  • Indonesia's Moratorium on Palm Oil Expansion from Natural Forests: Economy-Wide Impacts and the Role of International Transfer
    Indonesia’s Moratorium on Palm Oil Expansion from Natural Forests: Economy-Wide Impacts and the Role of International Transfers Arief A. Yusuf,Elizabeth L. Roos, and Jonathan M. Horridge∗ Indonesia has introduced a moratorium on the conversion of natural forests to land used for palm oil production. Using a dynamic, bottom-up, interregional computable general equilibrium model of the Indonesian economy, we assess several scenarios of the moratorium and discuss its impacts on the domestic economy as well as on regional economies within Indonesia. We find the moratorium reduces Indonesian economic growth and other macroeconomic indicators, but international transfers can more than compensate the welfare losses. The impacts also vary across regions. Sumatra, which is highly dependent on palm oil and is home to forests that no longer have a high carbon stock, receives fewer transfers and suffers the greatest economic loss. Kalimantan, which is relatively less dependent on palm oil and has forests with a relatively high carbon stock, receives more transfers and gets greater benefit. This implies that additional policy measures anticipating the unbalanced impacts of the moratorium are required if the trade-off between conservation and reducing interregional economic disparity is to be reconciled. Keywords: carbon emissions, computable general equilibrium, Indonesia, palm oil JEL codes: R10, R11, R13 I. Introduction The United Nations Reduction of Emissions from Deforestation and Forest Degradation (REDD) program seeks to reduce carbon emissions resulting from deforestation and enhance carbon stocks in forests, while also contributing to national sustainable development (UN-REDD 2015).

D.* Department of Biochemistry, Dr. Ambedkar Veedhi Bangalore University, Bangalore - 560001, India. Accepted 17 June, 2011 The continued demand for edible oils by the ever increasing population makes it pertinent to explore new sources. In this direction, two new edible oils namely palm oil and rice bran oil have been subjected to nutritional and toxicological evaluations of their chemicals constituents. An attempt has been made in this article to assess the acceptability of the two oils based on the various investigations that have been carried out so far. Key words: Palm oil, rice bran oil, anti-oxidants, cholesterol fatty acids, phospholipids, tocopherols, oryzanol, cardiovascular diseases. INTRODUCTION Vegetable oils are the main source of dietary fat for Among the oils under consideration, palm oil and rice almost all sections of the Indian population and there is a bran oil offer great scope in India, as they are widely continued growing demand from both caterers and con- preferred by the vanaspathi industries and also by the sumers.

Design: Eva Kok Translation: Ninette de Zylva (editing) Printed by: Digigrafi, Wageningen, the Netherlands ISBN Agromisa: 90-8573-027-9 ISBN CTA: 92-9081-327-X Foreword Non-timber forest products (NTFPs) are wild plant and animal pro- ducts harvested from forests, such as wild fruits, vegetables, nuts, edi- ble roots, honey, palm leaves, medicinal plants, poisons and bush meat. Millions of people – especially those living in rural areas in de- veloping countries – collect these products daily, and many regard selling them as a means of earning a living. This Agrodok presents an overview of the major commercial wild plant products from Africa, the Caribbean and the Pacific. It explains their significance in traditional health care, social and ritual values, and forest conservation. It is designed to serve as a useful source of basic information for local forest dependent communities, especially those who harvest, process and market these products. We also hope that this Agrodok will help arouse the awareness of the potential of NTFPs among development organisations, local NGOs, government officials at local and regional level, and extension workers assisting local communities. Case studies from Cameroon, Ethiopia, Central and South Africa, the Pacific, Colombia and Suriname have been used to help illustrate the various important aspects of commercial NTFP harvesting.

  • London's Soap Industry and the Development of Global Ghost Acres
    London’s Soap Industry and the Development of Global Ghost Acres in the Nineteenth Century John Knight won a prize medal at the Great Exhibition in 1851 for his soaps, which included an ‘excellent Primrose or Pale-yellow-soap, made with tallow, American rosin, and soda’.1 In the decades that followed the prize, John Knight’s Royal Primrose Soap emerged as one of the United Kingdom’s leading laundry soap brands. In 1880, the firm moved down the Thames from Wapping in East London to a significantly larger factory in West Ham’s Silvertown district.2 The new soap works was capable of producing between two hundred and three hundred tons of soap per week, along with a considerable number of candles, and extracting oil from four hundred tons of cotton seeds.3 To put this quantity of soap into context, the factory could manufacture more soap in a year than the whole of London produced in 1832.4 The prize and relocation together represented the industrial and commercial triumph of this nineteenth-century family business. A complimentary article from 1888, argued the firm’s success rested on John Knights’ commitment ‘to make nothing but the very best articles, to sell them at the very lowest possible prices, and on no account to trade beyond his means’.5 The publication further explained that before the 1830s, soap ‘was dark in colour, and the 1 Charles Wentworth Dilke, Exhibition of the Works of Industry of All Nations, 1851: Catalogue of a Collection of Works On, Or Having Reference To, the Exhibition of 1851, 1852, 614.

