  • Adaptation to climate change and variability: A case of direct seeded rice in Andhra Pradesh, India

    Journal of Water and Climate Change, 2019
    Farmers, researchers and policy-makers are increasingly concerned about the potential impacts of climate change. Researchers are using various climate models to assess the impacts and identifying relevant alternative adaptation strategies to mitigate climate change. In India, rice is the major cereal crop grown and is influenced due to climate change and variability, inadequate water supply, labour shortage and methane emissions from rice ecosystems. This necessitates adoption action and upscaling of key adaption strategies like direct seeded rice (DSR) using validated data from rice growing areas in India. The study used experimental data of 2010–2014 and field survey data of DSR and non-DSR farmers collected during 2014. Results show that DSR method has incurred less tillage and labour costs by eluding puddling and transplantation by labour. Large-scale adoption of DSR was observed during 2012–2015 in Guntur district of Andhra Pradesh. This was mainly due to the delayed monsoon and water supply, reduction in cost of cultivation, capacity building of stakeholders and their active involvement in awareness and training programmes. The study has demonstrated that integrated extension approach in technology dissemination and scaling-out through stakeholder integration is crucial. However, a mission mode framework is needed for technology upscaling at system level.
  • ADAPTATION TO CLIMATE CHANGE: IMPACT OF CAPACITY BUILDING, INDIA

    Climate change adversely affects the determinants of agriculture. Adaptation serves as an important strategy to reduce the adverse effects of climate change (variability) and vulnerability of the people. Adaptation through an innovation programme was implemented for 4 years during 2012–2016 to improve the adaptive capacity in agriculture and the water sectors through capacity building and implementation in the Krishna River Basin, India. Primary data were collected from 178 farm households of the Nagarjuna Sagar Project command area covering both adopters and non‐adopters of water‐saving interventions from the study area. The double difference method was used to analyse the impact of adaptation through capacity building and implementation. The water‐saving interventions include alternate wetting and drying (AWD) in rice, a modified system of rice intensification (MSRI) and direct seeding of rice (DSR). The capacity building and water saving increased crop yields by 0.96, 0.93 and 0.77 t ha−1 through AWD, MSRI and DSR respectively. The three practices have increased farmers’ income and decreased the cost of cultivation in DSR by Rs.11 000 (US$169) ha−1. The methods can be more focused in canal commands on a larger scale for equal distribution of water to all the head, middle and tail‐end regions. © 2018 John Wiley & Sons, Ltd.
  • Building Farm-Level Capacities in Irrigation Water Management to Adapt to Climate Change
    Krishna Reddy Kakumanu, Yella Reddy Kaluvai, Udaya Sekhar Nagothu, Narayan Reddy Lati, Gurava Reddy Kotapati, et al.
    Irrigation and Drainage, 2018
    Climate change characterized by global warming has become a hotspot of research in recent years for water resources, agriculture, ecology and other disciplines. In India, studies have shown an increasing trend in surface temperature, with decreasing trends in rainfall. Farmers are also more affected by the climate variability which has a serious influence on their production and income. The climate change and adaptation (ClimaAdapt) programme was implemented from 2012 to 2016 to build farm‐level capacities and enhance the adaptive capacity of the agricultural and water sectors in the Krishna basin of Andhra Pradesh and Telangana states. Water‐saving interventions such as direct seeded rice, a modified system of rice intensification and alternate wetting and drying (AWD) of rice were implemented in a cluster approach and enhanced water productivity. The training and implementation programmes increased the adaptation and awareness of farmers. Water measurements were carried out by using flumes and ultrasonic sensors. The area under direct seeded rice has increased to 64% in the study district and 77% of the trained farmers are adopting the practice. Capacity building, implementation and science–policy linkages are the key pillars of the programme to improve the adaptive capacity and scaling‐up of water management practices.
