The Relationship

Nipa palm (Nypa fruticans Wurmb.) widely recognized as one of the biological resources with various aspect of utilization. Nipa palm sap can be processed into bioethanol. Bioethanol also has a quite high selling price, especially for the fulfilment of energy and for fossil fuels substitution. The main purpose of the study was to evaluate the economic value of nipa sap for further processed into bioethanol, in order to improve the income and job opportunity of coastal households. This research was conducted at Sungsang, South Sumatera with focusing on nipa palm sap further processing into bioethanol and its impact on increasing household income. This research was statistically testing the relationship between potential production of bioethanol, average revenue and labour recruitment. Based on the 2013 data, potential production of bioethanol was capable to contribute of nett income about IDR 507,940 to 3,503,280 ha-1 month-1 or IDR 6,095,274 to 42,039,360 ha-1 year-1. Therefore each hectare of nipa palm can generate labour recruitment up to 3.7 person ha-1. This assessment was expected to provide a better description of the importance of local biological resources utilization of the nipa palm, in order to improve community welfare and the efforts of biodiversity conservation on a local scale.

Repong Damar is a plot of land planted with various types of productive plants from various types of timber with economic value. The term repong damar is because the plant that is dominated by this plot of land is damar eye cat (Shorea javanica). The cat's eye resin tree (Shorea javanica) produces a type of non-wood forest product in the form of resin. Resin damar is one of the mainstay commodities which is a source of income for the community because it can produce in a short period and has sustainable management compared to other types of plants found in Repong Damar. Pesisir Barat Regency, Lampung Province. The research objective was to determine the relationship between the harvesting period and the quantity and quality of resin damar which affects the income of resin farmers in Labuhan Mandi, Pesisir Barat Regency, Lampung Province. Data collection was carried out in June-August 2020. The sampling used in this study was purposive. This method was chosen to obtain uniformity in terms of the same growing area, a form of management, and plant genetic factors. The data were taken in the form of resin/tree quantity in 3 harvesting periods, namely a) 2 weeks; b) 3 weeks; c) 4 weeks, the percentage of resin quality based on market quality, namely 1) AB; 2) C; 3) D; 4) E; 5) ash; and the selling price of resin at the farmer level for each quality. Data analysis was performed using quantitative methods to calculate the amount of resin production, percentage of resin quality, and farmer income. The results showed that a harvest period of 4 weeks produced the highest resin quantity/month compared to a harvesting period of 3 weeks and a harvesting period of 2 weeks. The 4 week harvesting period also provides a higher percentage of AB resin quality than the 3 week harvesting period and the 2 week harvesting period, therefore the 4 week harvesting period provides higher farmer income than the 3 week harvesting period and 2 week harvesting period. Keywords: income, quality, quantity, resin damar AbstrakRepong Damar merupakan sebidang lahan yang ditanami oleh berbagai jenis tanaman produktif dari berbagai jenis kayu yang bernilai ekonomis.  Penyebutan repong damar karena tanaman yang didominasi pada sebidang lahan tersebut yaitu damar mata kucing (Shorea javanica).  Pohon damar mata kucing (Shorea javanica) menghasilkan salah satu jenis hasil hutan bukan kayu berupa resin.  Resin damar merupakan salah satu komoditi andalan yang menjadi sumber pendapatan masyarakat karena dapat menghasilkan dalam jangka waktu yang singkat dan pengelolaan berkelanjutan dibandingkan jenis tanaman lain yang terdapat di Repong Damar.

This chapter looks at a postsocialist fishery in Kazakhstan to explore the relationship between property rules designed to manage natural resources, and practices of resource exploitation. The Aral Sea is famous for its desiccation over the second half of the twentieth century, which stemmed from Soviet irrigation projects; in 2006 a World Bank/Republic of Kazakhstan project restored a small part of the sea, and fish catches have recently recovered somewhat. In this chapter, based on ethnographic and archival research, I explore the disjuncture between formal rules and practice to address debates about the management of common-pool resources. Within the nomadic economy, in contrast to livestock, fish were not property objects; over the colonial, Soviet and post-Soviet periods, they became objects of economic value in different ways, mediating different sorts of social relations. Turning to the contemporary property regime, I suggest that formal rules matter, but in unintended ways.

Volunteer Time

The economic value of volunteering is an increasingly important part of volunteering management. It has become part of public policies. Some requests for proposals (RFP) enable nonprofits to include the value of volunteer time in compulsory co-financing. These RFP include the European Economic Area (EEA) Grants and Norway Grants. This article addresses the relationship in the value of volunteering, also called in-kind volunteering contributions. The research includes two case studies of finances from EEA and Norway Grants in the Czech Republic: the Czech NGO Programme, responsible for allocating grants between 2009 and 2014, and the Active Citizens Fund, responsible for allocating grants between 2014 and 2021. They share elements through the EEA and Norway Grants rules. However, they use different types of specialist replacement wages. The article summarizes the arguments for including in-kind volunteering contributions. It presents the possible values of these contributions in the selected cases, including the relationship between the type of volunteering and the number of hours necessary to achieve these values. The article defines the theoretical basis for calculating the value of in-kind volunteer contributions and illustrates this with real examples of allocations from EEA and Norway Grants.

