Decoupling resource use efficiency and ecological impacts are two challenges of oil palm smallholders in Indonesia. This study aims to find option for increasing productivity among smallholder and to reduce the environmental impacts of nutrient management in their plantations. We adopted UNEP's definition of resource and impact decoupling as a tool to estimate resource decoupling rate and impact decoupling rate. The average smallholder's resource decoupling rate from 2013 to 2017 is 0.86 kg fertilizer/kg fresh fruit bunch. This rate is 93.48% of the average of the companies (0.92 kg fertilizer/kg fresh fruit bunch) for the same period. Reducing the fertilizers dosages will reduce the resource decoupling rate and the impact decoupling rate by 58.14% (from 0.86 to 0.36 kg fertilizer/kg fresh fruit bunch) and by 67.32% (from 3.06 to 1.10 g CO 2 e/kg fresh fruit bunch) respectively. Reducing the fertilizer dosage is the most appropriate approach to increasing the resource and impact decoupling rates. We conclude that a smallholder is able to produce fresh fruit bunches sustainably by changing nutrient management practices and increasing access to certified planting material. Further study is required to include the influence of land use change on the impact decoupling rate as this factor was not included in our analysis.
A B S TR A C TThe status of the availability of water resources in DKI (Indonesia's Special Region of) Jakarta has reached a critical phase. Determination of progressive tariffs by the DKI Jakarta Provincial Government in 2007 aimed to encourage water users to use water resources rationally and in a sustainable way. However, since the launch of the policy, there has been no evaluation to determine the effectiveness of these progressive tariffs. This research analysed empirical data to examine the effect of policy interventions on water use behaviour in DKI Jakarta. An analysis was carried out by calculating water usage before progressive tariffs were applied and comparing them to water use after the tariffs were applied. Another analysis calculated the number of customers before and after the implementation of progressive tariffs and compared the changes. The increase in water prices plotted are stated in nominal value by assuming the average level of inflation in Jakarta (especially the price of water) was nearly under 2 percent and the price of water was not controlled by the market mechanism The results of this study indicate that before progressive tariffs were applied, water consumption had declined despite an increase in the number of customers, however, water consumption increased after the implementation. This shows that progressive tariffs are effective instruments to distribute clean water access through cross-subsidies, however, it has no effect on consumption levels. KEY WORDS: progressive water tariff, urban water supply, water use efficiency, water demand management ARTICLE HISTORY:
Balancing efficiency and sustainability of fresh fruit bunches (FFB) production remains a critical issue facing by oil palm (Elaeis guineensis Jacq.) producing countries like Indonesia. To address those issue, we analyze trade-offs of those 2 variables in plantation managed by smallholders and compare the result to the one of the companies. The trade-offs are estimated by dividing the GHG emission to the partial factor productivity (PFP) of FFB production based on data from previous LCA assessment. Our study revealed that current practices implementing by smallholders are economically less efficient and ecologically unsustainable comparing from the FFB production practices implementing by companies. For smallholders, the trade-offs of ecological impact and economic efficiency reached 0.86 kg CO2-eq/kg FFB or 2.6 times from the trade-offs of FFB production by companies (0.33 kg CO2-eq/kg FFB). Several changes in nutrient management such as adjusting the fertilizers rate at smallholders in Sumatera, improving the OER from 0.20 to 0.22 for smallholders and from 0.21 to 0.22 for companies, and applying biochar technology are the most promising practices to minimize the trade-off up to 81%.
A paradigm shift is required to transform current natural resource management (NRM) in Indonesia’s decision to move into low-carbon development to achieve the greenhouse gas emission target. No study has been conducted to assess whether or not the current approaches are reliable in anticipating the conundrum of the new juncture. We reviewed 10 cases of NRM practices in Indonesia from 2019–2023 collected from the Scopus dataset by integrating the prisoner’s dilemma approach into the socio-ecological framework to analyze the practices and the anticipated gaps. Our finding revealed that socio-economic governance is the dominant view in interpreting the competition between personal and collective interests in NRM. Seeing NRM as an allocation problem and the excessive use of the legal normative approach in interpreting and addressing the problem are flaws in the approach. Combining the prisoner’s dilemma approach with the socio-ecological governance framework enabled us to address the flaws. Promoting polycentric governance that accommodates social trust, reciprocities, and socio-ecological beliefs and reduces uncertainties about ownership and the resources necessary to reduce defective behavior is a solution to transform the structure of the competition. Revising the socio-economic payoff into a socio-ecological value-oriented institution is the strategy to address the conundrum.
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.
