The earth, revered for generations as parallel to the deity, is being, unfortunately, viewed as an economic commodity worth destroying for (as in the above quote) to promote selfish and unscrupulous interests of mankind. Not surprising, Land degradation has turned to be a menace calling for immediate attention.

Land degradation is the process in which the value of biophysical environment is affected by one or more combination of human-induced processes acting upon the land.

The life on the mother-earth is sustained by the land, the food and other products it bestows upon the humanity. The quality of land is, thus, critical. Quality of land is given by the nutrients inherent in it, which sustain plant life. These nutrients are regenerated by the land itself. However, indiscriminate use of the land has not provided it the required time to do so. This causes land degradation. The problem is compounded by overgrazing and the like anthropogenic factors. The ever increasing demand for land products, thanks to increasing population and consumerism coupled with the finite nature of the land calls for prudent and frugal use of land. This prudent use entails rehabilitating the degraded land. To elaborate, let us first look at the causes and then march to explore remedies.

Degradation is a global problem, largely related to agricultural use. The causes are land clearance (deforestation); poor farming practices; overgrazing; over drafting; urban sprawl; commercial development; soil contamination; vehicle off-raiding; quarrying of sand, stone, ores, minerals; naked soil being harvested by heavy equipment; monoculture; dumping of non-biodegradable trash; shifting cultivation etc. It is contended that natural hazards are exception as causes of land degradation. Nevertheless, given the unscrupulous acts of the mankind intensifying the probability of occurrence and severity of natural hazards, even natural hazards may also be factored in as degrading the land.

These inevitable causes result in several effects but the most threatening of them are accelerated soil erosion by wind and water; soil alkalization causing poor soil, low in fertility, swelling of soil etc., which are difficult to clarify; soil solemnization causing super saturation of soil leading to low leaching power; water logging-water table of groundwater is too high preventing leaching process and entry of air; destruction of soil structure including the loss of organic matter etc.,

Finally, all these effects reach low yielding capacity of the soil.

Given the gravity of the problem of land degradation, the steps for the rehabilitation of those degraded lands is of urgent need. The process of breathing life into degraded land is termed as Land Rehabilitation.

Land rehabilitation is the process of retuning the land in a given area to some degree of its former state after some process has resulted in its damage. In most cases, the land cannot be returned to its natural state but the unproductive land can be improved to some extent. Land Rehabilitation normally takes place in two major ways.

Natural Regeneration

Natural regeneration involves deliberate management of the land in such a way as to re-establish a healthy ecosystem

Assisted Natural Regeneration

Assisted Natural Regeneration is regeneration by assisting the natural process to regenerate itself. Note that in natural regeneration human intervention is minimal or even nil, but under this approach human intervention induces natural processes that regenerate. Important techniques under this approach may be explained as below:

  • Enrichment planting is a process of planting valuable species in degraded forests without the elimination of the species already present;
  • Early firing is burning the old, dry patches of grass at the undergrowth of dry season;
  • Plantation involves planting trees and shrubs as mixed species on degraded land;
  • The use of agro forestry method.

Supportive Activities

Land rehabilitation is broad enough to include in its fold all those activities which indirectly (direct rehabilitation techniques are explained above) regenerate the quality of soil; those activities which prevent the causes of land degradation and those acts that support the machinery to materialize the land rehabilitation programs. Following are a few such steps:

  • Terrace farming, mulching, contour bonding be encouraged.
  • The government should reduce subsidy to chemical fertilizers and at the same time incentivize the use of organic manure.
  • Better farming practices like crop rotation; crop spacing and mixed farming should be encouraged.
  • Moisture conservation and water harvesting measures must be promoted.
  • The governmental schemes for the rehabilitation of degraded lands are mostly spread across the Ministries of Agriculture and Rural Development. The different guidelines from different ministries cause confusion to the officials who implement it.  So an integrated approach is needed.
  • Community participation in the endeavors to rehabilitate degraded lands should be adopted.
  • Local NGOS, farmers’ associations and local cooperative societies can be made nodal agencies for the implementation of rehabilitation of degraded land in local area.
  • Afforestation, Social forestry would act an effective obstacle to soil erosion. As a corollary, they improve the fertility of soil.
  • The degraded waste land must be used to start industries, carry out mining and build commercial complexes since agriculture is an unviable option on such lands. Carrying out non-agriculture activities on degraded land would save the fertile agricultural land from being diverted.
  • Cultivation of bio-fuel producing plants and fuel trees/crops should be encouraged in the degraded and wastelands.
  • A national level awareness campaign to educate farmers about better farming practices that would enrich soil fertility should be implemented. This awareness campaign should include posters, short-movies and crisp lectures during the periodic meeting of milk cooperative societies, panchayat meetings and other places where farmers assemble.
  • Soil pollution is a grave threat to soil fertility. Scientific approaches like Bioremediation (usage of microbes to treat pollutants) should be implemented. A few such techniques include land farming (mixing the contaminated soils with normal soil and tilling into earth), bio augmentation (introduction of genetically variant microbes into contaminated soil to reduce contamination).

