Trees for Money and Food: How PlantVillage's Agroforestry Initiative is Transforming the World
Posted on
On this year's International Forests Day, it's crucial to acknowledge PlantVillage's dedicated efforts in advancing food security, employment opportunities, and contributing significantly to combating the climate crisis.
PlantVillage has positioned itself as a leading force in transformative initiatives aimed at bolstering global efforts to safeguard and expand forest coverage, an endeavor that not only safeguards food sustainability but also provides sources of income for disadvantaged families.
Utilizing cutting-edge AI tools like the PlantVillage app, the organization has spearheaded vital projects which include the production of biochar, cultivation of high-value fruit tree seedlings, and comprehensive farmer training programs.
These efforts are pivotal in ensuring the sustainability of tree cultivation, particularly on farmlands.
Biochar for the soil
At the core of the biochar project lies the utilization of biochar, a remarkable soil amendment derived from the pyrolysis of plant biomass.
Unlike traditional fertilizers, biochar offers a sustainable approach to soil enrichment, enhancing its fertility while combating climate change.
Afforestation endeavors face daunting challenges in regions plagued by arid conditions, such as Northern Kenya. However, PlantVillage's incorporation of biochar has sparked newfound hope.
The efficacy of biochar is evident through the expertise of individuals like Saniwa Rose, an agroforestry lead in Northern Kenya.
"Trees nurtured with biochar exhibit remarkable resilience and higher survival rates, defying the odds of harsh environmental conditions. The benefits of biochar transcend mere soil enhancement. Its remarkable ability to retain moisture proves invaluable in mitigating water stress for trees, particularly in arid climates," she said.
Furthermore, biochar is a powerful ally in the fight against global warming, acting as a carbon sink by sequestering carbon from the atmosphere. PlantVillage's commitment to producing over 800 metric tons of biochar by the end of 2024 underscores its unwavering dedication to sustainable practices and environmental stewardship.
"So far, we have managed to produce 228 metric tons of biochar. Currently, our main sources of biomass are Prosopis juliflora, coconut husks, and maize stalks," said John Mayieka, PlantVillage’s biochar lead.
Before incorporating the biochar into the soil, it is charged. The mixed manure can consist of chicken droppings or cow dung in a specific ratio. This fertilizes the soil, making it more productive, as evidenced by the well-growing trees.
"For instance, last year in Turkana County, we conducted a comparison study. We exposed 10 Grevillea robusta tree seedlings to the same environmental conditions. Out of these, five were planted with biochar, while the remaining five were not.
“After one year, there is a significant difference: the ones planted with biochar grew faster and are much stronger compared to those planted without biochar," added Saniwa.
High-Value Fruit Tree for Money and Food
The PlantVillage agroforestry team in Kenya is crafting biodegradable potting tubes from cardboard as an eco-friendly solution for cultivating high-value fruit trees.
This initiative is aimed at concerning the environment, expanding forested areas and creating job opportunities.
The tree seedlings are enriched with biochar and mycorrhizal fungi for them to be tolerant to pests, diseases and harsh climatic conditions.
The project is engaging farmers in Bungoma, Busia, and Baringo counties through employment in nurseries while selling the seedlings on loan, fostering active participation and repayment upon harvest.
Farmer training
In addition to these innovations, the organization has been encouraging farmers to embrace agroforestry by training them before being supplied with tree seedlings on how to plant and care for them, considering that most of them are not well-versed in crop farming.
These innovative solutions exemplify the power of ingenuity in safeguarding our planet's forests. PlantVillage is not only addressing environmental challenges but also fostering sustainable agriculture and economic empowerment in local communities.
