The settlements are located in areas with sandy soils and highly degraded by human action Moreover, the region is considered marginal for the production of coffee, because it is subject to periods of high temperatures, prolonged drought and frost risk, which hinders the sustainability of farms. The environmental and socioeconomic impacts of agroforestry are analyzed through Ambitec-agro system, consisting of a set of indicators aimed at ex-post evaluation of the contribution of technological innovation to environmental, social and economic development of an agricultural activity. The system Ambitec involves： （1） general data collection about the technology; （2） application of questionnaires with adopters selected and insertion of data on impact indicators spreadsheets via platform MS-Excel and to obtain quantitative results and impacts partial indexes and aggregates the impact of technology selected; （3） analysis and interpretation of indices obtained, which vary between -15 and 15. The results indicate that agroforestry management can contribute to： （1） maintaining or increasing the sustainability of traditional coffee-growing regions in the case of sudden climate change; （2） the expansion of the coffee regions now considered unsuitable for the cultivation of coffee; （3） for sustainable regional development.展开更多

The increasing population, urbanization, land-use changes, and the climate significantly affect coupled natural and human systems and threaten environments and socio-ecological land systems. The degradation of drylands poses a severe and widespread threat to the lives of millions of people, especially in developing countries and in the global environment. This review assesses published literature on dryland socio-ecological systems to reveal current research trends and changes in research themes over time and introduces basic theories and advances in dryland socio-ecological system frameworks, resilience measurement, and regime shifts. Developing a more general but adaptable framework and a more practical strategy for long-term coordination and partnership and attaining specific insights into ecological services should receive more attention and be strengthened in future studies on drylands sustainability.展开更多
