2. Green Economy What is the Green Economy? The “green economy” refers to economic sectors that are focused on environmental sustainability. The green economy seeks to address the interdependence of human economic development with the health of the natural ecosystem.

3. MANUSIA KHALIFAH DI MUKA BUMI ''Ingatlah ketika Tuhanmu berfirman kepada para Malaikat: ''Sesungguhnya Aku hendak menjadikan seorang khalifah di muka bumi.'' Mereka berkata: ''Mengapa Engkau hendak menjadikan (khalifah) di bumi itu orang yang akan membuat kerusakan padanya dan menumpahkan darah, padahal kami senantiasa bertasbih dengan memuji Engkau dan mensucikan Engkau?''. Tuhan berfirman: ''Sesungguhnya Aku mengetahui apa yang tidak kamu ketahui'‘ (Al-Baqarah:30)

17. Sustainable Water Management: SWM • SWM is based upon the principles , namely: • Freshwater is a finite and valuable resource that is essential to sustain life, the environment and development. • 2. The development and management of our water resources be based on a participatory approach, involving users, and policy makers at all levels. • Women play a central role in the provision, management and of water resources. • Water has an economic value and should therefore be seen as an economic good.

18. Water's vital role for the environment and humans is linked to five main functions : 1. Maintaining human health : clean water is essential for maintaining human health; 2. Maintaining environmental health: the health of aquatic ecosystems is essential for fish/seafood supply, is a major determinant of biodiversity, and provides for many other vital goods and services; 3. Supporting two production functions : a) biomass production, necessary for the supply of food, fuel wood and timber; and b) economic production, since industrial development has traditionally been "lubricated" by easy access to water; 4. Supporting two carrier functions : a) water plays an active role in diluting and transpiration wastes; and b) in the natural erosion and land processes of the global water cycle; 5. Psychological function, which makes water bodies, water views, fountains and so on fundamental components of human preferences and desires. Water also plays a role in many religions and cultural activities.

19. SUMBER AIR : HUJAN "Dan Yang menurunkan air dari langit menurut kadar (yang diperlukan) lalu Kami hidupkan dengan air itu negeri yang mati, seperti itulah kamu akan dikeluarkan (dari dalam kubur)." (Al Qur'an, 43:11) Diperkirakan dalam satu detik, sekitar 16 juta ton air menguap dari bumi. Angka ini menghasilkan 513 trilyun ton air per tahun. Angka ini ternyata sama dengan jumlah hujan yang jatuh ke bumi dalam satu tahun.

20. RAIN WATER Al A’raaf : 57. Dan Dialah yang meniupkan angin sebagai pembawa berita gembira sebelum kedatangan rahmat-Nya (hujan); hingga apabila angin itu telah membawa awan mendung, Kami halau ke suatu daerah yang tandus, lalu Kami turunkan hujan di daerah itu, maka Kami keluarkan dengan sebab hujan itu pelbagai macam buah-buahan. Seperti itulah Kami membangkitkan orang-orang yang telah mati, mudah-mudahan kamu mengambil pelajaran.   Al Furqoon : 50. Dan sesungguhnya Kami telah mempergilirkan hujan itu diantara manusia supaya mereka mengambil pelajaran (dari padanya); maka kebanyakan manusia itu tidak mau kecuali mengingkari (nikmat).

21. Green water is a very important resource for global food production. About 60% of the world staple food production relies on …  green water. The entire meat production from grazing relies on green water, and so does the production of wood from forestry. In drylands almost the entire food production depends on green water (the relative importance of irrigation is minor) and most of the industrial products, such as cotton, tobacco, wood, etc. Pengelolaan Air Hijau

24. Green water is ignored … by engineers because they can't pipe or pump it, by economists because they can't price it, and by governments because they can't tax it. www.fao.org/docrep/R4082E/r4082e03.htm

25. KREDIT AIR HIJAU Green water credits, however, are an opportunity to address this disparity while enhancing ecosystem services for both farmers and downstream stakeholders. The International Soil Reference and Information Centre (ISRIC) is pioneering green water credits, which it describes as: A mechanism for direct payment to people in rural areas in return for water management activities which are presently un-recognized and unrewarded. Benefits to poor people drive this initiative which, at the same time, safeguards water resources and food security for everyone. With funding from the Swiss Agency for Development and Cooperation (SDC) and the International Fund for Agricultural Development (IFAD), ISRIC is developing a proof-of-concept project that creates financial incentives for farmers in the developing world to better manage green water.

26. KREDIT AIR HIJAU • ISRIC is taking three steps to implement green water credits: • 1. Quantification of the resource and how it can be optimized by land use and management; • 2.Valuation of its various uses and the costs of floods, sedimentation, and the diseases caused by a lack of clean water – enabling benefit cost analysis; • 3. An agreed mechanism to: • Specify optimum management and its water benefits;b. Negotiate a fair price;c. Establish that the work is done;d. Collect and pay credits.

27. MEMANEN HUJAN Rainwater harvesting is the gathering, or accumulating and storing, of rainwater. Rainwater harvesting has been used to provide drinking water, water for livestock, water for irrigation or to refill aquifers in a process called groundwater recharge. Rainwater collected from the roofs of houses, tents and local institutions, or from specially prepared areas of ground, can make an important contribution to drinking water.

28. Here, you do this. It involves trees! Here, you do this! It involves agriculture! Forestry Agriculture Agroforestry incorporates technology from agriculture and forestry. Both areas of expertise are needed, neither can be ignored if an agroforestry system is to provide the desired benefits.

29. We group agroforestry practices in five categories: Alley cropping, Silvopasture, Forest farming, Riparian forest buffers, and Windbreaks.

30. ALLEY CROPPING

31. Alley Cropping Alley cropping systems provide a way to lower risk by diversifying production. In alley cropping an agricultural crop is grown simultaneously with a long-term tree crop to provide annual income while the tree crop matures. Fine quality hardwoods like walnut, pecan, and oak are preferred species, and can produce high-value lumber or veneer logs. When nut-bearing trees are used they can provide an intermediate product for sale. In addition to improving annual cash flow, these systems also protect annual crops, reduce soil erosion, and provide wildlife habitat. Most row crops and grains have been shown to grow well in an alley cropping system.

32. MANFAAT ALLEY CROPPING • Diversify farm enterprise • Reduce erosion • Improve water quality • Protect crops • Improve utilization of nutrients • Enhance wildlife habitat • Improve aesthetics • Store carbon

49. Sustainable AgroForest Management : SAM AgroForestmanagement is the branch of forestry concerned with the overall administrative, economic, legal, and social aspects and with the essentially scientific and technical aspects, especially silviculture, protection, and forest regulation. This includes management for aesthetics, fish, recreation, urban values, water, wilderness, wildlife, wood products, agroforestgenetic resources and other agroforestresource values . Management can be based on conservation, economics, or a mixture of the two. Techniques include timber extraction, planting and replanting of various species, cutting roads and pathways through agroforests, and preventing fire.
