Enjeux fonciers, exploitation des ressources naturelles et Forêts des Communautés Locales en périphérie de Kinshasa, RDC

Journal Articles & Books
Diciembre, 2011
República Democrática del Congo

Land issues, exploitation of natural resources, and Forests of Rural Communities in the periphery of Kinshasa, DRC. Peri-urban forests are under strong anthropic pressure. Any activity needs a previous identification of stakeholders, landscape perception, socio-economic trends in local communities and their relationships with land and natural resources. Kinshasa (capital of Democratic Republic of Congo, DRC) is a 10 millions inhabitants city with rapid growth and increasing impacts on surrounding villages linked with forest natural resources.

Hoofbeats From the Currituck Outer Banks: A Study of the Corolla Wild Horse Fund Adoption Program

Journal Articles & Books
Diciembre, 2016

Research on the adoption and relinquishment of horses, both domestic and wild, remains limited. As a result, little is known about adopters, their adopted horses, and their adoption experience. This study surveyed and interviewed 17 adopters of Colonial Spanish mustangs through the Corolla Wild Horse Fund (CWHF). Together, they adopted 22 horses of varying ages and genders from 2002 to 2012. The participants, who had a range of previous experience with and knowledge of horses, were generally very satisfied with their horses and their adoption experience.

Minimising the harm to biodiversity of producing more food globally

Journal Articles & Books
Diciembre, 2011

Should farming and conservation policies aim broadly to separate land for nature and land for production (land sparing) or integrate production and conservation on the same land (wildlife-friendly farming)? Most studies that try to address this question suffer from flaws in sampling design, inappropriate metrics, and/or failure to measure biodiversity baselines. We discuss how these failings can be addressed, and what existing information tells us about the key debates on this topic. The evidence available suggests that trade-offs between biodiversity and yield are prevalent.

Nowadays, as a result of economic and social reasons, people decide to live in big cities and this situation causes great population growth. Depending on this growth, green fields which have multi functions that increasingly remains insufficent.

Perceptions of Power and Manner of Designation: Impacts on Trust

Journal Articles & Books
Diciembre, 2015

The two key factors of (1) how local interests should be weighed in public land management and (2) the manner in which public land designation occurred have been overlooked in research on trust in federal land management agencies. The literature also tends to focus solely on direct relationships between various predictors of trust, rather than examining indirect relationships.

Impact of Sampling Depth on Differences in Soil Carbon Stocks in Long-Term Agroecosystem Experiments

Journal Articles & Books

Canadá

The depth of sampling has recently been highlighted as critical to making accurate measurements of changes in SOC stocks. This paper aimed to determine the effects of land management changes (LMC) on soil organic carbon (SOC) by re-sampling long-term agoecosystem experiments (LTAEs) across Canada using identical sampling and laboratory protocols. The impact of sampling depth on the monitoring of LMC-induced differences in SOC stock in LTAEs in Canada, and the implications on statistical power and sampling design, were assessed.

Differential evolution algorithm for solving multi-objective crop planning model

This study presents four strategies of a novel evolutionary algorithm, multi-objective differential evolution algorithm (MDEA). The four strategies namely, MDEA1, MDEA2, MDEA3 and MDEA4 are adapted to solve the multi-objective crop planning model with multiple constraints in a farmland in the Vaalharts irrigation scheme (VIS) in South Africa. The three objectives of the model are to minimize the total irrigation water (m²) and to maximize both the total net income in South African Rand (ZAR) from farming and the total agricultural output in tons.

Environmental and management factors determining weed species composition and diversity in France

Journal Articles & Books

Francia

Multivariate analysis of data from approximately 700 arable fields from France was carried out to partition the respective importance of environmental factors versus management practices on weed species richness and composition. Overall, canonical correspondence analysis indicated that the major variations in species composition between fields were associated with human management factors; (1) the current crop type and (2) the preceding crop type. Three main weed communities were identified according to sowing season: winter, spring and summer-sown crops.

Furrow diking in conservation tillage

Journal Articles & Books
Diciembre, 2010

Crop production in the Southeastern U.S. can be limited by water; thus, supplemental irrigation is needed to sustain profitable crop production. Increased water capture would efficiently improve water use and reduce supplemental irrigation amounts/costs, thus improving producer's profit margin. We quantified infiltration (INF), runoff (R), and sediment (E) losses from furrow diked (+DT) and non-furrow diked (−DT) tilled conventional (CT) and strip tillage (ST) systems. In 2008, a field study (Tifton loamy sand, Typic Kandiudult) was established with DT, ST, and CT systems.

Quantifying the impact of land-use change to European farmland bird populations

The EU has adopted the European Farmland Bird Index (EFBI) as a Structural and Sustainable Development Indicator and a proxy for wider biodiversity health on farmland. Changes in the EFBI over coming years are likely to reflect how well agri-environment schemes (AES), funded under Pillar 2 (Axis 2) of the Common Agricultural Policy, have been able to offset the detrimental impacts of past agricultural changes and deliver appropriate hazard prevention or risk mitigation strategies alongside current and future agricultural change.
