Abstract

Soil fertility has direct implications on the agricultural production scenarios of a region. Surface soil samples at 1 km grid were collected to assess the fertility status of Lakhimpur district (Assam) in North East India. Fertility parameters like soil organic carbon, available nitrogen, phosphorus, potassium, iron, manganese, zinc and copper were determined using standard analytical procedure. Spatial distribution maps of the soil parameters were generated using regularized spline method in ArcGIS 10.0. The average soil organic carbon content was 1.05% and the maximum area was under high availability status (78%). In the case of nitrogen, 57% of the area was under low availability status. In the case of available potassium and phosphorus, the areas under low availability status were 48% and 49% respectively. But for micronutrients, in general, the availability status was high except for zinc, which indicated that 40% of the area was under low availability. A methodology was developed to integrate the individual nutrient layers using a set of decision rules to identify the multinutrient deficient zones. The integrated map showed that 24% of the area had multiple nutrient deficiencies and fell under high priority zone that warrant immediate nutrient management interventions to mitigate the situation.

Abstract

The seagrass meadows of Sethukarai coast are unique in nature, housing high faunal diversity compared to other coastal areas. A rare live specimen of bandtail scorpionfish Scorpaenopsis neglecta was found near a burrow dug by an alpheid shrimp. Taxonomy, mor-phometric and meristic characters, adaptive, beha-vioural and colour-switching physiological camouflage trait of the S. neglecta are elaborated in this commu-nication. Visual in situ documentation of feeding ha-bits of scorpaenids and their preying behaviour, especially that of lionfish Pterois volitans preying on goby fish is presented. Mutualism exhibited by goby fish Amblyeleotris gymnocephala with the alpheid shrimp Alpheus rapax and the importance of habitat protection from anthropogenic activities are also dis-cussed.

Abstract

India’s New Education Policy 2020, which is in tune with SDG 4 (quality education) and SDG 8 (decent work and economic growth), has stressed the redesigning of vocational education (VE) to equip the youth for the world of work, considering the window of opportunities available till 2040. Though the competence gap is being pronounced as the foremost hurdle in the ‘education–world of work’ transition in every sector, its precise measurement and quantification remain elusive. In this context, we have develop an innovative methodological framework and a composite index (h) to measure the competence gap of the vocational higher secondary education system (VHSES), taking marine fisheries and seafood processing courses offered under the VHSES in Kerala, India as a case study. This study demonstrates that the educational gap, delivery gap, propensity to normalize with general education and inadequate learning ecosystem are responsible for the ‘education–world of work mismatch’ in VE. The findings of the present study point to specific areas of VE that need pedagogic and pragmatic reconstruction. It also shows strategic policy considerations to place the learners’ aspirations, gender and vocational opportunities in a balanced manner for a better vocational teaching–learning ecosystem.

Abstract

Climate change and associated weather aberrations are wreaking havoc on the performance of production systems worldwide. Because of their proximity to the sea and risk of exposure, coastal wetlands are regarded as one of the most climatically vulnerable production systems. As a result, interventions to improve their adaptation and resilience to climate change are critical. We attempted to investigate the multifunctional ecosystem roles and services provided by the Pokkali and Kaipad paddy-based rotational farming systems on the southwest coast of India, which are being revived through a pilot programme implemented by the Kerala Agency for Development of Aquaculture. The physical and economic dimensions of the ecosystem services/disservices are assessed, and policy options for further land revival and area expansion of such wetlands are proposed.

Keywords

Climate Mitigation, Ecosystem Services, Ecosystem Valuation, Market Price Method, Pokkali/Kaipad Ecosystems, Replacement Cost Method, Wetland Ecosystem.
