Brève description de la meilleure pratique

Silting up of nala/river used to be resulted in flooding and water logging of the fields situated near nala/river. This renders the land unfit for cultivation. KJBF has widened and desilted the nala/river ensuring water harvesting mechanism across the widened nala/river.

Principaux problèmes abordés par la meilleure pratique

Water logging in the field near nala/river due to flood |Soil erosion & crop failure|Less sub surface recharge|Deep water table

Décrivez les principaux problèmes liés à la dégradation des terres abordés par la meilleure pratique

In project area (Deoli taluka), the topography is mostly flat. Most of the nala/rivers have huge catchment area but due to encroachment and deposition of silt, the water holding capacity is greatly reduced. This results in flooding of the agricultural fields and washing away of seeds. The fields remain waterlogged in the absence of natural drainage and cultivable land is rendered fallow. During torrential rains, fertile top soil used to be washed away with the surface runoff and the productivity of land was also adversely affected leading to poor crop yield and low incomes for the farmers in the area.|

Précisez les objectifs de la meilleure pratique

Protection of land from water logging due to flood in Nala or River |To avoid soil erosion & maintain soil fertility|To increase sub-surface recharge rate|To increase water level in nearby wells

Brève description des principales activités, par objectif

By removing silt from nala/river the bed of nala/river gets exposed to hard murrum level through which water can be recharged very fast.
In this revived nala/river we have constructed check dams to harvest rainfall which can be utilized for support irrigation also. This will also help in increasing water level in the nearby wells.
The existing silted nala/river was widened & deepened with the help of JCB machine and the banks were raised to certain level to pass runoff safely through it.
Due to these raised banks soil erosion from the nearby fields was stopped & thus these fields can be converted into cultivable fields with maintained soil fertility.

KJBF conducted PRAs in the project villages. VVs interacted with the farmers regularly and made them aware about the importance of water harvesting. Discussions with farmers enabled to understand the problem of erratic rainfall and solution for the same was also evolved from the community itself. A Village Development Committee consisting of volunteers representing the various factions within the community was formed after members were nominated by common consensus during a village meeting. The VDC members played a crucial role in motivating the farmers and taking the process of implementation forward. The VDC was also responsible for representing the community perspective, building consensus and collecting the community contribution. |

Décrivez les impacts sur site (les deux principaux impacts par catégorie)

Green belts throughout the length of nala/river can be developed
Soil degradation was arrested resulting in conservation of top fertile layer of soil
KJBF has widened revived streams of 12.5 kms. This has helped to bring 145.5 acres of fallow land under cultivation.
Seventy five acre cropland near nala/river was protected from flood which in turn increase crop yield
Income level of farmers can be increased due to increased land availability for cultivation  

Décrivez les deux principaux impacts hors site (dans les environs)

Water conservation measures adopted along with the nala/river revival activity has resulted into recharging surrounding wells  

Impact sur la biodiversité et le changement climatique

Décrivez:

Soil erosion and runoff from cropland will respond to changes in climate for a number of reasons, including climate-induced changes in plant biomass, plant residue decomposition rates, soil microbial activity, evapo-transpiration rates, soil surface crusting and sealing, and shifts in land use that occur as adjustments to a changed climate. The most important effect of climate change on soil erosion and surface runoff, however, will come from climate-induced changes in the volume and erosive power of rainfall Practices promoted in the project area are for reduction of soil erosion and also for minimizing the effect of erratic rainfall. |
