كلا

التعليقات:

SLM practices documented in the frame of the Rustaq NRM study were established only recently (1-3 years ago). It is too early for a final judgment on the sustainability of these technologies within the human and natural environment of Chokar watershed.

2.1 وصف مختصر للتقنية

تعريف التقنية:

Local and new varieties of fruits are planted on degraded land in accordance with improved management practices. The established orchards and vineyards serve double purpose of soil protection and income generation for the rural households. The alfalfa under the trees supports tree growth and is used for livestock fodder.

2.2 وصف تفصيلي للتقنية

الوصف:

Project supported implementation of improved orchards and vineyards has taken place in the villages Sari Joy, Jawaz Khana and Dashti Mirzai, located in Chokar watershed of Rustaq District in Northern Afghanistan. The Chokar watershed is a mountainous area situated between 600 - 2,500 m above sea level. The climate is semi-arid with harsh and cold weather in winter and hot and dry summers. The annual precipitation in average years is 580mm. Land degradation affects all forms of land use and includes low vegetation cover, heavy top soil erosion from water, and poor soil fertility. Unsustainable agricultural practices, over-exploitation and high pressure on the natural resources are adversely impacting on the socio-economic well-being of local communities as well as contributing to the risk for being adversely affected by drought as well as landslides and flash foods triggered by heavy rainfall. The data used for the documentation of the technology is based on field research conducted in Chokar watershed, namely in the villages: Sari Joy, Jawaz Khana and Dashti Mirzai. These villages represent the upper, the middle and the lower zone of Chokar watershed, respectively. They differ considerably in access to services and infrastructure, but in general are poorly served. The communities depend on land resources for sustaining their livelihoods. In a good year with high yields, wheat-self-sufficiency lasts about 5 months. The three villages are home to ethnic Qarluq communities. Since 2012 the Livelihood Improvement Project Takhar (LIPT) implemented by Terre des hommes (Tdh) Switzerland has initiated a range of NRM interventions.

The rural population in Rustaq district of Afghanistan traditionally grows local varieties of apples, pears and grapes. Mostly it is subsistence farming with a small-scale local marketing. Shortage of irrigation water and lack of specific knowledge about horticultural and viticulture practices, negatively affects fruit yields. Apart of providing diverse fruits for consumption, orchards are also important for providing fodder for the livestock, retaining soil moisture and protecting the soil from erosion.

The local land users interested in the establishment of improved orchards and vineyards were mobilized through the Natural Resources Management Committees (NRMC) in Sari Joy, Jawaz Khana and Dashti Mirzai villages. In addition to the local varieties of pears, apples and grapes, new improved varieties were used for orchards and vineyards on 6.5 ha of degraded land. Such orchards were established inside or close to the villages on mountain slopes with gentle (3-5%) and moderate (6 -15%) steepness. Fruit trees are planted on locally identified dark and light soils, which correspond to moderately deep and loamy soil of medium soil fertility. Considering the medium quality of the soil, the first step of tree plantation is application of organic fertilizer. Afterwards, the plot is designed according to 4m x 4 m spacing between the trees. Under such parameters, on 1 jirib (0.2 ha) of land 125 fruit tree (apple or pear) seedlings are planted. The depth of the planting pits is 60 x 50 cm. The planted tree is watered and the lower trunk is covered with lime and water solution. Alfalfa is sown under the trees to serve as a fodder for the livestock. The orchards are irrigated mostly during summer once a week. In areas where there is shortage of irrigation water the trees are rainfed. Other maintenance activities include pest and disease control provided by a trained local specialist.

The new orchards only recently started giving fruits. The actual fruit yields are expected in 2017-2018. Expected higher yields of improved verities of pears, apples and grapes serves as a strong incentive for the local land users and their families to establish and maintain the orchards. Orchards are very demanding, but their reward is very promising in terms of improved harvest and more opportunities to sell the produce. Some land users have successful experience on their plots and already have fruits in their gardens and plan to enlarge their garden and plant more varieties of fruit trees, such as persimmons. Alfalfa which grows under the trees has important production value, particularly during the early years after the establishment phase, when the trees are too young to give fruits.

Female members of the households, which implemented orchards are also involved in establishing and maintaining orchards and vineyards. They take part in planting trees, watering, hay making and protecting the trees from livestock and people. Their contribution, plays an important part for the successful implementation of improved orchards and vineyards in Sari Joy, Jawaz Khana and Dashti Mirzai.

Dashti Mirzai has good water availability also from an irrigation channel.

