Strategi Pemberdayaan Ekonomi Petani Garam Melalui Pendayagunaan Aset Tanah Pegaraman
No full textMadura bernilai strategis dalam produksi garam nasional, namun kenyataannya kondisi petani garam masih hidup di bawah garis kemiskinan. Penelitian bertujuan merumuskan strategi pemberdayaan petani garam melalui pendayagunaan aset pertanahan dengan pendekatan subsistem budaya-kelembagaan dan subsistem ekonomi. Guna mencapai hal tersebut, perlu diketahui kondisi subsistem budaya-kelembagaan dan subsistem ekonomi petani garam. Selain itu, dikaji faktor-faktor penyebab ketidakberdayaan petani. Hasil analisis menunjukkan subsistem budaya menunjukkan bahwa usaha pegaraman adalah bagian budaya masyarakat yang mengakar dan tidak dapat dipisahkan dari masyarakat Madura. Sementara dari subsistem kelembagaan menunjukkan petani garam dikelompokkan menjadi petani pemilik tanah dan petani penggarap (mantong). Pendekatan subsistem ekonomi menunjukkan bahwa produksi garam sangat tergantung iklim dan cuaca dan masih menggunakan teknologi tradisional. Strategi pemberdayaan bagi petani pemilik tanah adalah dengan mengupayakan sertifikasi tanah untuk mendukung akses permodalan. Sementara untuk mantong diarahkan memperoleh redistribusi tanah oyek landreform yang kemudian disertifikasi. Tanah tanah yang telah disertifikasi tersebut nantinya dapat dilakukan konsolidasi tanah yang berperan pada peningkatan kuantitas dan kualitas produksi garam serta mereduksi biaya transportasi. Tanah yang telah tersertifikasi juga dapat digunakan untuk agunan guna mengakses modal.
Madura has an important role in the national salt production. unfortunately, most of salt farmers in Madura are living under the poverty line. This paper discuss about the strategies to empower salt farmers through improving the access of lands, proposing culture-institutional and economic subsytem approch. This strategy can be formulated by investigate the condition of the cultural- institutional and economic subsystem of salt farmers. In addition, also discussed the factors that cause the incapacities of the farmers to improve their welfare. The result based on cultural subsystem show that salt production is part of the Madura culture that deeply entrenched. Then, based on institutional subsystem show salt farmers can be divided into two type: the farmers that own their lands and peasant farmers (mantong). Meanwhile, based on economic sub system describe the existing salt production system is traditionally managed, highly dependent on the weather and climate condition. An empowerment strategy for the landowners is to get land registration to access the capital. While empowering for mantong directed to acquire redistribution on land reform object. Salt land that has been certified can be consolidated which contribute to increasing the quantity and quality of salt production and reduce transportation costs. Then salt that has been certified can be be used for collateral in order to access capital.</jats:p
Wind energy acceptance: Linking perceived impacts and characteristics in Dutch wind energy projects
No full textThe number of wind energy projects in Europe has increased rapidly in the last decade and this growth is expected to continue. In the Netherlands there is a similar increase in the amount of wind energy projects. Wind energy projects, as large-scale infrastructural works and building projects, have numerous effects on the surrounding communities. The most prominent challenge in onshore wind energy realisation in the Netherlands was identified as a lack of acceptance by the local community and the potential for this lack of acceptance to result in resistance. This research focusses on acceptance of wind energy on a local level. However, acceptance can be a complex issue. There are multiple actors, technical characteristics, economic factors and institutional boundaries involved. To analyse this complexity, this research explores which impacts are perceived by local residents of a wind park; impacts as noise nuisance and shadow flicker. Literature suggests links between perceived impacts and the local context of a wind energy project. Local factors, like the height of the turbines, could influence local residents experience on for example noise nuisance. This research extends on these possible relations and aims to research how characteristics of a wind project and perceived impacts of local residents could relate. A case study of 18 Dutch wind energy projects was executed. For each project one or two interviews with a stakeholder were conducted on the perceived impacts of local residents. The data was combined with desk research on the characteristics of the wind parks. For each case study was further analysed how project characteristics and perceived impacts of residents could relate. Multiple possible relations were identified between characteristics and perceived impacts. Examples of these are turbine characteristics as distance to residents, height of turbines, the presence of other wind parks nearby and obstruction lighting. Additionally, regional characteristics as accumulation of existing regional impacts, regional property prices, regional stress and the if the wind park is located in a silent area were indicated as influential in some case studies. Institutional factors have been attributed to influence the process. These included the administrative division, decision making power and legal guidelines. Furthermore, measures to reduce or compensate impacts were also named as influential. These include the extent of financial participation and a standstill provision. Two general characteristics influencing wind energy acceptance in general were identified. These were if the wind park was located on an industrial site and if the wind park was a repowering project. In some cases, the characteristics could relate to other characteristics or perceived impacts relate to