Ecosystems provide a wide range of goods, services or ecosystem services (ES) to society. Estimating the impact of land use and land cover (LULC) changes on ES values (ESV) is an important tool to support decision making. This study used remote sensing and GIS tools to analyze LULC change and transitions from 2001 to 2016 and assess its impact on ESV in a tropical forested landscape in the southern plains of Nepal. The total ESV of the landscape for the year 2016 is estimated at USD 1264 million year-1. As forests are the dominant land cover class and have high ES value per hectare, they have the highest contribution in total ESV. However, as a result of LULC change (loss of forests, water bodies, and agricultural land), the total ESV of the landscape has declined by USD 11 million year-1. Major reductions come from the loss in values of climate regulation, water supply, provision of raw materials and food production. To halt the ongoing loss of ES and maintain the supply and balance of different ES in the landscape, it is important to properly monitor, manage and utilize ecosystems. We believe this study will inform policymakers, environmental managers, and the general public on the ongoing changes and contribute to developing effective land use policy in the region.

Water-to-air carbon dioxide fluxes from tropical coastal waters are an important but understudied component of the marine carbon budget. Here, we investigate drivers of carbon dioxide partial pressure (pCO2) in a relatively pristine mangrove-seagrass embayment on a tropical island (Bali, Indonesia). Observations were performed over eight underway seasonal surveys and a fixed location time series for 55 h. There was a large spatial variability of pCO2 across the continuum of mangrove forests, seagrass meadows and the coastal ocean. Overall, the embayment waters surrounded by mangroves released CO2 to the atmosphere with a net flux rate of 18.1 ± 5.8 mmol m-2 d-1. Seagrass beds produced an overall CO2 net flux rate of 2.5 ± 3.4 mmol m-2 d-1, although 2 out of 8 surveys revealed a sink of CO2 in the seagrass area. The mouth of the bay where coral calcification occurs was a minor source of CO2 (0.3 ± 0.4 mmol m-2 d-1). The overall average CO2 flux to the atmosphere along the transect was 9.8 ± 6.0 mmol m-2 d-1, or 3.6 × 103 mol d-1 CO2 when upscaled to the entire embayment area. There were no clear seasonal patterns in contrast to better studied temperate systems. pCO2 significantly correlated with antecedent rainfall and the natural groundwater tracer radon (222Rn) during each survey. We suggest that the CO2 source in the mangrove dominated upper bay was associated with delayed groundwater inputs, and a shifting CO2 source-sink in the lower bay was driven by the uptake of CO2 by seagrass and mixing with oceanic waters. This differs from modified landscapes where potential uptake of CO2 is weakened due to the degradation of seagrass beds, or emissions are increased due to drainage of coastal wetlands.

Bioenergy production from degraded land provides an opportunity to secure a new renewable energy source to meet the rapid growth of energy demand in Indonesia while turning degraded land into productive landscape. However, bioenergy production would not be feasible without landowner participation. This study investigates factors affecting landowners’ preferences for bioenergy production by analyzing 150 landowners with fire experience in Buntoi village in Central Kalimantan using Firth’s logistic regression model. Results indicated that 76% of landowners preferred well-known species that have a readily available market such as sengon (Albizia chinensis (Osb.) Merr.) and rubber tree (Hevea brasiliensis Müll.Arg.) for restoration on degraded land. Only 8% of preferred nyamplung (Calophyllum inophyllum L.) for bioenergy production; these particular landowners revealed a capacity to handle the uncertainty of the bioenergy market because they had additional jobs and income, had migrated from Java where nyamplung is prevalent, and preferred agricultural extension to improve their technical capacity. These results contribute to identifying key conditions for a bottom-up approach to bioenergy production from degraded land in Indonesia: a stable bioenergy market for landowners, application of familiar bioenergy species, and agricultural extension support for capacity building.

This study examines the relative benefits (provisioning) and importance (regulating and cultural) of forest ecosystem services to households in the Chittagong Hill Tracts (CHT) region of Bangladesh. Our results from 300 household interviews in three rural locations stratified by wealth shows that wealth levels of the respondents play a key role in explaining variations in the perceptions and use of forest ecosystem services. Considering the direct benefits, the importance of provisioning ecosystem services (i.e. fuel wood, food, timber, bamboo, thatch grass and fodder) varies according to their relative use (i.e. subsistence and cash income) among households of different wealth groups. No significant difference was found in perceptions of indirect benefits of forest ecosystem services of water purification, regulating air quality, crop pollination, soil fertility, aesthetic and spiritual services. But the higher wealth groups perceived soil protection, soil fertility, pest and disease control as important for crop production as they have large landholdings for agricultural uses and tree cover. This study suggests local wealth conditions of the rural households characterise the demand of the use and perceived importance of forest ecosystem services. Differences in levels of wealth and ecosystem service provision imply careful consideration of social and economic factors in decision-making and making appropriate interventions for forest and tree management. The ecosystem services approach appears to be useful in capturing the broader diversity of benefits of forests and trees (i.e. material and non-material) as well as in supporting their integrated management at the landscape scale.

