Under the People Partner with Nature Program, which aims to "reduce the destruction of forested Kenya’s Key Biodiversity Areas (KBAs) and contribute to the realization of best participatory forest management practices for the benefit of all", Nature Kenya is supporting communities in the Taita Hills to increase their resilience to climate change. The formation of agricultural self-help groups and the introduction of climate-smart agriculture are only some of the various interventions implemented under the program. In this project description, we present the use of greenhouses as a solution to climate change and increased food productivity.
Taita Hills consists of the Dawida and Mbololo massifs and are part of the Eastern Arc Mountains in the south-eastern corner of Kenya. Climate change is another driver of vegetation cover change in this mountainous area, causing prolonged droughts that make life increasingly difficult for the population and small farmers who rely heavily on rain-fed agriculture. These changes have also led to a high incidence of crop pests and diseases, damaging agricultural productivity and increasing the vulnerability of the communities living here.
In 2015, Nature Kenya supported the Mwavunyu Chakiloli self-help group, which consists of some 15 farmers involved in vegetable cultivation, to construct greenhouses and drip irrigation. Greenhouses were chosen because they can extend growing seasons and create optimal growing conditions by regulating humidity and temperature. These same attributes also make it possible to continue farming amidst periods of rain scarcity, making cultivation less prone to drought events. Another advantage is that the spread of crop pests and diseases can be better controlled compared to open fields.
Following the assembly of the garden and planting inside the greenhouse, an irrigation system was constructed with plastic pipes that have "drippers" that slowly emit drops of water. This drip system has a reliable source of water supplying the pipes, and the growers monitor the plants to make sure they receive the right amount of water. The system is easy to manage and maintain once installed, requiring only monitoring of the water supply.
