CHAPTER II

PHYSICAL AND SOCIAL PROFILE OF STUDY REGION

2.1 INTRODUCTION

Relief, physiography, geology, climate and natural vegetation are

the principal elements of the physical setup of the region that plays significant

role in configuration of the landforms, hydrology and morphometry of river

development. Geographical set up of region has therefore; control on the socio-

economical status of human population. Agricultural development of the upper

Krishna basin is controlled due to the natural hazards both physical and

cultural factors, which are unevenly distributed and developed. Flood and

drought disaster causes are related with the physical set up and climatical

elements. The attempt here has been made to study the impact of physical and

social factors on the development of the region due to river linkages for that

Landuse; agricultural scenario etc. has been duly looked into this chapter.

2.2 GEOGRAPHICAL SETUP

Geographical setup of the upper Krishna basin is conspicuous with

several characteristic topographical features and climatic conditions. While

looking into the geographical setup here region, topography, geology, drainage

and soil are the factors taken into consideration.

The study region ‘Upper Krishna Basin’ extends between 15˚44´ to 18˚

03´16´´ North latitude and 73˚ 33´ to 75˚ 16´30´´ East longitudes. Total

catchment area covered by the river basin is 15,190 km² with 97 watersheds

and 232 km of the total run in Maharashtra (Diddee, J. et al 2002). It covers

majority portion of Satara, Sangli and Kolhapur districts. The tripartite study

region of three districts is delimited by Raigarh and Pune districts from the

north, Solapur district and part of Karnataka State from east and south,

whereas, from the western boundary there are Sindhudurg and Ratnagiri

districts.

2.3 GEOLOGY AND TOPOGRAPHY

The geological arrangement of the upper Krishna basin is not evenly

distributed but it has slight changes. The upper Krishna basin maximum part

covered by the Deccan trap lava flows of Late Cretaceous to Paleocene age.

The lava pile is classified into three formations.

i) Diveghat Formation

The oldest Diveghat formation comprises 15 flows showing predominantly

mixed lava types. The formation has an exposed thickness varying from 100 to

330 m and exposed along the valleys of Koyana, Yerala, Urmodi, and Krishna

rivers. It also occurs around Wai, Karad, Satara, and west of Tasgaon.

ii) Purandargarh Formation

Purandargarh formation comprises of eight basaltic flows. This formation is

extensively exposed around Vaduj, north and south-east of Koregaon, around

Patan, south-west of Karad, along Koyana river, north and south-west Vita and

western boundary adjoin to Kolhapur district. A mega cryst flow (m4) showing

large plagioclase laths of 1 to 2 cm in a fine-grained ground mass, occurs at top

of Purandargarh formation. This flow has maximum thickness of 30 m and is

noticed throughout the area, characterizing it as a maker horizon between

Purandargarh and Mahabaleshvar formations.

iii) Mahableshwar Formation

Mahabaleshvar formation, the youngest in the lava succession in the

district, comprise of nine flows. Thickness of this formation varies from 350 -

400 m and occurs at the top of isolated hills and hill ranges trending north-west

to south-east. The formation is also exposed north-west of Aundh, around

Mahabaleshvar, west of Satara, south-west of Karad, South-east of Wathar,

east of Bhuinj, around Khanapur and western part adjoin to Satara district.

Dharwar of the Archaean-Palaeo-ptoterzoic occupying a small area in the

southern part of district forms the oldest lithostratisegraphic unit which

comprises meta-graywacke, chlorite-phyllite, quartzesericite schist,

23

metabasalt/metagabro and amphibolites schist which are intruded by granite.

(fig. 2.2)

Slope

Slope map is prepared using SRTM data and ArcGIS software for the

study area. The western part of the region is having steep slope and slope

decrease towards the east. The western ghat region is facing steep slope and

remaining part gentle slope. From the slope of the area we can determine the

surface runoff and soil erosion (fig. 2.4).

Slope Aspect

Aspect is the directional measure of slope in degrees and it ranges from

0 degree at the North, moves clock-wise and end with 360 degrees at the

North. Aspect can be very influencing on temperature. The aspect map is

generated using ArcGIS software and DEM of the area. The aspect of a slope

can make very significant influences on its local climate (microclimate). For

example, because the sun's rays are in the west at the hottest time of day in the

afternoon, in most cases a west-facing slope will be warmer than a sheltered

east-facing slope. In the study region middle part of the basin is flat area and

most of the slope facing towards the eastern side. After that the northward

slope is more (fig. 2.5).

