Kochi

Kochi, historically known as Cochin, is a prominent port city situated on the Malabar Coast of India, bordering the Laccadive Sea. It forms part of the Ernakulam district in the state of Kerala. Often referred to as the "Queen of the Arabian Sea," Kochi has been a crucial spice trading hub since ancient times, attracting traders from Rome, Persia, Arab nations, and China.

Its strategic location and natural harbor have contributed significantly to its commercial prosperity over centuries, evolving from a fishing village into a bustling metropolis. The city officially reverted to its original Malayalam name, Kochi, in 1996, a change upheld despite municipal corporation challenges.

Today, it stands as Kerala's financial, commercial, and industrial capital, recognized for its economic dynamism and modern infrastructure.

• Cochin International Airport holds the distinction of being the world's first airport to operate entirely on solar energy [6].
• A 2011 study by the McKinsey Global Institute identified Kochi as one of 28 Indian cities poised to contribute 50% of the world's GDP by 2025 [7].
• In July 2018, global professional services firm JLL recognized Kochi as India's topmost emerging future megacity [8], [9].
• The city consistently ranks high in tourism, being the top destination in Kerala for international and domestic tourist arrivals [10].
• Kochi was ranked seventh globally by Lonely Planet in its list of top 10 cities to visit in 2020 [11].

The city of Kochi is governed by the Kochi Corporation, led by a mayor and divided into 74 administrative wards, with council members elected for five-year terms. The corporation's main headquarters are in Ernakulam, complemented by zonal offices in Fort Kochi, Mattancherry, Palluruthy, Edappally, and Pachalam [13]. General city administration is managed by the Personnel Department and the Council Standing Committee Section, encompassing diverse departments such as town planning, health, engineering, revenue, and accounts.

Additionally, the Kochi Municipal Corporation is responsible for essential services like waste disposal and sewage management, with a significant portion of daily waste converted into organic manure at the Brahmapuram Solid Waste plant. The Kerala Water Authority supplies potable water from the Periyar River [14], while the Kerala State Electricity Board provides electricity to the city. The Greater Cochin Development Authority (GCDA) and Goshree Islands Development Authority (GIDA) are key government bodies that oversee and facilitate infrastructure development in the larger Greater Cochin area [15].

Kochi is widely recognized as the financial and commercial capital of Kerala, boasting a dynamic economy driven by various sectors. The district itself contributes a significant 15.1% to the state's GDP. Major industries include construction, manufacturing, shipbuilding, transportation, seafood and spice exports, chemical industries, information technology (IT), tourism, healthcare, and banking.

The city has experienced substantial investment in recent years, positioning it as one of India's fastest-growing second-tier metropolitan areas [16]. Notably, remittances from non-resident Indians (NRIs) form a considerable source of income for the region. Eloor, located north of the city center, stands as Kerala's largest industrial belt, housing over 250 factories producing a wide array of goods, from petrochemicals to fertilizers. Key industrial players like Fertilizers and Chemicals Travancore Limited (FACT) and Kochi Refineries (BPCL) further underscore the city's industrial prowess.

Kochi's business environment is bolstered by several advantageous factors, including a reliable electricity supply, abundant fresh water, a long coastline, and extensive backwaters. The presence of a major port, a container trans-shipment terminal, a harbor terminal, and an international air terminal have collectively spurred industrial growth in the city and its surrounding district.

The city is a significant exporter of spices, hosting the International Pepper Exchange and the headquarters of the Spices Board of India and the World Spice Organisation. The burgeoning IT and ITES sectors also contribute to Kochi's economic vitality, benefiting from affordable bandwidth via undersea cables and lower operational costs compared to other major Indian cities. Government-backed initiatives such as InfoPark and the Cochin Special Economic Zone, alongside private developments like SmartCity at Kakkanad [17] and the planned Cyber City at Kalamassery [18], are actively fostering a robust technology and industrial ecosystem.

Kochi boasts a well-developed infrastructure that supports its dynamic urban landscape. Its air gateway is the Cochin International Airport (CIAL), located approximately 28 km north of the city, handling both domestic and international flights. Notably, CIAL is the first international airport in India built without central government funding and the world's first fully solar-powered airport [6].

The city is well-connected by a network of national highways, including NH 66, NH 544, NH 966A, and NH 966B [21], [22], linking it to neighboring cities and states. Public transport within Kochi is robust, featuring extensive private and state-run bus networks, an integrated Mobility Hub at Vyttila, and a modern metro rapid transit system, the Kochi Metro, which is being developed in phases to ease traffic congestion. The city's maritime infrastructure is equally significant, with the Cochin Port serving as one of India's major seaports and offering comprehensive cargo and passenger facilities. Additionally, Kochi is home to India's first water metro project, an integrated water transport system connecting ten islands through a network of routes and jetties [5].

Kochi is rapidly emerging as a significant technology hub in India, driven by the growth of its Information Technology (IT) and IT Enabled Services (ITES) industries. The city benefits from the availability of cost-effective bandwidth, facilitated by undersea cables, and lower operational expenses compared to other major Indian cities, making it an attractive destination for tech companies.

Several government-promoted technology and industrial parks, such as InfoPark and the Cochin Special Economic Zone, are operational on the city's outskirts, fostering a vibrant tech ecosystem. Private sector initiatives, including the SmartCity project at Kakkanad [17] and the planned Cyber City at Kalamassery [18], are further expanding the city's IT infrastructure and creating integrated IT townships. Beyond software and services, Kochi also possesses a well-established electronics hardware industry, with companies like V-Guard Industries and SFO Technologies having a presence. The Government of Kerala is actively supporting this sector with plans for an Electronic City industrial park spanning 340 acres [19], and private operators like NeST are developing Special Economic Zones specifically for electronics hardware [20].
