Greenhouse Gas (CO2 AND N2O) Emissions from Soils: A Review Chilean J. Agric. Res.
Muñoz,Cristina; Paulino,Leandro; Monreal,Carlos; Zagal,Erick.
In agricultural activities, the main greenhouse gases (GHG) are those related to C and N global cycles. The impact of agriculture on GHG emissions has become a key issue, especially when considering that natural C and N cycles are influenced by agricultural development. This review focuses on CO2 and N2O soil emissions in terrestrial ecosystems, with emphasis in Chilean and similar agro-ecosystems around the world. The influence of land use and crop management practices on CO2 and N2O emissions is analyzed; some mitigation measures to reduce such emissions are also discussed here. More knowledge on the biological processes that promote of GHG emissions from soil will allow creating opportunities for agricultural development under friendly-environmental...

Impact of global warming on Chinese wheat productivity AgEcon
You, Liangzhi; Rosegrant, Mark W.; Fang, Cheng; Wood, Stanley.
Climate change continues to have major impact on crop productivity all over the world. While many researchers have evaluated the possible impact of global warming on crop yields using mainly indirect crop simulation models, there are relatively few direct assessments on the impact of observed climate change on past crop yield and growth. We use a 1979-2000 Chinese crop-specific panel dataset to investigate the climate impact on Chinese wheat yield growth. We find that a 1 percent increase in wheat growing season temperature reduces wheat yields by about 0.3 percent. This negative impact is less severe than those reported in other regions. Rising temperature over the past two decades accounts for a 2.4 percent decline in wheat yields in China while the...

Impact of increasing mean air temperature on the development of rice and red rice. Repositório Alice
LAGO, I.; STRECK, N.A.; ALBERTO, C.M.; OLIVEIRA, F.B.; PAULA, G.M. de..
The objective of this study was to assess the development response of cultivated rice and red rice to different increases in minimum and maximum daily air temperatures, in Santa Maria, Rio Grande do Sul State, Brazil. One hundred years climate scenarios of temperatures 0, +1, +2, +3, +4, and +5oC, with symmetric and asymmetric increases in minimum and maximum daily air temperatures were created, using the LARS-WG Weather Generator, and a 1969?2003 database. Nine cultivated rice genotypes (IRGA 421, IRGA 416, IRGA 417, IRGA 420, BRS 7 TAIM, BR-IRGA 409, EPAGRI 109, EEA 406 and a hybrid), and two red rice biotypes (awned black hull-ABHRR, and awned yellow hull-AYHRR) were used. The dates of panicle differentiation (R1), anthesis (R4), and all grains with...

Impacto das mudanças climáticas no zoneamento de risco climático da mamona no Estado de Pernambuco. Repositório Alice
DIAS, N. D. H.; ASSAD, E. D..
A mamona é uma importante matéria-prima alternativa na produção de biodiesel. Entretanto ela pode ser afetada negativamente pelos efeitos das mudanças climáticas, reduzindo sua área de plantio em baixo risco. O objetivo desse trabalho foi quantificar esses impactos na produção da mamona, no Estado de Pernambuco, com base na tecnologia de Zoneamento Agrícola de Riscos Climáticos. Para tanto foram simulados os cenários agrícolas na produção da oleaginosa para os anos de 2010, representando o cenário atual, 2020, 2030 e 2040, utilizando-se as temperaturas obtidas pelo modelo HadRM3 do Hadley Centre. Neste estudo foram adotados os cenários A2 ? o mais pessimista que estima um aumento de temperatura entre 2ºC e 5,4ºC até 2100 e o B2, um pouco mais otimista, que...

Impacto das mudanças climáticas sobre a produção de cana-de-açúcar no Estado de Goiás. Repositório Alice
EVANGELISTA, B. A.; MARIN, F. R.; ZULLO JUNIOR, J..
A elevação do preço do petróleo, o apelo mundial pela redução das emissões de gases de efeito estufa e a produção de energia renovável viabilizaram o aumento da produção de álcool e criaram a necessidade de identificação de áreas de expansão do cultivo da cana-de-açúcar no Brasil. Por outro lado, o último relatório do IPCC apresenta informações conclusivas sobre ocorrências de alterações do clima e elevação das temperaturas. Neste sentido, estudos para identificar a vulnerabilidade dos sistemas agrícolas e quantificar o impacto das mudanças climáticas sobre as culturas agrícolas tornaram-se uma necessidade. O objetivo deste trabalho foi simular o efeito das mudanças climáticas sobre a produção de cana-de-açúcar, variedade RB72454, cultivada em três...

Implications of Expected Climate Change in the Eastern African Coastal Region: an Overview OceanDocs
Ogallo, L.J.; Alusa, A.L..
Anticipated global warming as a result of the emission of greenhouse gases into the atmosphere was the most important subject discussed during the fifteenth session of the Governing Council of UNEP and at the Second World Climate Conference. The so-called greenhouse effect is a most pressing environmental problem to the extent that it involves many scientific disciplines and hence presents major challenges. The greenhouse gases (CO2,' CFCs, CH4, N2O, O3, etc.) have the effect of changing the atmosphere's radiative balance by trapping more heat near the earth's surface resulting in a rise in global mean surface temperature. It is now clear that if the burning of fossil fuel continues at the present rate, global warming is a virtual certainty.

