Paragraphs

Stratospheric injection of sulphate aerosols has been advocated as an emergency geoengineering measure to tackle dangerous climate change, or as a stop-gap until atmospheric carbon dioxide levels are reduced. But it may not prove to be the game-changer that some imagine.

Paragraphs

• Adaptation should be defined strictly as actions that reduce climate change impacts.

• Many studies that claim to show adaptation benefits do not satisfy this definition.
• Three main causes of “adaptation illusions” are discussed.

A primary goal of studying climate change adaptation is to estimate the net impacts of climate change. Many potential changes in agricultural management and technology, including shifts in crop phenology and improved drought and heat tolerance, would help to improve crop productivity but do not necessarily represent true adaptations. Here the importance of retaining a strict definition of adaptation – as an action that reduces negative or enhances positive impacts of climate change – is discussed, as are common ways in which studies misinterpret the adaptation benefits of various changes. These “adaptation illusions” arise from a combination of faulty logic, model errors, and management assumptions that ignore the tendency for farmers to maximize profits for a given technology. More consistent treatment of adaptation is needed to better inform synthetic assessments of climate change impacts, and to more easily identify innovations in agriculture that are truly more effective in future climates than in current or past ones. Of course, some of the best innovations in agriculture in coming decades may have no adaptation benefits, and that makes them no less worthy of attention.

Paragraphs

Projecting the impacts of climate change on agriculture requires knowing or assuming how farmers will adapt. But empirical estimates of the effectiveness of this private adaptation are scarce and the sensitivity of impact assessments to adaptation assumptions is not well understood. Here we assess the potential effectiveness of private farmer adaptation in Europe by jointly estimating both short-run and long-run response functions using time-series and cross-sectional variation in subnational yield and profit data. The difference between the impacts of climate change projected using the short-run (limited adaptation) and long-run (substantial adaptation) response curves can be interpreted as the private adaptation potential. We find high adaptation potential for maize to future warming but large negative effects and only limited adaptation potential for wheat and barley. Overall, agricultural profits could increase slightly under climate change if farmers adapt but could decrease in many areas if there is no adaptation. Decomposing the variance in 2040 projected yields and farm profits using an ensemble of 13 climate model-runs, we find that the rate at which farmers will adapt to rising temperatures is an important source of uncertainty.

Paragraphs

A key question for climate change adaptation is whether existing cropping systems can become less sensitive to climate variations. We use a field-level dataset on maize and soybean yields in the central United States for 1995 through 2012 to examine changes in drought sensitivity. Although yields have increased in absolute value under all levels of stress for both crops, the sensitivity of maize yields to drought stress associated with high vapor pressure deficits has increased. The greater sensitivity has occurred despite cultivar improvements and increased CO2, and reflects the agronomic trend toward higher sowing densities. The results suggest that agronomic changes tend to translate improved drought tolerance of plants to higher average yields, but not to decreasing drought sensitivity of yields at the field scale.

Meeting the world’s need for food in the 21st century presents unprecedented challenges and opportunities. The global population is expected to grow toward 9 billion by 2050, and more families will live in middle-income countries and urban areas with expanding per capita consumption. At the same time, climate change and resource constraints will likely reduce crop and animal production in many locations, potentially creating greater disparities in incomes, food access, and nutrition around the world. Roz Naylor, a thought leader in global food security, will discuss the world’s future food dilemma and present a range of solutions focused on the diversification of food systems, improved input efficiencies, renewable energy use, new crop technologies, and policy adjustments. Her talk will demonstrate how food security, in its broadest form, is tied to security of many other kinds: energy, water, climate, health, the environment, and national security.

FSE director Roz Naylor’s research focuses on economic and biophysical dimensions of food security and environmental impacts of crop and animal production. Her extensive field research and published work span issues related to intensive crop production, aquaculture and livestock systems, biofuels, climate change, food price volatility, and food policy analysis. At Stanford, Naylor teaches courses on the world food economy, humanenvironment interactions, and sustainable agriculture.

Naylor's new book The Evolving Sphere of Food Security (Oxford University Press, September) brings together 19 Stanford scholars from across campus to explore the many faces and facets of global food security. Copies of the book will be available for purchase at the event.

The annual Earth Matters lecture series is jointly sponsored by Stanford Continuing Studies and the Stanford School of Earth Sciences.

Paragraphs

Feeding a growing global population in a changing climate presents a significant challenge to society. The projected yields of crops under a range of agricultural and climatic scenarios are needed to assess food security prospects. Previous meta-analyses have summarized climate change impacts and adaptive potential as a function of temperature, but have not examined uncertainty, the timing of impacts, or the quantitative effectiveness of adaptation. Here we develop a new data set of more than 1,700 published simulations to evaluate yield impacts of climate change and adaptation. Without adaptation, losses in aggregate production are expected for wheat, rice and maize in both temperate and tropical regions by 2 degrees Celsius of local warming. Crop-level adaptations increase simulated yields by an average of 7-15%, with adaptations more effective for wheat and rice than maize. Yield losses are greater in magnitude for the second half of the century than for the first. Consensus on yield decreases in the second half of the century is stronger in tropical than temperate regions, yet even moderate warming may reduce temperate crop yields in many locations. Although less is known about interannual variability than mean yields, the available data indicate that increases in yield variability are likely.

Mr. Rudd served as Australia’s 26th Prime Minister from 2007 to 2010, then as Foreign Minister from 2010 to 2012, before returning to the Prime Ministership in 2013. As Prime Minister, Mr. Rudd led Australia’s response during the Global Financial Crisis. Australia's fiscal response to the crisis was reviewed by the IMF as the most effective stimulus strategy of all member states. Australia was the only major advanced economy not to go into recession. Mr. Rudd is also internationally recognized as one of the founders of the G20 which drove the global response to the crisis, and which in 2009 helped prevent the crisis from spiraling into a second global depression.

As Prime Minister and Foreign Minister, Mr. Rudd was active in global and regional foreign policy leadership. He was a driving force in expanding the East Asia Summit to include both the US and Russia in 2010. He also initiated the concept of transforming the EAS into a wider Asia Pacific Community to help manage deep-routed tensions in Asia by building over time the institutions and culture of common security in Asia. On climate change, Mr. Rudd ratified the Kyoto Protocol in 2007 and legislated in 2008 for a 20% mandatory renewable energy target for Australia. Mr. Rudd launched Australia's challenge in the International Court of Justice with the object of stopping Japanese whaling in the Southern Ocean. Mr Rudd drove Australia’s successful bid for its current non-permanent seat on the United Nation’s Security Council and the near doubling of Australia's foreign aid budget.

Mr. Rudd remains engaged in a range of international challenges including global economic management, the rise of China, climate change and sustainable development. He is on the International Advisory Panel of Chatham House. He is a proficient speaker of Mandarin Chinese, a Visiting Professor at Tsinghua University and funded the establishment of the Australian Centre on China in the World at the Australian National University. He was a co-author of the recent report of the UN Secretary General's High Level Panel on Global Sustainability – “Resilient People, Resilient Planet" and chairs the World Economic Forum's Global Agenda Council on Fragile States. He also remains actively engaged in indigenous reconciliation.