5.5 التنوع البيولوجي

5.6 خصائص مستخدمي الأراضي الذين يطبقون التقنية

اذكر الخصائص الأخرى ذات الصلة لمستخدمي الأراضي:

The land users in the area where the Technology is applied belong to the Uzbek ethnic minority group Qarluq.
Although the men are generally the main land users, however, women and children also take active part in the related work. The functions of men and women are clearly distinguished within the Afghan society. At the same time within the family this division of work and functions also results in men and women working hand-in-hand. An improvement of the family’s livelihood situation is expected to positively affect all family members. While, it is recognized that the involvement of women is key in order to secure basic human rights for everyone, to achieve good governance, sustainable development, and to efficiently contribute to poverty reduction (SDC 2004), it is also clear that a context sensitive approach is of high importance.
Women in rural Afghanistan are involved in many production and income generating activities that contribute to the overall household income, however, very few women own resources such as land and livestock, and their income generating options are fewer in comparison to that of men.

6.4 تحليل التكلفة والعائد

كيف يمكن مقارنة العوائد نسبة لتكاليف الإنشاء (من وجهة نظر مستخدمي الأراضي)؟

التعليقات:

Based on the multi-criteria matrix: During the FGD with SLM implementers, a multi-criteria matrix was elaborated, and different SLM practices were rated. In the frame of this exercise, SLM implementers were asked to jointly discuss and rate short term (1-3 years) and long-term (10 years) returns of the SLM practice. As the SLM technology was only implemented 1-2 years ago, it is too early to compare benefits to maintenance costs. Farmers have little experience so far on the actual benefits of the SLM technology. The ratings are mostly based on expected benefits and not on actual benefits.

6.7 نقاط القوة / المزايا / الفرص التي توفرها التقنية

نقاط القوة/ المزايا/ الفرص من وجهة نظر مستخدمي الأراضي
The land users have high expectations about the benefits of the improved practices to grow fruit trees. They see the benefit of growing different types of fruits. Expectations are high about increased fruit yields and increased opportunities to sell more fresh and dried fruits and nuts on the local market. Fruits and nuts sell very well and can generate higher incomes for the households.
The ecological benefits of the orchards in protecting the soil from heavy rains is valued by the land users. The villagers mark improved vegetation cover as their villages are becoming greener with the fruit trees and the alfalfa in the orchards.
It is appreciated by the land users that they were introduced and provided with new varieties of fruits. They were also trained on planting and maintaining orchards and vineyards in accordance with local conditions and using such techniques as grafting, pruning, mulching, protection from pests and diseases, etc.
The orchards not only give fruits, but also are the source of fuel wood, which is made from pruning the trees. Considering that many households keep livestock, the grass under the trees and tree leaves are used to feed the livestock. In return livestock manure is used as organic fertilizer for the trees.
Some land users having seen the positive outcome of their work, are interested in enlarging their orchards. Others are ready to support those who want to plant fruit trees by sharing tree saplings or seedlings with them.
Women share the expectations of earning more money for their household through growing more fruits and selling them on the local market. In Dashti Mirzai and Jawaz Khana women are particularly excited over their grape, which still need some time to give yields.

نقاط القوة/ المزايا/ الفرص من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات
Better management practices in growing fruit trees will benefit the land user and the land through strengthening soil resistance to heavy rainfall and prevent erosion. Over the period of few more years the trees and undergrowth grass will significantly enhance infiltration and moisture retention in the soil, which in turn increase the vegetation cover and halt the degradation process.
The SLM knowledge obtained through project training is disseminating inside and beyond the villages, along with exchange of seedlings from new varieties of fruit trees. In addition to that, land users are aware of pest and disease control and have access to these services through trained specialist.
Households do not have to rely only on wheat and legumes, but are able to diversify their agricultural production even more. The expected opportunity to sell more fruits and nuts has the potential to increase households income. This in turn will enable the family to secure their food supply for longer periods.
Female family members' participation is one of the key elements for sustaining orchards and vineyards. Women highly value the importance of their work in orchards and the benefit it provides to their households.

6.8 نقاط ضعف / مساوىء / مخاطر التقنية وسبل التغلب عليها

نقاط الضعف/ المساوىء/ المخاطر من وجهة نظر مستخدم الأراضي	كيف يمكن التغلب عليها؟
Lack of irrigation water is a crucial issue, especially in Jawaz Khana, which makes it very difficult for the land users to maintain their orchards.	Rehabilitate the Yakhdons. Yakhdon is a local storage method for collecting snow water in winter to be used for drinking and irrigation in spring and summer. One Yakhdon can provide water for up to six months. Several of these Yakhdons are destroyed and their rehabilitation would provide better access to water for Jawaz Khana.
The young trees are sensitive to droughts and need to be watered regularly to ensure that they survive.
Establishment of orchards requires hard work and sufficient money from the land user to buy seedlings and in some cases to build a wall around the orchard or build an irrigation canal.

نقاط الضعف/ المساوىء/ المخاطر من وجهة نظر جامع المعلومات أو غيره من الاشخاص الرئيسيين لمصدر المعلومات	كيف يمكن التغلب عليها؟
The establishment of orchards is reported as one of the most labour-intensive SLM practice for both men and women. Working in orchards increases the burden of women in addition to their household chores.
Technical knowledge on planting and maintaining fruit trees and grapes is required to ensure tree survival, good productivity and protection from pests and diseases.