In a nutshell, encouragement of better farming practices backed by policy actions could rehabilitate degraded land.

Therefore, the land is misused by both illiterate and literate and its effect is felt by both of them but, it is up to every literate to make best use of his education and knowledge by not defiling it and also educating the illiterate about degradation. Every literate should think of delving the deliberate defiled lands…

  1. 1. Analyze the efficacy of ‘top-down’ approach as a tool to curb land degradation.

    Since the beginning days of centralized economic planning in our country (beginning of 5 year plans), we have basically adopted ‘top-down’ approach where the instructions and guidelines flows from top – union level to state level and from it to district and taluka level. This approach had given some benefits with respect to industrialization, mineral resource utilization and establishing large public sector but failed to given benefits at the most basic level with large proliferation and inefficiency. This approach has resulted in ignorance of local issues, problems, and variations and hence resulted in ‘anemia’ at extremes with various regional imbalances, problems, environmental degradation, and violation of rights of the people.

    For land degradation we need ‘bottom-up’ approach, as local agro-climatic conditions are not same in our vast country where soil, moisture, weather conditions etc vary significantly – for example rice cultivation in Haryana is major cause of land desertification while it is main crop in eastern India. ‘Top-down’ approach ignores these variations and tends to be over-generalized. With 73rd and 74th amendment, we should enhance participation of local self-government institutions like panchayats to come up with plans about what crops should be cultivated in their area in a eco-friendly and sustainable manner and what assistance is required to do so. They should be made aware about eco-sensitivity and environmental issues and also their traditional knowledge should be harnessed. Therefore there is no wonder that planning commission has recognized that “there is imperative need to give enough flexibility to states in executing the plan.”

    2. Critically analyze the current patterns and future prospects for significant agricultural land improvement to compensate for land degradation

    Land degradation is a serious problem considering the future food security issue, rising population which would be more than 9 billion by 2050 and need of land for various developmental needs – industries, mining, power projects etc. On top of that we also can not ignore the need of forests in view of global warming. Therefore there is need to reclaim the wastelands, improve the existing degraded land and use current usable land in sustainable land.

    Land improvement means enhancing value of the land making it more usable and in current scenario it should be sustainable also. It includes,
    • Hydrological improvement (drainage, irrigation, land leveling, water harvesting, proper leaching, landslide and flood control) – floods and improper drainage is major reason for soil erosion.
    • Soil improvements (included both organic and inorganic methods to maintain balance of nutrition)
    • Soil erosion control/soil management – contour making, furrow bed techniques etc, techniques for decontamination and combating desertification (by adding gypsum in highly saline land for example)
    • Afforestation – as a mean for both water conservation and land protection against erosion.

    We need innovations in improvement techniques which can reclaim wastelands and degraded land by improving it for forestation, developing natural vegetation at least if not for agriculture so that we compensate for land degradation due to intensive agriculture. For this use of microbes, modern bio-technology can help a lot and may be critical in future land improvement techniques.

    In recent times land reclamation or land fill (from sea, water bodies) is being used (in Netherland, Ireland, Russia, Hong Kong, Dubai) which is detrimental to environment as these areas are susceptible to land liquefaction and tectonic changes, moreover they destroy water based eco-system. Hence there is need to restrict such methods.

    Therefore not all land improvement methods are environmental friendly and can not be one-to-one substitute for land degradation.

    3. Bring out a model for enlisting community participation in land rehabilitation projects.

    Community participation is must in land rehabilitation projects because,

    • It needs continuous monitoring for long time period which can be ensured by local community only
    • It needs coordinated effort from various departments, institutions (agriculture department, water resource department, ICRA etc)
    • It is the community which will benefit from such projects
    • To make sure efficient utilization of resources, ensure transparency and prevent corruption

    A model for enlisting community participation

    • Local community must be first made aware about the dangers of degradation and environmental impact of it – long term and short term – with modern means of communication – internet, case studies, short movies etc.
    • Listing of local varieties, bio-diversity should be made and local traditional knowledge should be discussed and documented.
    • Based on local agro-climatic conditions and need for environmental friendly methods, crops allowed to cultivate in the area should be listed and plan for land improvement methods should be made. Demands of subsidy, assistance, irrigation projects, asset creation etc can be done at this stage.
    • Plan for land rehabilitation should be made for already degraded land with listing of activities and time bound execution plan. Scientific inputs from local agricultural research center should be sought.
    • These plans should be integrated with panchayat plan and with district plan.
    • Social audit of the plan at every quarter should be done. Developed degraded land should be declared community’s property with its produce available to all people in equitable manner with preference to women and poor people.

    4. Do you think that land rehabilitation contribute to sustainable development? How?

    Land rehabilitation can contribute to sustainable development because it may be used a reserved forest after developing a natural eco-system in it. It can provide minor forest produces to local community like honey, fire wood etc. It can be substitute for land degradation to an extent. It can be used for developing water tanks, water harvesting projects, industries at village level such as – sugar industry, food processing centers, cold storages etc.

  2. hi gaurav
