Hand Drawn Permaculture Design 
Land Size: 2.5 Acre
Type: Ridge & Slope
Challenges/ Needs
1. Diverse soil profiles ranging from clay to sandy loam & gravels. 
2. Low waterholding capacity of soil. 
3. Diverse slopes throughout the property, ranging roughly from 2 to 75 percent. 
4. Existence of invasive non-native invasive species. 
5. Fire-prone zone. 
6. Top Soil loss due to soil erosion during heavy rains, winds & annual farming activities. 
7. Situated on ridge thus subject to quick moisture loss post heavy monsoons. 
8. Uncontrolled movement of cattle leading to overgrazing.

Solutions

1. Studied soil profiles to select earthworks & plant species specific to soil type & water retention capacity, added in pioneer species & edible ground cover plants to retain moisture & drain excess moisture accordingly. 
2. Added biomass to the soil along with plantation of ground cover & earthworks on the slopes like swales & boomerang trenches to increase the water holding capacity by reducing the evaporation. Also, seeping water underground to increase underground moisture by utilising the natural slopes & gravity. 
3. Selection of plant species based on slope orientation & geology to plant on the slopes. Utilising gradual & flat spaces for pathways & annual vegetable beds. 
4. Chop and drop invasive species before the flowering stage to ensure suppression of new growth. Utilising water-filled swales in monsoon to decompose the roots stalks of invasive species like lantana to prevent resprouting. 
5. Increasing moisture in soil with earthworks & plantation of evergreen species around the fire sector to reduce the impact of fire and prevent fire entry. Also, the plantation of agave along the fence acts as a fire-resistant barrier. 
6. Designing of swales around annual farming fields to catch & collect the eroded soil. Selection of more perennial vegetables to reduce dependence on annual tilling. Plantation of soil stabilizing species like vetiver, citronella & lemongrass along the slopes & earthworks to prevent erosion. Maintaining grass cover of native species to prevent direct exposure of soil to wind, rain & movement. 
7. Utilising the natural landscape to harvest the rainwater & drain the excess effectively without destabilising the landscape by carefully selecting areas for swales & trenches. 
8. Plantation of live fence made up of native shrubs & thorny bushes species along with plants which are not preferred by cattle to grow together as a dense self-sufficient barrier. An opening for allowing supervised grazing has been ensured during implementation.
