Farmers in peri-urban areas of developing countries depend on wastewaters for their livelihood but with grave health and environmental risks. An 8-year field experiment compared food grain (FGPS), agroforestry (AFS), fodder (FPS) and vegetable (VPS) production systems and quantified responses to fertilizers (NP 25–100%) when irrigated with sewage (SW; EC 1.3 ± 0.3 dS m-1 BOD 82 ± 11, NO3–N 3.2 ± 0.4, NH4–N 9.6 ± 0.5, P 1.8 ± 0.3, K 6.4 ± 0.4 mg L-1) vis-à-vis groundwater (GW). Productivity improved with SW by 14–28% while trends were negative with sub-optimal NP under GW. Partial factor productivity (PFP) averaged 18.0, 11.1, 157 and 149 kg kg-1 NP with GW in FGPS, AFS, FPS and VPS, respectively. Counter figures were 13.8, 8.8, 96 and 56 kg kg-1 NP with SW. Paddy-wheat equivalent yields were 5.5, 1.8 and 19.9 fold under AFS, FPS and VPS with SW. About 40, 33, 75 and 20% of fertilizer NP with SW was sufficient for similar production as with recommended NP and GW in FGPS, AFS, FPS and VPS, respectively. Quality of produce improved in terms of crude protein and the micronutrients in edible parts with SW while toxic metals were within the permissible limits. However, the keeping quality of vegetables was lowered due to faster decay with pathogens contamination (Aerobic bacterial plate counts 5 × 105–4.2 × 108 cfu g-1 and Escherichia coli <2 × 102–7 × 105). Thus, the sewage proved as a vital resource in improving productivity, sustainability and saving fertiliser costs but this may pose health risks because of pathogenic infestation that need to be regulated.

Since irrigation with under-treated wastewater is growing in many underdeveloped countries, its regulation should follow more efficient and less polluting approach. Therefore, the nutrient balances and soil properties were monitored in an 8-year experiment where the food grain (FGPS, paddy–wheat), fodder (FPS, sorghum-Egyptian clover) and vegetable (VPS, gourds/okra-cabbage/cauliflower) and agroforestry (AFS, poplar–paddy–wheat) production systems were irrigated either with sewage water (SW, BOD 82 ± 11, NO3–N 3.2 ± 0.4, NH4–N 9.6 ± 0.5 and P 1.8 ± 0.3 mg L-1) or good quality groundwater (GW) along with variable doses of N & P (25–100% of the recommended). The concentration and uptake of both N and P increased with SW and NP doses. SW enhanced N uptake by 29, 23, 18 and 37% in FGPS, AFS, FPS and VPS, respectively, while the corresponding values were 28, 21, 29 and 35 per cent for P uptake. The crop N removal obtained at 100% NP dose in GW were at par with 25% NP doses in AGF and VPS and 50% NP doses in FGPS and FPS with SW. The positive balances of nutrients with SW resulted in improvement in soil organic carbon and available status of nitrogen and phosphorus. Soil microbial biomass carbon (MBC) and activities of dehydrogenase, urease and phosphatase also improved substantially with SW. The most of nitrate-N was retained in the surface 0.3 m soil especially its leaching was minimal under AFS. Overall results indicated for improvement in the awareness of the growers for adjusting NP doses and non-dependent on water guzzling crops like paddy to minimise the fertiliser costs and the contamination of groundwater.

Irrigation experiments were conducted during November to April under wheat crop in the winter season of 2012-13 and 2013-14 in the farmer’s field at Galibkhedi village located in Karnal District, Haryana State, India. In the study, collapsible multi-outlet pipe (MOP) along with single outlets pipe (SOP) was tested in farmer’s field under wheat cultivation. Irrigation was carried out in five treatments including tillage (T) with SOP and MOP; zero-tillage (ZT) with SOP and MOP, and furrow irrigation with raised bed (FIRB). Iso-time profile of waterfront spreading and advance indicated that irrigation water distribution was uniform under the plot irrigated using MOP as compared to plot irrigated using SOP. In addition, water distribution was uniform under zero tilled plots as compared to tilled plot. Results implied that MOP has several advantages over SOP in terms of application efficiency (AE) and uniformity of water distribution. Average application efficiency for the first study year was found to be in the order of ZT-MOP (82.41%) > FIRB (76.79%) > ZT-SOP (75.25%) > T-MOP (74.85%) > T-SOP (69.79%). Average application efficien-cy for the second study year was found to be in the same order as first year with some deviation in values. In the second year values of mean application efficiencies were ZT-MOP (82.58%) > FIRB (77.13%) > ZT-SOP (73.04%) > T-MOP (69.65%) > T-SOP (66.13%). Overall, this study concludes that irrigation under wheat crop using collapsible multi-outlet pipe (MOP) with zero tillage practices is a suitable option for surface irrigation that accomplishes uniform distribution of water with higher application efficiency.

Increased participation of women in the agricultural technology adoption decision by farm households is one of the key indicators of gender empowerment in the agricultural sector. This study examines whether women’s participation in the household decision to adopt agricultural technology affects the adoption of climate-smart agriculture (CSA), using data collected from 1,267 farm households from two Indian states of Bihar and Haryana. When we considered the sex of the household head (using a dummy variable for male-headed vs female-headed household) as a basis of analyzing the role of gender in the adoption of CSA, we found that women in Haryana had no role in the adoption of CSA. On the contrary, when we considered women’s participation in technology adoption decisions as a basis of gender analysis, we found that women’s participation in technology adoption decisions in Haryana is much higher as compared to Bihar. Consequently, the likelihood to adopt CSA is higher in Haryana than in Bihar. We also found that wealth, training, and access to extension and market positively influenced CSA adoption. Qualitative analysis shows that women farmers prioritize family food security rather than farm income, and therefore, they are more likely to focus on CSA to ensure food security.

In the Indo-Gangetic Plains, one of India’s most productive agricultural regions, smallholder livelihood vulnerability can inhibit sustainable development. As there are significant differences in economic development, natural resources and agricultural productivity within the region, we estimate the Livelihood Vulnerability Index in two districts (Vaishali, Bihar and Karnal, Haryana) to determine suitable adaptation strategies under diverse conditions. To reflect different aspects of climate exposure, we include both self-reported climate shocks and spatially interpolated weather data. The assessment of 1127 households shows that while both districts have similar exposure and adaptive capacity levels, the sensitivity dimension makes Vaishali more vulnerable to climate change. To reduce sensitivity, decision-makers should focus on improving infrastructure (e.g., permanent housing, latrines, health centers, alternative energy sources). To improve adaptive capacity and reduce climate risk in both regions, policymakers should promote the expansion of extension training for livelihood diversification, information and communication technologies as well as conservation agriculture.