Digital Elevation Model (DEM)

The digital elevation model is 3D representation of the terrain. The

DEM is prepared using ArcGIS software and Shuttle Radar Topography

Mission elevation data (SRTM) which is downloaded from the GLCF website.

The DEM is 3 dimensional representation of the elevation value of the

particular area. The DEM of the Upper Krishna River showing high elevation

western side the gentle slope towards the eastern side. From the analysis of the

DEM people generally predict the elevation of the area. From the digital

elevation model we get the elevation of the area. The study region is having

620 to 880 meters from the mean sea level elevation in most of the parts and

after those 360 to 620 meters. The upper north region is having highest

24

elevation in the study region which is 1140 to 1400 meter from the mean sea

level (fig. 2.6).

Topography is not evenly distributed in study region. Keeping this view

in mind, the study region has been considered by knowing the physiographic

and geological structure. Upper Krishna basin is a part of the Deccan trap of

Maharashtra with an average height of 600 meters from mean sea level.

Generally the study region is having the mountain and hilly ranges in the

western part but the eastern part particularly the river course are adjoining

moderately undulating nature of topography along with river plains of limited

extension.

The western undulating zone of Sahyadri and Mahadeo hills

The study region upper Krishna basin contains two major systems: Sahyadri

range and its offshoots and Mahadeo ranges and its offshoots.

1) Sahyadri Range and its Offshoots

The Sahyadri ranges parallel to the Arabian Sea are stretched right from

the north side of Pratapgarh turning to the east and further it turns to the south

in an irregular line, continues to stretch south of study region. Within the Satara

district from north to south range is known as Pratapgarh, Makarandgad, Jangli

– Jaygad, Bhairavgad. There are five spurs pass east and south-east from the

Sahyadri. From the north these spurs named as the Kamalgad, Vairtgad,

Hatgegad-Arale, Bamnoli-Gheradategads and Bhairvgad- Kandur. In the

extreme south of the Satara district, starting from the main line of the Sayadris

near Bhairvgad about 22.4 km south-west of Patan a great belt of hills stretches

south-east parallel to and a little north of the Warana about 57.6 km to near

Vandur and Vadibhagai 8 km south-west of Shirala, forming with Warana the

boundary between Sangli and Kolhapur district. From this range several spurs

run north-east and east and fill the south-west corner of the district with hills.

Of these spurs there are three chief lines, Gunvantgad about 8 km south-west of

Patan, the divide between the Koyana on the left or north and the Morna on the

right or south; the Kahir-Kirpa spur running east and separating the Morna on

25

the left or north from the Kole or Vang river on the right or south; and the

Kalgaon-Jakinvadi spur running north-east to near Kapil about 4.8 km south of

Karad and separating the Kole river on the left or north-west from the

Nandgaon stream on the right or south-east.

2) Mahadeo Ranges and its Offshoots

The second system of the study region is the Mahadeo system. The

northern boundary of the study region is bounded by the Mahadeo range which

starts from about 16 km north of Mahabaleshvar. This range runs 48 km

towards east and then it turns south-east. Besides many small openings the

Mahadev range is crossed by important passes, the Khambtki, and Tadvala

pass. From the main range of the Mahadev hills are having three spurs stretch

south; the Chandan-Vandan spur, in the west which runs about half across the

district, and the Mahimangad-Panhala spurs further east which stretch right

across the district. In the both the Sahyadris and Mahadev ranges the highest

pick is Mahableshwar and its height is about 1435 m above mean sea level.

About 48 km after leaving the Sahyadris the Mahadev hills keep a height of

about 1219 m above the sea level and about 600 m above plain. The south face

of the Mahadev range falls much more gently to the valley of the Krishna.

Central Plains

This zone stretches from north to south and is parallel to the above

western hilly zone. It lies between the western hilly zone and the eastern

undulating zone. The zone includes eleven tahsils in the central part of the

region. The river Krishna and their tributaries drain this zone forming an

extensive alluvial tract. The average height of this belt is 600 meters. The

medium and deep alluvial soils and moderate leveled land are mostly suitable

for agriculture (Pawar, 1981).

Eastern Upland Zone

Eastern undulating zone of physiography covers area of Koregaon and

Khatav (Satara district), Kavathemahankal, Khanapur and Tasgaon, Miraj, and

Jath (Sangli district) tahsils. The Khanapur plateau has an average height about

26

750 m which lies in the middle-east part. The chief character of this plateau is

in broken form due to the intensive weathering and also the hills are observed

in scattered manor. The rivers of this area are seasonal because of the scarcity

of rainfall. Also this area has fertile soil, if river linkages are developed for

irrigation then available resources will be used fully and got permanent

solution on drought.

