Sahelian livestock systems, an indelible feature of its landscapes and significant contributor to its economies, are under significant pressures to change. Whereas high predicted demand increases for livestock products offer great prospects for income growth, expansion of croplands and settlements as well as climate change will likely negatively impact Sahelian producers. It is clear that for Sahel to respond to livestock market opportunities, changes in traditional trade and production practices are needed, in particular to improve reach of market signals to producers, reduce the high transaction costs, and improve productivity. The Sahelian markets have to date shown continued capacity to supply growing Sahelian and regional markets, and in fact the changes, are already evident. These include expansion and diversification of trader networks, changing procurement patterns, agricultural expansion, and increased use of supplemental feeds, among others. These changes are certain to further evolve.

Czech agriculture is dealing with the consequences of climate change. Agroforestry cultures are being discursively reintroduced for better adaptability and resilience, with the first practical explorations seen in the field. Scholars have been working with farmers and regional stakeholders to establish a baseline for making agroforestry policy viable and sustainable. In a research effort that lasted three years, a large group of Czech farmers was interviewed via questionnaire surveys, standardized focus groups and in-depth personal interviews regarding their knowledge of agroforestry systems, their willingness to participate in these systems, and their concerns and expectations therewith. The information obtained helped the researchers gain better understanding of issues related to implementation of these systems. It was found that although trees are present on Czech farms and farmers appreciate their aesthetic and ecological landscape functions, knowledge about possible local synergies with crops and animals is lacking. This local knowledge gap, together with lack of market opportunities for the output of agroforestry systems and undeveloped administrative processes, have been identified as the greatest obstacles to the establishment of agroforestry systems. The researchers argue that the discovered cognitive and technological “lock-in” of the farmers may represent a risk to climate change adaptability and resilience. For the development of complex and localised land use (e.g., agroforestry) in such a context, the researchers suggest participative on-farm research, which would broaden the local knowledge base related to ecology and entrepreneurship.

Thailand is ranked among the top 10 countries most vulnerable to climate change, and its farmers have faced the risk of natural disasters almost every year for nearly 30 years. However, those affected by climate change have also been the largest contributors to climate change, increasing the risks they will face in the near future. The intensive use of chemical pesticides in conventional agriculture has harmed not only the environment and biodiversity but health of both users and consumers. Responding to these problems, several policies have been put in place over the past decades to reduce pesticide usage as well as to encourage farmers to switch to low-carbon and low-pesticide agriculture, namely, organic agriculture. This study reviews policies related to the development of organic agriculture in Thailand and examines whether organic agriculture is an effective adaptation and mitigation strategy to climate change that can also generate enough food. This study finds that the organic sector has been largely driven by the private sector, particularly the agricultural cooperatives and non-governmental organizations (NGOs), which have provided various support ranging from technology transfer, production, financing, distribution, to marketing of organic products. Their role is vital in encouraging farmers to switch to organic farming and growing market opportunities for organic goods. Nevertheless, constraints including inconsistent policies and limited support from the government remain, which, to some extent, weakens the efforts to build sustainable agriculture and climate resilience. To improve organic farming, there is a need for the government agencies to work together with all relevant stakeholders in the organic sector, namely agricultural cooperatives, NGOs, and consumers.

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).
