When the Dutch disease met the French connection: oil, macroeconomics and forests in Gabon by Wunder, Sven

“…The central hypothesis of this report is that oil rents have enabled a series of pro-urban, anti-rural policies that, together with the low demographic pressure, have been key in protecting forests from degradation and deforestation. …”

Tropical peatlands management and climate change: a case study in Sumatra, Indonesia by Murdiyarso, Daniel, Suryadiputra, I.N., Wahyunto

“…Peatland development in the tropics including Indonesia is driven by the increasing need for land, food, and fiber under the pressure of population growth. In Sumatra, where peatland covered an area of 7.2 Mha in 1990 was estimated that it has reduced to 6.5 Mha in the recent survey in 2002. …”

Forests, human health and well-being in light of climate change and urbanisation by Hägerhäll, C.M., Ode, A., Tveit, M.S., Velarde, M.D., Colfer, C.J.P., Sarjala, T.

“…In tropical areas, many forest living people who rely heavily on forests in their household economies will be highly vulnerable to forest degradation. Increase in pressure on urban forests and their capacity to provide ecosystem services, reduced availability and quality of recreational areas and higher risk of exposure to vector borne-diseases are some of the effects discussed in this chapter.…”

Policies for reduced deforestation and their impact on agricultural production by Angelsen, A.

“…Local yield increases tend to stimulate agricultural encroachment, contrary to the logic of the global food equation that suggests yield increases take pressure off forests. At national and global scales, however, policy makers are presented with a more pleasant scenario. …”

An overview of forest and land allocation policies in Indonesia: Is the current framework sufficient to meet the needs of REDD+? by Brockhaus, Maria, Obidzinski, K., Dermawan, A., Laumonier, Y., Luttrell, C.

“…More recently, global needs for energy and food have increased pressure on forest land. The REDD+ mechanism is designed to reverse this situation and create opportunities for necessary reforms both inside and outside the forestry sector. …”

From foraging to farming among present-day forest hunter-gatherers: consequences on diet and health by Dounias, E., Froment, A.

“…Although forest ecosystems provide food and medicines to forest dwellers, over the last half-century these ecosystems have undergone unprecedented pressure to make way for economic growth and industrialization, often at the cost of ecological functions that may affect human health, both in short term (i.e. increase in infectious diseases) and long term (incidence of global change). …”

Agrobacterium-mediated transformation of the endophytic fungus Acremonium implicatum associated with Brachiaria grasses by Abello, J.F., Kelemu, Segenet, García, C.

“…In all cases, resistance to the selection pressure (hygromycin B) was maintained. Fluorescence emission was retained by the transformants and also expressed in Brachiaria tissues from plants inoculated with GFP-transformed A. implicatum. …”

Village Baseline Study: Site Analysis Report for Nyando – Katuk Odeyo, Kenya by Onyango, Leah, Mango, Joash, Kurui, Zena, Wamubeyi, B., Orlale, Ruth, Ouko, Edward

“…This is the report of the village baseline study of Kamuana village in the CCAFS benchmark site of Nyando, Kenya, which took place from 18 to 20 May 2011. Population pressure has created land fragmentation and reduction in the area of land that families have under cultivation. …”

Animal production and rainfed agriculture in Asia: Potential opportunities for productivity enhancement by Devendra, C.

“…The projected total meat and milk consumption levels for 2020 are far in excess of anticipated supplies, and place unprecedented pressure on the management of natural resources (crops, animals, land and water). …”

Some implications of a sexual cycle in theileria by Irvin, A.D., Boarer, C.D.H.

“…This potential is greatest in areas where there is a variety of tick and host species which apply different types of selection pressure to parasites. Atypical strains of Theileria are usually isolated from such areas, and although the characteristics of these strains may not be expressed in the wild, unnatural selection by laboratory passage may reveal their presence. …”

Grazing induced biodiversity in the highland ecozone of East Africa by Woldu, Z., Mohamed-Saleem, M.A.

“…The species composition of grazing lands can be influenced by livestock and grazing pressure. A study on manure seed bank was conducted in Ghinchi highland Research Site in Ethiopia between 1995 and 1997. the data on species composition and life-form of the plants germinating in pots receiving air dried manure were compared with species composition of experimental plots in natural grassland subjected to varying grazing intensity. …”

Crop-livestock interactions in the West African drylands by Powell, J.M., Pearson, R.A., Hiernaux, Pierre H.Y.

“…Many semiarid regions of Sub-Saharan Africa (SSA) are experiencing vast increases in human population pressure and urbanization. These augment the demand for agricultural products and have led to the expansion, intensification, and often closer integration of crop and livestock production systems. …”

Growing enough food without enough water by David, S.

“…More food will be required for a growing and wealthier and urbanized population that will put more pressure on water resources. With several water-related limits reached or breached - groundwater decline, shrinking rivers and threatened fisheries - we must ask, 'Will there be enough water to grow enough food? …”

The impacts of climate change on tropical and subtropical horticultural production by Mathur, P.N., Ramírez Villegas, Julián Armando, Jarvis, Andy

“…An increase of 2°C in temperatures will pose a strong pressure on existing crop varieties (temperature thresholds could be exceeded in highly niche-specific and/or temperaturesensitive crops), whilst shifts in rainfall patterns could significantly alter harvests by altering fruit filling periods and delaying vegetative growth, to not speak about the effects of increased CO2 concentrations, the effects on agricultural pests and diseases, and on soil quality, most of which are still highly uncertain and remain under- or unexplored.…”
