Climate variability and change in the spices and plantation cropping systems in Kerala state, India

Kerala state in India has rich bio-diversity and tropical rain forests and is spread in 13 agro-ecological zones under the humid tropics. Rainfall decline (annual as well as monsoon), increase in temperature and climate shift towards lesser humid zones within the humid climate are the notable characteristics of the state. Cropping system changes, as well as changes in the production of spices and plantation crops in Kerala, were analyzed from 1952-53 to 2018-19. Area and production changes of various crops in the Idukki district have also been studied and presented in this paper. The average temperature in Kerala has risen by 0.65 °C from 1956 to 2014. In Idukki high ranges, the maximum temperature is increasing, and the minimum temperature is declining, resulting in a widening of temperature ranges. Such a scenario may adversely affect the thermo-sensitive crops, which may need urgent attention as these crops are grown in the forest-agro-ecosystems across the Cardamom Hill Reserve (CHR) of the Idukki district. Deforestation, the shift in cropping systems, declining wetlands, and depletion of surface and groundwater resources had deepened the adverse effects of floods and droughts on spice and plantation crops. Therefore, there is an urgent need for proactive steps on a short and long-term basis against the climate change risks for the sustenance of crop production both in terms of quality and volume

Risk factors for the transmission of kala-azar in Fangak, South Sudan

This article reports a case controlled study of kala-azar done in Fangak County in 2007. Fifty-six percent of the cases were under 5 years old. Most patients came for treatment two months or more after the onset of symptoms.Outdoor night-time activities and the use of “smoking” (non-insecticide treated) bed nets were associated with kala-azar infection whereas the use of bed nets during the rainy season decreased the risk of infection.It is recommended that there should be a greater distribution of treated bed nets and more kala-azar treatment centres in the county.Note: This article reports the results of a study into some risk factors for the transmission of kala-azar in Fangak in 2007. There was another recent outbreak in this area on 2010 (1, 2). Recommendations were again made to distribute more treated bed nets and to open more kala-azar treatment centres. The official Ministry of Health guideline for the treatment of kala-azar is at the end of this article

On Farm Validation of Organic Farming Technology in Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson)

Currently alternative agricultural systems, like organic farming, that are less chemical intensive, less exploitative and that can conserve the environment are gaining popularity. Tuber crops, especially aroids, like elephant foot yam, respond well to organic manures and offer scope for organic production. However, lack of package of practices recommendations hinders the promotion of this viable alternative farming practice. Hence, the organic farming technology for elephant foot yam developed at CTCRI was validated through on farm trials under State Horticulture Mission funded programme. Demonstration trials were conducted during 2008-2009 in 10 farmers’ sites to cover an area of 5 ha in Kollam and Pathanamthitta districts of Kerala to compare the yield, quality, economics and soil fertility under the organic management practices with the existing farmers’ practice and conventional practice (present package of practices recommendations) in elephant foot yam. Organic farming resulted in higher corm yield (34.60 t ha-1) and additional income (Rs. 43,651 ha-1) over conventional farming. Organically produced corms had significantly higher dry matter and Mg contents and significantly lower oxalate content. The chemical properties of the soil, especially K, were also seen favoured under organic farming. The organic farming technology standardized for elephant foot yam includes the application of farmyard manure (FYM) @ 36 t ha-1, green manuring with cowpea to generate 20-25 t ha-1 of green matter in 45-60 days, neem cake @ 1 t ha-1 and ash @ 3 t ha-1.FYM and neem cake are to be applied in pits at the time of planting. Ash may be applied at the time of incorporation of green manure at 45-60 days after planting
