Climate change adaptation and sustainable agricultural intensification in developing countries
… resulting in an unprecedented decline in agricultural yields in developing countries. This has threatened the livelihoods of large segments of populations that are heavily dependent on agriculture for survival in these regions. This dissertation focuses on identifying barriers and enablers …

Agricultural intensification, biological pest control and spatio-temporal changes in food web structure
Die Intensivierung der Landwirtschaft ist einer der Hauptauslöser von Verlusten in der Agrarbiodiversität und damit verbundenen Ökosystemfunktionen wie der biologischen Kontrolle. Sie beeinflusst dadurch indirekt auch die landwirtschaftliche Produktionsleistung. Durch die Intensivierung der …

The role of agricultural intensification in modulating ecosystem properties of embedded subtropical wetlands
… especially problematic for wetlands embedded in agricultural systems where surrounding management practices may indirectly impact wetland function and sustainability, including the relative influences on methane emission. The impact of surrounding management intensity on methane emissions from …

Large mammal resource depression and agricultural intensification: an empirical test in the Mimbres Valley, New Mexico
… Valley allocated increasing amounts of time to agricultural tasks, which likely also reduced the efficiency of agriculture, during the same period in which there is evidence of large mammal resource depression. Existing data from the Mimbres Valley are thus consistent with the hypothesis that …

Indirect effects of agricultural intensification on tree swallow (Tachycineta bicolor) foraging behaviour, body condition, and physiology
… link. Declines may be influenced indirectly by agriculturally-driven reductions in the abundance of the swallow’s main diet of aerial insects through increased agrochemical use, wetland drainage and cropping intensity. My objectives were to determine how aerial insect abundance and biomass vary …

Economic analysis of peasant family farms: Agricultural intensification, cost-accounting, and sharecropping in Andean peasant communities
… is motivated by the conditions under which an agricultural surplus can be produced and sustained in nations (LDC's) that are characterized, grosso modo, by a static agricultural technology and rapid growth in demand for agricultural products. Even though peasant family farms comprise as much as …

Pollination in a changing world: function and resilience
… far-reaching impacts on ecosystems worldwide. Agricultural expansion and intensification is a primary driver of terrestrial biodiversity loss, disrupting important ecosystem functions. Paradoxically, agriculture relies strongly on these same ecosystem functions. Animal-mediated pollination is …

Utilizing Remotely Piloted Air Systems in the Delineation of Functional Land Management Zones
… to ensure food security. This necessitates the intensification of agriculture to keep with land resource constraints. Meanwhile, climate change is occurring, and these two factors are exerting pressure on the medium through which food production occurs: the soil. Soil provides many of the …

Land use intensity and trees on farms in Malawi
… in Malawi have put a huge strain on the existing agricultural land and the surrounding woodland. Smallholder agriculture is the dominant economic activity of Malawi’s rural population and many farmers have been forced to cultivate marginal lands with less fertile soils, making conditions much more …

The Maya Footprint: Soil Resources of Chunchucmil, Yucatan, Mexico
<p>Agricultural yields in Northwest Yucatán are constrained by climate, thin soils, and low fertility. Despite this, the ancient Maya city of Chunchucmil Yucatán, Mexico, boasted an immense, dense, and wealthy population during the Middle Classic period (ca A.D. 400-700). Soil physical and chemical …

Compatible components of the integrated pest management of Bathycoelia distincta (Hemiptera: Pentatomidae
… ingredients Furthermore, there is no doubt that agricultural intensification is the primary driver of the loss of biodiversity globally. Therefore, there is a need to develop Integrated Pest Management (IPM) strategies to effectively minimize the damage caused by B. distincta and the loss of …
