4. Drivers of Soil Erosion
• Technically, sloping lands are considered to be suitable for non-arable agriculture. But most farmlands in the hills are under arable agriculture(mostly food crop).
• The arable agriculture, which requires regular hoeing/plowing of farm lands on steep slopes, is attributed as the primary cause of soil erosion.
• Though farmers had made their utmost efforts to control soil erosion, example: terraces, they could not control it effectively due to hoeing/plowing of farmlands on steep slopes.
• Traditionally adopted for food security in an economically isolated situation, the arable agriculture still dominates the agricultural land use in the Hills.

Agricultural Land Use in the Hills (in 000 Ha)
1Other low erosion prone crops include tea, coffee and fruits. Fruits include citrus, summer and winter varieties.2Other high erosion prone crops include pulses, spices, buckwheat, potato, oilseeds, sugarcane and barley. Pulses include lentil, chick pea, pigeon pea, black gram grass pea, horse gram, soybean and others. Spices include cardamom, ginger, garlic, turmeric and chili. Oilseed crops include mustard, sarsoon, rayo, sunflower, groundnut, sesame, linseed and niger.

• Farmlands on hill slopes are considered to be suitable for non-arable use including forestry and plantation agriculture from both environmental and economic perspective.
• Farmers are utilizing farmlands as per their suitability wherever there is an opportunity to take advantage of locational potentials such as tea, coffee and cardamom plantations (pictures)
• Easy access to market facilitated by roads has played an important role in bringing a significant change in the use farmlands, which has helped to control soil erosion significantly and at the same time increased farmers’ income considerably.
• However, such land use accounts for a negligible proportion of the total farmland.

• Unfortunately, the majority of Hill villages do not have easy accessto even the local market centers, not to mention the regional andnational centers, due to lack of roads.
• Roads have been constructed, but majority of them are either gravel or laterite, and they serve only a small percentage of the hill population (Table).

• Therefore, despite being aware of production potentials, hillfarmers have been forced to continue growing crops that requireregular hoeing and plowing of land.
• Small and fragmented landholdings, on average about 1.0 ha/householdfragmented into about 4 parcles, is another important factor constraining shift of hill farmers from arable to locationally and financially suitable non-arable land use.
• Confronted with food security, difficult access to market and scarce non-farming employment opportunities, hill farmers have continued growing mostly cereal crops, irrespective of land suitability, thoughthe total amount of crops produced cannot meet their household food requirement throughout the year due small landholdings and low crop yield.

• Scarce local non-farming employment opportunities also forces the overwhelming majority of hill farmers to keep on practicing economicallyunattractive and environmentally deleterious farming.

5. The Threat: Aggravated Land Degradation
• The hill population that contributed substantially to adoption ofhighly labor intensive land management practices, including terraces, is gradually decreasing due to permanent out-migration.

Gopal B Thapa/AIT
• Since a few years ago with the opening up of job opportunities for foreign laborers, there is a trend of ever increasing number ofparticularly Nepalese adult males from both the Hills and Tarai regions of the country going to the Middle Eastern, Southeastern and East Asian countries as wage laborers and semi-skilled workers.
• Officially, 3.3 million Nepalese laborers, accounting for more than one-tenth of the total national population, were working abroad in 2013 (AnnapurnaPost, Feb. 27, 2014). About 1,500 youths are going abroad everyday.
• Since agriculture, including management of farmlands, is highly laborintensive, the on-going rapid migration of youths has constrained agricultural activities including land management. Reportedly, in theabsence of labor, cropping intensity has been reduced and farmers arefacing difficulty to take care of farmlands appropriately.
• Thus, the on-going labor migration has threatened accelerated land degradation.
Gopal B Thapa/AIT
• The remittances sent by laborers has certainly contributed tothe national economy considerably as, reportedly, it accounts for 23% of GDP (Annapurna Post, Feb. 27, 2014).
• However, the remittance has contributed a little to enhance agricultural production and farm land management in the Hills as most of the remittance was being used for meeting basic needs, including food, and payment of loan obtained to finance the cost of out-migration (Wasti, 2012).

6. The Opportunity
• While the rapid outmigration of hill population poses a serious threat for accelerated farmland degradation, it also offers an opportunity for controlling land degradation and increasing economic return from land use.
• As individual farmers are finding it difficult to continue with the traditional arable agriculture due to labor shortage, there isan opportunity for promotion of locationally as well as economicallysuitable non-arable land use including plantation agriculture,medicinal herbs farming and private forestry.
• Besides other factors, connecting villages with market centers through all weather roads is a major challenge for promotion of plantation agriculture as well as private forestry.
• Likewise, on the policy front, the government has not yet seriouslyconsidered herbal medicine farming and private forestry as anan alternative options of traditional arable farming that that can potentially contribute to control soil erosion effectivelyas well as to increase farmers’ income.
Gopal B Thapa/AIT
• The Forest Act 1992 and Forest Regulations 1994, allow individuals to keep private forest (Niroula and Subedi, 2013). However, there are stringent regulations with regard to the sale of timber and other forest products from private forest.
• Moreover, so far there is no government policy promoting private investment in forestry, which might be partly attributed to concerned policymakers’ and bureaucrats’ apprehension that they would losedirect and indirect benefits accruing to them from their monopoly over common forest resources.
