Livestock are not only suffering from climate change, but also contribute to climate change through the direct and indirect release of greenhouse gases (CH4, N2O and CO2). Characterization, identification and conservation of heat tolerant livestock breeds are basics for future challenging climate. Properties of the skin, hair, coat color, coat type, sweating, respiration capacity, tissue insulation, surface area relative to body weight, endocrinological profiles and metabolic heat production are important factors involved for heat tolerance. Selection based on these phenotypic characteristics is play indispensible for climate change adaptation and mitigation.  Molecular information is used to know the candidate gene for heat tolerance, their action, specific function and location on chromosomes thereby important for modification of gene and selection of heat tolerant breed and feed efficient animals. Genomic information also used to identify genes that regulated during a stressful event can lead to the identification of animals that are genetically superior for coping with stress. Marker assisted selection and proteomics may also be valuable in selection for secondary traits linked to adaptation, such as the genes for high levels of blood urea and ruminal ammonia in certain genotypes, associated with adaptation to low-quality C4 grasses. Scientific research results demonstrated that heat tolerance is heritable trait and variable between/within livestock breeds, thereby variation and heritability of the trait opens the window for selection of heat tolerant animals. Therefore, the combined genomic selection using genome wide DNA markers that predict tolerance to heat stress and phenotypic selection could be accelerated breeding of highly productive and heat tolerant livestock breeds. Further research should be conducted on characterization, identification of indigenous breeds at molecular level and on identification of responsible genes/genomic regions associated with thermoregulation, feed and production efficiency in order to develop suitable adaptive and mitigation strategies to counter environmental stresses.

This article links the concept of access and benefit-sharing as it pertains to crop genetic resources to climate change adaptation and argues that systems for access and benefit-sharing can, and should, be designed to contribute to climate change adaptation for agriculture. The access and benefit-sharing provisions of the two international agreements that together provide the international legal framework for access and benefit-sharing – the Convention on Biological Diversity (with its Nagoya Protocol) and the International Treaty on Plant Genetic Resources for Food and Agriculture – are presented and analysed. How these agreements are implemented is central to adaptation, as the effects of climate change threaten crop genetic resources and future adaptive capacity, and, if properly maintained and utilized, crop genetic resources will be essential to climate change adaptation across the globe. This article, therefore, argues that an important adaptation strategy linked to such implementation is to direct benefit-sharing for crop genetic resources towards adaptation efforts and to ensure facilitated and efficient access to crop genetic resources for adaptation purposes. Some options for how this can be pursued at both the international and national level are offered.
