offsets – the fossil ec<strong>on</strong>omy’s new arena of c<strong>on</strong>flict 249implying that plantati<strong>on</strong>s could start competing aggressively for landthat might otherwise be given over to sec<strong>on</strong>dary regenerati<strong>on</strong> andc<strong>on</strong>servati<strong>on</strong> of native forest.In additi<strong>on</strong>, because CDM forestry projects, for ec<strong>on</strong>omic reas<strong>on</strong>s,would probably have to cover 1000 hectares and upwards (see below),they could well threaten the land tenure of people carrying out otherforest projects in Costa Rica. The average landholding in the countryis less than 50 hectares, with most parcels bel<strong>on</strong>ging to families.Well, sacrifi ces do have to be made for the climate, d<strong>on</strong>’t they?Ir<strong>on</strong>ically, <strong>on</strong>e of the things that the Costa Rican case helps show isthe impossibility of determining whether the climate would in factbenefit from a policy of pushing such projects. It also clarifies theproblems of fulfilling the c<strong>on</strong>diti<strong>on</strong>s set out in the Kyoto Protocol 48for reforestati<strong>on</strong> and forestati<strong>on</strong> carb<strong>on</strong> projects.Take, for example, a study <strong>on</strong> carb<strong>on</strong> projects d<strong>on</strong>e by the Forestand Climatic <strong>Change</strong> Project (FCCP) in Central America, jointlyexecuted by the Food and Agriculture Organizati<strong>on</strong> of the UN andthe Central American Envir<strong>on</strong>mental and Development Commissi<strong>on</strong>(CCAD). 49 The study shows that available soil use maps are notprecise enough to show how carb<strong>on</strong> storage in prospective carb<strong>on</strong>sink areas (or ‘Kyoto areas’) has changed since the 1990s, and are alsohard to compare with each other. That would make accounting forincreased carb<strong>on</strong> storage over the period impossible.The study also suggests that it would be impossible to show to whatextent Kyoto carb<strong>on</strong> projects were additi<strong>on</strong>al to ‘those that the countryimplements as part of its forestry development projects’: ‘it is not possibleto predict in what exact proporti<strong>on</strong> these activities will be in orout of the Kyoto areas and any assumpti<strong>on</strong> in this respect is enormouslyuncertain’. In additi<strong>on</strong>, Kyoto carb<strong>on</strong> projects could find it hard to factorout the anthropogenic activities to encourage natural seed nurseriesthat are being promoted and funded without carb<strong>on</strong> finance.Above all, the FCCP study reveals the c<strong>on</strong>fl ict between c<strong>on</strong>venienceand accuracy in measuring carb<strong>on</strong>. Measurements of soil carb<strong>on</strong> beforeand after the start of any carb<strong>on</strong> forestry project, it says, wouldbe too costly, even though such measurements are a key to carb<strong>on</strong> accountingfor plantati<strong>on</strong>s, which disturb soil processes c<strong>on</strong>siderably. 50Similarly, the study accepts for c<strong>on</strong>venience a blanket carb<strong>on</strong> storagefigure of 10 t<strong>on</strong>ne per hectare for grassland sites that could be c<strong>on</strong>vertedto carb<strong>on</strong> forestry. However, Costa Rica boasts too wide a varietyof grasslands and agricultural systems – most of them comprisinga lot of trees – for such a figure to be used everywhere. 51
