Evolution of upper layer temperature in the Bay of Biscay during the last 40 years
Provedor de dados: 5
Autores: Michel, Sylvain; Vandermeirsch, Frederic; Lorance, Pascal.
The temperature evolution over the past 40 years in the Bay of Biscay (North-East Atlantic) is investigated from an in situ data analysis, completed with a satellite SST (Sea Surface Temperature) analysis over the last 20 years. The in situ dataset is an interannual version of the BoByClim climatology, covering the Bay of Biscay area with a 10-km horizontal resolution and a 5-m vertical step. The satellite dataset is the European COastral Sea Operational Observing and Forcast System Program (ECOOP) daily analysis, covering the IBIROOS (Iberian-Biscay-Irish Sea) area with a 4-km resolution. The study area (43 degrees N-50 degrees N/12 degrees W-1 degrees W) extends over the intersection of the domains covered by these two analyses. In the 0-200 m layer of...

Analysis and prediction of the fluctuation of sardine abundance using a neural network
Provedor de dados: 5
Autores: Aoki, I; Komatsu, T.
This paper examines the use of a neural network to analyse and predict the winter catch, in the Joban-Boso Seas off the Pacific coast of central Japan, of young Japanese sardine (Sardinops melanostictus) representing the index of recruits in the sardine stock. The supervised learning paradigm, a three-layer network and a back-propagation algorithm were employed in constructing the neural net. A number of biological, hydrographic and climatic factors constituted an input vector, the output being the catch of young sardine. The association of sardine abundance with environmental factors was quantified in the form of the trained neural network, which indicated important associations with the Southern Oscillation Index, with patterns of the Kuroshio and the...

Autores: Sierro, Fj; Hodell, Da; Curtis, Jh; Flores, Ja; Reguera, I; Colmenero-hidalgo, E; Barcena, Ma; Grimalt, Jo; Cacho, I; Frigola, J; Canals, M.
Down-core samples of planktonic and benthic foraminifera were analyzed for oxygen and carbon isotopes in International Marine Past Global Changes Study (IMAGES) core MD99-2343 in order to study the interactions between climate change in the Northern Hemisphere and the western Mediterranean thermohaline circulation at times of Heinrich events (HE). Our results confirm the antiphase correlation between enhanced North Atlantic Deep Water formation and low ventilation in the Mediterranean. However, this study reveals that this antiphase relationship in deepwater formation between the North Atlantic and Mediterranean was interrupted during times of HE when the injection of large volumes of water from melting icebergs reached the entrance to the Mediterranean....

How temperate forests will respond to climate change is uncertain; projections range from severe decline to increased growth. We conducted field tests of sessile oak (Quercus petraea), a widespread keystone European forest tree species, including more than 150,000 trees sourced from 116 geographically diverse populations. The tests were planted on 23 field sites in six European countries, in order to expose them to a wide range of climates, including sites reflecting future warmer and drier climates. By assessing tree height and survival, our objectives were twofold: (1) to identify the source of differential population responses to climate (genetic differentiation due to past divergent climatic selection versus plastic responses to ongoing climate...

Effect of environmental conditions on the seasonal and inter-annual variability of small pelagic fish abundance off North-West Africa: The case of both Senegalese sardinella
Provedor de dados: 5
Autores: Thiaw, Modou; Auger, Pierre-amael; Ngom, Fambaye; Brochier, Timothee; Faye, Saliou; Diankha, Ousmane; Brehmer, Patrice.
The objective of this study was to assess the effect of environmental variations on the abundance of Sardinella aurita and Sardinella maderensis in Senegalese waters in the upwelling system. Monthly data indicating the abundance of sardinella were first estimated from commercial statistics, using Generalized Linear Model from 1966 to 2011. Abundance indices (AIs) were then compared with environmental indices, at the local scale, a Coastal Upwelling Index (CUI) and a coastal Sea Surface Temperature (SST) index, and on a large scale, the North Atlantic Oscillation (NAO), the Atlantic Multidecadal Oscillation (AMO) and the Multivariate El Nino Southern Oscillation Index (MEI), using correlations and times series analyses. The results showed that the abundance...

