“…Relevant studies on forest dynamics in a changing climate, its roles, drivers, policies, and reliable methods for their monitoring are duly undertaken using different approaches. While some of them are based on simple remote sensing e.g., [13][14][15][16][17][18][19], others have investigated the intensity analysis e.g., [20][21][22][23]. Though previous studies integrated remote sensing and household surveys to investigate landscape dynamics e.g., [24,25], little is known about the approach in Togo.…”

This study investigates proximate drivers of cropland and forest degradation in the Kloto district (Togo, West Africa) as a way of exploring integrated sustainable landscape approaches with respect to socioeconomic and environmental needs and requirements. Net change analysis of major cash and food crops based on Landsat data from three time steps (1985-2002, 2002-2017, and 1985-2017) and quantitative analysis from participatory survey data with farmers and landowners are used. The study underlines poor agricultural systems and cassava farming as major factors contributing to the alarming forest losses between 1985 and 2017. A significant net loss in forest cover of 23.6% and areas under maize and cocoa agroforestry farming of 12.99% and 10.1% between 1985 and 2017, respectively, was noted. These significant losses are due to intensive cassava cropping (38.78%) and settlement expansion (7.87%). Meanwhile, the loss of forest cover between 2002 and 2017 was marginal (8.36%) compared to the period 1985-2002, which had a considerable loss of 15.24%. Based on participatory surveys, the majority of agricultural lands are threatened by erosion or physical deterioration (67.5%), land degradation or salt deposits and loss of micro/macro fauna and flora (56.7%), declines in soil fertility (32.5%) and soil water holding capacity (11.7%), and changes in soil texture (3.3%). Most farmers adhere to the proposed climate smart practices, with an emphasis on cost-effective drip irrigation systems (45.83%), soil mulching (35%), and the adoption of drought-resilient varieties (29.17%) to anticipate adverse spells. We conclude that low adoption of improved soil conservation, integrated water management, and harvesting systems and the use of less productive and adaptive cultivars entail extreme degradation of cropland and a decline in crop productivity. Consequently, farmers are forced to clear more forest in search of stable and healthy soil to meet their food demands and improve their livelihood. Capacity building on integrated pathways of soil and land management practices is therefore needed to ensure sustainable and viable socio-ecological systems at a local scale.

“…Landuse is a product of interaction between a society's cultural background, state and its physical needs on the hand an the natural potential of land on the other (Balak and Kolarkar, 1993 in Rawat et al, 2013). Landcover is defined by the attributes of the earth's land surface captured in the distribution of vegetation, water, desert and ice and the immediate subsurface, including biota, soil, topography, surface and groundwater and it also includes those structures created solely by Butt et al, 2015).…”

Oil and gas industry are an expensive industries, high risk and high technology. The exploration of oil and gas activities has not always been without some ecological side effects. Therefore the Environmental Baseline Assessment (EBA) needs to be done before the starts of oil and gas activities. An EBA helps to understand existingenvironmental conditions thus defining the focus of the environmental impact analysis and resources that need protection through appropriate and viable mitigation measures. The EBA consists both desktop studies and fields surveys. The desktop studies comprise the collection and evaluation of existing data, studies and reports already gathered and available through local government and nongovernmental organisations. The field surveys comprise observations and registration, collection and analysis of samples. The study process entails a scoping exercise by multi-disciplinary group of experienced specialists for the key environmental issues. Based on the valued ecosystem components, the study scope should cover, but not limited to issues such as climatic conditions, drainage and water resources, soils, flora, fauna, air quality, noise, land use, land tenure and socioeconomic aspects. The results of this study provide an overview of the condition of oil and gas areas both the physical environment, biological and chemical. Mapping land use and infrastructure will also be taken into consideration in the mobilization tool and emergencies. Another results are to provide an overview potential conflicts with other activities, spatial plans, conservation areas and population concentration. It can be used as a basis for good planning and mitigation. Impact arising from oil and gas activities could be physical, chemical, biological and socio-economic impacts. With such potential impacts, impact prediction can be analysis from the results of EBA. The other results of EBA is sensitivity area and called Environmental Sensitivity area. It is a reflection of ecological, social economic and sociacultural entities of certain area and comonly used to set response priority of environmental damage in oil and gas activities.
