This guide is motivational and inspiring to the students, weed control managers, communities and others. With great effort, the author describes the weed and weed characters in simpler terms to reach the common people. Eight aquatic invasive weeds have been prohibited in Botswana and their movement within the country is restricted as per the Aquatic Weed (Control) Act of 1986, Botswana. The readers draw attention to how these weeds can be identified in the field and how they can be managed with integrated control measures. With the information presented, we all need to cultivate feelings of protecting our waters and wetlands so that the integrity of the ecosystems is restored. Fears are spread too generously about the threat of aquatic weeds, but there are well-practiced norms, laws and methods available to manage them. The strategies and goals of the Aquatic Weed Control practiced in wetlands of Botswana to manage the weeds and the results obtained from the program can provide confidence in weed control programs for several countries. It is set out how natural selection underlies the great similarities between species and how, when species are isolated as invasive, they become different. With this principle, the author presents, through natural measures, how evolutionary changes can occur in a system where the weeds are controlled.
An anthology of aquatic plants is an excellent collection of knowledge about anything in fresh, marine, or polluted waters. This pictorial guide deals with aquatic and wetland plants from the Okavango to the transboundary rivers to the rainwater ponds and dams. Organized and written in a way that will make information easily accessible to specialists and non-specialists alike. The guide/book highlights the diversity and vital ecological importance of the group of plants, providing descriptions and identification keys for emergent, floating-leaved, and submerged aquatic plants found in Botswana. They serve as a source of food and shelter for the aquatic fauna, thus forming the basis of aquatic wildlife conservation practices. They are economically useful in providing medicinal and aesthetic value. Aquatic plants prevent and maintain erosion, water turbidity, and the source of oxygen in the water. Information on invasive plants, such as Kariba/salvinia weed, water lettuce, and water hyacinth that threaten Botswana's aquatic ecosystems, is briefly described. In total, 194 plant species are presented in the guide. All technical terms are explained in a comprehensive glossary. This is the first such flora to cover aquatic and wetland plants for the entire geographical area, excluding grasses and sedges. It will suit a large age range, from little ones who want to look at the pictures to primary school children. If you have an explorer's spirit and a thirst for finding something new, then aquatic life will never disappoint. The physical book itself is stunning, with a handsome cover with common water lily that makes it pretty enough to sit on the coffee table but entertaining enough to keep kids glued to the pages. When the two characters from a different native, who rose in the same city of Aizawl, meet and fall in love during PUC, his jealous gay friend circles a rumor and tries to interfere in their affairs. Her love sadly feels unrequited due to his shy and reclusive nature followed by some tragic incidents that make all her attempts go in vain. She also doesn’t understand his gesture of acceptance and things remain in a state of oblivion for a long time. Her sedulousness doesn’t allow giving up on him even after they part ways to pursue their higher studies. But her naiveness again fails her in catching his clues before he turns into a severe hophead after his mother’s demise. A lot changes in their lives by the time he comes close to expressing his hidden love for her and is about to propose for marriage. Despite both being settled in the South, every time some divine energy would stop them from meeting in one place. Unease in his mind, he starts revealing his feelings and relevant secrets after his marriage and comes to a point when she learns how life had been unkind to both of them and they begin expressing their regrets. It is a tragic love story that starts with love and ends with friendship. After reading the book, you might wonder whether they will remain just as incomplete stories that are waiting to be completed like how they called themselves.
This report is the result of a joint project of the Southern African Development Community (SADC), the World Bank, the International Bank for Reconstruction and Development, Swedish International Development Agency (Sida) and the World Conservation Union (Regional Office for Southern Africa) which investigated the threats to precious water resources in southern Africa, and to the environment that sustains them. The full colour, glossy report was intended as a SADC contribution to the United Nations summit on Sustainable Development in Johannesburg in 2002, and to the New Partnership for Africa's Development. The report provides a framework for the sustainable management of water resources, and presents solutions for long-term protection and appropriate utilisation of water in the counties of the region ? the DRC, Angola, Tanzania, Zambia, Malawi, Zimbabwe, Mozambique, Namibia, Botswana, Swaziland, Lesotho and South Africa. Some key messages that pervade the report are: firstly that the effective and sustainable utilisation and management of water resources are essential prerequisites for sustaining all forms of life and livelihoods, and for fostering overall socio-economic development and poverty reduction in the region; and that moreover, sustainable water resources management must be balanced between the short-term needs of the people and their human development, and the protection of the natural resource base and environment.
This new, thoroughly updated sixth edition of Bradt’s Botswana Safari Guide remains the only full-blown, standalone guide to one of Africa’s most popular and rewarding safari destinations. This is the sole guide to focus on Botswana’s key safari locations: the Okavango Delta, Chobe National Park and the Northern Kalahari. Botswana’s wilderness is pristine, a virtue underpinned by governmental commitment to sustainable tourism. The Okavango Delta’s permanent waters attract year-round wildlife, including all the ‘big five’. Outside the Delta, this English-speaking country offers tremendous variety in landscapes, from the arid Kalahari to lush forests. Riverine areas harbour spectacular herds of elephants and buffalo, as well as mighty predator populations. Dusty savannahs attract hardier game such as oryx and springbok. On Makgadikgadi’s great salt pans, zebras gather in huge congregations after rain. Birdwatching is brilliant throughout. Then there’s Botswana’s rich history, from the ancient rock paintings at the Tsodilo Hills to Stone Age arrowheads on the Makgadikgadi Pans. Bradt’s Botswana Safari Guide offers detailed descriptions of many lodges, from traditional tented camps to those offering five-star luxury and top-class cuisine, plus detail on what animals occur where, enabling you to select the optimum approach. With this book’s comprehensive GPS co-ordinates and detailed maps, independent travellers can drive themselves around. But perhaps you prefer bespoke mobile safaris with a private guide? Either way, take a night drive to see creatures of the dark: genets and hunting leopards. For a different feel, explore rivers on gentle motorboat cruises, including on multi-day trips, or get closer to the water in a traditional mokoro (dug-out canoe), with a poler escorting you along shallow waterways. Or seek out a specialist walking camp for the excitement of bush walks – when meerkats might even pose atop your head for a great lookout. And why not use this book’s advice to book-end trips by visiting Livingstone (Zambia) and the Victoria Falls? Written and updated by Chris and Susie McIntyre, experts on all things Africa, Bradt’s Botswana Safari Guide is the definitive companion to discovering this thrilling destination.
CD ROM to accompany this book available from Library Office.
In this book recent scientific development and politico-institutional experiences related to the conservation of the South-American Pantanal are explored in relation to what is happening in other tropical wetland areas of international importance such as the Everglades in North America and the Okavango in Africa, as well as considering the European experience. An interdisciplinary group of authors examines the need to establish a constructive dialogue between scientists, policy-makers and local stakeholders and outline a future research agenda.
This book discusses the biological control of weeds using arthropods, providing ecological management models for use across the tropical world.
