“…Degraded forest is a forest type in which most or all of the commercial timber has been removed by conventional logging. Almeida et al (2020) reveal that there is an increase of 15% from 1991 to 2013 of degraded forest in the Moju region, due to the ongoing effects of fires and unregulated logging activities. Forest degradation leads to impoverishment of the forest in terms of biodiversity and carbon stocks, and it is thus important that it be evaluated.…”

“…Arauaí river basin follows the deforestation rate of the Moju municipality, showing conversion of forests to agricultural areas (Almeida & Vieira, 2014). In fact, dramatic increase of deforestation in Moju region from 1991 to 2013 leads to 50% of forest loss and reflects the substitution of this vegetation by expanding oil palm plantations and ranching operations (Almeida et al, 2020).…”

“…This basin is subject to intense pressures on its natural resources and land use (Almeida & Vieira, 2014), dominated by different agricultural uses, isolated fragments of native vegetation, secondary vegetation, and areas under degradation process (Silva et al, 2016). Ongoing degradation of this region leads to the increasing fragmentation, isolation and reduction of the forest remnants (Almeida et al, 2020).…”

This study aimed to identify priority areas for the passive restoration of the Arauaí river basin, municipality of Moju, Pará, using a multicriteria model. This basin is located in a region with intense land use dynamics and expansion of oil palm cultivation, and with high forest loss and fragmentation. The Weighted Linear Combination method was used, with the aggregation of five criteria (Natural Erosion Vulnerability, Potential Land Use and Cover to Passive Restoration, Proximity to the Primary Forest, Forest cover deficit in PPAs, and Distance from Roads and Highways). This analysis allowed to evaluate different biophysical classes and types of land use that affect the selection of areas for restoration. A total of 207.82 km² of priority areas for passive restoration were identified in the studied basin, with about 80% of its priority areas having medium to very high priority. The final map generated proved to be a useful instrument in the environmental management of restoration plans in the Amazon watershed.

“…This is despite concerted attempts by human beings to promote environmental protection and ecological restoration through behavioral stimuli aimed at rational actions and interventions [42,43]. Hypothetically, in order to unify nature and human interactions, it is important to synthesize local community perceptions of landscape change and its drivers with the broader sustainable environmental planning and management requirements [41,[44][45][46][47][48][49]. Therefore, a study that investigates landscape changes and the possible drivers and effects from the perspective of socio-psychological or community perception is particularly desirable in South Africa.…”

Landscape-change studies have attracted increasing interest because of their importance to land management and the sustainable livelihoods of rural communities. However, empirical studies on landscape change and its drivers are often poorly understood, particularly, in small rural communities in developing countries such as South Africa. The present study surveyed local community livelihoods and perceptions of landscape change in the Nzhelele and Levuvhu river catchments in Limpopo Province, South Africa. These areas have experienced land reform and are also characterized by environmental degradation, poverty, inequality and environmental justice concerns among other issues. Land-cover maps derived from Landsat satellite imagery were used for purposes of correlating and validating the survey data findings and results. The survey results showed that education levels, working status and marital status have statistically significant effects on community livelihoods (indicated by levels of income, p < 0.05). Maize, fruits and vegetables are the main cultivated crop varieties in the study area, and these crops are mainly used for subsistence to meet household self-consumption requirements. Moreover, local community members and stakeholders argue that the landscape has changed over the past 20 years mainly as a result of urban expansion, deforestation, agricultural diversification and forestry intensification. These landscape changes were largely confirmed by the land-cover change maps derived from satellite imagery. Soil erosion as a result of landscape changes was identified as a major threat and hazard in the study area. Political, natural, economic and cultural factors have been identified as the major underlying drivers for the observed landscape changes. These results have implications for understanding landscape change, coupled with human–nature relationships as well as informing government policy with respect to advancing land management and further promotion of the sustainable livelihoods of rural communities. Overall, the study proposes a multiple stakeholders’ approach and ecosystem-based approach to promote the sustainable management of landscapes in rural areas.

“…Agriculture, especially the cultivation of oil palm has been seen as one of the most important causes of climate change (Hasanah, Komarudin, Dray & Ghazoul, 2019). Agriculture does not only convert large expanses of forests into monoculture plantations, but also as a great emitter of Green House Gases (GHG) emission into the atmosphere (deAlmeida, Vieira, Silvio, & Ferraz, 2020). Cameroon is ranked 62 nd among emitters of Green House Gases in the world.…”

Planting material or seed is the most determinant factor for oil palm productivity alongside agro climatological and management considerations. A study was conducted to determine the different varieties of oil palm planted in smallholders’ plantations, the distribution channels for oil palm seeds and all the actors involved in the seed trade sector in Cameroon. This is a bid to secure the supply of only improved planting materials to smallholder farmers. 230 oil palm smallholder plantations were surveyed and individual palms were subjected to varietal determination. The Chi-Square Test (c2) for Fixed Ratio Hypothesis (= 0.05) was used to determine whether the observed ratio deviates significantly from the Mendelian hypothesized genetic segregation ratio. Up to 65% of smallholder farms were found to be planted with poor planting material distributed in the different Mendelian ratios; 100% Dura, 50% Tenera and 50% Dura (1:1), 25% Dura, 50% Tenera and 25% Pisifera (1:2:1). The source of this poor quality planting material for these farms was deduced to come from private nursery entrepreneurs and workers of industrial plantations such as the Cameroon Development Corporation (CDC), Cameroon Palm Oil Company (SOCAPALM), Common Initiative Groups (CIG’s) and Non-Governmental Organisations (NGO’s). Farmers supplied by government services especially the Ministry of Agriculture and Rural Development and some of its specialized development projects all received good quality material. Thus, this is the only means now available which can assure the distribution of seeds good quality seeds
