“…Although several studies have demonstrated the capacity to quantify forest cover change using multitemporal satellite imagery in tropical regions (Skole and Tucker 1993;Moran et al 1994;Mertens and Lambin 1997;Geoghegan et al 2001), to our knowledge, this is the first study in the literature using a remote sensing approach to examine forest cover change during a period of conflict (Suthakar and Bui 2008;Witmer and O'Loughlin 2009).…”

“…Periods of conflict can further deplete or restore forested regions depending on the characteristics, location and duration of the conflict. Two published studies used a remote sensing approach to examine the effects of conflict on land cover change, but primarily focused on changes in agricultural land (Suthakar and Bui 2008;Witmer and O'Loughlin 2009).…”

Examining complexities of forest cover change during armed conflict on Nicaragua’s Atlantic Coast

The effects of armed conflict on biodiversity are an emerging concern in conservation due in part to the occurrence of war in biodiversity hotspots, though few studies have addressed it. We investigate this topic by examining changes in forest cover on the Atlantic Coast of Nicaragua from 1978 to 1993, a period covering their civil war. We predict an increase in forest cover between pre-and post-conflict periods as residents abandoned agriculture plots and migrated from conflict areas. We used a remote sensing approach to detect changes in forest cover area and fragmentation at two study sites. Results confirmed that in the first 5-7 years of the conflict, reforestation was greater than deforestation, but in the latter years of the conflict deforested land almost doubled that which was reforested. Although some forest loss was due to Category 4 Hurricane Joan, several conflict-related factors were partially responsible for these results, such as mass human migration and land reform. Understanding how and why forest cover changes during periods of conflict can help conservationists protect resources both during war and in the tumultuous period following the cessation of violence when nascent governments lack the power to effectively govern and community institutions are fractured by war. In areas where the livelihoods of people are directly dependent on local resources, anticipating ecological and social impacts can help improve future conservation efforts.

“…For example, Landreth and Saito (2014) observed that the traditional balance of homegarden systems is changing as households and communities now often respond to new change drivers by simplifying cultivation to be more commercial, less diverse or by abandoning cultivation altogether. Suthakar and Bui (2008) found that many agricultural lands, including homegardens, were abandoned and regenerated back to forests or bushlands during the war between the government and the LTTE that occurred from 1983 to 2009. Nevertheless, homegardens played a key role during the war and contributed to food security, income generation, and livelihoods in the Northern region of Sri Lanka through the production of a diverse set of vegetables, fruits, herbs, plantation crops, ornamentals, and livestock products (Galhena 2012) and may continuously offer a potential toward establishing small-scale business opportunities for the food insecure portion of the population in this region.…”

What is good about Sri Lankan homegardens with regards to food security? A synthesis of the current scientific knowledge of a multifunctional land-use system

Recently, there has been growing interest in agroforestry systems due to their great potential to mitigate threats to household food and nutrition security from soaring food prices but also as carbon sinks. In Sri Lanka, smallholder farms such as homegardens constitute a majority of Sri Lanka's total annual crop and timber production. Despite Sri Lankan homegardens being considered desirable and sustainable land-use systems, their role in food and nutrition security is not yet entirely understood. By synthesising scientific articles and grey literature we sought the link between food security and homegardens by quantifying their products or services and ascertaining whether food security characteristics are assessed as direct or indirect impacts. The results show that 27 % of 92 identified articles directly quantified aspects that are relevant to food security. Another 51 % of the articles quantified indirect aspects that have relevance for food security, including climate, soil, ecosystem services, structural and floristic diversity and economic aspects. Twenty-two percent of the articles were categorised as being qualitative or conceptual and contained no direct assessments or quantification of food security. The presence of significant merits from homegardens includes providing food security throughout the year at low-cost while sustaining numerous ecosystem services. This benefits particularly the poor farmers. However, many studies are descriptive and only provide location-specific information on single research focuses such as plant species, yield and management. There are few comparisons with crop land, forests or other production systems, and there is even less empirical evidence and quantification of the food security and other benefits. Seven areas where more scientific focus would be beneficial are identified. Homegardens are strong in national policies and to reach a greater level of efficiency within these activities our findings suggest more emphasis on a higher degree of inclusiveness of relevant stakeholders and long-term engagements with context specific guidance.

“…Results indicate that the land use/land cover pattern has been very dynamic since the early 1980s, showing a remarkable decrease in agricultural land use and concomitant increase in non-agricultural land use. The ethnic conflict and its consequences, particularly large-scale population migrations, have been the main driving force for such land use/land cover [44]. Witmer in 2008, applied Landsat Thematic Mapper data and Quickbird imagery to study the effects of war on land use/land cover change in northeast Bosnia.…”
