Emerging Issues and Potential Opportunities in the Rice–Wheat Cropping System of North-Western India

Abstract

The rice–wheat cropping system (RWCS) is the backbone of Indian farming, especially in the north-western region. But continuous adoption of the RWCS in northwest India has resulted in major challenges and stagnation in the productivity of this system. Additionally, the Indo-Gangetic Plains of Pakistan, Nepal, and Bangladesh are also facing similar challenges for sustainable production of the RWCS. Several emerging problems, such as the exhausting nutrient pool in soil, deteriorating soil health, groundwater depletion, escalating production cost, labor scarcity, environmental pollution due to crop residue burning and enhanced greenhouse gas emissions, climatic vulnerabilities, and herbicide resistance in weed species, are a few major threats to its sustainability. To address these challenges, a wide range of sustainable intensification technologies have been developed to reduce the irrigation and labor requirements, tillage intensity, and straw burning. Awareness and capacity building of the stakeholders and policy matching/advocacy need to be prioritized to adopt time- and need-based strategies at the ground level to combat these challenges. This review summarizes the current status and challenges of the RWCS in the northwest region of the country and also focuses on the precision management options for achieving high productivity, profitability, and sustainability.

How can we build inclusive circular supply chains? Examining the case of agricultural residue usage in India

“…We should also strive for system‐level changes in the development of agriculture in northern India. In that work, key issues are water use, soil quality and the socio‐economic status of the farmers (Dhanda et al, 2022; Singh, 2021). Fairly organised collection and selling of straw can be one part of the solution.…”

Scale to Assess the Sustainability of Rice-Wheat Cropping System

“…However, these changes made the RWCS more resource intensive, resulting in soil degradation and ground water depletion, threatening the system's sustainability (Chauhan et al, 2012;Kumar et al, 2018). Other major threats to its sustainability include an exhausted nutrient pool of soil leading to its deterioration, groundwater depletion, rising production costs, labour scarcity, environmental pollution caused by improper crop residue management and increased greenhouse gas (GHGs) emissions, herbicide resistance in weeds, all contributing to climatic vulnerabilities (Dhanda et al, 2022). Farmers have been discouraged from pursuing other sustainable cropping methods due to insufficient procurement and assured minimum support price (MSP) regime, irrigation, and electricity facilities at subsidised rates.…”

Socio-economic Determinants Influence on NiliRavi Buffalo Farmers Choice of Milk Marketing Channels in Punjab

“…Punjab state experienced decline in the crop husbandry income and shrunken employment opportunities because of over exploitation of the resources under rice-wheat cropping system (Dhanda et al, 2022). The state recorded 133.47 lakh tonnes of milk production with per capita availability of 1035 grams per day, highest in the country (NDDB).…”
