Improved soil and water management practices can reduce moisture stress and crop failures associated with rain-fed cropping systems. Little information exists on soil and water management technologies requirements for male and female farmers in different agro-ecological regions. The objective of current study was to investigate farmers’ sources of information and perceptions on soil and water management technologies. Four sites selected from different agro-ecological regions (AERs), sub-humid (Mazowe/Goromonzi, and Kadoma) and semi-arid (Matobo and Chiredzi). Data on sources of information on soil and water management, types of technologies preferred by farmers and constraints to adoption of technologies were collected through household interviews and focus group discussions. Results showed that government extension agents, farmer-to farmer extension and non-governmental organizations were the main sources of information on soil and water management technologies at all the sites. NGOs mainly provide information on reduced tillage methods. Main technologies were mulching (61%), reduced tillage methods (53%), and contour ridges (33%) in Mazowe/Goromonzi district, reduced tillage method (83) and mulching (64%) in Kadoma, and reduced tillage methods (54%) and contour ridges (47%) in Matobo. More farmers used soil and water management technologies at the sub-humid sites than at the semi-arid sites. Soil and water conservation technologies used were similar between male-headed (MHH) and female-headed households (FHH). Soil and water conservation technologies used by farmers matched their preferences in two of the four study sites. The findings are important for targeting soil and water management practices in the various agro-ecological zones.

CONTEXT: Millions of people living in the Eastern Gangetic Plains (EGP) of India engage in agriculture to support their livelihoods yet are income poor, and food and climate insecure. To address these challenges, policymakers and development programs invest in irrigation-led agricultural intensification. However, the evidence for agricultural intensification to lift farmers' incomes above the poverty line remains largely anecdotal.
OBJECTIVE: The main objective of this study is to use a large household survey (n = 15,572; rice: 8244, wheat: 7328; 2017/18) to assess the link between agricultural intensification and personal daily incomes from farming (FPDI) in the rice-wheat systems of the EGP – the dominant cropping system of the region.
METHODS: We use the Intensification Benefit Index (IBI), a measure that relates farm size and household size to FPDI, to assess how daily incomes from rice-wheat production change with irrigation-led intensification across the EGP.
RESULTS AND CONCLUSIONS: Relative to the international poverty line of 1.90 Purchasing Power Parity (PPP)$ day-1 and accounting for variations in HH size in the analysis, we found that small farm sizes limit the potential for agricultural intensification from irrigation to transform the poverty status of households in the bottom three quartiles of the IBI. The estimated median FPDI of households with intensified systems in the bottom three quartiles is only 0.51 PPP$ day-1 (a 0.15 PPP$ gain). The median FPDI increases to 2.10 PPP$ day-1 for households in the upper quartile of the IBI distribution (a 0.30 PPP$ gain). Irrigation-led agricultural intensification of rice-wheat systems in the EGP may provide substantial benefits for resilience to climatic change and food security but achieving meaningful poverty reduction will require complementary investments.
SIGNIFICANCE: Transforming the poverty status of most smallholder farmers in the EGP requires diversified portfolios of rural on- and off-farm income-generating opportunities. While bolstering food- and climate security, agronomic intervention programs should consider smallholders' limited monetary incentives to invest in intensification. Irrigation-led agricultural intensification programs and policies should explicitly account for the heterogeneity in household resources, irrigation levels, and degree of dependence on agricultural income.
