This study, carried out in two villages in the CHT, examined cultivation techniques, productivity, contribution to household income and its role in supporting resilience to climate change. The study adopted a participatory rural appraisal approach; data was collected through focus group discussions, structured interviews and field observation. Sixty five per cent of farmers in the two villages cultivate spiny coriander; the mean plot size was 0.12 ha. The cropping cycle starts in January and continues until October. Production averaged 59, 219 kg per hectare with a net benefit of about US$51,212/ha/yr. Eighty six percent of farmers who cultivate the crop do so solely for the purposes of income generation. Good market demand for the crop means that farmers obtain substantial economic benefit from its cultivation. It also has the potential to build the climate change resilience of marginal farmers. The findings suggest that policies to support the development of this crop have the potential to enhance marginal farmers’ financial capability and climate resilience.

Historically this involves which yield better economic return either in jhum or shifting slash and burn cultivation with a 4-5 yrs permanent agriculture7.However, it has been reported fallow period. In the last three decades, the population that the cultivation of crops such as Ada, Halud and in CHT has more than doubled, substantially others on the hill slopes causes severe soil erosion, increasing pressure on land resources. As a further degrading the land and causing yield decline4. consequence the jhum fallow period has been reduced to Furthermore, their production is believed to be 1-2 yrs2,3 and also there is permanent culture of some affected by changes in the rainfall regime, micro- areas. Repeated cultivation of land due to the shortening climate, and hampered ecosystem functioning due to of the fallow period has resulted in land degradation, soil deforestation which has occurred over the past fertility loss and severe soil erosion4.

For this reason, high yielding hybrids and jhum within this shorter cycle has also contributed to varieties of major crops, e.g. Tomato (Lycopersicon indiscriminate destruction of forests resulting in wider esculentum Mill.), Begun (Solanum melongena L.), ecological degradation and loss in eco-system service5,6.
