Brazil has committed to reducing deforestation in the Amazon and has identified target goals for 2020. A variety of environmental policies and tools are used to reduce deforestation in the region, including payments for ecosystems services (PES). This report analyzes whether payments for ecosystem services are a viable option for supporting conservation and socio-economic goals in the Amazon. PES schemes provide economic incentives in exchange for meeting an environmental goal. They have been relatively successful in developed countries but have had limited applications or success in developing contexts. This report identifies the agents and activities that drive deforestation in the Brazilian Amazon and determines which of these may be suitable for PES applications. It also provides a framework for analyzing current PES schemes in order to draw out best practices and lessons learned which may be applied to future program. PES schemes do have a role to play as one of the tools used in addressing deforestation in the Amazon. They can be cheaper than indirect approaches but do face some challenges in evaluation. Future PES applications may benefit from the lessons learned in the early applications of these programs. / text

Įvairaus pobūdžio atsiskaitymai versle naudojami jau tūkstančius metų ir yra seni, kaip ir pats verslas. Šiuo metu susiklosčius sudėtingai ekonominei situacijai, problemos užgriuvo ir ant verslininkų pečių. Lietuvoje, „Creditinfo“ duomenimis, kas antra įmonė turi pradelstų įsiskolinimų. Laiku nepadengiami įsiskolinimai daro nemažą žalą: trukdo įmonei vykdyti tiesioginę veiklą, kenkia tiek įmonės, tiek viso verslo įvaizdžiui. Akivaizdu, kad plėtojantis informacinėms technologijoms, turi atsirasti naujų priemonių ir būdų, kurie padėtų verslui spręsti susidariusias problemas. Šiame darbe ya nagrinėjami įvairūs atsiskaitymo būdai, jų sistemos, e.parašas ir jo panaudojimo galimybės. Nustatyta, kad e.parašas yra tinkama priemonė naudoti atsiskaitymuose. Darbe sudarytas saugių tarpusavio atsiskaitymų modelis, ištirtos jo realizavimo ir panaudojimo galimybės.Gauti rezulatatai rodo e.dokumentų sistemos privalumą prieš standartines sutartis. / Business subjects have been using different types of payments for many years. But some problems persists too. One of them is debt. It makes companies to have difficulties doing settlements with other companies, makes bad reputation for companies and bushiness on the whole. In nowadays many new technologies are raised, which can be used in many spheres. So in the business too.One of them is e-signature. But the research showed that most of payments systems still don‘t use it. In this work safe inter-payments system was projected and suggested. It includes model of debt circles finding, identification and authority, circulation of e-documents. The examination of debt reseting module showed that this task needs much computers resources. Otherwise, the fact that such system can reduce contracts signing time is obvious too. In conclusion, similar systems could and should be developed in the future.
