Climate change is no longer merely projected to occur in the indeterminate future. It has already begun to be manifested in the weather regimes affecting agroecosystems, food production, and rural livelihoods in many regions around the world. It is a real and growing challenge to the world at large and in particular to the scientific community, which is called upon with increasing urgency to respond effectively.The second volume in the ICP Series on Climate Change Impacts, Adaptation, and Mitigation, Handbook of Climate Change and Agroecosystems: Global and Regional Aspects and Implications is

This book takes both a global as well as a local perspective in assessing the impacts of climate change on the economy, agricultural sector, and households in three of the MENA countries; Syria, Tunisia and Yemen. The major channels of impact for global climate change are through changing world food (and energy) prices, especially since all the countries under analysis are or have become net importers of oil and petroleum products and many food commodities in recent years. The impacts of local climate change decrease crop yields in the longer run and through them, productivity in the agricultu

If not addressed in time, climate change is expected to exacerbate Nigeria’s currentvulnerability to weather swings and limit its ability to achieve and sustain the objectivesof Vision 20:2020 [as defined in http://www.npc.gov.ng /home/doc.aspx?mCatID=68253].The likely impacts include:• A long-term reduction in crop yields of 20-30 percent• Declining productivity of livestock, with adverse consequences on livelihoods• Increase in food imports (up to 40 percent for rice long term)• Worsening prospects for food security, particularly in the north and the southwest• A long-term decline in GDP of up to 4.5 percentThe impacts may be worse if the economy diversifies away from agriculture more slowlythan Vision 20:2020 anticipates, or if there is too little irrigation to counter the effects ofrising temperatures on rain-fed yields. Equally important, investment decisions made on the basis of historical climate may bewrong: projects ignoring climate change might be either under- or over-designed, withlosses (in terms of excess capital costs or foregone revenues) of 20-40 percent of initialcapital in the case of irrigation or hydropower.Fortunately, there is a range of technological and management options that make sense,both to better handle current climate variability and to build resilience against a harsherclimate:• By 2020 sustainable land management practices applied to 1 million hectares can offsetmost of the expected shorter-term yield decline; gradual extension of these practices to50 percent of cropland, possibly combined with extra irrigation, can also counter-balancelonger-term climate change impacts.• Climate-smart planning and design of irrigation and hydropower can more than halvethe risks and related costs of making the wrong investment decision.The Federal Government could consider 10 short-term priority responses to buildresilience to both current climate variability and future change through actions toimprove climate governance across sectors, research and extension in agriculture,hydro-meteorological systems; integration of climate factors into the design of irrigationand hydropower projects, and mainstreaming climate concerns into priority programs,such as the Agriculture Transformation Agenda.