2.4 CLIMATE

Climate is the one of the most important geographical factor which

affects on the water availability. The distribution of the rainfall plays

fundamental role in the drought and flood hazards. Temperature, rainfall,

humidity and evaporation play important role in the total runoff, drainage

pattern, water losses. Climate is the key aspect of the physical environment

affecting flood condition in any region. The drought condition depends on the

rainfall intensity. The western part of the upper Krishna basin is located in the

Western Ghats having highest rainfall while eastern part is included in the

drought prone area of the Maharashtra. Due to its climatic condition the study

region expressing flood and droughts are happening similar time in the upper

Krishna basin. The climate in general is cool and healthy in the western parts

and warmer in the eastern part of the study region. The climate of the study

region is characterized by general dryness throughout the year except during

the south-west monsoon season.

2.4.1 Temperature

Prevailing temperature in the region has large variety during the year.

The minimum temperature is recorded in the months of December to February

(winter season). In the month of March to May the maximum temperature

recorded and it is an indicator of hot season. The average annual maximum and

minimum temperature in the study region is 38.2°c and 10°c respectively.

Temperature governs the rate of evaporation, humidity, water requirement to

crops and natural vegetation.

27

Temperature in the region is large verity during the year. In the

western part of the region is cool in the rainy season than winter. The

eastern part feels hot in summer and cools in winter season. So, the range

of temperature is high in eastern part and low region in the western part.

2.4.2 Rainfall

Rainfall is more significant environmental factor which affects on the

flood and drought situation in the study region. Average annual rainfall in the

study region varies from district to district and it decreases from west to east.

In the western part of the region average annual rainfall is more than 2000 mm

and eastern part the rainfall is only about 500 mm.

Distribution of Rainfall

On the rainfall amount and assurance, the basin has been divided into

different zones and these zones are as follows:

i) Zone of High Rainfall (Above 2000 mm)

This rainfall zone includes the western mountain occupied tahsils of the

study region. Due to orographic condition top of the Sahyadri and its adjoining

areas get high rainfall and it is reported from various stations nearly average

annual rainfall range is above 2000 mm. Distribution of rainfall of this category

includes the tahsils, namely Mahabaleshwar (2343.90 mm), Gaganbawada

(5875 mm), Radhanagari (3633 mm) and Chandgad (2742 mm) tahsils which

have more than 2000 mm rainfall. It generally, reveals that rainfall is

decreasing from south to north.

ii) Zone of Moderate Rainfall (1000 to 2000 mm)

The central tahsil of the upper Krishna basin includes in this rainfall

region. Present zone is situated at the foot of the Western Ghats. Present

middle region receives moderate rainfall but there is assurance about the

rainfall. This region extends Wai in north to Chandgad tahsils in south. Present

region receives 1000 to 2500 mm average rainfall per year. The rainfall

intensity is decreased with comparison to west high rainfall zone, but rainfall is

moderately regular.

iii) Zone of Less Rainfall (Less Than 1000 mm)

Eastern part of the upper Krishna basin from the Krishna river to eastern

boundary fall in this region. It receives average annual 500-1000 mm rainfall.

The undulating plateau zone includes Koregaon, Khatav, Khanapur, Kadegaon,

Palus, Miraj, Tasgaon and Kavathemanhkal tahsils. Present zone comes under

the rainfall shadow region. From 2001 to 2011, more than seven years this

zone gets rainfall below the average. In 2003-2004 and 2011 year the rainfall is

below 300 mm. Vast area of this region received below 500 mm rainfall.

30

Therefore, eastern parts continuously suffer from drought hazard. (fig. 2.7 and

2.8).

2.4.3 Rainfall Intensity

Intensity of rainfall is ratio between the sum of rainfall and number of

rainy days in specific period and place. Rainfall intensity affects on the soil

erosion, drainage development, floods and droughts. The rainfall intensity in

the upper Krishna basin varies from place to place. Figure 2.9, 2.10 and table

2.4 shows the rainfall intensity of the study region. On the basis of rainfall

intensity the study region is divided into four categories. Western part, the

tahsils namely Mahabaleshvar Shahuwadi, Radhanagari, Bavada, and

Chandgad revels rainfall intensity is very high and it is more than 20. The

Javali, Patan, Bhudargad, Panhala and Ajara tahsils have rainfall intensity in

between 15 to 20. Maximum part of the study region shows rainfall intensity

between 10 to 15 and it includes Wai, Satara, Karad, Koregaon, Shirala

Walwa, Kavathemanhkal, Jath, Miraj, Hatkanangale and Kagal tahsils.

