第1节 最佳实践的背景:框架条件(自然和人类环境)

最佳实践的简短描述

High human and livestock population in the desert are leading to mismanagement of the sandy terrain causing reactivation and land degradation resulting of sand movement. This moving sand encroach productive agricultural fields, human habitation, canal, road and railway tracks. The most effective method was the control through a careful plantation of trees, shrubs and grasses. Calligonum polygonoides was the most suitable species, which provided better microenvironment and helpful in developing effective surface vegetation to control sand drift. Combination of C. polygonoides with Cassia angustifolia was best to control sand drift. These adult neighbours are also helpful to improve biodiversity and ecology of the arid areas. |

地点

Shifting dune,semistabilised dune and the inter-dune plane in Gadwala Forest Block, near Kotri in Bikaner Division, Rajsthan|

指定地点内的自然环境简介。

Undulating shifting dunes
Arid, rainfall ranging from 150 to 400 mm, and high wind velocity|
Aridisol with low water holding capacity, low nutrients|

居住在该地点及/或附近居民的普遍社会经济状况

Agriculture, animal husbandry|
Highly variable depending on source of income, varies between Rs. 4045.00 and Rs. 12294.00. People with both agriculture and animal husbandry practices have higher income.|

根据哪些标准和/或指标(与战略无关),在确定建议的实践和相应的技术是否被认为是“最佳”时,应该基于哪些标准和/或指标(与战略无关)?

Introduction of under shrubs and grasses along with the tree species could provide beneficial effects in controlling sand reactivation and drift, particularly, at the time when planted seedlings attain the size of a tree facilitating free air movement under the canopy resulting in reactivation of sand drift. Further, dunes are also deficient in soil organic matter and nutrients, particularly nitrogen. Therefore nutrient management practices can be adopted and sowing of leguminous and / or non-leguminous under shrubs or grasses to increase nitrogen and organic matter may be the important options. They not only increase the soil nutrient status but also provide fodder for livestock in addition to sand drift control |

第2节 解决的问题(直接和间接原因)和最佳实践的目标

最佳实践解决的主要问题

Sand movement|Reactivation and degradation of land|Fodder and fuelwood scarcity|Low soil productivity

概述最佳实践解决的具体土地退化问题

Control of wind erosion and water erosion, improvement in land productivity and conservation of soil and water resources|

具体说明最佳实践的目标

Find out suitable combination of tree species and surface vegetation for sand dune stabilization

第3节 活动

按目标对主要活动进行简要的描述

Fuel wood production|Biomass from surface vegetation|Leaf of C. angustifolia for medicinal uses
Sand drift control|Soil seed bank and regeneration|Increased fodder supply
Increase in carbon stock |Improved soil nutrients

本技术的简要说明和技术规范

The experiment was laid out in a split plot design with three replications. Three plant species viz. Acacia tortilis, Prosopis juliflora and Calligonum polygonoides of about 20 cm, 40 cm and 15 cm in height respectively, were planted in September 1996 at a spacing of 5 m x 5 m and in a pit size of 45 x 45 x 45 cm3. Species were considered as the main plot with 75 trees per species. 9.0 g of DAP (di-ammonium hydrogen phosphate) was spread in each pit as basal dose|

分析

第5节 对影响的贡献

描述现场影响(按类别划分的两类主要影响)

Increase in carbon stock
Increase in Fuel wood production
Increased income by harvesting grasses and leaves of C. angustifolia for medicinal uses.
Increase in diversity and land productivity
Increase in surface biomass production

对生物多样性和气候变化的影响

解释原因:

Adult neighbours are helpful in developing effective surface vegetation to control sand drift. They are also helpful to improve biodiversity and ecology of the arid areas by enhanced soil fertility
Adult neighbours can sequester the carbon in the form of biomass and also add the soil organic matter to the adjacent soil. These positive benefits will play a important role in climate change mitigation
Increased fodder and fuelwood and income sources
