Study Notes

Land Use Categories in Nepal

Total land area: 15.49 million hectares, exceeding 100% due to overlapping categories.
Forests cover 5.96 million hectares, comprising 40.36% of total land.
Other wooded lands amount to 0.64 million hectares (4.38%).
Grassland totals 1.77 million hectares (12%).
Agricultural land encompasses 3.09 million hectares (21%).
Non-cultivated land accounts for 1.03 million hectares (7%).
Water bodies cover 0.38 million hectares (2.6%).
Urban and industrial areas occupy 2.62 million hectares (17.8%).

Ecosystem Diversity in Nepal

Middle Mountains hold 53 ecosystems (44%).
Other significant zones include High Mountains (38 ecosystems, 32.2%) and Terai (12 ecosystems, 10.2%).
Siwalik region features 14 ecosystems (11.9%).

Concept of Agroforestry

Agroforestry integrates food crops, trees, and animals, nurturing a sustainable environment.
Historical practice with roots in ancient agriculture by notable figures like Maharishi Kashyap, emphasizing tree planting on various land types.
Contemporary necessity arises from dwindling forest resources, leading to increased prices for wood-related products.
Farmers increasingly adopt agroforestry to supplement traditional agriculture.

Social forestry focuses on community benefits, including fuel wood and timber supplies for local populations.
Agroforestry is a sustainable method maximizing productivity through integral use of crops and trees.
Social forestry enhances forest areas, whereas agroforestry promotes self-sufficiency through diverse land management.
Key practices include planting trees on community lands, improving rural livelihoods.

Scope and Benefits of Agroforestry

Offers solutions for ecological issues, fuel shortages, unemployment, and meeting population demands.
Suitable for various marginal lands, enhancing land use efficiency through multi-use systems.
Encourages employment opportunities and provides materials for local industries.
Enhances soil and water conservation, improves ecosystem balance, and addresses fodder and fuel shortages.

Challenges in Agroforestry

Complexity arises from diverse farming needs, complicating machinery use and risking crop damage.
Labor intensity increases and migrant labor losses challenge system implementation in Terai and mid-hills.
Limited technical knowledge and resources restrain effective agroforestry management.
There’s an urgent need for improved education and capacity building in agroforestry among farmers.

Tree-Crop Interactions in Agroforestry

Defined interactions between trees and crops affect resource utilization and agricultural productivity.
Quantification of interactions reflects positive soil impact versus competition for growth resources.
Complementary interactions stimulate mutual growth benefits, while supplementary interactions enhance production without harming either component.
Efficient nutrient cycling and microclimate improvement are key outcomes of these interactions.
