DOI: Climate change itself as a natural process but in recent years it will lead to changes in rainfall pattern, variation in temperature, sea level rises, increasing severity and various extreme weather events. Small landholder farmers Subsistence are unable to cope with such climatic hazards but there is a tremendous scope of expanding agroforestry. Climate change is well buffered, and resilience builds up by Agroforestry.

It is globally accepted that climate change is presently the greatest threat to the sustainability of human livelihood and biodiversity. Most farmers in the study area are highly aware of climate change and its consequences on the farming system; however, mitigation strategies are clearly lacking. Among the mitigation, mechanism to reduce the threat is achieved by increasing the amount of carbon sinks and reducing greenhouse gas emission through the adoption of agroforestry practices. The purpose of this study is to determine if awareness on climate change leads to the adoption of agroforestry practices, and to examine the determinants. A total number of questionnaires were administered to the farmers in the district using stratified random sampling technique.
Role of agroforestry in climate change mitigation
We test the hypothesis that agroforestry improves livelihoods and mitigates climate change in smallholder farming systems simultaneously. Data were collected using household surveys and standard biomass assessment approaches using locally relevant allometric equations. Summary statistics and regression analyses reveal linkages between on-farm carbon stocks and farm- and household characteristics. With an average of 4. Timber was considered the most important use of on-farm trees before firewood and construction material. The results suggest that gaining self-sufficiency in firewood is the most important benefit with on-farm carbon accumulation.

Agricultural Landscapes Under Changing Conditions based upon a national scientific assessment of agroforestry Figure 1. With contributions from more than 50 experts from the United States, Canada, and Mexico, this report presents the first-ever synthesis on agroforestry as a mechanism for improving the resiliency of agricultural lands under climate change. Figure 1. Chapters in the assessment include 1 Introduction, 2 Reducing threats and enhancing resiliency, 3 Greenhouse gas mitigation and accounting, 4 Valuation of agroforestry services, 5 Human dimensions of agroforestry systems, 6 Agroforestry resources, 7 Expanding the North American perspective—Canada, 8 Expanding the North American perspective—Mexico, and 9 Challenges and opportunities. Eight regional summaries were also developed to provide perspectives on the status and potential future role of agroforestry in each of the regions. The temporal scope of the literature search focused on the period of to , and the geographical scope focused on temperate agricultural regions. The references and abstracts are also available from an online Zotero TM database that will be updated as new literature becomes available.
Agroforestry not only helps in climate change mitigation but also climate change adaptation. It is an established fact that despite our present.
Overstory #255 - Climate Change Adaptation
Received 4 July ; revised 8 August ; accepted 19 August Despite its low emissions of greenhouse gasses GHGs , Sri Lanka is considered as a vulnerable small island nation under climate change. Agroforestry, which uniquely integrates trees into land use systems, has historically contributed to climate change adaptation in Sri Lanka. Hence, the promotion of agroforestry practices is vitally important to enhance the resiliency of the country to future climate change. This paper reviews the literature and discusses the adverse impacts of climate change on agriculture and forestry, the effects of adapting agroforestry on climate changes, and important policies for promoting agroforestry adaptation in Sri Lanka. The adverse impacts of climate change on agriculture and forestry are identified as follows: endangerment of natural assets; prevalence of pests, diseases and invasive species; agriculture and forest damage; and high levels of food insecurity. The adaptation of agroforestry impacts climate change by increasing the tree cover outside forests, enhancing forest carbon stocks, conserving biodiversity, reducing risks and damage intensity, maintaining health and vitality, and scaling up multiple benefits.
The potential of forests and trees to mitigate global warming has long been the main focus of climate change discussions. But forests — and the livelihoods of the 1. In fact, the ability of forests and trees to adapt to these impacts will influence their ability to mitigate climate change. Moreover, forests and trees provide so called nature-based solutions for adaptation helping other sectors build resilience. Thanks to their crucial ecosystem services, forests support crops, livestock, and fisheries, as well as prevent flooding and erosion that can threaten infrastructure, economies and people. A few years later, in , FAO issued the publication Addressing agriculture, forestry and fisheries in National Adaptation Plans — Supplementary guidelines , which introduces the sector perspective and opportunities on NAPs.
Agroforestry practices that are most common in North America include riparian forest buffers, windbreaks, silvopasture, alley cropping, and forest farming. Agroforestry can add a high level of diversity within agricultural lands and, with it, an increased capacity for supporting numerous ecological and production services that impart resiliency to climate change CC impacts see figure below Verchot et al. CC risk management is difficult in annual-only systems due to the increasing uncertainty and volatility of interannual variability in rainfall and temperatures. The mixing of woody plants into crop, forage, and livestock operations provides greater resiliency to this interannual variability through crop diversification produced seasonally, as well as through increased resource-use efficiency Olson et al. Agroforestry increases soil porosity, reduces runoff, and increases soil cover, which can improve water infiltration and retention in the soil profile thereby reducing moisture stress in low rainfall years Jose et al. During periods of excessive soil moisture, treebased systems can maintain aerated soil conditions by pumping out excess water more rapidly than other production systems, and when flooding eliminates an herbaceous crop for a season, the woody component can often survive and offer an economic return Dimitriou et al.
Climate change is projected to increase global temperatures, which could affect the agricultural growing season and increase drought Noble et al.