Basin Scale

This paper presents a methodology to project irrigation and domestic water demands on a regional to global scale, in terms of both quantity and economic value. Projections are distributed at the water basin scale. Irrigation water demand is projected under climate change. It is simply computed as the difference between crop potential evapotranspiration for the different stages of the growing season and available precipitation. Irrigation water economic value is based on a yield comparison approach between rainfed and irrigated crops using average yields. For the domestic sector, we project the combined effects of demographic growth, economic development and water cost evolution on future demands. The method consists in building three-part inverse demand functions in which volume limits of the blocks evolve with the level of GDP per capita. The value of water along the demand curve is determined from price-elasticity, price and demand data from the literature, using the point-expansion method, and from water cost data. This generic methodology can be easily applied to large-scale regions, in particular developing regions where reliable data are scarce. As an illustration, it is applied to Algeria, at the 2050 horizon, for demands associated to reservoirs. Our results show that domestic demand is projected to become a major water consumption sector. The methodology is meant to be integrated into large-scale hydroeconomic models, to determine inter-sectorial and inter-temporal water allocation based on economic valuation.

Herlang Subdistrict is the largest producer of coconut juice (along with Selayar Regency and JenepontoRegency) which is the raw material for coconut sugar production in South Sulawesi. Tugondeng Village is one ofthe villages in Herlang District. About 80% of Tugondeng villagers work in the coconut sugar manufacturingindustry. However, this potential has not well developed due to the low economic value of brown sugar. To increasethe selling price of coconut sugar produced by Tugondeng Village, efforts need to be made to process coconut sapand coconut sugar into products which have higher selling price, namely palm sugar. The steps taken to achieve theobjectives of this activity were : (a) presentation of material on how to process coconut sap and coconut sugar intopalm sugar; and (b) demonstration of preparing palm sugar from coconut sap and coconut sugar. The resultsobtained show that the process of making palm sugar from coconut sap and coconut sugar is quite simple and thepalm sugar produced has longer shelf-life than coconut sugar

The study was conducted to find out the suitability of making particleboard using nipa palm (Nypa fruticans) stem wood and rajkoroi (Albizia richardiana) wood chips. Particleboards were fabricated at six different ratios of nipa palm stem and rajkoroi wood chips such as 100:0, 75:25, 50:50, 25:75, 10:90 and 0:100. Characteristics of particleboards such as modulus of rupture, internal bond strength, water absorption, thickness swelling and moisture content were measured. Results shows that particleboards made from 100% rajkoroi wood chips have the highest static bending properties and highest tensile strength properties of other particleboards but 100% nipa palm stem wood chips have the lowest static bending and lowest tensile strength properties of other particleboards. 10% nipa palm stem wood chips particleboard have the highest bending strength and tensile strength is better than 100% nipa palm stem wood chips and other mixing chips of particleboards. Mechanical, water resistance and dimensional stability properties were tested according to Indian standard specification. Tensile strength passed the British and German standard specification and nearest to Bureau of Indian Standard, bending strength was found nearest to Indian Standard but lower than German and British Standard specification. Strength property of rajkoroi wood chips particleboard is higher than nipa palm steam wood chips particleboard but dimensional stability is lower than nipa palm steam wood chips particleboard.

The Relationship

We develop a new conceptual framework to analyze the evolution of the relationship between cultural production and different forms of economic and social value creation in terms of three alternative socio-technical regimes that have emerged over time. We show how, with the emergence of the Culture 3.0 regime characterized by novel forms of active cultural participation, where the distinction between producers and users of cultural and creative contents is increasingly blurred, new channels of social and economic value creation through cultural participation acquire increasing importance. We characterize them through an eight-tier classification, and argue on this basis why cultural policy is going to acquire a central role in the policy design approaches of the future. Whether Europe will play the role of a strategic leader in this scenario in the context of future cohesion policies is an open question.

Fish Farms

Brazilian fish farms presented an accelerated development during the early 90's, mainly because of the increase in fee-fishing operations. To meet the demand of this market, fish production and supply became excessive and, as a consequence, the number of fee-fishing operations, farmers and the final selling price, decreased. This study analyzes the technical aspects, production cost, profitability and economic viability of the production of piauçu (L. macrocephalus) in ponds, based on information from a rural property. Feeding and fingerling costs amount to approximately 47.1% of the total production cost, representing together with the final selling price the most important factor affecting profitability. The payback period was 8.3 years, the liquid present value US$ 291.07, the internal return margin 9%, and the income-outcome ratio was 1.01, which represents an unattractive investment as a projection based on current conditions. The improvement in productive efficiency enhances the economic valuation index, and that the relative magnitude of cost and income are the most important points for the economic viability of the studied farm.
