Kenya’s Mazingira Week 2026 is taking an institutional approach to environmental conservation, with different sectors assigned specific days to lead tree-growing and clean-up activities ahead of National Mazingira Day.
The week began on Monday, October 5 and will culminate on Saturday, October 10, when Kenya marks National Mazingira Day under the theme, “Our Environment, Our Responsibility: Collective Action for Tree Growing and Environmental Stewardship.”
The programme is designed to mobilise institutions and citizens across the country around practical environmental action.
Tuesday, October 6, is designated Mazingira Education Institution Day. Tree planting and environmental clean-ups are expected in education institutions across the country, including basic education institutions, TVETs and higher education institutions.
Wednesday, October 7, will focus on mine-site restoration, with activities planned in Kakamega, Siaya, Migori, Busia and Kisii. The State Departments for Mining and Forestry will lead the activities.
Thursday, October 8, has been designated Mazingira Highway Greening and Drainage Cleanup Day. The State Departments for Roads, Transport and Forestry will lead the programme.
On Friday, October 9, all 47 counties will participate in Mazingira Cleanup Day, with clean-up activities planned within county headquarters under the leadership of the State Department of Climate Change and the National Environment Management Authority.
The activities will culminate on Saturday with National Mazingira Day, also designated National Tree Growing Day.
The week’s activities form part of a larger target to plant 17.24 million trees through seven planting streams.
The Government says 7.7 million trees will be planted through village elders across 77,252 villages. Kenya Forest Service and Community Forest Associations will lead a five-million-tree target at 79 sites in 31 counties.
The National Youth Service will plant 1.5 million trees, while the Kenya Prisons Service will plant one million trees in 68 correctional facilities.
TVET institutions will target one million trees, basic education institutions 640,000 and higher education institutions 400,000.
The programme is part of Kenya’s wider ambition to grow 15 billion trees by 2032.
Government Spokesperson Charles Owino said environmental conservation should become a practical responsibility for citizens, institutions and communities.
The national theme, he said, is more than a slogan and is a call for every Kenyan, every level of government, communities, development partners, the private sector and civil society to take personal and collective responsibility for growing and protecting trees.
The Government is also introducing tracking measures to ensure the campaign produces lasting results.
Every tree will be counted, geo-tagged and certified, with the JazaMiti platform supporting real-time monitoring. The programme will include 90-day survival checks and quarterly tracking of pledges.
National Mazingira Day will be hosted in Trans Nzoia County, where the Presidential Green Challenge will target 5.1 million trees at 79 sites across 31 counties.
The Government says the programme will continue annually, making environmental restoration a sustained national effort rather than a once-a-year activity.
