Technological development from horse-drawn carriages to the new Airbus A380 has led to a remarkable increase in both the capacity and speed of tourist travel. This development has an endogenous systemic cause and will continue to increase carbon dioxide emissions/energy consumption if left unchecked. Another stream of technological research and development aims at reducing pollution and will reduce emissions per passenger-kilometer, but suffers from several rebound effects. The final impact on energy consumption depends on the strength of the positive and negative feedback in the technology system of tourism transport. However, as the core tourism industry including tour operators, travel agencies, and, accommodation has a strong link with air transport, it is unlikely that technological development without strong social and political control will result in delivering the emission reductions required for avoiding dangerous climate change.

Purpose – The purpose of this research is to study the process conditions that give best yield and expected compositions of liquid smoke products that result during the pyrolisis process relying on predetermined variables.

Design/Methodology/Approach – Pyrolisis process running times are varied, that is, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, and 6 hourly. Condensing temperature maintained remained 25–30 °C. Products identification was applied by using gas chromotography mass spectroscopy.

Findings – Based on the research output, it was concluded that process conditions which give maximum yield were achieved when using double unit condenser (DUC) and time optional four hours, and it provides maximum volume liquid smoke product, and compositions of pyrolisis products. The process also created seven components, namely nepthalene, propanoic acid, 3,7 nanodiena, 2 metilguaiakol, 2-metoksi 4-methyl phenol, 4 ethyl-2 metoksil phenol, oxybanzene. Applying DUC during condensation phase may increase condensing force thereafter obtaining resulted products between 200% and 300% rather than using single unit condenser (SUC).

Research Limitations/Implications – This research was conducted on a fixed batch reactor made of a metal plate with a thickness of 3.0 mm. It carries 200 kg in capacity. In this phase, the moisture of candlenut shells might be kept in 10–12.5% wt. Process temperature applied ranged within 350–500 °C.

Originality/Value – In addition the study increased the theorical of understanding about pyrolisis process and Improving the production of liquid smoke from candlenut shell by pyrolisis process using the method of vapor condensation (Double unit condensor).

Purpose – This work aims to study the treatment of adsorbant on the increasing liquid hydrocarbon quality produced by pyrolysis low density polyethylene (LDPE) plastic waste at low temperature. The hydrocarbon distribution, physicochemical properties and emission test were also studied due to its application in internal combustion engine. This research uses pure Calcium carbonate (CaCO₃) and pure activated carbon as adsorbant, LDPE type clear plastic samples with control variable that is solar gas station.

Design/Methodology/Approach – LDPE plastic waste of 10 kg were vaporized in the thermal cracking batch reactor using LPG 12 kg as fuel at range temperature from 100 to 300°C and condensed into liquid hydrocarbon. Furthermore, this product was treated with the mixed CaCO₃ and activated carbon as adsorbants to decrease contaminant material.

Findings – GC-MS identified the presence of carbon chain in the range of C6–C44 with 24.24% of hydrocarbon compounds in the liquid. They are similar to diesel (C6–C14). The 30% of liquid yields were found at operating temperature of 300°C. The calorific value of liquid was 46.021 MJ/Kg. This value was 5.07% higher than diesel as control.

Originality/Value – Hydrocarbon compounds in liquid produced by thermal cracking at a low temperature was similar to liquid from a catalytic process.

The contemporary production, distribution, and consumption of food is today interconnected at the global level in the form of a global food chain, constituted by the relations between all the producers, distributors, and consumers of food in the World. A chain where the international trade law constitutes a conditioning element, which through the legal adoption of neoliberal ideals facilitates the strengthening of the agribusiness sector.

The present article aims to assess the environmental impact of the global food chain and engaging in the discussion of the adoption of more sustainable methodologies in the agriculture sector. By mobilizing the experience of participation in Civil Society Network for Food and Nutrition Security in the Community of Portuguese Speaking Countries (REDSAN-CCPL), we will critically expose the causal link of the activities of transnational corporations of the agribusiness sector with its environmental and public health impacts, particularly with cases in Global South countries (countries of the Community of Countries of Portuguese Language, CCPL).

At the end, and, following closely the current discussion at the United Nations level for the creation of a Declaration of the Rights of Peasants, and the creation, in 2017, of a legal regime for family farming under the CCPL, we will present a defense for the legal recognition of family farming at the international level, as a legal and political strategy to preclude the negative environmental impacts of the agribusiness sector.

Purpose – To examine the relationship between aviation and climate change, and the international dimensions of air transport.

Methodology/approach – A review of aviation's impacts on the global climate, mitigation strategies to reduce this impact, and the possible consequences of climate change for commercial aviation.

Findings – Although a range of mitigation measures have been developed and implemented to reduce aircraft emissions in the short term, with some environmental benefit, there is a real need for the aviation sector to identify the possible impacts of climate change on air travel operations, both to aircraft in flight and to operations at airports. A further challenge will be to devise adaptation plans that will address the vulnerabilities and thus ensure safe aviation-related operations.