2.4.4 Evaporation Rate

Evaporation rate of the surface water is important factor in the water

loss and in the respect of water utilization. Evaporation rate varies from place

to place and time to time in the study region. It is observed that there is

positive correlation between the temperature and evaporation in study region.

Evaporation rate is high in the eastern part of the study region that is

Ambavade in Khatav tahsil and Belavade in Patan tahsil. The moderate

evaporation rate in the upper Krishna basin is reported from Gudhe and

Ambale (Patan tahsil) Mhaisal (Miraj), Nadgadwadi (Chandgad), Wadange and

Nitawade (Karveer), Pratryachiwadi (Panhala tahsil), Shivade (Karad tahsil),

Shigaon (Walwa tahsil) and Parali (Satara tahsil) stations. Low evaporation

rate is observed from Sarud (Sahuwadi tahsil), Jambre Umgaon (Chandgad),

Mandukali (Bavada), Ajara Ramtirth (Ajara tahsil), and Tarewadi (Gadhinglaj)

which is useful for low loss of surface water. The sub basin of Yerala and

Agrani have maximum evaporation rate which is greater than the western part

of upper Krishna basin. (Fig. 2.11)

2.4.5 Relative Humidity

The proportion of humidity in the atmosphere air is concerned with the

rainfall. Humidity depends on the surface water availability, forest cover and

irrigated area. The relative humidity in the study region is spatio-temporally

unevenly distributed. Relative humidity is high at Mandukali (Bavada),

2.5 NATURAL DRAINAGE

The upper Krishna basin is endowed with a well developed drainage

system. The entire region is drained by the tributaries of the Krishna river, its

important tributaries are Venna, Urmodi, Tarali, Koyana, Yerala Warana,

Panchaganga, Dudhganga, Vedganga, and Hiranykeshi.

The relief, slope and morphology of the region are depending on the

drainage pattern, drainage density and drainage texture. River linkage is totally

depending on the drainage system of the study region. Hence, the drought and

flood hazards are occurred due to the uneven distribution of drainage in the

upper Krishna basin. The drainage of the study region is fine developed in the

western part as compared to the eastern part.

The Krishna is one of the three great rivers of Southern India. Like the

Godavari and Kaveri it flows across almost the entire breadth of the peninsula

from west to east and falls into the Bay of Bengal. In length it is less than the

Godavari, but its drainage area, including the drainage of its two great

tributaries the Bhima and Tungbhadra are larger than that of either the

Godavari or the Kavari.

i) Krishna

The Krishna rises on the eastern brow of the Mahabaleshvar plateau

6.43 km west of the village of Jor in the extreme west of Wai. The source of

the river is about 1371 m above the sea level at 18° 1´ north latitude and 73°

41´ east longitude. On the plateau of the Mahabaleshvar hill near the source of

the river stands an ancient temple of Mahadev. Inside of the temple is a small

reservoir into which a stream pours out of a stone cow-mouth. This is the

traditional source of the river which Hindus lovingly call Krishnabai, the lady

Krishna.

34

From its source the Krishna runs east for about 24.14 km till it reaches

the Wai. From Wai the course of the river turns south. About 16.09 km from

Wai it receives the Kudali from the right about 3.21 km south of Pachvad in

South Wai. After meeting the Kudali, the river continues to run south through

the Satara sub-division by Nimb and Varuth, and after 24.14 km receives the

Yenna on the right near Mahuli about 4.82 km east of Satara. As the meeting

of the Krishna and Yenna, the place Mahuli is sacred. After meeting the Yenna

the Krishna curves to the South-east and separates Satara from Koregaon for

about 16.09 km till it reaches the border of Karad. In Koregaon, after a course

of 64.37 km, about 1.60 km east of Mangalpur, the Krishna receives the

Vasana from the left, and after a course of about 88.51 km south-west of

Venegaon, it receives the Urmodi from the right. Up to Karad the river runs

south ward. It receives from the right two tributaries, the Tarali near Umbaraj

after a course of about 120 km and Koyana meets at Karad after a course of

104 km. From Karad the Krishna runs south-east up to Bhilavdi (Palus tahsil).

