Social Forestry
REGION | DISTRIBUTION | CLIMATE | VEGETATION | HUMAN RESPONSE |
1. Hot wet equatorial climate | 5° To 10° N&S of Equator, Lowlands of Amazon, Congo Malaysia and East Indies | Great uniformity in Temperature through out the year No winter Almost daily precipitation in the afternoon. High Relative Humidity (7.80%) | Evergreen trees in three distiner layers, Called ‘Selvas’ in Amazon Basin, Multiple species, no pure strands, Shifting cultivation leads to growth of secondary forest. | Excess heat and high humidity leads to serious physical and mental handicaps. Jungle hinders the development and maintenance of tropical soil Commercial extraction of timber difficult and livestock farming handicapped due to absence of meadow grass. |
2. Tropical monsoon and tropi- cal marine Climates | Indian Sub continent, South East Asia, South China and Northern Australia
2. Hot dry season in Summer when temperature is high. 3. Rainy season when the south-west monsoon bursts
| There are three dis- tiner season:- I Cold dry season during N.E. monsoon when there is tittle rain. | Normally deciduous forest in pure stand especially of leak sal. Savanna vegetation in dry months. | Areas of high density of population especially in the major river valleys Wet paddy cultivation is the major primary activity where rainfall is above 100 cm per annum. Low land cash crops such as jute, sugar, cotton are also grown. High land plantation crop-coffee, tea i umbering in teak areas; shifting cultivation in higher areas. |
3.Savanna or Sudan climate | Confined to tropics Sudan Southern Africa. North of 23°S | An alternate hot rainy season and cool dry season. Extreme diurnal range of temerature | Tall grass and short trees; deciduous in nature, local names 1 lanos-Orinico Basin Campos-Brazil Highland | Home of wild animals and cattle pastoralists such as Masai of East African Plateau or settled cultiva- tion like the Hausa of northern Nigeria. Region has great prospect as a cattle region if the problem of water and tsetse fly are controlled. |
4. Hot desert and mid-latitude desert
| Called Trade Wind Deserts. Located on western coasts of continents between lat 15°.30° N & S | Aridity of deserts is high. High diurnal range of temerature. Relative humidity is low. | Dominated by Xero phytic plants. Oasis have date palms, salinity of soil high. | Desert inhabitants may be groped as:-
2) Nomadic herdsmen- Bedouin of Arabia. Oil is the major source of revenue. (3) Caravan traders- Travelling merchants are source of revenue. (4) Settled cultivators in river valleys of Nile. (5) Minning settlers-For gold.. copper and diamond in Kalashari & Australian
|
5. Warm termperature western margin (mediterran- cean climate) |
Central Chile, Cali fornia, S.W. tip of AfricaSouthern Australia, S.W. Australia
| Caused due to shifting of wind belts. A dry warm summer with off shore trades. Concen- trations of rainfall in winter. Bright sunny weather with hot dry summer and wet mild winter local winds.
| Absence of shade evergreen forest bushes and shrubs. Grassland not good
| Desert called the “Cradle of world civilization.” Fruit cultivation, cereal growing, wine making and agro-indistires, orchard farming, crop cultivation, vine production are major activity. |
6.Temperature continental (Steppe) climate | Interior of the continents in the Dry Westerly Wind belt. | Continental with extermes of temper- ature. Annual range of temperature high Rainfall is light with distinet summer maximum | Temperate - Grassland
| Though dominated by nomadic and semi-noma- dic and semi nomadic people, these areas are the ‘Granaries of the world’. Important econo- mic activity include nomadic herding. extensive cultivation, pastoral farming |
7.Warm termperature eastern margin (China Types Climate | South Eastern USA bordering the Gulf of Mexico Parana- Uruguay Basin Natal-South Africa New South Wales Eastern China | Warm moist summer and a cool, dry winter strongly modified by maritime influence. | Low land have both evergreen broad leaved and deciduous forest highland have conifers. | One of the most intensi- vely tilled parks of the earth. In China there is rice covering area, in USA the area is domi-nated by corn and cotton belts. Tobacoo is also grown Dairying in south West Australia. |
8.Cool temperature Western margin | Britain, North Western Europe, British Colum- bia. Southern Chile, Tasmania and New Zealand | Low annual Range of temperature with mild winters because of maritime influence. | Deciduous forest with trees shedding leaves in cold seasons. Pure stands. | Most developed region of the world. Market garde-ning, mixed farming, sheep rearing are important activities Highly industrizlized and urbanized region. |
9. Cool temperature western mar-gin (British-type) climate | Only in Northern Hemisphere in the Siberian region, and North America. | Bitterly cold winter of long duration and cool brief summer. Precipitation well summer maximum | Conifers in pare stands. Richest source of soft wood. Forest are of moderate density with little undergrowth. | Major economic activity include trapping of fur animals, lumbering. There is little agriculture. |
10. Cool temperature eastern margin. | Eastern Canada N.E. USA, North China, Korea, North Japan. | Cold dry winters and warm wets summers. Rainfall has a distinet summer maximum | Cool temperate forest with coniferous, South of 50° N conifers give way to deciduous. | Agriculture and fishing are major economic activities Fishing is a major industry. |
11. Polar climate | North of Arctic Circle in Northern Hemisphere. | Temperature mostly below freezing point Snow is main form of precipitation. | Hardy grass and reindeer Moss shunted growth due to defici-ency of heat and poordrainage | Human activities largely confined to coast. Eskimos live in Greenland. northern Canada and Alaska. |
