Welcome to Elsie J. Zachariah's Website

A flower, sometimes known as a bloom, is the reproduction structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant is called the inflorescence. In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.

Welcome to Climate Change and Agriculture in Africa
Analysis of the impacts of climate change suggests that agro-ecological systems are the most vulnerable sectors. Agriculture in low latitude developing countries is expected to be especially vulnerable because climates of many of these countries are already too hot. Further warming is consequently expected to reduce crop productivity adversely. These effects are exacerbated by the fact that agriculture and agro-ecological systems are especially prominent in the economies of African countries and the systems tend to be less capital and technology intensive. Predictions of impacts across regions consequently suggest large changes in the agricultural systems of low latitude (mostly, developing) countries.















The most beaufiful places which someone can visit; those places which are always ever green are places like Kwazulu Natal, Durban and zululand. You can visit anytime, all seasons are the same.

South Africa's plant life
South Africa's large areas of semi-desert scrub and grassland might suggest a certain poverty of plant life. Aside from the fact that a tract of pristine grassland can hold up to 60 grass species, nothing could be further from the truth.
There are five major habitat types in South Africa: fynbos, forest, Karoo, grassland, and savannah. The country can also be divided into seven biomes, or ecological life zones, with distinct environmental conditions and related sets of plant and animal life: Nama Karoo, succulent Karoo, fynbos, forest, thicket, savanna, and grassland.
Whichever classification is used, some 10% of the world's flowering species are found in South Africa, the only country in the world with an entire plant kingdom inside its borders: the Cape Floristic Kingdom, which contains 8 600 species, 68% of them endemic. The Cape Peninsula alone boasts more plant species than the whole of Great Britain.
