Indonesia is undergoing major policy changes, seeking to expand social forestry designations from less than 1% (1.1 million hectares) to over 10% (12.7 million hectares) of the Forest Estate. Expanding designations is at once a landmark reform and a call for caution, raising questions about policy intentions, and practical concerns about legal, technical, and implementation mechanisms. Social forestry literature highlights three key tenets, namely efforts that: confer rights to local communities, support livelihoods, and achieve conservation outcomes. This paper examines social forestry implementation from a cross-section of sites in South Sulawesi by reflecting on sustained action research between 2012-2016. The approach critically juxtaposes social forestry policy intent with implementation at three different sites. Findings indicate social forestry implementation suffers from historically problematic state enclosures and flawed land administration processes, entrenched politicaleconomic interests among local actors, and lack of institutional engagement beyond the permitting process. Shortcuts to addressing entrenched conflict will only heighten tensions or further marginalize the most vulnerable, without guarantees to conservation outcomes.
Iron oxide minerals are probable constituents of the sediments present in geothermal regions of the primitive earth. They might have adsorbed different organic monomers (amino acids, nucleotides etc.) and catalyzed polymerization processes leading to the formation of the first living cell. In the present work we tested the catalytic activity of three forms of iron oxides (Goethite, Akaganeite and Hematite) in the intermolecular condensation of each of the amino acids glycine and L-alanine. The effect of zinc oxide and titanium dioxide on the oligomerization has also been studied. Oligomerization studies were performed for 35 days at three different temperatures 50, 90 and 120°C without applying drying/wetting cycling. The products formed were characterized by HPLC and ESI-MS techniques. All three forms of iron oxides catalyzed peptide bond formation (23.2% of gly2 and 10.65% of ala2). The reaction was monitored every 7 days. Formation of peptides was observed to start after 7 days at 50°C. Maximum yield of peptides was found after 35 days at 90°C. Reaction at 120°C favors formation of diketopiperazine derivatives. It is also important to note that after 35 days of reaction, goethite produced dimer and trimer with the highest yield among the oxides tested. We suggest that the activity of goethite could probably be due to its high surface area and surface acidity.
Interaction of ribonucleotides--namely, 5'-AMP, 5'-GMP, 5'-CMP, and 5'-UMP--with acidic, neutral, and basic alumina has been studied. Purine nucleotides showed higher adsorption on alumina in comparison with pyrimidine nucleotides under acidic conditions. Adsorption data obtained followed Langmuir adsorption isotherm, and X(m) and K(L) values were calculated. On the basis of infrared spectral studies of ribonucleotides, alumina, and ribonucleotide-alumina adducts, we propose that the nitrogen base and phosphate moiety of the ribonucleotides interact with the positive charge surface of alumina. Results of the present study may indicate the importance of alumina in concentrating organic molecules from dilute aqueous solutions in primeval seas in the course of chemical evolution on Earth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