Temperature variability in the Bay of Biscay during the past 40 years, from an in situ analysis and a 3D global simulation
Provedor de dados: 5
Autores: Michel, Sylvain; Treguier, Anne-marie; Vandermeirsch, Frederic.
A global in situ analysis and a global ocean simulation are used jointly to study interannual to decadal variability of temperature in the Bay of Biscay, from 1965 to 2003. A strong cooling is obtained at all depths until the mid-1970's, followed by a sustained warming over similar to 30 years. Strong interannual fluctuations are superimposed on this slow evolution. The fluctuations are intensified at the surface and are weakest at similar to 500 m. A good agreement is found between the observed and simulated temperatures, in terms of mean values, interannual variability and time correlations. Only the decadal trend is significantly underestimated in the simulation. A comparison to satellite sea surface temperature (SST) data over the last 20 years is also...

Vulnerability of Water Resources to Environmental Change in Southern Africa. A report for the Pan African START Secretariat and UNEP.
Provedor de dados: 20
Autores: Beekman, H.E.; Saayman, I.; Hughes, S.
The availability and access to water strongly influences patterns of economic growth and social development (Alan, 2002). In this regard, the Southern African region faces considerable challenges in meeting the social and economic needs of its populations (Hirji et al., 2002). It has become increasingly important that water resource development takes place in the context of integrated water resource management (IWRM) with its main principles of equity (regarding access), efficiency (economic) and sustainability (environment).

Provedor de dados: 190
Autores: Morais, Vinícius Augusto; Silva, Carlos Alberto; Scolforo, José Roberto Soares; Mello, José Márcio; Araújo, Emanuel José Gomes de; Assis, Edson Aquiles de.
The total soil organic carbon (C) is regulated by climatic factors, altitude, texture and soil depth. Due to higher storage in surface, it is common to observe the exponential model to adjust the C content in the soil profile. This study was carried out in order to study the influence of climatic factors, altitude and soil depth on the vertical distribution (0-100 cm) of C in five Cerrado fragments located in the municipalities of Januária and Bonito de Minas, Minas Gerais State, Brazil. Soil samples were collected in the following layers: 0-10, 10-20, 20-40, 40-60 and 60-100 cm. The maximum and minimum levels of C varied depending on the sampling site, fragment and soil layer sampled. Larger variations in the levels of C were noted for the 0-10 cm layer,...

Alternative Hedging Strategies in Maize Production to Cope with Climate Variability and Change
Provedor de dados: 31
Autores: Fuhrer,   Jurg; Beniston,   Martin; Calanca,   Pierluigi; Torriani,   Daniele Simone.
Climate change with increasing climate variability is likely to alter risks in agricultural production. The effectiveness of using weather derivatives to hedge against drought risks for rain-fed grain maize production was investigated for current (1981-2003) and future (2070- 2100) climates in Switzerland. The climate change scenario was extrapolated from results of a regional climate model (HIRHAM4) based on the IPCC A2 emission scenario. In addition, a sensitivity analysis was performed by varying the mean and variance of the initial probability space for the seasonal precipitation sum. Profits and risks with and without hedging were compared using the analogy of the value-at-risk measure (VaR), i.e., a quantile-based measure of risk. A Monte Carlo chain...

Provedor de dados: 31
Autores: Suwanabatr,   Bhibhatra; Mekhora,   Thamrong.
This study focused on the impacts on vulnerable areas in five provinces and five regions in Thailand. The findings indicated that events caused by El Nino induced weather changes had some impacts on the stabilization of upland agriculture in those vulnerable areas. Broadly speaking, severe drought and a long period of water shortages were experienced by some of the vulnerable areas in Northeast and Central Thailand. Some areas experienced a decrease of corn yield while others experienced complete failure of field corn, sorghum, sugarcane, peanut and mungbean. The impacts of El Nino on the social and economic conditions of Thailand's vulnerable areas were an occurrence of labour mobilization, and weaknesses in purchasing power and loan repayment abilities...

Coping Strategies Against El Nino: The Case of Selected Communities in Talugtug, Nueva Ecija, Philippines
Provedor de dados: 31
Autores: Monsalud,   Florentino C.; Montesur,   Jaime G.; Abucay,   Edwin R.
The occurrence of El Nino causes tremendous havoc to economies. Recognizing this problem, the Philippine government has been introducing measures to mitigate the impact of the El Nino phenomenon. One of the measures to lessen the vulnerability of the farmers on El Nino related risk is the Small Water Impounding Projects (SWIPs). Furthermore, farmers have their own initiatives and coping mechanisms to mitigate the effects of El Nino. This research was undertaken to document the coping mechanisms, which would be useful in policy formulation. This study aims to: a) Determine the impacts of El Nino-related abnormal weather changes on agricultural production and farmers' income; b) Document the existing farming systems, resources, infrastructure, institutions,...