Long-term changes in rice development in Southern Brazil, during the last ten decades. Repositório Alice
STRECK, N. A.; UHLMANN, L. O.; GABRIEL, L. F..
The objective of this work was to test long‑term trends in the duration of rice development phases in Santa Maria, RS, Brazil. The duration from emergence to V3 (EM‑V3), emergence to panicle differentiation (EM‑R1), emergence to anthesis (EM‑R4), and emergence to all grains with brown hull (EM‑R9) was calculated using leaf appearance and developmental models for four rice cultivars (IRGA 421, IRGA 417, EPAGRI 109, and EEA 406), for the period from 1912 to 2011, considering three emergence dates (early, mid, and late). The trend of the time series was tested with the non‑parametric Mann‑Kendall test, and the magnitude of the trend was estimated with simple linear regression. Rice...

Long-term trends in fish recruitment in the north-east Atlantic related to climate change ArchiMer
Brunel, Thomas; Boucher, Jean.
This study investigates the temporal correspondence between the main patterns of recruitment variations among north-east Atlantic exploited fish populations and large-scale climate and temperature indices. It is of primary importance to know what changes in fish stock productivity can be expected in response to climate change, to design appropriate management strategies. The dominant patterns of recruitment variation were extracted using a standardized principal component analysis (PCA). The first principal component (PC) was a long-term decline, with a stepwise change occurring in 1987. A majority of Baltic Sea, North Sea, west of Scotland and Irish Sea populations, especially the gadoids, have followed this decreasing trend. On the contrary, some herring...

Maize leaf development under climate change scenarios. Repositório Alice
STRECK, N. A.; LANGNER, J. A.; LAGO, I..
Abstract ? The objective of this work was to simulate maize leaf development in climate change scenarios at Santa Maria, RS, Brazil, considering symmetric and asymmetric increases in air temperature. The model of Wang & Engel for leaf appearance rate (LAR), with genotype-specific coefficients for the maize variety BRS Missões, was used to simulate tip and expanded leaf accumulated number from emergence to flag leaf appearance and expansion, for nine emergence dates from August 15 to April 15. LAR model was run for each emergence date in 100-year climate scenarios: current climate, and +1, +2, +3, +4 and +5°C increase in mean air temperature, with symmetric and asymmetric increase in daily minimum and maximum air temperature. Maize crop failure due to...

Managing Global Climate Change An Executive Interview with David Lobell AgEcon
Jose, H. Douglas.
Many of the world’s poorest regions could face severe crop losses in the next two decades because of climate change, according to Dr. David Lobell, a Senior Research Scholar at Stanford University in the program on Food Security and Environment. The average world temperature is increasing slightly says Lobell and a one-degree Celsius increase over time greatly impacts climatic growing conditions. Unfortunately, agriculture is also the human enterprise most vulnerable to changes in climate. Understanding where these climate threats will be is central to our efforts in fighting hunger and poverty over the coming decades. Dr. Lobell outlines some of the challenges that lie ahead and steps researchers are taking to combat the issues. This interview was...

Mangrove increases resiliency of the French Guiana shrimp fishery facing global warming ArchiMer
Diop, Bassirou; Blanchard, Fabian; Sanz, Nicolas.
This paper deals with the biological, ecological and economic impact of global warming and mangrove habitat availability on the French Guiana shrimp fishery. A dynamic bio-economic model is built by employing a shrimp stock's growth function depending on Sea Surface Temperature (SST) and on mangrove surface. The model is empirically calibrated for the French Guiana shrimp fishery using time series collected over 1995–2011. First, two Cobb-Douglas functions, which describe shrimp's natural growth and harvest, are estimated. Then, a Maximum Economic Yield (MEY) harvest rule, based on the optimization of the net present value derived from fishing, is computed. Three management strategies are compared (Closure, Status Quo management, and MEY) under three...

MARKET-BASED SOLUTIONS TO ENVIRONMENTAL PROBLEMS: DISCUSSION AgEcon
Woodward, Richard T..
There is rapidly growing interest in the use of market-based (MB) instruments in environmental policy. The papers in this session discuss three relatively new areas for such policies: groundwater contamination, nonpoint source surface-water pollution and carbon sequestration. The papers point out the potential for MB policies in these areas, but significant challenges remain. This comment highlights challenges related to five issues: monitoring and enforcement, trading ratios, baselines, transaction costs, and risk and uncertainty. All these issues must be addressed before MB policies can take the full step from economic theory to regulatory reality.

MEASURING THE ECONOMIC EFFECT OF GLOBAL WARMING ON VITICULTURE USING AUCTION, RETAIL AND WHOLESALE PRICES AgEcon
Ashenfelter, Orley; Storchmann, Karl.
In this paper we measure the effect of year to year changes in the weather on wine prices and winery revenue in the Mosel Valley in Germany in order to determine the effect that climate change is likely to have on the income of wine growers. A novel aspect of our analysis is that we compare the estimates based on auction, retail, and wholesale prices. Although auction prices are based on actual transactions, they provide a thick market only for high quality, expensive wines and may overestimate climate’s effect on farmer revenues. Wholesale prices, on the other hand, do provide broad coverage of all wines sold and probably come closest to representing the revenues of farmers. Overall, we estimate a 1°C increase in temperature would yield an increase in...
