Bio

Vartika Singh is a Senior Research Analyst in the Natural Resources and Resilience Unit, based in New Delhi, and a Senior Research Officer at the Indian Institute of Management, Ahmedabad. She is currently a doctoral candidate at Humboldt University in Berlin and a guest researcher at the Potsdam Institute for Climate Impact Research (PIK) in Germany. Her research interest is in the nexus of food-water-energy and land. She works with partial equilibrium (PE) and computable general equilibrium (CGE) models to study the integrated impact of water, energy, and climate policies toward developing sustainable transformation pathways for India in a global context. These activities constitute the core of her dissertation and are part of the CGIAR Nexus Gains Initiative. She has also worked on applied behavioral microeconomic experiments aimed at addressing barriers to sustainable intensification of agriculture as part of the Cereal Systems Initiative for South Asia (CSISA) project.

Vartika holds a master’s degree in development studies from Tata Institute of Social Sciences (TISS) in Mumbai, India, and a bachelor’s degree in economics from Hindu College, Delhi University, India.

Ending groundwater overdraft without affecting food security

Groundwater development is key to accelerating agricultural growth and to achieving food security in a climate crisis. However, the rapid increase in groundwater exploitation over the past four decades has resulted in depletion and degradation, particularly in regions already facing acute water scarcity, with potential irreversible impacts for food security and economic prosperity. Using a climate–water–food systems modelling framework, we develop exploratory scenarios and find that halting groundwater depletion without complementary policy actions would adversely affect food production and trade, increase food prices and grow the number of people at risk of hunger by 26 million by 2050. Supportive policy interventions in food and water systems such as increasing the effective use of precipitation and investments in agricultural research and development could mitigate most negative effects of sustainable groundwater use on food security. In addition, changing preferences of high-income countries towards less-meat-based diets would marginally alleviate pressures on food price. To safeguard the ability of groundwater systems to realize water and food security objectives amidst climate challenges, comprehensive measures encompassing improved water management practices, advancements in seed technologies and appropriate institutions will be needed.

FABLE Scenathon 2023: Pathways for food and land-use systems in India

Our food and land-use systems are critical for staying within our planetary boundaries and the Earth’s system resilience. Among the six Transformations required to achieve the Sustainable Development Goals (SDGs), the fourth Transformation—focusing on food, land, and water—is crucial. This Transformation is key to achieving SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production), SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land). Moreover, it significantly supports the remaining SDGs, underscoring its crucial role in fostering a sustainable future. In this document, we present the results of the 2023 ‘Scenathon’, a modelling exercise by the FABLE Consortium exploring three alternative futures for national and regional food and land-use systems. The term ‘Scenathon’ stands for ‘a marathon of scenarios’ and refers to FABLE’s iterative process for ensuring that national and regional pathways have coherent trade assumptions and align with global sustainability targets (see the 2024 Sustainable Development Report for more information).

India [in How to reduce agrifood systems’ future hidden costs? A multi-country case study]

India [in How to reduce agrifood systems’ future hidden costs? A multi-country case study]

We review the hidden costs of food systems in India as developed in the FAO SOFA 2023 report and evaluate the results in the context of India. Additionally, we assess the factors of change to reduce the hidden costs of food systems in India through a multi-model approach. We use a suite of interconnected models to implement scenarios and assess their impact on reducing the hidden costs. We create two scenarios of transformation and evaluate them across 14 indicators of food system changes encompassing the four dimensions of health, environment, inclusion, and economic costs. We also conduct stakeholder consultations to discuss the analysis and gather stakeholder opinions. We find that large average hidden cost reductions until 2050 come mainly from shift towards healthy diets, improved crop and livestock production, avoided cropland expansion and mitigated NO3 run-off. Timely shifts in dietary patterns, curbing nitrogen emissions from cropland surface runoff, and managing land use change emerge as pivotal factors for reduction of hidden costs in India. Our analysis points towards the importance of assessment of hidden costs of food systems in India using existing data and evidence. At the same time, the results from our analysis highlight the importance of reviewing analysis of hidden costs, methodological validation, and forward-looking projections within agrifood systems.
