1.22. Ola’s mega-factory Ola commenced construction of the worldʼs largest two-wheeler mega-factory on a 500-acre site in Tamil Naduʼs Krishnagiri district. Relevance: Forward & backward linkages S Agglomeration effect Balanced regional development Defeminisation in Indian agriculture for over three decades I A It has been observed that while proportion of labour force working in agriculture D declined over the 1990s, the proportion of women working in agriculture increased in developing countries eg: Nepal, Bangladesh. Agriculture, being the least paid sector within the rural economy, is expected to witness increasing rural areas. E E participation of women, with men seeking better opportunities within and outside However in India, as seen in a long-term perspective, there is a trend which is C contrary to the above mentioned fact. For the last three decades, there has been a consistent fall in both female labour force and work force participation, both in rural and urban areas; the fall in the rural area is more consistent and sharp, in C relation to male work participation. In India the share of women workers in agriculture has fallen from 44% to 30% in last three decades(1990-2020): U Reasons for this decline: S 1. Increased attendance of woman in educational institutions 2. higher income levels of households resulting in withdrawal form workforce 3. structural shift away from agriculture 4. increased mechanisation in agriculture 5. fall in the importance of animal husbandry Menʼs employment status depended largely on the economic development of the state, where as womanʼs WPR was guided by societal norms. 14 www.succeedias.com © Succeed IAS
Workplace interactions and social capital Social capital can be defined as the links, shared values and understandings in society that enable individuals and groups to trust each other and so work together. At workplaces woman are most likely to interact with women, less likely to interact with those belonging to other projects and higher occupational ranks as compare to men who are more likely to have considerable horizontal as well as S vertical linkages within and beyond workplace. In ITeS more than 60% of the woman interact mostly with women colleagues while I A for those in the IT the proportion is slightly above 40%. More than 70% of the men respondents in the new generation sectors (NGSs) tend to interact with mixed gender groups. D Besides gender functional and occupational rank of the peer groups of an individual also plays a crucial role. Interaction with high-level officials accords E employees with greater access to sources of authority, formal power and control within the organisation as compare to the lower level positions. E For the woman such restrictive patterns of workplace interactions not only results in loss of access to empowering information, but also other career benefits such as C resources, mentorship and support from colleagues. C Women also reportedly abstain from the informal socialisation taking place outside office hours where valuable job related information gets circulated.

6. Coastal zone management 7. Geology mineral resource management Remote sensing and GIS can be used to manage the limited natural resources in an effective and efficient manner. Geospatial data is effective in the analysis and determination of factors that affect the utilisation of this resources. The technologies provide a platform through which we can generate information that can be used to make sound decisions for sustainable development of natural resources in India. g-Governance A S I g-Governance can be described as a geospatial plugin to e-Governance, acting as an extended module with the additional functionality of geospatial technology. Geospatial data acts as a backbone for g-Governance. society using ICT. E D g-Governance has established a framework for Indiaʼs vision of a socially inclusive E Source of geospatial data: Earth observation satellites: RISAT, Cartosat, Oceansat and INSAT. Applications: C C tele-medicine, tele-education, disaster risk reduction. Eg: during Kerala floods ISRO provided near real-time information on flood extent by using satellite data. S U Case study: Kerala flood • Unusually heavy summer monsoon rains caused disastrous floods across Kerala. • More than 324 people died and at least 1 million were relocated. • All 14 districts of Kerala were placed on red alert. • 1/6 of its total population was directly affected by the floods and its related incidents. • Heavy rains in Wayanad and Idukki caused several landslides and left the hilly districts isolated. • The extensive flooding of agricultural lands resulted in crop losses estimated at around 150 to 200 Billion. • Coffee, rubber, tea and black pepper were amongst the most affected crops. 16 www.succeedias.com © Succeed IAS

Sponge City Concept What is a Sponge City? The Sponge City indicates a particular type of city that does not act like an impermeable system not allowing any water to filter through the ground, but, more like a sponge, actually absorbs the rain water, which is then naturally filtered by the soil and allowed to reach into the urban aquifers. This allows for the extraction of water from the ground through urban or peri-urban wells. This water can be S easily treated and used for the city water supply. What are the key issues the Sponge City wants to solve? A • Less water available in urban and peri-urban areas. I • Polluted water discharged into rivers or the sea. • Degradation of urban ecosystems and green areas due to sprawling • Increase in the intensity and frequency of urban flooding. What does a Sponge City need in practise? • Contiguous open green spaces • Green roofs D What are the benefits of Sponge city E • More clean water for the city • Cleaner groundwater • reduction in flood risk • Porous designs • Water savings and recycling C E • Lower burdens on drainage systems • Greener healthier and more sustainable urban spaces • Enriched biodiversity U C S 18 www.succeedias.com © Succeed IAS
Compact city The term 'compact city' was first coined in 1973 by George Dantzig and Thomas Saaty, according to Randal O'Toole, Le Corbusier with his Radiant City plan is one of the first protagonist of the compact city concept. the concept experienced a resurgence of interest in 1980s as a response to the global challenge to sustainability goals and climate-change concerns. The term S compact city does not have a universally accepted definition. It is a combination of many strategies with the overarching aim to create compactness and high density that can avoid all the problems of modern cities and urban sprawls. The I A single most important attribute to describe a compact city is the population density supported by concepts like mixed land use with higher density, geographic limit of the city boundary, and promotion of public Transport as mode of communication vis-a-vis private vehicle. E D The concept of compact city was endorsed by United Nations Earth Summit Agenda 21(1993) and European commission through its publication ʻcities of tomorrowʼ. The compact city approach was adopted by many european states and E gained popularity. Criticism C C Analytical studies cautioned against hyperdensity and advised viable settlements at optimal densities for the human scale. Some geographers opposed this concept and noted that sustainable urban development points towards decentralised concentration i:e relatively small cities U with a high density and short distances between houses and public/ private spaces. S In the context of developing countries the critique of complexities was even stronger as the developing countries are associated with a range of problems due to high densities like infrastructure overload, overcrowding, congestion, air- pollution, severe health hazards, lack of public and green open space and environmental degradation. 19 www.succeedias.com © Succeed IAS
