this study examines the relationship between land use/land cover (lulc) changes and surface runoff generation empirically to reveal how urbanization has altered the hydrologic characteristics of a watershed. a hydrological model, the soil and water assessment tool (swat), is employed to estimate the watershed runoff generation for two lulc scenarios from 2002 to 2010. the cypress creek watershe...

In this paper, a planning analysis of implementing low impact development (LID) type of stormwater best management practices (BMPs) for urban runoff control is presented. The Beijing Olympic Village (BOV) residential area in China was used as a case study. The original BOV stormwater system incorporated some LID BMPs such as porous pavements, green roofs and rainwater cisterns. After the 2008 O...

Plant diseases are considered an important biotic constraint, which leads to significant crop losses worldwide. Integrated disease management (IDM), which combines biological, cultural, physical and chemical control strategies in a holistic way rather than using a single component strategy proved to be more effective and sustainable. In practice and in the majority of cropping systems today, em...

The World Health Organization estimated that more than 60% of the 14 million new cancer cases worldwide in 2012 were reported in the developing part of the world, including Asia, Africa, Central and South America. Cancer survival rate is poorer in developing countries due to diagnosis at late stage and limited access to timely treatment. Since the disease per se cannot be treated even with the ...

Urban flooding is a major problem in many coastal cities. The rapidly shifting patterns of land use and demographic increase are making conventional approaches to stormwater management fail. In developing countries such as Ecuador, lack monitoring, financial constraints absence proper policies exacerbate problems. This work assesses the implementation two Low Impact Development strategies (LIDs...

Poultry housing Improvements to poultry housing systems in developing countries have focused on providing an environment that satisfies the birds’ thermal requirements. Newly hatched birds have a poor ability to control body temperature, and require some form of supplementary heating, particularly in the first few days after hatch. Many developing countries are located in tropical areas where m...

Debt management policy for governments of developing countries must balance conflicting objectives. The structure of explicit and implicit government debt influences the amount of lending private creditors are willing to extend, contractual debt service costs, the probability of default and the costs of default. Because default is not relevant for governments of industrial countries, their debt...

IntroductIon Poultry meat and eggs provide affordable, quality food products that are consumed by most ethnic populations worldwide. Advances in knowledge and technology over recent decades favour the growth and intensification of poultry production in developing countries where there are increasing human populations and economic constraints. Issues related to the environment, human health and ...
