Land cover change in any ecosystem vary in space and time. The study analyzed spatial-temporal land cover change to predict forest degradation pressure points in Eastern Mau Forest Reserve. The study objectives were to determine types and amount of spatial-temporal land cover change; land cover change drivers and; forest resources use sustainability. The study used mixed sample survey design involving purposive sampling of spatial data and cluster sampling of forest resource use data. Primary data included ground control points, field validation data and forest resource use data. Secondary data included Landsat imagery, forest and administration boundaries and settlements data. Analysis was done for 1986-2014 period using Remote Sensing and Geographical Information System. The analysis techniques used included object based image segmentation and classification, accuracy assessment and land cover change detection. Land cover types in Eastern Mau Forest consisted of indigenous forest, shrubland, grassland, plantation forest, cultivated fields, bare ground and built-up area. The analysis results depicted that cultivated fields coverage increased from 1% to 47%. Indigenous and plantation forests decreased from 43% to 36% and 34% to 7% respectively. Grassland and shrubland decreased from 16% to 8% and 6% to 2% respectively. Bare ground and built up area had a change of less than 1% each. Causes of pressure that lead to forest degradation included crop cultivation, settlement construction, livestock grazing, charcoal burning, firewood collection, logging, bee keeping and medicinal herbs extraction. Land cover change was more on the eastern side than on the western side. Indigenous and plantation forests were likely to disappear if cropland and built up area expansions were to remain unchecked. The study recommendations were: resettlement activities be eliminated in the Eastern Mau Forest; excision of forest land for crop cultivation should be discouraged; and scientific research should be carried out on sustainable plantation forest activities.

The implementation of the United Nations strategy for “Reducing emissions from deforestation and forest degradation (REDD)” as a mitigation measure to the effects of climate change on forest areas of Colombia, finds support for implementation of international conventions of which the country is part. The methodology applied in REDD projects has conflicts with current regulatory framework, related to the collective ownership of indigenous and afro communities. This paper focus on communities property rights vs. potential REDD forests and their good and environmental services. Conclusions show that the law on coastal areas against forest resource use is limited in Colombia and requires to improve scientific research on normative and regulatory processes focus on economic instruments for biodiversity uses, in order to reduce or take into account the impacts on communities property rights.

Assessment of changes in carbon stock from land use and land cover change in necessary for carbon emissions/removals monitoring and enable countries to comply in line with the Good Practice Guidance of IPCC. This study aimed to estimate and map the historical changes in carbon emission and removal from land use and land cover change from 1986 to 2016 in Sudan savannah ecological zone of Ghana. Nested plot design was applied for field measurement, and Random forest algorithm was used to classify images. The zone was stratified into four Districts and each District further stratified into various land use and land cover (LULC) classes. Emission factors were determined for each LULC. Activity data were obtained from the spatial analysis. The overall carbon released from forest degradation and deforestation was found to be 554,684.96 Mg CO2 or 77.19% with 163,956.93 Mg or 31.84% removed. The inter-annual changes exhibited a decrease from 1986 to 1999, 1999 to 2006 and 2006 to 2016 with value being 642,342.79, 545,125.53 and 445,142.17 Mg CO2, respectively. More CO2 was released from forest degradation and in the area where cropland and forest have been converted to shrub/grassland; whereas carbon was removed in the area where shrub/grassland has been converted to cropland and/or forest land. However, more carbon was recorded in cropland compared to forest and shrub/grassland, which explains the difference in emission factor from carbon. Based on this finding reforestation and REDD+ implementation will be an efficient strategy for sustainable development in the Sudan Savannah ecological zone. In addition, farmers should be encouraged to maintain more trees on their farms to compensate for the forest loss.

The Impact

Forest degradation is attributed to the excessive use of forest resources and extraction, whether for subsistence or commercial purposes. With an increase in human population pressure on forests, forest degradation is becoming a concern for the conservation of biodiversity. The high human dependence on tropical dry forests underscores the need for a complete understanding of the interaction of humans and these forests to ensure their persistence and the wellbeing of the people who depend on these resources. This chapter examines forest resource use and degradation to provide a nuanced understanding of forest degradation and the impact of forest resource use.

Abstract Both observational and modeling studies clearly demonstrate that land-use and land-cover change (LULCC) play an important biogeophysical and biogeochemical role in the climate system from the landscape to regional and even continental scales. Without comprehensively considering these impacts, an adequate response to the threats posed by human intervention into the climate system will not be adequate. Public policy plays an important role in shaping local- to national-scale land-use practices. An array of national policies has been developed to influence the nature and spatial extent of LULCC. Observational evidence suggests that these policies, in addition to international trade treaties and protocols, have direct effects on LULCC and thus the climate system. However, these policies, agreements, and protocols fail to adequately recognize these impacts. To make these more effective and thus to minimize climatic impacts, we propose several recommendations: 1) translating international treaties and protocols into national policies and actions to ensure positive climate outcomes; 2) updating international protocols to reflect advancement in climate–LULCC science; 3) continuing to invest in the measurements, databases, reporting, and verification activities associated with LULCC and LULCC-relevant climate monitoring; and 4) reshaping Reducing Emissions from Deforestation and Forest Degradation+ (REDD+) to fully account for the multiscale biogeophysical and biogeochemical impacts of LULCC on the climate system.

The article deals with the study of the land cover change of Indochina based on the MODIS Land Cover database for 2001—2012. Geospatial land cover data, which are objectively recorded land surface characteristics, are widely used for small-scale mapping of landscapes and ecological systems. The case region of Indochina was selected for the analysis of land cover transformation. In recent decades it has been undergoing active transformation of land use, associated with rapid economic development, substantial population growth, and reorientation of the agricultural sector to foreign markets. The processes of land cover change were studied within the boundaries of zonal types of landscapes, altitudinal zonality spectra, and groups of intrazonal landscapes. The density of changes is uneven in different zonal types of landscapes, the greatest range of transformations is characteristic to the deciduous monsoon forests, semi-evergreen forests (in the subequatorial belt), and within river valleys. The main trajectories of land cover change for 2001—2012 are as follows: 1) expansion of arable areas due to the reduction of forests, savannas and grasslands; 2) the likely increase in the area of perennial plantations (mainly rubber trees and oil palm); 3) forest degradation and spread of savannas; 4) fluctuations of land under shifting cultivation. Since the 2000s commercial production of perennial cash crops is the main cause of deforestation in the region. Land clearing for these needs could have a greater impact on forest cover than logging. The revealed features of land cover change for Indochina made it possible to specify the regional characteristics of the transformation processes as compared to global typology of land coverchanges.
