100-150 words) Remote sensing methods for locating and monitoring temporary ponds over large areas in arid lands were tested on a study site in Northern Senegal. Three main results are presented, validated with field data and intended to highlight different spectral, spatial and temporal characteristics of the methods: 1) Among several water indices tested, two Middle InfraRed-based indices (MN...

Construction of managed aquifer recharge structures (MARS) to store floodwater is a common strategy for storing depleted groundwater resources in arid and semi-arid regions, as part integrated water management (IWRM). MARS divert surface groundwater, but this can affect downstream fluvial processes. The impact on processes was investigated study by combining remote sensing techniques with hydro...

The arid region is spread over 38.7 million hectares mainly in the states of Rajasthan. Gujarat, Haryana, Punjab, Karnataka, Andhra Pradesh besides cold arid region situated in Leh, Laddakh and Himachal Pradesh. The region is marked by extreme environmental constraints due to which the cultivation of traditional crops is not economical. In a situation such as this, arid horticulture has ample s...
