Drought risk assessment

Part 2 has contents biodiversity sector risks of temperature increase to biodiversity and ecosystems, climate change and the energy sector in Brazil, increased risk of drought in the semiarid lands of northeast Brazil due to regional warming above 4 °c, assessing the possible impacts of a 4 °c or higher warming in Amazonia.

In this study, the author assessed the risk of drought at Tien river estuary through two indices: Normalize Difference Vegetation Index (NDVI) and Standardized Precipitation Index (SPI) during the dry season months of 1991, 2001, 2010 and 2018. SPI values are interpolated to construct spatial modeling of meteorological drought levels.

With the development and widespread application of remote sensing technology and geographic information systems (GIS), the use of satellite images as well as GIS software is becoming more and more effective in monitoring, monitoring and assessing drought. In this study, the author assessed the risk of drought at Tien river estuary through two indices: Normalize Difference Vegetation Index (NDVI) and Standardized Precipitation Index (SPI) during the dry season months of 1991, 2001, 2010 and 2018.

The Temperature Vegetation Dryness Index (TVDI) with the combination of LST and NDVI index, was used as an indicator for drought risk assessment in Cu Chi District in 2005, 2010, 2015, and 2020. The results show a significant increase in dry areas between 2005- 2010 and 2015-2020. On the other hand, the results of the TVDI index and mapping drought of Cu Chi district on February 13, 2005, February 11, 2010, January 24, 2015 and February 23, 2020 are a basis for risk assessment and drought monitoring.

Currently, in the context of climate change, droughts, salinity intrusion, sea level rise etc. and through the reality, it can be seen that the structure of land use in Tra Vinh Province, Viet Nam has been impacted quite strongly. The salinity intrusion, flooding and drought have increased in recent years, requiring appropriately comprehensive and proactive solutions. First and foremost, it’s a solution to change the structure of land use in combination with the change of seed structure and crop production structure to ensure efficient and sustainable development.

This work aimed to assess the vulnerability to the climate change (CC) in Vinh Long province till 2020. Inundation, saltwater intrusion (SI), drought, riverbank landslide, storm, temperature and precipitation were taken into consideration. In addition to the socialogical investigation, risk assessment matrix, adaptive capacity assessment methods, etc. the vulnerability to CC was evaluated via index method.

The EU Water Framework Directive (2000/60/EC) is probably the most significant legislative instrument in the water field that was introduced on an international basis for many years. It moves towards integrated environmental management with key objectives to prevent any further deterioration of water bodies, and protect and enhance the status of aquatic ecosystems and associated wetlands. It aims to promote sustainable water consumption and will contribute to mitigating the effects of floods and droughts.

Improving water security can be achieved through increasing water supply, reducing water demand, as well as addressing water quantity and water quality issues related to broader water resource management. Current OECD work on water security is examining how best to manage risks and tradeoffs in the allocation of scarce water resources, in the allocation of pollution loads and in mitigating and preventing droughts and floods.

Information about climate1 is used to make decisions every day. From farmers deciding which crops to plant next season to mayors in large cities deciding how to prepare for future heat waves, and from an insurance company assessing future flood risks to a national security planner assessing future conflict risks from the impacts of drought, users of climate information span a vast array of sectors in both the public and private spheres. Each of these communities has different needs for climate data, with different time horizons (see Box 1) and different tolerances for uncertainty...

Agricultural biotechnology offers great promise for Africa and tissue culture and marker-assisted selection are already in widespread use across the continent. However, the safe application of these technologies requires functioning biosafety systems. The report focuses on the special issues related to biosafety in Africa.Crops can be improved by conventional breeding, by tissue culture and by marker-aided selection. But for many improvements - such as drought and salinity tolerance - GM technology is going to be essential.
