India ranks second in population after China and is projected that it will be first by 2050. With increasing population, food demand is also increasing, and to support this, agricultural production and imports should be improved. The Karnataka state in India ranks ninth for agricultural production. Many of the government programs are implemented in the state of Karnataka to improve agriculture. The soil type in the state also varies from majorly black soil in northern region and red soil in southern regions. The annual average rainfall in the northern and southern parts of Karnataka ranges between 800 and 1300 mm/year and coastal areas receiving highest on an average of 3000–4000 mm. The state is drained by five river basins, namely, Godavari, Krishna, Cauvery, Pennar, and West Flow rivers. The state is dependent on groundwater for its all-round development. There is a spurt in groundwater development since the 1990s. The current chapter focuses on the fact that in spite of the state being blessed by natural resources, government aids, and advisories, how challenging the improvement of agricultural efficiency can be? As an example to highlight the importance of sustainable agriculture, a case study from southern part of Karnataka in Berambadi village for 2014, 2015, and 2016 is shown. The farmer in this project applies irrigation in 2 years (2015 and 2016), but the lack of knowledge about crop water use and irrigation scheduling results in reduced water use efficiency. This study highlights that irrigation surely improves the agricultural productivity, but it also leads to loss of water if sustainable strategies are lacking.
