Book Description
The agricultural sector is commonly regarded as one of the most vulnerable to climate change. Current understanding of the impact of climate change on this sector relies on the underlying assumptions about farmers' possible responses to weather variability, including changes in crop choice, input combinations and land management practices. Many previous analyses rely on the implicit (and restrictive) assumption that farmers operate under a fixed technology set across different states of nature. This assumption, represented through stochastic production or profit functions, is commonly made but seldom tested and may understate farmers' responses to climate change if state-contingent production technologies are, in reality, more flexible. The potential for farmers to adapt production technologies in response to unforeseen events is at the core of the state-contingent approach. Advanced in Chambers and Quiggin (2000), the theory contends that producers can manage uncertainty through the allocation of productive inputs to different states of nature. In this article, we test the assumption that farmers' observed behaviour is consistent with the state-contingent production theory using farm-level data from Australia. More precisely, we estimate the milk production technology for a sample of irrigated dairy farms from the southern Murray-Darling Basin over the period from 2006-2007 to 2009-2010.

Book Description
Agriculture is strongly affected by environmental factors, including variability in temperature and precipitation, which in turn shape the livelihoods farmers derive. In this context, the intensity of engagement in agriculture is directly influenced by temperature and rainfall patterns (ILO 2018). Both extreme weather shocks (that is, heat waves, droughts, and floods) and weather variability (that is, changes in temperature and rainfall patterns) can significantly disrupt participation in agriculture and related sectors, particularly when farmers’ capacity to cope with and adapt to these shocks is low. This policy note summarizes the results of a study designed to quantify the impact of climate variability and extreme weather shocks on the intensity of individuals’ participation in the agricultural sector in Africa, where intra-annual weather variability is high, and dependence on rainfed agriculture is significant. The study specifically focused on changes in the number of weekly hours worked in response to weather variability and climate extremes, and explored both the impact on women’s participation and their potential to mitigate the negative effects of these shocks.

Book Description
The state-contingent approach to production uncertainty presents a more general model than the conventional stochastic production approach. Here we investigate whether the state-contingent approach offers a tractable framework for representing climatic uncertainty at a farm level. We developed a discrete stochastic programming (DSP) model of a representative wheat-sheep (mixed) farm in the Central West of NSW. More explicit recognition of climatic states, and associated state-contingent responses, led to optimal farm plans that were more profitable on average and less prone to the effects of variations in climate than comparable farm plans based on the expected value framework. The solutions from the DSP model also appeared to more closely resemble farm land use than the equivalent expected value model using the same data. We conclude that there are benefits of adopting a state-contingent view of uncertainty, giving support to its more widespread application to other problems.

Book Description
Ethiopia is currently embroiled in a large-scale civil war that has continued for more than a year. Using unique High-Frequency Phone Survey (HFPS) data, which spans several months before and after the outbreak of the war, this paper provides fresh evidence on the ex durante impacts of the conflict on the food security and livelihood activities of affected households. We use difference-in-differences estimation to compare trends in the outcomes of interest across affected and unaffected regions (households) and before and after the outbreak of the civil war. Seven months into the conflict, we find that the outbreak of the civil war increased the probability of moderate to severe food insecurity by 38 percentage points. Using the Armed Conflict Location and Event Data (ACLED) on households’ exposure to violent conflict, we show that exposure to one additional battle leads to 1 percentage point increase in the probability of moderate to severe food insecurity. The conflict has reduced households’ access to food through supply chain disruptions while also curtailing non-farm livelihood activities. Non-farm and wage related activities were the most affected by the conflict while farming activities were relatively more resilient. Similarly, economic activities in urban areas were much more affected than those in rural areas. These substantial impact estimates, which are likely to be underestimates of the true average effects on the population, constitute novel evidence on the near-real-time impacts of an on-going civil conflict, providing direct evidence on how violent conflict disrupts the functioning of market supply chains and livelihoods activities. Our work highlights the potential of HFPS to monitor active and large-scale conflicts, especially in contexts where conventional data sources are not immediately available.

Book Description
The risks and opportunities of climate change for agriculture can be effectively dealt only by aligning policies, developing institutional capabilities, and investing in infrastructure and farms, as per the experiences of Albania, FYR Macedonia, Moldova, and Uzbekistan.

Book Description
Volume 3 of this series of the Handbooks in Economics follows on from the previous two volumes by focusing on the fundamental concepts of agricultural economics. The first part of the volume examines the developments in human resources and technology mastery. The second part follows on by considering the processes and impact of invention and innovation in this field. The effects of market forces are examined in the third part, and the volume concludes by analysing the economics of our changing natural resources, including the past effects of climate change.Overall this volume forms a comprehensive and accessible survey of the field of agricultural economics and is recommended reading for anyone with an interest, either academic or professional, in this area. *Part of the renown Handbooks in Economics series*Contributors are leaders of their areas*International in scope and comprehensive in coverage

Book Description
"This title was first published in 2003. Recent food shortages in Southern Africa, induced by rainfall variability but compounded by problems of governance and rising food prices, have resulted in massive relief efforts. A recent scientific innovation - supplying farmers with seasonal climate forecasts - has been touted as a way to increase preparedness for such situations. This book examines how climate forecasts are used by the agricultural community in Southern Africa. Based on a workshop funded by the World Bank, it covers a broad set of issues related to the use of seasonal forecasts, including factors that constrain users' capacities to respond. Case studies presented in the book explore how forecasts can potentially increase production and food security among a population highly dependent on agriculture and vulnerable to climate variability. The book reflects on how the production, delivery and uptake of seasonal forecasts might be improved, as well as the limitations to their usefulness, and it should catalyse future thinking and research in this field."--Provided by publisher.