About 10 km south of Bhilavdi it receives the Yerala on the left bank. After

4.82 km, south of Sangli (Haripur) it receives the Warana on the right after a

course of 217 km. After its meeting with the Warana the Krishna continues to

run south-east.

Within the Satara district the channel of the Krishna river is too rocky

2.6 SOILS OF STUDY REGION

Soil is the fundamental aspect of the geographical study. Soil texture,

colour, depth and fertility affect the water utilization for the irrigation purpose.

The degree of reduction, mobility and thickness of regolith affect on the slope

development of the area. The impact of the flood and drought on agricultural

sector is different from soil to soil. Soil texture and structure affect on the

percolation capacity, which affects on the runoff rate of the drainage area.

The origin and the distribution of the soil in the upper Krishna basin are

prejudiced by the climatic and geological condition. The upper Krishna basin

has classified into three rainfall zones on the basis of climatic phenomena. The

western part of hilly region receives high rainfall covered the lateric soils on

the hill tops and reddish in color on the eastern hill slopes. The Krishna, Warna

and lower Panchaganga river valleys of Satara, Sangli and Kolhapur district

41

have deep black cotton soils of alluvial origin. Upper Krishna basin is a part of

‘Deccan Trap’ formulated by the pre-Cambrian-Crystalline rocks which is the

source of the soil variety. The soil types and their distribution in the study

region vary from place to place. The soil types are classified as follows:

Laterite Soils

Laterite soil is continuously distributed in north-south direction in the

Western Ghats and it flanks in the west. This soil is formed on up-ghats in the

western part of the basin because this area receives very high rainfall. Laterite

soils are slightly acidic and usually leach total soluble salts and calcium

carbonate. Their total exchangeable capacity is low and soils are poor in

productivity. Laterite soils are red in colour and are locally named as tambad

mati. Present soil is found on the top and eastern slope of Western Ghat.

Laterite soil occurs mainly in Mahabaleshvar, Wai, Satara, entire Koyana

valley, Shirala, Shahuwadi, Panhala, Karveer, Bavada, Radhanagari,

Bhudargad, and in the western part of Ajara. The red colour of soil formed due

to high content of iron oxides. These soil areas have the high degree of erosion

and leaching. They are clay loam in texture and are rich in nitrogen.

Reddish-brown Soils

Reddish brown soils are found on hill slopes and in undulating areas in

heavy rainfall regions of the upper Krishna basin. This is residual soils and are

usually structure less and sandy loamy in texture. Due to adverse topographical

conditions this soils has limited depth and poor in fertility. Reddish brown soils

straps are found in Karveer, Radhanagari and in some western parts of

Bhudargad and Ajara tahsils.

Deep-Black Soils

In the study region there is regional variation in the distribution of black

soils. The colour of black soil are various from brown to dark black and depth

is also different. On the basis of the soil depth black soils are classified into

two categories, deep black and medium black soils. This soil is derived from

basalt of Deccan trap, and black color derived from hums and clay complex.

42

As per the norms formulated by the I.C.A.R. (1989) the black color is

variously assigned to the presence of titian ferrous magnetite, organic

compound of iron and aluminum accumulated humus and hydrated double iron

and aluminum silicate.

The areas having assured rainfall in the Krishna basin found deep- black

soils. Physical condition of this soil is very good, colour is dark brown, clay

texture and granular to fragment structure. Deep black soil are found near to

river course particularly in mature stage of Krishna, Warna, Koyana and lower

parts of the Panchaganga . From long periods particularly in rainy season flood

water deposited fine sediments on both right and left sides of river course.

Thus, narrow strips have been formed of a deep black who ranges from 6 to 8

meters in depth from surface. Deep black soils are mainly found in the central

part of Wai, Satara, Karad, Walwa, Palus, Miraj, Shirol, Karveer,

Hatkanangale tahsils. The deep black soil has very high water holding

capacity.

Medium Black Soils

The areas of medium black soils cover vast area of the study region

excluding Mahabaleshvar and Bavda tahsils. The tahsils namely Patan, Jaoli,

Shirala, Bhudargad, Panhala, Gadhinglaj observed this type of soils in less

compartment. Present soils are loamy to clay in texture and are suitable for

irrigation crops. The clay content ranges from 55 to 70 per cent and silt from

10 to 20 per cent. The black colour in this soil formed due to the presence of

titan ferrous magnetite iron, black constituents of present rocks and humus

content.

