Oasification
Soil Preparation:
Terracing: To reduce runoff and increase water infiltration.
Mulching: To conserve moisture and improve soil fertility.
Adding Organic Matter: To enhance soil structure and water-holding capacity.
Plant Selection:
Native Species: Choosing local species adapted to the area's conditions.
Drought-Resistant Varieties: Selecting species that can survive with minimal water.
Pioneer Species: Starting with species that can improve soil conditions for other plants.
Water Harvesting:
Swales and Contour Bunds: Earthworks that capture runoff and increase water infiltration.
Rainwater Harvesting: Collecting and storing rainwater for dry periods.
Check Dams: Small barriers built across small waterways or gullies to capture water.
Irrigation Systems:
Drip Irrigation: Delivering water directly to the plant roots to minimize waste.
Micro-Irrigation: Using low-flow systems to provide water to the plants efficiently.
Erosion Control:
Windbreaks: Planting trees or shrubs to reduce wind speed and protect soil and young plants.
Ground Cover Plants: Establishing plants that cover the soil surface to protect against erosion.
Slope Stabilization:
Geotextiles: Using biodegradable mats to protect against erosion while plants establish.
Retaining Structures: Building walls or other structures to stabilize steep slopes.
Monitoring and Maintenance:
Regular Assessments: Checking the health of the vegetation and the effectiveness of erosion control measures.
Adaptive Management: Adjusting strategies based on monitoring results and changing conditions.
Oasification projects require a multidisciplinary approach, involving not only engineers and environmental scientists but also local communities, ecologists, and policymakers. The goal is to create a self-sustaining ecosystem that can resist desertification processes and provide ecological, economic, and social benefits.
The term "oasification" was coined in 1999 by Andrés Martínez de Azagra Paredes, PhD Forest Engineer and professor on Hydraulics and Forest Hydrology at E.T.S. of Agroforestry Engineering in Palencia, University of Valladolid, Spain.

Oasification
Description
Oasification is the antonym to desertification by soil erosion. To help the oasification process, engineers aim to develop a thriving dense woody plant cover to redress the hydrological, edaphic and botanical degradation affecting a slope.
