Sustainable Futures

Sustainable Futures explores the links between population growth, diminishing resources and environmental challenges, and the implications for Australia's future. Written by leaders in their field, and based on presentations from the 2013 Fenner Conference on 'Population, Resources and Climate Change', this book is a timely insight into the intertwined challenges that we currently face, and what can be done to ensure a sustainable and viable future. The book identifies the major areas of concern for Australia's future, including environmental, social and economic implications of population growth; mineral and natural resources; food, land and water issues; climate change; and the obstacles and opportunities for action. Accessible, informative and authoritative, Sustainable Futures will be of interest to policy makers, students and professionals in the fields of sustainability and population growth.

This chapter examines the consequences of climate change from the point of view of disasters and their consequences for specific interest and population groups. A key focus is the social intersections that become apparent in such events. For example, the climatic and weather events that form the backdrop to present conflicts in places such as Syria are discussed, as are the gendered vulnerabilities evident in disaster situations such as cyclones and tsunami. Social conflicts stemming from climate change are then elaborated as a more general and increasingly likely scenario. In response to real and perceived threats and risk linked to climate change, issues of security are already generating angst among policy-makers and military planners. Indeed, the securitisation of natural resources, to the detriment of others, is emerging as an important climate-related issue, especially in regard to food, water, land, and air quality.

Climate change and disasters are fast emerging as the most significant challenges of the 21st century as global risks with impacts far beyond just the environment and implications on national security and development. As the world continues its contemporary patterns of production and consumption, the future is at immense risk. Climate Change has the potential to alter the ability of the earth’s physical and biological systems to provide goods and services essential for sustainable development. Today, a number of mainstream population and environment groups are claiming that population growth is a major cause of climate change and that lesser birth rates are the solution. If we cannot stabilize population, there is not an ecosystem on earth that we can save. If developing countries cannot stabilize their populations almost immediately, many of them face the disintegration of ecosystem. But in reality, even if we could today achieve zero population growth that would barely touch the climate problem — where we need to cut emissions by 50 to 80 percent by mid-century. Given existing income inequalities, it is inescapable that over consumption by the rich few is the key problem, rather than overpopulation of the poor many. In the absence of any commitment in the next two decades, their economies would become locked into a trajectory of elevated emissions and unsustainable development, while the cost of reversing the trend will become prohibitively high. This paper examines several outstanding issues on the interface between population and environment. Significantly, the study would come out with some policy recommendations to the policy makers.

As a result of rapid urbanisation, population growth, changes in lifestyle, pollution and the impacts of climate change, water provision has become a critical challenge for planners and policy-makers. In the wake of increasingly difficult water provision and drought, the notion that freshwater is a finite and vulnerable resource is increasingly being realised. Many city administrations around the world are struggling to provide water security for their residents to maintain lifestyle and economic growth. This chapter reviews the global challenge of providing freshwater to sustain lifestyles and economic growth, and the contributing challenges of climate change, urbanisation, population growth and problems in rainfall distribution. The chapter proceeds to evaluate major alternatives to current water sources such as conservation, recycling and reclamation, and desalination. Integrated water resource management is briefly looked at to explore its role in complementing water provision. A comparative study on alternative resources is undertaken to evaluate their strengths, weaknesses, opportunities and constraints, and the results are discussed.

The IPCC Report on Climate Change 2014 contains an enormous treasure trove of facts about natural science, mitigation, and potential impacts. However, the components of the report are sufficiently disconnected from each other, that it is not possible to reach policy insights into the merits of alternative mitigation or adaptation actions, where they should occur, when they should begin, and what policy tools are critical. Each Working Group has charged ahead with independent assumptions that obscure any possibility of an integrated assessment. The Report provides an authoritative collection of climate related materials but is organized so poorly that it provides very little insight into how to solve the climate problem. The Working Groups are not coordinated on a common mission to understand policy alternatives. The Reports consequently miss a great opportunity to organize science to inform policy makers of the way forward.

The urban development and management challenges of the developing world are well documented in the literature. However, the global built environment landscape is undergoing rapid changes. These changes are steeped in three fundamental imperatives, which have serious implications for the developing world. These imperatives are population growth and rising urbanisation; environmental challenges, particularly climate change and the quest to embrace sustainability as a panacea; and advances in technological development. This paper discusses these three imperatives with the view to teasing out their implications for urban development and management in the developing world. Consistent with the literature, the paper establishes that most of the population growth and rising urbanisation are occurring in the developing world, particularly Africa and Asia, and although these phenomena have the tendency to increase economic density and promote both private and public investment in urban development, especially construction/housing and related infrastructure activities, there are and will be several problems with them. These include land tenure insecurity, lack of access to decent affordable housing and the threat of destruction to heritage sites. Furthermore, environmental challenges such as poor waste management, and climate change are and will remain pressing issues requiring the adoption of sustainability credentials because of legislative requirements, moral suasion, and value addition. Despite the potential disruptive nature of technology with respect to some aspects of the built environment, it is recognised that advances in technology are essential to the achievement of optimal urban development and management outcomes in the developing world. The paper, therefore, recommends better understanding of the socio-economic, cultural, and political forces underlying urban growth in the developing world, factoring in technology and sustainability in urban development and management, and collaboration among relevant actors, particularly government and the private sector, for optimal outcomes.