Coarse Shallow Soils

The coarse shallow soil exists mainly in the hill ranges, especially

offshoots of the Shaydari and southern flanks of Mahadeo ranges in the north-

eastern parts. The patches of this soil occur on Khanapur plateau in the east. In

the Khatav, Khanapur, Tasgaon and Kavathemanhkal tahsils, the soil is

43

extremely poor and shallow. The soil is light brown in colour and loamy to

sandy in structure. It contains about 9.30 per cent of calcium carbonate, 8.00

per cent of clay, 18.00 per cent of silt and pH value about 8.55. Due to less

depth and poor texture and loamy to sandy structure the water holding capacity

is very less.

2.7 NATURAL VEGETATION

Natural vegetation is one of the important key aspects of drainage

morphometry, rainfall runoff, soil erosion and flood disaster. The forest cover

delay the rainfall runoff and check the soil erosion rate and it is helpful for

reduction of the flood intensity and increase the ground water level.

Plants provide a protective canopy that lessens the impact of raindrops

on the soil, thereby reducing soil erosion. Roots help to hold the soil in place.

Vegetation provides shade which prevents the soil to become too dry. Thus soil

increases the moisture holding capacity. Transpiration from the forests affects

the relative humidity and cause precipitation in a region. The layer of leaves

that fall around the tree prevents runoff and allows the water to percolate into

the soil, it becomes helpful to increase ground water level. It also plays an

important role in maintaining water cycle of the region. The distribution of

natural vegetation and its types are classified into following categories:

Semi Evergreen Forest

The top of the Sahyadri receive the high rainfall as well cold climatic

condition favorable for semi evergreen forest growth and due to that such belt

is confined this type of forest. The composition of vegetation is as Jambhul,

Anjani, Hirada, Surangi, Panjambhul get mixed up with Pnansi etc. This forest

is mainly confined above the 750 m from MSL. Western Ghat newly has

become the World Heritage due to its vegetation diversity. Western part of

study region particularly Kas plateau, Koyana region, Chandoli, Dajipur,

44

Radhanagari and Amboli etc. and their adjacent areas prevailing this type of

forest.

Mixed Deciduous Forest

Eastern hill slope of Sahyadri and valleys are covered by mixed

deciduous forest. The mixed deciduous forest type is confined on low height

with high rainfall intensity. In this forest Gela, Kunbha, Behada, Ain, Avla,

Bahava, Modi, Dhhaman and Warang etc. are the major species of trees and

Karwand, Rameta, Fhngali and Bhandir, etc. scrubs are observed. Besides this

herbaceous and climber vegetation, variety of grass are grown in this forest

type.

Dry Deciduous Forest

Eastern part of the study region comprises dry deciduous forest type in

Khatav, Khanapur, Kavathemanhkal, Kadegaon, Tasgaon and Miraj tahsils

where the rainfall intensity is very low. Therefore, Apta, Bel, Dhavda, Salai,

Mohi, Biba, Charoli, Palas, Medhashingi, Bartondi, Ain, Hivar, White and red

Kheir, Waghati, Arali, Muradsheng Kari, Gitsaya, Kavli, Kusar, Anantmul,

Ranjui, Utaran, plants are grown in this tahsils.

2.8 AGRO-ECONOMICAL SETUP

Landuse in Study Region

Landuse means utilization of available land for various purposes in

specific time in specific area. Landuse pattern represents the combination of

physical, social and economic factors. Therefore, it is indicator of present

status of socio-economic development of any region. Table 2.5 shows the

tahsil-wise landuse pattern of upper Krishna basin and it reveals the western

and central western tahsils land utilization is better than the eastern and central

eastern tahsils.

Forest land is not equally distributed. It is more confined in western

hilly region, it includes Mahabaleshvar, Jaoli, Bavda, Bhudargad, and

Radhanagari tahsils have more than 30 per cent land under forest because of

more favorable climatic condition. Plain area of Krishna basins of Karad,

45

Miraj, Karveer, Kagal, Shirol, Hatkanangale, Walwa and drought prone area of

Khatav and Kavathemahankal tahsils have very low forest cover.

46

The net sown area in the study region is 60.40 per cent. The western

part of the study region has shown that the net sown area is less than 50 per

cent due to steep slope, hilly land, thin soil, and other adverse condition. In the

Kolhapur district Hatkanangle, Shirol, Gadhinglaj and Kagal tahsils have more

than 80 per cent net sown area. Drought prone tahsils namely Khatav,

Khanapur, K. Mahankal net sown area is more than regional average.

