Climate change, loss of biodiversityand ecosystem degradation
• Climate change, loss of biodiversity and ecosystem degradation are environment, development and security issues, i.e., they undermine:
• food, water and human security• the economy (loss of natural capital)• poverty alleviation and the livelihoods of the poor• human health• personal, national and regional security
• Climate change and ecosystem degradation are inter-and intra-generational equity issues:
• developing countries and poor people in developing countries are the most vulnerable
• the actions of today will affect future generations

Food SecurityFood SecurityDrivers of the recent increase in food pricesDrivers of the recent increase in food prices• Poor harvests due to variable weather - possibly related to
human-induced climate change• Increased use of biofuels• Increased demand , especially for meat• High energy prices, hence higher fertilizer prices• Speculation on the commodity markets• Export bans from some large exporting countries
The future ChallengeThe future Challenge• The demand for food will double within the next 25-50 years,
primarily in developing countries, and the type and nutritional quality of food demanded will change
• We need sustained growth in the agricultural sector to feed the world, enhance rural livelihoods and stimulate economic growth, while meeting food safety standards

Water Security
The Global Water CrisisWater scarcity is growing - by 2025 more than half of the world’s population is projected to live under conditions of severe water stress
Water quality is declining in many parts of the world
70% of all freshwater is used for irrigation - 15 - 35% of irrigation withdrawals exceed supply rates and are therefore unsustainable
50-60% of wetlands have been lost
Water has the lowest rate of cost recovery among all infrastructure sectors (about 20%)
Human-induced climate change is projected to decrease water quality and availability in many arid- and semi-arid regions, and increase the threats posed by floods and droughts in most parts of the world
