The Strategy of Shifting Cultivators in West Kalimantan in Adapting to the Market Economy: Empirical Evidence Behind Gaps in Interdisciplinary Communication
The strategy of shifting cultivators in West Kalimantan in adapting to the market economy: empirical evidence behind gaps in interdisciplinary communication Prudensius Maring1 Budi Luhur University, Indonesia Abstract Issues of climate change and expansion of large-scale land acquisition for industrial plantations continue to ravage the shifting cultivation system that 300–500 million subsistence farmer households depend on. In Indonesia, particularly in Kalimantan and Sumatera, village communities continue to practice shifting cultivation amidst the conversion of lands into industrial plantations. The rampant conversion of farmer's land by large scale companies based in the market economy has resulted in the decline of the shifting cultivation system, and compelled them to enter commercial production. I employed qualitative methods, conducting in- depth interviews and observations in West Kalimantan in 2018. Shifting cultivation today is not just for subsistence, but it is also a strategy to maintain claims to land that has been handed over to companies. Concurrently, people have been developing community plantations using industrial commodities such as rubber and oil palm, which still incorporate subsistence features. The changes occurring in villages have led to conflict since land availability has reduced, while the alternative of working for forestry and plantation companies is hampered by their lack of skills and knowledge. Theoretically, this study indicates the need for communication and synergy between the perspectives of political ecology and cultural ecology in order to understand the socio-politico-economic complexities haunting the village community's alterations in subsistence strategies. The practical implications are that land-based village development should open up communication among stakeholders and position village communities as the key beneficiary in the long run. -
The Following Carcinogenic Essential Oils Should Not Be Used In
Aromatherapy Undiluted- Safety and Ethics Copyright © Tony Burfield and Sylla Sheppard-Hanger (2005) [modified from a previous article “A Brief Safety Guidance on Essential Oils” written for IFA, Sept 2004]. Intro In the last 20 years aromatherapy has spread its influence to the household, toiletries and personal care areas: consumer products claiming to relax or invigorate our psyche’s have invaded our bathrooms, kitchen and living room areas. The numbers of therapists using essential oils in Europe and the USA has grown from a handful in the early 1980’s to thousands now worldwide. We have had time to add to our bank of knowledge on essential oils from reflecting on many decades of aromatherapeutic development and history, the collection of anecdotal information from practicing therapists, as well as from clinical & scientific investigations. We have also had enough time to consider the risks in employing essential oils in therapy. In the last twenty years, many more people have had accidents, been ‘burnt’, developed rashes, become allergic, and become sensitized to our beloved tools. Why is this? In this paper, we hope to shed light on this issue, clarify current safety findings, and discuss how Aromatherapists and those in the aromatherapy trade (suppliers, spas, etc.) can interpret this data for continued safe practice. After a refresher on current safety issues including carcinogenic and toxic oils, irritant and photo-toxic oils, we will look at allergens, oils without formal testing, pregnancy issues and medication interactions. We will address the increasing numbers of cases of sensitization and the effect of diluting essential oils. -

As elucidated by gas chromatography/flame ionization detector (GC/FID) and gas chromatography/mass spectrometry (GC/MS methods), the juniper berry oil from Bulgaria is largely comprised of monoterpene hydrocarbons such as α-pinene (51.4%), myrcene (8.3%), sabinene (5.8%), limonene (5.1%) and β-pinene (5.0%). -

Use of Undiluted Tea-Tree Oil As a Cosmetic
Federal Institute for Risk Assessment (BfR) Use of undiluted tea-tree oil as a cosmetic Opinion of the Federal Insitute for Risk Assessment (BfR), 1th September 2003 Background Recently there has been an increasing amount of reports on contact-allergic eczema in con- junction with the use of tea-tree oil. Tea-tree oil is sold as a pure natural product, highly con- centrated and undiluted in cosmetics. Tea-tree oil is advertised as a universal remedy al- though there is no marketing authorisation as a pharmaceutical product. Concentrated tea-tree oil has been classified as harmful according to the self-classification of the International Fragrance Association (IFRA) and is labelled with R-phrases R 22 (harmful if swallowed) R 38 (irritating to skin) and R 65 (may cause lung damage if swallowed) as well as the symbol Xn (harmful) (IFRA Labelling Manual 1, 2001). These indications of health hazards are also part of the safety data sheets of raw material suppliers. At the 65th and 66th meetings of the Cosmetics Committee at the Federal Institute for Risk Assessment (BfR), health risks associated with the use of undiluted and highly concentrated tea-tree oil in cosmetic products were discussed extensively. Result Tea-tree oil is a mixture of various terpenes extracted from the Australian tea-tree. Undiluted tea-tree oil is a pure natural product. In the presence of atmospheric oxygen but also when exposed to light and higher temperatures, oxidation processes occur leading to the formation of peroxides, epoxides and endoperoxides which have a sensitising potency and may trigger allergic skin reactions. -

We have reviewed the successful use of different chemical methods for the botanical authentication of 2,386 commercial herbal products, sold in 37 countries spread over six continents. The majority of the analyzed products were reported to be authentic (73%) but more than a quarter proved to be adulterated (27%).
