How to Reforest a Steep Slope Without Swales or Irrigation
12:35 minute video shows how native grasses can be planted in lines or curves to help slow down water enough to help it penetrate a hillside slope without disrupting the soil integrity.
The lady explains her choices of native tree species interplanted within the native grass, how the evergreens provide shade and protection to the rainforest species. She explains how the grasses help protect her saplings from freezing and baking hot weather. However she comes along periodically to weed away vines and grasses to prevent them from strangling the saplings, then uses the weeded materials as free mulch to further lock in moisture.
This example is in Australia so she also explains how the different species will support local natives including koalas.

The SVP-NGO Partnership "SVP India, through its chapters, gives financial grants and mentoring support to NGOs working primarily in the areas of livelihood, employment, and income generation.
SVP typically provides a grant of Rs 10 – 15 lac per annum to the NGO. However, the greater benefit for our investee organizations lies in leveraging the time, skills, and expertise of the SVP partner group, the value of which can easily be 3 – 5x of the financial support.
Our partners act as mentors, supporting the founder and top management of the NGO to achieve their goals. We provide strategic guidance, as well as open our networks to the NGO, removing roadblocks in order to accelerate the growth of our investee NGOs.
SVP’s unique model allows for both financial, and non-financial support of qualifying NGOs."WASH "curriculum has been developed and integrated in schools (Shikshaniketan, Residential Bridge Schools & Solar Bridge Schools) run by Barefoot College International.

Isla Urbana "has designed an environmentally, socially, and economically sustainable rainwater harvesting system that collects and cleans rainwater for households, schools, and health clinics.
The system is inexpensive, easy to install, and provides individual residences with about 40% of their annual water supply. If implemented on a large scale throughout Mexico City, this simple technology could provide 30% of the city’s water and help give a sustainable water source to the 12 million Mexicans who lack access to clean water."
