| We explore the impact of forest policy reforms implemented in the early 1990s in Niger in the wake of the severe droughts that affected the Sahel in the 1970s and 1980s. We focus on Sahelian multiple-use forest ecosystems and set out to analyze policy-induced changes in the patterns of interactions between various uses, users, and dry-forest ecosystems, interactions that influence the effective management of rural forests. We put forward the hypothesis that the new forest policy reforms were designed according to a vulnerability diagnosis, highlighting two stressors: droughts and increased demand for firewood. This led to a single-issue policy focused on firewood provision and was implemented through the Household Energy Strategy (HES). The HES... |

| Payments for ecosystem services (PES) have increasingly been implemented to protect and restore ecosystems worldwide. The effectiveness of conservation investments in PES may differ under alternative policy scenarios and may not be sustainable because of uncertainties in human responses to policies and dynamic human-nature interactions. To assess the impacts of these interactions on the effectiveness of PES programs, we developed a spatially explicit agent-based model: human and natural interactions under policies (HANIP). We used HANIP to study the effectiveness of China’s Natural Forest Conservation Program (NFCP) and alternative policy scenarios in a coupled human-nature system, China’s Wolong Nature Reserve, where indigenous... |

| Shifting cultivation systems, one of the most widely distributed forms of agriculture in the tropics, provide not only crops of cultural significance, but also medicinal, edible, ritual, fuel, and forage resources, which contribute to the livelihoods, health, and cultural identity of local people. In many regions across the globe, shifting cultivation systems are undergoing important changes, one of the most pervasive being a shortening of the fallow cycle. Although there has been much attention drawn to declines in crop yields in conjunction with reductions in fallow times, little if any research has focused on the dynamics of noncrop plant resources. In this paper, we use a data set of 26 fields of the same age, i.e., ~1.5 yr, but differing in the... |

| Neste trabalho esta sendo proposto o desenvolvimento de alternativas tecnologicas que permitam o manejo sustentado da vegetacao da caatinga, com o objetivo de evitar a degradacao ambiental e promover a recuperacao da produtividade agricola e pecuaria em niveis economicos e ecologicos. A manipulacao da vegetacao, atraves do raleamento, do rebaixamento, do raleamento-rebaixamento e do enriquecimento, pode aumentar a disponibilidade de forragem em ate 800% e a producao animal em ate 1500%. A sustentabilidade da producao agricola em condicoes tropicais sera obtida com sua fixacao, substituindo-se as praticas atuais de manejo da pecuaria, tais como o banco rocado. O manejo da vegetacao da caatinga com vistas a obtencao de produtos nao madereiro, ainda e... |