Received: 6 April 2020; Accepted: 10 May 2020; Published: 14 May 2020 Abstract: The consumers’ opinion concerning conventional palm (Elaeis guineensis) oil is negatively affected by environmental and nutritional issues. However, oils extracted from drupes of interspecific hybrids Elaeis oleifera E. guineensis are getting more and more interest, due to their chemical and × nutritional properties. Unsaturated fatty acids (oleic and linoleic) are the most abundant constituents (60%–80% of total fatty acids) of hybrid palm oil (HPO) and are mainly acylated in position sn-2 of the glycerol backbone. Carotenes and tocotrienols are the most interesting components of the unsaponifiable matter, even if their amount in crude oils varies greatly. The Codex Committee on Fats and Oils recently provided HPO the “dignity” of codified fat substance for human consumption and defined the physical and chemical parameters for genuine crude oils. However, only few researches have been conducted to date on the functional and technological properties of HPO, thus limiting its utilization in food industry. Recent studies on the nutritional effects of HPO softened the initial enthusiasm about the “tropical equivalent of olive oil”, suggesting that the overconsumption of HPO in the most-consumed processed foods should be carefully monitored.

Accepted 22 November, 2012 Kenyan tea (Camellia sinensis) is widely grown for its leaves and is commercialized as black tea. Product diversification and value addition is currently an area of great interest. This study provides data on the physico-chemical properties of Kenyan tea seed oil from selected clones of tea seeds to ascertain its potential applications. Soxhlet extraction using hexane was employed to obtain tea seed oil followed by chemical analysis to assess its properties. Oil yield, iodine value, saponification value, peroxide value, free fatty acids, total polyphenols and antioxidant activity were determined. The oil yields ranged between 16 to 25% w/w. Iodine value was in the range of 86 to 91 g I2/100 g, peroxide value < 3.5 meq O2/kg, saponification value between 182 to 187 mg KOH/g, free fatty acid < 1.5% oleic acid, total polyphenols 0.036 to 0.043 mg/L gallic acid and antioxidant activity of between 14 to 21% 2,2- diphenyl-1-picrylhydrazyl (DPPH) scavenging activity.

  • On Palm Oil and Deforestation in Borneo
    On Palm Oil and Deforestation in Borneo: A Step-Wise Model- Based Policy Analysis Yola Riana Effendi, Bramka Arga Jafino, Erik Pruyt Delft University of Technology - Faculty of Technology, Policy and Management Jaffalaan 5, 2626 BX, Delft, The Netherlands [email protected], [email protected], [email protected] ABSTRACT Deforestation due to the increasing palm oil demand has been a major environmental issue in Indonesia, especially in Kalimantan on Borneo Island, where the growth of oil palm plantation is the highest. As the potential for oil palm plantations in Sumatra Island has been reached, expansion has moved to Kalimantan where forest coverage is still relatively high. Besides logging trees, land is cleared by burning the forest without proper procedures and neglecting the environmental surroundings of the forest. Consequently, the fire spreads and affects surrounding areas. This study attempts to explore the long-term dynamics of the forest coverage in Kalimantan and to design policies to reduce the damage caused by this expansion. Using a model-based adaptive robust design approach, we show that it is possible to reduce the percentage of simulation runs which forest coverage in 2100 is smaller than 15 million hectares from more than 80% to less than 15%. Ultimately, the percentage of simulation runs which forest coverage is less than 10 million hectares is even smaller than 2% after the final policies are executed. Keywords: palm oil, Borneo, deforestation, system dynamics, deep uncertainty, adaptive robust design I. BACKGROUND Palm oil constitutes the largest share of vegetable oil produced in the world because palm tree has the biggest yield of oil extraction compared to other crops.