Autores: Mekhora,   Thamrong.
This second phase of the study is expected to produce actual and accurate information concerning socio-economic information and measures to cope with the El Nino effects at the farm level. Evidence of abnormal weather was apparent in Thailand in 2001 when the rain was less than the previous years' and the high temperatures were from January to March 2002. However, the rain came early in May 2002. Thus, the period of 2001 is suitable to represent an abnormal year for the study of the second phase of the project. The objectives of the second phase are to analyze and evaluate drought impacts at farm-household level, farmer's responses and government measures to overcome the problems. The research was conducted in two different provinces, namely Lop Buri in...

Stabilization of Upland Agriculture under El Nino Induced Climatic Risk: Impact Assessment and Mitigation Measures in Malaysia
Provedor de dados: 31
Autores: Tawang,   Ariffin bin; Tengku Ahmad,   Tengku Ariff bin; Abdullah,   Mohd. Yusof bin.
During the last twenty years, the incidence of abnormal weather variation has increased, mainly due to El Nino. In Malaysia, the El Nino induced weather change has resulted in prolonged dry seasons, which have led to severe drought and increased temperatures. This has been further compounded by the formation of haze due to the large scale burning of forest and plantations for land preparation. These phenomena brought serious implications for farm productivity and land use patterns. This report describes, analyzes and quantifies the impact of El Nino induced climate variability on the agricultural sector and the rural economy. It also proposes measures to mitigate the damage and to stabilize agricultural production for the welfare of the rural population at...

Autores: Iglesias,   Ana; Quiroga,   Sonia; Diz,   Agustin; Garrote,   Luis.
We evaluate the potential impacts and measure the potential limits of adaptation of agriculture to climate change. Pressures on land and water resources are expected to intensify existing risks in low latitude areas – e.g., South-East Asia deltas – and in regions with current water scarcity – e.g. Mediterranean, and create new opportunities in some northern temperate areas – e.g., Northern Russia, Northern Europe. The need to respond to these risks and opportunities is addressed by evaluating the costs and benefits of a number of technical and policy actions. The discussion aims to assist stakeholders facing the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

In 1997, a drought associated with a severe ENSO (El Nino-Southern Oscillation) event was the cause of significant disruptions to village food and water supplies in PNG, as well as the failure of the water supply to towns and smaller service centres, mine closures and disruption to the supply of electricity. There were severe shortages of food and water, with garden produce declining by 80 per cent. Up to 40 per cent of the rural population (1.2 million people) were without locally available food by the end of 1997. The health of rural people declined and in many isolated places the mortality rate increased. Many thousands of people migrated to towns and cities to live with wage-earning relatives.

The El Nino events of 1982 and 1997 are the biggest ones in history. Both El Nino events resulted in decreased rainfall, particularly during the dry season of May-August. The 1997 El Nino caused a higher decrease in rainfall than the 1982 one. Consistently, in Java and Sulawesi the decrease in rainfall was higher compared to the national average in both 1997 and 1982. Since Java and South Sulawesi are major food producers (about 65 per cent of national food crop production), El Nino events could disturb national food security. In Kalimantan, the decrease in rainfall was relatively high during the 1997 El Nino, but quite low during 1982. On the contrary, Sumatera, Bali and Nusa Tenggara experienced a decrease in rainfall which was quite high in 1982 but...

Wheat Facts and Futures 2009
Provedor de dados: 31
For nearly half a century, the international wheat breeding system has delivered improved high yielding varieties of wheat that created (along with rice) the Green Revolution and underpinned strong growth in wheat productivity in irrigated and rainfed, developed and underdeveloped, regions. Future priorities for breeding and complementary sciences will still include yield but will also diversify in response to changing market demands and growing environments, particulary in developing countries. It is argued that in the coming decades research on wheat quality characteristics will become increasingly important to plant breeders, whose work will be supported by the development of markers and advanced tools from molecular biology. Breeders will have to...

E.A. Moya-Elizondo. 2013. Fusarium crown rot disease: biology, interactions, management and function as a possible sensor of global climate change. Cien. Inv. Agr. 40(2):235-252. Wheat crops are commonly affected by the dryland root rot complex (DLRRC) under dry and semiarid conditions. This complex is associated with seedling blight, and rotting of roots, crowns and stems of wheat plants. Several pathogens are associated with this complex, but Fusarium crown rot disease (FCR) is the most common and is of worldwide importance. Increased drought frequency and changes in rainfall regimes associated with global climate change may increase the prevalence of this complex of diseases, especially of FCR, in wheat crop areas. This review discusses the...
