1. Geography of Punjab
Introduction

2. Punjab is a state in the northwest of the Republic of India, forming part of the larger Punjab region.
The state is bordered by the Indian states of Himachal Pradesh to the east, Haryana to the south and southeast and Rajasthan to the southwest as well as the Pakistani province of Punjab to the west. It is also bounded to the north by Jammu and Kashmir. The state capital is located in Chandigarh, which is a Union Territory and also the capital of the neighbouring state of Haryana.
Major cities of Punjab include Amritsar,  Jalandhar, Ludhiana, Patiala,  Tarn Taran Sahib,  Nawanshahr,  Firozpur,  Bathinda, Hoshiarpur and  Mohali.
After the partition of India in 1947, the Punjab province of British India was divided between India and Pakistan.
The Indian Punjab was divided in 1966 with the formation of the new states of Haryana and Himachal Pradesh, as well as the current state of Punjab. Punjab is the only state in India with a majority Sikh population.

3. The Greeks referred to Punjab as Pentapotamia, an inland delta of five converging rivers.
In  Avesta, the sacred text of Zoroastrians, the Punjab region is associated with the ancient hapta həndu or  Sapta Sindhu, the Land of Seven Rivers. 
Historically, the Punjab region has been the gateway to the Indian Subcontinent for people from Greece, Central Asia, Iran, and Afghanistan and vice versa.
The word Punjab is from Sanskrit and Persian words panj (Sanskrit: पंच) and Āb (Persian: آب‎, (which itself derives from "āp" Sanskrit: अाप्) that means "five" and "water", respectively, thus PanjĀb means "Five Rivers", which roughly means "Land of Five Rivers”. 
The five rivers are the Beas, Sutlej, Ravi, Chenab and  Jehlum (also spelled Jhelum). Traditionally, in English, there used to be a definite article before the name, i.e. "The Punjab”. The name is also sometimes spelled as "Panjab".

4. Location
Punjab is located in northwestern India, and has an area of 50,362 km2. It extends from the latitudes 29.30° North to 32.32° North and longitudes 73.55° East to 76.50° East. It is bounded on the west by Pakistan, on the north by Jammu and Kashmir, on the northeast by Himachal Pradesh and on the south by Haryana and Rajasthan.

6. Most of the Punjab lies in a fertile plain, alluvial plain with many rivers and an extensive irrigation canal system.  
A belt of undulating hills extends along the northeastern part of the state at the foot of the Himalayas.
Its average elevation is 300 meters above sea level, with a range from 180 meters in the southwest to more than 500 meters around the northeast border.
The southwest of the state is semiarid, eventually merging into the Thar Desert. The Shiwalik Hills extend along the northeastern part of the state at the foot of the Himalayas.
The soil characteristics are influenced to a limited extent by the topography, vegetation and parent rock. The variation in soil profile characteristics are much more pronounced because of the regional climatic differences.
Punjab is divided into three distinct regions on the basis of soil types: southwestern, central, and eastern.
Punjab falls under seismic zones II, III, and IV. Zone II is considered a low-damage risk zone; zone III is considered a moderate-damage risk zone; and zone IV is considered a high-damage risk zone.

7. The area of Punjab can be divided into:
Malwa is a region of Punjab south to river satluj. The Malwa area makes up majority of the Punjab region consisting 11 districts. Cities such as Ludhiana,Patiala, Sangrur, Bhatinda and Mohali located in the Malwa region. Malwa is also famous for cotton farming.
Majha is a historical region of the Indian Punjab comprising the modern districts of Amritsar, Pathankot, Gurdaspur and Tarn Taran. It lies between rivers Ravi, Beas and the Sutlej. This region is called heartland of punjab, it is also celebrated as being the 'Cradle of Sikhism'.
Doaba is the region of Indian Punjab between the rivers Beas and Sutlej. The name "Doaba" literally translates to "land between two rivers" ("Do" two, "Ab" river; Punjabi). It is one of the most fertile regions of the world, and was the centre of the Green Revolution in India. To this day, it remains one of the largest per capita producers of wheat in the world.The biggest cities in Doaba areJalandhar, Hoshiarpur, Nawanshahr and Kapurthala.

Also Punjab State has been awarded National Productivity Award for agriculture extension services for consecutively ten years from to and 2001 to
In recent years a drop in productivity has been observed mainly due to falling fertility of the soil.
This is believed to be due to excessive use of fertilizers and pesticides over the years.
Also a big worry is the rapidly falling water table on which almost 90% of the agriculture depends, which has witnessed alarming drops in recent years.
By some estimates, groundwater is falling by a meter or more per year.
