Book excerpt: Excerpt from Measuring the Effects of Weather on Agricultural Output: Procedures for Constructing Weather Indexes When we talk about weather in agriculture, we are interested in the net influence of all meteorological and closely associated factors on output. Weather and technol ogy, therefore, are defined in their broadest sense. Weather is those conditions Of the crop-growing environment that are beyond the control of farmers; technology is the sum total Of controllable resources and how they are used. Weather indexes for corn yields and production in Iowa from 1929 to 1960 were constructed using a plot data approach. State indexes were developed by aggregating weather indexes for individual Crop Reporting districts. The weather indexes were used in adjusting for the influence of weather the State and district actual yields per harvested acre and total production of corn. Variation in the adjusted yield series is an estimate of the effect of changes in technology. The series of adjusted corn yields for Iowa, 1929-60, indicates that improved technology increased yields in two steps. Yields from 1929 to 1935 were relatively stable. Beginning around 1935, corn yields increased rapidly until the early l94o's. This was the period marked by the rapid acceptance Of hybrid seed corn. Less than 1 percent of the corn acreage in 1933 was planted with hybrid seed; the percentage increased to nearly 99 by 1942. Corn yields remained at the new level throughout the l94o's and early l95o's. Then about 1954 a second period of yield increase began. This second increase does not appear to be due to any single factor but to a combina tion of improved practices such as increased use of fertilizer and higher planting rates.

Download or read book Agricultural Productivity and Producer Behavior written by Wolfram Schlenker and published by University of Chicago Press. This book was released on 2019-11-13 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural yields have increased steadily in the last half century, particularly since the Green Revolution. At the same time, inflation-adjusted agricultural commodity prices have been trending downward as increases in supply outpace the growth of demand. Recent severe weather events, biofuel mandates, and a switch toward a more meat-heavy diet in emerging economies have nevertheless boosted commodity prices. Whether this is a temporary jump or the beginning of a longer-term trend is an open question. Agricultural Productivity and Producer Behavior examines the factors contributing to the remarkably steady increase in global yields and assesses whether yield growth can continue. This research also considers whether agricultural productivity growth has been, and will be, associated with significant environmental externalities. Among the topics studied are genetically modified crops; changing climatic factors; farm production responses to government regulations including crop insurance, transport subsidies, and electricity subsidies for groundwater extraction; and the role of specific farm practices such as crop diversification, disease management, and water-saving methods. This research provides new evidence that technological as well as policy choices influence agricultural productivity.

This book was released on 1998-01-01 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the Ricardian approach (a cross sectional analysis of farm performance across different climate zones), this report examines the impact of climate change on the agriculture sector and the sector's adaptation to that change. Studies in the report measure the climate sensitivity of low-capital agriculture, test whether actual farm performance is as sensitive to climate as agronomic models predict, and compare the climate sensitivity of low-capital farms with the results already calibrated for U.S. agriculture. The goal of the study is to examine farm behavior and test whether there is any evidence that farmers in developing countries currently adjust to their local climates.

Available in PDF, EPUB and Kindle. Book excerpt: El Nino has been with us for centuries, but now we can forcast it, and thus can prepare far in advance for the extreme climatic events it brings. The emerging ability to forecast climate may be of tremendous value to humanity if we learn how to use the information well. How does society cope with seasonal-to-interannual climatic variations? How have climate forecasts been usedâ€"and how useful have they been? What kinds of forecast information are needed? Who is likely to benefit from forecasting skill? What are the benefits of better forecasting? This book reviews what we know about these and other questions and identifies research directions toward more useful seasonal-to-interannual climate forecasts. In approaching their recommendations, the panel explores: Vulnerability of human activities to climate. State of the science of climate forecasting. How societies coevolved with their climates and cope with variations in climate. How climate information should be disseminated to achieve the best response. How we can use forecasting to better manage the human consequences of climate change.

This book was released on 2018-06-13 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global temperatures have increased at an unprecedented pace in the past 40 years. This paper finds that increases in temperature have uneven macroeconomic effects, with adverse consequences concentrated in countries with hot climates, such as most low-income countries. In these countries, a rise in temperature lowers per capita output, in both the short and medium term, through a wide array of channels: reduced agricultural output, suppressed productivity of workers exposed to heat, slower investment, and poorer health. In an unmitigated climate change scenario, and under very conservative assumptions, model simulations suggest the projected rise in temperature would imply a loss of around 9 percent of output for a representative low-income country by 2100.

Available in PDF, EPUB and Kindle. Book excerpt: This paper quantifies the significance and magnitude of the effect of measurement error in remote sensing weather data in the analysis of smallholder agricultural productivity. The analysis leverages 17 rounds of nationally-representative, panel household survey data from six countries in Sub-Saharan Africa. These data are spatially linked with a range of geospatial weather data sources and related metrics. The paper provides systematic evidence on measurement error introduced by (1) different methods used to obfuscate the exact GPS coordinates of households, (2) different metrics used to quantify precipitation and temperature, and (3) different remote sensing measurement technologies. First, the analysis finds no discernible effect of measurement error introduced by different obfuscation methods. Second, it finds that simple weather metrics, such as total seasonal rainfall and mean daily temperature, outperform more complex metrics, such as deviations in rainfall from the long-run average or growing degree days, in a broad range of settings. Finally, the analysis finds substantial amounts of measurement error based on remote sensing products. In extreme cases, the data drawn from different remote sensing products result in opposite signs for coefficients on weather metrics, meaning that precipitation or temperature drawn from one product purportedly increases crop output while the same metrics drawn from a different product purportedly reduces crop output. The paper concludes with a set of six best practices for researchers looking to combine remote sensing weather data with socioeconomic survey data.

This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of Climate Change and Viarability on the Agricultural Production Systems provides an integrated assessment of global climate change's impact on agriculture at the farm level, in the context of farm level adaptation decisions. Ten agricultural areas in the Upper Midwest region - the heart of the United States' corn belt - were subjected to climate change and changing climate variability scenarios through simulations of future climate using results from general circulation models. Crop growth models, calibrated to the study sites, were used to simulate yields under varying climate conditions. Farm level production and economic analyses were performed to determine what adaptation strategies might be best utilized to maintain production and profitability for producers under conditions of global climate change and changing climate variability. Similar integrated analyses from Australia and Argentina provide comparisons from different regions.

Download or read book Investigating the impact of climate change on agricultural production in eastern and southern African countries written by Belloumi, Mounir and published by Intl Food Policy Res Inst. This book was released on with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been a significant issue since the end of the 20th century, and impacts a variety of economic sectors, primarily agriculture. The negative impacts of climate change on agricultural production are important because agriculture is closely linked to food security. Although they contribute the least to global pollution, it is estimated that African countries will be the most affected by climate variability. Our paper analyzes the impact of climate change on agricultural production in 11 Eastern and Southern African countries (ESA) during the period from 1961 to 2011 and estimates a panel data model for agricultural production using climate variables (e.g., annual precipitation and annual mean temperature) and economic factors (e.g., livelihood, fertilizer use, machinery, agricultural land, and labor) as explanatory variables.
