“…The impact of climate change is especially more severe in the rainfed regions of South Asia. Rainfed agriculture in India currently accounts for about two-thirds of the total cropped area and nearly half of the total value of agricultural output and nearly half of all food grains are grown under rainfed conditions (Roul et al, 2015;Singh et al, 2021). Sapkota et al (2015) reviewed the effects of CA from the perspective of adaptation to heat and water stresses, and reduction GHG emissions in South Asia.…”

“…Accordingly, India offers a potentially unique example in the development of models and mechanisms by which nutritional needs can be addressed sustainably (Ritchie et al, 2018). Food security of the poor will be at risk due to disproportionate population growth and limited arable land (Roul et al, 2015).…”

This article examines and compares the status of land rights and their impacts on agricultural productivity, food security and well-being in a set of tribal and non-tribal villages in Telangana. Based on an intensive field survey, the research confirms that tribals without formal land rights remain largely unable to benefit from government support and access to private institutions in terms of getting credit and farm extension, whereas in non-tribal villages, government organisations are pro-active in providing such support. These findings confirm the need to increase the effectiveness of land rights and title documentation in India’s tribal villages to protect local people’s investments in land, enhance agricultural productivity and strengthen the long-term effectiveness of government programmes, which include avoidance of migration to the big cities.

“…One approach to addressing these issues is the introduction and adaptation of conservation agriculture production systems (CAPSs). CAPS are defined as integrated production systems consisting of minimum soil disturbance, appropriate crop rotation or intercropping, and continuous organic soil cover ( Roul et al, 2015 ). The integrated nature of CAPS builds on decades of research in more large-scale and mechanized farming systems in which zero- or minimum-tillage systems were developed and combined with crop rotation and residue retention or cover cropping to reduce soil erosion and related declines in soil and natural resource quality ( Idol, 2015 ).…”

Traditional agriculture in rainfed uplands of India has been experiencing low agricultural productivity as the lands suffer from poor soil fertility, susceptibility to water erosion and other external pressures of development and climate change. A shift toward more sustainable cropping systems such as conservation agriculture production systems (CAPSs) may help in maintaining soil quality as well as improving crop production and farmer’s net economic benefit. This research assessed the effects over 3 years (2011–2014) of reduced tillage, intercropping, and cover cropping practices customized for maize-based production systems in upland areas of Odisha, India. The study focused on crop yield, system productivity and profitability through maize equivalent yield and dominance analysis. Results showed that maize grain yield did not differ significantly over time or among CAPS treatments while cowpea yield was considered as an additional yield in intercropping systems. Mustard and horsegram grown in plots after maize cowpea intercropping recorded higher grain yields of 25 and 37%, respectively, as compared to those without intercropping. Overall, the full CAPS implementation, i.e., minimum tillage, maize–cowpea intercropping and mustard residue retention had significantly higher system productivity and net benefits than traditional farmer practices, i.e., conventional tillage, sole maize cropping, and no mustard residue retention. The dominance analysis demonstrated increasing benefits of combining conservation practices that exceeded thresholds for farmer adoption. Given the use of familiar crops and technologies and the magnitude of yield and income improvements, these types of CAPS should be acceptable and attractive for smallholder farmers in the area. This in turn should support a move toward sustainable intensification of crop production to meet future household income and nutritional needs.
