“…The accuracy assessment measures how many ground truth pixels were classified correctly. Accurate information on land use land cover changes and the forces and processes behind is essential for designing sound environmental policies and management (Minale, 2013). Accuracy assessment is very important for understanding the classification results and employing these results for decision-making (Lu et al, 2003).In this study, the classification accuracy for recent LUCC map was carried out using ground control points from field observations as the major sources of reference data and set of reference points.…”

Assessing and quantifying the current forest resources status underpins sustainable forest resources planning and management. To this end, this study was conducted to analyze the dynamics of land use cover change (LUCC) and explore their drivers at the central highlands of Dry Afromontane Chilimo-Gaji forest for the study period (1973-2015) under consideration. The result of the study indicated that landscape trends have occurred in Chilimo-Gaji forest over the last 43 years and five classes of LUCC namely shrub land, rural settlement, bare land and road, forest land and agricultural land were identified. The most commonly reported drivers of deforestation in the study area were expansion of agricultural land, rural settlements, population growth, insecurity of the tenure and rights over the land, timber production and fuel wood collection. Surprisingly, the increasing demand for agricultural land and human settlement for increasing human population underpinned by expansion of agricultural activities led to the clearing of forest land in the study area. The study reveals that the forest land cover type has lost 922.14 hectares (26.96 %) which were changed into other land cover types such as agriculture and settlement for the study period under consideration with an annually rate of 21.45 ha. However, deforestation rates showed declining trend between the time periods 2008-2015 as a result of introduction of Participatory Forest Management (PFM) schemes (1996) which involve the local community in management and sharing of the benefit obtained from the management. In order to promote sustainable forest resources management in the study area in the years to come, integrated land use planning and management and addressing key drivers of deforestation were recommended.

“…The pattern of national development shows changes in land use planning which causes a reduction in the area of open spaces or green land cover. The uncontrolled land conversion beyond their carrying capacity can threaten sustainability of natural environment, agriculture production, food security and cause socio-economic losses [3]; [4]; [5]; [6]; [7]; 8]; [9].…”

Evaluation of the environmental carrying capacity should be measured as part of sustainable land use planning. One of methods to evaluate this carrying capacity is land capability evaluation.. This study aims to evaluate the suitability of landuse in each of land capability classes in Mojokerto Regency. Land capability is obtained by spatial analysis and overlay of several criteria for land capability, included soil texture, effective soil depth, drainage, land slope, and soil erosion. The description of actual landuse is obtained using landsat 8 OLI images at coverage time in May 2018. The results of study show that the land capability in Mojokerto Regency varies from Class I to Class VIII. The actual land use in Mojokerto Regency are about 98% or 95314.33 Ha are suitable to the land capability, and 2% or of 2078.67 Ha are unsuitable to the land capability. Based on the environmental carrying capacity, about 78.85% or 76798.89 Ha of land in Mojokerto Regency are allocated accordingly, and 0.90% or of 875.29 Ha of land are allocated beyond their carrying capacity, 19.39% or 18884.18 Ha of land are allocated in a conditional manner so it needs any specific treatments of landuse.

“…Cyprus papyrus, the characteristic plant species of the wetlands, has dramatically declined, with even local extinctions in some areas [38]. Consequently, many wetlands in the lake catchment are shrinking at a drastic rate [43,[56][57][58], (Table 2). This is an indication that the wetlands in the lake catchment are not wisely utilized in line with the Ramsar Convention.…”

A Drivers-Pressure-State-Impact-Responses Framework to Support the Sustainability of Fish and Fisheries in Lake Tana, Ethiopia

et al. 2018

Lake Tana, Ethiopia's largest lake, has a remarkable and conservation-worthy assemblage of fish species, requiring fisheries management for sustainable exploitation. However, due to anthropogenic impacts, many of these fish species are threatened. Hence, an improved management of these resources is recommended. To allow a more sustainable exploitation of natural resources, a better understanding of the cause-effect relationships between anthropogenic impacts and environmental components is fundamental. The Drivers-Pressure-State-Impact-Responses (DPSIR) framework is a useful tool to describe these links in a meaningful way to managers and policy makers. Despite its potential, application of DPSIR is virtually lacking in developing countries. This paper assessed the potential of the DPSIR framework and used it to comprehensively describe the available knowledge and management needs in the lake catchment. Rapid population growth and the economic transformation are the main driving forces leading to various pressures such as water quality and wetlands degradation as well as declining fish community, which is detrimental to the socio-economic state and health of the local inhabitants. As feedback to the driving forces, pressures, state changes and impacts, optimal multi-level responses are developed. This study aims at providing policy makers a better understanding of the lake catchment in order to bridge the gap between science and decision-making.
