Sustainable Land Management

Geography › Agriculture and Crop Geography · Topic 11.3

Sustainable land management (SLM) is the use of land resources, including soil, water, animals and plants, to meet human needs while keeping their long-term productive capacity and ecological functions. Its practices include conservation agriculture, crop rotation, agroforestry, soil and water conservation, integrated watershed management, rotational grazing, organic and natural farming and restoration of degraded land. SLM supports the goal of land degradation neutrality and is promoted by the UN Convention to Combat Desertification, the FAO and the World Overview of Conservation Approaches and Technologies (WOCAT).

Where Does It Fit?

This topic follows the topic on land degradation and gives the answer, which is to manage land so that its productive capacity is kept. It links the earlier topics on soil and forest conservation to farming practice, which the following topics describe. Previous topic: Causes and Impact of Land Degradation and Steps Taken by the Government of India. Next topic: Performance of the Agriculture Sector and Types of Farming.

What Are the Principles of Sustainable Land Management?

Keep the soil covered: use crop residue, cover crops and mulch to limit erosion and keep moisture.
Disturb the soil less: reduced or zero tillage to retain structure and organic matter.
Diversify: rotation, intercropping and mixed systems with trees, which break pest cycles and use soil layers differently.
Manage water: harvest rain, increase infiltration and use water efficiently.
Match use to capability: farm the arable lands and keep steep or fragile land under tree or grass cover, as in Land Use and Land Capability Classification.
Involve people: secure land rights, local knowledge and community institutions.
Integrate: manage whole landscapes such as watersheds, balancing production, water and nature.

Which Practices Are Used?

Practice	Description	Benefit
Conservation agriculture	Minimum tillage, permanent soil cover and crop rotation	Saves water, fuel and labour; builds organic matter. Zero-till wheat in the Indo-Gangetic plain is an example
Integrated watershed management	Treating the catchment from ridge to valley with bunds, trenches, check dams, plantations and farm ponds	Recharges groundwater, reduces runoff and erosion; the Hiware Bazar and Ralegan Siddhi villages of Maharashtra are known examples
Agroforestry	Trees combined with crops or livestock, as in Types of Forestry: Social Forestry, Agro-Forestry, Miyawaki Method	Income, shade, nutrient cycling, carbon storage
Terracing and contour farming	Farming across the slope on steps or along contours	Controls erosion in hills
Rotational grazing and pasture management	Moving livestock between paddocks to rest the grass	Prevents overgrazing
Organic and natural farming	Use of manure, compost and bio-inputs; the National Mission on Natural Farming (2024)	Improves soil health and lowers chemical use
Restoration	Reclaiming ravines, saline lands and mined areas with trees and grasses	Returns degraded land to use, as in Causes and Impact of Land Degradation and Steps Taken by the Government of India

What Are the Frameworks and Challenges?

Global: the UNCCD promotes SLM and land degradation neutrality; the FAO has guidelines; WOCAT collects and shares documented practices. SDG 15.3 aims for a land-degradation-neutral world by 2030.
India: watershed development, PMKSY, National Mission for Sustainable Agriculture, MGNREGS works on water and soil conservation, and the Bonn Challenge pledge, as in Causes and Impact of Land Degradation and Steps Taken by the Government of India.
Benefits: higher and more stable yields, lower input costs, resilience to drought and climate change, carbon storage and cleaner water.
Challenges: small and fragmented holdings, insecure tenure on leased land, upfront costs, lack of knowledge, subsidies that favour chemical inputs and water-intensive crops, and difficulty in measuring benefits.
Way forward: reform subsidies to reward good practice, payments for ecosystem services, extension services, and farmer producer organisations to manage land collectively.

Evidence shows that SLM pays in the long run: zero-till wheat saves several thousand rupees per hectare on fuel and labour and can cut water use, watershed villages have recorded higher groundwater levels and crop yields, and agroforestry adds income from timber and fruit. But benefits come slowly while costs come early, which is why government support, credit and extension are needed in the first years. Measuring results with soil carbon tests and satellite data makes it easier to reward farmers fairly. As an analytical point, SLM is less a single technology than a way of managing land as a whole, with farmers, who bear the cost, receiving a fair share of the benefits. The role of climate change is taken up in Impact of Climate Change on Agriculture and Sustainable Agriculture Practices.

Frequently Asked Questions

What is sustainable land management?

Sustainable land management is the use of land, soil, water, plants and animals to meet human needs while keeping their long-term productive capacity and ecological functions. It combines practices such as conservation agriculture, agroforestry and watershed management, and it supports the goal of land degradation neutrality.

What is conservation agriculture?

Conservation agriculture is a farming approach based on three principles: minimal disturbance of the soil through reduced or zero tillage, permanent cover of the soil with crop residue or cover crops, and diversification through crop rotation. It protects soil, saves water and fuel and builds organic matter.

What is watershed management?

Watershed management is the treatment of a whole catchment area, from the ridge to the valley, with measures such as contour bunds, trenches, check dams, farm ponds and plantations, to conserve soil and water. In India it is done under schemes such as the PMKSY watershed component, with villagers taking part.

What are the barriers to sustainable land management?

The barriers include small and fragmented holdings, insecure tenure for tenant farmers, initial costs, lack of knowledge and extension, subsidies that favour chemical fertilisers and water-intensive crops, and weak markets for sustainably produced goods. Overcoming them needs incentives, rights and farmer organisations.

What does SDG 15.3 aim for?

Sustainable Development Goal target 15.3 aims, by 2030, to combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land-degradation-neutral world. It is the basis of the land degradation neutrality goal promoted by the UNCCD.

It treats the whole catchment.

3 SDG 15.3 relates to land degradation neutrality.
