong></p><p>Tanah vulkanik terbentuk dari bahan piroklastika hasil erupsi gunung berapi dan sebagian besar berada di dataran tinggi lahan kering berlereng sehingga rawan longsor.

The Impact

Purpose Canada’s primary care system has been described as “a culture of pilot projects” with little evidence of converting successful initiatives into funded, permanent programs or sharing project outcomes and insights across jurisdictions. Health services pilot projects are advocated as an effective strategy for identifying promising models of care and building integrated care partnerships in local settings. In the qualitative study reported here, the purpose of this paper is to investigate the strengths and challenges of this approach. Design/methodology/approach Semi-structured interviews were conducted with 34 primary care physicians who discussed their experiences as pilot project leads. Following thematic analysis methods, broad system issues were captured as well as individual project information. Findings While participants often portrayed themselves as advocates for vulnerable patients, mobilizing healthcare organizations and providers to support new models of care was discussed as challenging. Competition between local healthcare providers and initiatives could impact pilot project success. Participants also reported tensions between their clinical, project management and research roles with additional time demands and skill requirements interfering with the work of implementing and evaluating service innovations. Originality/value Study findings highlight the complexity of pilot project implementation, which encompasses physician commitment to addressing care for vulnerable populations through to the need for additional skill set requirements and the impact of local project environments. The current pilot project approach could be strengthened by including more multidisciplinary collaboration and providing infrastructure supports to enhance the design, implementation and evaluation of health services improvement initiatives.

 This study presents financial evaluation of 18 kW solar photovoltaic powered Baidi Micro Grid implemented by Alternative Energy Promotion Center (AEPC) in Dubung village, Rising Gaupalika, Tanahun district of Nepal. The grid is built and is operational under Baidi Micro Grid Pvt. Ltd, a Special Purpose Vehicle (SPV) established under “Pro-Poor Public Private Partnership (5P)” concept supported by United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP) & International Fund for Agricultural Development (IFAD). It is pilot project under 5P concept in Nepal. People from Dubung and Mauribas village as well as Saral Urja Nepal Pvt Ltd (SUN) jointly owns the SPV strengthening not only technical, managerial and financial support but also the community participation and engagement in all decision making process. The total cost of the project is NPR 13,395,000.00 at 2015 AD. The grant for the project was of value NPR 11,295,000.00 from AEPC, IFAD and UNESCAP and remaining was equity of SUN. The net present value of NPR -10,978,605.76 is obtained at 3% discount rate due to unavoidable replacement cost of batteries, charge controllers, inverters and high initial investment without the consideration of the grant amount. Whereas, with 84.32% utilization of available grant, the NPV worth of NPR 384,394.22 is obtained for the project. In breakeven analysis, a breakeven point of the project is obtained at 81.87% utilization of the grant. Without grant, project like Baidi Micro Grid will not sustain. In addition, average unit cost of electricity is found to be NPR 37.08 but it varied from NPR 16.67 to NPR 80.81. Household consuming more electricity has to pay less unit cost of electricity whereas household consuming less electricity had to pay higher unit cost of electricity.

Payback Framework

Abstract Introduction: The Clinical and Translational Science Awards (CTSA) program of the National Center for Advancing Translational Sciences (NCATS) seeks to improve population health by accelerating the translation of scientific discoveries in the laboratory and clinic into practices for the community. CTSAs achieve this goal, in part, through their pilot project programs that fund promising early career investigators and innovative early-stage research projects across the translational research spectrum. However, there have been few reports on individual pilot projects and their impacts on the investigators who receive them and no studies on the long-term impact and outcomes of pilot projects. Methods: The Georgia CTSA funded 183 pilot projects from 2007 to 2015. We used a structured evaluation framework, the payback framework, to document the outcomes of 16 purposefully-selected pilot projects supported by the Georgia CTSA. We used a case study approach including bibliometric analyses of publications associated with the selected projects, document review, and investigator interviews. Results: These pilot projects had positive impact based on outcomes in five “payback categories”: (1) knowledge; (2) research targeting, capacity building, and absorption; (3) policy and product development; (4) health benefits; and (5) broader economic benefits. Conclusions: Results could inform our understanding of the diversity and breadth of outcomes resulting from Georgia CTSA-supported research and provide a framework for evaluating long-term pilot project outcomes across CTSAs.
