The key challenges faced are the following: strengthening of equipment, infrastructure, logistics, and the introduction of new vaccines. c) Contribution of national plans and policies to health care and adequate medical treatments 176. The national health development plans place high premium on the issue of access to healthcare services. Thus, the 2011-2020 PNDS, through its strategic orientation No. 8 referred to as “increase in health financing and improvement in financial access by the population to health services”, aims, among others, at reducing the proportion of expenses for services and medicines borne by low-income households. For this purpose, a subsidy of more than one billion six hundred thousand million CFA francs (1 600 000 000) is provided annually by the State for emergency obstetrical and neo-natal care. By means of its strategic orientation No. 5 code-named “development of infrastructure, equipment and health products”, the PNDS should contribute to the reduction of the average radius of theoretical activity of 7.2 km in 2011 to 5km by 2020. d) Protection of individuals and groups from environmental, industrial and occupational risks 177. Climate change has greatly affected the economies and the ecosystems of the geographical space of West Africa, in particular Burkina Faso. The most affected part is the rural sector, as agriculture is affected in particular by soil degradation; irregular and unpredictable rainfall patterns and drought, hence culminating in the decline of productivity of crops and availability of water resources. The effects on this sector have negative consequences on the people since the latter are more than 80% rural. To address this problem, a national multi-risk plan for preparation and response to natural disasters and humanitarian crises was adopted in 2012. It is targeted at fighting against some recurrent phenomena, such as increased temperatures, drought, floods, epidemics, animal and pest diseases, food and nutritional crises. 178. In the area of employment, the Labour Code gives priority to the improvement of working conditions of employees. Thus, in Article 235, every head of service is mandated to take the necessary measures to ensure the protection of the safety, the physical and mental health of workers in his employment including temporary workers, trainees and interns. He must also ensure that the workplace, the machines, the equipment, substances and working procedures under his control do not pose any risks to the health and safety of the workers. According to the statistics of the National Social Security Fund (CNSS), between 2005 and 2009, 10,408 workrelated accidents and occupational diseases were recorded, representing an average of 2 082 cases per year. The compensation paid was in excess of 4 435 406 740 FCFA or an average cost of CFAF 426 154 per occupational risk (Statistical Yearbook of the CNSS No.17- 2009, Page 123 Table 6.1.2, December 2010.). 179. Several structures provide interventions in the area of labour safety and health. They include the following : - The National Technical Advisory Committee on Hygiene and Safety, the advisory opinion of which is required as a matter of obligation for any health and safety-related labour concerns; - The Labour Inspectorate is mandated to oversee basic control and enforcement of hygiene and safety measures in business environments under its territorial jurisdiction.
