The Origin
How a Mountain Changed Everything
In 2019, the Floral Farms neighborhood in South Dallas woke up to a crisis: a 30-foot mountain of toxic shingles had been illegally dumped directly next to their homes.
Floral Farms is a predominantly Black community — a community that had already endured decades of racist zoning practices that pushed industrial facilities, salvage yards, and waste sites into their neighborhood while wealthier, whiter areas of Dallas remained protected. Shingle Mountain was not an accident. It was the latest chapter in a long history of environmental injustice.
The mountain grew to over 200,000 tons of construction debris. Residents reported breathing difficulties, eye irritation, and constant fear for their children’s health. Government agencies moved slowly. Promises went unfulfilled.
So the community organized. Led by Dr. Marsha Jackson — a resident of Floral Farms — neighbors joined forces, filed complaints, rallied allies, engaged media, and took their fight all the way to the Texas Commission on Environmental Quality, the City of Dallas, and beyond.
After three years of relentless organizing, legal battles, and international media attention, Shingle Mountain was removed. All 200,000+ tons. It was a landmark victory — proof that frontline communities, when organized and supported, can move mountains. Literally.
Out of that fight, Southern Sector Rising was born. What began as a neighborhood emergency response became a full-fledged environmental and social justice organization, rooted in South Dallas and reaching across the globe.


Our Leadership
Dr. Marsha Jackson

Dr. Marsha Jackson is a South Dallas resident, community organizer, environmental justice advocate, and the founding force behind Southern Sector Rising.
When Shingle Mountain appeared in her neighborhood, Dr. Jackson did not wait for someone else to act. She documented the conditions, organized her neighbors, and built a campaign that ultimately forced the removal of over 200,000 tons of toxic shingles — a first-of-its-kind environmental justice victory in Texas.
Her work has taken her from Floral Farms to the United Nations climate negotiations in Kenya and Rome, where she has represented frontline communities on the global stage. She has testified before government bodies, appeared in national media, and earned recognition from organizations across the country.
Dr. Jackson’s leadership is rooted in the understanding that environmental justice is inseparable from racial justice, economic justice, and the right of every community to live with dignity and health.

How We Work
The Jemez Principles
Southern Sector Rising operates by the seven Jemez Principles of Democratic Organizing Justice — a framework developed by people of color and Indigenous communities to guide movement-building work.
Be Inclusive
Environmental justice work must include all peoples, acknowledging the leadership of those most affected by environmental and economic injustice.
Emphasis on Bottom-Up Organizing
We prioritize grassroots organizing, ensuring that decision-making power rests with frontline community members rather than external institutions.
Let People Speak for Themselves
Affected communities must have the right to speak their own truths. We create space for directly impacted voices rather than speaking on their behalf.
Work Together in Solidarity and Mutuality
We build bridges across communities and movements, recognizing that our struggles are interconnected and that collective power is our greatest strength.
Build Just Relationships Among Ourselves
Justice work begins internally. We commit to equitable relationships within our organization, rooted in respect, accountability, and shared power.
Commitment to Self-Transformation
We acknowledge our own limitations and biases, and commit to continuous learning and growth as individuals and as an organization.
Practice Nonviolence
Our movement is rooted in the tradition of nonviolent resistance — using our voices, our presence, and our organizing to create lasting change.
What Drives Us
Our Values
Three core values shape everything we do — from neighborhood meetings in Floral Farms to international climate negotiations.
Community-Led
Every campaign, program, and decision is driven by the people most directly impacted. Frontline residents are not just beneficiaries — they are leaders. We follow the community, not the other way around.
Coalition Power
No single organization wins alone. Our strength comes from our network of 150+ allied organizations spanning environmental, labor, food justice, and civil rights movements across Dallas and beyond.
Global Justice
The issues facing South Dallas are not isolated — they are part of a global pattern of environmental racism. We connect local struggles to international climate policy, bringing Dallas voices to the world stage.