other perceived impacts. For example, interviewees stated the concerns for housing value decrease were directly related to concerns for shadow flicker, noise nuisance and visual impact. Even on a case level, multiple relations were mentioned and could have both negative as positive effects. On a broader level, a cross-case examination was done to discover the importance of the perceived impacts and what possible relations were frequent in Dutch wind energy project. While the exploratory research has its limitations, it discovered that acceptance is complex and depended on multiple factors. Relations as for example height turbines resulting in more visual impact that were mentioned in literature did not occur in every project. Some relations can be negative or positive depending on the project context. Furthermore, perceived impacts could be related to other perceived impacts and multiple characteristic might influence one perceived impact. This creates a complex web of interrelations where some relations appeared in the case studies but others are still unknown. This research show that further research is needed generate profitable knowledge on this complex topic. With the results of the thesis, a number of limited recommendations are done for local residents, policy makers and project executors. One of these recommendations is to implement a local approach to a case project and take the unique characteristics of the project into account. This includes integrating existing regional impacts to estimate which impacts could cause the most concerns. Additionally, consulting with local residents is an important step to fathom local wishes and preferences. Local residents might be willing to trade in time for extra benefits or need a technical implementation as a standstill provision. More insight in the perceived impacts of local residents can help in providing participation measures or structure the process.Industrial Ecolog
A highly conductive fibre network enables centimetre-scale electron transport in multicellular cable bacteria
No full textBiological electron transport is classically thought to occur over nanometre distances, yet recent studies suggest that electrical currents can run along centimetre-long cable bacteria. The phenomenon remains elusive, however, as currents have not been directly measured, nor have the conductive structures been identified. Here we demonstrate that cable bacteria conduct electrons over centimetre distances via highly conductive fibres embedded in the cell envelope. Direct electrode measurements reveal nanoampere currents in intact filaments up to 10.1 mm long (>2000 adjacent cells). A network of parallel periplasmic fibres displays a high conductivity (up to 79 S cm-1), explaining currents measured through intact filaments. Conductance rapidly declines upon exposure to air, but remains stable under vacuum, demonstrating that charge transfer is electronic rather than ionic. Our finding of a biological structure that efficiently guides electrical currents over long distances greatly expands the paradigm of biological charge transport and could enable new bio-electronic applications.BT/Environmental BiotechnologyBN/Bertus Beaumont LabQN/van der Zant La
材料、颜色与空间: 博图斯·穆德的施罗德住宅修复理念
No full textRietveld Schröder House is one of the most representative work of the Dutch De Stijl movement. The house represents Mrs Schröder’s pursuit of a modern, open lifestyle. Moreover, it is also the first batch of restored modern architectural heritage, which is a milestone for Dutch and even worldwide architectural protection. Bertus Mulder is the leading architect responsible for the restoration. This article puts him in the context of the development of modern Dutch architectural protection theory and examines his guiding ideology, choices, results, and omissions, as well as the role of the Schröder family. Mulder focused on the restoration of the initial abstract space of the restored home, and this resulted in a drastic repair of the color and materials, as well as the removal of the household life history. A comprehensive reflection on his work will be helpful for future restoration of modernist architectural heritage.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Heritage & Value
Federalism in South Sudan—Options for Power Sharing in the Permanent Constitution
No full text© The Author(s) 2013.The young nation of South Sudan is currently engaged in a review of its Transitional Constitution with the aim of finalizing a Permanent Constitution by 2015. One of the key issues the subject of negotiations is whether the Permanent Constitution should contain power-sharing features and if so, whether those features should be formal or informal. While it is widely accepted that the Permanent Constitution will contain federal elements, this article gives consideration to the way in which formal and informal power-sharing arrangements that are found in federations such as Nigeria, South Africa and Ethiopia, could be employed by South Sudan

De restauraties van het Rietveld Schröderhuis: Een reflectie
Get PDFThe Rietveld Schröder House (1924) in Utrecht is the only private home among the ten UNESCO World Heritage sites in the Netherlands. In 1987 it was opened to the public as a museum house and since 2013 it has been part of the collection of Utrecht’s Centraal Museum. The world-famous house was designed by the architect Gerrit T. Rietveld (1888-1964) in close collaboration with the client, Truus Schröder-Schräder (1889-1985). During the 1970s and ’80s the house was comprehensively restored by the architect Bertus Mulder (b. 1929), who had worked with Rietveld for a brief period in the early 1960s. Thanks to a Keeping it Modern Grant from the Getty Foundation these restorations have now been put on a sound scientific footing by means of archival research, technical analysis and oral historyHeritage & Value
