Analysis inter decadal of climate variability facing projections of the CMIP5 models and its involvement in the agricultural production of Venezuela
Agriculture is the largest employer in the world and is probably the most dependent on the climate of all human activities. In recent years there have been events that have put in evidence the vulnerability of global food security to major meteorological phenomena, both in global agricultural markets and the world economy. The food price crisis and the subsequent economic crisis reduced the purchasing power of large segments of the population in many developing countries, which seriously reduced their access to food and thus undermined their food security. During the years 2009 and 2010 in Ven ...

Agriculture is the largest employer in the world and is probably the most dependent on the climate of all human activities. In recent years there have been events that have put in evidence the vulnerability of global food security to major meteorological phenomena, both in global agricultural markets and the world economy. The food price crisis and the subsequent economic crisis reduced the purchasing power of large segments of the population in many developing countries, which seriously reduced their access to food and thus undermined their food security. During the years 2009 and 2010 in Venezuela there were strong weather anomalies, drought in the first case and the second extreme rains, caused mainly by the effect of the El Niño-Southern Oscillation (ENSO) event, with warm phase (El Niño) in 2009 and cold phase (La Niña) in 2010, affecting farming, mostly in Monagas, Anzoátegui and Guárico States negatively influencing its economy. The planning of agricultural production based on the use of agricultural information, as calendars of sowing, as well as the monitoring of the conditions during the crop cycle and the use of agrometeorological forecasting, then is of great importance for the development of the agricultural sector, because it minimizes the effects on food production which might be affected by climate variability, making it less vulnerable. Model results confirm the importance of known key physiological processes, such as the shortening of the time to maturity of a crop with increasing mean temperature, decline in grain set when high temperatures occur during flowering, and increased water stress at high temperatures throughout the growing cycle. Temperature responses are generally well understood for temperatures up to the optimum temperature for crop development. The impacts of prolonged periods of temperatures beyond the optimum for development are not as well understood. For this study the agro meteorological stations selected have daily records of all climatic elements, so it held a summary monthly apart from daily data (with prior quality control) for the accumulated monthly rainfall and temperature maximum and minimum for the 1971-2010 series. Therefore, Inter decadal rainfall and temperature analysis and the use of the cropwat 8.0 to model future scenarios can be estimated water requirements of main crops, allowing some adaptation measures to help mitigate the effects of climate change in the country's agricultural production. In selected stations were determined significant changes on ETc when the temperature increase and the availability of water is a key factor to reach the harvest. Adaptation measurements involve reducing risk and vulnerability; for developing countries rely heavily on climate-dependent agriculture and especially in conjunction with poverty and rapid increase in population they are vulnerable to climate change.

Plaidoyer en faveur de la prévision hydrologique à échéance prolongée pour une meilleure gestion des ressources en eau
L’eau douce est une ressource importante pour la vie humaine, l’activité économique, la santé des écosystèmes et les processus géophysiques. Au cours de la première décennie du XXIe siècle, l’Australie a subi des épisodes de conditions météorologiques extrêmes et vécu, en 2013, l’année la plus chaude jamais observée depuis le début des relevés, en 1910. Les conditions hydrologiques en Australie comptent parmi les plus variables du monde. Le pays peut traverser de longues périodes de sécheresse comme la «sécheresse du millénaire» qui a frappé, entre 1997 et 2000, la plus grande partie de l’est ...

Cette variabilité a des incidences profondes sur la gestion des ressources en eau, et plus particulièrement sur la gestion des risques liés à l’approvisionnement en eau pour les villes, l’irrigation des cultures et la satisfaction des besoins environnementaux.

The Case for Extended Hydrologic Prediction Services for Improved Water Resource Management
Fresh water is important for human life, economic activity, ecosystem health and geophysical processes. Over the first decade of the twenty-first century, Australia weathered marked extremes, experiencing its warmest period, with 2013 marked as its warmest year since national records began in 1910. Hydrological conditions in Australia are among the most variable on Earth. Its streamflow regime can go through prolonged periods of droughts such as the “Millennium drought” that occurred between 1997 and 2000 across most parts of eastern Australia. This variability has a profound impact on the man ...

ESCWA Water Development Report, 5. Issues in sustainable water resources management and water services in the Arab region
The global community was proud to announce in 2012 that the global drinking water target articulated in the Millennium Development Goals had been met five years ahead of schedule. However, the countries of the water-scarce Arab region still face the continuing challenge of providing safe and sufficient water, and improved sanitation to its growing population. There is high variability in access to drinking water and sanitation services among Arab countries, with some countries nearly fully reliant on desalination, while others are not able to secure sufficient investments to meet basic needs.< ...

Grow in Concert with Nature: Sustaining East Asia’s Water Resources through Green Water Defense
This study will assess advances in management practices, institutional and technological innovations for managing water scarcity sustainably under a changing climate. The impetus for this analysis comes from the World Bank’s concept note ‘Towards Green Water Defense (GWD) in East Asia’ study, specifi cally one of the building blocks of the GWD concept: Managing water scarcity by “producing more with less” or increasing water productivity and reducing undesirable externalities.

A Framework for Financing Water Resources Management
OECD, 2012A lack of finance for water resources management is a primary concern for most OECD countries. This is exacerbated in the current fiscal environment of tight budgets and strong fiscal consolidation, as public funding provides the lion’s share of financial resources for water management.
The report provides a framework for policy discussions around financing water resources management that are taking place at local, basin, national, or transboundary levels. The report goes beyond the traditional focus on financing water supply and sanitation to examine the full range of water man ...

Water for wealth and food security: supporting farmer-driven investments in agricultural water management
IWMI, 2012This report addresses the effective use of available water as a way to help to improve productivity and reduce poverty in sub-Saharan Africa. It combines the practical improved water management systems and approaches, including the reduction of risks associated with climate variability through environmental risks monitoring. It documents the benefits of irrigation already been invested by farmers in small-scale irrigation, and provides practical recommendations and tools for governments, the private sector, donors and organizations to effectively support these farmer-led initiatives to improve ...

Technical Report Series, 01. Climate and Meteorological information requirements for water management : a review of issues
In providing better understanding between climate and water management, this review will, where relevant, adopt the approach of a SWOT analysis (strengths, weaknesses, opportunities and threats). As well as some recent initiatives noted in the preceding section, the basic data requirements and methods for water management are covered in the WMO Guide to Hydrological Practices (Ref. 7). In Volume I, Chapters 2, 3 and 4 deal with the climate observations required for water management, whilst Volume II deals with applications and management activities. Table II.4.1 from that publication is a part ...
