AbstractClimate change poses serious threats to agriculture. As a primary staple crop and major contributor to agriculturally derived greenhouse gas (GHG) emissions, rice systems are of particular significance to building climate resilience. We report on a participatory assessment of climate resilience in organic and conventional rice systems located in four neighboring villages in Negros Occidental, Philippines. The Philippines is one of the foremost countries impacted by climate change, with an increasing incidence of climate-related disturbances and extensive coastlines, high population density and heavy dependence on agriculture. Using the United Nations Food and Agriculture Organization's Self-evaluation and Holistic Assessment of climate Resilience of farmers and Pastoralists (SHARP) tool, we measured 13 agroecosystem indicators of climate resilience, and assessed the degree to which household, farm, and community mechanisms and outcomes impact adaptation capacity, mitigation potential and vulnerability. We used a participatory approach to situate these indicators in their socio-ecological context, and identify targeted interventions for enhancing climate resilience based on local farmer experiences and socio-ecological conditions. Comparison of climate resilience indicators across organic and conventional rice systems in this region indicated that organic rice systems are more climate resilient than their conventional counterparts. As such, increased policy support for the development of organic rice systems are critically important as an adaptive mechanism to augment food security, mitigate GHG emissions and improve climate resilience in the Philippines.

This study aimed to explore the impacts of climate change on agricultural production in the sandy coastal communes of Quang Tri and local people’s indigenous knowledge in adapting to climate change, specifically drought. The tools for participatory assessment such as household interviews, focus group discussions and field observations were used to gather information for the research. The research results showed that climate change, especially drought, had significant impacts on agricultural production in the study area. Reduction of cultivating land, spread of crop pests and animal diseases rise of production costs, fall of productivity and degradation of agricultural product quality were the major impacts. Local people have applied various indigenous knowledge and experience to adapt to drought such as using drought resistant crop varieties; soil moisture conservation techniques; knowledge of management and prevention of animal diseases. The study showed that in order to improve local people’s ability to adapt to drought, their indigenous knowledge and experience should be documented and disseminated by integrating with production guidance activities, agriculture extension plans and operation of non-governmental organizations. Keywords: drought, agriculture in sandy area, climate change, indigenous knowledge, adaptation.

This paper has applied participatory tools to assess the livelihood resources and adaptations in Madi Valley, Nepal. It has utilized the social, economic, and environmental aspects of the identified adaptations through participatory scoring (1 to 5) for participatory cost-benefit (PCB) analysis. Additionally, it considered gender equality, technical feasibility, inclusiveness, future vulnerability for multi-criteria assessment (MCA). Series of focus group discussions (FGDs) were conducted to generate data based on communities’ perceptions. Based on PCB ratio, afforestation was the most prominent adaptation strategy, whereas early warning siren and evacuation tower (EWSET) was found the most effective adaptation based on the MCA.

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
