TEXTUAL QUESTION AND ANSWERS
Q.1. What is meant by agriculture? Mention briefly the factors influencing agriculture?
Ans: Agriculture is the art and science of cultivating the soil, growing crops, and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. Agriculture provides most of the world’s food and fabrics.
The factors influencing agriculture are:
1. Soil: For agriculture to develop, the soil needs to have depth as well as nutrients. Texture of soil is important as it determines if the soil can hold water or not. Sandy soil is not fit for agriculture as it does not retain water. On the other hand, loam soils are good for agriculture. Agriculture develops in fertile land that is rich in organic matter.
2. Climate: Sunshine, humidity and rainfall are important factors that influence agriculture. Agriculture doesn’t develop in extreme climates. It is difficult to grow crops in areas that have temperatures beyond 45 degree celsius or below 1 degree celsius.
3. Topography: Relief of the land and terrain influence agriculture as they determine level of soil erosion, ease in tilling and mechanization of farms. Farms mostly develop in plains and valleys as the level of soil erosion is less. On the mountain, the hill has to be cut into terraces to practice farming. This makes tilling of the land as well as use of machinery difficult.
4. Human factors: Agriculture is also influenced by human factors like market, labour and political aid. If there is availability of cheap labour, then labour intensive crops are grown. Places near markets grow perishable goods. Government aid in agriculture is an important factor too. In the 1960’s the government aided Green Revolution in India changed the agricultural scene of states like Punjab and Haryana.
Q.2. Explain why agriculture practice is not similar everywhere in the world?
Ans: Agriculture practice is not similar everywhere in the world because in meghalaya there was roof corp agriculture in madhya pradesh do strip farming and in Uttarakhand their were terrace cultivation.
Q.3. Classify agriculture and give the basis of your classification.

Q.4. What is permanent agriculture? Discuss briefly its characteristics.
Ans: Permanent agriculture is defined as an integrated and progressive production system inspired by natural ecosystems. Permanent agriculture is mainly based on the use and the promotion of biodiversity around and on the farm.
Here are some characteristics of permanent agriculture:
(a) Perennial Crops: Permanent agriculture involves the cultivation of perennial crops, such as fruit trees (e.g., apple, mango, citrus), nut trees (e.g., almond, walnut), vineyards (for grapes), and perennial grasses (e.g., bamboo). These crops have longer life cycles and can produce yields for many years.
(b) Deep Root Systems: Perennial plants often have deep root systems that help them access water and nutrients from deeper soil layers. This characteristic makes them more resilient during droughts and adverse weather conditions.
(c) Soil Conservation: Perennial crops play a vital role in soil conservation. Their extensive root systems help prevent soil erosion by stabilizing the soil structure. This is particularly important in areas prone to erosion and desertification.
(d) Biodiversity: Permanent agriculture systems often incorporate a variety of perennial crops, creating diverse ecosystems. This biodiversity supports a range of wildlife and beneficial insects, contributing to overall ecosystem health.
(e) Carbon Sequestration: Perennial plants capture and store carbon dioxide from the atmosphere, aiding in carbon sequestration. This is crucial for mitigating climate change by reducing greenhouse gas concentrations in the atmosphere.
(f) Reduced Chemical Inputs: Perennial crops generally require fewer chemical inputs such as pesticides and fertilizers compared to annual crops. Their long life spans and natural resistance to pests and diseases contribute to reduced dependency on synthetic chemicals.
(g) Sustainable Water Usage: Perennial crops, particularly those adapted to specific regions, are often better suited to the natural water availability of the area. They can be selected based on their drought tolerance, reducing the need for excessive irrigation and promoting sustainable water usage.
(h) Agroforestry Practices: Permanent agriculture systems often integrate trees and shrubs with other crops, creating agroforestry systems. Agroforestry combines agricultural and forestry practices, providing multiple benefits such as improved soil fertility, increased biodiversity, and enhanced ecosystem resilience.
(i) Long-Term Economic Stability: Once established, perennial crops provide a stable source of income for farmers over several years. This long-term economic stability can enhance the livelihoods of farming communities.
(j) Ecosystem Services: Perennial agriculture systems provide various ecosystem services, including water purification, pollination, and habitat for wildlife. These services contribute to the overall well-being of the environment and surrounding communities.
Q.5. Give a brief outline of shifting cultivation. How these types of agriculture regards the environment.
Ans: Shifting cultivation, also known as slash-and-burn agriculture, is an agricultural practice in which land is cleared, cultivated, and then abandoned for a period of time to allow natural vegetation to grow back.
Here’s a brief outline of shifting cultivation:
(a) Clearing: Forest or vegetation is cut down and burned, releasing nutrients into the soil. The ashes provide a source of nutrients for crops.
(b) Cultivation: Crops are planted in the cleared area and cultivated until the soil fertility declines, typically for a few years.
(c) Abandonment: After a few years, the plot is abandoned, and the forest is allowed to regrow. The farmer moves to a new plot and repeats the process.
(d) Rotational Cycle: The farmer may return to the original plot after several years once the soil fertility has been naturally restored.
Environmental Impact of Shifting Cultivation:
(a) Biodiversity Loss: The initial clearing of forests results in habitat loss and reduces biodiversity. The regrowth period allows biodiversity to recover to some extent.
(b) Carbon Emissions: Burning forests for clearing releases carbon dioxide into the atmosphere, contributing to climate change. However, during the fallow period, the regrowing forest sequesters carbon, offsetting some of these emissions.
(c) Soil Erosion: Without the forest cover, soil is susceptible to erosion, especially in regions with heavy rainfall. This erosion can lead to loss of fertile topsoil and degradation of land.
(d) Water Quality: Runoff from cleared areas can pollute nearby water bodies with sediment and agrochemicals used in cultivation.
Q.6. Present a comparative picture of large scale and small scale agriculture?
Ans: Agricultural productivity is variously measured, and large-scale farming is often less efficient than small sustainable farms.
A comparative picture of large-scale and small-scale agriculture are:
Q.7. What do you mean by plantation farming? Discuss its characteristic?
Ans: Plantation farming is the practice of clearing a large parcel of forest land and planting large quantities of desired crops on the cleared land. This type of cultivation helps in increasing the desired yield and makes the cultivation easier to control.
The main characteristic of plantation agriculture are:
(a) A signal crop is grown over a large area.
(b) It is capital intensive and done with migrant labour.
(c) All produce is used as raw material in industries such as tea coffee rubber sugarcane banana etc.
(d) Plantation has an interface of agriculture and industry both.
Q.8. Describe briefly the relationship between urbanisation and market gardening.
Ans: Urbanization has been underpinned by the rapid growth in the world economy and in the proportion of gross world product and of workers in industrial and service enterprises. Globally, agriculture has met the demands from this rapidly growing urban population, including food that is more energy-, land-, water- and greenhouse gas emission-intensive. But hundreds of millions of urban dwellers suffer under-nutrition. So the key issues with regard to agriculture and urbanization are whether the growing and changing demands for agricultural products from growing urban populations can be sustained while at the same time underpinning agricultural prosperity and reducing rural and urban poverty.
This development in agriculture is known as market gardening. This trend is fast catching up in India due to expansion of urbanization in the country and villages and towns are getting interlink due to the impact of globalisation.
