Rainwater harvesting systems are crucial for climate change adaption in climates with a pronounced dry season and especially under rainfed agricultural systems. Earthen storage ponds can be easily constructed in rural areas and expanded in their functionality to
not only store water, but also to produce aquatic plants and animals.
Particularly important plants in this context are Azolla spp. and duckweeds that are both among the most productive plants providing potential sources of animal fodder, bio-fertilizer and energy, while acting as biological control against malaria spreading mosquitoes by covering the pond surface and even reducing the evaporation rate of the pond. A variety of different aquatic plants can be grown inside productive ponds to provide a great variety of agricultural products, boost biodiversity of agricultural systems and contribute to more stable and more resilient ecosystems. The high biomass productivity of certain aquatic macrophytes enables an accelerated soil building rate by supplying bio-fertilizer and mulch to agricultural fields in amounts that are hardly achievable in soil-based environments.