Fallow land is more recorded in Jaoli, Khatav, Mahabaleshvar and

Koregaon, it is more than 10 per cent. Fallow land is more in these tahsils

because of undulating plateau topography and hilly landscape. Cultivable

waste land is highest in western hilly tahsils Jaoli, Patan, Bavada, and

Shahuwadi in between 10.43 to 19.35 per cent. Some urbanized tahsils like

Karveer (11.96 %), Satara (14.83 %), and Miraj (11.78 %) represent high

proportion of area not available for cultivation category.

Satara, Sangli and Kolhapur are leading districts in agriculture sector in

Maharashtra. Average 48.72 per cent (cultivators) and 19.73 per cent

(agriculture labour) of total working population and it is more than 69 per cent.

Banks of Krishna, Koyana, Warna, and Panchaganga have fertile land.

Therefore, agriculture prosperity has taken place in this water shades. Present

area is highly irrigated and supports for intensive agriculture. But agricultural

development and cropping pattern in study region is not evenly developed

because of uneven geographical condition. Eastern part of study region

practices dry farming due to drought prone condition.

Cropping Pattern

Cropping or agricultural enterprise patterns are the extent to which the

arable land under different agricultural activities can be put to use (Singh and

Dhillon, 1982). In most of the situations the physical environment reduces the

choice of the enterprises, either by prohibiting the growth of certain crops

altogether or by reducing their level of their output to an unprofitable degree

(Morgan and Munton, 1971). Cropping pattern is determined by the natural as

well as socio-economic factors. Cropping pattern in study region changes year

to year. In recent years cropping pattern inclined towards cash crops due to

modernization of irrigation means and other technological development.

Cropping patterns show decrease trend in food grains like bajara, jowar and

rice and pulses.

i) Cereals and Pulses

A food crop includes jowar, bajara, wheat, rice and cereals and pulses.

The cultivation of these food grains is regional variation. In the eastern part of

upper Krishna basin Khatav (68.01 %), Koregaon (57.39 %) Kavathemahankal

(69.19 %), Khanapur (52.90 %) tahsil bajara and kharif and rabbi jowar

cultivation is high. Apart from these food crops, cereals cultivation is high in

rain shadow region. But in western high rainfall region, like Chandgad, Ajra,

Patan, Jaoli, Bhudargad and Mahableshwar rice crops are produced.

ii) Sugarcane

Sugarcane is an important cash crop in the study region where total area

under this crop is increasing in irrigated area. Area under sugarcane is more

than 25 per cent in Shirol, Karad, Walwa, Karveer and Bavda tahsils. In

coming years irrigation facilities and assurance of high rate about sugarcane by

sugar industries, the area under sugarcane is increasing. Some command area

of Takari, Arphal irrigation project helps to increase sugarcane cultivation. But

in the eastern tahsils sugarcane cultivation is very low.

iii) Oil Seeds

Oil seeds include groundnut, soybean, sunflower and suffola are the

major crops. This category of crops placed on third rank in study region.

Hatkanangale, Shirol, Gadhinglaj, Walwa, Kagal, Patan and Miraj tahsils have

occupied large area. Groundnut is significant crop in this category and it is

remarkably cultivated in Gadhinglaj tahsil as compared to other tahsils of the

study region. Hilly and drought prone region has shown less land under oil

seeds cultivation.

iv) Other Crops

Fruit and vegetable cultivation is not significant in upper Krishna basin.

Mahabaleshvar tahsil has cultivated strawberry because tourist market is

available in Mahableshwar and Pachgani. Another in Tasgaon and Khanapur

49

tahsil growing grapes cultivation is high and now days grapes cultivation is

increasing in Walwa and Palus tahsil.

Irrigation

Irrigation is key factor of agriculture development. Monsoonal climate is

dominated in study region. Therefore, such climatic condition now a days

becomes a gamble particularly in eastern part of upper Krishna basin. Due to

uneven rainfall and physiography phenomenon irrigation facility is not equally

distributed and developed in study region. Walwa, Karad, Satara, Koregaon,

Miraj, Palus, Kadegaon, Karveer, Kagal, Shirol and Hatkanangale tahsil have

more irrigation facilities through rivers and canals. These tahsils have number

of different levels irrigation projects but the eastern tahsils are very poor in that

respect. The study region avails 25.32 per cent irrigated land out of its total

cultivable area. The means of irrigation wise irrigated area has been reported as

well (36.60 %), river (46.31 %), canal (13.38 %) and other sources of irrigation

occupied 03.69 per cent land.

