Abstract
ABSTRACT This article reports research from 2013 to 2016 with tribal smallholders, which evaluated technological interventions, aimed to diversify and intensify cropping systems and improve the climate resilience of the farming systems using modelling and participatory evaluation process. The options on providing access to irrigation water, strategic use of irrigation, and better crop husbandry practices were evaluated for their potential to impart climate resilience in farming systems. Irrigation trials revealed that, in the event of delayed rainfall, irrigation of 229-267 mm ensured timely transplanting and resulted in higher paddy yields (7.0 t ha−1). Supplemental irrigation during a mid-season dry spell increased paddy yield to from 0.64 to 6.1 t ha−1. Better vegetable cultivation practices viz. drip irrigation, polythene mulch, nursery raising in seedling trays and raised bed cultivation exhibited great potential to build climate resilience in the farming systems of the region. The study highlights the need for investments in small water harvesting structures and the promotion of alternative ways of cultivating and irrigating paddy during different climatic situations. The study suggests effective ways of engaging communities coupled with appropriate technological interventions to understand climate change and adaptation needs of the rice-fallow ecosystems in eastern India.
