Tropical Home Gardens: Biodiversity, Climate Resilience, Nutrition
TL;DR: Tropical home gardens offer a sustainable, climate-resilient solution for food security and biodiversity, reducing reliance on external markets.
- Home gardens boost food security and biodiversity.
- They enhance climate resilience and adaptation.
- Gardens reduce dependency on food markets.
- Integrated designs maximize diverse growing spaces.
- Traditional knowledge is key for sustainable practices.
Why it matters: Tropical home gardens provide a practical pathway to address food insecurity and climate challenges, particularly for vulnerable communities. They offer a tangible method for communities to adapt to changing environments and improve their nutritional well-being.
Do this next: Explore local government or NGO programs that support establishing or enhancing home gardens in your region, focusing on diverse cropping strategies.
Recommended for: Individuals, communities, and policymakers in tropical regions interested in sustainable food production and climate resilience.
This CGIAR compilation of abstracts on tropical home gardens underscores their role as biodiverse, climate-resilient, and nutrition-sensitive agriculture systems. Home gardens conserve natural resources, aid climate mitigation and adaptation via carbon sequestration, enhanced forest cover, and household adaptation pathways. Drawing from global case studies, it highlights low resource use, adaptability to diverse conditions, and resilience to crises. Examples include interventions in seven production niches (open sunny places, rooftops, trellises, fences, boundaries, marshy lands, partially shady areas) following the Rangpur model in Bangladesh, yielding up to 511 kg/year of vegetables for small farmer groups. Other cases cover Kerala, India (2006), tribal home-gardens for climate adaptation in protected areas (2024), and connectivity of local wisdom in Rural Kupang City (2024). These gardens reduce food market dependency, enhance resilience to economic and environmental shocks, and improve nutrition. Factors like socioeconomic status, climate, and education influence sustainability. The review notes gaps in long-term research and methodological limits, such as underrepresented populations and external factors. Practical details emphasize year-round production, tree community structures, and socio-ecological solutions integrating Indigenous knowledge. Home gardens mitigate food insecurity from disasters, with interventions boosting output in challenging terrains. Key methods involve diversifying crops across niches, conserving biodiversity, and leveraging traditional practices for self-sufficiency. Impacts include better health outcomes, reduced vulnerability, and community empowerment, positioning home gardens as scalable for regenerative living in tropical climates with concrete, documented results from field interventions.
