Examples of the effects of climate change on agriculture: 2019 flooding of the Toki River caused by Typhoon Hagibis, which was exacerbated by climate change; [1] increase in global leaf area primarily caused by the CO2 fertilization effect; [2] 2020–present Horn of Africa drought, the worst drought on record and made worse due to the effects ...
Example 1 The linear-reservoir model (or Nash model) is widely used for rainfall-runoff analysis. The model uses a cascade of linear reservoirs along with a constant first-order storage coefficient, K , to predict the outflow from each reservoir (which is then used as the input to the next in the series).
Due to an increase in heavy rainfall events, floods are likely to become more severe when they do occur. [59]: 1155 The interactions between rainfall and flooding are complex. There are some regions in which flooding is expected to become rarer. This depends on several factors. These include changes in rain and snowmelt, but also soil moisture.
Non-structural flood management includes land-use planning, advanced warning systems and flood insurance. Further examples are: "zoning ordinances and codes, flood forecasting, flood proofing, evacuation and channel clearing, flood fight activities, and upstream land treatment or management to control flood damages without physically ...
It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
Another is to restrict water to a certain area of a stream's natural bottom lands so that the bulk of such lands can be made available for agriculture. A third reason is flood control, with the idea of giving a stream a sufficiently large and deep channel so that flooding beyond those limits will be minimal or nonexistent, at least on a routine ...
On the Elbe River near Lenzen (Brandenburg), 420 hectares of floodplain were restored in order to prevent a recurrence of the Elbe floods of 2002. A total of 20 floodplain restoration projects on the Elbe River were envisaged after the 2002 floods, but only two have been implemented as of 2009 according to the environmental group de:BUND. [17]
Map of India based on survey of rivers of India.. The Indian rivers interlinking project is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking rivers using a network of reservoirs and canals to enhance irrigation and groundwater recharge and reduce persistent floods in some parts and water shortages in other parts of the country.
