Climate change could have significant impacts in the Philippines on large sections of the population who are poor and vulnerable, especially those who live in areas prone to coastal storms, drought and sea level rise. The sectors mostly affected by climate change are agriculture and food security because of the risk of low productivity due to increasing temperature, drought, and increasing frequency and intensity of rainfall that brings about floods and landslides.Located in the northernmost tip of the country, the Batanes group of islands lies on the country’s typhoon belt. Because of vulnerability and isolation from the rest of the archipelago, the Ivatans have developed self-sufficient, organic and climate-resilient crop production systems. This paper presents the indigenous crop production systems that have made the Ivatans food self-sufficient despite vulnerability of their agroecosystem.A typical Ivatan farmer owns 3-7 parcels of land. Each parcel has an average size of 300-500 m2. Farmers practice a rootcrop-based multiple cropping system with specific spatial arrangements of corn (Zea mays), gabi (Colocasia esculenta), yam (Dioscorea alata) and tugui (Dioscorea esculenta), using corn stover, hardwood trees or a local reed called viyawu (Miscanthus sp.) as trellis. Banana (Musa sp.) and assorted vegetables are planted around the parcels. One to two parcels are planted per season and the rest are left to fallow and used as grazing areas for cattle. The same crops are planted on the other parcels in the next season and the first two parcels utilized will again be planted only after 3-5 years. This unique fallow system maintains soil fertility without the use of chemical fertilizers. They also practice an indigenous storage system that involves hanging of their harvest such as corn, rice, garlic and onion bulbs, even meat and fish, above the firewood-fed cooking area. For generations, the Ivatan farmers’ indigenous agricultural production systems have ensured a food security at the household level.

Biotechnology has been widely acknowledged as a modern tool that holds the potential to improve agricultural production. Adoption of genetically modified (GM) crops could contribute toward alleviating food insecurity in Kenya, but the attitudes and perceptions of stakeholders are crucial to the acceptance of GM products. The aim of this study was to assess public perceptions of GM crops and foods in Trans-Nzoia County, Kenya. A semi-structured questionnaire survey was conducted with 179 respondents, including 55 farmers and 124 consumers, in both rural and urban areas. The results were analyzed to determine predictors for the willingness to produce and consume GM crops and food products. Farmers' and consumers' perceptions influenced their approval of the use of GM technology. The results indicate that gender, basic knowledge of GM technology, and information access and dissemination are likely to influence the adoption of GM technology by farmers. Consumers who are familiar with government policy and have basic knowledge and share information on GM crops are more likely to approve of the technology than those who do not. Farmers were concerned with the environmental risks associated with GM technology and its possible effect on marketing crops both locally and abroad. Consumers expressed concerns about possible health risks, the ability of the government to protect them, and the acceptance of GM products in the local market. Disapproval of GM products by both farmers and consumers was influenced by the perception of high risks and low benefits. The findings of this study can help policymakers when designing public awareness and risk-communication strategies targeting farmers and consumers to address potential concerns when promoting the use of GM technology.
