WHAT IS THIS DIDACTIC TOOLKIT FOR, The main objective of this methodological toolkit is to aid farmers and technicians to. better understand the principles and or mechanisms that underlie the resiliency or. lack thereof of farming systems and how agroecological management can enhance the. capacity of farmers to adapt to unpredictable and severe climatic variability. The tool allows users to better clarify their perceptions of climate change use indicators. to assess the vulnerability of their farms and improve their ecological resiliency via. agroecological interventions that enhance the adaptive response capacity of farmers. The toolkit can be used for, a Conducting a rapid agroecological assessment of farms and their level of.
vulnerability, b Initiating a process of agroecological conversion to enhance the response capacity. of farmers and thus improve the resiliency of their farming systems. c Monitoring the trajectory of the farms under agroecological conversion after. climatic events such as hurricanes rain storms and or drought. SOME BASIC PRINCIPLES AND CONCEPTS, What Are Vulnerability Vulnerability is determined by the bio. physical features of the farm and the, And Resiliency socio economic conditions of farmers that. enhance or reduce the exposure to the,Resilience is defined as the ability of a threat. farming system to absorb disturbances and, adapt to stress and change while retaining Threat is the climatic event s intensity.

Thus a resilient agroecosystem would i e yield losses due to storm or drought. be capable of providing food production, when challenged by severe drought or by Response capacity is the ability or lack. excess rainfall Conversely vulnerability thereof of the farming systems and the. can be defined as the possibility of loss farmers to resist and recover from the. of biodiversity soil water or productivity threat depending on the level of social. by an agroecosystem when confronted organization and the agroecological. with an external perturbation or shock features e g crop diversity of the farms. Vulnerability refers to the degree to which a, system is susceptible to and unable to cope In summary for an event to be considered. with adverse effects of climate variability a risk depends on whether in a particular. and denotes a state of susceptibility to region there is a community that is. harm from exposure to stresses associated vulnerable to it In order for the event to. with environmental change due to the become a threat there should be a high. absence of capacity to adapt Folke 2006 probability that it will occur in that region. and for the threat to be devastating will, When exposed to climate change the depend on the magnitude of the event and. resulting risk endured by a farm is the the level of vulnerability of the community. product between threat vulnerability and Such vulnerability can be reduced by. response capacity as described in Altieri et the response capacity determined by. al 2015 the agroecological features of the farms,and the management strategies used by. farmers to reduce climatic risks and to resist, Risk Vulnerability Threat and recover from such events Therefore.
