Ocean currents mainly result from the interaction of wind forces, that are basically driven by temperature differences arising from the heating of solar radiation, and the Coriolis effect due to Earth’s rotation. This means a combination of factors induce the large-scale movements of water around the world. Besides these, variations in the density of water, based on their temperature and salinity, contribute to inducing the vertical circulation, often referred to as thermohaline circulation, which then contributes to governing the global climate and marine ecosystems.
- Effects on climate: Warm Ocean currents, as the Gulf Stream, transfer warmth from equatorial regions toward higher latitudes, warming local conditions there by moderating coastal climates. Conversely, cold ocean currents cool adjacent areas and may even be responsible for more moderate or cooler coastal climates. S
- Fishing Impact: Ocean currents help in the nutrient upwelling within some regions where cold, nutrient-ice water rises towards the surface. In such up-welling zones, there is such rich fishery as plankton blooms thrive, attracting large fish population and in creating marine biodiversity, making them critical for global fisheries.
- Navigation Implications: Ocean currents also affect maritime navigation. The navigators must make considerations regarding the currents when charting routes since such influence a lot of changes in relation to speed because their forces can act in a manner that increases or hinders travel.

Model Answer
Introduction
Micro-watershed development refers to the integrated management of small-scale watersheds to enhance sustainable land and water resources. This approach employs conservation measures, land-use planning, and community involvement to improve water availability and soil health, particularly in drought-prone and semi-arid regions of India.
Role of Micro-Watershed Development in Water Conservation
Soil and Water Conservation
Micro-watershed projects emphasize soil and water conservation techniques such as contour bunding, check dams, and water harvesting systems. These practices significantly reduce soil erosion and enhance water retention in the soil, leading to improved moisture availability. For example, the implementation of check dams in regions like Rajasthan has been shown to increase groundwater levels by up to 30%.
Rainwater Harvesting
These initiatives promote rainwater harvesting, crucial for recharging groundwater aquifers. By capturing and storing rainwater, communities can ensure a sustained water supply during dry spells. Studies indicate that effective rainwater harvesting can increase water availability by 20-30% in arid areas.
Sustainable Agriculture
Micro-watershed projects advocate for sustainable agricultural practices, including crop diversification and efficient irrigation methods. These practices not only conserve water but also enhance soil fertility and reduce dependency on chemical fertilizers. For instance, the adoption of drip irrigation has been shown to reduce water usage by up to 40% in various agricultural settings.
Community Participation
Involving local communities in planning and implementation fosters ownership and long-term sustainability. By engaging residents, these projects ensure that water conservation measures are culturally appropriate and effectively maintained.
Livelihood Improvement
Micro-watershed development also creates alternative livelihood opportunities through less water-intensive activities like horticulture and livestock rearing. This diversification helps build resilience against drought conditions.
Conclusion
Micro-watershed development projects have proven effective in conserving water resources in drought-prone and semi-arid regions of India. By enhancing soil health, promoting groundwater recharge, and providing alternative livelihoods, these projects contribute significantly to sustainable development. Their success hinges on proper planning, community involvement, and the adoption of sustainable practices.
