In this paper, we attempt to unpack the existing landscape of agricultural extension services and delve into questions of access to and localisation of knowledge to understand how these conditions (access and localisation) determine climate change adaptation in agriculture in the southern Indian state of Karnataka. Our empirical findings suggest that the current extension framework reproduces existing inequalities in that access to institutional knowledge and its uptake is linked to one’s social location, that is, caste, gender, class, and geographic location, and information shared is neither timely nor contextually relevant. Employing accessibility and localization as lenses of inquiry, we argue from empirical evidence that smallholder farmers in a rain-fed context are especially vulnerable to the risks posed by climatic change and hence agricultural extension (with climate-informed knowledge) should be to be seen as a critical enabler of adaptation; ensuring accessibility and localisation, we argue, strengthens climate services, and by extension, enables adaptation to climatic risks. The issues that encumber effective extension, we contend, can be mitigated by a re-imagination of agricultural extension, one that privileges public field level functionaries as conduits between state departments and farmers over other modes, and enables structured involvement of community collectives as vehicles to address local needs and ensure access. Drawing on interventions in our study sites, we make a case for promoting knowledge systems that ensure access to climate-specific agricultural information and contextual embeddedness.

The need for establishing the emerging pollutants for various rural households has witnessed a paradigm-shift towards health-related issues. Low-income groups have inadvertently contributed to environmental degradation due to improper hygienic conditions. In this paper, statistical analysis on gathered data from regional households in Karnataka has been evaluated for the health status of the individuals. A selected area based on village patterns was presented with a sample questionnaire in order to gather the patterns of household conditions prevailing in the area. A broad categorization based on the Fuzzy C clustering approach has classifiers in the form of demographic and socio-economic responses, water supply factors, sanitation, indoor air pollution, and solid waste management approaches. For each of the categories, the emerging pollutant has been identified which collectively points to ‘Poverty’ being the primary cause of deteriorating household conditions among people in such rural areas. The results of the questionnaire indicated a strong correlation between the prevalence of pollution and ill health in the low-income category of people. The authors opine that this investigation would contribute to the Government initiative of the Swachh Bharat Mission.

The over-exploitation and insufficient replenishment of groundwater (GW) have resulted in a pressing need to conserve freshwater and reuse of treated wastewater. To address this issue, the Government of Karnataka launched a large-scale recycling (440 million liters/day) scheme to indirectly recharge GW using secondary treated municipal wastewater (STW) in drought-prone areas of Kolar district in southern India. This recycling employs soil aquifer treatment (SAT) technology, which involves filling surface run-off tanks with STW that intentionally infiltrate and recharge aquifers. This study quantifies the impact of STW recycling on GW recharge rates, levels, and quality in the crystalline aquifers of peninsular India. The study area is characterized by hard rock aquifers with fractured gneiss, granites, schists, and highly fractured weathered rocks. The agricultural impacts of the improved GW table are also quantified by comparing areas receiving STW to those not receiving it, and changes before and after STW recycling were measured. The AMBHAS_1D model was used to estimate the recharge rates and showed a tenfold increase in daily recharge rates, resulting in a significant increase in the GW levels. The results indicate that the surface water in the rejuvenated tanks meets the country's stringent water discharge standards for STW. The GW levels of the studied boreholes increased by 58–73 %, and the GW quality improved significantly, turning hard water into soft water. Land use land cover studies confirmed an increase in the number of water bodies, trees, and cultivated land. The availability of GW significantly improved agricultural productivity (11–42 %), milk productivity (33 %), and fish productivity (341 %). The study's outcomes are expected to serve as a role model for the rest of Indian metro cities and demonstrate the potential of reusing STW to achieve a circular economy and a water-resilient system.
