    • SYNERGIES BETWEEN ADAPTATION AND MITIGATION  Positive correlation between soil carbon and crop yield  Agricultural practices that improve soil fertility and enhance carbon sequestration also improve yield  Increased fertilizer application, ideally combining inorganic with organic soil fertility types  Increased and more efficient agricultural water management (reduces CO2 from fuel/electricity, conserves land)  Agricultural R&D, advisory services, and information systems support both adaptation and mitigation Page 14
    • TRADEOFFS BETWEEN ADAPTATION AND MITIGATION  Tradeoff between crop residues and animal feeds in parts of Kenya  Lack of application of labor-intensive soil & water fertility management practices on marginal soils (too costly/risky)  Increased fertilizer application (in conjunction with soil fertility management) reduces soil mining and supports mitigation and adaptation, over-fertilization increases GHG

    • CONCLUSIONS INTERNATIONAL FOOD POLICY RESEARCH INSTITUTE
    • CONCLUSIONS  Mitigation to climate change may yield substantial benefits for smallholder farmers in Kenya (US$2.2 billion in East Africa) that can be used to support adaptation and development efforts  Given the low price of carbon offsets (US$5- 20/ha) mitigation activities alone do not yield sufficient benefits: the latter need to be complemented by co-benefits from adaptation and increased productivity/profitability  Therefore it is essential to focus on activities that advance all three areas: profitability, adaptation, and mitigation
    • CONCLUSIONS  Changing crop varieties/types and planting dates are among the most common adaptive strategies at the farm level  The main constraint to implementing other adaptions is lack of access to capital and credit (ex.: irrigation is widely desired but expensive to establish and operate)  Some of the priorities for development identified by farmers (irrigation, extension, capacity building, etc.) will support the synergies of mitigation and adaptation to climate change
    • CONCLUSIONS  Farmers are aware of the connection between agriculture and climate change and of the benefits of planting trees to mitigate climate change  There is less awareness about the mitigation potential for soil and water conservation and integrated soil fertility management and their potential synergies with adaptation
