The study identifies factors behind the groundwater depletion in Punjab (India) and examines the economics of groundwater irrigation across farm-size categories, varied groundwater levels and energy policy scenario. The farm-level evidences point out that farmers with smaller land holdings incur 2-3 times groundwater cost than those with larger land holdings. Also, small farmers are affected more adversely due to falling groundwater level. Further, financial expenses in extracting groundwater are borne equally by the society and the farmers. The withdrawal of energy subsidy is expected to reduce net returns, but at a varying rate across different crops. However, crop cultivation would still be profitable and desubsidization will result in 29-82% savings in existing groundwater use in different crops.Keywords

Prioritizing and targeting less developed regions is one of the multi-pronged strategies for doubling farmers’ income (DFI) in India. Using an indicator approach, the present study assessed and mapped agro-ecological sub-regions (AESRs) based on ten indicators representing production, infrastructure, information, marketing and income of the farmers. On the basis of the composite index of agriculture development, AESR 9.1 and AESR 1.1 were found to be the most and the least developed regions respectively. Further, the potential districts for each of the less-developed AESRs have been identified for greater prudency in planning. The study concludes that for achieving the target of DFI within the stipulated time-frame, it is imperative to mainstream AESR-based planning in technological development and dissemination. The evidences revealed large and equitable response of the efforts targeted towards less-developed regions.Keywords

Honey bees forage owing to their remarkable ability to learn and memorize their cues. The effect of thiamethoxam on the memory of bees was studied through the proboscis extension reflex (PER). The bees that consumed higher doses of thiamethoxam (0.93–5.76 ng bee–1) showed lesser sensitivity to sucrose than those that consumed lower doses (0.03–0.64 ng bee–1). Bees sensitivity was least affected at the highest sucrose concentration (50% w/v). PER in trained and treated bees recorded after 2 and 24 h of consuming the various doses of thiamethoxam showed a significant reduction in memory (13.3–82.2% and 0.00–68.9% respectively). Field-level studies are required to validate the results and formulate strategies at the national level for safeguarding the bees.Keywords