The world is facing changes that have a significant impact on the environment and every aspect of human life. Currently, 588 million of the world's 7.8 billion people live in extreme poverty, 820 million people are starving, and 2.5 billion suffer from some form of micronutrient deficiency. The population is growing, the processes of aging and migration to urban settlements are actively underway, which is reflected in agricultural production and food demand. At the same time, the impact of the effects of climate change on the state of food security in the world is noteworthy. In addition, inequality, discrimination, and human rights abuses (including the right to adequate and safe human food) exacerbate these consequences, especially for small farms. According to the FAO, 33% of world population growth is expected in the near future. The population, from the existing 7.7 billion, will reach almost 10 billion by 2050. The population growth will lead to a strong increase in food demand. By 2050, it will be necessary to produce 70 percent more than 50-types foods, while the share of agriculture in global GDP is about 4%. While investments and innovations in the agricultural sector are increasing, the growth rate of yields is quite low. The rural population is declining and the aging process is actively underway, which has a serious impact on the labor force. Added to this is the fact that the current use of natural resources is irrational and under severe pressure. Twenty-five percent of agricultural land is severely degraded and land has long been recognized as a limited resource, while water resources are under heavy strain and there is a shortage of water in the world. Food losses and waste are an inefficient side of the sector and a strong threat to the environment. Up to 33% to 50% of the world produced food is never used for food, and the cost of these products exceeds $ 1 trillion. These trends have led to the problem of food shortages. As a result, poverty and hunger have intensified in the world. Moreover, there are four main factors that put pressure on the inherited model of agricultural production, without their solution the sector will not be able to cope with future demands. They are exacerbating the problem of hunger and food shortages in the world, putting pressure on agriculture and the ability of the sector to be able to meet future needs. These factors include: demographics, scarcity of natural resources, climate change, and food losses and waste. In Summary, overcoming these challenges requires the joint efforts of governments, investors, and innovative agricultural technologies to increase productivity and support the transition to an economy based on innovation and knowledge. Modern farms and enterprises have to work differently, mainly due to the use of technological advantages. In the future, agriculture must use sophisticated technologies and advanced equipment. Precision farming and the use of robotic systems ensure more profitable, efficient, safe and environmentally friendly agricultural production. According to the FAO report, these efforts require considerable resources: to eradicate hunger by 2030 and deal with the demographic pressures that will require an annual investment of $ 265 billion. Keywords: Agri-food sector, poverty, hunger, food security, food losses and waste.

Abstract Important water issues having environmental, social and economic consequences for the Canadian public will require federal leadership. Knowledge gaps often inhibit effective policy advice to various levels of government. Many emerging water issues are manifestations of larger global phenomena, such as climate change. Public policy concerns will likely require research into such topics as long-range hydrological forecasting, drought forecasting and the use of non-standard proxy data to extend hydrological records, and incorporation of hydrological information into econometric modelling. Toxic chemicals management will require more focussed research on pathways, fate and effects of contarinants within land-water systems, including important developments in ecotoxicology and knowledge of effects of chronic exposure of humans to toxins. Long-range planning in the north requires improvements in knowledge of arctic hydrology, aquatic ecology and toxic input. Climate change may place greater stress on groundwater resources. Knowledge of persistence and fate of toxins in groundwater is poor. It is not yet known whether toxic rain is a national concern. Large savings can be made in the pollution Control industry by operations research. Research into pollution control technologies has major economic implications for the Canadian environmental industry. Socio-economic research is needed into legal and social implications of alternative environmental ethics, of various forms of demand management, of risk assessment, and of means for dealing with uncertainty in public policy development. The interrelationship of research and water management, and of the nature of university involvement in the national effort must be reassessed. Greater focus of effort around issues of national concern will be necessary.

AbstractPhytoplankton are the unicellular photosynthetic microbes that form the base of aquatic ecosystems, and their responses to global change will impact everything from food web dynamics to global nutrient cycles. Some taxa respond to environmental change by increasing population growth rates in the short-term, and, based on this, are projected to increase in frequency over decades. To gain insight into how functional traits in these projected “climate change winners” change over different timescales, we evolved populations of microalgae in ameliorated environments for several hundred generations. While populations initially responded to environmental amelioration by increasing photosynthesis and population growth rates as expected, this response was not sustained. Instead, most populations evolved to allocate a smaller proportion of carbon to growth while increasing their ability to tolerate and metabolise reactive oxygen species (ROS). This diversion of fixed carbon from growth to catabolism underlies a quality-quantity tradeoff in daughter cell production which drives the evolution of population growth rates and of functional traits that underlie the ecological and biogeochemical roles of phytoplankton. There is intraspecific variation in the trait combinations that evolve, but all are consistent with mitigating ROS production and accumulation in ameliorated environments over hundreds of generations. This offers both an evolutionary and a metabolic framework for understanding how functional traits can change in primary producers projected to be “climate change winners”, and suggests that short-term population booms and associated trait shifts have the potential to be dampened or reversed if environmental amelioration persists.
