Discourses on the performance gap of agriculture in a green economy: a Q-methodology study in Indonesia

ABSTRACT Gaps exist between aspirations of ‘green agriculture’, which protects biodiversity and ecosystem services, and the reality on the ground. Using Q-methodology, we explored expert opinion in Indonesia on the contributing factors to the gaps. Q-methodology indicated three dominant discourses on ‘green agriculture’ and groups of experts who prioritize them: (1) endorsers of regulations and innovations; (2) providers of resources for access to capital, technology and knowledge; and (3) proponents of green economy (GE) and land-use planning (LUP). Group 1 pointed out the importance of endorsing incentives to reduce the gap, while Group 2 reckoned that building smallholders’ capacity and providing them with access to capital, technology, and knowledge are needed to green agricultural practices. Group 3 described the importance of integrating environmental value into the gross domestic product and earmarking sources derived from environmental levies for greening the agricultural sector. All discourses recognized the importance of scientific policy formulation. Groups 1 and 3 agreed that non-synchronization of LUP between national and local governments highly contributes to the gap. Groups 2 and 3 perceived that ecosystem services from the agricultural sector have not been sufficiently understood to promote green agricultural development. By simultaneously addressing the gaps on each level and understanding how each factor contributes to the gap, we propose a set of recommendations to improve the implementation of green agriculture in Indonesia by creating a platform that all three groups can recognize and support.

Aboveground carbon stocks in oil palm plantations and the threshold for carbon-neutral vegetation conversion on mineral soils

Abstract The carbon (C) footprint of palm oil production is needed to judge emissions from potential biofuel use. Relevance includes wider sustainable palm oil debates. Within life cycle analysis, aboveground C debt is incurred if the vegetation replaced had a higher C stock than oil palm plantations. Our study included 25 plantations across Indonesia, in a stratified study design representing the range of conditions in which oil palm is grown. From allometric equations for palm biomass and observed growth rates, we estimated the time-averaged aboveground C stock for 25-year rotation and 95%-confidence interval to be 42.07 (42.04–42.10) Mg C ha−1 for plantations managed by company on mineral soils, 40.03 (39.75–40.30) Mg C ha−1 for plantations managed by company on peat, and 37.76 (37.42–38.09) Mg C ha−1 for smallholder oil palm on mineral soils. Oil palm can be established C debt-free on mineral soils with aboveground C stocks below these values; neutrality of mineral soil C pools was documented in a parallel study. Acknowledging variation in shoot:root ratios, the types of vegetation that can be converted debt-free to oil palm include grasslands and shrub, but not monocultural rubber plantations, rubber agroforest, and similar secondary or logged-over forests of higher C stock.

Climate-smart land use requires local solutions, transdisciplinary research, policy coherence and transparency

ABSTRACT Successfully meeting the mitigation and adaptation targets of the Paris Climate Agreement (PA) will depend on strengthening the ties between forests and agriculture. Climate-smart land use can be achieved by integrating climate-smart agriculture (CSA) and REDD+. The focus on agriculture for food security within a changing climate, and on forests for climate change mitigation and adaptation, can be achieved simultaneously with a transformational change in the land-use sector. Striving for both independently will lead to competition for land, inefficiencies in monitoring and conflicting agendas. Practical solutions exist for specific contexts that can lead to increased agricultural output and forest protection. Landscape-level emissions accounting can be used to identify these practices. Transdisciplinary research agendas can identify and prioritize solutions and targets for integrated mitigation and adaptation interventions. Policy coherence must be achieved at a number of levels, from international to local, to avoid conflicting incentives. Transparency must lastly be integrated, through collaborative design of projects, and open data and methods. Climate-smart land use requires all these elements, and will increase the likelihood of successful REDD+ and CSA interventions. This will support the PA as well as other initiatives as part of the Sustainable Development Goals.