Social implications – The climate change impacts of aviation will adversely affect society. In addition, some individuals may have to reduce or stop flying as a result of increased taxes and legislation implemented in response to climate change.

Originality/value of paper – There is a novel focus on the adaptation challenges for the aviation industry in response to climate change.

The chapter discusses two main themes: shifts in the global geography of aviation toward the developing world and several threats to the future growth of air transportation. The past two decades have witnessed a remarkable realignment of air passenger and air cargo traffic toward middle-income countries and the hubs within those countries.

The chapter documents these shifts, drawing on analyses of airline capacity around the world in 1998 and 2012. Given more rapid population and economic growth in Asia, the Middle East, Sub-Saharan Africa, and Latin America, further such developments seem likely. However, the chapter also reviews some of the principal challenges confronting aviation in its second century. These include the higher price of oil, the political challenges involved in building new airport infrastructure (especially in rich democracies), and efforts to limit the increase in greenhouse gas emissions and other air transportation externalities.

The chapter concludes that none of these challenges is very likely to reverse the long-term growth of air traffic but will instead intersect with the broader shift toward emerging markets to produce a still more complex geography of air services. The chapter further contends that the continued expansion of aviation will bring both daunting challenges to the world but also new opportunities to the low-income countries still marginalized in today’s airline networks.

To examine the role of new aeronautical technologies in improving commercial aviation’s environmental performance.

Reviews the environmental improvements that may be conferred through the adoption of alternative aviation fuels and new airframe, engine and navigation technologies.

Although aeronautical technologies have evolved considerably since the earliest days of powered flight, the aviation industry is now reaching a point of diminishing returns as growing global consumer demand for air transport outstrips incremental improvements in environmental efficiency. The chapter describes some of the technological interventions that are being pursued to improve aviation’s environmental performance and discusses the extent to which these innovations will help to deliver a more sustainable aviation industry.

Malnutrition is widespread and affects about one-third of humanity. Increasing production and consumption of vegetables is an obvious pathway to improve dietary diversity, nutrition and health. This chapter analyses how climate change is affecting vegetable production, with a special focus on the spread of insect pests and diseases. A thorough literature review was undertaken to assess current global vegetable production, the factors that affect the spread of diseases and insect pests, the implications caused by climate change, and how some of these constraints can be overcome. This study found that climate change combined with globalization, increased human mobility, and pathogen and vector evolution has increased the spread of invasive plant pathogens and other species with high fertility and dispersal. The ability to transfer genes from wild relatives into cultivated elite varieties accelerates the development of novel vegetable varieties. World Vegetable Center breeders have embarked on breeding for multiple disease resistance against a few important pathogens of global relevance and with large evolutionary potential, such as chili anthracnose and tomato bacterial wilt. The practical implications of this are that agronomic practices that enhance microbial diversity may suppress emerging plant pathogens through biological control. Grafting can effectively control soil-borne diseases and overcome abiotic stress. Biopesticides and natural enemies either alone or in combination can play a significant role in sustainable pathogen and insect pest management in vegetable production system. This chapter highlights the importance of integrated disease and pest management and the use of diverse production systems for enhanced resilience and sustainability of highly vulnerable, uniform cropping systems.

This chapter examines the involvement of finance companies in the purchasing and leasing of Australian farmlands. This is a new global phenomenon as, in past decades, finance companies have lent money to farmers, but have rarely sought to purchase land themselves. We investigate and discuss the activities of the Hancock company – an asset management firm that invested in farmland in northern NSW. Material on the activities of Hancock and other investment firms were obtained from documents on the public record, including newspaper reports. Semi-structured interviews with community members were conducted in the region of NSW where Hancock operated. Australian agriculture is being targeted for investment by companies in the finance industry – as part of a growing ‘financialization’ of farming. While it is financially beneficial for companies to invest, they do not do so in ‘empty spaces’ but in locations where people desire to live in a healthy environment. The Hancock company was criticized by community residents for failing to recognize the concerns of local people in pursuing its farming activities. To date, there have been few studies on the financialization of farming in Australia. By investigating the operations of the Hancock company we identify a number of concerns emerging, at the community level, about an overseas company running Australian-based farms.

While the need to respond to the wide-ranging challenges posed by climate change has been widely emphasized, there is still a relative lack of attention being given to the type, scale, and nature of responses that are taking place in different economic sectors and parts of the world. This chapter provides a review of the tourism-related responses to the implications of climate change in the context of New Zealand. This is a country where tourism is a very important sector of the economy that depends heavily on the credibility of its green and unspoilt destination image. However, due to its relative isolation in the South Pacific, New Zealand requires most international tourists to travel long distances, which results in considerable greenhouse gas emissions. The chapter outlines the private and public sectors' responses to these challenges with particular attention to their collaboration.
