This paper examines the various human and non-human factors endangering snail species' population, growth, development and reproduction both in the wild and under domestication; it also highlights the diseases affecting edible snails, conservation consciousness and preventive management practices to be adopted by snail farmers in West Africa in order to ensure the continued existence of these indigenous species with their enormous nutritional, health and economic benefit to mankind.
In recent times, the wild snail species population in West Africa has witnessed a steady decline in its population and biodiversity attributed to the impact of human activities, predators, climatic factors and diseases. With the expected 30% rise in the world’s population from 7.03 billion in 2010 to 9.14 billion in 2030, adequate measures should be taken and adopted to ensure the continued existence of these economic snails biodiversity in the ecosystem. Some of the unsupported snail hunting and population depleting behaviours of the farmers in the region are highlighted and corrected.

Chapter Summaries
Introduction: This chapter introduces the alarming decline in wild snail populations in West Africa, attributing it to human activities, predation, climate change, and diseases. It emphasizes the growing need for sustainable snail farming practices to meet the increasing demand for snail meat and ensure the continued existence of these economically and nutritionally valuable species. The chapter highlights the unsustainable harvesting practices from the wild and the urgent need for controlled breeding and farming.
Risk Factors and Human Activities that affect African Land Snails Population: This section details the significant role of human activities in the depletion of snail populations. Deforestation, the use of pesticides and fertilizers, slash-and-burn agriculture, bushfires, and indiscriminate hunting are identified as major threats. The increasing demand for cheap animal protein and the lack of suitable foundation stock for large-scale farming are further contributing factors. The chapter stresses the destructive impact of human practices on snail habitats and ecosystems.
Climatic Factors Affecting African Land Snail Population in the Humid Tropics: This chapter focuses on the impact of various climatic factors on snail populations. Temperature, humidity, wind, and light intensity are discussed in detail. The chapter highlights the optimal conditions for snail growth and reproduction, emphasizing the negative effects of extreme temperatures, low humidity, strong winds, and unsuitable light levels. The impact of soil type is also examined, emphasizing the need for moist, well-drained soil for optimal snail health.
Predators of African Land Snails in the Humid Tropics: This section discusses the various predators of African land snails, ranging from insects and crustaceans to reptiles, amphibians, rodents, birds, and even humans. The chapter highlights the significant impact of these predators on snail populations, particularly in their natural habitats, underscoring the threats to snail biodiversity and potential species extinction. The diverse range of predators and their feeding behaviors are examined, emphasizing the need for protective measures in snail farming.
Diseases and Parasite affecting African Land Snails in the Humid Tropics: This chapter details the common diseases and parasites affecting African land snails, including fungal, bacterial, and deficiency diseases. It explains the impact of these ailments on snail growth, reproduction, and survival. Cannibalism amongst domesticated snails is also discussed, highlighting the importance of proper management practices to minimize disease outbreaks and ensure the overall health of the snail population. The chapter focuses on the impact of poor hygiene and inadequate farming practices on disease prevalence.
Preventive Measures under Intensive and Semi-Intensive System of Snail Farming: This section outlines practical preventative measures to protect snails from predators and diseases under both intensive and semi-intensive farming systems. This includes securing snail housing, implementing proper netting and fencing, sterilizing soil, and maintaining appropriate humidity levels. The importance of regular soil replacement and the use of trenches filled with deterrents to prevent crawling insects are also stressed, offering a practical guide for farmers.

Frequently Asked Questions: A Comprehensive Language Preview on African Land Snail Populations
What is the main focus of this document?
This document provides a comprehensive overview of factors affecting African land snail populations in the humid tropics. It examines both human-induced and natural influences on snail populations, including risk factors, climatic conditions, predation, diseases, and explores preventive measures for sustainable snail farming.
What are the key themes explored in this document?
The key themes include the impact of human activities (deforestation, pesticides, hunting) on snail populations; the influence of climatic factors (temperature, humidity, wind) on snail survival and reproduction; the role of predation in impacting snail biodiversity; the prevalence and management of snail diseases; and the importance of conservation practices and sustainable snail farming.
What human activities negatively impact African land snail populations?
Human activities like deforestation, the use of pesticides and fertilizers, slash-and-burn agriculture, bushfires, and indiscriminate hunting significantly contribute to the decline of snail populations. The increasing demand for cheap animal protein and unsustainable harvesting practices further exacerbate the problem.
How do climatic factors affect African land snail populations?
Temperature, humidity, wind, and light intensity all significantly influence snail survival and reproduction. Optimal conditions are crucial for growth, while extreme temperatures, low humidity, strong winds, and unsuitable light levels negatively impact snail populations. Soil type also plays a role; moist, well-drained soil is ideal.
What are the major predators of African land snails?
African land snails face predation from a wide range of animals, including insects, crustaceans, reptiles, amphibians, rodents, birds, and even humans. These predators significantly impact snail populations, particularly in their natural habitats, threatening biodiversity and potentially leading to species extinction.
What diseases and parasites affect African land snails?
African land snails are susceptible to various diseases and parasites, including fungal, bacterial, and deficiency diseases. These ailments negatively affect snail growth, reproduction, and survival. Cannibalism among domesticated snails is also a concern. Poor hygiene and inadequate farming practices increase disease prevalence.
What preventive measures are recommended for sustainable snail farming?
Sustainable snail farming requires implementing preventive measures to protect snails from predators and diseases. This includes securing snail housing, using proper netting and fencing, sterilizing soil, maintaining appropriate humidity levels, regularly replacing soil, and employing trenches with deterrents to prevent crawling insects.
What is the overall goal of promoting sustainable snail farming?
Sustainable snail farming is crucial to meet the growing demand for snail meat while ensuring the continued existence of these economically and nutritionally valuable species.