Industries

Upper Krishna region is one of the industrially leading parts of

Maharashtra state. But its distribution and development is found uneven. For

the better study of industries of the region are broadly categorized as

following:

Agro based Industries

Agriculture is prime activity of study region hence the raw material from

agricultural sector provides concrete platform to agro based industries. In them

sugar industry, cotton industries and dairy farming and processing plants etc.

i) Sugar Industry

The upper Krishna basin is ideal for sugar industry due to its raw material

like sugarcane production; hence it has become the backbone of agricultural

development in Satara, Sangli and Kolhapur district. In upper Krishna basin

there are 39 sugar industries and out of them more than 90 per cent industries

50

are run by co-operative sector. Sugar industries of drought prone area have

faced one major problem and that is deficiency of raw material. So, some sugar

industries are at closing stage. Karad, Walwa, Miraj, Hatkanangale, Karveer,

Kagal, Chandgad tahsils have each 03 sugar factories. But Mahableshwar,

Khatav and Radhanagari tahsils have not any sugar industry.

ii) Textile Mills

Textile is another second largest agro based industry developed in the

study region. There are 37 co-operative textile industries in study region.

Ichalkaranji is a Manchester of Maharashtra (Hatkanangale tahsil), there are

number of textiles, spinning and weaving mills. In Kolhapur, Sangli and Satara

districts have co-operative textile parks. Vita, Kadegaon, Palus, Tasgaon and

Islampur are main centers of co-operative textile parks.

iii) Dairy Farming

Dairy farming is main parallel sub occupation in upper Krishna basin.

Now days, dairy farming activity has become a daily economical earning

source. Upper Krishna basin has 6004 co-operative milk collection centers. In

this sector Gokul, Warana, Rajarambapu, Hutatma and Koyana Milk Co-

operative Sangh are playing dominant role and increasing their collection as

well as milk products. Besides co-operative sectors there are few private milk

collection centres like Chitale and Thote are leading in milk process industries.

Milk production of upper Krishna basin in 2010-2011 is 115.90 billion

metric tons. Now a days the numbers of milching animals are increased.

According to animal census of 2003 there are 875838 buffalos and 264184

cows in all over upper Krishna basin. Milching animals are increased in current

year and farmers are prepared cross breeding buffalo and cows for present

production.

2.9 TRANSPORT AND COMMUNICATION

Transport and communication is an indicator of regional development.

Upper Krishna basin has well developed transportation and communication

network. In the Krishna basin the network of roads and railways are well

51

developed. But areal developments of road and railway routes are not equally

distributed. Western part of districts has low density of road and absence of

railway network due to its topography. Total road length in upper Krishna

basin is 22066.76 km and length of railway route is confined in study region is

334.51 km.

There were 1454 post offices in 2010-2011 and numbers of telephones

in same period were 348453 (Socio-economic Abstract 2011). Apart from

other means of communication mobile phones facility is increased day by day

and it is reached at door to door. All urbanized and industrial area namely

Satara, Karad, Karveer, Hatkanangale, Miraj have very good communication

means.

2.10 POPULATION CHARACTERISTICS

Out of all resources human resource is most important because man is

creator of all resources. With the help of knowledge and technology man can

overcome on the natural barriers. Total population of upper Krishna basin is

8157383. Population distribution in study region is uneven. High population

concentration is located in Karveer, Miraj, Satara, Walwa and Shirol tahsil

because of high fertile and irrigated land and urbanization. Very low population

distribution is found in Mahableshwar, Ajara, Jaoli, Bhudargad, Shirala and

Shahuwadi due to high altitude, steep slopes, and hilly region.

Kavathemahankal tahsil population distribution is low because of frequent

drought condition.

Population density is the indicator of development. Average population

density in upper Krishna basin is 250. But urbanized and irrigated Miraj,

Shirol, Karad, Palus, Walwa, Satara and Karad tahsil population density is

more than average density. And western hilly region Bavada, Shahuwadi,

Chandgad, Radhanagari, Bhudargad and Ajra tahsils comprise low density than

average. The upper Krishna basin is predominantly rural in characteristic as it

is reveled from that out of 29 tahsils, 8 tahsils are purely rural in nature and

remaining tahsils have low per cent of urban population. Urban population

52

constitutes 16.25 per cent in study region. There is high urban population in

Karveer, Hatkanangale, Shirol, Satara, Mahableshwar, Kagal and Miraj tahsil

because of developed agriculture, industrialization and tourism.
