Conceptual framework for the study of food waste generation and prevention in the hospitality sector.

Food waste has significant detrimental economic, environmental and social impacts. The magnitude and complexity of the global food waste problem has brought it to the forefront of the environmental agenda; however, there has been little research on the patterns and drivers of food waste generation, especially outside the household. This is partially due to weaknesses in the methodological approaches used to understand such a complex problem. This paper proposes a novel conceptual framework to identify and explain the patterns and drivers of food waste generation in the hospitality sector, with the aim of identifying food waste prevention measures. This conceptual framework integrates data collection and analysis methods from ethnography and grounded theory, complemented with concepts and tools from industrial ecology for the analysis of quantitative data. A case study of food waste generation at a hotel restaurant in Malaysia is used as an example to illustrate how this conceptual framework can be applied. The conceptual framework links the biophysical and economic flows of food provisioning and waste generation, with the social and cultural practices associated with food preparation and consumption. The case study demonstrates that food waste is intrinsically linked to the way we provision and consume food, the material and socio-cultural context of food consumption and food waste generation. Food provisioning, food consumption and food waste generation should be studied together in order to fully understand how, where and most importantly why food waste is generated. This understanding will then enable to draw detailed, case specific food waste prevention plans addressing the material and socio-economic aspects of food waste generation.

Landscapes in transition: an analysis of sustainable policy initiatives and emerging corporate commitments in the palm oil industry

Abstract The recent Southeast Asian haze crisis has generated intense public scrutiny over the rate, methods and types of landscape change in the tropics. Debate has centred on the environmental impacts of large-scale agricultural expansion, particularly the associated loss of high carbon stock forest and forests of high conservation value. Focusing on palm oil—a versatile food crop and source of bioenergy—this paper analyses national, international and corporate policy initiatives in order to clarify the current and future direction of oil palm expansion in Malaysia and Indonesia. The policies of ‘zero burn’, ‘no deforestation’ and ‘no planting on peatlands’ are given particular emphasis in the paper. The landscape implications of corporate commitments are analysed to determine the amount of land, land types and geographies that could be affected in the future. The paper concludes by identifying key questions related to the further study of sustainable land use policy and practice.

The economic case for low carbon waste management in rapidly growing cities in the developing world: The case of Palembang, Indonesia

The provision of appropriate waste management is not only an indicator of development but also of broader sustainability. This is particularly relevant to expanding cities in developing countries faced with rising waste generation and associated environmental health problems. Despite these urgent issues, city authorities often lack the evidence required to make well-informed decisions. This study evaluates the carbon and economic performance of low-carbon measures in the waste sector at a city level, within the context of a developing country. Palembang in Indonesia is used as a case of a medium-sized city in a newly industrialized country, with relevance to other similar cities in the developing world. Evidence suggests that the waste sector can achieve substantial carbon emission reductions, and become a carbon sink, in a cost effective way. Hence there is an economic case for a low carbon development path for Palembang, and possibly for other cities in developing and developed countries facing similar challenges.

Exploring the economic case for early investment in climate change mitigation in middle-income countries: a case study of Johor Bahru, Malaysia

The assumption that climate mitigation can only be afforded at a particular level of income is implicit in global climate negotiations. This suggests that middle-income countries may reach a tipping point in their development process where low-carbon investment becomes more viable. In order to avoid dangerous levels of climate change, this tipping point needs to be brought forward in time: upper-middle-income countries are already responsible for 37.8% of global CO2 emissions. We explore the scope for large-scale investment in climate mitigation in Johor Bahru, a fast-growing industrial city in Malaysia. We find that the city could reduce per capita emissions by 10.0% by 2025, relative to 2014 levels, through cost-effective investments. If the returns could be recovered and reinvested in low-carbon measures, Johor Bahru could reduce per capita emissions by 35.2% by 2025, relative to 2014 levels. This result suggests that the tipping point may be a function of political will and institutional capacity as well as income. This has substantial implications for global climate policy discussions, particularly the opportunities and responsibilities of middle-income countries. If comparable savings can be delivered across cities in middle-income countries, this would equate to a reduction in global emissions of 6.3% with the exploitation of cost-effective options and 11.3% with the exploitation of cost-neutral options. Investing in economically attractive low-carbon measures could also provide cities in middle-income countries with an opportunity to build the political momentum and institutional capacities necessary for deeper decarbonization.

Research agendas for the sustainable management of tropical peatland in Malaysia

There is a need for coordinated research for the sustainable management of tropical peatland. Malaysia has 6% of global tropical peat by area and peatlands there are subject to land use change at an unprecedented rate. This paper describes a stakeholder engagement exercise that identified 95 priority research questions for peatland in Malaysia, organized into nine themes. Analysis revealed the need for fundamental scientific research, with strong representation across the themes of environmental change, ecosystem services, and conversion, disturbance and degradation. Considerable uncertainty remains about Malaysias baseline conditions for peatland, including questions over total remaining area of peatland, water table depths, soil characteristics, hydrological function, biogeochemical processes and ecology. More applied and multidisciplinary studies involving researchers from the social sciences are required. The future sustainability of Malaysian peatland relies on coordinating research agendas via a ‘knowledge hub’ of researchers, strengthening the role of peatlands in land-use planning and development processes, stricter policy enforcement, and bridging the divide between national and provincial governance. Integration of the economic value of peatlands into existing planning regimes is also a stakeholder priority. Finally, current research needs to be better communicated for the benefit of the research community, for improved societal understanding and to inform policy processes.

Towards Sustainable Resource and Waste Management in Developing Countries: The Role of Commercial and Food Waste in Malaysia

Rising commercial waste generation poses a significant environmental and public health issue, especially in rapidly expanding urban centres in developing countries. A commercial district in Malaysia was selected to explore the challenges and opportunities for minimisation of commercial waste. This research provides empirical data on commercial and food waste generation rates, the problems faced by waste producers, and the priorities for improvement. It is argued that whilst commercial waste offers opportunities for waste minimisation, current challenges related to amenity and public health such as pests, odour and littering, can be addressed by the provision of additional bins, grease traps and improved public areas cleansing. The study concludes that food waste plays a key role in the progression towards a more sustainable waste management system in a developing country such as Malaysia, due to its high generation rates, its contribution to public health and amenity problems, and its high potential for resource recovery.

An investigation of the drivers, barriers, and incentives for environmental management systems in the Malaysian food and beverage industry

Food production and consumption is one of the major causes of global environmental degradation. One way to address environmental impacts in the food and beverage (F&B) sector is via the adoption of environmental management systems (EMS). To date, EMS research has focused predominantly on countries and sectors based in the Global North despite growing recognition of the global extent of environmental impacts from food production and consumption. In order to widen our knowledge of this topic in an under-researched emerging economy, this study examined factors determining EMS adoption within the Malaysian F&B industry. Drawn from a survey of 42 companies, this research investigated the drivers, barriers, and incentives to the adoption of the internationally recognized standard, ISO 14001. Discrepancies between the perceptions of small- and medium-sized enterprises and large companies’ as well as different product market groups were observed. It was found that large companies tend to have better understanding of the EMS concept and the enhancement of company image and improvement of environmental performance were the main drivers to implement EMS. High implementation costs and the lack of knowledge on the ISO 14001 standard were identified as the primary barriers to EMS adoption. Tax relief for certified companies and training and capacity building were considered as the most important incentives. Strategies were proposed to improve the environmental performance of Malaysian F&B companies which can strengthen the competitiveness of Malaysian F&B products in the global food market.
