Many Indian capitals are rapidly becoming megacities due to industrialization and rural–urban emigration. Land use within city boundaries has changed dynamically, accommodating development while replacing traditional land-use patterns. Using Landsat-8 and IRS-P6 data, this study investigated land...


Gumma, Murali K.Irshad, M.Nedumaran, S.Whitbread, Anthony M.Lagerkvist, C.J.[Urban Sprawl and Adverse Impacts on Agricultural Land: A Case Study on Hyderabad, India]Urban Sprawl and Adverse Impacts on Agricultural Land: A Case Study on Hyderabad, India

Net irrigated area in the Krishna river basin is varying quiet frequently due to water scarcity. Accurate area and extent of irrigated area in the Krishna River Basin is not available. State Irrigation Department projects large area under irrigation in the Krishna River Basin, which is attributed...


Gumma, Murali K.Thenkabail, Prasad S.Gautam, N.C.Gangadhara Rao, ParthasaradhiManohar, Velpuri[Irrigated area mapping using AVHRR, MODIS and LANDSAT ETM+ data for the Krishna River Basin, India]Irrigated area mapping using AVHRR, MODIS and LANDSAT ETM+ data for the Krishna River Basin, India

The objective of this study was to investigate the changes in cropland areas as a result of water availability using Moderate Resolution Imaging Spectroradiometer (MODIS) 250 m time-series data and spectral matching techniques (SMTs). The study was conducted in the Krishna River basin in India, a...

A lack of accuracy, uniqueness and the absence of systematic classification of cropland categories, together with long-pending updates of cropland mapping, are the primary challenges that need to be addressed in developing high-resolution cropland maps for south Asia. In this review, we analyzed ...


Patil, P.Gumma, Murali K.[A Review of the Available Land Cover and Cropland Maps for South Asia]A Review of the Available Land Cover and Cropland Maps for South Asia

Impact of dynamic land use and land cover changes on the livelihood of local communities and ecosystem services is a major concern. This is particularly evident in most dryland agricultural systems in South Asia. We study land use/land cover (LULC) changes over the last two decades in a watershed...


Ahmed, I.M.Gumma, Murali K.Kumar, S.Craufurd, Peter Q.Rafi, I.M.Haileslassie, Amare[Land use and agricultural change dynamics in SAT watersheds of southern India]Land use and agricultural change dynamics in SAT watersheds of southern India

Interannual variation in rainfall throughout Tamil Nadu has been causing frequent and noticeable land use changes despite the rapid development in groundwater irrigation. Identifying periodically water-stressed areas is the first and crucial step to minimizing negative effects on crop production....


Gumma, Murali K.Kajisa, K.Mohammed, I.A.Whitbread, Anthony M.Nelson, A.Rala, A.Kuppannan, Palanisami[Temporal change in land use by irrigation source in Tamil Nadu and management implications]Temporal change in land use by irrigation source in Tamil Nadu and management implications

Soil and water conservation (SWC) practices like that of erosion control and soil fertility measures were commonly practiced in the semiarid region of southern Mali since the 1980s. The SWC practices were mainly meant to increase water availability in the subsurface, reduce farm water runoff and ...

The automation of agricultural mapping using satellite-derived remotely sensed data remains a challenge in Africa because of the heterogeneous and fragmental landscape, complex crop cycles, and limited access to local knowledge. Currently, consistent, continent-wide routine cropland mapping of Af...