This study spatially estimated degraded lands in Indonesia that have limited functions for food production, carbon storage, and conservation of biodiversity and native vegetation and examined their suitability to grow biodiesel species (Calophyllum inophyllum, Pongamia pinnata, and Reutealis trisperma) and biomass species (Calliandra calothyrsus and Gliricidia sepium). Results showed ~3.5 million ha of degraded lands potentially suitable for these species in Indonesia. With the all-five-species scenario, these lands had the potential to produce 1105 PJ year-1 of biomass and 3 PJ year-1 of biodiesel. With the biodiesel-only-species scenario, these lands showed the potential to produce 10 PJ year-1 of biodiesel. Despite this energy potential, however, the land sizes were too small to support economies of scale for biofuel production. The study findings contribute to identifying lands with limited functions, modeling the growth of biofuel species on regional lands, and estimating carbon stocks of restored degraded lands in Indonesia.

The palm oil sector in Indonesia has seen the adoption of zero deforestation commitments by the larger companies in the form of various pledges around No Deforestation, No Peat, and No Exploitation (NDPE). At the same time, at the national and sub-national level, new governance arrangements are emerging for sustainability initiatives involving government, the private sector and other non-state actors. These initiatives have created new forms of governance relationships, most notably a shift in the types of function that were once the sole domain of the state. Some initiatives are independent and formulated outside of the state, but others interact with, and support, state actions. This paper explores the interactions between public and private sectors in the palm oil arena in Indonesia. It examines tensions and complementarities between these sectors, the degree to which, and manner in which, private standards are pushing the sustainability debate and implementation, and the likely outcomes in relation to their design.

The global palm oil value chain has grown in complexity; stakeholder relationships and linkages are increasingly shaped by new public and private standards that aim to ameliorate social and environmental costs while harnessing economic gains. Regulatory initiatives in the emerging policy regime complex struggle to resolve sector-wide structural performance issues: pervasive land conflicts, yield differences between companies and smallholders, and carbon emissions arising from deforestation and peatland conversion. Identifying opportunities for more effective governance of the palm oil value chain and supply landscapes, this paper explores disconnects, complementarities, and antagonisms between public regulations and private standards, looking at the global, national, and subnational policy domains shaping chain actors’ conduct. Greater complementarities have emerged among transnational instruments, but state regulation disconnects persist and antagonisms prevail between national state regulations and transnational private standards. Emerging experimental approaches, particularly at subnational level, aim to improve coordination to both enhance complementarities and resolve disconnects.

The Rejoso watershed provides vital livelihoods for the Pasuruan communities. Farming of annual and perennial crops, including agroforestry, timber plantations and livestock is the most dominant source of income. In the last decade, stone mining has gradually become an alternative source of income for the communities in the midstream area of the Rejoso Watershed. In the upper stream of Rejoso watershed, adjacent to Mount Bromo, the tourism becomes an alternative local revenue. Population growth and economic pressure are causing dramatic changes in the Rejoso Watershed. Dominant anthropocentric development activities have been gradually affecting the environment’s quality, especially the watershed’s function of maintaining good quality and quantity of water resources. The most common environmental issues related to water resources are floods, droughts, erosions, and landslides. An initiative that simultaneously conserves and strengthens the local economy and livelihoods is urgently needed. The ‘Rejoso Kita’ initiative was designed to achieve these aspirations. As an initial step towards the implementation of such an initiative, the World Agroforestry Centre (ICRAF) is leading a scoping study as basis for the ‘Rejoso Kita’ strategy implemented by a consortium coordinated by Social Investment Indonesia Foundation, CK-Net and partners supported by the Danone Ecosystem.

Cocoa is a food-industrial crop that can have an important role in poverty reduction for small producers in developing countries of Africa, Latin America, Asia and Oceania. The cocoa chocolate value chain moves every year millions of dollars that represent important dividends for producing countries and for national and international companies around the world. The International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) is a structural simulation model which allows for future analysis of cocoa market globally. The model has been developed at International Food Policy Research Institute (IFPRI) to consider the long term challenges facing policymakers in reducing hunger, and poverty in a sustainable fashion. IMPACT is the main quantitative tool used by the Global Futures & Strategic Foresight (GFSF) initiative, in which Bioversity International is involved as a partner. The aim of this report is to validate the performance and improve parameterization of IMPACT cocoa components. It focuses on ten largest cocoa producing countries in reviewing parameters related to yield growth rates. Based on historical cocoa yield time series forecasts are made using Autoregressive Integrated Moving Average (ARIMA). The forecast together with statistically estimated prediction intervals, supported by literature sources and expert knowledge are compared against respective yield trajectories embedded in IMPACT in order to make recommendations.

Based on 25 case studies from the global comparative study ‘GENNOVATE: Enabling gender equality in agricultural and environmental innovation’, this paper explores rural young women’s and men’s occupational aspirations and trajectories in India, Mali, Malawi, Morocco, Mexico, Nigeria, and the Philippines. We draw upon qualitative data from 50 sex-segregated focus groups with the youth to show that across the study’s regional contexts, young rural women and men predominantly aspire for formal blue and white-collar jobs. Yet, they experience an aspiration- achievement gap, as the promise of their education for securing the formal employment they seek is unfulfilled, and they continue to farm in their family’s production. Whereas some young men aspired to engage in knowledge-intensive or ‘modern’ agriculture, young women did not express any such interest. Framing our analysis within a relational approach, we contend that various gender norms that discriminate against women in agriculture dissuade young women from aspiring for agriculture-related occupation. We discuss the gendered opportunity spaces of the study sites, the meanings these hold for allowing young women and men to achieve their aspirations and catalyze agricultural innovation, and implications for agricultural policies and research for development. Our findings show that youth and gender issues are inextricably intertwined and cannot be understood in isolation one from the other.
